Perpetua to issue RFP re antimony processing

Mr. Jon Cherry reports PERPETUA RESOURCES UNVEILS NEXT STEPS TO SECURE COMMERCIAL DOWNSTREAM ANTIMONY PROCESSING Perpetua Resources Corp. has provided an update on the company's continuing 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 offtake arrangements for commercial-grade antimony. The company plans to issue a request for proposal (RFP) 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 record, creditworthiness, production readiness, transport reliability, and the ability to meet end-users' 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 under way between Perpetua and the U.S. Army to secure the domestic supply chain of mil-spec antimony trisulphide through the Defense Ordnance Technology Consortium (DOTC), for which the company has been awarded up to $22.4-million under an ordnance technology initiative agreement. "America needs a secure and robust supply of antimony," said Jon Cherry, president and chief executive officer of Perpetua Resources. "Work has been under way between the U.S. Army and Perpetua to advance downstream processing for defence needs, but it is now time we also respond to the needs of the U.S. manufacturing and industrial sectors. We are encouraged by emerging opportunities to expand domestic mineral processing capacity in America and intend to make well-informed, market-based decisions when selecting a partner." 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. About Perpetua Resources Corp.
