American Rare Earths Launches WPDA for 8,108-Acre Halleck Creek District Expansion
American Rare Earths has awarded a whole-of-property development assessment (WPDA) for its 8,108-acre Halleck Creek project, integrating geologic, metallurgical and permitting data in a June 2026 study. The WPDA will outline multi-stage growth across Red Mountain, Overton Mountain and Bluegrass to support 5–10 Mtpa production and extend mine life.
1. WPDA Awarded for District-Scale Assessment
American Rare Earths has engaged a major engineering firm to conduct a whole-of-property development assessment across its 8,108-acre Halleck Creek landholding. The planning-level study, beginning in the June 2026 quarter, will integrate geological, metallurgical, mining and permitting data to shape a multi-stage expansion strategy.
2. Resource Scale and Development Phases
Halleck Creek hosts an in-situ resource of approximately 2.63 billion tonnes, with the Phase 1 Cowboy State Mine poised for a 20-year life under a low strip ratio. The WPDA will compare resource zones on grade, metallurgy and infrastructure access to sequence future phases and evaluate 5–10 Mtpa production scenarios.
3. Permitting Pathways and Policy Alignment
The study will map federal and state permitting pathways, including Bureau of Land Management ground, to support expansion beyond current footprints. This initiative aligns Halleck Creek with U.S. critical minerals policy, aiming to position the project as a cornerstone of domestic rare earth supply chain independence.
