BOISE, ID – Perpetua Resources Corp. (Nasdaq: PPTA / TSX: PPTA) (“Perpetua Resources” or “Perpetua” or

About Perpetua Resources and the Stibnite Gold Project
Perpetua Resources Corp., 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 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 US-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 ad vance
construction readiness and permitting of the Project. Antimony trisulfide from Stibnite is the only known
domestic source of antimony that can meet U.S. defense needs for many small arms, munitions, and missile
types. In addition to the company’s com mitments to transparency, accountability, environmental
stewardship, safety and community engagement, Perpetua Resources adopted formal ESG commitments
which can be found here.
