American Rare Earths (ARRNF) has announced that its subsidiary Wyoming Rare (USA) has been granted a License to Explore by Dozing at the Halleck Creek Rare Earths Project in Wyoming. The license enables test mining, trenching, and exploratory excavation, including bulk material sample collection at the Cowboy State Mine project area.
The bulk sampling authorization represents a important step for the company, as it will provide feedstock for future pilot plant testing at their recently acquired Laramie facility. This development will enable ARR to refine processing techniques and optimize project design, advancing toward commercial development.
CEO Chris Gibbs emphasized that this approval demonstrates their strong relationship with Wyoming state authorities and marks a significant step in developing the project while maintaining high environmental and community standards. The company will continue pilot plant testing, metallurgical analysis, and process optimization as part of their development strategy.
American Rare Earths (ARRNF) has announced that its subsidiary, Wyoming Rare (USA), has secured a facility at the Western Research Institute in Laramie, Wyoming. This development follows a recent $7.1 million grant from the State of Wyoming for rare earth processing initiatives.
The facility will serve multiple purposes, including housing drill core and assay samples, and accommodating the construction of a pilot plant for processing capabilities. The Western Research Institute, a not-for-profit research organization, specializes in advanced energy systems, environmental technologies, and materials research.
This strategic partnership aims to advance the Halleck Creek Rare Earths Project and strengthen Wyoming's position in critical minerals development while supporting the company's mission to onshore critical mineral supply chains for the USA.
American Rare Earths (ARRNF) has announced final assay results from its 2024 drilling campaign at the Cowboy State Mine area within the Halleck Creek Project, Wyoming. The results revealed the highest-grade Total Rare Earth Oxide (TREO) intersections recorded at the site, with significant intervals including: 148.0m @ 4,451 ppm TREO, 161.5m @ 4,275 ppm TREO, and 90.0m @ 4,353 ppm TREO. Multiple high-grade intersections exceeded 5,000 ppm TREO. The company plans to complete an updated resource estimate and Pre-Feasibility Study (PFS) for Halleck Creek in 2025.
American Rare Earths (ARRNF) has engaged BMO Capital Markets as its financial adviser to accelerate the development of the Halleck Creek Project in Wyoming.
