Perpetua Resources updates efforts to secure American antimony supply chain

Perpetua Resources (PPTA) provided an update on the company’s ongoing efforts to help secure the American antimony supply chain. The Stibnite Gold Project is the only domestic reserve of antimony in the United States and with the conditional Notice to Proceed from the U.S. Forest Service in hand, the Company is ready to enter into long-term off-take arrangements for commercial grade antimony. The Company plans to issue a Request for Proposal to assess the technical and economic feasibility of multiple emerging potential off-site processing facilities from third parties to secure antimony for domestic uses. The RFP review process will evaluate companies on potential production capacity, capitalization, reliability, environmental track record, credit worthiness, production readiness, transport reliability, and the ability to meet end user’s product requirements and market needs, among other factors. The RFP process will evaluate processing suitability for the portion of Perpetua’s 148-million-pound antimony reserve designated for commercial purposes and is separate from the work currently underway between Perpetua and the U.S. Army to secure the domestic supply chain of mil-spec antimony trisulfide through the Defense Ordinance Technology Consortium for which the company has been awarded up to $22.4M under an Ordnance Technology Initiative Agreement. To date, the company has engaged in discussions with numerous parties including, but not limited to, Clarios, Glencore, Nyrstar, Sunshine Silver and Trafigura. The company is pursuing processing arrangements that maximize value for shareholders while securing an antimony supply chain for U.S. consumers. The company intends to issue the RFP in the coming weeks and make a final selection in the fourth quarter of 2025, subject to due diligence review.
