Idaho National Laboratory Partners with Perpetua for Antimony Processing to Support U.S. Military Needs
Perpetua Resources has announced a partnership with the Idaho National Laboratory (INL) to develop a pilot processing plant for antimony, a mineral critical to national defense. The plant will refine antimony ore from Perpetua's Stibnite Gold Project in Valley County, Idaho, to military-grade specifications. This collaboration aims to address a national security need by providing a domestic source of antimony, which is currently not produced in the U.S. The Stibnite project is expected to produce nearly 150 million pounds of antimony over its operational life, with up to 10% of the ore designated for military use. The U.S. Department of War plans to use the refined antimony in various munitions and military applications. The project has received over $20 million in federal funding to develop the supply chain, and the pilot plant is scheduled to be built early next year.
