GMV Minerals completes 16 diamond drill holes at Mexican Hat gold project

VANCOUVER, BC / ACCESS Newswire / July 9, 2026 / GMV Minerals Inc. (the "Company" or "GMV") (TSX-V:GMV)(OTCQB:GMVMF) is pleased to announce that drilling is proceeding well at its Mexican Hat Gold project in SE Arizona. The Company is now drilling its 17 th diamond drill hole with a total of 3,250 meters completed to date. These have been tested over 540 meters of strike length of the deposit, and from surface up to 340 meters depth.

Table 1. List of drill holes completed and sampled, showing assay status. Drilling is progressing well.

To date, nearly 1500 drill samples have been logged, prepped and submitted to the assay lab. Assays are being completed in a timely manner. Pending results have been submitted but not received whereas partial results are where results indicate that mineralization extends farther than expected and additional samples are needed to properly characterize the interval.

The target zones are being encountered as and where expected. Improved understanding of the detailed geology and alteration is being enhanced as more intersections are encountered with additional targets being generated from these results. The planned drilling will test approximately 90% of the mineralization providing confirmation of grade distribution allowing for the Inferred Mineral Resource to be confirmed and potentially be upgraded, and to collect geotechnical information to assist in modelling of the open pit. 2025 PEA Highlights: The Company filed the PEA (as defined below) on September 8, 2025, which included that following 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 a more current price range of US$4,000 per ounce of gold, the project returns a pre-tax IRR of 134.2% (after-tax 104.2%) and a pre-tax NPV at a 5% discount rate of US$1.055 billion (after-tax US$744.4 million). 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/day on a conventional heap leach pad.

Capex: US$89,997,000 (including US$15.4 million contingency). Low LOM Strip Ratio of 2.05 Engineering design analysis indicates the potential to increase pit size and contained ounces with increased gold prices. Technical Report and Qualified Persons The technical report entitled "Updated Preliminary Economic Assessment, Mexican Hat Project" (the " PEA "), with an effective date of August 8, 2025 was prepared by the following Qualified Persons (as defined under NI 43-101), all of whom are independent of the Company: Mr. Brian Olson, Q.P., Samuel Engineering, Inc. (Metallurgical Test Work and Recovery, Process Plant and Process Operating Costs) Mr. Steven Pozder, P.E., Samuel Engineering, Inc. (Project Economics and Infrastructure) Dr. Dave Webb, Ph.D., P.Eng., P.Geo., 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, Data Verification).

Mr. Thomas L. Dyer, P.E., RESPEC LLC. (Mine Design, Production Schedule, Capital and Operating Costs) Mr. Francisco J. Barrios, P.E., BBA Consultants International LP (Pad Design and Loading) Ms. 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.
