American Rare Earths Accelerates Wyoming Pilot Plant for Rare Earth Oxide Production
Event summary
- American Rare Earths (ARR) has defined a pilot plant pathway for its Halleck Creek Project in Wyoming, with initial processing in Wyoming and final refining in Canada.
- The pilot plant program is structured in three stages: milling and sizing, mineral separation and concentration, and leaching, impurity removal, and oxide refining.
- ARR has executed agreements with Western Research Institute, DISA Technologies, and Saskatchewan Research Council for mineral processing activities.
- The Company expects to materially shorten the timeline to produce pre-production rare earth oxide and validate the broader process flowsheet.
- Jaye T. Pickarts, P.E., a metallurgical engineer with over four decades of experience, will lead the pilot plant process.
The big picture
American Rare Earths' accelerated pilot plant pathway for the Halleck Creek Project is a strategic move to reduce U.S. reliance on imported rare earth elements, predominantly from China. By combining Wyoming-based front-end processing with proven downstream refining infrastructure, ARR aims to validate its process flowsheet and generate material for strategic engagement. This initiative aligns with broader industry trends towards securing critical mineral independence and meeting the growing demand for rare earth elements essential to defense and advanced technologies.
