ITEMS 1. AND 2. BUSINESS AND PROPERTIES

OUR BUSINESS

VISION AND STRATEGY

We are a North American mining company engaged in the full mining cycle, which includes acquisition, exploration, development and operation of mineral properties. In the past several years, we have evolved from being a major primary molybdenum producer to becoming a copper and gold mining company with the construction and development of our principal operating asset, our open-pit copper-gold mine and concentrator in British Columbia, Canada (“Mount Milligan Mine”). Mount Milligan Mine commenced commercial production in February 2014 and achieved design capacity at year-end 2015. At December 31, 2015, the combined proven and probable estimated mineral reserves for Mount Milligan Mine totaled 2.2 billion pounds of contained copper and 5.7 million ounces of contained gold (506.4 million tonnes at 0.196% copper and 0.349 grams per tonne gold).

In 2015, we shifted the core focus of our business to copper and gold while at the same time developing a strategy to maintain the optionality of our molybdenum business. This shift in core focus was primarily the result of expected ongoing weakness in the molybdenum market due to an overall weak global economy for molybdenum products. During 2015, we sold inventory produced at our molybdenum mines in 2014 and continued to operate our metallurgical facility in Pennsylvania, USA (the “Langeloth Facility”), roasting third-party molybdenum concentrate and other metals. In 2016, we expect to generate sufficient revenue from the Langeloth Facility to substantially cover care and maintenance costs of our molybdenum mines. Please see "Molybdenum Mines" below.

Our current business strategy is to:


•	conduct our operations safely and in an environmentally responsible manner;


•	optimize operations at Mount Milligan Mine and maximize the value of the asset;


•	execute a plan to address our outstanding debt and strengthen the balance sheet;


•	maintain the optionality of our molybdenum business; and


•	improve our competitive position in the industry.

In the medium term, we intend to seek opportunities to enhance our diverse production profile through accretive acquisitions and/or investments.

Table of Contents

COPPER AND GOLD BUSINESS

In August 2013, the start-up of operations began at the Mount Milligan Mine with the first feed to the concentrator, and in September 2013, the first copper-gold concentrate was produced. Mount Milligan Mine reached commercial production as of February 18, 2014, defined as operation of the mill at 60% of design capacity mill throughput for 30 days. At year-end 2015, we achieved and on occasion exceeded design mill throughput of 60,000 tonnes per day ("tpd"). In 2015, we utilized a temporary secondary crushing facility to help us achieve design throughput. As previously disclosed, we have determined that a permanent secondary crushing circuit will provide more reliable throughput levels for the long-term at lower cost than what we can achieve with the temporary secondary crushing circuit. We have made the decision to move forward with the construction of the permanent secondary crushing circuit which we expect will enable us to consistently achieve average daily throughput of approximately 62,500 tpd. The permanent secondary crushing circuit is expected to be completed in the fourth quarter of 2016. In the fourth quarter of 2015 we made the decision to order the long-lead items for the permanent crusher and take additional steps in preparation for construction, and in February 2016 we made the decision to commence construction. The total capital cost estimate for the project is approximately $60 - $65 million, inclusive of approximately $15.0 million incurred in 2015 for engineering and concrete work and long lead items. Of the amount incurred in 2015, approximately $6.2 million was accrued as of December 31, 2015. See Item 7 “Management's Discussion and Analysis of Financial Condition and Results of Operations” for additional information.

MOLYBDENUM BUSINESS

Until the Mount Milligan Mine became operational in the fall of 2013, our business was primarily focused on the extraction, processing, roasting, and sale of molybdenum. Through the end of 2014, we operated an open-pit molybdenum mine and concentrator in Idaho, USA (“TC Mine”), and an open-pit molybdenum mine, and concentrator in British Columbia, Canada, in which we own a 75% joint venture interest (“Endako Mine”). TC Mine was placed on care and maintenance in December 2014 after the mining and processing of ore from Phase 7 was completed. Effective December 31, 2014, operations at Endako Mine were temporarily suspended due to ongoing weakness in the molybdenum price, and, effective July 1, 2015, Endako Mine was placed on care and maintenance. For more information regarding severance and other costs relating to care and maintenance of TC Mine and Endako Mine, please see Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Form 10-K.

In 2015, we transformed our business strategy for molybdenum to maximize the location and efficiency of our Langeloth Facility. We provide tolling services for customers by converting molybdenum concentrates to molybdenum oxide powder and briquettes and ferromolybdenum products. Additionally, we purchase molybdenum concentrates to convert to upgraded products which are then sold in the metallurgical and chemical markets. Langeloth is one of the largest molybdenum conversion plants in the world, with 36 million pounds of annual roasting capacity and the ability to produce 9.5 million pounds of ferromolybdenum (one of only two such plants in the United States and one of only three in North America), as well as 3 million pounds of pure moly oxide and 6,000 pounds of rhenium. Langeloth’s quality is recognized throughout the world, especially in the United States. Over the past three years, Langeloth has sold molybdenum products to Brazil, European Union, Russia, Korea, Japan, India and China in addition to North America. Langeloth’s wide ranging customer base is a testament to its quality and reputation. We believe Langeloth is well positioned to offer North-American and other customers a number of competitive advantages relative to other large conversion plants operating in South America.

As of January 2016, we operate a commercial molybdenum beneficiation circuit at TC Mine to treat molybdenum concentrates to supplement the concentrate feed we source directly for the Langeloth Facility. This follows a series of test runs in 2015 with a variety of different concentrates, as a result of which we concluded that we could profitably process high copper molybdenum concentrate through a beneficiation process at TC Mine, which is then transported to Langeloth for processing.

GENERAL

We were organized in 2000 as a corporation under the laws of Ontario, Canada, and were continued as a corporation under the laws of British Columbia, Canada in 2008. We are a corporation governed by the Business Corporations Act (British Columbia). In October 2006, we acquired Thompson Creek Metals Company USA, then a privately-held company incorporated and headquartered in the United States, and in so doing acquired TC Mine, Endako Mine and the Langeloth Facility. In October 2010, we acquired Terrane Metals Corp. (“Terrane”) and in so doing acquired the Mount Milligan development project, which is now Mount Milligan Mine. Through the Terrane acquisition we also acquired a copper, molybdenum and silver exploration property located in British Columbia, Canada (the “Berg Property”). Our corporate headquarters are in Littleton, Colorado, USA.

The following map sets forth the locations of our mines, metallurgical facility, exploration properties and corporate office:

See the Notes to the Consolidated Financial Statements, "Financial Statements and Supplementary Data" of this report, for financial information about our operating segments and by geographic area.

PRODUCTS

Our principal products in 2015 were copper and gold. In 2015, we produced 75.2 million pounds of copper in concentrate, containing 71.4 million pounds of payable copper, and 225,992 ounces of gold in concentrate, containing 218,081 ounces of payable gold. In 2015, 2014 and 2013 approximately 33%, 22% and 2%, respectively, of our product sales were attributable to copper, and approximately 45%, 22% and 1%, respectively, of our product sales were attributable to gold.

We sold 12.1 million pounds of mined (primarily from 2014 inventory) and purchased molybdenum in 2015. In 2014, 2013 and 2012, approximately 22%, 56% and 97% of our product sales were attributable to molybdenum.

Copper and Gold

Concentrate Sales

We produce copper and gold in a saleable concentrate at our Mount Milligan Mine and sell the concentrate to third parties, including smelters and traders, which we refer to as “MTM Customers.” We are currently party to four multi-year concentrate sales agreements. Pursuant to these agreements, we have agreed to sell an aggregate of approximately 120,000 tonnes in 2016, 60,000 tonnes in 2017 and 40,000 tonnes in 2018.

Pricing under these concentrate sales agreements will be determined by reference to specified published reference prices during the applicable quotation periods. Payment for the concentrate will be based on the price for the agreed copper and gold content of the parcels delivered, less smelting and refining charges and certain other deductions, if applicable. The copper smelting and refining charges will be negotiated in good faith and agreed by the parties for each contract year based on terms generally acknowledged as industry benchmark terms. The gold refining charges are as specified in the agreements. Remaining concentrate produced at Mount Milligan Mine will be sold under short-term contracts or on a spot basis.

The commitments under our current multi-year concentrate sales agreements cover approximately 90% of our expected concentrate production in 2016 and are also less than the total expected production in 2017 and beyond. We intend to either extend our current multi-year agreements as the terms expire, or we may enter into additional multi-year sales agreements. To the extent that production is expected to exceed the volume committed under these agreements, we will sell the additional volume under short-term contracts or on a spot basis.

Arrangement with Royal Gold

Pursuant to an agreement dated October 2010 and last amended in December 2014, with a subsidiary of Royal Gold, Inc. (“Royal Gold”) (referred to as the “Gold Stream Arrangement”), we agreed to sell to Royal Gold 52.25% of the refined gold production from Mount Milligan Mine for a total upfront payment of $781.5 million, plus $435 per ounce, or the prevailing market rate if lower than $435 per ounce, when the gold is delivered. We used the funds we received from Royal Gold in our purchase of Terrane and in the construction of the Mount Milligan Mine. To satisfy our obligations under the Gold Stream Arrangement, after we sell copper and gold concentrate from Mount Milligan Mine to MTM Customers, we purchase gold ounces in the market for delivery to Royal Gold in an amount based on a portion of the gold ounces in the copper and gold concentrate sold to MTM Customers, as determined in accordance with the terms of the Gold Stream Arrangement. For more information about the Gold Stream Arrangement, please see Note 10.

Markets

Copper is a malleable and ductile element that is an excellent conductor of heat and electricity as well as being corrosion-resistant and antimicrobial. Refined copper is incorporated into wire and cable products for use in the construction, electric utility, communications and transportation industries. Copper is also used in industrial equipment and machinery, consumer products and a variety of other electrical and electronic applications and is also used to make brass. Copper substitutes include aluminum, plastics, stainless steel and fiber optics. Refined, or cathode, copper is also an internationally traded commodity. A combination of current mine production and recycled scrap material make up the annual copper supply. Copper is an internationally traded commodity, and its prices are determined by the major metals exchanges: the LME, the Shanghai Futures Exchange and the COMEX division of the New York Mercantile Exchange. Prices on these exchanges generally reflect the worldwide balance of copper supply and demand and can be volatile and cyclical. In general, demand for copper reflects the rate of underlying world economic growth, particularly in industrial production and construction.

Gold generally is used for fabrication or investment. Fabricated gold has a variety of end uses, including jewelry, electronics, dentistry, industrial and decorative uses, medals, medallions and official coins. Gold investors may buy gold bullion, official coins or jewelry or invest through options, futures or exchange-traded funds. A combination of current mine production, recycling and draw-down of existing gold stocks held by governments, financial institutions, industrial organizations and private individuals make up the annual world-wide gold supply. The price of gold is volatile and is affected by numerous factors. Factors affecting the market for gold include the sale or purchase of gold by various central banks and financial institutions, inflation, recession, fluctuation in the relative values of the US dollar and foreign currencies, changes in global and regional gold demand and political and economic conditions throughout the world.

Molybdenum

Our principal molybdenum products are molybdic oxide (also known as roasted molybdenum concentrate) and ferromolybdenum. Other products we produce include high soluble technical oxide, pure molybdenum trioxide and high purity molybdenum disulfide. Prior to December 31, 2014, we sourced molybdenum from our two primary mines, TC Mine and Endako Mine, and from third-party producers. As of January 1, 2015, our principal source for molybdenum concentrate was sourced from by-product production from copper mines in North and South America. In addition to toll converting such concentrate for third party suppliers, we also purchase this concentrate to upgrade and sell to other customers.

Markets

Molybdenum is an industrial metal principally used for metallurgical applications as a ferro-alloy in steels where high strength, temperature-resistant or corrosion-resistant properties are sought. The addition of molybdenum enhances the strength, toughness and wear and corrosion-resistance in steels when added as an alloy. Molybdenum is used in major industries including chemical and petro-chemical processing, oil and gas for drilling and pipelines, power generation, automotive and aerospace. Molybdenum is also widely used in non-metallurgical applications such as petroleum refining catalysts, lubricants, flame-retardants in plastics, water treatment and as a pigment. A combination of current mine production and recycled scrap material make up the annual molybdenum supply. Molybdenum is mined from both primary mines, ones that contain only molybdenum as an economic mineral, and as a by-product from certain copper mines.

Molybdenum prices are determined by transacting parties rather than by a metals exchange. Reference prices for molybdenum are available in several publications, including Platts Metals Week, Ryan’s Notes and Metal Bulletin. Molybdenum prices generally reflect the worldwide balance of molybdenum supply and demand and can be volatile and cyclical. In general, demand for molybdenum reflects the rate of underlying world economic growth, particularly in industrial production and construction.

SOURCES AND AVAILABILITY OF RAW MATERIALS

Our mining operations require significant energy, principally electricity, diesel and natural gas. Most of our energy is obtained from third parties under long-term contracts. Our mining operations also require significant quantities of water for mining, ore processing and related support facilities. Although we believe we have sufficient energy sources and water rights to conduct our mining operations, the loss of electricity or water rights for any of our mines, in whole or in part, or shortages of such resources, could require us to curtail or shut down mining operations. For a further discussion of risks associated with the availability of water, refer to Item 1A. “Risk Factors.”

Table of Contents

COMPETITION

The mining industry is intensely competitive. Our competitive position is based on the quality and grade of our mineral reserves, our operating results, our ability to manage our costs compared to other producers throughout the world, our ability to maintain our financial integrity through the lows of the metal price cycles, our ability to attract and retain skilled employees, and our ability to manage our customer relationships. Our costs are governed to a large extent by the location, grade and nature of our estimated mineral reserves, our input costs, including energy, labor, and equipment, and our operating and management skills. The metals markets are cyclical, and our ability to maintain our competitive position over the long term is based on our ability to manage our costs and our debt levels, given the cyclical markets, acquire and develop quality deposits, and hire and retain a skilled workforce. Our substantial indebtedness will limit our ability to significantly grow our business in the near term.

Until we began producing concentrate from Mount Milligan Mine in late 2013, we exclusively mined molybdenum, and were thus subject to unique competitive advantages and disadvantages related to the price of molybdenum. As discussed above, the core focus of our business has shifted to copper and gold and away from molybdenum, which makes us less sensitive to fluctuations in the price of molybdenum but increases the effects of fluctuations in copper and gold prices on our business. Please see Item 1A, "Risk Factors" for further discussion regarding risks that may affect our competitive position.

EMPLOYEES

As of December 31, 2015, we employed approximately 700 people (approximately 475 in Canada and 225 in the United States).

Approximately 66% of employees at the Langeloth Facility are members of the International Union, United Automobile, Aerospace and Agricultural Implement Workers of America union through its Local 1311. Collective bargaining has commenced with the union at the Langeloth Facility for a new collective agreement to replace the current labor agreement which is set to expire on March 11, 2016. Approximately 18% of Endako Mine’s employees are members of the United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union through its Local 1-424. In January 2014, a collective agreement was reached with the union at Endako Mine for the period from April 1, 2013 to March 31, 2015. The collective agreement automatically renewed and will continue under existing terms, unless either party gives 90 days' written notice prior to the expiration of the then-current term requiring the other party to commence collective bargaining for a renewal agreement. We believe that our relations with all of our employees are good.

ENVIRONMENTAL, HEALTH AND SAFETY MATTERS

Environment

Our mining and exploration activities are subject to extensive federal, provincial, state and local laws, regulations and permits governing protection of the environment. Among other requirements, our Canadian operations must comply with authorizations issued under the Mines Act and the Environmental Management Act. We also implement Fish Habitat Compensation Plans at Mount Milligan Mine under the Fisheries Act and the Metal Mining Effluent Regulations. In the United States, TC Mine has permits issued under the federal Clean Water Act and Clean Air Act. Our tailings storage facility at TC Mine is governed by an Idaho statute and dam safety permit administered by the Idaho Department of Water Resources. Our primary permits at the Langeloth Metallurgical Facility are issued under the federal Clean Water Act and Clean Air Act, both of which are implemented in Pennsylvania by the state Department of Environmental Protection.

Our policy is to conduct business in a way that safeguards public health and the environment. We believe that our operations are in compliance with applicable environmental laws and regulations in all material respects. Regular monitoring and compliance with periodic reporting requirements are integral components of all our environmental permits and authorizations. In Canada, we also conduct Environmental Effects Monitoring, which is a cyclical receiving-environment monitoring program to assess the potential effects of effluent on fish populations, benthic invertebrates and periphyton.

The costs associated with implementation and compliance with environmental requirements are substantial. Possible future legislation, regulations, policies or guidance could cause additional operating expense, capital expenditures, restrictions and delays in the development and continued operation of our properties, the extent of which cannot be predicted with certainty. In the context of environmental permitting, including approval of reclamation plans and compliance with long-term, post-reclamation obligations, we are required to comply with known standards and regulations, which may entail significant costs. For further discussion of risks associated with environmental matters, refer to Item 1A. “Risk Factors.”

Table of Contents

Estimated future reclamation costs are based primarily on legal and regulatory requirements. As of December 31, 2015, we have provided financial assurance for reclamation costs of approximately $42.3 million at TC Mine, $11.1 million at Endako Mine (of which our 75% share is approximately $8.3 million) and $21.7 million for Mount Milligan Mine. Environmental laws and regulations generally have become more stringent and restrictive during the life of our operations. Our reclamation obligations and the related financial assurances we are required to provide will likely increase over time. We will continue to maintain the required reclamation security at both molybdenum mines during the care and maintenance period. Similarly, we will conduct all environmental monitoring and reporting required by all permits and by regulation during this time.

Health and Safety; Corporate Responsibility

We are committed to ensuring the health and safety of our employees and operating in a sustainable, socially responsible manner. We have updated and adopted a Safety, Health and Environmental Commitment Policy under which we have, among other things, implemented systems to provide ongoing safety training, promote a proactive safety culture among our employees, and encourage open communication to improve operating practices affecting health and safety. To help us achieve one of our most important goals and in an effort to be a “Leader in Safety” among our peers, we have launched a Company-wide Safety and Leadership Initiative, which combines behavior-based safety systems with the development of a safety-centric culture and safety leadership training. The initiative was first implemented at TC Mine in 2012 and resulted in improved safety performance. In 2015, we rolled out the initiative at our remaining sites, including the corporate office. The results have shown a dramatic improvement in safety performance with our Company wide All Incident Reportable Rate improving from 2.48 during 2013 to 0.67 during 2015. The Mount Milligan Mine continues to implement an Environmental, Health and Safety Management System that is intended to comply with ISO 14001:2004 and OHSAS 18001.

In addition, we have adopted a Corporate Responsibility Policy that reflects our commitment to conducting business in a manner that, among other things, maximizes positive impacts within the workplace for our employees and within the communities in which we work and live. We have developed plans and programs to promote sustainability in our business and are committed to building long-term relationships with the communities in which we operate. At Mount Milligan Mine, a Community Sustainability Committee, which consists of representatives from the Company, local communities and First Nations, has met quarterly since 2008.

Our annual Corporate Responsibility Report for 2015 will be published and available in May 2016. When available, it may be accessed on the “Responsibility” page of our website at www.thompsoncreekmetals.com. The Safety, Health and Environment Committee of the Board of Directors is responsible for overseeing the development and implementation of the Safety, Health and Environmental, Commitment Policy, the Corporate Responsibility Policy and other related policies. The Committee also reviews the performance of the Company with respect to environmental, health and safety matters. Information regarding our performance is made publically available in our Corporate Responsibility Report.

OUR MINES

MOUNT MILLIGAN MINE (COPPER AND GOLD)

General

Mount Milligan Mine is a conventional truck-shovel open-pit copper and gold mine and concentrator with a 60,000 tpd design capacity copper flotation processing plant. We have made the decision to move forward with the construction of the permanent secondary crushing circuit which we expect will enable us to consistently achieve average daily throughput of approximately 62,500 tpd. The permanent secondary crushing circuit is expected to be completed in the fourth quarter of 2016. Mount Milligan Mine has an estimated life of approximately 22 years (based on spot metal prices of $2.95 per pound copper and $1,250 per ounce gold) and estimated average annual production of 84 million pounds of copper and 185,000 ounces of gold in 159,000 tonnes of concentrate, over the life of the mine. As of the date of this Form 10-K, Mount Milligan Mine is our only material mineral property. On January 21, 2015, we filed an updated National Instrument 43-101 ("NI 43-101") technical report for Mount Milligan Mine. Please see "Mineral Reserves" below for more information, including a discussion of certain factors taken into consideration in determining the economic viability of the mine.

In October 2010, we acquired the Mount Milligan development project as part of our acquisition of Terrane, and began construction shortly thereafter. On August 15, 2013, the start-up of the mine operation began with the first feed to the concentrator, and in September 2013, the first copper-gold concentrate was produced at the mine. Mount Milligan Mine reached commercial production as of February 18, 2014, defined as operation of the mill at 60% of design capacity mill throughput for 30 days. At year-end 2015, we achieved and on occasion exceeded design mill throughput of 60,000 tpd.

Mount Milligan Mine is located within the Omenica Mining Division in North Central British Columbia, Canada, approximately 153 kilometers northwest of Prince George, 80 kilometers north of Fort St. James and 97 kilometers west of Mackenzie. Mount Milligan Mine is accessible by commercial air carrier to Prince George, British Columbia, then by vehicle from the east via Mackenzie on the Finlay Philip Forest Service Road and the North Philip Forest Service Road, and from the west via Fort St. James on the North Road and Rainbow Forest Service Road. Road travel to the Mount Milligan property site is 776 kilometers from Prince Rupert and 254 kilometers from Prince George. The communities of Mackenzie and Fort St. James are within daily commuting distance of the Mount Milligan site, and both of these communities are serviced by rail. The infrastructure at Mount Milligan Mine includes a concentrator, a tailings storage facility and reclaim water ponds, an administrative building and change house, a truck shop/warehouse, a permanent operations residence, a first aid station, an emergency vehicle storage, a laboratory and sewage and water treatment facilities. The power supply is provided by B.C. Hydro via a 92-kilometer power line. We transport concentrate from the mine site to Mackenzie via truck, and from there by railway to the port of Vancouver for shipment to MTM Customers.

Mount Milligan Mine includes 107 claims and one mining lease with a combined area of 49,726 hectares. The single mining lease that was issued to Terrane on September 9, 2009, expires on September 9, 2029, and requires a lease payment of approximately $102,000, due annually on September 9. Mineral claims are subject to exploration expenditure obligations, or we may choose to pay annual fees to the Province in lieu of exploration expenditures. All mineral claims are in good standing with expiry dates of March 2017 and March 2018. We expect to renew such mineral claims in the ordinary course.

A 2% net smelter return royalty, commencing in the third year of commercial production, is payable to a previous owner of the property. The royalty holder, H.R.S. Resources Corp. (successor in interest to Richard Haslinger), had the right to receive annual advances of C$20,000, first payable on or before December 31, 1994, and on each anniversary after the first advance until the commencement of commercial production. We have a right of first refusal on any proposed disposition of the net smelter return royalty by H.R.S. Resources Corp.

We have also agreed to make certain payments to the McLeod Lake Indian Band over the life of the mine. We do not consider the amounts of these payments to be material to our business. The terms of the Socio-Economic Agreement under which we make these payments are confidential.

As described above, we have entered into a Gold Stream Arrangement with Royal Gold pursuant to which we committed to sell an aggregate of 52.25% of the refined gold production from Mount Milligan Mine to Royal Gold. For more information about these transactions, see Note 10.

History

Limited exploration activity on Mount Milligan was first recorded in 1937. In 1984, prospector Richard Haslinger and BP Resources Canada Limited located claims on the site. In 1986, Lincoln Resources Inc. (“Lincoln”) optioned the claims and in 1987 completed a diamond drilling program that led to the discovery of significant copper-gold mineralization. In 1991, Placer Development Ltd. (which became Placer Dome Inc.) (“Placer”) acquired Lincoln’s interest in the Mount Milligan property, resumed exploration drilling, completed a pre-feasibility study and applied for provincial and federal approvals to develop the project. These approvals expired in 2003. Barrick Gold Corporation purchased Placer in 2006 and sold its Canadian assets to Goldcorp Inc., which then in turn sold its interest in Mount Milligan to Atlas Cromwell. Atlas Cromwell then changed its name to Terrane Metals Corp. In October 2010, we acquired Terrane and the Mount Milligan project.

Geology, Deposit Types and Mineralization

Mount Milligan Mine is a tabular, near-surface, alkalic copper-gold porphyry deposit that measures some 2.6 kilometers north-south, 1.6 kilometers east-west and is more than 396 meters thick. It consists of two principal deposits, the Main deposit and Southern Star deposit. The Main deposit includes four contiguous zones: MBX, WBX, DWBX and 66, all of which are spatially associated with the MBX monzonite stock and Rainbow Dyke. The Southern Star deposit is centered on a monzonite stock of the same name and is some 500 meters south of the Main deposit.

Mineralization consists primarily of chalcopyrite with lesser bornite and magnetite in areas of potassic alteration, and pyrite in areas of propylitic alteration. In the main deposit, mineralization is best developed in areas of potassic alteration, where copper and gold grades are related to chalcopyrite and pyrite. High gold values are found in each deposit, mostly associated with pyrite, but the highest gold grades are found in the 66 zone and are related mainly to pyrite mineralization.

Exploration

A 5,590-meter core drilling program was completed in 2011 to follow-up previous holes drilled into the footwall of the WBX and other stocks, where potential copper-gold mineralization was indicated at depth. A total of eight holes were drilled, testing primarily for down-faulted blocks of mineralized rock below the western portion of the current deposit and pit limits. An additional 867 meters of core was drilled in ten holes to provide new samples for metallurgical test work. There was no exploration activity at Mount Milligan in 2013. Exploration work was conducted in 2014 on the mining claims and consisted of soil sampling, geological mapping, ground geophysical surveying (induced Polarization and magnetics) along with detailed follow-up mapping.

In 2015, a 1,786 meter core drilling program was completed to follow-up coincident soil geochemical, IP, and magnetic anomalies targeted from previous exploration work northwest of the main WBX deposit. A total of five holes were drilled. In 2016, a 2,500 meter, six hole continuation drill program is being planned.

THOMPSON CREEK MINE (Molybdenum)

General

TC Mine is an open-pit molybdenum mine and concentrator located approximately 48 kilometers southwest of the town of Challis, Idaho, USA.

The TC Mine land holdings comprise of 1,589 patented and unpatented lode, mill site and placer claims along with fee owned property totaling approximately 9,955 hectares. All current resources are located on patented mineral claims and are not expected to be subject to any US federal government royalties that could be enacted in the future. Approximately 50% of the mineral claims are located within the boundaries of the Salmon-Challis National Forest, with the remaining 50% located within the perimeter of land managed by the United States Bureau of Land Management. Annual assessment fees, totaling $170,035 were made to the United States Bureau of Land Management in 2015 to maintain 1,097 unpatented mining claims at TC Mine through August 2016. We also paid state and county property taxes of $781,268 in 2015.

Due to declines in molybdenum prices and projected operating costs at TC Mine, in October 2012, we suspended waste stripping activity associated with Phase 8. Since that time, the molybdenum market has continued to weaken and, as a result, we put TC Mine on care and maintenance in December 2014 when the mining and processing of Phase 7 ore was completed. During the first seven months of 2015, we conducted limited stripping of waste at the mine for the next phase of mining; however, due to the continued weakness in the molybdenum market, we stopped the stripping project in early August 2015.

History

The TC Mine deposit was discovered in 1968 by Cyprus Mines Corporation (“Cyprus”). Surface exploration, diamond and reverse circulation drilling were done by Cyprus. Cyprus started construction of the mine in 1981, with full production beginning in 1983 and continuing until 1992 when operations were suspended due to depressed molybdenum prices. In 1993, Thompson Creek Metals Company USA, whom we acquired in October 2006, purchased the mine and resumed operations in 1994. The mine operated continuously from 1994 until it was placed on care and maintenance in December 2014; however, production was reduced during 2008 and 2009 due to reduced demand for molybdenum during that period.

Geology, Deposit Types and Mineralization

The TC Mine porphyry molybdenum deposit is located near the structural intersection of two geologic provinces: continental, arc-related intrusive rocks of the late Cretaceous Idaho Batholith (the “Idaho Batholith”) are exposed to the west of the mine, while complexly deformed Paleozoic metasedimentary rocks are dominant to the east. The Idaho Batholith is a multi-phase, long-lived intrusion with a granitic to granodioritic composition. Paleozoic metasedimentary rocks form the wall-rock portions of the TC Mine deposit. Historic mining within the district was associated with syngenetic stratiform base-, precious-metal (i.e. lead-silver) mineralization which is locally developed in the Paleozoic units. The majority of the TC Mine molybdenum deposit is hosted within igneous rocks of the TC Mine intrusive complex, with minor amounts found within adjacent metasediments.

The TC Mine deposit is classified as an intrusive-hosted molybdenum porphyry system. Porphyry molybdenum deposits are divided into two subtypes: Climax-type and Quartz Monzonite (Endako)-type. TC Mine belongs to the Quartz Monzonite category. In contrast to the rift-related (extensional) Climax-type deposits, the Quartz Monzonite-type deposits are formed by subduction-related (compressional) processes. Molybdenum mineralization at TC Mine is primarily hosted in a composite granodiorite-quartz monzonite stock of Cretaceous age (i.e. TC Mine intrusive complex). This composite stock intruded carbonaceous and locally limy argillite (i.e. metasediments) of the Mississippian Copper Basin Formation. Where it is in contact with the TC Mine intrusive complex, the argillite has been contact-metamorphosed to hornfels and locally to skarn. The intrusive and sedimentary rocks are unconformably overlain by the Eocene Challis Volcanics, a post-mineral sequence of andesite to rhyodacite tuffs, flows and agglomerates. Locally, the volcanic cover is up to 305 meters thick. These volcanic rocks fill valleys and depressions in the paleotopography around the TC Mine site.

Exploration

There were no exploration activities performed on-site or off-site in 2015 or 2014. We voluntarily forfeited our claims related to Long Canyon and Little Fall Creek in 2015. 2013 exploration activities around and peripheral to the TC Mine infrastructure consisted of surface mapping and rock sampling. During 2013, a drilling permit was approved by the United States Forest Service for exploration drilling of targets identified within the Bruno Creek drainage east of the current mine infrastructure.

We do not anticipate any on-site or off-site exploration activities in the TC Mine area in 2016.

ENDAKO MINE (Molybdenum)

General

Endako Mine is an open-pit molybdenum mine, concentrator and roaster located approximately 161 kilometers west of Prince George, British Columbia, Canada.

Table of Contents

Endako Mine is accessible by commercial air carrier to Prince George, British Columbia, then by vehicle west on a paved highway for approximately 161 kilometers, then south on the Endako Mine road for an additional 11 kilometers. In March 2012, we completed a mill expansion project at Endako Mine. The expansion project included the construction of a new mill to replace the previous mill constructed in the 1960’s. The new mill is designed to process 55,000 tons of ore per day compared to 31,000 tons per day in the old mill. The previous 45-year old mill at the site has been shut down and is currently on care and maintenance.

Endako Mine is operated as a joint venture (the “Endako Mine Joint Venture”) between Thompson Creek Mining Ltd. (“TCML”), one of our subsidiaries, which holds a 75% interest, and Sojitz Moly Resources, Inc. (“Sojitz”), a subsidiary of Sojitz Corporation, which holds the remaining 25% interest. See “Endako Mine Joint Venture” below for further details regarding the Endako Mine Joint Venture.

The property currently comprises a contiguous group of 59 mineral tenures containing 33 claims and 26 leases, covering approximately 12,797 hectares. In addition, the Endako Mine Joint Venture holds surface rights to a portion of the mine site area. The mineral leases are subject to annual fees, and the mineral claims are subject to exploration expenditure obligations. We may choose to pay annual fees to the Province in lieu of exploration expenditures. All mineral claims are in good standing, and expiry dates range from October 2016 to February 2024. We expect to renew such mineral claims in the ordinary course.

Endako Mine deposit is divided into four named areas: Northwest, Denak West, Denak East and Endako. Mining is in progress or has occurred in the Endako and both Denak areas. The Northwest zone is yet to be put in operation. There are no royalties, back-in rights, encumbrances on title or other agreements, other than the agreement governing the Endako Mine Joint Venture. The infrastructure at Endako Mine includes a 55,000 ton per day concentrator, a 35,000 to 40,000 pound per day roaster (and an additional non-operating roaster), tailings and reclaim water ponds, a crushing plant, waste rock dumps, an administrative building, a truck shop/warehouse, a change house, a first aid station, a laboratory, a garage and other shops. The power supply of the site is provided by a 9 kilometer, 69 kV power line owned by B.C. Hydro from a nearby substation. Water for the milling process is re-circulated from the tailings facility while make-up water is pumped from François Lake, located nearby.

In mid-December 2014, we announced that Sojitz had agreed with us to place Endako Mine on temporary suspension effective December 31, 2014, due to continued weakness in the molybdenum market. In connection with the temporary suspension, approximately 50% of salaried employees at Endako Mine were terminated by December 31, 2014, and the employment of the hourly employees was temporarily suspended after the required 60-day notice period through to the placement of Endako on care and maintenance effective July 1, 2015. As of December 31, 2015, approximately 11 employees remain at Endako Mine for care and maintenance activities.

History

The Endako Mine deposit was discovered in 1927 by local hunters. Minor underground exploration work took place in subsequent years. In 1962, R&P Metals Corporation Ltd. began a diamond drilling program to evaluate the discovery and, based on the exploration results, incorporated a company named Endako Mines Ltd. Canadian Exploration Limited, a wholly owned subsidiary of Placer, entered into an option agreement with Endako Mines Ltd. in August 1962 and continued exploration on the property.

In March 1964, Placer decided to place the property into production. Production commenced in June 1965 at a plant capacity of approximately 10,000 tons per day (combined concentrator and roaster). Expansions in 1967 and improvements in 1980 increased the concentrator capacity. In 1982, the mine and concentrator were closed due to low molybdenum prices, but the roaster continued to operate, processing molybdenum concentrates from other operations on a toll basis.

The mine and mill were re-opened in 1986, and by 1989 production reached approximately 31,000 tons per day. In June 1997, TCML and Sojitz, the parties to the Endako Mine Joint Venture, purchased Endako Mine from Placer. We acquired TCML in October 2006 through our acquisition of Thompson Creek Metals Company USA.

Geology, Deposit Types and Mineralization

The Endako Mine deposit is located within the intermontane morphology/tectonic belt of British Columbia, Canada. The Endako Mine molybdenite deposit is hosted in the Endako quartz monzonite intrusive, a phase of the middle to late Jurassic François Lake Intrusions that form a large composite batholith. The deposit is genetically associated with the terminal stages of magmatic activity, represented by intrusion of the Casey monzogranite.

Table of Contents

Molybdenite is the primary metallic mineral on the Endako Mine property. Minor pyrite, magnetite and chalcopyrite and traces of sphalerite, bornite, specularite and scheelite are also present. Single occurrences of beryl and bismuthinite have been reported. Molybdenite occurs in two types of veins. Large veins (up to 1.2 meters wide) contain laminae and fine disseminations of molybdenite. The second vein type occurs as stockworks adjacent to the major veins in the form of fine fracture-fillings and veinlets of quartz-molybdenite. Pyrite is most abundant along the southern margin of the zone of molybdenum mineralization.

Exploration

No exploration activities were completed in 2015. Pit designs for the newest operational area, the Denak West Extension are ready, however, the mine went into care and maintenance prior to breaking new ground, (June 1, 2015). A new one unit claim will require a minor soil sampling program in 2016 to maintain title.

Endako Mine Joint Venture

The Endako Mine Joint Venture was formed on June 12, 1997 pursuant to the terms of the Exploration, Development and Mine Operating Agreement between TCML and Sojitz (the “Endako Mine Joint Venture Agreement”). We were appointed manager of the Endako Mine Joint Venture with overall management responsibility for operations. As manager, we prepare annual budgets and production plans and submit them to Sojitz for approval. In the event Sojitz rejects any or all of a proposed budget or production plan, the parties are required to work to develop a mutually acceptable budget and production plan. As manager, we manage, direct and control Endako Mine, provided that each of the following actions requires the approval of both us and Sojitz: (i) disposition of all or a substantial portion of the Endako Mine assets; (ii) contracts with affiliates over $500,000 or sales of product to our affiliates or affiliates of Sojitz; (iii) compensation for management of the business; (iv) modification of the Endako Mine Joint Venture Agreement; (v) any change in business purpose; (vi) any modifications or replacements to the production plan for Endako Mine; (vii) investment in other companies; (viii) any borrowing by the joint venture or loan to any third party or any guarantee; (ix) changes in the manager, other than by reasons of default; and (x) except in the case of emergency or unexpected expenditures, a discretionary capital expenditure in excess of $1.0 million. Our and Sojitz’s participating interests in the joint venture are currently 75% and 25%, respectively; those interests may be recalculated under certain circumstances set forth in the Endako Mine Joint Venture Agreement.

OTHER OPERATING PROPERTIES

Langeloth Metallurgical Facility

Our wholly-owned Langeloth Facility is located in Langeloth, Pennsylvania, approximately 40 kilometers west of Pittsburgh, on land we own in fee simple. The facility receives molybdenum concentrate from third party producers that is either purchased for processing and re-sale or that is toll converted to finished products for third parties. The facility produces and sells ammonium perrhenate and rhenium metal pellets as well as sulfuric acid all recovered as by-products of processing the molybdenum disulfide. In addition, the Langeloth Facility calcines other metal containing materials from various third-party operations.

Four multiple-hearth furnaces are used for the conversion (roasting) of molybdenum concentrate into technical grade molybdenum oxide. These four roasters have the annual capacity to process 36 million pounds of molybdenum contained in concentrates. The molybdenum oxide can be sold as a finished product to customers or can be upgraded at the facility to molybdenum oxide briquettes, pure molybdenum trioxide powder or various sizes of ferromolybdenum products. Two furnaces are used to calcine non-hazardous metal containing materials that contain metals other than molybdenum.

The plant has been and continues to be upgraded by an ongoing capital improvement program. Further, an acid plant shutdown occurs approximately every three years to refurbish acid plant process equipment. A five-week shutdown occurred in the third quarter of 2015.

EXPLORATION PROPERTIES

Berg Property

In October 2010, we acquired the Berg property as part of the Terrane acquisition. The Berg property is a copper, molybdenum and silver exploration property that is located in the Omineca Mining Division within the Tahtsa Ranges of west-central British Columbia, Canada approximately 84 kilometers southwest of Houston and 23 kilometers northwest of the Huckleberry Mine. The Berg property comprises 115 mineral claims and one mining lease centered at 53° 48’ North Latitude and 127° 26’ West Longitude for a total of approximately 45,949 acres.

Table of Contents

The Berg property is 100% owned by us with a 1% net smelter return royalty held by Royal Gold on eight of the mineral claims and one mining lease, including those which host the deposit on the Berg property. All mineral claims and the mining lease are in good standing and good to dates ranging from August 2016 to November 2021. Mineral claims are subject to exploration expenditure obligations, or we may choose to pay annual fees to the province in lieu of exploration expenditures. We expect to renew such mineral claims and mining lease in the ordinary course.

Drilling on the property was initiated by Kennecott in 1965, and this led to the delineation of two main mineralized zones. In 1972, exploration and development of the Berg property were taken over by another owner under agreement with Kennecott, and by 1980, a total of 119 diamond drill holes for 20,128 meters had been completed on the Berg property. In 2007 and 2008, Terrane carried out diamond drill programs totaling 22,948 meters in 60 holes designed to confirm the results of previous work and define the resource with infill and step-out drilling, particularly below the historic resource, and provide fresh material for metallurgical test work. In 2011, we commissioned additional exploration and drilling delineation to support an advanced scoping study. The 2011 drilling program included 10,678 meters of drilling (35,024 feet). In 2014 and 2015, helicopter-supported surface mapping and sampling programs were performed over the Berg property and the environmental baseline monitoring programs were maintained. The 2015 program collected and reported on 92 rock, 46 stream silt and 1,763 soil samples. A 2016 program, including soil sampling, is planned to further sample previously identified anomalies and locate drill targets for 2017.

Maze Lake Property

In 2015, we terminated the Mineral Exploration Agreements with respect to the Maze Lake prospect. As of December 31, 2015, we have no further commitments or obligations with regard to the Maze Lake prospect.

IKE Project

In the third quarter of 2015, we funded C$3.0 million for exploration work conducted by Amarc Resources Ltd. (“Amarc”) in the IKE copper-molybdenum-silver porphyry deposit in south-central British Columbia (“IKE” or the “IKE Project”). As of the date of this report, we are finalizing an agreement with Amarc pursuant to which we would have the option to acquire, through a staged investment process, a 30% ownership interest in the IKE Project. After acquiring a 30% interest, we have an option to acquire an additional 20% interest in the IKE, subject to certain conditions, including the completion of a feasibility study. The C$3.0 million funded in 2015 counts towards the 30% ownership earn-in.

MINERAL RESERVES

Our proven and probable mineral reserves have been estimated in accordance with the definitions of such terms adopted by the Canadian Institute of Mining, Metallurgy and Petroleum, ("CIM") and incorporated in NI 43-101 by Canadian securities regulatory authorities. A technical report has been filed regarding the disclosure of mineral reserves for our material property, Mount Milligan Mine, as required by NI 43-101. The proven and probable estimated mineral reserves are those tonnages contained within economically optimized pits, configured using current and predicted mining and processing methods and related operating costs and performance parameters. Mineral reserve estimates reflect our reasonable expectation that all necessary permits and approvals will be obtained and maintained. We believe that our proven and probable estimated mineral reserves are equivalent to proven and probable reserves as defined by the Securities and Exchange Commission's (the "SEC") Industry Guide 7. See the Glossary of Terms below for an explanation of mining terms used in this report.

The estimation of mineral reserves is constrained to an economically optimized pit based on all operating costs, including the costs to mine. Since all material lying within the optimized pit will be mined, the cut-off grade used in determining mineral reserves is estimated based on the material that, having been mined, is economic to transport and process without regard to primary mining costs (i.e., mining costs that were appropriately applied at the economic optimization stage).

The QA/QC controls program used in connection with the estimation of our mineral reserves consists of regular insertion and analysis of blanks and standards to monitor laboratory performance.

The mineral reserve estimates for Mount Milligan Mine were prepared by Robert Clifford, our Director of Mine Engineering, who is a Qualified Person under NI 43-101. The mineral reserve estimates were prepared using an ultimate open pit design optimized at spot metal prices of $2.95/lb copper, $1,250/oz gold, an exchange rate of US$1.00/C$1.10, a cut-off grade of 0.176% copper equivalent and takes into consideration metallurgical recoveries, concentrate grades, transportation costs, smelter treatment charges and royalty and streaming arrangements in determining economic viability. The mineral reserve estimates are based on the cost assumptions included in the NI 43-101 technical report entitled "NI 43-101 Technical Report-Mount Milligan Mine-Northern Central British Columbia" dated January 21, 2015 and filed on SEDAR on January 21, 2015. Mill recoveries vary by rock type and region but average 85.0% copper and 71.5% gold. Anticipated losses resulting from beneficiation average approximately 4.5% copper and 2.5% gold.

TC Mine and Endako Mine Mineral Reserves

There are no mineral reserves to report for either the TC Mine or the Endako Mine for the year ended December 31, 2015. Our review indicated that the mineral reserves at the TC Mine and the Endako Mine were no longer viable (at prices and exchange rates discussed below), and as such, we re-classified them as mineral resources in the 2015 mineral resources statement reported herein.

Reconciliation of Estimated Mineral Reserves Under NI 43-101 and Under SEC Industry Guide 7

As mineral reserves are reported under both NI 43-101 and SEC Industry Guide 7 standards, it is possible for mineral reserve figures to vary between the two standards due to the differences in reporting requirements under each standard. For example, the definitions adopted by the CIM and incorporated in NI 43-101 have a minimum requirement that mineral reserves be supported by a pre-feasibility study, whereas SEC Industry Guide 7 requires support from a detailed feasibility study that demonstrates that economic extraction is justified. For our estimated mineral reserves at December 31, 2015, there is no difference between the mineral reserves as disclosed under NI 43-101 and those disclosed under SEC Industry Guide 7, and therefore no reconciliation is provided.

NON-RESERVES—ESTIMATED MEASURED AND INDICATED MINERAL RESOURCES

Cautionary note to US investors concerning estimates of measured and indicated mineral resources

This section uses the terms "measured mineral resources" and "indicated mineral resources." We advise US investors that, while those terms are recognized and required by Canadian regulations, the SEC does not recognize them. US investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into mineral reserves.

The estimated measured and indicated mineral resources which are reported herein do not include that part of our mineral resources that have been converted to proven and probable mineral reserves as shown above. Measured and indicated mineral resources have been estimated in accordance with the definitions of such terms adopted by the CIM and incorporated in NI 43-101. We have filed a technical report regarding the disclosure of mineral resources for our material property, Mount Milligan Mine. Measured and indicated mineral resources are equivalent to mineralized material as such term is defined in SEC Industry Guide 7. See the Glossary of Terms below for an explanation of mining terms used in this report.

The total estimated measured and indicated mineral resources for all properties have been estimated at variable economic cut-off grades based on the metal prices provided below, and on economic parameters deemed realistic. The economic cut-off grades for mineral resources are lower than those for mineral reserves and are indicative of the fact that the mineral resource estimates include material that may become economic under more favorable conditions, including increases in metal prices.

The mineral resource estimates utilized a cut-off grade of 0.030% Mo and an average long-term molybdenum price of $10.00 per pound. The mineral reserves previously reported proved to be uneconomic and have been re-allocated back as mineral resources and reported in the tables above.

NON-RESERVES—ESTIMATED INFERRED MINERAL RESOURCES

Cautionary note to US investors concerning estimates of inferred mineral resources

This section uses the term "inferred mineral resources." We advise US investors that while this term is recognized and required by Canadian regulations, the SEC does not recognize it. "Inferred mineral resources" have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of inferred mineral resources will ever be converted into mineral reserves. In accordance with Canadian rules, estimates of inferred mineral resources cannot form the basis of feasibility or other economic studies. US investors are cautioned not to assume that part or all of the inferred mineral resources exists, or is economically or legally mineable.

Inferred mineral resources have been estimated in accordance with the definitions of such terms adopted by the CIM and incorporated in NI 43-101. We have filed technical reports regarding the disclosure of mineral resources for TC Mine and Endako Mine, Mount Milligan, and the Berg property. See the Glossary of Terms below for an explanation of mining terms used in this report.

The following tables summarize estimated non-reserves—inferred mineral resources as of December 31, 2015:

GLOSSARY OF TERMS

SEC Industry Guide 7 Definitions



reserve		The term "reserve" refers to that part of a mineral deposit which could be economically and legally extracted or produced at the time of the reserve determination. Reserves must be supported by a feasibility⁽¹⁾ study done to bankable standards that demonstrates the economic extraction. ("Bankable standards" implies that the confidence attached to the costs and achievements developed in the study is sufficient for the project to be eligible for external debt financing.) A reserve includes adjustments to the in-situ tonnes and grade to include diluting materials and allowances for losses that might occur when the material is mined.
proven reserve		The term "proven reserve" refers to reserves for which (a) quantity is computed from dimensions revealed in outcrops, trenches, workings or drill holes; grade and/or quality are computed from the results of detailed sampling and (b) the sites for inspection, sampling and measurement are spaced so closely and the geologic character is so well defined that size, shape depth and mineral content of reserves are well-established.
probable reserve		The term "probable reserve" refers to reserves for which quantity and grade and/or quality are computed from information similar to that used for proven (measured) reserves, but the sites for inspection, sampling and measurement are farther apart or are otherwise less adequately spaced. The degree of assurance, although lower than that for proven reserves, is high enough to assume continuity between points of observation.
mineralized material ⁽²⁾		The term "mineralized material" refers to material that is not included in the reserve as it does not meet all of the criteria for adequate demonstration for economic or legal extraction.
non-reserves		The term "non-reserves" refers to mineralized material that is not included in the reserve as it does not meet all of the criteria for adequate demonstration for economic or legal extraction.

_______________________________________________________________________________


⁽¹⁾	For SEC Industry Guide 7 purposes, the feasibility study must include adequate information on mining, processing, metallurgical, economic and other relevant factors that demonstrate, at the time of reporting, that economic extraction is justified.


⁽²⁾	This category is substantially equivalent to the combined categories of measured mineral resource and indicated mineral resource specified in NI 43-101.

Table of Contents

NI 43-101 Definitions



mineral reserve		The term "mineral reserve" refers to the economically mineable part of a measured and/or indicated mineral resource. It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies at pre-feasibility or feasibility level as appropriate that include application of “modifying factors”. Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified. The reference point at which mineral reserves are defined, usually the point where the ore is delivered to the processing plant, must be stated. It is important that, in all situations where the reference point is different, such as for a saleable product, a clarifying statement is included to ensure that the reader is fully informed as to what is being reported. The public disclosure of a mineral reserve must be demonstrated by a pre-feasibility study or feasibility study.
proven mineral reserve		The term "proven mineral reserve" refers to the economically mineable part of a measured mineral resource. A proven mineral reserve implies a high degree of confidence in the “modifying factors”.
probable mineral reserve		The term "probable mineral reserve" refers to the economically mineable part of an indicated, and in some circumstances, a measured mineral resource. The confidence in the “modifying factors” applying to a probable mineral reserve is lower than that applying to a proven mineral reserve.
modifying factors		The term “modifying factors” refers to considerations used to convert mineral resources to mineral reserves. These include, but are not restricted to, mining, processing, metallurgical, infrastructure, economic, marketing, legal, environmental, social and governmental factors.
mineral resource		The term "mineral resource" refers to a concentration or occurrence of solid material of economic interest in or on the Earth’s crust in such form, grade or quality and quantity that there are reasonable prospects for economic extraction. The location, quantity, grade or quality, continuity and other geological characteristics of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge, including sampling. Mineral resources are sub-divided, in order of increasing geological confidence, into inferred, indicated and measured categories.
measured mineral resource		The term "measured mineral resource" refers to that part of a mineral resource for which quantity, grade or quality, densities, shape, and physical characteristics are estimated with confidence sufficient to allow the application of “modifying factors” to support detailed mine planning and final evaluation of the economic viability of the deposit. Geological evidence is derived from detailed and reliable exploration, sampling and testing and is sufficient to confirm geological and grade or quality continuity between points of observation. A measured mineral resource has a higher level of confidence than that applying to either an indicated mineral resource or an inferred mineral resource. It may be converted to a proven mineral reserve or to a probable mineral reserve.

Table of Contents



indicated mineral resource		The term "indicated mineral resource" refers to that part of a mineral resource for which quantity, grade or quality, densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of “modifying factors” in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing and is sufficient to assume geological and grade or quality continuity between points of observation. An indicated mineral resource has a lower level of confidence than that applying to a measured mineral resource and may only be converted to a probable mineral reserve.
inferred mineral resource		The term "inferred mineral resource" refers to that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity. An inferred mineral resource has a lower level of confidence than that applying to an indicated mineral resource and must not be converted to a mineral reserve. It is reasonably expected that the majority of inferred mineral resources could be upgraded to indicated mineral resources with continued exploration.
Qualified Person ⁽¹⁾		The term "Qualified Person" means an individual who (a) is an engineer or geoscientist with a university degree, or equivalent accreditation, in an area of geoscience, or engineering, relating to mineral exploration or mining; (b) has at least five years of experience in mineral exploration, mine development or operation or mineral project assessment, or any combination of these, that is relevant to his or her professional degree or area of practice; (c) has experience relevant to the subject matter of the mineral project and the technical report; (d) is in good standing with a professional association; and (e) in the case of a professional association in a foreign jurisdiction, has a membership designation that (i) requires attainment of a position of responsibility in their profession that requires the exercise of independent judgment; and (ii) requires a favorable confidential peer evaluation of the individual’s character, professional judgment, experience, and ethical fitness; or a recommendation for membership by at least two peers, and demonstrated prominence or expertise in the field of mineral exploration or mining.

ITEM 1A. RISK FACTORS

Our operations and financial results are subject to various risks and uncertainties, including those described below, that could materially adversely affect our business, financial condition, results of operations, cash flows and the trading price of our common stock. Such risks are not the only ones we face and additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business.

Financial Risks

Extended declines in the prices of copper and gold would have a material adverse effect on our earnings and cash flows and our ability to repay our outstanding debt as it comes due. Fluctuations in the prices of copper and gold can cause significant volatility in our financial performance and materially and adversely affect the trading prices of our debt and common stock.

Our core business is dependent on the prices of copper and gold, which are volatile and are affected by numerous factors beyond our control. Our ability to recommence operations at our molybdenum mines depend on the price of molybdenum, which has declined in recent years. Factors tending to influence such metals prices include the following:


•	the rates of global economic growth;


•	worldwide demand for products containing copper, gold and molybdenum ;


•	worldwide supply of these metals including the expected near-term supply from new mine sources ;


•	the availability and cost of substitute materials;


•	inventory levels;


•	the industry production cost curve and the expected cost to develop new sources of supply;


•	expectations with respect to the rate of inflation;


•	the relative strength of the US dollar and certain other currencies;

Table of Contents


•	interest rates;


•	global or regional political or economic conditions, including interest rates and currency values; and


•	sales by central banks and other holders, speculators and producers in response to any of the above factors.

The prices of copper, gold and molybdenum have fluctuated historically. During the three years ended December 31, 2015, the average daily spot copper price on the London Metals Exchange ranged from a low of $2.05 to a high of $3.74 per pound, and the average daily London P.M. fixed prices for gold per ounce on the London Bullion Market ranged from a low of $1,049 to a high of $1,694. The average daily price for molybdenum quoted in Platts Metals Week ranged from a low of $4.30 to a high of $15.05 per pound during the three years ended December 31, 2015. There is no assurance that any hedging transactions designed to reduce the risk associated with fluctuations in metal prices will be successful.

Any decline in the prices of copper or gold adversely impacts our revenues, net income, cash flows, and credit quality and could affect our ability to make necessary capital investments, repay our debt and meet our debt service and other fixed obligations, and depress the trading prices of our common stock and our publicly traded debt securities. Sustained declines in prices could also:


•	cause us to revise our operating plans, resulting in reduced output, the placement of our copper-gold mine on care and maintenance or closure of one or more of our mines or other facilities;


•	further reduce revenues through production declines due to cessation of mining of deposits that have become uneconomic;


•	reduce funds available for capital expenditures;


•	delay or prevent our ability to make accretive acquisitions or conduct exploration work;


•	reduce existing reserves due to economic viability; and


•	cause us to write down assets and accelerate depletion, reclamation and closure charges.

Our substantial indebtedness could adversely affect our business, results of operations or financial condition.

As of December 31, 2015, our total debt was approximately $884.6 million, including equipment lease obligations. We also had $724.8 million in deferred revenue under the Gold Stream Arrangement as of December 31, 2015. Until the deposits received in the Gold Stream Arrangement have been fully offset against Royal Gold’s purchases of gold under the Gold Stream Arrangement, the deposits will be secured by our Mount Milligan Mine assets. After the deposits have been fully offset, Royal Gold will continue to have a security interest in 52.25% of the refined gold produced from Mount Milligan Mine.

We currently have three series of senior notes, with an aggregate principal amount of approximately $833 million, outstanding as of December 31, 2015. Approximately $316 million principal amount of senior secured notes mature in December 2017 (the “2017 Notes”), approximately $334 million principal amount of senior unsecured notes mature in June 2018 (the “2018 Notes”), and approximately $183 million principal amount of senior unsecured notes mature in May 2019 (the “2019 Notes” and, together with the 2017 Notes and the 2018 Notes, the “Senior Notes”)).

Subject to the limits contained in the indentures that govern our outstanding 2017 Notes, 2018 Notes and 2019 Notes, the Gold Stream Arrangement, and our other debt instruments, we may be able to incur additional debt. If we do so, the risks related to our high level of debt could intensify. Specifically, our high level of debt could have important negative consequences, including:


•	making it difficult for us to satisfy our obligations with respect to our debt and increasing the risk that we default on our debt obligations;


•	limiting our ability to obtain additional financing to fund future working capital, capital expenditures, acquisitions or other general corporate requirements;


•	requiring a substantial portion of our cash flows to be dedicated to debt service payments instead of other purposes, thereby reducing the amount of cash flows available for working capital, capital expenditures, acquisitions, financial assurances and other general corporate purposes;


•	increasing our vulnerability to declines in the prices of our commodities and general adverse economic and industry conditions;

Table of Contents


•	limiting our flexibility in planning for and reacting to changes in the industry in which we compete;


•	limiting management's discretion in operating our business;


•	placing us at a disadvantage compared to other, less leveraged competitors;


•	increasing our cost of borrowing; and


•	limiting our ability to pursue certain types of strategic opportunities.

We may be unable to generate sufficient cash to repay our outstanding Senior Notes upon their maturity, and, as we approach the maturity of such Senior Notes, we may have insufficient cash to meet our ongoing liquidity needs.

Our ability to repay our outstanding Senior Notes as they become due, make interest payments on our Senior Notes as they become due, or to restructure or refinance our outstanding Senior Notes and to fund our planned capital expenditures and other liquidity needs depend on our ability to generate sufficient cash flow from operations, which, as discussed above, is subject to multiple factors beyond our control, including prevailing economic conditions and commodity prices. There is no assurance that we will generate sufficient cash flow from operations to service our debt, repay our Senior Notes upon maturity, or fund our ongoing liquidity needs. If we are unable to generate sufficient cash flows to make payments on or refinance our debt or obtain new financing, we would have to consider other options, such as sales of assets, reduction or delay of capital expenditures, sales of equity, negotiations with our lenders to restructure or refinance the applicable debt or commencement of voluntary reorganization, bankruptcy or insolvency proceedings. We may not be able to effect any such measures on commercially reasonable terms or at all and, even if successful, certain of these actions, including asset sales or refinancing, may not allow us to satisfy all of our debt obligations.

The indentures that govern the outstanding 2017 Notes, 2018 Notes and 2019 Notes and the Gold Stream Agreement contain covenants that restrict our current and future operations and limit our flexibility and ability to respond to changes or take certain actions.

The indentures that govern our outstanding 2017 Notes, 2018 Notes and 2019 Notes contain certain restrictive covenants that impose significant operating and financial restrictions on us and, in some circumstances, limit our ability to engage in actions that may be in our long-term best interest, including, among other things, our ability:


•	to incur additional debt;


•	to sell, lease or transfer our assets;


•	to pay dividends or make other distributions or repurchase or redeem capital stock;


•	to prepay, redeem or repurchase certain debt;


•	to make loans or investments;


•	to enter into agreements restricting our subsidiaries' ability to pay dividends;


•	to make capital expenditures and investments;


•	to guarantee debts or other obligations;


•	to create liens;


•	to enter into transactions with our affiliates; and


•	to enter into certain merger, consolidation or other reorganization transactions.

In addition, the Gold Stream Arrangement contains restrictions on our ability to incur additional secured debt.

These restrictions could limit our ability to restructure or refinance our outstanding Senior Notes, secure the needed working capital to withstand prolonged downturns in our industry or the economy in general or otherwise take advantage of business opportunities that may arise, any of which could place us at a disadvantage relative to our competitors that may have less debt and are not subject to such restrictions.

A default under any of our indebtedness arrangements could trigger cross defaults to our other agreements, which could have a material adverse effect on our financial condition.

A failure to satisfy any of our debt obligations could be exacerbated by cross default provisions. For example, a default under the Caterpillar equipment financing facility will trigger cross defaults to the Gold Stream Arrangement, and vice versa, and could also trigger cross defaults to the indentures governing our outstanding Senior Notes and other material agreements. In the event of a default under the Caterpillar equipment financing facility, Caterpillar could: (1) terminate the lease by us of equipment purchased by the lender and leased to us pursuant to the facility; (2) accelerate the payment of all lease payments unpaid under the facility, together with default interest; (3) accelerate the payment of the balance of the purchase price for equipment, which would have been due and payable from the date of termination; and (4) foreclose on the equipment purchased and leased under the facility and apply the proceeds from the sale of such equipment to any shortfall in the payment by us of amounts due. In the event of default under the Gold Stream Arrangement, Royal Gold could require us to repay the amounts Royal Gold has invested in Mount Milligan Mine, as adjusted and reflected in the deposit record maintained in accordance with the Gold Stream Arrangement, which amounts totaled $653.5 million as of December 31, 2015. In the event of a default under the indentures governing the 2017 Notes, 2018 Notes and 2019 Notes, the trustee or holders of at least 25% in principal of the outstanding 2017 Notes, 2018 Notes and 2019 Notes, as applicable, may declare the principal, premium, if any, and accrued and unpaid interest on the Senior Notes to be immediately due and payable. If we were to default under any of these arrangements, we may not have sufficient assets to repay such indebtedness or have access to sufficient alternative sources of funds. If we are unable to repay the indebtedness, the lenders, to the extent they hold assets as security for the obligations owed to them, could enforce against such assets, and we could be forced into reorganization, bankruptcy or insolvency proceedings.

We will likely need to restructure or refinance our outstanding Senior Notes before they mature. If our restructuring or refinancing plans are not successful, we will face significant liquidity challenges as we approach the maturity of our outstanding Senior Notes.

The significant decline in copper prices in 2015 and the continuing and expected weakness in the base metals market have materially impacted our ability to generate sufficient cash flow from operations to fully repay our outstanding Senior Notes when they come due, and, as a result, our credit quality has declined and our long-term liquidity has been adversely affected. Given current market conditions and commodity prices, we expect that we will need to refinance or restructure our outstanding Senior Notes on or prior to their current maturities. As previously announced, we have engaged financial advisors to assist the Board of Directors in evaluating strategic and financial alternatives available to us, including debt refinancing and restructuring, new capital transactions, and asset sales. In connection with a restructuring or refinancing, we may seek to convert a significant portion of our outstanding debt to equity, including the exchange of debt for shares of our common stock. In addition, we may seek to reduce our cash interest cost and/or extend debt maturity dates by negotiating the exchange of outstanding debt for new debt with modified terms. While we anticipate engaging in active dialogue with our creditors, at this time, we are unable to predict the outcome of such discussions, the outcome of any strategic transactions that we may pursue or whether any such efforts will ultimately be successful. In addition, our ability to complete new capital transactions efficiently depends on a number of factors, including the state of global commodity, credit and equity markets, interest rates, credit spreads, and our credit ratings. If we are unable to refinance or restructure our outstanding Senior Notes, complete new capital transactions or obtain additional financings on acceptable terms or at all, we will face significant liquidity challenges as we approach the maturity of our outstanding Senior Notes, and we may ultimately be unable to continue as a going concern.

Our potential for restructuring transactions may impact our business, financial condition and operations.

Due to our need to restructure or refinance our debt and/or engage in other restructuring activities, there is risk that, among other things:


•	third parties lose confidence in our ability to execute on our business strategy;


•	it may become more difficult to attract, retain or replace key employees, and our employees could be distracted from performance of their duties or more easily attracted to other career opportunities;


•	we could lose some or a significant portion of our liquidity, as a result of, among other things, stricter credit terms from suppliers, the commencement of reorganization, bankruptcy or insolvency proceedings or the inability to provide adequate protection to our secured lenders to permit us to access some or all of our cash; and


•	our suppliers, vendors and service providers and applicable regulatory authorities could seek to renegotiate the terms of our arrangements, terminate their relationship with us or require financial assurances from us.

Table of Contents

The occurrence of certain of these events may have a material adverse effect on our business, results of operations and financial condition. For example, as of December 31, 2015, we have provided the appropriate regulatory authorities in the US and Canada with approximately $73 million in reclamation financial assurance in the form of surety bonds for our share of mine closure obligations in the various jurisdictions in which we operate. As of December 31, 2015, the surety bonds required cash collateral of $10 million. Any perceived challenges to our liquidity in the short or long term could cause regulatory authorities to change the terms of our required bonding for our mine closure obligations and could cause our surety bond holders to increase the amount of cash collateral required or refuse to provide the same level of surety bonding, which could significantly increase our costs and decrease our liquidity. To the extent that the value of any security provided to regulatory authorities is or becomes insufficient to cover the amount of financial assurance we are required to post, we would be required to replace or supplement the existing security with more expensive forms of security, which might include cash deposits, which would have an adverse effect on our liquidity. There can be no assurance that we will be able to maintain or add to our current level of financial assurance. In addition, failure to provide regulatory authorities with the required financial assurances could potentially result in the closure of one or more of our operations.

An extended decline in metals prices, an increase in operating or capital costs, or a reduction in mineral reserve estimates, among other things, may cause us to record additional write downs, which could negatively impact our results of operations.

When events and circumstances indicate that the carrying amount of our long-lived assets may not be recoverable, we evaluate the recoverability of the carrying value by comparing it to the projected undiscounted cash flows from such asset or asset group. Under U.S. GAAP, the carrying value of a long-lived asset or asset group is considered impaired when the projected undiscounted cash flows from such asset or asset group is less than its carrying value. The economic environment, copper, gold and molybdenum prices, and our stock price may be considered as impairment indicators for the purposes of these impairment assessments. As disclosed in Item 7 of this Form 10-K, we recorded an aggregate of approximately $105 million in non-cash write downs of our exploration properties and our molybdenum fixed assets and materials and supplies inventory in 2014, primarily as a result of adverse conditions in the molybdenum market. While our 2015 impairment analysis did not result in any long-lived asset impairments, there can be no assurance that there will not be further asset impairments if commodity prices experience a sustained decline and/or if there are significant downward adjustments to estimates of recoverable quantities to be produced from estimated proven and probable mineral reserves or production quantities, upward adjustments to estimated operating costs and capital expenditures and/or changes in C$ to US$ foreign exchange rates, all based on life-of-mine plans and projections. Additional asset impairments would have an adverse impact on our results of operations and our ability to restructure/refinance our debt or obtain additional financing.

A lowering or withdrawal of the ratings assigned to our debt securities by rating agencies may increase our future borrowing costs and reduce our access to capital.

Our debt currently has a non-investment grade rating, and any rating assigned could be lowered or withdrawn entirely by a rating agency if, in that rating agency's judgment, future circumstances relating to the basis of the rating, such as adverse changes, so warrant. A potential or actual restructuring of our outstanding Senior Notes may be considered by the rating agencies as an adverse change warranting a downgrade of the rating of our debt securities. Any real or anticipated changes in our credit ratings will generally affect the market value of our outstanding debt securities. Any future lowering of our ratings would make it more difficult or more expensive for us to obtain additional debt financing and could lead our suppliers and other third parties with whom we do business to require us to provide financial assurance in the normal course of our operations.

Mine closure and reclamation costs for environmental liabilities may exceed the provisions we have made and our inability to provide reclamation bonding or maintain insurance could adversely affect our operating results and financial condition.

We are required by US federal and state laws and Canadian federal and provincial laws to provide financial assurance sufficient to allow a third party to implement approved closure and reclamation plans if we are unable to do so. These laws are complex and vary from jurisdiction to jurisdiction. The laws govern the determination of the scope and cost of the closure and reclamation obligations and the amount and forms of financial assurance. The amount and nature of the financial assurances are dependent upon a number of factors, including our financial condition and reclamation cost estimates.

As of December 31, 2015, we had provided the appropriate regulatory authorities in the United States and Canada with approximately $73 million in non-cash reclamation financial assurance in the form of surety bonds for our share of mine closure obligations in the various jurisdictions in which we operate. As of December 31, 2015, the surety bonds required cash collateral of approximately $10 million. As our operations expand or reclamation expenses increase, our reclamation obligations and the financial assurances that we are required to provide may increase accordingly. In addition, as discussed above, any perceived challenges to our liquidity may cause our surety bond holders to increase the amount of cash collateral required or refuse to provide the same level of surety bonding going forward. Increases in our reclamation obligations and financial assurances, as well as the nature of the security to be provided, could significantly increase our costs, making the

Table of Contents

maintenance and development of existing and new mines less economically feasible. To the extent that the value of the security provided to the regulatory authorities is or becomes insufficient to cover the amount of financial assurance we are required to post, we may be required to replace or supplement the existing security with more expensive forms of security, which might include cash deposits, which would reduce our cash available for operations and financing activities.

We have initiated discussions with relevant US federal and state agencies concerning additional bonding or funding of a trust agreement to cover long-term water treatment at TC Mine, although we are not currently under any requirement to do so. The amount of funding required is subject to numerous variables, potentially including an appropriate discount rate, and cannot be determined at this time. We may be required to engage in a similar discussion with provincial authorities in British Columbia with respect to the Endako Mine.

In addition, the costs of surety bonds and financial assurance have fluctuated in recent years while the market terms of such bonds and financial assurance have generally become less favorable to mine operators. These changes in the terms of the bonds and financial assurance have been accompanied at times by a decrease in the number of companies willing to issue surety bonds and financial assurance. Increased costs related to surety bonds and financial assurance, especially in connection with our current financial condition and restructuring efforts, could have a material adverse effect on our financial condition and liquidity.

There can be no assurance that we will be able to maintain or add to our current level of financial assurance. Failure to provide regulatory authorities with the required financial assurances could potentially result in the closure of one or more of our operations, which could result in a material adverse effect on our operating results and financial condition.

We are required, from time to time, to post financial assurances, and there can be no assurance that we will continue to be able to obtain financial assurances on acceptable terms.

In addition to our reclamation bonding obligations, we are from time to time required to post other financial assurance in the normal course of conducting our daily activities. This financial assurance can take several forms, including, but not limited to, letters of credit, performance bonds, deposits into escrow accounts for the benefit of the counterparty, trust funds or other funding mechanisms for long-term, post-reclamation obligations or the posting of cash collateral directly with the counterparty. In each case, the form of financial assurance to be provided is dictated by several factors, including expected length of time the financial assurance obligation is expected to remain outstanding, the amount of the obligation, the cost to us of providing the various forms of financial assurance and the creditworthiness of the counterparty. Our ability to obtain certain forms of financial assurance going forward will be impacted by our future financial performance and liquidity, changes to our credit rating and other factors that may be beyond our control. There can be no assurance that we will be able to obtain certain forms of financial assurance going forward or that we will be able to post cash collateral in lieu of being able to secure one of these other forms of financial assurance.

We enter into provisionally-priced sales contracts, which could have a negative impact on our revenues if prices decline.

We regularly enter into provisionally-priced sales contracts, whereby the contracts settle at prices to be determined at a future date. The future pricing mechanism of these agreements constitutes an embedded derivative, which is bifurcated and separately marked to estimated fair value at the end of each period. Changes to the fair value of embedded derivatives related to sales agreements are included in sales revenue in the determination of net income. To the extent final prices are higher or lower than what was recorded on a provisional basis, an increase or decrease to sales, respectively, is recorded each reporting period until the date of final pricing. Accordingly, in times of falling commodities prices, our revenues and cash flow are negatively impacted by lower prices received for contracts priced at current market rates and also from a decrease related to the final pricing of provisionally-priced sales pursuant to contracts entered into in prior years; in times of rising commodities prices, the opposite occurs.

Our operations are subject to currency fluctuations, which could adversely affect our results of operations and financial condition.

Exchange rate fluctuations may affect the costs that we incur in our operations. Our costs for Endako Mine and Mount Milligan Mine are incurred principally in Canadian dollars. However, our future revenue is tied primarily to market prices for copper and gold, which are denominated in US dollars. The appreciation of the Canadian dollar against the US dollar can increase the cost of our production and capital expenditures in US dollars, and our results of operations and financial condition could be materially adversely affected. Although we have in the past used, and may in the future use, hedging strategies to limit our exposure to currency fluctuations, there can be no assurance that such hedging strategies will be successful or that they will mitigate the risk of such fluctuations.

Table of Contents

We rely on a few key customers for our copper-gold concentrate from Mount Milligan Mine, and the loss of any one key customer could reduce our revenues.

We have entered into four multi-year concentrate sales agreements for the sale of copper-gold concentrate produced at Mount Milligan Mine. Pursuant to these agreements, we have agreed to sell an aggregate of approximately 120,000 tonnes in calendar year 2016, and 60,000 tonnes in 2017 and 40,000 tonnes in 2018. A breach of the applicable sales agreement by us or the applicable customer, a significant dispute with one of these customers, a force majeure event affecting the parties' respective performances under the agreement, a bankruptcy event experienced by the customer, early termination of the agreement, or any other event significantly and negatively impacting the contractual relationship with one of these customers could harm our financial condition. If, in such an event, we are unable to sell the affected concentrate volume to another customer, or we sell the affected concentrate to another customer on terms less advantageous terms to us, our revenues could be negatively impacted.

Our commodity hedging activities may reduce the realized prices we receive for our copper and gold, and involve market risk for the fair value of the derivatives, credit risk that our counterparties may be unable to satisfy their obligations to us, and financial risk due to fluctuations in the fair value of the derivatives.

In order to manage our cash flow exposure to copper and gold price volatility in selling production from Mount Milligan Mine, we enter into commodity derivatives from time to time for a portion of our expected production. Additionally, we receive cash provisional payments in selling production for Mount Milligan Mine, thus requiring that we purchase gold in order to satisfy our obligation to pay Royal Gold in gold. We enter into commodity derivatives from time to time in order to manage our gold price risk that arises when physical purchase and concentrate sales pricing periods do not match. We currently have in place unsecured hedging lines with various banks and trading companies in order to manage these exposures.

Commodity derivatives may limit the prices we actually realize and therefore could reduce our copper and gold revenues in the future. Our commodity hedging activities could impact our earnings in various ways, including recognition of certain mark-to-market gains and losses on derivative instruments. The fair value of our derivative instruments could fluctuate significantly between periods.

Our commodity derivatives may expose us to significant market risk, which is the risk that the fair value of a commodity derivative might be adversely affected by a change in underlying commodity prices or a change in our expected production, which may result in a significant financial loss on the derivative. We mitigate the potential market risk by establishing trading agreements with counterparties under which we are not required to post any collateral or make any margin calls on our derivatives. While our counterparties cannot require settlement solely because of an adverse change in the fair value of a derivative, due to our high debt credit profile and volatile commodity prices, our counterparties can decide to cease hedging activities with us. Further, we are also at risk of having a fewer number of counterparties available to enter into future hedging transactions. We mitigate the risk of having commodity derivative transactions in excess of our production by entering into derivatives for only a portion of our expected production. If we were to be forced into a reorganization, bankruptcy or insolvency proceeding, our hedging counterparties may be able to exercise remedies under the relevant derivatives agreement notwithstanding the filing of such proceeding and without seeking relief from the relevant court.

Our commodity derivatives also expose us to credit risk that counterparties may be unable to satisfy their obligations to us. We mitigate the potential credit risk by entering into derivatives with a number of counterparties, limiting the amount of exposure to any one counterparty, and monitoring the financial condition of the counterparties. However, given our current credit profile, we are at risk of having a limited number of counterparties available, which increases the potential credit risk of our commodity derivatives. If any of our counterparties were to default on its obligations to us under the derivative transaction or seek bankruptcy protection, it could result in a larger percentage of our future production being subject to commodity price changes which may have a significant adverse effect on our cash flow, our earnings and our financial condition. The risk of counterparty default is heightened in a poor economic environment.

The estimates contained in our production and cost guidance may not be achieved.

We provide estimates of future production, cash costs and capital costs for our operations, utilizing certain assumed Canadian dollar to U.S. dollar foreign exchange rates. No assurance can be given that such estimates will be achieved. Many of the factors described in this Item 1A may result in our failure to achieve our production estimates or materially increase our costs, either of which would have an adverse impact on our future cash flows, results of operations, and financial condition.

Operational Risks

Our business is subject to production and operational risks that could adversely affect our business and our insurance may not cover these risks and hazards adequately or at all.

Table of Contents

Mining and metals processing involve significant production and operational risks, some of which are outside of our control, including the following:


•	unanticipated ground and water conditions;


•	adverse claims to water rights and shortages of water to which we have rights;


•	adjacent or adverse land or mineral ownership that results in constraints on current or future mine operations;


•	geological problems, including earthquakes and other natural disasters;


•	metallurgical and other processing problems;


•	unusual or unexpected mineralogy or rock formations;


•	ground or slope failures;


•	tailings design or operational issues, including dam breaches or failures;


•	structural cave-ins, wall failures or rock-slides;


•	flooding or fires;


•	equipment failures;


•	periodic interruptions due to inclement or hazardous weather conditions or operating conditions and other force majeure events;


•	lower than expected ore grades or recovery rates;


•	accidents;


•	delays in the receipt of or failure to receive necessary government permits;


•	the results of litigation, including appeals of agency decisions;


•	delays in transportation;


•	interruption of energy supply;


•	labor disputes;


•	inability to obtain satisfactory insurance coverage;


•	the availability of drilling and related equipment in the area where mining operations will be conducted; and


•	the failure of equipment or processes to operate in accordance with specifications or expectations.

These risks could result in damage to, or destruction of, our mines, mills and roasting facilities, resulting in partial or complete shutdowns, personal injury or death, environmental or other damage to our properties or the properties of others, delays in mining, reduced production, monetary losses and potential legal liability. Milling operations are subject to hazards, such as equipment failure or failure of retaining dams around tailings disposal areas that may result in personal injury or death, environmental pollution and consequential liabilities.

In addition, we rely on a few key vendors for the transportation of concentrate from Mount Milligan Mine to our customers. Concentrate is transported from the mine site to Mackenzie, British Columbia, Canada by truck pursuant to a contract with a single trucking company, then to Vancouver by rail pursuant to a contract with a single railway operator, stored at the Port of Vancouver pursuant to a contract with the Port of Vancouver terminal operator, and shipped to our customers pursuant to a contract with a single shipping provider. A breach of the applicable contract by any of these vendors, a significant dispute with any of these vendors, a force majeure event or other operational or financial issues affecting one or more of these vendors, including labor strikes or work stoppages, or any other event that would significantly impede the ability of these vendors to perform their contractual obligations to us or that would have a significant negative impact on our contractual relationship with them would adversely affect our ability to satisfy our obligations to our customers, which could have a material impact on our financial condition and results of operations.

Table of Contents

Our insurance will not cover all the potential risks associated with our operations. In addition, although certain risks are insurable, we may be unable to maintain insurance to cover these risks at economically feasible premiums. Moreover, insurance against risks such as environmental pollution or other hazards as a result of exploration and production is not generally available to us or to other companies in the mining industry on acceptable terms. We might also become subject to liability for pollution or other hazards that may not be insured against or that we may elect not to insure against because of premium costs or other reasons. Losses from these events may cause us to incur significant costs that could have a material adverse effect upon our business. Furthermore, should we be unable to fund fully the cost of remedying an environmental problem, we might be required to suspend operations or enter into interim compliance measures pending completion of the required remedy.

Increased operating costs could affect our profitability.

Costs at any particular mining location are subject to variation due to a number of factors, such as changing ore grade, changing metallurgy and revisions to mine plans in response to the physical shape and location of the ore body. In addition, costs at our mines and at our Langeloth Facility are affected by the price of input commodities, such as fuel, electricity, labor, chemical reagents, grinding media, mill liners, explosives, steel and concrete. The costs of our operating consumables are, at times, subject to volatile price movements, including increases that could make production at certain operations less profitable and changes in laws and regulations affecting their price, use and transport. Reported costs may also be affected by changes in accounting standards. A material increase in costs at any significant location could have a significant effect on our profitability and operating cash flow.

Our mining production depends on the availability of sufficient water supplies.

Our operations require significant quantities of water for mining, ore processing and related support facilities. Continuous production at our mines depends on our ability to maintain our water rights and claims. Although our current operations have sufficient water rights and claims to cover current operational demands, we cannot predict the potential outcome of future legal proceedings affecting our water rights, claims and uses. The failure to obtain needed water permits, the loss of some or all water rights for any of our mines, in whole or in part, or shortages of water to which we have rights due to weather, equipment issues or other factors could require us to curtail or close mining production and could prevent us from pursuing expansion opportunities.

A temporary or extended shutdown of any of our operations could expose us to significant costs and adversely affect our access to skilled labor.

From time to time, we may have to temporarily shut down one or more of our operating sites or place one or more of our operating sites on care and maintenance or permanent shutdown, if they are not commercially viable due to factors such as declines in metal prices, increased costs or adverse changes in interest rates or currency exchange rates. For example, our molybdenum mines are currently on care and maintenance due to ongoing weakness in the molybdenum price. During temporary shutdowns or while a site is on care and maintenance, we will have to continue to expend capital to maintain the site or facility and equipment. In addition, reductions in workforce, advance notice requirements under collective labor agreements or applicable law, and severance obligations arising from such suspension or shutdown could cause us to incur significant labor costs. Furthermore, temporary or extended shutdowns may adversely affect our future access to skilled labor, as employees who are laid off may seek employment elsewhere.

In addition, if our operations are shut down for an extended period of time, we may be required to engage in environmental remediation of the plant sites or accelerated reclamation of our mines, which would require us to incur additional costs. The costs of ramping up production at one of our operations following a temporary shutdown could be significant. Given the costs involved in a temporary shutdown of our operations, we may instead choose to continue to operate those operations at a loss. Such a decision could have a material adverse effect on our results of operations and financial condition.

We are subject to substantial government regulation. Changes to regulation or more stringent implementation could have a material adverse effect on our results of operations and financial condition.

Our mining, processing, development and mineral exploration activities are subject to various laws governing prospecting, development, production, taxes, labor standards and occupational health, mine safety, toxic substances and other matters. Mining and exploration activities are also subject to various laws and regulations relating to the protection of the environment. No assurance can be given that we will remain in compliance with applicable regulations or that new rules and regulations will not be enacted or that existing rules and regulations will not be applied in a manner that could limit or curtail production or development of our properties. Amendments to current laws and regulations governing our operations and activities or more stringent implementation thereof could have a material adverse effect on our business, financial condition and results of operations.

Table of Contents

In addition, we are required to expend significant resources to comply with numerous corporate governance and disclosure regulations and requirements adopted by US federal and state and Canadian federal and provincial governments, as well as the Toronto Stock Exchange. These additional compliance costs and related diversion of the attention of management and key personnel could have a material adverse effect on our business, financial condition and results of operations.

Estimates of mineral reserves and projected cash flows may prove to be inaccurate, which could negatively impact our results of operations and financial condition.

There are numerous uncertainties inherent in estimating mineral reserves and the future cash flows that might be derived from production of mineral reserves. Accordingly, the figures for mineral resources, mineral reserves and future cash flows contained in this Form 10-K are estimates only. In respect of mineral reserve estimates, no assurance can be given that the anticipated tonnages and grades will be achieved, that the indicated level of recovery will be realized or that mineral reserves can be mined or processed profitably. The ore grade actually recovered may differ from the estimated grades of the mineral reserves and mineral resources.

In addition, actual future cash flows may differ materially from estimates. Estimates of mineral reserves and future cash flows to be derived from the production of such mineral reserves, necessarily depend upon a number of variable factors and assumptions, including, among others, geological and mining conditions that may not be fully identified by available exploration data or that may differ from experience in current operations; historical production from the area compared with production from other producing areas; the assumed effects of regulation by governmental agencies and assumptions concerning metal prices; exchange rates; interest rates; inflation; operating costs; development and maintenance costs; reclamation and post-reclamation costs; and the availability and cost of labor, equipment, raw materials and other services required to mine and refine the ore. Market price fluctuations of copper, gold and molybdenum, as well as increased production costs or reduced recovery rates, may render mineral reserves containing relatively lower grades of mineralization uneconomical to recover and may ultimately result in a restatement of mineral resources. We may be required to make significant downward revisions to estimates of mineral resources, mineral reserves and future cash flows to be derived from the production of such mineral reserves, if commodity prices experience a sustained decline. In addition, there can be no assurance that mineral recoveries in small scale laboratory tests will be duplicated in larger scale tests under on-site conditions or during production.

For these reasons, estimates of our mineral resources and mineral reserves contained in this Form 10-K, including classifications thereof based on probability of recovery, and any estimates of future cash flows expected from the production of those mineral reserves, prepared by different engineers or by the same engineers at different times may vary substantially. The actual volume and grade of mineral reserves mined and processed, and the actual cash flows derived from that production, may not be as currently anticipated in such estimates. If our actual mineral reserves or cash flows are less than our estimates, our results of operations and financial condition may be materially impaired.

Future growth depends on our ability to bring new mines into production and to expand mineral reserves at existing mines.

Our ability to replenish our mineral reserves is important to our long-term viability. Depleted mineral reserves can be replaced in several ways, including by expanding known ore bodies, locating new deposits or acquiring new mineral reserves from third parties. Exploration projects involve many risks, require substantial expenditures and may not result in the discovery of sufficient additional mineral deposits that can be mined profitably. Once a site with mineralization is discovered, it may take several years from the initial phases of drilling until production is possible, if ever, during which time the economic feasibility of production may change. As a result, there is no assurance that current or future exploration programs, such as the Berg property, and additional drilling at our existing operating mines, will be successful.

We intend to grow our business by acquiring quality mining assets. However, our capital available for new exploration projects and acquisitions is constrained due in large part to our substantial indebtedness incurred in connection with the development of Mount Milligan Mine and declines in metals prices. In addition, there can be no assurance that suitable acquisition opportunities will be identified or, if identified, that acquisitions will be consummated on favorable terms or at all. Our ability to identify, consummate and to integrate effectively any future acquisitions on terms that are favorable to us may be limited by the number of attractive acquisition targets, internal demands on our resources, competition from other mining companies and, to the extent necessary, our ability to obtain financing on satisfactory terms, or at all. In addition, we compete for attractive acquisition targets with other potential buyers that have more financial and other resources than us. There is a risk that depletion of reserves will not be offset by discoveries or acquisitions. As a result, we cannot provide assurance that our exploration, development or acquisition efforts will result in any new commercial mining operations or yield new mineral reserves to replace or expand current mineral reserves. If we are not able to replace depleted reserves, it could have a material adverse effect on our business, prospects, results of operations and financial position.

Table of Contents

Certain of our mines and exploration properties are located on land that is or may become subject to traditional territory and/or title claims by certain First Nations, and such claims and the attendant obligations of the provincial and federal governments to those First Nations may affect our current and future operations.

Mount Milligan Mine, Endako Mine, the Berg property, and the IKE Project are located on land in British Columbia that is or may become subject to various use and/or title claims by First Nations. The nature and extent of First Nations' rights and title to territory in Canada has been, and continues to be, the subject of extensive debate, claims, and litigation. In 2014, the Supreme Court of Canada recognized, for the first time in history, aboriginal title to a certain tract of land in British Columbia. While this recognition does not legally change the consultation and accommodation obligations of the provincial and federal governments with respect to actions affecting the land, including actions to approve or grant mining rights or permits, the decision may impact governmental actions and processes relating to economic development on such lands going forward, which could adversely impact our ability to obtain permits, licenses, and other approvals for our operations or exploration and development projects. Opposition by First Nations to our presence, operations or development on land subject to their traditional territory or title claims could negatively impact us in terms of public perception, costly legal proceedings, potential blockades or other interference by third parties in our operations, or court-ordered relief impacting our operations. In addition, we may be required to, or may voluntarily, enter into certain agreements with such First Nations in order to facilitate development of our properties, which could reduce the expected earnings or income from any future production.

Shortages of critical parts, equipment and skilled labor may adversely affect our operations and development projects.

The mining industry has been impacted, from time to time, by increased demand for critical resources such as input commodities, drilling equipment, milling equipment, tires and skilled labor. These shortages have, at times, impacted the efficiency of our operations and resulted in cost increases and delays related to construction of the new mill at Endako Mine and the construction of Mount Milligan Mine. Such cost increases and delays affect operating costs, capital expenditures and production and construction schedules.

We are required to obtain government approvals and permits in order to conduct operations.

Government approvals and permits are currently required in connection with all of our operations, and further approvals and permits may be required in the future. We must obtain and maintain a variety of licenses and permits, which include or cover without limitation air quality, water quality, water rights, dam safety, emergency preparedness, hazardous materials, waste rock management, solid waste disposal and tailings operations. The duration and success of our efforts to obtain permits are contingent upon many variables outside of our control. Obtaining governmental approvals and permits may increase costs and cause delays depending on the nature of the activity to be permitted and the applicable requirements implemented by the permitting authority. There can be no assurance that all necessary approvals and permits will be obtained or timely obtained or that they would remain in effect if we were forced into a reorganization, bankruptcy or insolvency proceeding. In addition, there can be no assurance that, if obtained, the costs of the approvals and permits will not exceed our estimates or that we will be able to maintain such approvals and permits. To the extent such approvals or permits are required and not obtained or maintained, our operations may be curtailed, or we may be prohibited from proceeding with planned exploration, development or operation of our mineral properties.

Our Langeloth Facility is currently operating with a National Pollutants Discharge Elimination System ("NPDES") permit, the terms of which have expired. However, the Langeloth Facility is authorized to continue to operate under its existing permit until a renewed permit is issued. On June 30, 2014, the Pennsylvania Department of Environmental Protection ("PaDEP") issued to us a final Title V air quality permit for the Langeloth Facility. A new NPDES permit, or revisions to our air quality permit, may contain more onerous requirements with which we must comply, and we could be required to install costly new pollution control equipment or to curtail or cease our operations, and our business may be adversely affected. Violations of the existing, or new, air quality or NPDES permit conditions at the Langeloth Facility could result in a range of criminal and civil penalties under the federal Clean Water Act and Clean Air Act or the Pennsylvania Clean Streams Law or Air Pollution Control Act.

TC Mine is also currently operating with an expired NPDES permit. TC Mine is authorized by federal regulation to continue to operate under its existing permit until the renewed permit is issued. A renewed NPDES permit may contain more onerous requirements with which we must comply, and we could be required to install costly new pollution control equipment or to curtail or cease our operations, and our business may be adversely affected. Violations of the existing, or new, NPDES permit conditions at TC Mine could result in a range of criminal and civil penalties under the federal Clean Water Act.

Our operations plan for Mount Milligan Mine provides that employees have the option to live in an operations residence located on the minesite, and that copper-gold concentrate from the mill will be transported to the District of Mackenzie (as opposed to Fort St. James) to be loaded onto railcars for transport to the Port of Vancouver. To construct and operate an operations residence and to load out concentrate in Mackenzie, we applied for and obtained an amendment to our Environmental Assessment Certificate for Mount Milligan Mine. Any failure to comply with the amendment as issued may have a material adverse effect on our business.

At Endako Mine, we filed an application for an amendment to our permit issued under the British Columbia Mines Act in September 2014. This application is pending before the Ministry of Energy and Mines. The outcome of the Mines Act Permit Amendment (MAPA) may include terms and conditions that impose regulatory or reclamation requirements that may be unacceptable to us or will materially increase our costs during operations and closure of Endako. Moreover, litigation may be filed challenging the MAPA process, which could materially increase our costs, or prevent or delay our ability conduct mining operations at Endako. Obtaining and maintaining the various permits for our mine development operations and exploration projects, including the Berg property, will be complex, time-consuming and expensive. Changes in a mine's design, production rates, quality of material mined and many other matters often require submission of the proposed changes for agency approval prior to implementation, and these may not be obtained. In addition, changes in operating conditions beyond our control, changes in agency policy and federal and state laws, litigation or community opposition could further affect the successful permitting of operations.

Title to some of our mineral properties may be challenged or defective. Any impairment or defect in title could have a negative impact on our results of operations and financial condition.

The acquisition of title to mineral properties is a very detailed and time-consuming process. There is no guarantee that title to any of our properties will not be challenged or impaired. Third parties may have valid claims underlying portions of our interests, including prior unregistered liens; agreements; transfers or claims, including aboriginal land claims; and title may be affected by, among other things, undetected defects. As a result, we may be constrained in our ability to operate our properties or unable to enforce our rights with respect to our properties. An impairment to, or defect in, title to our properties could have a material adverse effect on our business, financial condition or results of operations.

Major network failures could have an adverse effect on our business.

Major equipment failures, natural disasters including severe weather, terrorist acts, acts of war, cyber-attacks or other breaches of network systems or security that affect computer systems within our network could disrupt our business functions, including our production activities. Our mines and mills are automated and networked such that a cyber incident involving our information systems and related infrastructure could negatively impact our operations. A corruption of our financial or operational data or an operational disruption of our production infrastructure could, among other potential impacts, result in: (i) loss of production or accidental discharge; (ii) expensive remediation efforts; (iii) distraction of management; (iv) damage to our reputation or our relationship with customers; or (v) in events of noncompliance, which events could lead to regulatory fines or penalties. Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.

Environmental Risks

We must comply with comprehensive environmental statutes, regulations and other governmental controls, and we face significant environmental risks.

All phases of our operations are subject to environmental regulation. In Canada and the United States, environmental laws provide for, among other things, restrictions and prohibitions on spills, releases, emissions and discharges of various substances produced in association with, or resulting from, our operations. These laws also require that facility sites and mines be operated, maintained and reclaimed to the satisfaction of applicable regulatory authorities, including long-term obligations. Compliance with such laws, including without limitation, detailed monitoring and reporting requirements, require significant expenditures. An exceedance of a permit limitation or failure to comply with a permit requirement may result in the imposition of fines and penalties, some of which may be material. Companies engaged in the exploration, development and operation of mineral properties often experience increased costs and delays as a result of compliance with applicable laws, regulations and permits.

For example, a decision to mine Phase 8 (the next phase of production) at TC Mine would entail expansion of some facilities, with additional permitted surface disturbance on approximately 200 acres of US Bureau of Land Management ("BLM") administered land, 185 acres of National Forest System land and approximately 110 acres of private land owned by us. As a result, the mining of Phase 8 is subject to environmental analysis and preparation of an environmental impact statement ("EIS") pursuant to the federal National Environmental Policy Act ("NEPA"). The EIS also covers a proposed land exchange in which we would receive approximately 5,000 acres of BLM land in exchange for 900 acres of private lands owned by us. The BLM is the lead agency for preparation of the EIS and other federal and state agencies are cooperating agencies. The EIS was completed in early-2015 and will be the basis for Records of Decision (RODs) issued by both the BLM and the United States Forest Service to approve our proposed Modified Mine Plan of Operations, by the BLM to approve the proposed land exchange (including a related amendment of the Resource Management Plan for the BLM's Challis Resource Area) and by the US Army Corps of Engineers to approve issuance of a permit under section 404 of the Clean Water Act. There is no assurance that the RODs will be issued, or that these documents will be completed or issued on terms and conditions acceptable to us. The agencies' preferred alternatives in the EIS, or consultation pursuant to the Endangered Species Act, may include terms and conditions that impose regulatory or reclamation requirements that will materially increase our costs during operations and closure of TC Mine. Moreover, litigation may be filed challenging the NEPA process for the mine expansion or the land exchange and the result thereof, which could materially increase our costs, or prevent or delay our ability to implement the expansion or the land exchange.

Similarly, at Endako Mine, we filed an application for an amendment to our permit issued under the British Columbia Mines Act in September 2014. This application is pending before the Ministry of Energy and Mines. The Mines Act Permit Amendment (MAPA) may be affected by the outcome of an Aquatic Effects Monitoring Program (AEMP) required by the B.C. Ministry of Environment in a March 2014 amendment to our Effluent Permit issued under the Environmental Management Act. The outcome of the AEMP and MAPA processes may include terms and conditions that impose regulatory or reclamation requirements that will materially increase our costs during operations and closure of Endako Mine. Moreover, litigation may be filed challenging the MAPA process, which could materially increase our costs, or prevent or delay our ability conduct mining operations at Endako Mine.

Environmental regulation is evolving in a manner that may require stricter standards and enforcement, increased fines and penalties for noncompliance, more stringent environmental assessments of proposed projects, and a heightened degree of training and responsibility for companies and their officers, directors and employees. Existing or future environmental regulation could have a material adverse effect on our business, financial condition and results of operations. We own or have owned, manage or have been in care or control of properties that may result in a requirement to environmentally remediate such properties that could involve material costs. In addition, environmental conditions or hazards may exist on the properties in which we hold interests that are unknown to us at present or that have been caused by previous or existing owners or operators of the properties. We may also acquire properties with environmental risks, and the indemnification proceeds we receive from the entity we acquire such properties from, if any, may not be adequate to pay all the fines, penalties and costs (including costs of remediation or removal and related response costs) incurred at or related to such properties.

Failure to comply with applicable laws, regulations and permitting requirements may result in enforcement actions, including compliance and other orders issued by regulatory or judicial authorities causing operations to cease or be curtailed, and may include corrective measures requiring capital expenditures, installation of additional equipment, operation or administration costs or other remedial actions. Parties engaged in mining operations, including us, may be required to compensate those suffering loss or damage to person or property by reason of the mining activities and may have civil or criminal fines or penalties imposed for violations of applicable laws or regulations. Amendments to current laws, regulations and permits governing operations and activities of mining companies, or more stringent implementation or enforcement thereof, could have a material adverse impact on us and cause increases in exploration expenses, remedial and reclamation obligations, capital expenditures or production costs, reduction in levels of production at producing properties, or abandonment of or delays in development of new mining properties.

Regulation of greenhouse gas emissions effects and climate change issues may adversely affect our operations and markets.

Global climate change continues to attract considerable public, scientific and regulatory attention, and greenhouse gas emission regulation is becoming more commonplace and stringent. As energy, including energy produced from the combustion of carbon-based fuels, is a significant input to our mining and processing operations, we must also comply with emerging climate change regulatory requirements, including programs to reduce greenhouse gas emissions. Our principal energy sources are electricity, purchased petroleum products and natural gas. In addition, our processing facilities and mobile mining equipment emit carbon dioxide.

Table of Contents

On July 1, 2008, the Province of British Columbia introduced a carbon tax on the purchase or use of fossil fuels within the province. The current carbon tax rate is $30 per tonne of carbon dioxide equivalent emissions. British Columbia has determined to maintain the carbon tax, but not to increase the rate. Endako Mine and Mount Milligan Mine are located in British Columbia, and the carbon tax may have a material impact on our energy and compliance costs.

The US federal and state governments may also enact an emission trading or similar program for greenhouse gas emissions, which could significantly increase our energy and regulatory compliance costs. For example, the US federal government has considered legislation to reduce greenhouse gas emissions through a cap-and-trade system of allowances and credits, among other provisions. In addition, the US Environmental Protection Agency has developed final rules requiring certain emitters of greenhouse gases to collect and report data with respect to their greenhouse gas emissions.

We are in the process of evaluating the potential impacts on our operations of these new and potential regulations. Either a carbon tax or a cap-and-trade program will likely result in increased future energy costs. The regulations will also likely increase our compliance costs. For example, we may be required to install new equipment to reduce emissions from our processing facilities in order to comply with new regulatory standards or to mitigate the financial impact of a new climate change program. We also may be subject to additional and extensive monitoring and reporting requirements. It is uncertain at this time how provincial and regional initiatives will interact with any federal climate change regulations.

The potential physical impacts of climate change on our operations are highly uncertain and may be particular to the unique geographic circumstances associated with each of our facilities. These may include changes in weather and rainfall patterns, water shortages, changing storm patterns and intensities and changing temperatures. These physical impacts could require us to curtail or close mining production and could prevent us from pursuing expansion opportunities. These effects may adversely impact the cost, production and financial performance of our operations.

We must remove and reduce impurities and toxic substances naturally occurring in copper, gold and molybdenum and comply with applicable law relating thereto, which could result in remedial action and other costs.

Mineral ores and mineral products, including copper, gold and molybdenum ore and products, contain naturally occurring impurities and toxic substances. Although we have implemented procedures that are designed to identify, isolate and safely remove or reduce such impurities and substances, such procedures require strict adherence and no assurance can be given that employees, contractors or others will not be exposed to or be affected by such impurities and toxic substances, which may subject us to liability. Standard operating procedures may not identify, isolate and safely remove or reduce such substances. Even with careful monitoring and effective control, there is still a risk that the presence of impurities or toxic substances in our products may result in such products being rejected by our customers, penalties being imposed due to such impurities or the products being barred from certain markets. Such incidents could require remedial action and could result in curtailment of operations. Legislation requiring manufacturers, importers and downstream users of chemical substances, including metals and minerals, to establish that the substances can be handled and used without negatively affecting health or the environment may impact our operations and markets. These potential compliance costs, litigation expenses, regulatory delays, remediation expenses and operational costs could negatively affect our financial results.

Other Risks

We own certain assets through joint ventures, and any disagreement or failure of partners to meet obligations could have a material adverse effect on our results of operations and financial condition.

Endako Mine is operated as a joint venture between our subsidiary, TCML, which holds a 75% interest, and Sojitz, which holds the remaining 25% interest. As a result, our interest in Endako Mine is subject to the risks normally associated with the conduct of joint ventures. While we are the operator of Endako Mine, Sojitz has certain consent and veto rights pursuant to the agreement governing the joint venture. Any disagreement between us and Sojitz or Sojitz's failure to meet its obligations to the joint venture could have a material adverse impact on our profitability or the viability of our interests held through joint ventures, which could have a material adverse impact on our future cash flows, earnings, results of operations and financial condition.

Table of Contents

Intense competition could reduce our market share or harm our financial performance.

The mining industry is intensely competitive, and we compete with many companies that have more financial and technical resources than we do. Our competitive position is based on the quality and grade of our mineral reserves, our operating performance, our ability to manage our costs compared to other producers throughout the world, our ability to maintain our financial integrity through the lows of the metal price cycles and our ability to manage our customer relationships. Our costs are governed to a large extent by the location, grade and nature of our mineral reserves; our input costs including energy, labor and equipment; and our operating and management skills. The metals markets are cyclical, and our ability to maintain our competitive position over the long term is based on our ability to manage our costs, acquire and develop quality deposits and hire and retain a skilled workforce. We intend to continue to grow our business through our exploration program and through future acquisitions; however, in the near term our substantial indebtedness will limit our ability to significantly grow our business. Our competitors may have an advantageous market position and have greater financial and other resources and may, therefore, be able to better withstand poor and volatile market conditions, obtain financing on better terms and attract better or more qualified employees, any of which may have an adverse impact on our business, financial condition and results of operations.

We are dependent upon key management personnel and executives.

We are dependent upon a number of key management personnel. Our ability to manage our financial, operating, legal, development and exploration activities, and hence our success, depend in large part on the efforts of these individuals. We face intense competition for qualified personnel, and there can be no assurance that we will be able to attract and retain such personnel. We do not maintain "key person" life insurance. Accordingly, the loss of the services of one or more of such key management personnel could have a material adverse effect on our business.

Our business depends on good relations with our employees.

Production at our operations depends on the efforts of our employees. Endako Mine and Langeloth Facility each have certain unionized employees. The labor agreement currently in place with respect to the unionized employees at our Langeloth Facility is effective through March 11, 2016, and the labor agreement currently in place with respect to the unionized employees at Endako Mine is effective through March 31, 2015, with continuation under existing terms until either party provides notice requiring negotiation of a new collective bargaining agreement. Although our unionized employees have agreed to "no-strike" clauses during the terms of their respective union agreements, there can be no assurance that Endako Mine and Langeloth Facility will not suffer from work stoppages. A strike, lockout or other work stoppage at one or both of these operations could have a material adverse effect on our business, results of operations and financial condition. There can be no assurance that one or both union agreements will be renewed on a timely basis and on terms favorable to us. There is also a possibility that our employees at TC Mine and Mount Milligan Mine could organize and certify a union in the future.

Further, changes in governmental regulations relating to labor relations, or otherwise in our relationship with our employees, including our unionized employees, may result in strikes, lockouts or other work stoppages, any of which could have a material adverse effect on our business, results of operations and financial condition.

Unfavorable outcomes of legal proceedings may adversely affect our business and financial condition.

We are from time to time involved in or subject to legal proceedings related to our business. Such legal proceedings can be complex, costly, and highly disruptive to business operations by diverting the attention and energies of management and other key personnel. The assessment of the outcome of legal proceedings, including our potential liability, if any, is a highly subjective process that requires judgments about future events that are not within our control. The outcome of litigation, arbitration or other legal proceedings, including amounts ultimately received or paid upon judgment or settlement, may differ materially from management's outlook or estimates, including any amounts accrued in the financial statements. Actual outcomes, including judgments, awards, settlements or orders, could have a material adverse effect on our business, financial condition, operating results, or cash flows.

Our stock price may be volatile and your investment in our common stock could suffer a decline in value. In addition, your investment in our common stock could suffer significant dilution if we convert a significant portion of our outstanding debt to equity in connection with a debt restructuring transaction.

Broad market and industry factors may adversely affect the price of our common stock, regardless of our actual operating performance. Factors that could cause fluctuation in the price of our common stock may include, among other things:


•	changes in financial estimates by us or by any securities analysts who might cover our stock;


•	speculation about our business in the press or the investment community;


•	conditions or trends in our industry, the market or the economy generally;

Table of Contents


•	changes in the prices of copper, gold or molybdenum;


•	stock market price and volume fluctuations of other publicly traded companies and, in particular, those that are in the mining industry;


•	the inability to service or restructure our debt;


•	changes in our credit rating or future prospects;


•	announcements by us or our competitors of significant acquisitions, strategic partnerships or divestitures;


•	capital commitments;


•	failure to meet the conditions necessary to remain listed for trading on the Toronto Stock Exchange (“TSX”), OTCQX or other similar markets;


•	additions or departures of key personnel;


•	changes in accounting standards, policies, guidance, interpretations or principles, or the failure to comply with accounting standards applicable to us or to maintain effective internal control over financial reporting; and


•	sales of our common stock, including sales by our directors, officers or significant stockholders.

In the past, securities class action litigation has often been instituted against companies following periods of volatility in their stock price. This type of litigation could result in substantial costs to us and divert our management’s attention and resources. In addition, in connection with a restructuring or refinancing, we may seek to convert a significant portion of our outstanding debt to equity, including the exchange of debt for shares of our common stock, which could result in substantial dilution to our current shareholders.

If we cannot meet the TSX continued listing requirements, our common stock may be delisted from the TSX.

On January 14, 2016, the NYSE suspended trading of our common stock on the NYSE due to current stock levels and our common stock was subsequently delisted from the NYSE. On January 15, 2016, our common stock began trading on the OTCQX under the stock symbol "TCPTF." Our common stock continues to be listed on the Toronto Stock Exchange (TSX).

The TSX has rules for continued listing, including minimum market capitalization and other requirements. If we fail to meet the continued listing requirements of the TSX, for example, due to a decrease in our market capitalization, our common stock may be delisted. A delisting of our common stock could negatively impact us and investors may face material adverse consequences, including, but not limited to, a lack of trading market for our common stock, decreased liquidity, reducing the number of investors willing to hold or acquire our common stock, which could negatively impact our ability to raise equity or debt financing to fund our operations, decreased analyst coverage for our common stock, and limited ability to issue additional securities or obtain additional financing in the future. In addition, delisting from the TSX might negatively impact our reputation and, as a consequence, our business.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 3. LEGAL PROCEEDINGS

We are from time to time involved in or subject to legal proceedings related to our business. While it is not feasible to predict or determine the outcome of such proceedings, it is the opinion of management that the resolution of such proceeding is not expected to have a material adverse effect on our consolidated financial position, results of operations or cash flows.

ITEM 4. MINE SAFETY DISCLOSURES

Under Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, mine operators are required to include in their periodic reports filed with the SEC certain information concerning mine safety violations and other regulatory matters. The required information is included in Exhibit 95 to this report.

See "Financial Review" and "Liquidity and Capital Resources" in this MD&A for additional information related to highlights.

Overview

We are a North American mining company. In 2015, we shifted the core focus of our business to copper and gold while at the same time developing a strategy to maintain the optionality of our molybdenum business. This shift in core focus was primarily the result of expected ongoing weakness in the molybdenum market due to an overall weak global economy for molybdenum products.

We have three reportable segments, based on products and geography: Copper-Gold, US Molybdenum and Canadian Molybdenum. The Copper-Gold segment represents the Mount Milligan Mine and includes the sale of copper-gold products, net of refining costs, and all expenditures, including all mining, milling, mine site general and administration, transportation and warehousing. The US Molybdenum segment includes all molybdenum sales from TC Mine and from the sale of third party molybdenum purchases as well as tolling and calcining revenue from Langeloth, all roasting and on-site administrative expenditures from Langeloth and all expenditures from TC Mine, which was placed on care and maintenance in December 2014, including all mine site general and administration costs, stripping costs for the first nine months of 2015, molybdenum beneficiation test-work costs and costs for idle mining operations. The Canadian Molybdenum segment includes all molybdenum sales from the 75% owned Endako Mine, which was placed on care and maintenance effective July 1, 2015, and our 75% share of expenditures from Endako Mine, including all mine site general and administration costs, severance costs, transportation costs, and costs for idle mining operations. Our 75% share of the care and maintenance and temporary suspension costs at Endako Mine along with the care and maintenance costs at TC Mine are reflected in costs for idle mining operations in the Condensed Consolidated Statements of Operations and Comprehensive Loss for the year ended December 31, 2015.

Copper-Gold

During 2015 we completed 15 shipments of copper and gold concentrate and recorded 15 sales, compared to 12 shipments of copper and gold concentrate and 12 sales in 2014. Our 2015 and 2014 shipments had an average weight

of approximately 10,000 dry tonnes.

For the fourth quarter of 2015 compared to the fourth quarter of 2014, payable copper production increased 8.0% primarily due to improved throughput and non-GAAP copper cash costs on a by-product basis decreased 31.9% primarily due to a 23.7% increase in gold sales together with a favorable Canadian exchange rate. These favorable changes were partially offset by higher costs for temporary secondary crushing and mill maintenance. For the fourth quarter of 2015, on a co-product basis, non-GAAP copper cash costs decreased by 26.1%, compared to the fourth quarter of 2014, primarily due to the favorable Canadian exchange rate.

Payable copper production increased 10.6% and non-GAAP copper cash costs on a by-product basis decreased 52.2% for fiscal year 2015 from 2014. Year over year, the increase in payable production was due to improved throughput, while the decrease in non-GAAP copper cash costs was primarily due to a 21.8% increase in gold sales in 2015. On a co-product basis, non-GAAP copper cash costs for 2015 decreased 21.3% from 2014, primarily due to higher payable copper production and a favorable Canadian exchange rate in 2015 compared to 2014. See “Non-GAAP Financial Measures” for the definition and reconciliation of non-GAAP cash costs.

Table of Contents

Payable gold production for the fourth quarter of 2015 increased 42.2% compared to the fourth quarter of 2014, with an 8.5% decrease in non-GAAP cash costs on a co-product basis, quarter over quarter. Quarter over quarter, the increase in payable production was primarily due to improved grade and recoveries and the decrease in non-GAAP unit cash costs was primarily due to an increase in gold production.

Payable gold production for 2015 increased 22.8% from 2014 primarily due to improved throughput and recoveries, with a 9.0% decrease in non-GAAP cash costs on a co-product basis period over period. Year over year, the decrease in unit cash costs on a co-product basis was primarily due to an increase in gold production in 2015. Cash costs during 2015 were impacted by the favorable Canadian exchange rate, as noted above. See “Non-GAAP Financial Measures” for the definition and reconciliation of non-GAAP cash costs.

During the fourth quarter of 2015, the average daily mill throughput was 48,176 tpd, as compared to 43,781 tpd for the fourth quarter of 2014. During 2015, the average daily mill throughput was 44,214 tpd, as compared to 39,151 tpd for 2014. During the fourth quarter of 2015, recoveries averaged 79.3% for copper and 67.3% for gold, compared to 79.0% for copper and 60.8% for gold during the fourth quarter of 2014. During 2015 recoveries averaged 80.2% for copper and 68.6% for gold compared to 80.4% for copper and 63.1% for gold in 2014.

During the fourth quarter of 2015, mill availability was unfavorably impacted by the installation of a second SAG discharge screen deck to address overloading and recirculation issues. In addition to the scheduled shutdown to install the second SAG discharge screen deck, mill availability for the quarter was also unfavorably impacted by unscheduled shutdowns to reline mills and perform cleaning and maintenance on the SAG mill motors.

At year-end 2015, we achieved our goal of completing the ramp up process at the Mount Milligan Mine, with average daily mill throughput above 60,000 tonnes. During December, average daily mill throughput at the Mount Milligan Mine was 51,677 tonnes, with a daily average of 45,097 tonnes during the first half of the month and 57,847 tonnes during the second half of the month. Additionally, average daily mill throughput for the last week of December was 61,212 tonnes, with the highest day in December of 64,478 tonnes.

As a result of successfully addressing mechanical issues together with the continued addition of crushed material utilizing a temporary secondary crushing circuit, during the second half of December 2015 and during January 2016 we began to realize significant throughput improvements. During January we achieved 17 days of daily mill throughput above 60,000 tonnes of which 12 days were over 62,000 tonnes. We achieved a record daily mill throughput of 65,599 tonnes on January 9, 2016. We expect mill throughput to fluctuate from time to time due to maintenance shutdowns and other operational matters, and results for any period are not necessarily indicative of future results. With the increase in throughput after the recent step change improvements in the SAG mill discussed above, we have experienced a decline in January recoveries primarily due to below average performance in the ball mill, regrind and flotation circuits. The variables affecting performance in these circuits are being evaluated and action plans being developed to improve metal recovery. It is expected that staged improvements will be achieved over the next few months. As a result, first quarter 2016 recoveries are expected to be approximately 4%-6% lower than those in the fourth quarter of 2015.

We believe that a permanent secondary crushing circuit will increase the value of Mount Milligan Mine by providing more reliable throughput levels for the long-term at lower cost than what we can achieve with the temporary secondary crushing circuit. We have made the decision to move forward with the construction of the permanent secondary crushing circuit which we expect will enable us to consistently achieve average daily throughput of approximately 62,500 tpd. The permanent secondary crushing circuit is expected to be completed in the fourth quarter of 2016. The estimated total capital cost for the permanent secondary crushing circuit is expected to be in the range of $60 - $65 million. Of this total estimate, we incurred approximately $15.0 million in 2015 for engineering and concrete work and long lead items. Of the amount incurred in 2015, approximately $6.2 million was accrued as of December 31, 2015. In the fourth quarter of 2015, we made the decision to order the long-lead items for the permanent crusher and take additional steps in preparation for construction, and in the first quarter of 2016 we made the decision to commence construction. In 2016 we expect to spend $27 million for the long-lead items and other pre-construction items and an additional $20 million for the construction, plus or minus 10%. As discussed above, with construction commencing in February 2016, we believe we will be able to complete construction and commissioning by the end of 2016. Once installed and commissioned, we expect that the permanent secondary crusher will allow us to increase daily mill throughput to approximately 62,500 tonnes.

The government of British Columbia has announced a five-year power rate deferral program involving British Columbia’s crown corporation, BC Hydro. Final details of the program have not yet been publicly announced, but it is anticipated that mines operating in British Columbia may elect to participate in the program and enter into an agreement with BC Hydro under which a portion of such mine’s power bill may be deferred for a certain period of time, with deferred amounts accruing interest at a rate to be negotiated between the mining company and BC Hydro. We are monitoring this proposed program and assessing the potential participation of Mount Milligan Mine.

See “Selected Consolidated Financial and Operational Information” and “Segment Discussion” in this MD&A for additional information for our copper-gold operations during 2015 and 2014.

Molybdenum

In 2015 we transformed our business strategy for molybdenum to maximize the location and efficiency of our Langeloth Facility near Pittsburgh, Pennsylvania. We provide tolling services for customers by converting molybdenum concentrates to molybdenum oxide powder and briquettes and ferromolybdenum products. Additionally, we also purchase molybdenum concentrates to convert to upgraded products which are then sold in the metallurgical and chemical markets. Going forward, we expect Langeloth to generate sufficient cash flow to substantially cover the annual costs of care and maintenance at our two molybdenum mines enabling us to hold our molybdenum business on a cash neutral basis allowing us to retain the optionality to re-start our mines if a more favorable market presents itself.

During 2015, we shut down our sulfuric acid plant and molybdenum roasters to complete scheduled maintenance at Langeloth, which included replacement of the sulfur burner and general maintenance. Production at the molybdenum roasters resumed at the beginning of the fourth quarter of 2015. This planned maintenance will allow us to be successfully positioned to accomplish our goal of being one of the leading molybdenum conversion plants in the world. During 2015, we had cash capital expenditures of $5.6 million at our Langeloth facility related to this project.

During the quarter and year ended December 31, 2015, the molybdenum business generated net cash flows (net of capital expenditures) of approximately $1 million and $21 million, respectively, principally as a result of selling inventory mined in 2014 and realizing net trade receivables generated during prior year. During the quarter and year ended December 31, 2015, we sold 2.7 million and 12.1 million pounds of molybdenum, respectively at an average realized price of $6.39 and $8.55 per pound, respectively.

As previously disclosed, in December 2014, TC Mine was placed on care and maintenance after completing the processing of stockpiled ore from Phase 7. During the first seven months of 2015, we conducted limited stripping of waste at the mine for the next phase of mining; however, due to the continued weakness in the molybdenum market, we stopped the stripping project in early August 2015. For the year ended December 31, 2015, TC Mine incurred approximately $7.7 million in care and maintenance costs and $3.2 million in stripping costs. As of January 2016, we are operating a commercial molybdenum beneficiation circuit at our TC Mine to treat molybdenum concentrates to supplement the concentrate feed we source directly for our Langeloth facility. This follows a series of test runs conducted in 2015 with a variety of different concentrates, as a result of which, we concluded that we could profitably process high copper molybdenum concentrate through a beneficiation process at TC Mine, which is then transported to Langeloth for processing. In connection with the beneficiation test-work, for the year ended December 31, 2015, we incurred $3.7 million in costs, which are included in operating expenses in our Consolidated Statement of Operations and Comprehensive Loss.

Effective July 1, 2015, Endako Mine was placed on care and maintenance due to continued weakness in the molybdenum price. During 2015, we incurred approximately $15.9 million of temporary suspension and care and maintenance costs at Endako Mine, inclusive of one-time severance costs of $6.7 million, which represented our 75% share of such costs. We estimate that our share of care and maintenance costs in 2016 will be approximately $2 - $3 million, using an exchange rate of US$1.00 = C$1.35.

See “Selected Consolidated Financial and Operational Information” and “Operating Segment Discussion” in this MD&A for additional information for our molybdenum operations during 2015 and 2014.

Commodity Prices

Our financial results can vary significantly as a result of fluctuations in the market prices of copper, gold and molybdenum and fluctuations in our production. World market prices for our products have fluctuated historically and are affected by numerous factors beyond our control. Any significant fluctuation in demand or prices may have a material effect on our operating results, cash flows and financial condition.

We have a hedging program in place to provide downside protection for copper and gold prices for 2015. See Note 6 for more information regarding our copper and gold financial instruments. See Item 1A, "Risk Factors" for a discussion of risks relating to commodity prices and commodity hedging activities.

Liquidity

Our cash and cash equivalents balance was $176.8 million at December 31, 2015 compared to $265.6 million at December 31, 2014. The decrease in our cash balance is primarily related to lower sales volumes from our molybdenum business, lower average realized sales prices for our copper, gold and molybdenum, capital expenditures of $61.3 million and the repurchase and retirement of $41.4 million of our 2017, 2018 and 2019 Notes ("Senior Notes"), partially offset by $19.8 million of tax refunds, of which $9.7 million has been accounted for as a net liability for unrecognized tax benefits due to an uncertain tax position primarily related to timing differences for certain deductions. Total cash used in 2015 for the note repurchases was $44.8 million, which also included the payment of interest of $1.3 million accrued up to the respective repurchase dates and a net premium of $2.0 million over the face value of the Senior Notes. Since the inception of the bond repurchase program in December 2014, we have repurchased and retired $67.1 million of our 2017, 2018 and 2019 Notes, with total cash used for these retirements of $68.2 million, which included the payment of interest of $1.6 million accrued up to the repurchase dates and $0.5 million net discount on the face value. Total future interest savings to maturity from these Senior Notes repurchases is approximately $21.5 million. Since the completion of the Mount Milligan Mine through December 31, 2015, we have repaid and retired approximately 13% of our debt balance, or approximately $133.6 million, including the net repayments of our capital lease obligations.

Copper and gold prices, the operating performance of our Mount Milligan Mine, the US$ to C$ foreign exchange rate and the scheduled maturities of our outstanding Senior Notes are the critical drivers of our liquidity and credit quality. We believe that estimated cash flow from our Mount Milligan Mine, together with cash on hand as of December 31, 2015, will provide sufficient liquidity to fund our planned capital expenditures, working capital needs and scheduled debt and interest payments until our outstanding Senior Notes come due, beginning in December 2017. This liquidity outlook assumes a spot price of approximately $2.00 per pound for copper, a spot price of approximately $1,000 per ounce for gold, a US$ to C$ foreign exchange rate of approximately US$1.00 = C$1.35, and financial assurance obligations, including assurances related to our reclamation obligations, substantially consistent with our current obligations.

The significant decline in copper prices in 2015 and the continuing and expected weakness in the base metals market has materially impacted our ability to generate sufficient cash flow from operations to fully repay our outstanding Senior Notes when they come due, and, as a result, our credit quality has declined and our long-term liquidity has been adversely affected. As previously disclosed, we have engaged financial advisors to assist us in evaluating strategic and financial alternatives available to us to de-lever the balance sheet and complete a capital refinance/restructure in order to insure that we can continue to operate with sufficient liquidity in the longer term while providing a platform for future growth opportunities. Our ability to refinance or restructure our debt or obtain additional financing is subject to a number of risks and uncertainties, and there can be no assurance that we will successfully complete a restructuring or refinancing on favorable terms or at all. Please refer to the "Liquidity and Capital Resources" section in this MD&A and Part I, Item 1.A “Risk Factors” for further discussion.

Outlook

Table of Contents

Based on recent and continuing weakness in the copper price and the relative strength of the gold price, together with management’s expectations of metals prices in 2016, the mine plan for Mount Milligan Mine will emphasize production from zones with a higher gold grade. The mine plan underlying our 2016 guidance presented below was modified as compared to the mine plan presented in the National Instrument 43-101 ("NI 43-101") technical report. For additional information refer to our discussion in Item1 under the subheading Mineral Reserves.

As a result of this modification, we currently estimate that in 2016 our payable copper production will decrease approximately 10% to 25% and payable gold production will increase approximately 10% to 25%, as compared to actual payable copper and gold production in 2015. Depending upon the level of gold production and gold sales together with C$ to US$ exchange rates, cash costs on a by-product basis are estimated to be $0.25 to $0.70 per pound of copper in 2016. While our molybdenum business has been scaled back significantly due to the placement of TC Mine and Endako Mine on care and maintenance, we estimate that cash flows from the Langeloth Facility will be sufficient to substantially cover the cash costs and cash capital expenditures of the our molybdenum business during 2016, resulting in our molybdenum business being at or near cash neutral.

The following table presents our guidance for the full year 2016.




		Year Ending December 31, 2016 (Estimated)
Mount Milligan Mine Copper and Gold ⁽¹⁾
Concentrate production (000's dry tonnes)		125 - 135
Copper payable production (000's lb)		55,000 - 65,000
Gold payable production (000's oz) ⁽¹⁾		240 - 270
Unit cash cost - By-product ($/payable lb copper produced): ⁽²⁾		$0.25 - $0.70

Cash Capital Expenditures ($ in millions, plus or minus 10%):
Mount Milligan operations		$5
Mount Milligan tailings dam		$20
Mount Milligan secondary crusher ⁽³⁾		$47
Total capital expenditures		$72

_______________________________________________________________________________


⁽¹⁾	Estimates for cash costs and capital expenditures assume an average foreign exchange rate of US$1.00 = C$1.35 for 2016.


⁽²⁾	Assumes gold by-product credits at a weighted average gold price of $750/oz, which takes into account the $435/oz under the streaming arrangement with Royal Gold ("Gold Stream Arrangement").

⁽³⁾

Excludes $6.2 million in accruals as of December 31, 2015 that will be paid in 2016. The guidance we issued on January 14, 2016 showed a capital expenditure estimate for the permanent secondary crusher of $27 million. We noted that if we decided to move forward with the construction of the permanent secondary crusher in 2016, the estimate would increase by approximately $20 million. Now that we have made the decision to move forward with construction in 2016, we have increased the estimated capital expenditure by the $20 million (plus or minus 10%) expected to be incurred in connection with the construction and commissioning of the permanent secondary crusher.

See Item 1A for a discussion of risk factors relating to our production and cost guidance.

Three Months Ended December 31, 2015 (Unaudited)

Net Income (Loss)

Net income for the fourth quarter of 2015 was $12.9 million, or $0.06 per diluted share, compared to a net loss of $135.6 million, or $0.63 per diluted share for the fourth quarter of 2014. Net income in the fourth quarter of 2015 was primarily the result of a tax benefit of $58.9 million and operating income of $3.2 million, partially offset by non-cash foreign currency losses of $28.3 million primarily related to intercompany notes and interest and finance fee expense of $21.1 million. Net loss in the fourth quarter of 2014 was primarily the result of non-cash write downs of the molybdenum long-lived assets and materials and supplies inventory of $79.5 million, exploration property write downs of $25.3 million, molybdenum product inventory write downs of $25.5 million and non-cash foreign currency losses of $35.3 million primarily related to intercompany notes.

Non-GAAP adjusted net loss for the fourth quarter of 2015 (which excluded the non-cash impact of foreign exchange losses related to intercompany notes, net of tax impacts and a non-cash release of tax valuation allowances) was $17.1 million, or $0.08 per diluted share. Non-GAAP adjusted net loss for the fourth quarter of 2014 (which excluded asset impairments, net of tax impacts, and the non-cash impact of primarily unrealized foreign exchange losses, net of tax impacts) was $10.0 million, or $0.05 per diluted share.

Revenues

Revenues in the fourth quarter of 2015 were $95.3 million, down 43.3% compared to revenues of $168.0 million for the fourth quarter of 2014. Quarter over quarter the decrease in revenues was driven primarily by lower molybdenum sales due to TC Mine and Endako Mine being placed on care and maintenance and lower average realized sales prices of copper and gold, partially offset by higher gold sales volumes. During the fourth quarter of 2015, we sold 16.1 million pounds of payable copper at an average realized sales price of $1.92 per pound of copper and 51,781 ounces of payable gold at an average realized sales price of $932 per ounce of gold. During the fourth quarter of 2014, we sold 15.5 million pounds of payable copper and 38,910 ounces of payable gold at average realized sales prices of $2.75 per pound of copper and $1,003 per ounce of gold, respectively.

During the fourth quarter of 2015 and 2014, we sold 2.7 million and 8.1 million pounds of molybdenum, respectively at an average realized price of $6.39 and $10.79 per pound, respectively.

Operating Expenses

Operating expenses for the fourth quarter of 2015 were $58.8 million, which were down 54.3% from the same quarter in 2014. Quarter over quarter, the decrease in operating expenses was primarily due to our molybdenum mines being placed on care and maintenance together with the favorable impact of Canadian foreign exchange rates on our copper-gold operating expenses, partially offset by the costs of temporary secondary crushing.

Lower-of-cost-or-market/net realizable value product inventory write downs within operating expenses for each reportable segment during the three months ended December 31, 2015 and 2014 were as follows:



	Three Months Ended December 31,
	2015		2014
US Operations Molybdenum	$	3.4	$	2.1
Canadian Operations Molybdenum	—		11.5
	$	3.4	$	13.6

Molybdenum product inventory write downs in the fourth quarter of 2015 were primarily related to third party purchased product and were the result of declining prices. Molybdenum product inventory write-downs in the fourth quarter of 2014 were primarily the result of higher cost production from Endako Mine together with declining prices.

As mentioned above, quarter over quarter operating expenses were favorably impacted by foreign exchange rates. The foreign exchange rate averaged US$1.00 = C$1.34 for the fourth quarter of 2015 compared to an average rate of US$1.00 = C$1.14 for fourth quarter of 2014.

Table of Contents

The non-GAAP financial measure of cash cost per pound produced from Mount Milligan Mine in the fourth quarter of 2015 was $0.79 per pound of payable copper produced, on a by-product basis, $1.39 per pound of payable copper produced on a co-product basis and $463 per ounce of payable gold produced on a co-product basis. The by-product cash cost for copper for the fourth quarter of 2015 was favorably impacted by a higher volume of gold ounces sold, partially offset by a lower average realized sales price for gold in the fourth quarter of 2015 as compared to the fourth quarter of 2014.

Depreciation, Depletion and Amortization Expense ("DD&A")

DD&A in the fourth quarter of 2015 was $20.9 million compared to $21.6 million in the fourth quarter of 2014. Quarter over quarter the decrease in DD&A is primarily due to significantly lower sales of molybdenum inventory, together with the absence of ongoing DD&A for TC Mine and our share of Endako Mine as a result of our molybdenum mines being put on care and maintenance, largely offset by higher DD&A from Mount Milligan Mine due to significantly higher gold sales volume in the fourth quarter of 2015.

Lower-of-cost-or-market/net realizable value product inventory write downs within DD&A for the three months ended December 31, 2015 and 2014 were as follows:



	Three Months Ended December 31,
	2015		2014
US Operations Molybdenum	$	0.1	$	0.2
Canadian Operations Molybdenum	—		1.1
	$	0.1	$	1.3

General and Administrative Expense

General and administrative expense in the fourth quarter of 2015 was $4.7 million compared to $6.6 million in the fourth quarter of 2014. Quarter over quarter, the decrease in general and administrative expense was primarily due to lower salaries and benefits expense. General and administrative expense for the fourth quarter of 2015 and 2014 included $0.4 million and $0.6 million, respectively, in stock-based compensation expense. In accordance with US GAAP, stock-based compensation is included in the specific statement of operations categories that include the compensation costs of the employees, officers and directors for which the stock-based award applies.

Exploration Expense

Exploration expense in the fourth quarter of 2015 and 2014 was $2.4 million and $0.3 million, respectively. Quarter over quarter, the increase in exploration expense is due primarily to $2.2 million in exploration expense, incurred in the fourth quarter of 2015, relating to an exploration project in south-central British Columbia known as "IKE".

Asset Impairments

Our impairment analysis did not result in any long-lived asset impairments during the fourth quarter of 2015. During 2014, we wrote-off the property, plant and equipment and materials and supplies assets of our US and Canadian molybdenum operations to their overall liquidation values.

The following table sets forth the write downs of property, plant, and equipment and development assets, mineral reserves and materials and supplies inventory for the periods presented:

	$	—	$	104.8	$	194.9

Our asset impairment charges in the fourth quarter of 2014 were primarily related to Endako Mine and was recorded as a result of our decision to suspend operations. Additionally, during the fourth quarter of 2014 we recorded impairments of our exploration properties given the expected and continued weakness in commodity prices.

Our asset impairment charges during the fourth quarter of 2013 were primarily related to TC Mine and Endako Mine. TC Mine assets were impaired as a result of our decision to put TC Mine on care and maintenance while Endako Mine asset impairments were a result of an update to Endako Mine molybdenum reserves using a price of $10 per pound of molybdenum oxide compared to $12 per pound used previously.

Interest and Finance Fees

Interest and finance fees were $21.1 million in the fourth quarter of 2015 compared to $22.9 million in the fourth quarter of 2014. Quarter over quarter, the decrease in interest and finance fees was due to the repurchase and retirement of certain of our Senior Notes as discussed in Note 9 within Item 8 for further discussion. In the fourth quarter of 2015 and 2014, we capitalized $0.6 million and $0.8 million, respectively of interest and amortization of debt issuance costs. We capitalize interest expense allocable to the cost of developing mining properties and to construct new facilities until assets are ready for their intended use. Capitalized interest is amortized using the units-of-production method over the estimated life of the ore body based on recoverable quantities to be mined from proven and probable reserves.

Gain from Debt Extinguishment

We did not have any gain from debt extinguishment in the fourth quarter of 2015. Gain from debt extinguishment of $2.1 million in the fourth quarter of 2014 was due to the retirement of certain Senior Notes repurchased in the open market at less than their outstanding principal amount net of the effect of writing off deferred financing costs associated with such Senior Notes. There was no such repurchase in the fourth quarter of 2015. Please refer to Note 9 in Item 8 for further discussion.

Foreign Exchange Gains and Losses

We recognized $28.3 million and $35.3 million of foreign exchange losses in the fourth quarter of 2015 and 2014, respectively. These non-cash foreign currency losses were primarily unrealized and related to intercompany notes that were entered into as part of a strategy to manage cash balances to fund our operations and provide future tax benefits. Quarter over quarter the decrease in foreign exchange losses was primarily due to a net decrease in borrowings offset by the relative weakening of the C$ against the US$. The rate at which the intercompany notes were revalued was US$1.00 = C$1.38 at December 31, 2015, compared to US$1.00 = C$1.16 at December 31, 2014.

The foreign exchange losses in the fourth quarter of 2015 and 2014 included approximately $1.3 million of realized losses primarily related to forward currency contracts and $2.0 million in realized gains primarily on other operating items.

Table of Contents

Income and Mining Tax Benefit

For the fourth quarter of 2015, we had a tax benefit of $58.9 million compared to a benefit of $16.4 million for the fourth quarter of 2014. The primary difference in the effective tax rate between the two periods is driven by the change in our valuation allowances in the fourth quarter of 2015 due to a change in the legal structure as a result of the current operational status of our molybdenum mines in order to optimize the use of our tax attributes.

As a result of a change in the legal structure in 2015, which will facilitate a future consolidation of Canadian tax reporting entities, our valuation allowances changed. The change had a favorable impact on the amount of our deferred taxes that we expect will be realized in the future, resulting in the reversal of $51.6 million of valuation allowances associated with those deferred tax assets.

As a result of the impairments of our exploration stage properties in the fourth quarter of 2014, we recognized a tax benefit of $7.0 million through a reduction of deferred tax liabilities. However, the asset impairment for Endako Mine and TC Mine assets for the fourth quarter of 2014 did not have a tax impact due to a valuation allowance. This yielded a net effective tax rate of 6.7% on $104.8 million of asset impairments.

The tax benefit for the three months ended December 31, 2015 was decreased due to a $1.0 million loss on foreign exchange recorded as a component of deferred tax benefit. The tax benefit for the three months ended December 31, 2014 was also increased due to a $0.5 million gain on foreign exchange recorded as a component of deferred tax benefit.

Three Years Ended December 31, 2015

Net Loss

Net loss for the year ended December 31, 2015 was $134.9 million, or $0.62 per diluted share, compared to a net loss of $124.2 million, or $0.64 per share, for the year ended December 31, 2014 and a net loss of $215.0 million, or $1.26 per share, for the year ended December 31, 2013.

The net loss for 2015 was primarily the result of non-cash foreign currency losses of $168.4 million primarily on intercompany notes, and interest and finance fee expense of $87.3 million, partially offset by an income and mining tax benefit of $87.5 million and operating income of $31.0 million.

The net loss for 2014 was primarily the result of non-cash asset impairments of $104.8 million, non-cash foreign currency losses of $99.8 million primarily on intercompany notes and interest and finance fee expense of $92.3 million partially offset by an income tax benefit of $21.7 million.

The net loss for 2013 was primarily the result of $194.9 million in non-cash asset impairments, non-cash foreign currency losses of $70.8 million primarily on intercompany notes and interest and finance fee expense of $24.1 million, partially offset by an income tax benefit of $63.4 million.

The net loss for the years ended December 31, 2015, 2014 and 2013 also included product inventory write downs of $15.8 million, $25.5 million and $57.8 million, respectively.

Non-GAAP adjusted net loss for the year ended December 31, 2015 was $49.8 million, or $0.23 per diluted share, non-GAAP adjusted net income for the year ended December 31, 2014 was $54.6 million, or $0.25 per diluted share, and non-GAAP adjusted net loss for the year ended December 31, 2013 was $5.0 million, or $0.03 per diluted share. See "Non-GAAP Financial Measures" below for the definition and reconciliation of adjusted net (loss) income.

Revenue

Revenues for the year ended December 31, 2015 were $494.1 million, down 38.8% compared to 2014, primarily due to our molybdenum mines being placed on care and maintenance partially offset by slightly higher revenues from Mount Milligan Mine.

During 2015, we sold 76.5 million pounds of payable copper at an average realized sales price of $2.28 per pound and 221,902 ounces of payable gold at an average realized sales price of $950 per ounce for total revenues of $360.9 million compared to the sale of 64.7 million pounds of payable copper at an average realized sales price of $3.02 per pound and 172,741 ounces of gold at an average realized sales price of $1,002 per ounce for total revenue of $350.7 million during 2014.

Table of Contents

During 2015, we made 15 shipments to MTM Customers, recognized 15 sales and received 14 provisional payments. Additionally, in 2015, we received 14 final settlement payments for 14 shipments, five of which related to 2014 shipments. During 2014, we made 12 shipments to MTM Customers, recognized 12 sales and received provisional payments for 12 shipments and final settlement payments for eight shipments, one of which related to 2013. During 2013, we made one shipment to MTM Customers, recognized one sale and received a provisional payment for this shipment.

Revenues for the year ended December 31, 2014 were $806.7 million, up 85.7% compared to 2013. Year over year, the increase in revenue was due to 12 copper and gold sales in 2014 compared to one sale in 2013.

During 2015, 2014 and 2013, we sold 12.1 million pounds, 36.6 million pounds and 36.5 million pounds of molybdenum, respectively, of which 4.0 million pounds, 28.5 million pounds and 31.5 million pounds, respectively, were from our molybdenum mines. The average realized sales priced for molybdenum for the years ended December 31, 2015, 2014 and 2013 were $8.55 per pound, $12.06 per pound and $10.97 per pound respectively.

Operating Expenses

Operating expenses in 2015 were $305.6 million, down 41.7% compared to 2014. Year over year, the decrease in operating expenses was primarily the result of TC Mine and Endako Mine being placed on care and maintenance as well as lower operating expenses at Mount Milligan Mine due to favorable Canadian foreign exchange rates. Additionally, year over year, the favorable impact of foreign exchange rates on operating expenses at Mount Milligan Mine was partially offset by temporary secondary crushing costs and mill maintenance costs (related to various operational issues) in addition to the increase in operating expenses in 2015 from the sale of copper and gold inventory produced in 2014 at higher cost.

Operating expenses in 2014 were $523.8 million, up 59.6% compared to 2013. The increase in operating expenses in 2014 compared to 2013 was primarily the result of operating Mount Milligan Mine for an entire year, which was partially offset by a decrease in lower-of-cost-or-net realizable value product inventory write-downs primarily due to the start-up of the Mount Milligan Mine in 2013.

Lower-of-cost-or-market/net realizable value product inventory write downs within operating expenses for 2015, 2014 and 2013 were as follows:



	Years Ended December 31,
	2015		2014		2013
Copper-Gold	$	—	$	—	$	20.2
US Operations Molybdenum	13.7		2.1		—
Canadian Operations Molybdenum	1.4		20.4		24.1
	$	15.1	$	22.5	$	44.3

Molybdenum product inventory write downs in 2015 were primarily related to third party purchased product and were the result of declining prices. Molybdenum product inventory write downs for the Canadian Operations Molybdenum segment in 2014 were primarily the result of higher cost production from Endako Mine due to lower than anticipated ore grades and recoveries. Product inventory write downs for the US Operations Molybdenum segment in 2014 were primarily the result of higher cost of production from TC Mine in the fourth quarter of 2014 as we processed stockpiled ore from Phase 7, which resulted in higher unit cash costs in relation to molybdenum market prices. Canadian Operations Molybdenum product inventory write downs in 2013 were primarily due to various operational issues experienced in the first half of 2013, together with materials and supplies surplus and obsolete inventory write downs in the fourth quarter of 2013, which resulted in higher unit cash costs in relation to molybdenum market prices. Copper-gold product inventory write downs in 2013 were the result of the start-up of the mine, with higher unit cash costs in relation to copper and gold market prices.

The non-GAAP financial measures of cash cost per pound produced from our Copper-Gold operations for 2015, 2014 and 2013 were as follows:

For Copper-Gold, 2015 unit cash costs were lower when compared to 2014 due primarily to higher production and favorable exchange rates in 2015. Additionally, on a by-product basis, 2015 copper cash costs were lower due to higher gold sales in 2015. For Copper-Gold, unit cash costs for 2014 were significant lower when compared to 2013 since 2014 unit cash costs reflected production for the full year whereas the 2013 unit cash costs reflected production for the fourth quarter of 2013 only, due to the start-up of Mount Milligan Mine.

During 2015 TC Mine and Endako Mine were on care and maintenance/suspended operations.

DD&A

DD&A in 2015 was $98.6 million, a decrease of 1.3%, compared to 2014. Year over year DD&A decreased primarily due to significantly lower sales of molybdenum inventory in 2015, absence of ongoing other DD&A for TC Mine and our share of Endako Mine, as a result of idle mining operations and reduced lower-of-cost-or-market/net realizable value product inventory write downs, largely offset by higher DD&A from Mount Milligan Mine due to significantly higher copper and gold sales volume in 2015.

DD&A in 2014 was $99.9 million, an increase of 92.5%, compared to 2013. Year over year, the increase in DD&A was primarily attributable to the addition of a full year of DD&A at Mount Milligan Mine, which was partially offset by reduced lower-of-cost-or-market product inventory write downs and lower DD&A at TC Mine and Endako Mine due to the non-cash write-downs of the property, plant and equipment at TC Mine and Endako Mine in the fourth quarter of 2013, which reduced the carrying value and depreciable base of our molybdenum assets (or our share of the carrying value and depreciable base of the assets, in the case of Endako Mine) and a lower volume of molybdenum pounds sold from our mines compared to 2013.

Lower-of-cost-or-market/net realizable value product inventory write downs within DD&A for 2015, 2014 and 2013 were as follows:

General and Administrative Expense

General and administrative expense in 2015 was $19.8 million compared to $23.5 million and $21.6 million in 2014 and 2013, respectively. General and administrative expense decreased in 2015 from 2014 primarily due to a $2.3 million decrease in salaries and benefits expense and a $1.0 million decrease in consulting services. General and administrative expenses were higher in 2014 compared to 2013 primarily due to a $1.8 million increase in compensation expense in connection with severance costs and bonuses, a $1.3 million increase in tax consulting and audit services which were partially offset by other lower consulting fees. General and administrative expense in 2015, 2014 and 2013 included $3.4 million, $3.6 million and $3.3 million, respectively, of non-cash stock-based compensation expense.

Exploration Expense

Exploration expense in 2015 was $2.5 million compared to $0.9 million in 2014 and $1.4 million in 2013. Year over year, the increase in exploration expense was due primarily to $2.2 million in exploration expense in 2015 relating to the IKE project.

Exploration expense in 2014 was $0.9 million compared to $1.4 million in 2013. The 2014 expenses were primarily comprised of mineral tenure payments of $0.5 million relating to the Berg and Maze Lake properties and $0.4 million relating to exploration activities primarily at Mount Milligan Mine. The 2013 expenses were primarily $0.6 million in mineral tenure payments for the Berg property, exploration drilling activities at TC Mine, Endako Mine and Mount Milligan Mine of $0.2 million, and $0.6 million for property payments on the Davidson property.

Asset Impairments

Our impairment analysis did not result in any long-lived asset impairments during 2015. As discussed below, during 2014, we wrote-off the property, plant and equipment and materials and supplies assets of our US and Canadian molybdenum operations to their overall liquidation values.

Table of Contents

The following table sets forth the write downs of property, plant, and equipment and development assets, mineral reserves and materials and supplies inventory for the periods presented:

	$	—	$	104.8	$	194.9

Our 2014 asset impairment charges were primarily related to Endako Mine and was recorded as a result of our decision to suspend operations. Additionally, during 2014 we recorded impairments of our exploration properties given the expected and continued weakness in commodity prices.

Our 2013 asset impairment charges were primarily related to TC Mine and Endako Mine. TC Mine assets were impaired as a result of our decision to put TC Mine on care and maintenance while Endako Mine asset impairments were a result of an update to Endako Mine molybdenum reserves using a price of $10 per pound of molybdenum oxide compared to $12 per pound used previously.

Interest and Finance Fees

Interest and finance fees were $87.3 million for the year ended December 31, 2015 compared to $92.3 million for the year ended December 31, 2014. Year over year, the decrease in interest and finance fees was due to the repurchase and retirement of certain of our Senior Notes as discussed in Note 9 within Item 8.

Interest and finance fees of $87.3 million in 2015 were composed of $83.0 million in interest and finance fees on senior secured and unsecured notes and tMEDS, $4.2 million in interest on mobile mining equipment loans and $0.1 million in debt issuance cost amortization and commitment fees. In 2015, we capitalized interest and debt issuance costs totaling $1.7 million. As of December 31, 2015, all obligations with respect to the tMEDS had been satisfied and no tMEDS remain outstanding.

Interest and finance fees of $92.3 million in 2014 were composed of $87.0 million in interest and finance fees on our Senior Notes and tMEDS, $5.1 million in interest on mobile mining equipment loans and $0.2 million in debt issuance cost amortization and commitment fees. In 2014, we capitalized interest and debt issuance costs totaling $4.1 million.

Interest and finance fees of $24.1 million in 2013 were composed of approximately $21.7 million in interest and finance fees on our Senior Notes and tMEDS, $2.2 million in interest on mobile mining equipment loans and $0.2 million in debt issuance cost amortization and commitment fees. Beginning in September 2013, in conjunction with the start-up phase at Mount Milligan, we ceased capitalizing a large portion of incurred interest and debt issuance costs related to our senior secured and unsecured notes, tMEDS and equipment financing facility. In 2013, we capitalized interest and debt issuance costs totaling $75.2 million.

In 2015, we made cash interest payments of $85.1 million related to our Senior Notes, tMEDS and equipment financing facility. In 2014 and 2013 we made cash interest payments of $91.3 million and $81.8 million, respectively related to our senior unsecured notes, tMEDS, and equipment financing facility.

Loss (Gain) from debt extinguishment

Loss from debt extinguishment in 2015 was $2.8 million compared to a gain from debt extinguishment of $1.6 million in 2014. The loss and gain in 2015 and 2014, respectively, were due to the retirement of certain Senior Notes, net of the effect of writing off deferred financing costs associated with such Senior Notes.

Table of Contents

Other

Other income in 2015 was $4.9 million compared to $8.1 million for 2014 and $1.1 million in 2013. Other income in 2015 related to mark-to-market adjustments of which $7.6 million was realized income and $2.7 million was unrealized loss, both of which were related to commodity price hedges. Other income in 2014 included receipt of a settlement associated with interest on a 2010 state tax refund and $4.7 million in mark-to-market income related to copper and gold commodity price hedges, of which $2.0 million was realized and $2.7 million was unrealized. Other income in 2013 was primarily $0.8 million of miscellaneous income.

Foreign Exchange Gains and Losses

During 2015, 2014 and 2013 we recognized foreign exchange losses of $168.4 million, $99.8 million and $70.8 million respectively.

These non-cash foreign currency losses were primarily unrealized and related to intercompany notes that were entered into as part of a strategy to manage cash balances to fund our operations and provide future tax benefits. The increase in foreign exchange losses from 2014 to 2015 and 2013 to 2014 reflects the continued weakening of the C$ against the US$. The foreign exchange rate was US$1.00 = C$1.38 at December 31, 2015 compared to US$1.00 = C$1.16 at December 31, 2014 and US$1.00 = C1.06 million at December 31, 2013.

The foreign exchange losses in 2015, 2014 and 2013 included approximately $3.5 million of realized losses primarily related to forward currency contracts, $1.5 million in realized gains on other operating items and $0.4 million in realized losses on other operating items, respectively.

Income and Mining Tax Benefit

We had a tax benefit of $87.5 million in 2015 compared to a benefit of $21.7 million in 2014 and a benefit of $63.4 million in 2013. The primary difference in the effective tax rate between the three years is driven by the change in our valuation allowances due to the legal structure changes and asset impairments, as discussed previously.

As a result of the asset impairments of our exploration properties in 2014, we recognized a tax benefit of $7.0 million through a reduction of deferred tax liabilities. The asset impairments for Endako Mine and TC Mine assets for 2014 did not have a tax impact due to a valuation allowance. This yielded a net effective tax rate on impairments of 6.7% on $104.8 million of asset impairments.

As a result of the asset impairments in the US for 2013, we recognized a tax benefit of $47.7 million through a reduction of deferred tax liabilities, offset with a valuation allowance impact associated with the asset impairments of $1.5 million expense. The asset impairment for Endako Mine in 2013 did not have a tax impact due to a valuation allowance. This yielded a net effective tax rate of 23.7% on $194.9 million of asset impairments.

The tax benefit for the year ended December 31, 2015 was also decreased by $3.4 million due to a loss on foreign exchange recorded as a component of deferred tax benefit. The tax benefit for the year ended December 31, 2014 was also increased by $7.4 million due to a change in various tax positions and by $1.1 million due to a gain on foreign exchange recorded as a component of deferred tax benefit. The tax benefit for the year ended December 31, 2013 was also decreased due to the change in the British Columbia provincial income tax rate and a $0.5 million loss on foreign exchange recorded as a component of deferred tax benefit.

⁽¹⁾	Payable production for copper and gold reflects estimated metallurgical losses resulting from handling of the concentrate and payable metal deductions, subject to metal content, levied by smelters. The current payable percentage applied is approximately 95.0% for copper and 96.5% for gold, which may be revised on a prospective basis after sufficient history of payable amounts is determined.


⁽²⁾	See “Non-GAAP Financial Measures” for the definition and reconciliation of these non-GAAP measures.

Copper and Gold Production and Cash Costs

For the fourth quarter of 2015 compared to the fourth quarter of 2014, there was a 7.8% increase in concentrate production (dry tonnes), an 8.0% increase in payable copper production, a 42.2% increase in payable gold production and a 10.0% increase in mill throughput. For the year ended December 31, 2015 compared to the year ended December 31, 2014, there was a 12.2% increase in concentrate production (dry tonnes), a 10.6% increase in payable copper production, a 22.8% increase in payable gold production and a 12.9% increase in mill throughput.

Non-GAAP unit cash costs for the fourth quarter of 2015 compared to the fourth quarter of 2014 were $0.79 per pound compared to $1.16 per pound of copper on a by-product basis, respectively, $1.39 per pound compared to $1.88 per pound on a co-product basis for payable copper, respectively, and $463 per ounce compared to $506 per ounce on a co-product basis for payable gold, respectively. By-product cash costs for the quarter ended December 31, 2015 were favorably impacted by higher ounces of gold sold in the fourth quarter of 2015 compared to the fourth quarter of 2014.

Table of Contents

Non-GAAP unit cash costs for 2015 compared to 2014 were $0.55 per pound compared to $1.15 per pound on a copper by-product basis, respectively, $1.55 per pound compared to $1.97 per pound on a co-product basis for payable copper, respectively, and $478 per ounce compared to $525 per ounce on a co-product basis for payable gold, respectively. By-product cash costs for 2015 as compared to 2014 were favorably impacted by higher ounces of gold sold in 2015 than 2014.

Non-GAAP unit cash costs for 2014 compared to 2013 were $1.15 per pound compared to $7.76 per pound on a copper by-product basis, respectively, $1.97 per pound compared to $5.40 per pound on a co-product basis for payable copper, respectively, and $525 per ounce compared to $1,468 per ounce on a co-product basis for payable gold, respectively. By-product cash costs for 2014 as compared to 2013 were favorably impacted by significantly higher ounces of gold sold in 2014 than 2013.

Operating expenses were positively impacted by favorable foreign exchange rates, as the US$ strengthened against the C$ in 2015 compared to 2014. The average foreign exchange rate was US$1.00 = C$1.34 for the fourth quarter of 2015 compared to US$1.00 = C$1.14 for the fourth quarter of 2014, resulting in a favorable impact on operating expenses of approximately $5.4 million in the fourth quarter of 2015. The average foreign exchange rate was US$1.00 = C$1.28 for 2015 compared to US$1.00 = C$1.10 for 2014 resulting in a favorable impact on operating costs of approximately $25.0 million. The average foreign exchange rate was US$1.00 = C$1.10 for 2014 and US$1.00 = C$1.03 for 2013 resulting in a favorable impact on operating expenses of approximately $12.8 million.

Copper and Gold Sold

During the three months ended December 31, 2015 compared to the three months ended December 31, 2014, copper sales volumes increased by 4.2% and gold sales volumes increased by 33.1%. For copper, the increased sales volumes were more than offset by a 30.2% lower average realized sales price which resulted in a decrease in copper sales revenue quarter over quarter. For gold, sales revenue increased quarter over quarter, with the increase in sales volumes being only partially offset by a 7.1% lower average realized gold sales price.

During 2015 copper sales volumes increased by 18.3% and gold sales volumes increased by 28.5% when compared to 2014. We made 15 shipments and recognized 15 sales in 2015 compared to 12 shipments and 12 sales in 2014. For copper, the increase in 2015 sales volumes were more than offset by a 24.5% lower average realized sales price resulting in lower copper sales revenues in 2015 compared to 2014. For gold, the increase in 2015 sales volumes were only partially offset by a 5.2% lower average realized sales price for gold, resulting in higher gold sales revenues in 2015 compared to 2014.

The average realized prices for copper and gold for the quarter and year ended December 31, 2015 were impacted by falling metals prices which resulted in negative adjustments to the final settlement of certain provisional payments together with negative mark-to-market adjustments for prior period provisional payments not yet final. See “Non-GAAP Financial Measures” for the definition and reconciliation of the non-GAAP average realized sales prices.

During 2014, we made 12 shipments to MTM Customers and recognized 12 sales whereas during 2013, we made one shipment to MTM Customers and recognized one sale. As a result, copper sales volumes increased by 2,209.6% and gold sales volumes increased by 3,017.5% in 2014 as compared to 2013.

Cash Capital Expenditures

During the three months ended December 31, 2015, we made C$15.2 million of cash capital expenditures for Mount Milligan Mine, consisting of C$2.9 million for site preparation, pre-construction and concrete work and C$2.9 million for engineering work, both related to the permanent secondary crusher, C$7.1 million for the tailings storage facility and C$2.3 million for ongoing operational capital. During 2015, we made C$70.0 million of cash capital expenditures for Mount Milligan Mine, consisting of C$3.8 million for site preparation, pre-construction and concrete work and C$6.3 million for engineering work, both related to the permanent secondary crusher, C$23.7 million for tailings storage facility, C$16.8 million for ongoing operational capital, C$16.0 million for the one-time settlement of certain Mount Milligan Mine construction and development claims and C$3.4 million related primarily to the payment of accruals from 2014.

US Molybdenum Operating Activities

As previously disclosed, the discussion below does not reflect TC Mine due to its care and maintenance status as of January 1, 2015.

Table of Contents

Langeloth Facility

Operating results for the Langeloth Facility represent activities related to the roasting and processing of third-party concentrate and other metals at the Langeloth Facility. For 2015 and 2014 Langeloth’s Facility costs associated with the roasting and processing of TC Mine and Endako Mine products are excluded from Langeloth’s Facility costs and are included in each mine's respective operating results. However, the molybdenum pounds and the costs for the molybdenum beneficiation circuit at TC Mine, treating molybdenum concentrates to supplement the concentrate feed we source directly for our Langeloth facility, are included in the Langeloth Facility operating results.

The following is a summary of the Langeloth Facility's operating results for the three months ended December 31, 2015 and 2014 and years ended December 31, 2015, 2014 and 2013:



	Three Months Ended December 31,				Years Ended December 31,
(Unaudited)	2015		2014		2015		2014		2013
Operational Statistics
Molybdenum sold from purchased product (000's lb)	2,410		2,376		8,164		8,061		5,054
Realized price on molybdenum sold from purchased product ($/lb)	$	6.02	$	9.16	$	7.37	$	12.02	$	11.35
Toll roasted and upgraded molybdenum processed (000's lb)	2,607		80		17,183		726		3,782
Roasted metal products processed (000's lb)	650		748		7,532		9,938		17,784

Molybdenum sold from third-party purchased molybdenum concentrate increased for the quarter and year ended December 31, 2015, as compared to the same periods in 2014 primarily due to the shift in our Langeloth business model. Quarter over quarter and year over year, the decrease in average realized sales price on molybdenum sold from purchased product is primarily due to falling molybdenum prices.

Molybdenum sold from purchased product for the year ended December 31, 2014 was up 59.5% from 2013 primarily as a result of lower production and sales from our own molybdenum mines in 2014. The average realized sales price was $12.02 per pound in 2014 compared to $11.35 per pound in 2013, primarily due to changes in the market price of molybdenum oxide during 2014.

The volume of toll roasted and upgraded molybdenum processed during the fourth quarter of 2015 and year ended December 31, 2015 was up 3,158.8% and 2,266.8%, respectively, compared to the same periods in 2014, primarily due to the shift in our Langeloth business model.

The volume of toll roasted molybdenum processed during 2014 decreased 80.8% compared to 2013 primarily due to lower capacity for third-party material due to higher volume of material processed from our own molybdenum mines in 2014 compared to 2013.

The volume of roasted metal products processed during the quarter and year ended December 31, 2015 decreased 13.1% and 24.2%, respectively, compared to the same periods in 2014 due to decreased customer demand and the lack of available material. The volume of roasted metal products decreased 44.1% in 2014 compared to 2013 due to decreased customer demand and decreased available material.

Liquidity and Capital Resources

Our financial position was as follows:



	At December 31,
	2015		2014
Cash and cash equivalents	$	176.8	$	265.6
Accounts receivable, including related party receivables	$	52.7	$	46.1
Accounts payable	$	72.0	$	93.1
Current portion of debt, including equipment financings	$	25.6	$	26.7
Total working capital	$	174.7	$	286.2
Total debt, including equipment financings	$	884.6	$	944.7

Table of Contents

We monitor our positions with, and the credit quality of, the financial institutions and companies in which we invest our cash and cash equivalents. We manage our credit risk from accounts receivable through our collection activities. As of the date of this Annual Report on Form 10-K, we have not experienced any material delinquencies regarding the collection of accounts receivable.

During 2015, our debt and liquidity positions were primarily affected by the following:


•	Cash generated by operating activities of $37.4 million which primarily reflects provisional payments received for 14 of the 15 shipments of concentrate (the remaining 2015 provisional payment of $23.8 million was received in January 2016), and $19.8 million of tax refunds during 2015;


•	Capital expenditures of $61.3 million, primarily related to our Mount Milligan Mine ongoing operations, engineering, site-preparation and pre-construction work for the permanent secondary crusher and the payment of certain vendor claims related to the construction and development of Mount Milligan Mine; and


•	Principal payments of $69.6 million primarily related to the repayment of equipment financings and repurchases of certain of our 2017, 2018 and 2019 Notes.

We monitor our exposure to the prices of our products as well as the currencies in which we operate. During 2015, we entered into hedges to manage exposure to fluctuations in the prices of copper and gold and also purchased gold to satisfy our obligations under the Gold Stream Arrangement. During 2015, we also entered into hedges to manage exposure to the potential strengthening of the Canadian dollar against the US dollar. See Note 6 within Item 8 for further discussion.

During 2015 we repurchased and retired $41.4 million of 2017, 2018 and 2019 Notes, reducing future interest payments by approximately $11.6 million. During 2014 we repurchased and retired $25.7 million of 2018 and 2019 Notes, in open market transactions, reducing future interest payments by approximately $9.9 million. We may from time to time redeem, retire and/or purchase more outstanding debt, depending upon prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. However, there can be no assurance that we will take any of these actions.

As previously disclosed, we believe that estimated cash flow from our Mount Milligan Mine, together with cash on hand as of December 31, 2015, will provide sufficient liquidity to fund our planned capital expenditures, working capital needs and scheduled debt and interest payments until our outstanding Senior Notes come due, beginning in December 2017. This liquidity outlook is based on the following assumptions: (i) estimated copper and gold production and operating and capital costs for fiscal years 2016 and 2017 based on our current mining plan; (ii) spot prices ranging from$2.00 to $2.40 per pound for copper; (iii) spot prices ranging from $1,000 to $1,100 per ounce for gold; (iv) foreign exchange rates ranging from US$1.00 = C$1.28-$1.35; and (v) financial assurance obligations, including assurances related to our reclamation obligations, substantially consistent with our current obligations. On February 22, 2016, the spot price for copper was $2.13 per pound and the closing price for gold was $1,211 per ounce and the foreign exchange rate was US$1.00 = C$1.37. Refer to Part I, Item 1.A “Risk Factors” for a discussion of risks and uncertainties that could adversely impact the assumptions underlying our liquidity outlook and affect our liquidity in the short and long term.

As previously noted in Highlights and Overview, copper and gold prices, the operating performance of our Mount Milligan Mine, the US$ to C$ foreign exchange rate and the scheduled maturities of our outstanding Senior Notes are the critical drivers of our liquidity and credit quality.

The following table summarizes the scheduled maturities and interest rates of our Senior Notes as of December 31, 2015:




Senior Notes ⁽¹⁾	Balance as December 31, 2015 (in millions)		Maturity	Interest Rate
2017 Notes	$	315.8	December 1, 2017	9.75	%
2018 Notes	334.1		June 1, 2018	7.375	%
2019 Notes	183.0		May 1, 2019	12.5	%
Total	$	832.9

⁽¹⁾Refer to Note 9 in Item 8 for additional information and definitions. All three series of Senior Notes are guaranteed on a senior basis by substantially all of our subsidiaries. The 2017 Notes are secured by a first priority lien (subject to permitted liens) on substantially all of our assets while the 2018 Notes and 2019 Notes are unsecured. The indentures governing the Senior Notes contain certain restrictive covenants but do not contain any maintenance covenants with respect to our financial performance.

The significant decline in copper prices in 2015, and the continuing and expected weakness in the base metals market has materially negatively impacted our ability to generate sufficient cash flow from operations to fully repay our outstanding Senior Notes when they come due, and, as a result, our credit quality has declined and our long-term liquidity has been adversely affected. These constraints on our liquidity in the long term limit our ability in the near term to make capital investments in our business, take advantage of opportunities for strategic growth, secure funding for capital projects on reasonable terms, and secure needed working capital to withstand prolonged downturns in the mining industry.

In November, 2015, we announced that we have engaged financial advisors to assist us in evaluating strategic and financial alternatives available to us, including debt refinancing and restructuring, new capital transactions and asset sales, to de-lever the balance sheet and complete a capital refinance/restructure in order to insure that we can continue to operate with sufficient liquidity in the longer term while providing a platform for future opportunities. In connection with a debt restructuring or refinancing, we may seek to convert a significant portion of our outstanding debt to equity, including the exchange of debt for shares of our common stock. In addition, we may seek to reduce our cash interest cost and/or extend debt maturity dates by negotiating the exchange of outstanding debt for new debt with modified terms or other measures. While we anticipate engaging in active dialogue with our creditors and others, at this time, we are unable to predict the outcome of such discussions, the outcome of any strategic transactions that we may pursue or whether any such efforts will be successful. In addition, our ability to complete new capital and other transactions efficiently depends on a number of factors, including the state of global commodity, credit and equity markets, interest rates, credit spreads, and our credit ratings. If we are unable to refinance or restructure our outstanding Senior Notes, complete new capital transactions or obtain additional financings on acceptable terms or at all, we will face significant liquidity challenges as we approach the maturity of our outstanding Senior Notes. Refer to Part I, Item 1.a “Risk Factors” for a discussion of additional risks relating to our liquidity.

Additionally, as of December 31, 2015, we have provided the appropriate regulatory authorities in the US and Canada with approximately $72.5 million in reclamation financial assurance in the form of surety bonds for our share of mine closure obligations in the jurisdictions in which we operate. As of December 31, 2015, the surety bonds required cash collateral of $10.0 million. Any perceived challenges to our liquidity in the short or long term could cause regulatory authorities and contractual counterparties to require additional financial assurances with respect to our obligations to them. To the extent that the value of any security provided to regulatory authorities is or becomes insufficient to cover the amount of financial assurance we are required to post, we would be required to replace or supplement the existing security with more expensive forms of security, which might include cash deposits, which would have an adverse effect on our liquidity. Refer to Part I, Item 1.A “Risk Factors” for additional discussion.

Operating Cash Flows

Cash generated by operating activities was $37.4 million, $184.8 million and $44.8 million for the years ended December 31, 2015, 2014 and 2013 respectively. The decrease in cash flow from operations from 2014 to 2015 is due primarily to falling metal prices, and our molybdenum mines being placed on care and maintenance. Cash flow from operations in 2015 benefited from $19.8 million of tax refunds, which partially offset the lower molybdenum sales and falling metal prices, discussed above. Additionally, for the years ended December 31, 2015 and 2014 cash flow from operations was unfavorably impacted by $0.9 million and benefited by $27.9 million, respectively in net payables related to the Gold Stream Arrangement.

The increase in cash flow from operations from 2013 to 2014 was primarily a result of a full year of copper and gold sales at Mount Milligan Mine net of operating expenses. Mount Milligan Mine commenced operations in the fourth quarter of 2013. For the years ended December 31, 2014 and 2013 cash flow from operations benefited by $27.9 million and $0.6 million, respectively in net payables related to the Gold Stream Arrangement for undelivered ounces.

Investing Activities

Cash used in investing activities was $55.7 million, $93.9 million and $449.1 million for the years ended December 31, 2015, 2014 and 2013 respectively. The decrease in cash used in investing activities from 2014 to 2015 is primarily related to the completion of the construction and development of Mount Milligan Mine. During 2015 cash used in investing activities consisted of $61.3 million primarily related to Mount Milligan Mine ongoing operating capital, engineering, site preparation and pre-construction work on the permanent secondary crusher and the payment of certain vendor claims related to the construction and development of Mount Milligan Mine, offset by $7.2 million in release of restricted cash related to Mount Milligan Mine construction. During 2014, we spent $82.1 million on property, plant, equipment and development expenditures primarily related to the construction of the permanent operations residence at Mount Milligan Mine, the construction and development of the Mount Milligan project (which was primarily related to the payment of accruals as of December 31, 2013) and operating capital. During 2013, we spent $428.9 million on property, plant, equipment and development expenditures primarily related to the construction and development of Mount Milligan Mine. Payments of capitalized interest primarily related to the construction and development of Mount Milligan Mine were $1.8 million, $9.1 million and $74.7 million during the years ended December 31, 2015, 2014 and 2013, respectively.

Table of Contents

During 2015, 2014 and 2013 we received reclamation refunds of $0.2 million, $7.1 million and $28.1 million, respectively and posted cash collateral of nil, $10.0 million and $7.0 million, respectively against existing surety bonds.

Financing Activities

Summary of Financing Activities

Cash used in financing activities for 2015 and 2014 was $68.9 million and $55.8 million, respectively compared to cash generated by financing activities of $110.8 million in 2013. The increase in cash used in financing activities from 2014 to 2015 was due primarily to an increase in repurchases of our Senior Notes in 2015, as discussed above.

Cash used in financing activities during 2014 was $55.8 million compared to cash generated of $110.8 million for 2013. During 2014 our financing activities primarily consisted of repurchases of our senior secured and unsecured notes, whereas during 2013 we generated cash proceeds from the Gold Stream Arrangement and equipment financing transactions.

Gold Stream Arrangement

Pursuant to the Gold Stream Arrangement, we agreed to sell Royal Gold 52.25% of the refined gold production from Mount Milligan Mine for a total upfront payment of $781.5 million, plus $435 per ounce, or the prevailing market rate if lower than $435 per ounce, when the gold is delivered. In connection with the Gold Stream Arrangement, we received total cash payments of $781.5 million from Royal Gold.

The Gold Stream Arrangement restricts our ability to incur debt that is secured by the Mount Milligan Mine assets. Subject to the exceptions discussed below, we cannot incur debt that is secured by the Mount Milligan Mine assets in excess of $350.0 million until the earlier of the date upon which 425,000 ounces of refined gold have been sold and delivered to Royal Gold or the date upon which the aggregate dollar amount of the difference between the market price for the gold delivered to Royal Gold and the price actually paid by Royal Gold exceeds $280.0 million. Per the December 2014 amendment, discussed in Note 10 of Item 8, we are additionally permitted to pledge the Mount Milligan Mine assets to secure up to $50.0 million of hedging obligations incurred in connection with gold and copper production from Mount Milligan Mine, foreign currency exchange risk relating to Mount Milligan Mine and one or more corporate credit facilities utilized in connection with Mount Milligan Mine.

We must maintain the Record of Deposit during the term of the Gold Stream Arrangement wherein we reduce the $781.5 million total amount paid by Royal Gold by the difference between the current market price at the time of sale of refined gold to Royal Gold and $435 per ounce, multiplied by the amount of refined gold sold in such sale. If, at the end of the initial 50-year term of the agreement, the total deposit amount reflected in the deposit record has not been reduced to nil, we must pay to Royal Gold the remaining balance reflected in the deposit record. As of December 31, 2015, the remaining deposit per the Gold Stream Arrangement totaled $653.5 million. In the event of any default under the Gold Stream Arrangement, Royal Gold could require us to repay the outstanding deposit. The remaining Record of Deposit differs from the unrecognized deferred revenue for accounting purposes.

We receive provisional payments in cash, thus requiring that we purchase gold in order to satisfy the obligation to pay Royal Gold in gold. In order to hedge our gold price risk that arises when physical purchase and concentrate sales pricing periods do not match, we have and will continue to hedge our exposure to gold prices in connection with these provisional payments to Royal Gold. We currently have unsecured hedging lines in place with various banks in order to manage this exposure.

Royal Gold has a security interest in all of the Mount Milligan Mine assets until its total deposit amount has been reduced to nil. Royal Gold's security interest is subject to subordination to project or corporate financings by us, except that in such circumstances, Royal Gold retains a first priority interest in 52.25% of the refined gold from Mount Milligan. After the total deposit amount has been reduced to nil, Royal Gold's security will consist solely of its first priority interest in 52.25% of the refined gold. The cash received under the Gold Stream Arrangement is recorded as deferred revenue and classified as a liability on our Consolidated Balance Sheets. Mount Milligan Mine began delivering gold to Royal Gold in the fourth quarter of 2013. As such the deferred revenue is being recognized over the life of the mine based on the amount of gold delivered.

The proceeds received in the offering were $212.3 million, which were net of financing fees of $7.7 million. The net proceeds from the offering were used to fund the completion of Mount Milligan Mine and for general working capital purposes. On May 21, 2014, we commenced an offer ("Exchange Offer") to exchange any and all of the 8,340,000 then outstanding units of tMEDS for a number of shares of our common stock. On May 15, 2015, the prepaid share purchase contract portion of each outstanding tMED unit was automatically settled at the maximum settlement rate of 5.3879 shares of common stock. We issued a total of 6,105,210 shares of common stock in connection with such settlement. We also made the final installment payment on the amortizing note portion of each outstanding tMED unit, satisfying in full the principal and interest payments on the tMEDS. The mandatory settlement and final installment payment were made pursuant to the terms of the prospectus dated May 8, 2012, under which the tMEDS were offered in May 2012. As of December 31, 2015, all obligations with respect to the tMEDS had been satisfied and no tMEDS remain outstanding.

Caterpillar Equipment Financing Facility

On March 30, 2011, we entered into an equipment financing facility, as amended from time to time (the "Equipment Facility"), pursuant to which Caterpillar Financial Services Limited ("Caterpillar") agreed to underwrite up to $132.0 million in mobile fleet equipment financing for Mount Milligan Mine. Each borrowing under the Equipment Facility represents a capital lease and has a term of 48 or 60 months. Interest on the amounts borrowed under the Equipment Facility is payable at either floating or fixed rates, at our option. At the end of each 48 or 60 month lease period, we have the option to purchase the underlying equipment for a nominal sum. The Equipment Facility includes non-financial covenants, and as of December 31, 2015, we were in compliance with these covenants. Our ability to finance additional equipment under the Equipment Facility expired in September 2015 per the amended terms of the Equipment Facility agreement.

Endako Sale-Leaseback

During 2013, we entered into a sale-leaseback transaction with Caterpillar with respect to certain Endako Mine equipment. We received $5.3 million in cash from Caterpillar for the sale of this equipment, which was subsequently leased back, after an upfront down payment of $1.4 million. Interest payments are based on a fixed rate of 5.85%. On September 4, 2015, we assumed the lease for the remaining 25% of the equipment and subsequently transferred this equipment to Mount Milligan Mine. In connection with this transfer, we paid $0.3 million to Sojitz, our Endako Mine joint venture partner, for its 25% share of the fair value of the leased equipment and recognized an additional sale-leaseback obligation of $0.5 million. The agreement includes certain non-financial covenants, and as of December 31, 2015, we were in compliance with these covenants.

Mobile Mining Equipment Loans

On December 8, 2010, we executed an equipment financing agreement with Caterpillar in the amount of $12.8 million secured by six units of mobile mining equipment purchased by us during 2010. As of December 31, 2015, all obligations with respect to the mobile mining equipment loans had been satisfied.

Off-Balance Sheet Arrangements

As of December 31, 2015, we have commitments to purchase approximately 9.2 million pounds of molybdenum sulfide concentrate from 2016 to 2018 to be priced at the time of purchase. In addition, we have fixed-priced contracts, under which we have committed to sell approximately 368.9 thousand pounds of molybdenum in 2016 at an average market price of $7.08 per pound. Other than as set forth above, we had no other material off-balance sheet arrangements at December 31, 2015.

Non-GAAP Financial Measures

In addition to the consolidated financial statements presented in accordance with US GAAP, we use certain non-GAAP financial measures to assess our operating performance for the reasons described further below. These measures do not have standard meanings prescribed by US GAAP and may not be comparable to similar measures presented by other companies. The presentation of these measures is not intended to be considered in isolation from, as a substitute for, or as superior to, the financial information prepared and presented in accordance with US GAAP. In addition, these non-GAAP measures have limitations in that they do not reflect all of the amounts associated with the results of operations as determined in accordance with US GAAP.

Adjusted Net Income (Loss), Adjusted Net Income (Loss) Per Share—Basic and Diluted

Management of the Company uses adjusted net income (loss) and adjusted net income (loss) per share—basic and diluted to evaluate the Company’s operating performance and for planning and forecasting future business operations. The Company believes the use of these measures allows investors and analysts to compare results of the continuing operations of the Company to similar operating results of other mining companies, by excluding unusual or infrequent items that are considered non-core to our business.

Adjusted net income (loss) represents the income (loss) prepared in accordance with US GAAP, adjusted for significant non-cash items.

For 2015, the significant non-cash items were the net realized and unrealized gains and losses related to the impact of foreign exchange due primarily to intercompany notes, net of related tax effects. Additionally for 2015, in connection with a change in our legal structure we also had a significant non-cash release of tax valuation allowances which were generated in prior years primarily as a result of asset impairments. For 2014 and 2013, the significant non-cash items were the asset impairments, goodwill impairment, and the non-cash net realized and unrealized gain and losses related to the impact of foreign exchange due primarily to intercompany notes, and related tax effects.

In connection with our strategy to manage cash balances, fund our operations and provide future tax benefits, we may enter into intercompany loan arrangements. At times, the loans are denominated in currencies other than the measurement currency of one of the parties. US GAAP requires that notes that are intended to be repaid should not be considered a capital contribution, and, therefore, the foreign exchange fluctuations related to these loans impact net income (loss) each period. At each period end, we compare the exchange rate between the Canadian and US dollars to the exchange rate at the end of the prior reporting period. The difference between those rates is recorded as an unrealized gain or loss on the Consolidated Statements of Operations and Comprehensive Loss at each period end. Settlement of these intercompany loans results in realized foreign exchange gains or losses recorded on the Consolidated Statements of Operations and Comprehensive Loss. The loans between the parent company and its subsidiaries are the primary driver of our foreign exchange gains and losses, as discussed above, management does not consider gains or losses on foreign exchange in its evaluation of our financial performance. We believe that presentation of our non-GAAP measures excluding these gains or losses provides useful information to our investors regarding our financial condition and results of operations.

We review and evaluate our long-lived assets for impairment using a two-step approach when events and changes in circumstances indicate that the related carrying amounts of its assets may not be recoverable. We experienced non-cash impairment write downs of our long-lived assets of different types during 2014 and 2013, as described in Note 5 within Item 8, and, therefore, these charges should not be considered non-recurring. However, management does not consider these impairment charges in its evaluation of our financial performance and excludes non-cash asset write-downs and related tax impacts from adjusted net income (loss) and adjusted net income (loss) per share — basic and diluted. We believe that presentation of our non-GAAP measures excluding these non-cash impairment losses provides useful information to our investors regarding our financial condition and results of operations.

Adjusted net income (loss) per share (basic and diluted) is calculated using adjusted net income (loss), as defined above, divided by the weighted-average basic and weighted-average diluted shares outstanding during the period as determined in accordance with US GAAP. If the adjustments to net (loss) on a US GAAP basis result in non-GAAP adjusted net income, we calculate weighted-average diluted shares outstanding in accordance with US GAAP and use that to calculate adjusted net income per share—diluted. If the adjustments to net income on a US GAAP basis result in non-GAAP adjusted net (loss), we utilize weighted-average basic shares outstanding to calculate adjusted net income per share—diluted, in accordance with US GAAP.

The following tables reconcile net income (loss) presented in accordance with US GAAP to the non-GAAP financial measures of adjusted net income (loss) and adjusted net income (loss) per share—basic and diluted, for the years ended December 31, 2015, 2014 and 2013 and for all of the previous eight quarters. All figures within the tables are unaudited and are presented in US$ in millions, except shares and per share amounts.

⁽¹⁾ The 2014 asset impairments for Endako Mine and TC Mine did not have a net tax impact due to offsetting valuation allowance movement; therefore, the non-GAAP adjusted net income (loss) presentation excluded this tax effect.

⁽²⁾Included $51.6 million in reversal of valuation allowances in connection with a change in our legal structure to utilize certain tax attributes.

⁽³⁾ Included foreign exchange losses of $1.0 million and $1.1 million; a foreign exchange gain of $0.3 million, a foreign exchange loss of $1.6 million, foreign exchange gains of $0.5 million and a $0.6 million foreign exchange loss, presented in income and mining tax expense (benefit) in the Condensed Consolidated Statements of Operations and Comprehensive Loss for the three months ended December 31, 2015, September 30, 2015, June 30, 2015, March 31, 2015, December 31, 2014, and September 30, 2014, respectively.

Copper-Gold Operations - Unit Cash Cost and Average Realized Price per Payable Pound or Payable Ounce Sold

Unit cash cost on a by-product and co-product basis are considered key measures in evaluating operating performance in our Copper-Gold operations, as well as measures of profitability and efficiency on a consolidated basis. Although, unit cash cost on a by-product and co-product basis are not measures of financial performance, do not have standardized meaning prescribed by US GAAP and may not be comparable to similar measures presented by other companies, we use these measures to manage operations and we believe these non-GAAP measures provide useful supplemental information to investors.

Unit cash cost on a by-product and co-product basis represent the mining, milling, on-site general and administration, truck and rail transportation, warehousing, refining and treatment, and ocean freight and insurance costs; and exclude the effects of changes in inventory; non-cash corporate allocations; other non-cash employee benefits, such as stock-based compensation; depreciation, depletion, amortization and accretion.

On a by-product basis, sales of by-product metals are deducted when computing cash costs in accordance with the cash cost standard endorsed by the World Gold Council and, previously, the Gold Institute.

On a co-product basis, cash costs are allocated between copper and gold based on production. Copper production is stated in thousands of pounds. Gold production has been converted to thousands of copper equivalent (Cu eq.) pounds using the gold production for the periods presented, as well as the most recent monthly average prices for copper and gold. The price used for copper is the most recent monthly average of the Metals Bulletin Daily published price for LME settlement per tonne. The price used for gold is a weighted average of the most recent monthly average of the Metals Bulletin Daily published prices for daily average London price per ounce adjusted for the fixed price established under the Gold Stream Arrangement ($435 per oz).

The following tables provide a reconciliation of cash costs, unit cash costs, and operating expenses for Copper-Gold operations included in our Consolidated Statements of Operations and Comprehensive Loss in the determination of net loss.

Critical Accounting Estimates

Management’s Discussion and Analysis of Financial Condition and Results of Operations is based on our consolidated financial statements, which have been prepared in conformity with US GAAP. The preparation of these statements requires that we make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. We base these estimates on historical experience and on assumptions that we consider reasonable under the circumstances; however, there is a reasonable likelihood that materially different amounts could be reported under different conditions or using different assumptions and estimates. The areas requiring the use of management’s estimates are also discussed in Note 2 within Item 8 under the subheading “Use of Estimates.” Management has reviewed the following discussion of its development and selection of critical accounting estimates with the Audit Committee of our Board of Directors.

Asset Impairments

We evaluate the carrying value of long-lived assets to be held and used, using a fair-value based approach when events and circumstances indicate that the related carrying amount of our assets may not be recoverable. The economic environment and copper, gold and molybdenum prices may be considered as impairment indicators for the purposes of these impairment assessments. In accordance with US GAAP, the carrying value of a long-lived asset or asset group is considered impaired when the anticipated undiscounted cash flows from such asset or asset group is less than its carrying value. In that event, an impairment charge will be recorded in our Consolidated Statements of Operations and Comprehensive Loss based on the difference between book value and the estimated fair value of the asset or asset group computed using discounted estimated future cash flows, or the application of an expected fair value technique in the absence of an observable market price. Future cash flows include estimates of recoverable quantities to be produced from estimated proven and probable mineral reserves, commodity prices (considering current and historical prices, price trends and related factors), production quantities and capital expenditures, all based on life-of-mine plans and projections. In estimating future cash flows, assets are grouped at the lowest level for which identifiable cash flows exist that are largely independent of cash flows from other asset groups. Generally, in estimating future cash flows, all assets are grouped at a particular mine for which there are identifiable cash flows. While our 2015 impairment analysis did not result in any long-lived asset impairments, there can be no assurance that there will not be further asset impairments if commodity prices experience a sustained decline and/or if there are significant downward adjustments to estimates of recoverable quantities to be produced from estimated proven and probable mineral reserves or production quantities, upward adjustments to estimated operating costs and capital expenditures and/or changes in C$ to US$ foreign exchange rates, all based on life-of-mine plans and projections.

Table of Contents

Mineral Reserves and Depreciation, Depletion and Amortization

Property, plant, equipment and development are recorded at cost. Expenditures for property, plant, equipment and development relating to new assets or improvements are capitalized if they extend useful lives or extend functionality. Fixed plant and machinery are amortized using the units-of-production method over the estimated life of the ore body based on contained pounds to be produced from estimated proven and probable mineral reserves. Facilities, mobile and other equipment are depreciated on either a declining-balance basis or a straight-line basis over the shorter of their estimated useful life or the life of the mine. Repairs and maintenance costs are charged to expense as incurred, except when these repairs extend the life or functionality of the asset. In these instances, that portion of the expenditure is capitalized and amortized over the period benefited.

The estimate that most significantly affects the units-of-production rate is the quantity of proven and probable molybdenum mineral reserves. The estimation of mineral reserves is complex and involves the use of estimates and assumptions. These estimates and assumptions include the use of geological modeling and sampling, as well as estimates of long-term copper, gold and molybdenum prices and future mining costs. These estimates and assumptions can change as a result of numerous factors, including new information gained from development activities, evolving production history and a reassessment of the viability of production under different economic conditions. Significant judgment is involved in the reserve estimates, and actual results may differ significantly from current assumptions.

Asset Retirement Obligations

Accounting for reclamation and remediation obligations requires management to make estimates of the future costs we will incur to complete the work required to comply with existing laws and regulations at each mining operation. We record the fair value of our estimated asset retirement obligations (AROs) associated with tangible long-lived assets in the period incurred. Fair value is measured as the present value of cash flow estimates after considering inflation and a market risk premium. Our cost estimates are reflected on a third-party cost basis and comply with our legal obligation to retire tangible long-lived assets in the period incurred. Actual costs may differ from the amounts estimated. Also, future changes to environmental laws and regulations could increase the extent of reclamation and remediation work required. Refer to Note 13 within Item 8 for further discussion, including a summary of changes in our AROs for the three years ended December 31, 2015.

Revenue Recognition

For concentrate sales, revenue is recognized when title and risk of loss pass and when collectability is reasonably assured. The passing of title and risk of loss are based on terms of the sales contract, generally upon shipment of product. Revenues from our concentrate sales are recorded based on a provisional sales price, with an adjustment made for a final sales price calculated in accordance with the terms specified in the relevant sales contract. Revenues from concentrate sales are recorded net of treatment and all refining charges and the impact of derivative contracts. Treatment and refining charges represent payments or price adjustments that are contractually negotiated, as typical in the industry. Moreover, because a portion of the metals contained in copper-gold concentrates is unrecoverable as a result of the smelting process, revenues from concentrate sales are also recorded net of allowances based on the quantity and value of these unrecoverable metals.

Under the long-established structure of sales agreements prevalent in the industry, metals contained in concentrate are generally provisionally priced at the time of shipment. The provisional prices are finalized in a specified future month (generally one to four months from the shipment date) based on quoted monthly average spot copper prices on the London Metal Exchange (LME) or the London Bullion Market association (LBMA). We receive market prices based on prices in the specified future month, which results in mark-to-market price fluctuations recorded to revenues until the date of settlement. We have hedging arrangements in place to limit our exposure to such pricing fluctuations.

To satisfy our obligations under the Gold Stream Arrangement, we purchase unallocated refined gold and arrange for delivery to Royal Gold's designated account. We recognize revenue for sales of refined gold when title and risk of loss passes and when collectability is reasonably assured. Revenue from and costs for unallocated refined gold delivered under the Gold Stream Arrangement and gains and losses related to forward commodity gold contracts to manage our Gold Stream Risk are netted and recorded to gold sales.

We recognize revenue from molybdenum sales when persuasive evidence of an arrangement exists, the price is determinable, the product has been delivered, title has transferred and collection is reasonably assured. Our sales contracts specify the point in the delivery process at which title transfers to the customer (shipping point or destination). Shipping and handling fees are accounted for on a gross basis under the terms of the contract. We recognize tolling and calcining revenue under contractual arrangements as the services are performed on a per-unit basis.

Table of Contents

We may enter into provisionally-priced molybdenum purchase contracts, whereby the contracts settle at a discount to the market price for molybdenum oxide. The future pricing mechanism of these agreements constitutes an embedded derivative, which is bifurcated and separately marked to an estimated fair value at the end of each period. Changes to the fair value of embedded derivatives related to molybdenum purchase agreements are included in operating expenses in the Consolidated Statements of Operations and Comprehensive Loss as the product is sold.

Income and Mining Taxes

In preparing the consolidated financial statements, we estimate the actual amount of taxes currently payable or receivable, as well as deferred tax assets and liabilities attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates and laws is recognized in net income (loss) in the period in which such changes are enacted.

A valuation allowance is provided for those deferred tax assets for which it is more likely than not that the related benefits will not be realized. In determining the amount of the valuation allowance, we consider estimated future taxable income, reversal of taxable temporary differences and carry backs in each jurisdiction. Furthermore, we evaluate tax planning strategies, including legal structure changes undertaken to optimize the use of tax attributes, to estimate whether they are prudent and feasible. If we determine that all or a portion of the deferred tax assets will not be realized, a valuation allowance will be increased with a charge to income tax expense. Conversely, if we make a determination that we ultimately will be able to realize all or a portion of the related benefits for which a valuation allowance has been provided, all or a portion of the related valuation allowance will be reduced with a credit to income tax expense.

At December 31, 2015, tax valuation allowances totaled $231.7 million. Of this amount, $89.7 million related to allowances covering some of foreign tax credit, alternative minimum tax credit and tax loss carry-forwards in the US, $50.0 million related to allowances covering some of tax loss carry-forwards in Canada, $44.1 million related to allowances covering realized and unrealized foreign exchange capital losses, and $47.9 million related to allowances covering some of our capital expenditures, primarily at Endako Mine.

The determination of our tax expense and benefit for the year and our future tax assets and liabilities involves significant management estimation and judgment involving a number of assumptions. In determining these amounts, management interprets tax legislation in a variety of jurisdictions and makes estimates and projections of the expected timing of the reversal and realization of future tax assets and liabilities. We also make estimates of future earnings that affect legal structure changes and other tax planning strategy decisions and the extent to which potential future tax benefits may be used. We are subject to assessments by various taxation authorities who may interpret tax legislation differently. These differences may affect the final amount or the timing of the payment of taxes. We provide for such differences where known based on management's best estimate of the probable outcome of these matters.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Commodity Price Risk

Our consolidated revenues include the sale of concentrate from Mount Milligan Mine, from third-party material that is purchased, processed and sold from our and other mines as well as the Langeloth Facility and the sale of molybdenum in various forms from TC and Endako Mines. Our financial results can vary significantly as a result of fluctuations in the market prices of copper, gold and molybdenum.

Copper and Gold

Substantially all of our concentrate sales contracts provide final pricing in a specified future month (generally one to four months from the shipment date) based primarily on quoted LBMA monthly average spot gold prices or quoted LME monthly average spot copper prices. We receive market prices based on prices in the specified future period, which results in price fluctuations recorded through revenues until the date of settlement. To the extent final prices are higher or lower than what was recorded on a provisional basis, an increase or decrease to revenues is recorded each reporting period until the date of final pricing. Accordingly, in times of rising copper and gold prices, our revenues benefit from adjustments to the final pricing of provisionally priced sales pursuant to contracts entered into in prior periods; in times of falling copper and gold prices, the opposite occurs.

Table of Contents

During 2015, we had copper sales totaling 76.5 million pounds of copper recorded at an average realized price of $2.28 per pound, of which approximately 26.1 million pounds are subject to final pricing over the next several months. We estimate that each $0.10 change in the price realized from the December 31, 2015 provisional price recorded would have a net impact on 2015 consolidated revenues of approximately $8.0 million.

During 2015, we had gold sales totaling 221,902 ounces of gold recorded at an average realized price of $950 per ounce, of which approximately 31,719 ounces are subject to final pricing over the next several months. We estimate that each $25 change in the price realized from the December 31, 2015 provisional price recorded would have a net impact on our share of 2015 consolidated revenues of approximately $2.6 million.

To satisfy our obligation under the Gold Stream Arrangement, we purchase unallocated refined gold and arrange for delivery to Royal Gold's designated account. We are currently required to pay Royal Gold upon receipt of final payment from the applicable offtakers. We receive final payments in cash, thus requiring the purchase of gold in order to satisfy the obligation to pay Royal Gold in gold.

In order to hedge our gold price risk that arises when physical purchase and concentrate sales pricing periods do not match, we enter into certain forward gold purchase and sales contracts where we purchase gold at an average price during a quotational period (QP) and sell gold at a spot price. We record our commodity contracts at fair value using a market approach based on observable quoted market prices and contracted prices.

At December 31, 2015, under derivative contracts designed to hedge gold price risk, we had contracts to purchase 31,940 ounces of gold at prices to be determined and we had entered into forward gold sales and gold collars for approximately 23,600 ounces in total with a sell price of $1,130 per ounce, buy price to be determined, a put price range of $1,050 - $1,125 per ounce and a call price range of $1,164 - $1,227 per ounce.

The following table provides details of TCM's open copper and gold forward sales contracts as of February 17, 2016:



	Quantity	Sell Price/Put Price	Buy Price/Call Price	Maturities Through
Forward Gold Sales (oz)	10,000	$1,130 - $1,193	TBD	February 2016 - June 2016
Gold Collars (oz)	26,600	$1,050 - $1,125	$1,164 - $1,278	February 2016 - December 2016

Molybdenum

We enter into certain molybdenum sales contracts to sell future molybdenum production at fixed prices. We have elected to treat these contracts as normal purchase and normal sale contracts. We also enter into certain molybdenum sales contracts to purchase future molybdenum production at provisional prices. To the extent final prices are higher or lower than what was recorded on a provisional basis, an increase or decrease to inventory is recorded each reporting period until the date of final pricing. Accordingly, in times of falling molybdenum prices, molybdenum purchases benefit from lower prices paid for contracts priced at current market rates and also from an decrease related to the final pricing of provisionally-priced purchases pursuant to contracts entered into in prior years; in times of rising molybdenum prices, the opposite occurs. The future pricing mechanism of these agreements constitutes an embedded derivative, which is bifurcated and separately marked to estimated fair value at the end of each period. Changes to the fair values of the embedded derivatives related to provisionally-priced molybdenum purchases are included in operating expenses in the Consolidated Statements of Operations and Comprehensive Loss as the product is sold.

For the year ending December 31, 2015, we estimate that for each $1 per pound change in the price realized for molybdenum purchases, our 2015 net loss would change by approximately $4.0 million.

The following table sets forth our outstanding provisionally-priced molybdenum contracts as of December 31, 2015:



	Pounds to be Sold/Purchased
	(000's lb)
Provisionally-priced contracts:
Purchases	1,836.7
Fixed-price sales contracts:
Molybdenum committed ⁽¹⁾	368.9

⁽¹⁾ As of December 31, 2015 for our fixed-priced molybdenum sales contracts the average price per pound is $7.08. For the years ended December 31, 2015, 2014 and 2013, we treated these contracts as normal purchase and normal sales contracts.

Table of Contents

In the normal course of operations, we enter into agreements for the purchase of molybdenum. As of December 31, 2015, we had commitments to purchase approximately 9.2 million pounds of molybdenum sulfide concentrate from 2016 to 2017, to be priced at a discount to the market price for molybdenum oxide at the time of purchase.

Other

In the normal course of operations, we enter into agreements for the purchase of natural gas for use at the Langeloth facility. As of December 31, 2015, we had commitments to purchase approximately 36.1 thousand dekatherms (dt) from January 2016 - September 2016 at prices ranging from $3.07 - $3.38.

Foreign Currency Exchange Risk

We transact business in various currencies in the normal course of operations. All of our revenues are denominated in the US dollar; however, we pay certain expenses attributable to its Canadian operations in the Canadian dollar. As a result, we have ongoing foreign exchange transaction/translation risk with respect to its Canadian operations. A decrease of 10% in the value of the US dollar relative to the Canadian dollar would have impacted operating income, (excluding the impact of non-cash asset impairments), during the year ended December 31, 2015 by approximately $27.9 million.

To help mitigate this risk, from time to time, we enter into foreign currency forward contracts, in which we have agreed to buy Canadian dollars at an agreed-upon rate. Please refer to Note 6 within Item 8 of this 10-K for further discussion. We record our currency contracts at fair value using a market approach based on observable quoted exchange rates and contracted notional amounts. As of December 31, 2015, we had 26 open foreign currency contracts. The following table provides details of our open forward currency contracts as of February 17, 2016:

1. Description of Business

Thompson Creek Metals Company Inc. ("TCM") is a North American mining company incorporated under the laws of British Columbia with copper, gold and molybdenum mining, milling, processing and marketing operations in Canada and the United States ("US").

The Copper-Gold operations consist of Mount Milligan Mine, a conventional truck-shovel open-pit copper and gold mine and concentrator in British Columbia. The US operations for molybdenum include the Thompson Creek Mine ("TC Mine") (mine and mill) in Idaho and the Langeloth Metallurgical Roasting Facility (the "Langeloth Facility") in Pennsylvania. The Canadian operations for molybdenum consist of a 75% joint venture interest in the Endako Molybdenum Mine Joint Venture ("Endako Mine") (mine, mill and roaster) in British Columbia. Due to continued weakness in the molybdenum market Endako Mine was placed on temporary suspension in December 2014 and subsequently was placed on care and maintenance effective July 1, 2015. As previously disclosed in TCM's 2014 Form 10-K, TC Mine was placed on care and maintenance in December 2014 after the processing of stockpiled ore from Phase 7 was completed. During 2015, TC Mine conducted limited stripping for the next phase of mining (referred to as “Phase 8”). As part of TCM's cost reduction measures, further stripping at TC Mine ceased effective August 6, 2015. As of January 2016, TCM is operating a commercial molybdenum beneficiation circuit at TC Mine to treat molybdenum concentrates to supplement the concentrate feed TCM sources directly for the Langeloth facility.

The costs related to the Endako Mine temporary suspension and care and maintenance and TC Mine care and maintenance are reflected in costs for idle mining operations in the Consolidated Statements of Operations and Comprehensive Loss. The test-work costs related to the molybdenum beneficiation circuit are reflected in operating expenses in the Consolidated Statements of Operations and Comprehensive Loss.

TCM also has a 100% interest in a copper and molybdenum exploration property located in British Columbia (the “Berg property”) and a 0.51% net smelter return royalty and a 10.2% net profits interest in a zinc and lead exploration project located in Canada (the "Howards Pass property").

2. Significant Accounting Policies

Basis of Preparation and Principles of Consolidation

The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States ("US GAAP"). The consolidated financial statements include the accounts of TCM and its subsidiaries, and intercompany accounts and transactions have been eliminated in consolidation. TCM also consolidates its 75% proportionate interest in the accounts of the unincorporated Endako Mine joint venture.

Certain prior year amounts in the financial statements have been reclassified to conform to the current year presentation. Intercompany accounts and transactions have been eliminated in consolidation. Financial amounts are presented in United States (“US”) dollars unless otherwise stated. References to C$ are Canadian dollars.

New Accounting Standards

In November 2015, the Financial Accounting Standards Board ("FASB") issued an Accounting Standards Update ("ASU") in connection with the balance sheet classification of deferred taxes. The objective of this ASU is to simplify the presentation of deferred income taxes. The amendments in this ASU require that deferred tax liabilities and assets be classified as non-current in a classified statement of financial position. This ASU is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Earlier application is permitted for all entities as of the beginning of an interim or annual reporting period. TCM adopted this ASU effective October 1, 2015. Upon adoption, TCM adjusted its December 31, 2014, balance sheet by decreasing its current and non-current deferred tax assets by $0.1 million and $11.5 million, respectively and decreasing current deferred tax liabilities by $14.1 million and increasing non-current deferred tax liabilities by $2.5 million.

2. Significant Accounting Policies (Continued)

In July 2015, the FASB issued an ASU that simplified the subsequent measurement of inventory by requiring entities to measure inventory at the lower of cost or net realizable value, except for inventory measured using the last-in, first-out (LIFO) or the retail inventory methods. Under the new guidance, entities are only required to compare the cost of inventory to one measure - net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. For public entities, this ASU is effective for annual periods beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted as of the beginning of an interim or annual reporting period. This ASU must be applied prospectively. TCM adopted this ASU effective October 1, 2015, and it had no impact on its results of operations.

In April and August 2015, the FASB issued ASUs to simplify the presentation of debt issuance costs. These ASUs require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. For public entities, these ASUs are effective for annual periods beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued. TCM will adopt this ASU effective January 1, 2016.

Use of Estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities as of the date of the financial statements and the reported amounts of revenues and expenditures during the reporting period. As the estimation process is inherently uncertain, actual future outcomes could differ from current estimates and assumptions, potentially having material effects on future financial statements. The more significant areas requiring the use of management estimates include mineral reserve estimation; useful asset lives for depreciation, depletion and amortization; reclamation and closure costs; environmental obligations; deferred taxes and valuation allowances; asset fair values in evaluating asset impairments and estimates of recoverable copper, gold and other minerals.

Currency Translation

The functional currency of TCM and its US operations is the US dollar. Monetary assets and liabilities denominated in foreign currencies are translated into US dollars at exchange rates in effect at the balance sheet date, with resulting gains or losses reported in loss (gain) on foreign exchange in the computation of net (loss) income. Other non-monetary assets and liabilities are translated at historic rates. Revenues, expenses and cash flows in foreign currencies are translated into US dollars at average exchange rates.

The functional currency of TCM's Canadian operations is the Canadian dollar. The assets and liabilities for those subsidiaries with a Canadian dollar functional currency are translated at exchange rates in effect at the balance sheet date, and revenues and expenditures are translated at average exchange rates. Differences arising from these foreign currency translations are recorded in the Consolidated Balance Sheets as accumulated other comprehensive income (loss) within Shareholders' equity.

Fair Value Measurement

US GAAP accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The standards establish a fair value hierarchy that distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) an entity's own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below:

(US dollars in millions, except per share amounts)

2. Significant Accounting Policies (Continued)



Level 1		Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
Level 2		Quoted prices in markets that are not active or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability.
Level 3		Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity).

Cash and Cash Equivalents and Restricted Cash

Cash comprises cash deposits held at banks. Cash equivalents are financial instruments issued or guaranteed by major financial institutions and governments that have an original maturity date of less than 90 days. Cash equivalents are stated at cost, which approximates market value. Restricted cash is primarily amounts withheld related to certain construction contracts and amounts to fund TCM's deferred compensation program.

Accounts Receivable

Accounts receivable are carried at their estimated collectible amounts. As of December 31, 2015, accounts receivable included trade accounts receivables of $52.8 million, Goods and Services Sales Tax refunds receivable of $1.4 million, third party molybdenum receivables of $0.2 million and other miscellaneous receivables of $0.2 million, partially offset by $1.9 million of mark-to-market adjustments relating to provisional invoices for copper and gold concentrate sales.

As of December 31, 2014, accounts receivable included trade accounts receivables of $45.1 million, Goods and Services Sales Tax refunds receivable of $2.0 million, Langeloth Facility receivables of $0.9 million, third party molybdenum receivables of $0.3 million and settlement receivables on hedges and other miscellaneous receivables of $1.3 million, partially offset by $3.5 million of mark-to-market adjustments relating to provisional invoices for copper and gold concentrate sales.

Product Inventories

Product inventories are carried at the lower of cost or net realizable value, as of October 1, 2015. Prior to that date product inventories were carried at the lower of cost or market and assessed monthly to determine if a write down was required. Cost comprises production costs for copper-gold concentrate ("concentrate") and molybdenum concentrate ("molybdenum") produced and processed from TCM's mines, as well as amounts paid for molybdenum concentrate purchased from third parties. Production costs include the direct mining, milling and on-site general and administrative costs; costs of processing, beneficiation and roasting; transportation, shipping, freight and insurance costs; refining and treatment costs; warehouse costs; stock-based compensation and depreciation, depletion and amortization. Stripping costs (i.e., the costs of removing overburden and waste material to access mineral deposits) incurred during the production phase of a mine are considered variable production costs and are included as a component of inventory produced during the period in which stripping costs are incurred. For concentrate, TCM uses the weighted-average cost method for production and sales of product inventory. For molybdenum, TCM uses the first-in, first-out cost method for production and sales of product inventory. For both the copper-gold and molybdenum operations, the weighted-average cost method is used for stockpiled ore.

Obsolescence

TCM routinely evaluates materials and supplies inventory for obsolescence. When necessary, obsolete and surplus materials and supplies are written down in a manner that reduces the inventory value to an amount that does not exceed its net realizable value, which may be considered salvage value, with the difference charged to current period expenses. During 2015, 2014 and 2013, TCM recorded write downs for obsolete materials and supplies inventory of $0.2 million, $2.8 million and $2.4 million, respectively.

2. Significant Accounting Policies (Continued)

Property, Plant, Equipment and Development

Mineral Properties

TCM capitalizes the costs to acquire mineral properties. On acquisition of a mineral property, TCM estimates the fair value of proven and probable mineral reserves, as well as the value beyond proven and probable mineral reserves, and records any costs incurred as assets at the date of acquisition. The costs assigned to mineral properties in production are amortized over the life of the mine using the units-of-production method based on the volume of mineral produced in relation to the total estimated proven and probable mineral reserves. The cost assigned to the value beyond proven and probable mineral reserves is not amortized. However, as new information is obtained or economic conditions change, mineralized material may be converted into proven and probable mineral reserves at which time the capitalized costs associated with mineralized material are reclassified as costs subject to amortization.

Mine Development

Capitalization of mine development costs that meet the definition of an asset begins once all operating permits have been secured, mineralization is classified as proven and probable reserves and a final feasibility study has been completed. Mine development costs include engineering and metallurgical studies, drilling and other related costs to delineate an ore body and the removal of overburden to initially expose an ore body at open pit surface mines. Costs incurred before mineral resources are classified as proven and probable reserves are expensed and classified as exploration expense, unless it can be substantiated prior to the commencement of a drilling program that the drilling costs will result in the conversion of a mineral resource into proven and probable reserves. All capitalized costs are amortized using the units-of-production method over the estimated life of the ore body based on recoverable quantities to be produced from estimated proven and probable mineral reserves. Interest expense allocable to the cost of developing mining properties and to construct new facilities is capitalized until assets are ready for their intended use. Gains or losses from sales or retirements of assets are included in costs and expenses on the Consolidated Statements of Operations and Comprehensive Loss. Tax credits, which will be used to offset future taxable income, generated from qualifying new mine development costs are included as reductions to property, plant, equipment and development and increases to deferred tax assets on the Consolidated Balance Sheets. The benefit from these tax incentives will be reflected in net income (loss) over the estimated life of the ore body, along with the capitalized mine development costs which generated the credits.

Facilities and Equipment

Mining facilities and equipment are recorded at cost. Expenditures for facilities and equipment relating to new assets or improvements are capitalized if they extend useful lives or extend functionality. Fixed plant and machinery are amortized using the units-of-production method over the lesser of the estimated life of the equipment or the ore body based on recoverable quantities to be produced from estimated proven and probable mineral reserves. Facilities, mobile and other equipment are depreciated on either a declining-balance or straight-line basis over the shorter of their estimated useful life or the life of the mine. The declining-balance percentages range from 10% to 50%, and the estimated useful lives range from 3 years to life-of-mine. Processing facilities are depreciated on a straight-line basis over the estimated useful lives ranging from 2 to 20 years. Tax allowances, which will be used to offset future taxable income, generated from qualifying new mine facilities and equipment expenditures are included as reductions to property, plant, equipment and development and increases to deferred tax assets on the Consolidated Balance Sheets. The benefit from these tax incentives will be reflected in net income over estimated life of the facilities and equipment, along with the associated expenditures which generated the allowances.

Repairs and maintenance costs are charged to expense as incurred, except when these repairs extend the life or functionality of the asset. In these instances, expenditures are capitalized and amortized over the period benefited.

Depreciation, depletion and amortization is allocated to product inventory cost and then included in depreciation, depletion and amortization as inventory is sold.

Additionally, interest expense and financing fees allocable to the cost of developing mining properties and to constructing new facilities is capitalized until assets are ready for their intended use. See Note 9 for further discussion.

2. Significant Accounting Policies (Continued)

Exploration

Exploration includes geological and geophysical work on areas without identified reserves, together with drilling and other related costs. These costs are expensed as incurred.

Asset Impairments

TCM reviews and evaluates its long-lived assets for impairment using a two-step approach when events and changes in circumstances indicate that the related carrying amounts of its assets may not be recoverable. If total estimated future cash flows on an undiscounted basis are less than the carrying amount of the assets (step 1), TCM performs an evaluation of the estimated fair value of the asset or asset group (step 2). An impairment loss is measured and recorded based on the difference between book value and the estimated fair value of the asset or asset group. Fair value is estimated using discounted estimated future cash flows, or the application of an expected fair value technique in the absence of an observable market price. Future cash flows include estimates of recoverable quantities to be produced from estimated proven and probable mineral reserves, commodity prices (considering current and historical prices, price trends and related factors), production quantities and capital expenditures, all based on life-of-mine plans and projections. In estimating future cash flows, assets are grouped at the lowest level for which identifiable cash flows exist that are largely independent of cash flows from other asset groups. Generally, in estimating future cash flows, all assets are grouped at a particular mine for which there are identifiable cash flows. The assumptions underlying future cash flow estimates are subject to significant risks and uncertainties. Any differences between TCM's assumptions and market conditions and/or TCM's operating performance could have a material effect on the determination of ore reserves or the ability to recover the carrying amounts of TCM's long-lived assets, thus resulting in impairment charges.

See Note 5 for further discussion of TCM's 2014 and 2013 impairment charges.

Legal Fees

TCM generally recognizes legal expenses as incurred. When it is determined that a contingency meets the criteria for recognition as a liability on the balance sheet, TCM also accrues for the related incurred legal fees associated with that probable contingency.

Debt Issuance Costs

Included in other long-term assets are costs associated with the issuance of TCM's Senior Notes (2017 Notes, 2018 Notes and 2019 Notes as defined in Note 9) and tangible equity units ("tMEDS"). The remaining unamortized issuance costs at December 31, 2015 totaled $9.9 million and are being amortized over the life of the Senior Notes. The unamortized costs at December 31, 2014 totaled $15.3 million, and were amortized over the life of the Senior Notes or the tMEDS, as applicable. Amortization costs for the Senior Notes and tMEDS were capitalized to Mount Milligan Mine until the underlying assets became ready for their intended use.

Equipment Financings

TCM is the lessee of equipment under the Equipment Facility with Caterpillar (see Note 8). In 2013, TCM entered into an equipment financing transaction with Caterpillar with respect to certain Endako Mine equipment. In 2013, TCM also entered into equipment financing transactions with Caterpillar with respect to certain equipment at Mount Milligan Mine pursuant to the Equipment Facility. TCM's ability to finance additional equipment under the Equipment Facility expired in September 2015 per the amended terms of the Equipment Facility agreement. The assets and liabilities under these capital leases are recorded at the lower of the present value of the minimum lease payments or the fair value of the asset. Once ready for their intended use, the assets are depreciated over the lower of their related lease terms or their estimated productive lives. Beginning in September 2013, in conjunction with the start-up phase of Mount Milligan Mine, TCM ceased capitalizing the interest and debt issuance costs associated with the leases under the Equipment Facility for Mt. Milligan Mine as the related assets were placed in service.

2. Significant Accounting Policies (Continued)

Financial Instruments

From time to time, TCM enters into various arrangements, such as forward commodity contracts, foreign currency forward contracts and fixed- and provisionally-priced purchase and sale contracts. TCM does not account for any of these arrangements using hedge accounting.

Financial and derivative instruments (including embedded derivatives) are recorded at fair value on the Consolidated Balance Sheets. Changes in the fair value of derivatives are recorded each period in the Consolidated Statements of Operations and Comprehensive Loss.

Provision for Income and Mining Taxes

TCM computes income taxes using the asset and liability approach that results in the recognition of deferred tax assets and liabilities for the expected future tax consequences or benefits of temporary differences between the financial reporting basis and the tax basis of assets and liabilities, as well as operating loss and tax credit carry-forwards, using enacted tax rates in effect in the years in which the differences are expected to reverse.

In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of its deferred tax assets will not be realized. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, carryback of losses and tax planning strategies in making this assessment. A valuation allowance is provided for the portion of TCM's net deferred tax assets for which it is not more likely than not that they will be realized.

Asset Retirement Obligations

Future obligations to retire an asset, including site closure, dismantling, remediation and ongoing treatment and monitoring, are recorded as a liability at fair value at the time of construction or development. The fair value determination is based on estimated future cash flows, the current credit-adjusted risk-free discount rate and an estimated inflation factor. The value of asset retirement obligations is evaluated on an annual basis or as new information becomes available on the expected amounts and timing of cash flows required to discharge the liability. The fair value of the liability is added to the carrying amount of the associated asset, and this additional carrying amount is depreciated or amortized over the estimated life of the asset. An accretion cost, representing the increase over time in the present value of the liability, is recorded each period as accretion expense. As reclamation work is performed or liabilities are otherwise settled, the recorded amount of the liability is reduced.

Revenue Recognition

TCM sells its products pursuant to sales contracts entered into with its customers. For concentrate sales, revenue is recognized when title and risk of loss pass and when collectability is reasonably assured. The passing of title and risk of loss are based on terms of the sales contract, upon shipment. Revenues from TCM’s concentrate sales are recorded based on a provisional sales price, with adjustments made for a final sales price calculated in accordance with the terms specified in the relevant sales contract, including the price to be received under the Gold Stream Arrangement, as well as any potential losses from TCM's commitment under the Gold Stream Arrangement. Revenues from concentrate sales are recorded net of treatment and all refining charges and the impact of derivative contracts. Treatment and refining charges represent payments or price adjustments that are contractually negotiated, as is typical in the industry. Moreover, because a portion of the metals contained in concentrate is unrecoverable as a result of the smelting process, TCM's revenues from concentrate sales are also recorded net of allowances based on the quantity and value of these unrecoverable metals.

2. Significant Accounting Policies (Continued)

Under the long-established structure of sales agreements prevalent in the industry, metals contained in concentrate are generally provisionally priced at the time of shipment. The provisional prices are finalized in a specified future month (generally one to four months from the shipment date) based on quoted monthly average spot gold prices on the London Metal Exchange ("LME") or spot copper prices on the London Bullion Market Association ("LBMA"). TCM receives market prices based on prices in the specified future month, which results in mark-to-market price fluctuations recorded to revenues until the date of settlement. To the extent final prices are higher or lower than what was recorded on a provisional basis, an increase or decrease to revenues is recorded each reporting period until the date of final pricing. For changes in metal quantities upon receipt of new information and assay, the provisional sales quantities are adjusted as well.

To satisfy its obligations under the Gold Stream Arrangement, TCM purchases unallocated refined gold and arranges for delivery to Royal Gold, Inc's ('Royal Gold") designated account. TCM recognizes revenue for sales of refined gold when title and risk of loss passes and when collectability is reasonably assured. Revenue from and costs for unallocated refined gold delivered under the Gold Stream Arrangement and gains and losses related to TCM's forward commodity gold contracts to hedge the Company's exposure under the Gold Stream Arrangement are netted and recorded to gold sales.

TCM recognizes revenue from molybdenum sales when persuasive evidence of an arrangement exists, the price is fixed and determinable, the product has been delivered, title has transferred and collection is reasonably assured. TCM's sales contracts specify the point in the delivery process at which title transfers to the customer (shipping point or destination). Shipping and handling fees are accounted for on a gross basis under the terms of the contract. TCM recognizes tolling and calcining revenue under contractual arrangements as the services are performed on a per-unit basis.

TCM enters into provisionally-priced molybdenum, copper and gold sales contracts, whereby the contracts settle at prices to be determined at a future date based upon quoted prices. The future pricing mechanism of these agreements constitutes an embedded derivative, which is bifurcated and separately marked to an estimated fair value at the end of each period. Changes to the fair value of embedded derivatives related to molybdenum purchase agreements are included in operating expenses in the Consolidated Statements of Operations and Comprehensive Loss as the product is sold.

Stock-Based Compensation

Stock Options

TCM measures compensation related to stock options based on the fair value of instruments issued. The fair value of stock options at grant date is estimated using a Black-Scholes option pricing model. Compensation expense is recognized on a straight-line basis over the stock option vesting period and included in the specific income statement categories that include the costs and benefits of the employees granted the stock-based award. Proceeds arising from the exercise of stock options are credited to common stock.

Performance Share Units

Performance share units ("PSUs") are accounted for at fair value using a Monte Carlo simulation valuation model on the date of grant. The Monte Carlo model is based on random projections of stock price paths. Expected volatility is calculated using a weighted average of historical daily volatilities and represents the extent to which TCM's stock price performance is expected to fluctuate during each of the calendar periods of the award's anticipated term. The fair value is recognized as an expense on a straight-line basis over the requisite service period (usually the vesting period) and included in the specific income statement categories that include the costs and benefits of the employees granted PSUs. Upon vesting, common shares are issued to the employee from authorized but unissued common stock. According to the provisions of ASC 718, Compensation—Stock Compensation, stock based compensation expense is reversed for unvested and forfeited PSUs.

2. Significant Accounting Policies (Continued)

Restricted Stock Units

Restricted stock units ("RSUs") are accounted for at fair value, which is based on the market value of TCM's common shares on the day of grant. The total fair value is recognized as an expense on a straight-line basis over the vesting period and included in the specific income statement categories that include the costs and benefits of the employee and directors granted RSUs. Upon vesting, common shares are issued to the employee or director from authorized but unissued common stock. According to the provisions of ASC 718, Compensation—Stock Compensation, stock based compensation expense is reversed for unvested and forfeited RSUs.

Employee Stock Purchase Plan

TCM's employee stock purchase plan ("ESPP") provides an opportunity for TCM's employees to purchase its common shares at 85% of the closing price at the beginning of the offering period or at the end of the offering period, whichever is lower. Effective May 13, 2014, TCM shareholders approved the Amended and Restated Thompson Creek Metals Company Inc. 2010 Employee Stock Purchase Plan that makes additional shares of TCM's common stock available for issuance. The ESPP was suspended effective January 1, 2016.

Earnings per Share

Earnings per share calculations are based on the weighted-average number of common shares issued and outstanding during the year. Diluted earnings per share are calculated using the treasury stock method, which assumes that outstanding stock options and warrants with an average exercise price less than the average market price of TCM's common shares are exercised, and the proceeds are used to repurchase common shares at the average market price of the common shares for the period. In years in which a loss is incurred, the effect of potential issuances of shares under the exercise of options, warrants and RSUs would be anti-dilutive, and therefore, are excluded from diluted earnings per share calculations.

3. Inventory

The carrying value of product inventory was as follows:



	December 31, 2015		December 31, 2014
Copper and Gold Inventory:
Concentrate	$	19.4	$	29.4
Stockpiled ore	15.6		8.3
	$	35.0	$	37.7
Molybdenum Inventory:
Finished product	$	12.3	$	45.0
Work-in-process	8.5		13.5
Stockpiled ore	—		0.4
	$	20.8	$	58.9
	$	55.8	$	96.6

During 2015, 2014 and 2013, the carrying value of TCM's product inventory exceeded its market or net realizable value, resulting in write downs.

The following table sets forth the write downs of TCM's product inventory in the accompanying Consolidated Statements of Operations and Comprehensive Loss for the years ended December 31, 2015, 2014 and 2013:

⁽²⁾The construction-in-progress balances consisted primarily of projects at Mount Milligan Mine. As of December 31, 2015, the construction-in-progress consisted of $15.2 million primarily related to the permanent secondary crusher at Mount Milligan Mine, $0.6 million related to the beneficiation circuit at TC Mine and $0.6 million in ongoing operating capital at Langeloth. The construction-in-progress balance at December 31, 2014 consisted primarily of costs for Phase 2 of the tailings facility system at the Mount Milligan Mine.

During the years ended December 31, 2015, December 31, 2014 and December 31, 2013 TCM recognized non-cash property plant equipment and development asset impairments of nil, $92.0 million and $188.0 million, respectively. See Note 5 for further discussion of asset impairments.

5. Asset Impairments

Our impairment analysis did not result in any long-lived asset impairments during 2015. TC Mine and Endako Mine molybdenum assets were impaired to their overall liquidation values in 2014 as discussed below.

The following table sets forth the write downs of property, plant, and equipment and development assets, mineral reserves, materials and supplies inventory and goodwill in the accompanying Consolidated Statements of Operations and Comprehensive Loss for the years presented:

5. Asset Impairments (Continued)

Effective December 31, 2014, TCM and its joint venture partner temporarily suspended operations at Endako Mine due to significant declines in commodity prices and ongoing weakness in the molybdenum price. Additionally, given mining performance for 2014, there was a decrease in the Endako Mine molybdenum proven and probable reserves. The temporary suspension and reserve decrease constituted triggering events, requiring TCM to re-evaluate its proportionate share of Endako Mine's long-lived assets for impairment in the fourth quarter of 2014. This evaluation indicated that TCM's share of the anticipated undiscounted cash flows from Endako Mine assets, using the two-step approach discussed in Note 2, were less than its share of the carrying value of the fixed assets due to the expected future molybdenum price and anticipated production and cash costs from the Endako Mine. This resulted in estimating TCM's share of the assets’ estimated fair value, which was also less than TCM's share of their carrying values. As a result of this evaluation during 2014 TCM recorded non-cash write downs of the Endako Mine property, plant and equipment assets and materials and supply inventory.

Additionally, as of December 31, 2014, TCM evaluated the fair value of its exploration properties given the significant decline in commodity prices in the fourth quarter of 2014. This evaluation indicated that the fair value of these properties was less than TCM's carrying values and non-cash write downs were recognized in the fourth quarter of 2014, representing a write-down to the assets’ estimated fair value as of December 31, 2014. Given the weakness in commodity markets, as of December 31, 2014, TCM also evaluated the fair value of its remaining materials and supplies inventory at TC Mine; the fair value of TC Mine’s materials and supplies inventory was less than the carrying value resulting in non-cash write downs in 2014.

As of December 31, 2013, TCM's decision to place TC Mine on care and maintenance and the update to its Endako Mine molybdenum reserves using a price of $10 per pound of molybdenum oxide compared to $12 per pound used previously, constituted triggering events, requiring TCM to evaluate the long-lived assets at these mines for impairment in the fourth quarter of 2013. As a result of these analyses, TCM recorded a non-cash asset impairment, representing a write down to the assets' estimated fair value as of December 31, 2013. Additionally during 2013, TCM negotiated a contract with US Energy to sell land originally acquired by one of its subsidiaries for easements related to the Mt. Emmons project, in respect of which TCM terminated its interest in 2011. TCM assessed the impact of this contract on the carrying value of the land, and recorded a non-cash write down of the land representing a write down to the land's fair value.

These impairment charges were included in total costs and expenses in TCM's Consolidated Statements of Operations and Comprehensive Loss.

6. Financial Instruments

TCM enters into various derivative financial instruments in the normal course of operations to manage exposure to the market prices of copper, gold and molybdenum. TCM does not apply hedge accounting to its derivative instruments. Accordingly, changes in fair value of derivative instruments are recorded in the Consolidated Statements of Operations and Comprehensive Loss, except those contracts for which TCM has elected to apply the normal purchases and normal sales scope exception.

The following table provides details about the fair values of TCM's derivative assets and liabilities:



	Fair Value as of December 31,

6. Financial Instruments (Continued)

TCM's commodity and currency derivative assets are included in prepaid expenses and other current assets, and similar types of derivative liabilities are included in other current liabilities. Provisionally-priced sales assets or liabilities are included in accounts receivable. TCM is exposed to credit risk when counterparties with which it has entered into derivative transactions are unable to satisfy their obligations. To reduce counterparty credit exposure, TCM deals primarily with large, credit-worthy financial institutions and companies and limits credit exposure to each. TCM believes the counterparties to the contracts to be credit-worthy entities and, therefore, TCM believes credit risk of counterparty non-performance is relatively low, and as such, the fair value of the derivatives has not been adjusted.

The following table sets forth the (losses) gains on derivative instruments for the years presented:

Gold Hedges Related to Gold Stream Arrangement and Other Commodity Contracts

TCM must satisfy its obligation under the Gold Stream Arrangement (discussed in Note 10) by delivering gold to Royal Gold after TCM receives payment from third-party purchasers, including offtakers and traders, that purchase concentrate from Mount Milligan Mine ("MTM Customers"). During 2015,TCM delivered gold to Royal Gold based on a percentage of the gold ounces included in each final sale of gold to MTM Customers within two days of receiving a final payment. If the final payment from an MTM Customer is not received within five months of the provisional payment date, then TCM will deliver an estimated amount of gold ounces based on information that is available from the MTM Customer at that time.

TCM receives payment from MTM Customers in cash, thus requiring the purchase of gold in order to satisfy the obligation to pay Royal Gold in gold. In order to hedge its gold price risk that arises when physical purchase and concentrate sales pricing periods do not match, hereafter referred to as the Gold Stream Risk, TCM has entered into certain forward gold purchase and sales contracts pursuant to which it purchases gold at an average price during a quotational period and sells gold at a spot price. TCM records its forward commodity contracts at fair value using a market approach based on observable quoted market prices and contracted prices.

In addition to the Gold Stream Risk and in connection with the sale of concentrate from Mount Milligan Mine, TCM is exposed to copper and gold price fluctuations between the dates of concentrate shipment, provisional payment and final payment. In order to hedge the price risk for the metals contained in concentrate, TCM has entered into certain forward copper and gold purchase and sale contracts pursuant to which it purchases copper or gold at an average price during a quotational period and sells copper or gold at a spot price. Additionally, TCM has entered into zero cost collars pursuant to which it agrees with a counterparty to a floor and ceiling relative to future prices of gold. If the gold price is below the floor, the counterparty pays TCM the difference between the price and the floor. If the gold price is above the ceiling, TCM pays the counterparty the difference between the ceiling and the price. TCM records its commodity contracts at fair value using a market approach based on observable quoted market prices and contracted prices. These financial instruments are intended to protect TCM against the price risk related to the MTM Customer purchase contracts.

The following table provides details of TCM's commodity contracts as of December 31, 2015:

Provisionally-Priced Contracts

Certain copper-gold and molybdenum sales contracts provide for provisional pricing. These sales contain an embedded derivative related to the provisional-pricing mechanism, which is bifurcated and accounted for as a derivative. TCM also enters into provisionally-priced molybdenum purchase contracts that also contain an embedded derivative, which is bifurcated and accounted for as a derivative.

TCM determines the fair value of its provisionally-priced contracts using a market approach based upon observable inputs from published market prices and contract terms. Changes to the fair values of the embedded derivatives related to provisionally-priced molybdenum purchases are included in operating expenses in the Consolidated Statements of Operations and Comprehensive Loss as the product is sold.

The following table sets forth TCM's outstanding provisionally-priced contracts as of December 31, 2015:



		Average Price Per Unit
	Open Positions	Contract	Market	Maturities Through
Embedded derivatives in provisional sales contracts:
Copper (millions of pounds)	26.1	TBD	TBD	March 2016
Gold (ounces)	31,719	TBD	TBD	March 2016
Embedded derivatives in provisional purchase contracts:
Molybdenum (millions of pounds)	1.8	N/A	TBD	February 2016

Forward Currency Contracts

TCM transacts business in various currencies in the normal course of its operations and for capital expenditures. In addition, with all of its revenues denominated in US dollars, TCM has an ongoing foreign exchange risk with respect to its Canadian operations. To help mitigate this risk, TCM has entered into foreign currency forward contracts pursuant to which it has agreed to buy Canadian dollars at an agreed-upon rate. TCM records its currency contracts at fair value using a market approach based on observable quoted exchange rates and contracted notional amounts. As of December 31, 2015 and December 31, 2014, TCM had 26 and 8 open foreign currency option contracts, respectively.

The following table provides details of TCM's forward currency contracts as of December 31, 2015:

Fixed-Priced Contracts

TCM has entered into certain sales contracts pursuant to which it sells future molybdenum production at fixed prices. These fixed prices may be different than the quoted market prices at the date of sale. TCM has elected to treat these contracts as normal purchase and normal sale contracts.

7. Fair Value Measurement

US GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The standards establish a fair value hierarchy that distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) an entity's own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The sensitivity to changes in inputs and their impact on the fair value measurement can be significant. The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below:



Level 1		Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
Level 2		Quoted prices in markets that are not active or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability.
Level 3		Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity).

As of December 31, 2015 and 2014, TCM held certain items that were required to be measured at fair value on a recurring basis. These included derivative assets and liabilities which consist of commodity and foreign currency derivative instruments and provisionally priced contracts. In addition to the fair value disclosure requirements related to financial instruments carried at fair value, TCM has provided disclosures regarding the fair value of all of TCM's financial instruments in accordance with US GAAP. The methods and significant assumptions used to estimate the fair value of these financial instruments and any changes in methods or significant assumptions from prior periods have also been disclosed. As required, financial instruments are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

The following tables set forth TCM's financial liabilities measured at fair value by level within the fair value hierarchy.



	Fair Value at December 31, 2015

7. Fair Value Measurement (Continued)

TCM classified its currency contracts within Level 1 because they are valued using a market approach based on observable quoted exchange rates and contracted notional amounts. TCM classified its senior secured and unsecured notes within Level 2 because they are valued using discounted cash flow valuation models which use a mix of inputs including a risk-free interest rate input that is quoted in an active market and credit spreads. The risk-free interest rate and credit spread inputs are negatively correlated to the fair value measure; an increase (decrease) in the input will decrease (increase) the fair value measure. TCM classified its commodity contracts and provisionally priced contracts within Level 2 because they are valued using a market based approach, other than observable quoted prices included within Level 1, other inputs from published market prices and contracted prices and terms. TCM classified its tMEDS within Level 3 because they are valued using significant unobservable inputs. TCM determined the fair value of the debt component of tMEDS using a discounted cash flow model by obtaining yields for comparably-rated issuers trading in the market, considering the market yield of existing TCM debt and the credit rating of TCM.

As of December 31, 2015, the carrying values of the 9.75% senior secured notes, the 7.375% senior unsecured notes and the 12.5% senior unsecured notes were higher than their fair values of $257.6 million, $61.1 million and $35.6 million, respectively.

As of December 31, 2015, the carrying values of TCM's financial instruments approximated their fair values. TCM determined the fair value of its financial instruments using LME or COMEX copper and gold forward prices and option pricing models using the counterparties' and TCM's credit quality. See Note 6 for more information regarding TCM's financial instruments.

On May 15, 2015, the prepaid share purchase contract portion of each outstanding tangible equity units ("tMEDS") was automatically settled at the maximum settlement rate of 5.3879 shares of common stock. TCM issued a total of 6,105,210 shares of common stock in connection with such settlement. See Note 12 for more information regarding the tMEDS.

As of December 31, 2014, the carrying values of the 9.75% senior secured notes were lower than their fair values of approximately $393.2 million, while the carrying value of the 7.375% senior unsecured notes, the 12.5% senior unsecured notes and tMEDS were higher than their fair values of $273.0 million, $180.3 million and $0.4 million, respectively.

There were no transfers into or out of Level 3 during the years ended December 31, 2015 and 2014. TCM's policy is to recognize transfers as of the actual date of the event or change in circumstances.

The following table sets forth a reconciliation of activity related to Level 3 financial liabilities for the years ended December 31, 2015 and 2014:



	Debt

Settlement and revaluation of tMEDS	—
Balance at December 31, 2014	$	0.4
Settlement of tMEDS	(0.4		)
Balance at December 31, 2015	$	—

In addition to assets and liabilities that are recorded at fair value on a recurring basis, TCM records certain assets and liabilities at fair value on a nonrecurring basis. Generally, assets are recorded at fair value on a nonrecurring basis as a result of impairment charges when required by US GAAP. See Note 5 for further discussion of asset impairments.

Equipment Financings

TCM entered into an equipment financing facility, as amended from time to time (the "Equipment Facility"), pursuant to which Caterpillar Financial Services Limited ("Caterpillar") agreed to underwrite up to $132.0 million in mobile fleet equipment financing for Mount Milligan Mine. Each borrowing under the Equipment Facility represents a capital lease and has a term of 48 or 60 months. Interest on the amounts borrowed under the Equipment Facility is payable at either floating or fixed rates, at TCM's option. At the end of each 48 or 60 month lease period, TCM has the option to purchase the underlying equipment for a nominal sum. The Equipment Facility includes non-financial covenants, and as of December 31, 2015, TCM was in compliance with these covenants. TCM's ability to finance additional equipment under the Equipment Facility expired in September 2015 per the amended terms of the Equipment Facility agreement. During 2015, TCM entered into two new capital leases pursuant to the Equipment Facility. The leases resulted in an increase of $8.3 million to TCM's capital lease obligation after total upfront payments of $0.9 million. Interest payments are based on an annual fixed rate of 5.70%. TCM did not enter into any new capital leases pursuant to the Equipment Facility in 2014.

During 2013, TCM entered into three leases with Caterpillar with respect to certain equipment pursuant to the Equipment Facility, of which two are considered sale-leaseback transactions. Interest payments are based on a fixed rate of 5.50%

As of December 31, 2015 and 2014, TCM had $51.3 million and $66.2 million, respectively, in outstanding borrowings under the Equipment Facility. Interest pertaining to the Equipment Facility is allocable to the cost of developing mining properties and to constructing new facilities and is capitalized until assets are ready for their intended use. Beginning in September 2013, in conjunction with the start-up phase of Mount Milligan Mine, TCM ceased capitalizing the interest and debt issuance costs associated with the leases under the Equipment Facility for Mount Milligan Mine as the related assets were placed in service.

Separate from the Equipment Facility, during 2013, TCM entered into a sale-leaseback transaction with Caterpillar with respect to 75% of certain Endako Mine equipment. TCM received $5.3 million in cash from Caterpillar for the sale of this equipment, which was subsequently leased back, after an upfront down payment of $1.4 million. Interest payments are based on a fixed rate of 5.85%. On September 4, 2015, TCM assumed the lease for the remaining 25% of the equipment and subsequently transferred this equipment to Mount Milligan Mine. In connection with this transfer, TCM paid $0.3 million to Sojitz, TCM's Endako Mine joint venture partner, for its 25% share of the fair value of the leased equipment and recognized an additional sale-leaseback obligation of $0.5 million. The agreement includes certain non-financial covenants, and as of December 31, 2015, TCM was in compliance with these covenants.

Interest and debt issuance costs on the equipment financings, as described above, consisted of the following:

9.75% Senior Secured Notes

On November 27, 2012, TCM issued $350.0 million of 9.75% senior secured notes (the “2017 Notes”). The proceeds received in the offering were $336.8 million, net of financing fees of $10.0 million and a discount of $3.2 million. The net proceeds from the 2017 Notes offering were used to fund the completion of Mount Milligan Mine and for general working capital purposes. The 2017 Notes are guaranteed on a senior basis by substantially all of TCM's subsidiaries and are secured by a first priority lien subjected to permitted liens on substantially all of TCM's and the guarantors' property and assets.

The 2017 Notes mature on December 1, 2017 and accrue interest from November 27, 2012 until maturity at a fixed rate of 9.75% per year. Interest on the 2017 Notes is payable on February 1 and August 1 of each year, commencing February 1, 2013, to the holders of record at the close of business on the January 15 and July 15 prior to each interest payment date.

The 2017 Notes are governed by a base indenture, dated May 11, 2012, supplemented by the first supplemental indenture, dated May 11, 2012, and the fifth supplemental indenture, dated November 27, 2012 (the “2017 Notes Indenture”). There are no maintenance covenants with respect to TCM's financial performance. However, the 2017 Notes Indenture does contain transaction-based restrictive covenants that restrict TCM's ability and the ability of certain of TCM's subsidiaries to incur additional indebtedness; pay dividends or make other distributions or repurchase or redeem capital stock; prepay, redeem or repurchase certain debt; make loans and investments; sell assets; incur liens; enter into transactions with affiliates; and enter into agreements restricting the Company's subsidiaries ability to pay dividends and consolidate, merge or sell all or substantially all of TCM's assets, in each case subject to certain exceptions.

The 2017 Notes are redeemable at TCM's option at any time prior to December 1, 2015 at a price equal to 100% of the principal amount of the 2017 Notes, plus accrued and unpaid interest and a make-whole premium. TCM may also redeem up to 35% of the original principal amount of the 2017 Notes at any time prior to December 1, 2015 with the proceeds of certain equity offerings at a redemption price of 109.75% of the principal amount of the 2017 Notes, together with accrued and unpaid interest to, but not including, the date of redemption. TCM may also redeem the 2017 Notes at any time on or after December 1, 2015 at the redemption prices specified in the 2017 Notes Indenture together with accrued and unpaid interest to, but not including, the date of redemption. Finally, TCM may redeem the 2017 Notes at any time upon the occurrence of specified events relating to Canadian tax law at a redemption price of 100% of the principal amount of the 2017 Notes plus accrued and unpaid interest to, but not including, the date of redemption.

The 2017 Notes Indenture contains customary events of default. If an event of default occurs and is continuing under the 2017 Notes Indenture, the trustee or holders of at least 25% in principal of the outstanding 2017 Notes may declare the principal, premium, if any, and accrued and unpaid interest on all the 2017 Notes to be due and payable immediately. Certain events of bankruptcy or insolvency are events of default that would result in the 2017 Notes being due and payable immediately upon the occurrence of such events of default.

During 2015, TCM repurchased $34.2 million of its 2017 Notes in a privately negotiated transaction and recorded a debt extinguishment loss of $3.1 million and reduced $0.5 million and $0.8 million of the related unamortized debt issuance costs and discount amortization, respectively.

7.375% Senior Unsecured Notes

On May 20, 2011, TCM issued $350.0 million of 7.375% senior unsecured notes (the "2018 Notes"). The proceeds received in the offering were $339.9 million, net of financing fees of $10.1 million. The net proceeds from the 2018 Notes offering were used to fund the development of Mount Milligan and for general working capital purposes. The 2018 Notes are guaranteed on a senior basis by substantially all of the Company's subsidiaries.

The 2018 Notes mature on June 1, 2018 and accrue interest from May 20, 2011 until maturity at a fixed rate of 7.375% per year. Interest is payable on June 1 and December 1 of each year, and the first interest payment occurred on December 1, 2011. Interest is payable to the holders of record at the close of business on the May 15 and November 15 prior to each interest payment date.

The 2018 Notes are governed by an indenture, dated May 20, 2011 (the “2018 Notes Indenture”). There are no maintenance covenants with respect to TCM's financial performance. However, the 2018 Notes Indenture does contain transaction-based restrictive covenants that restrict the Company's ability and the ability of certain of TCM subsidiaries to incur additional indebtedness; pay dividends or make other distributions or repurchase or redeem capital stock; prepay, redeem or repurchase certain debt; make loans and investments; sell assets; incur liens; enter into transactions with affiliates; enter into agreements restricting the Company's subsidiaries ability to pay dividends and consolidate, merge or sell all or substantially all of TCM assets, in each case subject to certain exceptions.

TCM may redeem the 2018 Notes at any time upon the occurrence of specified events relating to Canadian tax law at a redemption price of 100% of the principal amount of the 2018 Notes plus accrued and unpaid interest to, but not including, the date of redemption.

The 2018 Notes Indenture contains customary events of default. If an event of default occurs and is continuing under the 2018 Notes Indenture, the trustee or holders of at least 25% in principal of the outstanding 2018 Notes may declare the principal, premium, if any, and accrued and unpaid interest on all the 2018 Notes to be due and payable immediately. Certain events of bankruptcy or insolvency are events of default that would result in the 2018 Notes being due and payable immediately upon the occurrence of such events of default. In December 2011, TCM completed an exchange offer of the original 2018 Notes for a like principal amount of exchange notes registered under the Securities Act of 1933, pursuant to a registration rights agreement with the initial purchasers.

During 2015 and 2014, TCM repurchased $1.7 million and $14.2 million, respectively of its 2018 Notes in open market transactions and recorded a debt extinguishment gain of $0.3 million and $2.3 million, respectively and reduced the related unamortized debt issuance costs by an insignificant amount and $0.3 million, respectively.

12.5% Senior Unsecured Notes

On May 11, 2012, TCM issued $200.0 million of 12.5% senior unsecured notes (the “2019 Notes”). The proceeds received in the offering were $193.1 million, net of financing fees of $6.9 million. The net proceeds from the 2019 Notes offering were used to fund the completion of Mount Milligan Mine and for general working capital purposes. The 2019 Notes are guaranteed on a senior basis by substantially all of TCM's subsidiaries.

The 2019 Notes mature on May 1, 2019 and accrue interest from May 11, 2012 until maturity at a fixed rate of 12.5% per year. Interest on the 2019 Notes is payable on May 1 and November 1 of each year, commencing November 1, 2012, to the holders of record at the close of business on the April 15 and October 15 prior to each interest payment date.

The 2019 Notes are governed by a base indenture as supplemented by the first and second supplemental indentures thereto, each dated May 11, 2012 (the “2019 Notes Indenture”). There are no maintenance covenants with respect to the Company's financial performance. However, the 2019 Notes Indenture does contain transaction-based restrictive covenants that restrict the Company's ability and the ability of certain of the Company's subsidiaries to incur additional indebtedness; pay dividends or make other distributions or repurchase or redeem capital stock; prepay, redeem or repurchase certain debt; make loans and investments; sell assets; incur liens; enter into transactions with affiliates; and enter into agreements restricting the Company's subsidiaries ability to pay dividends and consolidate, merge or sell all or substantially all of TCM assets, in each case subject to certain exceptions.

The 2019 Notes are redeemable at TCM's option at any time prior to May 1, 2016 at a price equal to 100% of the principal amount of the 2019 Notes, plus accrued and unpaid interest and a make-whole premium. TCM may also redeem up to 35% of the original principal amount of the 2019 Notes at any time prior to May 1, 2015 with the proceeds of certain equity offerings at a redemption price of 112.5% of the principal amount of the 2019 Notes, together with accrued and unpaid interest to, but not including, the date of redemption. TCM may also redeem the 2019 Notes at any time on or after May 1, 2016 at the redemption prices specified in the 2019 Notes Indenture together with accrued and unpaid interest to, but not including, the date of redemption. Finally, TCM may redeem the 2019 Notes at any time upon the occurrence of specified events relating to Canadian tax law at a redemption price of 100% of the principal amount of the 2019 Notes plus accrued and unpaid interest to, but not including, the date of redemption.

The 2019 Notes Indenture contains customary events of default. If an event of default occurs and is continuing under the 2019 Notes Indenture, the trustee or holders of at least 25% in principal of the outstanding 2019 Notes may declare the principal, premium, if any, and accrued and unpaid interest on all the 2019 Notes to be due and payable immediately. Certain events of bankruptcy or insolvency are events of default that would result in the 2019 Notes being due and payable immediately upon the occurrence of such events of default.

During 2015, TCM repurchased $5.5 million of the 2019 Notes in open market transactions and recorded an insignificant debt extinguishment loss and reduced $0.1 million of the related unamortized debt issuance costs.

Mobile Mining Equipment Loans

On December 8, 2010, TCM executed an equipment financing agreement with Caterpillar in the amount of $12.8 million secured by six units of mobile mining equipment purchased by TCM during 2010. As of December 31, 2015, all obligations with respect to the mobile mining equipment loans had been satisfied.

10. Gold Stream Arrangement

Pursuant to the Gold Stream Arrangement, TCM agreed to sell to Royal Gold 52.25% of the refined gold production from Mount Milligan Mine for a total upfront payment of $781.5 million, plus $435 per ounce, or the prevailing market rate if lower than $435 per ounce, when the gold is delivered. The upfront cash payments of $781.5 million (referred to herein as the "Record of Deposit") which were received under the Gold Stream Arrangement were recorded as deferred revenue and classified as a liability on TCM's Consolidated Balance Sheets.

10. Gold Stream Arrangement (Continued)

The Gold Stream Arrangement restricts TCM's ability to incur debt that is secured by the Mount Milligan Mine assets. Subject to the exceptions discussed below, TCM cannot incur debt that is secured by the Mount Milligan Mine assets in excess of $350.0 million until the earlier of the date upon which 425,000 ounces of refined gold have been sold and delivered to Royal Gold or the date upon which the aggregate dollar amount of the difference between the market price for the gold delivered to Royal Gold and the price actually paid by Royal Gold exceeds $280.0 million. Per a December 2014 amendment, TCM is additionally permitted to pledge the Mount Milligan Mine assets to secure up to $25.0 million of hedging obligations incurred in connection with gold and copper production from Mount Milligan Mine, foreign currency exchange risk relating to Mount Milligan Mine and one or more corporate credit facilities utilized in connection with Mount Milligan Mine. Provided that Mount Milligan Mine meets specified throughput, recovery and delivery conditions, the $25.0 million would increase to $50.0 million. As of December 31, 2015, these conditions have been met and Royal Gold concurred with the achievement of those conditions in January 2016.

TCM must maintain the Record of Deposit during the term of the Gold Stream Arrangement wherein TCM reduces the $781.5 million total amount paid by Royal Gold by the difference between the current market price at the time of sale of refined gold to Royal Gold and $435 per ounce, multiplied by the amount of refined gold sold in such sale. If, at the end of the initial 50-year term of the Gold Stream Arrangement, the total deposit amount reflected in the deposit record has not been reduced to nil, TCM must pay to Royal Gold the remaining balance reflected in the deposit record. As of December 31, 2015, the remaining deposit per the Gold Stream Arrangement totaled $653.5 million. In the event of any default by TCM under the Gold Stream Arrangement, Royal Gold could require TCM to repay the outstanding deposit. The remaining Record of Deposit differs from the unrecognized deferred revenue for accounting purposes.

Royal Gold has a security interest in all of the Mount Milligan Mine assets until its total deposit amount has been reduced to nil. Royal Gold's security interest is subject to subordination to project or corporate financings by TCM, except that in such circumstances, Royal Gold retains a first priority interest in 52.25% of the refined gold from Mount Milligan Mine. After the total deposit amount has been reduced to nil, Royal Gold's security will consist solely of its first priority interest in 52.25% of the refined gold. The cash payments received under the Gold Stream Arrangement are recorded as deferred revenue and classified as a liability on TCM's Consolidated Balance Sheets.

TCM sells copper and gold concentrate from Mount Milligan Mine to MTM Customers, and then purchases gold ounces in the market for delivery to Royal Gold, in an amount based on a portion of the gold ounces in the copper and gold concentrate sold to MTM Customers as determined in accordance with the terms of the Gold Stream Arrangement. Mount Milligan Mine began selling copper and gold concentrate to MTM Customers and delivering gold ounces to Royal Gold in the fourth quarter of 2013, at which time TCM began to recognize an amount of the deferred revenue as gold ounces are delivered to Royal Gold, as explained further below. In connection with TCM's first 12 shipments of copper and gold concentrate (which concluded in the fourth quarter of 2014) from Mount Milligan Mine to MTM Customers, TCM was required to deliver gold ounces to Royal Gold based on a percentage of gold ounces in each provisional sale of gold to MTM Customers within two days of receiving a provisional payment for the sale of the copper and gold concentrate, with subsequent delivery of the remaining gold ounces upon final settlement. Thereafter, all deliveries of gold to Royal Gold were based solely on the final settlement of provisional sales of concentrate to MTM Customers and payable at the time of final settlement. The gold ounces delivered to Royal Gold under the Gold Stream Arrangement are based on the contained gold ounces in the provisional payments and final settlements multiplied by a 97% payable factor.

Revenues from the Gold Stream Arrangement are recognized upon the provisional sale of the copper and gold concentrate delivered to MTM Customers based on the amount of the provisional gold ounces in such sale, with adjustments made for the $435 per ounce price, the per ounce price for the deferred revenue that was received upfront pursuant to the terms of the Gold Stream Arrangement and certain adjustments.

The components of revenue under the Gold Stream Arrangement are as follows:


•	recognition of an amount of deferred revenue based on the amount of gold ounces delivered to Royal Gold in the applicable period compared to total expected gold deliveries over the life of the mine;


•	recognition of receipts of $435 per ounce, or the prevailing market rate if lower than $435 per ounce, when the gold ounces are delivered;


•	recognition of any unrealized losses resulting from the difference between the $435 per ounce plus the deferred revenue per ounce price and the prevailing spot price at the end of any period, net of purchase costs for the gold ounces delivered to Royal Gold; and


•	gains or losses related to TCM's commodity gold contracts used to hedge TCM’s Gold Stream Risk, as defined above.

12. Tangible Equity Units ("tMEDS")

As of December 31, 2015, all obligations with respect to the tMEDS had been satisfied and no tMEDS remain outstanding. On May 11, 2012, TCM completed a public offering of 8,800,000 tMEDS with a stated value of $25.00. Each tMEDS unit consisted of a prepaid common stock purchase contract and a senior amortizing note due May 15, 2015. In June 2014, TCM completed an exchange offer whereby 7,206,862 units, or 86.4% of the then outstanding tMEDS, were tendered for exchange and accepted by TCM. In exchange for the tendered tMEDS, TCM issued 42,129,829 shares of its common stock.

On May 15, 2015, the prepaid share purchase contract portion of each outstanding tMED unit was automatically settled at the maximum settlement rate of 5.3879 shares of common stock. TCM issued a total of 6,105,210 shares of common stock in connection with such settlement. TCM also made the final installment payment on the amortizing note portion of each outstanding tMED unit, satisfying in full the principal and interest payments on the tMEDS. The mandatory settlement and final installment payment were made pursuant to the terms of the prospectus dated May 8, 2012, under which the tMEDS were offered in May 2012.

For the years ended December 31, 2015, 2014 and 2013, TCM paid $0.1 million, $1.3 million and $3.1 million, respectively, and expensed $0.1 million, $1.2 million and $0.6 million, respectively, of the interest and debt issuance costs associated with the tMEDS. For the years ended December 31, 2014 and 2013, TCM capitalized $0.1 million and $2.7 million, respectively, of the interest and debt issuance costs associated with the tMEDS.

13. Asset Retirement Obligations

Asset Retirement Obligations arise from the acquisition, development, construction and normal operation of mining property, plant, equipment and development due to government controls and regulations that protect the environment on the closure and reclamation of mining properties. The exact nature of environmental issues and costs, if any, which TCM may encounter in the future are subject to change, primarily because of the changing character of environmental requirements that may be enacted by governmental agencies.

The following table details items affecting asset retirement obligations for future mine closure and reclamation costs in connection with TCM's Mount Milligan Mine, TC Mine, Endako Mine (reflecting 75% ownership) and its now-terminated interest in the Davidson property for the three years ended December 31, 2015:



	Mt. Milligan			Thompson Creek Mine			Endako Mine			Davidson Property			Total
At January 1, 2013	$	4.3		$	21.5		$	10.5		$	0.3		$	36.6

At December 31, 2015	$	2.8		$	14.3		$	16.6		$	0.1		$	33.8

⁽¹⁾ At December 31, 2014 the downward revision to the asset retirement obligation at TC Mine resulted in a $6.2 million decrease to depreciation, depletion and amortization in the Consolidated Statements of Operations and Comprehensive Loss.

TCM is required by US federal and state laws and Canadian provincial laws to provide financial assurance sufficient to allow a third party to implement approved closure and reclamation plans if TCM is unable to do so. These laws are complex and vary from jurisdiction to jurisdiction. The laws govern the determination of the scope, cost of the closure, reclamation obligation and the amount and forms of financial assurance. As of December 31, 2015 and 2014, TCM has provided the appropriate regulatory authorities in the US and Canada with $72.5 million and $78.6 million, respectively, in non-cash reclamation financial assurance for mine closure obligations which are secured by $10.0 million and $10.3 million in cash deposits as of December 31, 2015 and 2014, respectively.

The current reclamation bonding for TC Mine is $42.3 million as of December 31, 2015. TCM has provided surety bonds which are secured by $10.0 million in cash deposits, to satisfy these obligations. The estimated future reclamation costs for TC Mine have been discounted using rates from 6.7% to 20.4%. As of December 31, 2015, TCM anticipates that these costs will be incurred from 2031 to 2045. The total inflated and undiscounted estimated reclamation costs for TC Mine were $42.1 million and $44.6 million as of December 31, 2015 and 2014, respectively.

In connection with the development of Mount Milligan Mine, the Province of British Columbia required us to provide a reclamation deposit in the amount of $21.7 million and $25.9 million as of December 31, 2015 and 2014, respectively. The estimated future reclamation costs for Mount Milligan Mine have been discounted using rates from 11.0% to 20.4%. As of December 31, 2015, TCM anticipates that these costs will be incurred beginning in the year 2037. The total inflated and undiscounted estimated reclamation costs for Mount Milligan Mine were $36.1 million and $43.1 million as of December 31, 2015 and 2014, respectively.

13. Asset Retirement Obligations (Continued)

For Endako Mine, the British Columbia Ministry of Energy, Mines and Petroleum Resources required TCM to provide a reclamation deposit in the amount of $11.1 million and $13.2 million as of December 31, 2015 and 2014, respectively. TCM's proportionate share was $8.3 million and $9.9 million as of December 31, 2015 and 2014, respectively. TCM's share of total inflated and undiscounted estimated reclamation costs for Endako Mine were $29.2 million and $35.6 million as of December 31, 2015 and 2014, respectively. As of December 31, 2015, TCM estimates its proportionate share of these costs will be incurred from 2015 to 2031. The estimated future reclamation costs for Endako Mine have been discounted using rates from 2.94% to 20.40%.

TCM's Berg property was acquired in the 2010 acquisition of Terrane. The Province of British Columbia required TCM to provide a reclamation deposit in the amount of $0.1 million as of December 31, 2015 for the Berg property.

During 2015, TCM's reclamation deposits related to Mount Milligan Mine, Endako Mine and the Berg property were in the form of letters of credit secured by a guarantee. Under the arrangements, the ACE Group, a surety company, provided a guarantee to Export Development Canada ("EDC"), who provided a guarantee to Royal Bank of Canada ("RBC"), who issued letters of credit to the British Columbia Ministry of Energy and Mines. TCM pays total annual fees of approximately 1.7% of the total reclamation bond guarantee to the surety company, EDC and RBC.

In October 2013, TCM relinquished the option to develop the Davidson exploration property located in British Columbia, Canada that TCM had held since 2005. As of December 31, 2015, TCM has $0.1 million remaining in reclamation bonds that are held by the British Columbia Ministry of Energy and Mines in connection with pending water quality monitoring obligations. TCM believes that all reclamation obligations have been met that arose during TCM's option period.

14. Employee Benefits

Retention and Severance

As of December 31, 2015 and 2014, TCM's total retention and severance liability was $0.6 million and $1.5 million, respectively. For the years ended December 31, 2015, 2014 and 2013, TCM recognized an expense of $7.4 million, $7.2 million and $6.0 million, respectively, for retention and severance arrangements.

Defined Contribution Pension Plans

TCM, through its subsidiaries, maintains defined contribution pension plans available to certain employees. TCM's Thompson Creek Metals Company Thrift Plan (the "Plan") is a defined contribution pension plan and covers all eligible employees employed in the US. The Plan is subject to the provisions of the US Employee Retirement Income Security Act of 1974, as amended, and Section 401(k) of the US Internal Revenue Code. The assets of the Plan are held and the related investment transactions are executed by the Plan's trustee. Administrative fees, including accounting and attorney fees, are paid by TCM on behalf of the Plan. TCM contributed approximately $1.1 million, $1.7 million and $1.8 million, respectively, to the Plan for the years ended December 31, 2015, 2014 and 2013. TCM may make additional contributions to the Plan at its sole discretion; however, TCM has no further obligation relating to benefits under this Plan.

TCM has formed the Thompson Creek Metals Company Inc. Registered Pension Plan (the "Pension Plan") covering all Canadian employees. The assets of the Pension Plan are held and the related investment transactions are executed by the Pension Plan's trustee. Administrative fees, including any accounting and legal fees, are paid by TCM on behalf of the Pension Plan. All participating locations of the Pension Plan contributed C$1.8 million, C$2.7 million and C$2.4 million to the Pension Plan for the years ended December 31, 2015, 2014 and 2013, respectively. TCM has recorded its proportionate 75.0% share related to Endako Mine contributions. TCM has no further obligation relating to pension benefits under this Pension Plan.

Post Retirement Benefits

Under the union agreement at the Langeloth Facility, TCM is required to provide post retirement medical benefits for certain retired former employees and their dependents by making the monthly medical insurance premium payments on their behalf. Substantially all of Langeloth's current unionized employees may become eligible for this benefit if certain age and service requirements are met at the time of retirement, as specified in the union agreement. The benefit ceases when the eligible retired employee reaches 65 years of age. TCM does not have any obligation related to eligible retired unionized employees

beyond the monthly medical insurance premiums. Prior service costs, actuarial gains and losses and transition obligations are amortized over the average life expectancy of the plan's participants.

The following table sets forth the actuarial present value of post retirement medical benefit obligations and amounts recognized in TCM's consolidated financial statements:



	December 31, 2015			December 31, 2014
Change in benefit obligations:
Net benefit obligation at beginning of year	$	4.0		$	3.2
(Gain) loss	(1.0		)	0.6
Service cost	0.4			0.3
Interest cost	0.1			0.1
Benefits paid	(0.1		)	(0.2		)
	$	3.4		$	4.0

The liability of $3.4 million and $4.0 million was included in other liabilities on TCM's Consolidated Balance Sheets as of December 31, 2015 and 2014, respectively.

The assumptions used to determine the benefit obligations as of December 31, 2015 included a measurement date of December 31, 2015 and a discount rate of 4.2%. The yield curve matching TCM's benefit obligation was derived using a cash flow analysis under the Citigroup pension liability index. The Citigroup pension discount curve shows the relationship between interest rates and the duration for hypothetical zero coupon investments. This yield curve was used in determining the discount rate for TCM's post retirement benefit obligation.

The components of net periodic benefit costs for the year ended December 31, 2015 included $0.4 million of service cost and $0.1 million of interest cost for a total net periodic benefit cost of $0.5 million.

The health care cost trend assumed that average cost of coverage was 7.0% for 2015, reduced by 0.25% annually through 2021 and from there being reduced by 0.5% to an ultimate trend of 4.5% in 2024 and beyond. The assumed health care cost trend rates can have a significant effect on the amounts reported for post retirement medical benefits. The effect of a one percent change in the health care cost trend rate used to calculate periodic post retirement medical costs and the related benefit obligation would be insignificant to this benefit obligation.

The expected post retirement medical benefits provided below were based on actuarial assumptions.

14. Employee Benefits (Continued)

Employee Stock Purchase Plan

The ESPP was suspended effective January 1, 2016. The ESPP, which was initially approved by TCM's shareholders in May 2010, provided an opportunity for TCM's employees to purchase its common shares at 85% of the closing price at the beginning of the offering period or at the end of the offering period, whichever is lower. Effective May 13, 2014, TCM's shareholders approved the Amended and Restated Thompson Creek Metals Company Inc. 2010 Employee Stock Purchase Plan (as amended and restated, the "ESPP"), which (i) makes an additional 2,000,000 shares of the Company's common stock available for issuance; (ii) changes the frequency of offering periods to four consecutive three-month offering periods per year; (iii) allows the Compensation Committee to establish sub-plans or special rules designed to achieve desired tax or other objectives for employees outside of the U.S.; (iv) allows the Compensation Committee to exclude from any sub-plan the limit on an employee's right to accrue common stock pursuant to the ESPP at a rate that exceeds $25,000 in market value of common stock per calendar year; (v) allows the Compensation Committee to change the frequency and/or duration of offering periods with respect to future offerings; (vi) caps the number of shares that any employee may purchase in any offering period and in any calendar year at 5,000 and 20,000 shares, respectively; (vii) allows for participation in the ESPP by any employee employed as of an enrollment date; and (viii) permits participants in the ESPP to change their contribution rates during offering periods, subject to limitations imposed by the Compensation Committee.

As of December 31, 2015 there are 1,136,885 shares authorized for purchase by TCM's employees under the ESPP. Compensation expense is measured based on the fair value using a Black-Scholes model of the employees' option to purchase shares of common stock at the grant date. Compensation expense is recognized over the future periods in which the related employee service is rendered. TCM estimated a fair value of employee options to purchase shares under the ESPP of $0.75 for the first two three-month offering periods of 2014. TCM recorded $0.1 million, $0.2 million and $0.2 million of expense related to the ESPP plan for the years ended December 31, 2015, 2014 and 2013, respectively. For the year ended December 31, 2015, TCM issued 917,232 shares of common stock under the ESPP. No tax benefit is realized for ESPPs unless there is a disqualifying disposition. As discussed above, the ESPP was suspended effective January 1, 2016.

15. Shareholders' Equity

The authorized share capital of TCM comprised an unlimited number of common shares and an unlimited number of preferred shares, issuable in series with terms determinable upon issuance. As of December 31, 2015, TCM has not issued any preferred shares.

During 2015, 2014 and 2013, TCM issued 6,105,210, 42,129,828 and 2,109,330 in shares of common stock, respectively, in settlement of certain prepaid common stock purchase contracts for a total of 50,344,368 common shares. These prepaid common stock purchase contracts were issued as part of the 2012 issuance of tMEDS. As of December 31, 2015, all obligations with respect to the tMEDS had been satisfied and no tMEDS remain outstanding. See Note 12 for further discussion.

16. Stock-Based Compensation

On May 13, 2014, TCM's shareholders approved the Amended and Restated 2010 Long-Term Incentive Plan (the "LTIP"). The LTIP allows TCM to grant stock options, share appreciation rights, restricted shares, RSUs, PSUs or shares granted as bonus compensation. As of December 31, 2015, the number of common shares authorized for awards under the LTIP plan is 7.5 million. Effective November 21, 2013, Mr. Perron, TCM's Chief Executive Officer, was granted a one-time inducement award comprising stock options to purchase 400,000 shares of TCM's common stock and 300,000 RSUs, each vesting in three equal annual installments beginning on the first anniversary of the date of grant. The stock options will be exercisable for five years from the date of grant. These grants were made as an employment inducement award outside of the LTIP.

TCM does not realize a tax benefit for stock-based awards granted to Canadian employees under the current Canadian tax law. As of December 31, 2015, TCM has granted stock options, PSUs and RSUs, as discussed below.

TCM recognized stock-based compensation expense as follows:



	Years Ended December 31,
	2015		2014		2013
Stock options	$	0.3	$	0.4	$	0.6
Performance share units	2.6		$	2.7	2.3
Restricted stock units	2.8		$	2.4	2.5
Total stock-based compensation expense	5.7		5.5		5.4

Stock-based compensation expense is included within general and administrative expense, cost of goods sold and exploration expense within the Consolidated Statements of Operations and Comprehensive Loss.

16. Stock-Based Compensation (Continued)

The expiration date and vesting provisions of stock options granted are established at the time an award is made. Stock options vest over 3 years and are exercisable over a period of time not to exceed 10 years from the grant date but generally expire 5 years from the grant date. When an option is exercised, TCM issues the requisite shares from authorized but unissued common stock. The exercise price of options granted prior to March 1, 2011 is equal to the greater of: (i) the volume weighted-average trading price of the underlying shares on the Toronto Stock Exchange over the five consecutive trading days immediately before the grant date and (ii) if the award date occurs in a trading black-out period, the weighted-average trading price over the five consecutive trading days immediately after the black-out period has been lifted. The exercise price of options granted after March 1, 2011 is equal to the volume weighted-average trading price of the underlying shares over the five consecutive trading days immediately before the grant date.

The following table summarizes stock option activity for the three years ended December 31, 2015:

16. Stock-Based Compensation (Continued)

As of December 31, 2015, approximately 0.4 million outstanding options had not vested and were not exercisable. The total unrecognized compensation cost related to these options was $0.3 million as of December 31, 2015 and is expected to be recognized over a weighted-average period of 1.8 years.

The weighted-average fair value of stock options on the date of grant, and the assumptions used to estimate the fair value of the stock options using a Black-Scholes option valuation model were as follows:

Performance Share Units

The vesting of the PSUs granted subsequent to January 1, 2012 and prior to January 1, 2014 is contingent upon two performance metrics: 1) TCM's Total Shareholder Return (TSR) relative to the Russell 2000 Index during the three-year performance period and 2) the proven and probable mine reserves replaced by TCM during the three-year performance period as measured by the replacement reserves percentage determined by the plan administrator. The PSUs cliff vest three years from the date of issuance upon achievement of the above metrics. Any PSUs not vested at such time will expire.

The vesting of the PSUs granted subsequent to January 1, 2014 is contingent upon two performance metrics: 1) TCM's Total Shareholder Return (TSR) relative to the S&P TSX Global Base Metals Index during the three-year performance period and 2) cash flow from operations, defined as TCM's aggregate "cash generated by (used in) operating activities" less aggregate "capital expenditures" as reported for the calendar years 2014, 2015 and 2016 in the Statements of Cash Flows in the Company's Annual Report on Form 10-K. The PSUs cliff vest approximately three years from the date of issuance, or on the date in the first quarter of 2017 that the plan administrator determines and certifies the achievement of the above metrics. Any PSUs not vested at such time will expire.

All PSUs granted are accounted for at fair value using a Monte Carlo simulation valuation model on the date of grant. The Monte Carlo model is based on random projections of stock price paths. Expected volatility is calculated using a weighted average of historical daily volatilities and implied volatility and represents the extent to which TCM's stock price performance is expected to fluctuate during each of the three calendar-year periods of the award's anticipated term.

At December 31, 2015, unrecognized compensation expense related to PSUs totaled $5.2 million that will be recognized on a straight-line basis over a weighted-average period of 1.8 years.

Restricted Stock Units

TCM accounts for RSUs at fair value, which is based on the market value of TCM's common shares on the day of grant and recognized over the vesting period of 3 years. Upon vesting, TCM will issue the requisite shares from authorized but unissued common stock. At December 31, 2015, unrecognized compensation expense related to restricted stock units totaled $2.7 million that will be recognized on a straight-line basis over a weighted-average period of 1.7 years.

17. Commitments and Contingencies

Legal Matters

TCM is from time to time involved in or subject to legal proceedings related to its business. While it is not feasible to predict or determine the outcome of these proceedings, it is the opinion of management that the resolution of such proceedings is not expected to have a material adverse effect on TCM's consolidated financial position, results of operations or cash flows.

Concentrate Sales Agreements

As of December 31, 2015, TCM is party to four multi-year concentrate sales agreements for the sale of concentrate produced at Mount Milligan Mine. Pursuant to these agreements, TCM has agreed to sell an aggregate of the copper and gold concentrate produced at Mount Milligan Mine of approximately 120,000 tonnes in 2016, 60,000 tonnes in 2017 and 40,000 tonnes in 2018. Pricing under these concentrate sales agreements will be determined by reference to specified published reference prices during the applicable quotation periods. Payment for the concentrate will be based on the price for the agreed copper and gold content of the parcels delivered, less smelting and refining charges and certain other deductions, if applicable. The copper smelting and refining charges will be negotiated in good faith and agreed by the parties for each contract year based on terms generally acknowledged as industry benchmark terms. The gold refining charges are as specified in the agreements. Remaining concentrate produced at Mount Milligan Mine will be sold under short-term contracts or on a spot basis.

Molybdenum Purchases

In the normal course of operations, TCM enters into agreements for the purchase of molybdenum. As of December 31, 2015, TCM had commitments to purchase approximately 9.2 million pounds of molybdenum as unroasted molybdenum concentrate from 2016 to 2017 primarily priced at the time of purchase at a set discount to the market price for roasted molybdenum concentrate.

Molybdenum Sales

In the normal course of operations, TCM enters into certain molybdenum sales contracts pursuant to which it sells future production at fixed prices. As of December 31, 2015, TCM had commitments to sell approximately 369 thousand pounds of molybdenum oxide in 2016 at an average price of $7.08 per pound.

Capital Purchase Commitments

As of December 31, 2015, TCM had open capital purchase commitments of $25.8 million related to the Mount Milligan Mine which are expected to be incurred during 2016.

Net Deferred Tax Assets (Liabilities)

Deferred tax assets and liabilities arise from temporary differences in the recognition of income and expenses for financial reporting and tax purposes. As previously discussed, effective October 1, 2015, TCM adopted an ASU in connection with the balance sheet classification of deferred taxes. Upon adoption, TCM adjusted its December 31, 2014, balance sheet by decreasing its current and non-current deferred tax assets by $0.1 million and $11.5 million, respectively and decreasing current deferred tax liabilities by $14.1 million and increasing non-current deferred tax liabilities by $2.5 million.

The significant components of deferred income tax assets and liabilities as of December 31, 2015 and 2014 were as follows:

Total deferred tax liabilities	(171.3		)	(233.4		)
Net deferred tax assets	$	87.7		$	11.2

At December 31, 2015, TCM had $617.3 million in loss and $85.7 million in credit carry-forwards available for tax purposes. The loss and credit carry-forwards per the income tax returns filed, due to uncertain tax benefits, are larger than the carry-forward benefits for which a deferred tax asset is recognized for financial statement purposes. All of the carry-forwards expire beyond 2025.

Valuation allowances are recorded on some of the benefits associated with tax losses, credits and unrealized foreign exchange losses. Historically, a portion of the tax benefits related to TCM's capital expenditures, primarily at Endako Mine and TC Mine, have required us to record valuation allowances as it was not more likely than not that the benefit related to the specific deferred tax assets will be realized based on the available sources of taxable income. As a result of a change in the legal structure in late 2015, which will facilitate future consolidation of our Canadian tax reporting entities, we are able to consider the benefits of these tax planning strategies in the determination of the valuation allowances. The change had a favorable impact on the amount of our deferred taxes that we expect will be realized in the future, resulting in the reversal of $51.6 million of valuation allowances associated with those deferred tax assets.

19. Income and Mining Tax (Benefit) Expense (Continued)

TCM intends to indefinitely reinvest earnings from certain foreign operations. Accordingly, US and non-US income and withholding taxes for which deferred taxes might otherwise be required have not been provided on a cumulative amount of temporary differences (including, for this purpose, any difference between the tax basis in the stock of a consolidated subsidiary and the amount of the subsidiary's net equity determined for financial reporting purposes) related to investments in foreign subsidiaries of approximately $259.6 million and $1,233.5 million as of December 31, 2015 and 2014, respectively. The additional US and non-US income and withholding tax that would arise on reversal of the temporary differences could be offset, in part, by tax credits. Because the determination of the amount of available tax credits and the limitations imposed on the annual utilization of such credits are subject to a highly complex series of calculations and expense allocations, it is impractical to estimate the amount of net income and withholding tax that might be payable if a reversal of temporary differences occurred for the year ended December 31, 2014. As of December 31, 2015, as a result of a change in our legal structure, the company no longer has foreign earnings that would subject to the US foreign tax credit system, making the estimate of foreign repatriated earnings reasonably practical. In the unlikely event of a distribution of US earnings in the form of a taxable dividend subject to withholding, the tax impact could be up to $13.0 million under the reduced treaty rate between Canada and the US.

Income Tax Uncertainties

A summary of the activities associated with TCM's uncertainty in income taxes reserve for unrecognized tax benefits

is as follows:



	Unrecognized Tax Benefits
Balance as of January 1, 2015	$	3.1
Additions for tax positions of current year	57.1
Reductions for tax positions of prior years	(1.9		)
Balance as of December 31, 2015	$	58.3

During 2015, we received $19.8 million in refunds of which $15.9 million was initially accounted for as a net liability for unrecognized tax benefits due to an uncertain tax position primarily related to timing differences for certain deductions. A remaining net liability for unrecognized tax benefits of $9.7 million is presented as other liabilities on TCM's consolidated balance sheets as of December 31, 2015. These refunds did not have an impact on our 2015 tax benefit.

Included in the balance of unrecognized tax benefits at December 31, 2015 are potential benefits of $0.8 million that, if recognized, would affect the effective tax rate on income from continuing operations. Some unrecognized tax benefits are timing in nature and, if recognized, could result in some additional impact to the effective tax rate due to indirect impacts on statutory deductions and valuation allowances. Furthermore, in the next 12 months it is reasonably possible that the unrecognized tax benefits could decrease by $11.3 million as a result of amortization of the tax positions which are timing in nature.

TCM recognizes interest and penalties related to unrecognized tax benefits in operating expenses. During the years ended December 31, 2015 and 2014, TCM recognized $0.3 million and nil, respectively in interest and penalties related to uncertain tax positions.

TCM or one of its subsidiaries files income tax returns in the Canadian federal jurisdiction, US federal jurisdiction and various state and provincial jurisdictions. The tax years for TCM and its significant subsidiaries that remain subject to examination were as follows:

20. Net Loss per Share

The following is a reconciliation of net loss and weighted-average common shares outstanding for purposes of calculating diluted net loss per share for the three years ended December 31, 2015:



	Years Ended December 31,
	2015			2014			2013
Net loss	$	(134.9	)	$	(124.2	)	$	(215.0	)
Basic weighted-average number of shares outstanding	218.8			193.7			171.1
Diluted weighted-average number of shares outstanding	218.8			193.7			171.1
Net loss per share
Basic	$	(0.62	)	$	(0.64	)	$	(1.26	)
Diluted	$	(0.62	)	$	(0.64	)	$	(1.26	)

For the year ended December 31, 2015, TCM was in a net loss position, and approximately 1.1 million stock options, 3.8 million PSUs and 2.7 million RSUs were excluded from the computation of diluted weighted-average shares as the effect would have been anti-dilutive under the treasury stock method.

For the year ended December 31, 2014, TCM was in a net loss position, and approximately 1.3 million stock options, 1.9 million PSUs, 1.5 million RSUs and 26.3 million shares for the settlement of the tMEDS purchase contracts were excluded from the computation of diluted weighted-average shares the effect would have been anti-dilutive under the treasury stock method.

For the year ended December 31, 2013, TCM was in a net loss position, and approximately 2.1 million stock options, 1.2 million PSUs, 1.3 million RSUs and 44.9 million shares for the settlement of tMEDS purchase contracts were excluded from the computation of diluted weighted-average shares as the effect would have been anti-dilutive under the treasury stock method.

21. Transactions with our Endako Mine Joint Venture Partner

Total sales by TCM to Sojitz, TCM's Endako Mine joint venture partner, were $12.1 million, $107.2 million and $80.3 million for the years ended December 31, 2015, 2014 and 2013, respectively. This represented 2.4%, 13.3% and 18.5% of TCM's total revenues for these respective years.

For the year ended December 31, 2015, TCM did not record any significant amounts for management fee income or selling and marketing costs. For the years ended December 31 2014 and 2013, TCM recorded management fee income of $0.4 million and $0.3 million, respectively and selling and marketing commissions of $0.8 million and $0.5 million, respectively, from Sojitz.

At December 31, 2015 TCM did not have any accounts receivable owing from Sojitz. At December 31, 2014, TCM's related accounts receivable owing from Sojitz was $4.1 million.

During 2015, in connection with the assumption of a sale-leaseback described further in Note 8, TCM paid $0.3 million to Sojitz for its 25% share of the fair value of the leased equipment and recognized an additional sale-leaseback obligation of $0.5 million.

23. Concentration of Credit Risk

TCM is exposed to counterparty risk from its cash and cash equivalent balances and its reclamation deposits held by financial institutions and governmental entities. TCM monitors its positions with, and the credit quality of, the financial institutions and companies in which it invests its cash, cash equivalents and that hold its reclamation deposits. Counterparties to cash balances and its reclamation deposits, other than balances maintained in various bank operating accounts, are US and Canadian institutions and the US and Canadian governments.

TCM manages its credit risk from its accounts receivable through its collection activities. As of December 31, 2015, TCM had two customers who owed TCM more than $3.0 million and accounted for approximately 78.9% of total accounts and other receivables outstanding. Another one customer had a balance greater than $1.0 million but less than $3.0 million that accounted for approximately 5.7% of total accounts and other receivables. As of December 31, 2015, all of these customers were compliant with credit terms and scheduled payment dates.

TCM's maximum counterparty and credit risk exposure is the carrying value of its cash and cash equivalents and accounts receivable. The carrying amounts of accounts receivable, accounts payable, accrued liabilities and fixed-rate debt, excluding the 2017 Notes, 2018 Notes, 2019 Notes and tMEDS, as discussed in Note 7, approximate fair value as of December 31, 2015.

24. Segment Information

TCM has three reportable segments, based on products and geography: Copper-Gold, US Operations Molybdenum and Canadian Operations Molybdenum. The Copper-Gold segment represents the Mount Milligan Mine and includes the sale of copper-gold products, net of refining costs and all expenditures, including all mining, milling, on-site general and administration, transportation and warehousing. The US Molybdenum segment includes all US molybdenum sales and tolling and calcining revenue, all Langeloth roasting and on-site general and administration expenditures and all expenditures from TC Mine, which was placed on care and maintenance in December 2014, including all mine site general and administration, molybdenum beneficiation test-work costs, stripping costs and costs for idle mining operations. The Canadian Molybdenum segment which consists of the 75% owned Endako Mine, which was placed on temporary suspension effective December 31, 2014 and care and maintenance effective July 1, 2015, includes 75% of all Canadian molybdenum sales as well as TCM's 75% share of expenditures from the Endako Mine, including all mine site general and administration costs, transportation costs, and costs for idle mining operations. The 2015 costs related to care and maintenance at TC Mine, TCM's 75% share of the temporary suspension and care and maintenance costs at Endako Mine, and TCM's 75% share of the one-time severance costs of $6.7 million relating to the placement of Endako Mine on care and maintenance are reflected in costs for idle mining operations in the statements of operations. The inter-segment represents the elimination of intercompany transactions between the Langeloth Facility and the corporate entity for the year ended December 31, 2015 and the elimination of intercompany transactions between TC Mine, the Langeloth Facility and the corporate entity for the year ended December 31, 2014.

TCM's chief operating decision makers (President and CEO, CFO) evaluate segment performance based on segment revenue less costs and expenses. TCM attributes other income and expenses to the reporting segments if the income or expense is directly related to segment operations, as described above. TCM does not allocate corporate expenditures such as general and administrative, exploration and interest income and expense items to its reporting segments, unless such expenditures are directly related to segment operations. Gains and losses on foreign exchange are calculated on transactions denominated in a different currency than the segment's functional currency; the Copper-Gold segment's unrealized foreign exchange balance is primarily related to its intercompany notes.

Segment information for the three years ended December 31, 2015, 2014 and 2013 was as follows:

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

TCM's disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports that are filed under the Securities Exchange Act of 1934, as amended (the "Exchange Act") is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission, and that such information is accumulated and communicated to TCM's management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. The Chief Executive Officer and the Chief Financial Officer, with assistance from management, have evaluated the effectiveness of disclosure controls and procedures as of December 31, 2015. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded that TCM's disclosure controls and procedures are effective as of December 31, 2015.

Management's Report on Internal Control over Financial Reporting

The management of TCM is responsible for establishing and maintaining adequate internal control over financial reporting. TCM’s internal control over financial reporting is a system designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with US GAAP. TCM’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of its assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with US GAAP, and that its receipts and expenditures are being made only in accordance with authorizations of management and directors; and (iii) provide reasonable assurance regarding prevention and timely detection of unauthorized acquisition, use, or disposition of assets that could have a material effect on its financial statements.

Management assessed the effectiveness of TCM’s internal control over financial reporting as of December 31, 2015 based on the framework set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework 2013. Based on this assessment, management concluded that as of December 31, 2015, TCM’s internal control over financial reporting was effective.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders

Thompson Creek Metals Company Inc.:

We have audited Thompson Creek Metals Company Inc.’s internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Thompson Creek Metals Company Inc.’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Thompson Creek Metals Company Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Thompson Creek Metals Company Inc. and subsidiaries as of December 31, 2015 and 2014, and the related consolidated statements of operations and comprehensive loss, cash flows, and shareholders’ equity for each of the years in the three‑year period ended December 31, 2015, and our report dated February 24, 2016 expressed an unqualified opinion on those consolidated financial statements.
