Perpetua Resources, through its wholly-owned subsidiaries, is focused on the exploration, site restoration, and redevelopment of gold-antimony-silver deposits in the Stibnite-Yellow Pine district of central Idaho that are encompassed by the Stibnite Gold Project. The Project is one of the highest-grade, open-pit gold deposits in the United States and is designed to apply a modern, responsible mining approach to restore an abandoned mine site and produce both gold and the only mined source of antimony in the United States. Antimony is a federally designated critical mineral for its use in the national defense, aerospace, and technology sectors. In addition to the company’s commitments to transparency, accountability, environmental stewardship, safety, and community engagement, Perpetua Resources adopted formal ESG commitments which can be found here.
