About Guardian Metal
Resources
Guardian Metal Resources PLC (NYSE.A: GMTL, LON:GMET, OTCQB:GMTLF)
is a strategic mineral exploration 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
United States.
In July 2025, the U.S. Department of War (DoW) under Title III of
the Defense Production Act of 1950, as amended, invested
US$6.2M in Golden Metal Resources (USA) LLC,
a wholly-owned subsidiary of Guardian Metal Resources
PLC, to support the Pilot Mountain PFS. The Company completed a
U.S. listing on the NYSE American on March 20,
2026.
Tungsten is a strategic metal critical to the defense, energy
transition, technology, and industrial sectors. In the context of
shifting geopolitical dynamics and tightening Chinese export
restrictions, Guardian Metal is well positioned to play a leading
role in re-establishing a secure, domestically mined U.S. supply
chain for this vital defense metal.
