Guardian Metal Resources could begin construction preparations at its Pilot Mountain tungsten project as early as August next year, based on the findings of a new prefeasibility study (PFS), potentially skipping a full feasibility study if current market conditions and U.S. supply concerns persist.
The PFS, released Tuesday, outlines an eight-year open-pit mining operation drawing from the Desert Scheelite and Garnet deposits, located approximately two kilometers apart. The pits would supply a 4,000-tonne-per-day processing mill, yielding an estimated 15,916 tonnes of tungsten trioxide (WO3) in concentrate over the mine's lifespan, along with 2.1 million ounces of silver.
Probable reserves are estimated at 11.8 million tonnes, grading 0.171% WO3, 9.28 grams of silver per tonne, and 0.28% zinc, translating to 20,275 tonnes of WO3, 3.5 million ounces of silver, and 33,396 tonnes of zinc. The project is situated approximately 270 kilometers southeast of Carson City, the state capital.
Pilot Mountain is one of the most advanced tungsten projects in the United States, a country that has not produced tungsten commercially since 2015, according to U.S. Geological Survey data. Guardian CEO Oliver noted that Washington is actively seeking domestic sources of tungsten to reduce reliance on China as its dominance over the global market deepens. The company plans to submit its mine plan to the Bureau of Land Management next month.
