Guardian Metal Resources PLC

We are a U.S.-focused exploration-stage critical minerals company with a portfolio of tungsten and polymetallic exploration projects located in the State of Nevada. Our 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 scheelite-bearing skarn mineralization that have seen prior tungsten mining activity by third parties. In addition, we hold early-stage copper, gold, silver and lithium exploration properties, which we believe provide optionality and exposure to broader critical-minerals thematic trends.
