Recent core samples from the Yellow Pine and Hangar Flats deposits show significant mineralization, including an intercept of 21.3 meters grading 3.2 g/t gold and 0.9% tungsten at the Clark Tunnel Fault Zone. At Hangar Flats, specialized drilling for critical minerals returned results as high as 8.3% antimony and 4.6% tungsten. These findings build on the district’s history; the Stibnite region served as a primary source of U.S. tungsten during the Second World War and the Korean War.

Perpetua CEO Jon Cherry stated that the company is focusing on high-grade targets to potentially extend the life of the permitted Stibnite Gold Project beyond its initial four-year plan. With four drill rigs currently active, the company has completed 5,800 meters of a planned 10,000-meter program. While the current mining permit is centered on gold and antimony, the discovery of tungsten has led management to submit a proposal for U.S. government grant funding to accelerate metallurgical analysis and resource evaluation. Any development of these new targets remains subject to separate environmental reviews and regulatory approval.
