Perpetua Resources Corp.: Pioneering Antimony Supply Chain Security in a Decarbonizing World

In an era where decarbonization and geopolitical stability are inextricably linked, critical minerals like antimony have emerged as linchpins for both clean energy transitions and national security. Perpetua Resources Corp. (PPTA) is at the forefront of securing a domestic antimony supply chain, a strategic move that aligns with global efforts to reduce reliance on foreign sources and bolster industrial resilience. As the only U.S. antimony reserve, the company's Stibnite Gold Project in Idaho is not just a mining operation—it is a catalyst for redefining supply chain dynamics in a world increasingly defined by energy innovation and geopolitical risk.

Strategic Downstream Processing: Bridging the Gap

Perpetua's recent Request for Proposal (RFP) to evaluate off-site processing partners underscores its commitment to closing the U.S. antimony supply chain's most critical gap: refining capabilities.
