About Guardian Metal Resources

Guardian Metal Resources PLC (LON: GMET, OTCQB: GMTLF, NYSE A: GMTL) is a U.S.-focused exploration-stage company focused on tungsten in Nevada, United States. Its principal tungsten asset is the Pilot Mountain project, followed by the Tempiute project, which are both situated in historic tungsten districts with well-known occurrences of mineralization that have seen prior tungsten mining activity by third parties.

In July 2025, the U.S. Department of War (DoW), under Title III of the Defense Production Act of 1950, as amended, invested US$6.2 million in Golden Metal Resources (USA) LLC, a wholly-owned subsidiary of Guardian Metal Resources PLC, to support the Pilot Mountain PFS. The Company completed an initial public offering of American Depositary Shares in the United States in March 2026.

Tungsten is used across defense, energy transition, technology and industrial applications. The Company's projects are located in the United States and are focused on potential future development.
