Mt. Hamilton Open Pit Heap Leach Gold-Silver Project

The Mt. Hamilton Project has all major state and federal permits to allow construction of an open pit, heap leach gold-silver project, and has a current mineral resource estimate with an effective date of September 23, 2025 (the "Mt. Hamilton MRE") that was prepared by James N. Gray, P.Geo., of Advantage Geoservices Ltd., out of Vancouver, British Columbia, as set forth below. A technical report for the Mt. Hamilton MRE (the "Mt. Hamilton Technical Report") is being prepared by Advantage Geoservices Ltd., APEX Geoscience Ltd. ("APEX") out of Edmonton Alberta and DRA Americas Inc. on behalf of Mako in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") and will be filed under the Company's SEDAR+ profile at www.sedarplus.ca within 45 days of this news release, and posted on the Company's website at www.makominingcorp.com.

Table 1. Mineral Resource Estimate for the Mt. Hamilton gold-silver deposit with an effective date of September 23, 2025.

1. The MRE was completed by Mr. James Gray, P. Geo, of Advantage Geoservices Ltd.

2. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.

3. Mineral Resources are the portion of the Mt Hamilton deposit that have reasonable prospects of eventual economic extraction by open pit mining method and processed by gold-silver heap leaching.

4. Mineral Resources are constrained oxide and sulfide mineralization inside a conceptual open pit shell. The main parameters for pit shell construction are metal prices of US$2,400/oz gold and US$28/oz silver, variable recovery for gold and silver for oxide and sulfide mineralization by Area, open pit mining costs of US$3.30/ton, heap leach processing costs of US$4.50/ton, general and administrative costs of US$1.65/ton processed, pit slope angles of 50° and a 2.4% royalty.

5. Mineral Resources are shown above a 0.006 oz/ton gold cut-off grade. This is a marginal cut-off grade that generates sufficient revenue to cover conceptual processing, general and off-site costs given metallurgical recovery and long-range metal prices for gold and silver.

6. Units are imperial tons.

7. Numbers have been rounded as required by reporting guidelines and may result in apparent summation differences.

8. Mineral Resources were prepared in accordance with the CIM Definition Standards for Mineral Resources and Mineral Reserves (2014) and CIM MRMR Best Practice Guidelines (2019).

9. The QP is not aware of any known environmental, permitting, legal, taxation, socio-economic, marketing, political or other similar factors which could materially affect the stated Mineral Resources.

The Mt. Hamilton MRE is based on 886 drill holes, totaling 325,960 ft, completed between 1973 and 2012, and is based upon the current interpretation of lithology, structure, and oxidation for the Seligman, Seligman Stock and Centennial areas. Gold ("Au") and silver ("Ag") grades were estimated by Ordinary Kriging, utilizing a block size of 30 x 30 x 15 ft, which is appropriate for an open pit mining operation.

Mt. Hamilton Tungsten Opportunity

The Mt Hamilton Project also hosts a tungsten target, located below and independent of the gold and silver Mt. Hamilton MRE. The tungsten target has been defined by over 100,000 ft of historical exploration drilling. In a report by the Department of the Interior, dated August 25, 2025, tungsten (W) was named as one of the top 10 critical metals listed by their estimated probability-weighted impact of supply disruptions on the U.S. economy. Tungsten is a critical metal for the US Government, especially for national security, defense, and advanced industrial applications.

Mako believes that having a tungsten target located immediately below a permitted gold-silver project enhances its speed to development.

In a historical NI 43-101 Technical Report and Feasibility Study on the Mt. Hamilton Project titled "NI 43-101 Technical Report Feasibility Study Mt. Hamilton Gold and Silver Project, Centennial Deposit and Seligman Deposit White Pine County, Nevada" prepared by SRK Consulting (U.S.) Inc., Report Date October 16, 2014 and Effective Date August 14, 2014 (Re-statement of Reserves), prepared for MH LLC, Solitario Exploration & Royalty Corp. and Ely Gold & Minerals Inc., a reference was made to a historical reserve estimate on the tungsten target at the Mt. Hamilton Project, prepared by Phillips Petroleum Co., as quoted below:

"Phillips Petroleum Co. (Phillips) acquired much of the area of the current Property in 1968 and, between 1968 and 1982, drilled over 100,000 ft in the exploration for tungsten-copper-molybdenum deposits. A study prepared for Phillips in June 1978 quoted an "ore reserve" of 6.2 Mt at a grade of 0.37% WO₃ including 4.2 Mt grading 0.42% WO₃, 0.37% Mo and 0.60% Cu."

This "ore reserve" is an historical estimate and is not being treated as a current mineral resource or mineral reserve. It is provided only to illustrate that there is potential for tungsten-copper molybdenum mineralization on the Mt. Hamilton Project. Neither Advantage, APEX (as defined herein), DRA Americas Inc. nor any Mako qualified persons have reviewed this historical information or done sufficient work to classify the historical estimate as a current mineral resource or mineral reserve under NI 43-101. The Company does not have information on the key assumptions, parameters, and methods used to prepare the historical estimate. The Company is not aware of any more recent estimates or data available in respect of the historical estimate. The Company plans to complete a detailed review of the historical drill core and data to verify the geologic model and mineral resource estimate.

Based on Mako's due diligence on the Mt. Hamilton Project, most of the core historically drilled by Phillips is intact and has been stored in the MH LLC facilities, and Mako plans to undertake further exploration work with the goal of rapidly advancing the tungsten-copper-molybdenum exploration target at the Mt. Hamilton Project.

Akiba Leisman, CEO of Mako states, "the proposed Mt. Hamilton acquisition is a demonstration of how Mako can use all the tools it has available to make highly accretive acquisitions without having to issue equity. The permitted Mt. Hamilton Project is relatively high-grade (for an open pit heap leachable oxide deposit), which is straight down the fairway of the kind of projects our operating team is capable of delivering. All major permits are in place to allow construction and the Company is likely to make a construction decision early next year once it has all available technical information to support such a decision. Furthermore, below the gold and silver mineralization, there is a prospective tungsten-copper-molybdenum target which has been extensively drilled by previous operators. Given the strategic importance of tungsten, it will be a key objective to rapidly advance this target to help address the supply needs of the United States."

Transaction 1: Sailfish Acquisition of MH LLC

Sailfish will acquire 100% of MH LLC from arm's length party Mt. Hamilton Holdings LLC for a total purchase price of US$40.0 million in cash. Sailfish has received a commitment letter for a US$40 million non-revolving bridge finance facility (the "Wexford-Sailfish Loan") from affiliates of Wexford Capital LP ("Wexford"), the controlling shareholder of both Mako and Sailfish, to fund the cash component of the acquisition. Mako is not a party to the Wexford-Sailfish Loan and will not incur any direct payment obligations or liabilities in connection with such loan. Upon completion of this initial acquisition transaction, Mako has agreed to take over control of the Mt. Hamilton Project and all costs associated therewith, which costs are not anticipated to be material, and work expeditiously with Sailfish to complete the acquisition of MH LLC from Sailfish. For further information, please refer to Sailfish's news release issued on September 30, 2025, which is available on its SEDAR+ profile at www.sedarplus.ca.

Transaction 2: Sale of MH LLC to Mako in exchange for Stream and NSR royalty

The Term Sheet between Sailfish and Mako provides for the transfer of 100% of MH LLC to Mako in exchange for consideration consisting of the Stream and NSR royalty.

Under the terms of the Stream, Sailfish will purchase from Mako approximately 341.7 troy ounces of gold per month at a price of 20% of the London Bullion Market Association PM Fix price for a period of 60 months (the "Stream Period") commencing immediately following the closing of this second acquisition transaction.

Although production supporting delivery of gold during the majority of the Stream Period is expected to be from the Mt. Hamilton Project, Mako will have the right to source monthly mineral deliveries from its other projects as well as by way of the purchase of silver and/or gold credits or the delivery of gold equivalent ounces. The number of troy ounces of gold to be purchased by Sailfish will be subject to adjustment pursuant to a put/call structure whereby the monthly stream amount will be adjusted, if necessary, to ensure that the stream amount consists of such number of troy ounces of gold of no less than the net equivalent margin of US$738,000.00, which is equivalent to US$2,700/oz Au and no more than the net equivalent margin of US$1,011,333.33, which is equivalent to US$3,700/oz Au. Upon completion of the Stream Period, Mako will grant Sailfish the NSR royalty on all mineral production with respect to the Mt. Hamilton Project.

Mako and Sailfish will enter into a definitive purchase agreement in connection with completing the acquisition, which shall contain certain conditions precedent including, but not limited to, obtaining all required special committee and board approvals for the transaction, disinterested approval of the shareholders of each of Mako and Sailfish to be obtained at respective special meetings of shareholders, and all required approvals including the approval of the TSX Venture Exchange. In the event that the requisite shareholder and/or regulatory approvals for the transaction are not received and the definitive agreement is terminated, Wexford, or a nominee thereof, will purchase MH LLC and the Mt. Hamilton Project, including all rights, obligations and liabilities in connection therewith, with the exception of any costs or liabilities incurred by Mako from the date Mako took over control of the Mt. Hamilton Project to the completion of the sale to Wexford which are not anticipated to be material (the "Fallback Sale"). The purchase price for the Fallback Sale shall be equal to the then outstanding principal and interest amount owing by Sailfish to Wexford under the Wexford-Sailfish Loan and is expected to be settled by a triparty offset arrangement amongst Mako, Sailfish and Wexford, following which Mako will have no outstanding payment obligations or liabilities to either Sailfish or Wexford in connection with the transaction. In the event of a Fallback Sale, the Stream and Royalty Agreement will be rescinded without the secured Stream or NSR royalty having come into force or effect, and there will be no ongoing obligations or liabilities of Mako to Sailfish thereunder.

Mt. Hamilton Project - Property Description and Geology

The Mt. Hamilton Project includes private land and unpatented mining claims on federal land, and is controlled through direct ownership and through lease agreements, totaling approximately 4,530 acres. Most of the federal land, including the land containing the Mt. Hamilton MRE, is administered by the U.S. Forest Service, an agency of the U.S. Department of Agriculture, while the balance is administered by the United States Bureau of Land Management, an agency of the U.S. Department of the Interior.

Mineralization at the Mt. Hamilton Project is characterized by an early polymetallic tungsten-copper-molybdenum plus gold-silver skarn-related phase, and a late gold-silver epithermal overprint. Gold-silver mineralization at Mt. Hamilton occurs within a broad north trending zone of anomalous gold-silver and is hosted in three contiguous areas known as Seligman, Seligman Stock and Centennial. Combined mineralization spans an area approximately 5,800 ft long and 2,000 ft wide, and ranges from exposed at surface to 730 ft below surface.

High and low-angle faults, along with skarn assemblages developed along lithologic contacts, are the main controls to gold-silver mineralization. Gold occurs as free gold, in association with sulfide minerals (pyrite and arsenopyrite), and oxide minerals (hematite and goethite), disseminated with clay, and encapsulated within quartz (Paster; 1988, 1989, and 1990).

These geological descriptions as well as additional technical information will be in the Mt. Hamilton Technical Report containing the Mt. Hamilton MRE.
