Guardian Metal Resources plc published the Technical Report Summary for its Pilot Mountain tungsten project on August 27, 2026. The filing supports the company’s Pre-Feasibility Study results announced on June 30, 2026, and complies with S-K 1300 standards.

Regulatory Compliance

The Technical Report Summary validates the technical and economic assumptions of the Pre-Feasibility Study. Guardian Metal prepared the document in accordance with S-K 1300 regulations, which govern mineral resource reporting for companies listed on U.S. exchanges.

The company listed the report on its website for investor review. This publication marks a key regulatory milestone for the Nevada-based project, one of the largest undeveloped tungsten deposits in the United States.

Strategic Context

Guardian Metal focuses on reviving U.S. mined tungsten production to strengthen defense metal independence. The company advances two co-flagship projects in Nevada: Pilot Mountain and Tempiute, formerly a major producing operation.

In July 2025, the U.S. Department of War invested US$6.2M in Golden Metal Resources (USA) LLC, a wholly-owned subsidiary of Guardian Metal. The investment supported the completion of the Pilot Mountain Pre-Feasibility Study under Title III of the Defense Production Act of 1950.

Guardian Metal completed its listing on the NYSE American on March 20, 2026. The company cites shifting geopolitical dynamics and Chinese export restrictions as drivers for establishing a secure domestic supply chain for this critical defense metal.

Guardian Metal Resources plc (NYSE.A:GMTL)(LON:GMET)(OTCQB:GMTLF) has secured £1,595,610.80 through the exercise of warrants over 3,989,027 new ordinary shares of 1 pence each. The company announced on August 17, 2026, that it received notice to exercise these warrants at a price of 40 pence per share, providing fresh capital for its strategic exploration activities focused on tungsten in Nevada, USA.

The warrant exercise relates to a strategic financing raise previously announced on August 15, 2024. Following this transaction, only 100,000 warrant shares remain on the register. These residual warrants also carry an exercise price of 40 pence per share and expire on January 25, 2027. They are associated with Tempiute's Definitive Exploration Lease and Option to Purchase Agreement, as disclosed in January 2025.

Admission and Share Capital

Application will be made for the 3,989,027 warrant shares to be admitted to trading on AIM, with admission expected on or around August 20, 2026. The new shares will rank pari passu in all respects with the ordinary shares currently traded on AIM.

Upon admission, Guardian Metal's issued share capital will comprise 198,797,008 ordinary shares of 1p each. This figure represents the total voting rights in the company and serves as the denominator for shareholders calculating their notification requirements under the Financial Conduct Authority's Disclosure and Transparency Rules.

What the Numbers Show

The completion of this warrant exercise significantly reduces the potential dilution pressure from existing warrants, leaving only 100,000 shares outstanding against the newly issued 3,989,027. This move consolidates the capital base ahead of further exploration phases at its Pilot Mountain and Tempiute projects.

Strategic Context

Guardian Metal is advancing two co-flagship tungsten projects: Pilot Mountain, one of the largest undeveloped tungsten deposits in the US, and Tempiute, formerly one of America's largest producing tungsten operations. Both are located in Nevada.

In July 2025, the U.S. Department of War (DoW) invested US$6.2M in Golden Metal Resources (USA) LLC, a wholly-owned subsidiary of Guardian Metal, under Title III of the Defense Production Act of 1950. This investment supported the recently completed Pilot Mountain PFS. The company completed its US listing on the NYSE American on March 20, 2026.
