GMV Minerals Inc. (the ‘Company’ or ‘GMV’) (TSXV:GMV)(OTCQB:GMVMF) is pleased to announce positive results from the updated Preliminary Economic Assessment (‘PEA’) study of the Mexican Hat Gold Project (the ‘Mexican Hat Project’), located in Cochise County, southeastern Arizona.

A National Instrument 43-101 –Standards of Disclosure for Mineral Projects (‘NI 43-101’) compliant technical report (the ‘Report’) entitled ‘Updated NI 43-101 Technical Report Preliminary Economic Assessment, Mexican Hat Project’ with an effective date of August 8, 2025 will be filed on SEDAR+ at www.sedarplus.ca under the Company’s profile within 45 days of this news release. All amounts are stated in second quarter 2025 US dollars (US$).

The Mexican Hat hosts a shallow oxide gold resource with excellent metallurgy and high recoveries, supported by a low strip ratio and minimal pre-stripping. Infrastructure is in place and the Mexican Hat Project demonstrates a robust NPV and IRR. With fast leach kinetics and low reagent consumption, the Company believes the Mexican Hat Project offers exceptional potential economics.

Highlights:

• 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).

• 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).

• 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.

• Engineering design analysis indicates the potential to increase pit size and contained ounces with increased gold prices.

Initial capital expenditures are estimated at US$89,997,000 million as detailed below:

OPERATING COSTS

The mine operating costs were calculated to average $3.49 per tonne mined as summarized below.

The life-of-mine operating costs were calculated to average US$20.44/tonne resource processed as summarized below.

MINERAL RESOURCES

An updated Mineral Resource Estimate prepared by DRW Geological Consultants Ltd., with an effective date of August 8, 2025, was used in the PEA. Details of the Mineral Resource Estimate can be found in the Report to be filed on SEDAR+ within 45 days of this release.

• The Mineral Resource Estimate has been constrained to a preliminary optimized pit shell, using the following parameters: SG = 2.57 gm/cc based on testwork, mining costs = $3.00/tonne, mining recovery = 98%, mining dilution = 2%, process cost = $5.00 per tonne, G&A = $1.05 per tonne, gold price = $2,500 per troy ounce, throughput at 10,000 tpd., discount rate = 5%. A cost of $0.03 was added per bench to the mining cost below the existing level surface.
• A top cut of 32 gpt gold is applied to all zones except Zone 6 which has a top cut of 50 gpt gold.
• Mineral Resources have been calculated using the Inverse Distance Squared method.
• Mineral Resources constrained to optimized pit shells are not Mineral Reserves and do not have demonstrated economic viability.
• Conforms to NI 43-101, Companion Policy 43-101CP, and the CIM Definition Standards for Mineral Resources and Mineral Reserves. Inferred Resources have been estimated from geological evidence and limited sampling and must be treated with a lower level of confidence than Measured and Indicated Resources.
• All numbers are rounded. Overall numbers may not be exact due to rounding.
• There are no known legal, political, environmental, or other risks that could materially affect the potential development of the mineral resources.

MINE PLAN

The mine plan is conceived as a conventional open pit tuck and shovel/loader operation. There are two independent pits which are developed with five-phase or pushback designs. Pit shells were designed using 6.0-meter benches with a catch bench installed every 18 meters. A bench face angle of 66° was used, resulting in an inner-ramp angle of 45° when catch benches were included. An 88% overall gold recovery has been used in this study, which was based on bottle roll and column leach test results. Base case haulage ramps are 26 meters wide and have a design gradient of 10%. Processing rates are based on a daily crushing rate of approximately 10,000 tonnes per day utilizing two stage crushing

The mine and crushing will be operated by contractors with oversight by GMV mine management. The mine plan produces a nominal tonnage to the crushing and heap leach of 3,500 Ktonnes per year (10,000 tpd) from a total material movement of 93.8 Ktonnes for the life of mine (26,106 tpd LOM average).

The PEA is preliminary in nature; it includes inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that the PEA will be realized. There is no Mineral Reserve at the Mexican Hat Project at this time. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Over the course of the mine life, 38.6 Mtonnes of Mineralized Resource is planned for processing out of a total material movement of 117.8 Mtonnes.

INFRASTRUCTURE & PROCESS PLANT

The Mexican Hat Project is located in the southeastern part of the State of Arizona, approximately 72 miles east-southeast of Tucson, and can be accessed from the Old Ghost Town Road., a gravel road extending south of the Town of Pearce or north from Gleeson Road.

Groundwater will be used as the source of water for mining operations. No permitting restrictions or quantity issues are anticipated.

A 69 kV powerline to site will be supplied by Sulphur Springs Valley Electric Cooperative from their power plant located 30 km north of the project site.

The crushing plant will be operated by a contractor to produce a crushed product for heap leaching with a 25 mm top size. Pregnant solution from the heap leach will be processed in a conventional adsorption desorption recovery (ADR) plant. The process plant will produce doré gold bars.

Today’s crypto news to know

World Liberty Financial sets up US$1.5 billion crypto treasury

World Liberty Financial, a digital asset venture backed by US President Donald Trump and his sons, has announced plans to establish a US$1.5 billion “crypto treasury” in partnership with ALT5 Sigma (NASDAQ:ALTS).

Under the deal, ALT5 will raise US$1.5 billion through the sale of its own shares. The funds will go toward the purchase of World Liberty’s in-house token, $WLFI, and will also be used to set up a crypto treasury, settle litigation, pay down debt and for other corporate uses. It will ultimately hold about 7.5 percent of $WLFI tokens.

Unnamed institutional investors and venture capital firms participated in the share sale. Crypto treasury models have grown in popularity this year amid a friendlier US regulatory stance under the Trump administration.

The project’s leadership is heavily tied to the Trump family, with Trump himself listed as “co-founder emeritus,” and Eric, Donald Jr. and Barron Trump holding co-founder titles.

As part of the arrangement, Eric Trump will join ALT5’s board and Zach Witkoff will serve as its chair.

Bullish shares surge on NYSE debut

Bullish (NYSE:BLSH), the parent company of Bullish Exchange and CoinDesk, began trading on the New York Stock Exchange on Wednesday. Shares were priced at US$37 each, an increase from an earlier target of US$33, with 30 million on offer to raise US$1.1 billion and value the company at nearly US$5.4 billion.

Shares surged as much as 218 percent to reach US$118 on trading volume of roughly 38 million shares, before pulling back to close at US$70.65. The initial public offering pushed the company’s market cap above US$10 billion.

Banking groups push for stablecoin loophole closure

US banking groups, led by the Bank Policy Institute (BPI), are urging Congress to close a loophole that allows stablecoin issuers to indirectly offer yields through affiliates. They argue that while new stablecoin laws prevent issuers from directly offering yield, they don’t prohibit crypto exchanges or affiliated businesses from doing so.

The groups contend that this circumvents the law and could lead to a US$6.6 trillion outflow of deposits from traditional banks, potentially disrupting credit flow to American businesses and families.

Banks are concerned that yield-bearing stablecoins undermine their ability to attract deposits, which are crucial for backing loans. The offering of yield is a significant marketing draw for stablecoins, with some, like USDC, already rewarding holders on exchanges such as Kraken and Coinbase (NASDAQ:COIN).

Safe harbor programs proposed for DeFi

In a Wednesday letter, Andreessen Horowitz (a16z) and the DeFi Education Fund asked the US Securities and Exchange Commission (SEC) and Hester Peirce, head of the commission’s Crypto Task Force, to set up a safe harbor program from broker-dealer registration requirements for non-fungible token (NFT) and DeFi applications.

The group said the letter was a follow up to Trump’s Working Group on Digital Assets, which called on the SEC to give certain DeFi service providers relief from registration provisions under the Exchange Act, specifically those related to broker-dealers, exchanges and clearing agencies. SEC Chair Paul Atkins also directed staff to update “antiquated agency rules and regulations” for certain crypto and blockchain applications in July.

To avoid enforcement actions, a safe harbor provision would exempt some companies that offer crypto-related products and services from enforcement actions. a16z has sent two previous letters to the commission this year recommending safe harbors for NFTs, airdrops and network tokens.

1. Teck Resources (TSX:TECK.A,TSX:TECK.B)

Market cap: C$22.01 billion
Share price: C$45.04

Teck Resources is a major global polymetallic miner, as well as one of the world’s top zinc producers.

The Vancouver-headquartered company produced 615,900 metric tons (MT) of zinc in concentrate in 2024, with 555,600 MT coming from its Red Dog zinc mine in Alaska. The remaining 60,300 MT came from Teck’s 22.5 percent share of zinc production from the Peru-based Antamina copper-zinc mine.

Teck’s total 2025 production guidance for the base metal is set in a range of 525,000 to 575,000 MT. As of June 30, the company’s zinc production for the year totaled 384,000 MT.

In addition to the sites mentioned, Teck owns the Trail operations, which it describes as ‘one of the world’s largest fully integrated zinc and lead smelting and refining complexes.’ Located in BC, Canada, the Trail operations produced 256,000 MT of refined zinc in 2024, with 190,000 to 230,000 MT of the material expected in 2025.

Teck pays a quarterly dividend. On September 29, it will pay out a dividend of C$0.125 per share.

2. Fireweed Metals (TSXV:FWZ)

Market cap: C$485.11 million
Share price: C$2.32

Fireweed Metals is a critical metals company whose flagship Macmillan Pass zinc project is located in Canada’s Yukon. In 2023, the company acquired the Gayna River zinc project in the Northwest Territories, as well as the Mactung tungsten project, which is adjacent to Macmillan Pass and straddles the border between Yukon and the Northwest Territories. According to Fireweed, Mactung ‘hosts the world’s largest high-grade tungsten deposit.’

Even with these new assets, the company still has a strong focus on Macmillan Pass. In fact, in November 2023, the Fireweed team, led by Dr. Jack Milton, the firm’s vice president of geology, received the Association for Mineral Exploration’s H.H. “Spud” Huestis Award for its work at the Macmillan Pass property.

Fireweed’s best drill intersection to date from Macmillan Pass’ Boundary zone includes 143.95 meters true width at 14.45 percent zinc, including 28.71 meters at 25.52 percent zinc. In September 2024, after its largest regional exploration campaign ever at Macmillan Pass, the company released an updated resource estimate for the Tom and Jason deposits, as well as inaugural resource estimates for the Boundary zone and End zone deposits.

Fireweed launched its 2025 field program in early June, saying it will include 12,000 meters of diamond drilling at Macmillan Pass. The work will target ‘both high-priority regional prospects and step-outs around known zinc-lead-silver-gallium-germanium deposits,’ according to a press release.

3. Trilogy Metals (TSX:TMQ)

Market cap: C$405.68 million
Share price: C$2.47

Trilogy Metals is focused primarily on copper, zinc and cobalt at its Alaskan Upper Kobuk projects, which are held by Ambler Metals, a joint venture operating company owned equally by Trilogy and South32 (ASX:S32,OTC Pink:SHTLF).

Its most advanced zinc project is the Arctic copper-zinc-lead-gold-silver volcanogenic massive sulfide project, which is in the feasibility stage and has proven and probable reserves of 43.44 million MT grading 3.12 percent zinc.

In addition, early stage 2023 field work at the company’s wholly owned Helpmejack project in Alaska’s Ambler schist belt outlined two target areas prospective for volcanogenic massive sulfide and shale-hosted zinc deposits.

Trilogy had been focusing on improving access to the region with its Amber Access project, but it was rejected by the US Bureau of Land Management under the Biden administration in June 2024 due to the impact the proposed road could have on the environment and communities in the region, which have seen little development.

However, under the Trump administration, a series of executive and secretarial orders focusing on developing Alaska’s natural resources have been enacted that could reverse this decision.

“Recent actions taken by President Donald Trump and Interior Secretary Doug Burgum signal a positive path forward for the Ambler Road,’ Trilogy Metals President and CEO Tony Giardini said. ‘This transportation corridor is crucial not only for providing access to the minerals that are vital to U.S. national security and prosperity, but also for much-needed economic growth and job creation in Alaska. Trilogy Metals is committed to working with all stakeholders on progressing the road, to unlock the vast natural resource potential of the Ambler Mining District.”

4. Emerita Resources (TSXV:EMO)

Market cap: C$317.02 million
Share price: C$1.20

Emerita Resources has a portfolio of high-grade, large-scale polymetallic projects covering more than 26,000 combined hectares in Spain’s Iberian Pyrite Belt. The company’s flagship asset is the Iberian Belt West project, which hosts three massive sulfide deposits: La Infanta, La Romanera and El Cura.

Emerita released a resource estimate for Iberian Belt West in May 2023. It finished environmental baseline studies the following month, and completed supporting documentation for its mining license application in December 2023.

In July 2024, the Andalusian government granted Iberian Belt West a declaration of strategic interest, which will streamline the process of moving the project through development.

Phase 2 metallurgical testing results for the La Romanera and La Infanta deposits released in late 2024 show that commercial-grade copper, lead and zinc concentrates can be obtained from both deposits.

In March of this year, Emerita announced an updated resource estimate for Iberian Belt West, showing a 35 percent increase to the total indicated mineral resource tonnage and a 44 percent increase in total inferred mineral resource tonnage. Also this year, Emerita made the cut for the latest TSX Venture 50 list.
