Perpetua Resources Secures $22.4M Pilot Plant to Supply 35% U.S. Antimony Demand
Perpetua Resources secured $22.4 million to build a modular pilot processing plant with Idaho National Laboratory under a Defense Ordnance Technology Consortium partnership. The facility will produce antimony trisulfide concentrate from the Stibnite Gold Project, targeting up to 35% of U.S. antimony demand in its first six years.
1. Strategic Partnership Details
Perpetua Resources entered into a collaboration with Idaho National Laboratory and the U.S. Army’s Defense Ordnance Technology Consortium to host, commission and operate a flexible, modular pilot processing plant aimed at critical mineral recovery.
2. Funding and Program Scope
The initiative received $22.4 million in consortium awards to design and deploy a scalable processing facility capable of recovering antimony and other defense-related minerals from the Stibnite Gold Project in Idaho.
3. Implications for U.S. Antimony Supply
By producing antimony trisulfide concentrate, the pilot plant is positioned to supply up to 35% of U.S. antimony demand over its first six years, strengthening domestic defense supply chains and reducing reliance on foreign sources.
