Sheep Creek Rare Earth Exploration Proposal

The Bitterroot National Forest received a draft initial plan of operations for the Sheep Creek Project from US Critical Materials on December 5, 2025. The company recently rescinded its proposal and anticipates submitting a revised proposal by the end of April. The Forest will then conduct a completeness review to determine if the proposal is sufficient to conduct environmental analysis. Once a new proposal is received, the project timeline will be updated on the FAST-41 Transparency webpage. To learn more about the project click here.
