Perpetua Resources partners with Idaho National Laboratory in critical minerals

Perpetua Resources (PPTA) has entered an agreement with the Idaho National Laboratory, or INL, via Battelle Energy Alliance, for the INL to host, commission, and operate a flexible, modular pilot processing plant expected to be capable of recovering various critical and defense-related minerals, including antimony from the company’s ores. This initiative is intended to demonstrate the feasibility of producing high-quality, military specification antimony trisulfide using material from Perpetua’s Stibnite Gold Project. Locating the pilot plant at INL leverages the lab’s critical and strategic materials and defense programs. Once installed, the pilot plant will receive samples of material from the Stibnite Gold Project and operators will conduct pilot-scale testing to produce antimony trisulfide concentrate needed for munitions and advanced systems used by U.S. military personnel. The Stibnite Gold Project is the only identified reserve of antimony in America. The company expects to supply up to 35% of U.S. antimony demand during its first six years of operations while meeting long-term Department of War antimony needs.
