Midway Gold Files Technical Report for Updated Resource at Spring Valley Project, Nevada

Midway Gold Corp. ("Midway" or the "Company") (MDW:TSX, MDW:NYSE-MKT) announces that it has filed a technical report (“the report”) entitled “NI 43-101 Technical Report on Resource, Spring Valley Project” dated September 9, 2014. The report, by Gustavson Associates, LLC, was prepared in accordance with National Instrument 43-101 in support of the Company's August 12, 2014 news release. The August announcement detailed a measured, indicated and inferred mineral resource estimate for its Spring Valley Project in Pershing County, Nevada. The mineral resource estimate is summarized in Table 1 and provides a reference to growth from the 2011 estimate. The technical report can be found under the Company’s profile on SEDAR, available at www.sedar.com.

Note: The tonnage and total ounces of gold for resources were determined from the statistical block model. Average grades were calculated from the tonnage and total ounces and then rounded to the significant digits shown. Calculations based on this table may differ due to the effect of rounding.

1Resources as per Independent NI 43-101 Technical Report by Gustavson Associates, LLC (May 2011). The calculation uses a cutoff grade of 0.14 g/t. An updated report “Updated NI 43-101 Technical Report on the Spring Valley Project, Pershing County, Nevada” dated November 29, 2012 was filed to clarify responsibilities of the Qualified Persons and to clarify language regarding capping, density, and cut-off values. This updated report made no changes to the resource estimate.

2The Mineral Resource Estimate was prepared by Gustavson Associates, LLC of Lakewood, Colorado. The estimate uses a cutoff grade of 0.14 g/t. Gustavson completed the open pit mineral resources, with Zachary Black and Donald E. Hulse acting as the Qualified Persons.

Whittle Pit-Defined Spring Valley Resources

The 2014 mineral resource estimate was further analyzed by a Whittle pit optimization program to determine the portion of the resource which has the potential to be mined by open pit methods based upon the current level of resource development. Open pit models were generated at gold prices ranging between $1,100/oz and $1,700/oz in $200/oz increments. The results are listed below in Table 2. The $1,500/oz pit model was selected as the base case due to a 3-year trailing average gold price of $1,543.83/oz. Please refer to the technical report filed today on SEDAR for more information.

Note: The mineral resource was estimated using Leap Frog Kriging Grade Shell Estimation routine for domain definition and the Ordinary Kriging estimation algorithm. Whittle pit optimization was used to determine potentially mineable tonnage. Measured, indicated and inferred mineral classification was determined by the variography of each mineral domain. A complete description of the modeling method, environmental and other project risks can be found in the full technical report. Mineral resources are not mineral reserves; resources have no engineered economic viability and should not be considered economic to mine.

Spring Valley Project, Nevada

Spring Valley is a large porphyry-hosted gold system located about 20 miles northeast of Lovelock in Pershing County, Nevada. Barrick achieved their earn-in by spending $38 million to earn a 70 percent interest in the project (see February 24, 2014 press release). The project is now run as a joint venture with Barrick as manager. Midway converted its 30% interest into a 25% free-carried interest in Spring Valley and will be carried to production, at which point Midway will pay back its share of development capital from production.

Barrick’s 2014 project budget is $17.4 million, which includes $9 million for continued in-fill drilling and $8.4 million for preparation of an internal pre-feasibility study and other related project development expenditures. Planned development activities will include additional metallurgical studies, hydrological studies, environmental baseline studies, and geotechnical wall rock stability studies required for mine planning.

Forward looking statements are statements that are not historical facts and include, but are not limited to, statements about the Company's intended work plans and resource estimates, including plans for the further development of the Spring Valley Project and plans for a preliminary economic assessment in relation to the Spring Valley Project. Forward-looking statements are typically identified by words such as: “may”, “should”, “plan”, “believe”, “predict”, “expect”, “anticipate”, “intend”, “estimate”, postulate” and similar expressions or the negative of such expressions or which by their nature refer to future events. The forward-looking statements in this press release are subject to various risks, uncertainties and other factors that could cause the Company's actual results or achievements to differ materially from those expressed in or implied by forward looking statements. These risks, uncertainties and other factors include, without limitation, risks related to the timing and completion of intended work plans, risks related to fluctuations in gold prices; uncertainties related to raising sufficient financing to fund the planned work in a timely manner and on acceptable terms; changes in planned work resulting from weather, logistical, technical or other factors; the possibility that results of work will not fulfill expectations and realize the perceived potential of the Company's properties; uncertainties involved in the interpretation of drilling results and other tests and the estimation of gold resources and reserves; the possibility that required permits may not be obtained on a timely manner or at all; the possibility that capital and operating costs may be higher than currently estimated and may preclude commercial development or render operations uneconomic; the possibility that the estimated recovery rates may not be achieved; risk of accidents, equipment breakdowns and labor disputes or other unanticipated difficulties or interruptions; the possibility of cost overruns or unanticipated expenses in the work program; changes in interest and currency exchanges rates; local and community impacts and issues; environmental costs and risks; and other factors identified in the Company's SEC filings and its filings with Canadian securities regulatory authorities.

Cautionary note to U.S. investors concerning estimates of reserves and resources: This press release and the documents referenced in this press release use the terms “reserve" and "mineral resource“, which are terms defined under Canadian National Instrument 43-101 and the Canadian Institute of Mining and Metallurgy Classification system. Such definitions differ from the definitions in U.S. Securities and Exchange Commission ("SEC") Industry Guide 7. Under SEC Industry Guide 7 standards, a "final" or "bankable" feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority. Mineral resources are not mineral reserves and do not have demonstrated economic viability. The SEC normally only permits issuers to report mineralization that does not constitute SEC Industry Guide 7 compliant "reserves" as in-place tonnage and grade without reference to unit measures. The references to a “resource” in this press release and the documents referenced in this press release are not normally permitted under the rules of the SEC. It cannot be assumed that all or any part of mineral deposits in any of the above categories will ever be upgraded to Guide 7 compliant reserves. Accordingly, disclosure in this press release and in the technical reports referenced in this press release may not be comparable to information from U.S. companies subject to the reporting and disclosure requirements of the SEC.
