Full summary
American Rare Earths Limited (ASX: ARR) reported certified assay results from the first six HQ core drill holes of the 2026 Feasibility Study drilling program at the Cowboy State Mine, part of the Halleck Creek Rare Earths Project in Wyoming. The results confirm broad, near-surface rare earth mineralization with a mean pooled TREO grade of 3,497 ppm and a median grade of 3,879 ppm. Approximately 93% of the sampled intervals exceed the Company's 1,000 ppm TREO cut-off grade, supporting the robustness of near-surface mineralization. The highest single-sample assay returned 9,084 ppm TREO over a 3.02-meter interval. These results provide additional geological and analytical data to support ongoing Feasibility Study work at the Cowboy State Mine.
