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 includes 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.
