assumptions, and estimates contained in the Mexican Hat PEA and GMV ’s news release dated August 13 th ,
2025.
Highlights:
• The Base Case generates a pre -tax Internal Rate of Return (“IRR”) of 66.1% (after -tax 50.2%) and a pre -tax
net present value (“NPV”) at a 5% discount rate of US$390.2 million (after -tax US$268.3 million) with a 1.53
year payback (1.82 year after-tax) of invested capital using a US$2,500 per ounce gold price.
• Based on price sensitivity analysis at approximately the current price of US$3,350 per ounce of gold, the project
returns a pre-tax IRR of 106.8% (after-tax 82.5%) and a pre-tax NPV at a 5% discount rate of US$767 million
(after-tax US$538.1 million) with a payback period of 1.10 years (1.3 years after-tax).
• The Base Case mine life is 10 years with total production of 597,841 ounces, averaging approximately 60,000
ounces per year.
• Crushed mineralized material will be conveyor stacked at a rate of approximately 10,000 tonnes/day on a
conventional heap leach pad.
• Capex: US$89,997,000 (including US$15.4 million contingency).

275655.00008/316000537.3
• Opex: US$788 million LOM with low LOM Strip Ratio of 2.05.
• Estimated cash cost of production is US$1,354 per ounce with an all -in-sustaining cost of $1,545 per ounce
inclusive of sustaining capital and additional overhead support.
2025-2026 Forward Looking Plan
The Mexican Hat PEA economics justify continued investment in project development. The forward -looking
plan for Mexican Hat includes work required to advance the project through to a feasibility study and into the
permitting process.
These tasks include:
• Approx. 7000 meters of in -fill drilling to increase confidence in the current geological understanding
and Mineral Resource estimation to sufficient level to support Mineral Reserve development
• Metallurgical column, hardness, and grinding tests to further optimize and improve heap leach gold
recovery, and to provide information for feasibility design work
• Performing a trade-off study for self-mining and crushing versus contract mining and crushing
• Geotechnical drilling and analysis to optimize pit slope design parameters
• Conduct base-line water sampling, and update of hydrologic, cultural, and environmental studies for
permitting
Incentive Stock Options
In addition, the Company announces that subject to TSX Venture Exchange approval, it has granted incentive
stock options to various directors, officers, and consultants to purchase up to 1,325,000 common shares
exercisable at a price of $0.30 per share. The options will be exercisable for a period of five years from the date
of issuance.

PEA Information and Cautionary Note Regarding Inferred Mineral Resources
The mine plan evaluated in the Mexican Hat PEA is preliminary in nature and include s Inferred Mineral
Resources, as defined by NI 43 -101 that are considered too speculative geologically to have the economic
considerations applied to them that would enable them to be converted to Mineral Reserves. Mineral Resources
that are not Mineral Reserves do not have demonstrated economic viability. Additional drilling and technical
studies will need to be completed in order to fully assess its viability. There is no certainty that a production
decision will be made to develop the Mexican Hat Project or that the economic results described in the Mexican
Hat PEA will be realized. Mine design and mining schedules, metallurgical flow sheets and process plant designs
will require additional detailed work and economic analysis and internal studies to ensure satisfactory
operational conditions and decisions regarding future targeted production.
Cautionary Note to U.S. Investors
The United States Securities and Exchange Commission permits U.S. mining companies, in their filings with
the SEC, to disclose only those mineral deposits that a company can economically and legally extract or
produce. We use certain terms in this report, such as " Measured," "Indicated," "Inferred," and " Resources,"
that the SEC guidelines strictly prohibit U.S. registered companies from including in their filings with the SEC.
