Perpetua Resources Launches Antimony Processing Pilot Plant with US Army and Idaho National Laboratory
Perpetua Resources, in collaboration with the U.S. Army and Idaho National Laboratory (INL), has launched a modular mineral processing pilot plant to advance domestic antimony trisulfide production. The facility is designed to demonstrate an end-to-end supply chain for this critical mineral essential to national security applications such as defense munitions and battery technologies. The Stibnite Gold Project, located in central Idaho, contains the only identified reserve of antimony within the U.S., making it a key asset in reducing reliance on foreign sources. The plant will process samples from Perpetua's project into high-quality antimony trisulfide for specialized military and industrial use. This initiative is part of an ongoing multi-year collaboration between the Army, through the Defense Ordnance Technology Consortium (DOTC), and Perpetua to establish a fully domestic 'ground-to-round' supply chain. The pilot plant also aims to support future processing of other critical minerals.
