Perpetua Resources (Nasdaq: PPTA / TSX: PPTA), the U.S. Army and Idaho National Laboratory (INL), announced Thursday the opening of a new modular mineral processing plant designed to help establish an end-to-end domestic supply chain for antimony. Antimony is designated as a critical mineral essential to U.S. national and economic security. The pilot plant is the culmination of a multi-year collaboration between the U.S. Army via the Defense Ordnance Technology Consortium and Perpetua to advance a fully domestic, “ground-to-round” antimony supply chain. The U.S. Department of War and Perpetua Resources entered into a strategic effort focused on advancing domestic antimony trisulfide production. “Together, these investments are laying the foundation for a secure, end-to-end domestic supply chain that strengthens national security while creating long-term economic opportunity.”
