About Perpetua Resources Corp. and the Stibnite gold project

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. Further advancing Perpetua Resources' ESG (environmental, social and governance) and sustainable mining goals, the project will be powered by the lowest carbon emissions grid in the nation and a portion of the antimony produced from the project will be supplied to Ambri, a U.S.-based company commercializing a low-cost liquid metal battery essential for the low-carbon energy transition. Perpetua Resources has been awarded a technology investment agreement of up to $24.8-million in Defense Production Act Title III funding to advance construction readiness and permitting of the project. Antimony trisulphide from Stibnite is the only known domestic source of antimony that can meet U.S. defence needs for many small arms, munitions and missile types. In addition to the company's commitments to transparency, accountability, environmental stewardship, safety and community engagement, Perpetua Resources adopted formal ESG commitments.
