GMV MINERALS SIGNS MULTI YEAR LAND LICENSING AGREEMENT

GMV Minerals Inc. has signed an amended multiyear land licensing agreement with the Kay B. Graham Revocable Trust (a local ranching family) authorizing GMV to access the surface estate of certain Graham family ranch lands to conduct exploration-drilling-related activities.

The amendment also provides GMV with continuing authorization to operate a weather station and collect weather-related data and observations and to collect long-term water quality and quantity information from water monitoring wells.

2025 PEA (preliminary economic assessment) highlights

The company filed the PEA (as defined below) on Sept. 8, 2025, which included that following highlights:

• The base case generates a pretax internal rate of return (IRR) of 66.1 per cent (after tax: 50.2 per cent) and a pretax net present value at a 5-per-cent discount rate of $390.2-million (U.S.) (after-tax: $268.3-million (U.S.)) with a 1.53-year payback (1.82 years after tax) of invested capital using a gold price of $2,500 (U.S.) per ounce;
• Based on a price sensitivity analysis at approximately the current price of $4,000 (U.S.) per ounce of gold, the project returns a pretax IRR of 134.2 per cent (after tax: 104.2 per cent) and a pretax NPV at a 5-per-cent discount rate of $1,055-million (U.S.) (after tax: $744.4-million (U.S.));
• Base-case mine life of 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 per day on a conventional heap-leach pad;
• Capex (capital expenditure): $89,997,000 (U.S.) (including $15.4-million (U.S.) contingency);
• Low LOM (life-of-mine) strip ratio of 2.05;
• Engineering design analysis indicates the potential to increase pit size and contained ounces with increased gold prices.

About GMV Minerals Inc.

GMV Minerals is a publicly traded exploration company focused on developing precious metal assets in Arizona. GMV, through its 100-per-cent-owned subsidiary, has a 100-per-cent interest in a mining property lease commonly referred to as the Mexican Hat property, located in Cochise county, Arizona, United States. The project was initially explored by Placer Dome (USA) in the late 1980s to early 1990s. GMV is focused on developing the asset and realizing the full mineral potential of the property through near-term gold production. The company's National Instrument 43-101 resource estimate (inferred) is 36,733,000 tonnes grading 0.58 gram per tonne gold at a 0.2-gram-per-tonne cut-off, containing 688,000 ounces of gold, with an effective date of Aug. 8, 2025.

Technical report and qualified persons

The technical report, entitled "Updated Preliminary Economic Assessment, Mexican Hat Project," with an effective date of Aug. 8, 2025, was prepared by the following qualified persons (as defined under NI 43-101), all of whom are independent of the company:

• Brian Olson, qualified person, Samuel Engineering Inc. (metallurgical test work and recovery, process plant, and process operating costs);
• Steven Pozder, PE, Samuel Engineering (project economics and infrastructure);
• Dr. Dave Webb, PhD, PEng, PGeo, DRW Geological Consultants Ltd. (mineral resource estimate, mineral reserve estimate, property description and location, accessibility, climate, local resource, infrastructure and physiography, history, geological setting and mineralization, deposit types, exploration, drilling, sample preparation, analysis and security, and data verification);
• Thomas L. Dyer, PE, Respec LLC (mine design, production schedule, capital and operating costs);
• Francisco J. Barrios, PE, BBA Consultants International LP (pad design and loading);
• Dawn Garcia, CPG, PG, Stantec Consulting Services Inc. (environmental).

Technical information and cautionary note regarding inferred mineral resources

The mine plan evaluated in the 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 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. Key assumptions, qualifications and estimates to the results of the PEA are contained in the PEA.

Dr. D.R. Webb, PhD, PGeo, PEng, is the qualified person for this release within the meaning of NI 43-101 and has reviewed the technical content of this release and has approved its content.
