About Guardian Metal Resources

Guardian Metal Resources PLC (LON: GMET, OTCQX: GMTLF) is a strategic mineral exploration and development company driving the revival of U.S. mined tungsten production and strengthening America's defense metal independence. The Company is advancing two co-flagship tungsten projects, Pilot Mountain, one of the largest undeveloped tungsten deposits in the U.S. and Tempiute, formerly America's largest producing tungsten operation, both located in Nevada, one of the top-rated mining jurisdictions in the U.S. 

In July 2025, Golden Metal Resources (USA) LLC, a wholly-owned subsidiary of Guardian Metal, was awarded US$6.2M from the U.S. Department of War under Title III of the Defense Production Act of 1950 to support the Pilot Mountain pre-feasibility study. The Company has announced plans to pursue a U.S. listing in the first half of 2026. 

Tungsten is a strategic metal essential to the defense, energy transition, technology, and industrial sectors. Against the backdrop of evolving geopolitical dynamics and Chinese export restrictions on tungsten, Guardian is positioned to play the leading role in rebuilding a reliable mined domestic supply chain for this critical defense metal entirely on U.S. soil.
