By addressing the growing demand for rare earth elements in defense, renewable energy, and advanced technologies, the company is poised to play a transformative role in the global economy.
American Rare Earths (ARRNF) has announced results from its Updated Halleck Creek Scoping Study, revealing strong economic potential for its rare earths project in Wyoming. The study presents two development scenarios:
The 3 Mtpa base case shows:
- NPV10% of US$558M with 24% IRR
- CAPEX of US$456M with 2.7-year payback
- Annual production of 4,169 metric tons TREO, including 1,833 tons NdPr oxide
The 6 Mtpa case demonstrates:
- NPV10% of US$1.17B with 28.4% IRR
- CAPEX of US$737M with 1.8-year payback
- Annual production of 7,661 metric tons TREO, including 3,344 tons NdPr oxide
The project benefits from state land tenure for accelerated permitting and covers only 16% of the total project area, with significant expansion potential. First production could begin by 2029.
American Rare Earths (ARRNF) has achieved a significant metallurgical milestone at its Halleck Creek Rare Earths Project in Wyoming. Large-scale testing has successfully demonstrated a 10:1 upgrade in rare earth concentration, increasing from 3,438 ppm (0.34%) TREO to 37,200 ppm (3.72%) TREO using conventional, low-cost methods.
The test work, conducted with Mineral Technologies on a 1.9-tonne sample, utilized MG12 Spirals and Induced Roll Magnetic Separation (IRMS) technology. The process effectively removes 93.5% of non-rare earth material early in processing, meaning only 6.5% of mined ore requires further refining, potentially reducing operating costs significantly.
The initial TREO recovery rate was 62%, below the 78% outlined in the Scoping Study. However, optimization work is ongoing to enhance recoveries while maintaining the 10X upgrade factor. These results validate key assumptions in the Scoping Study and will support the upcoming Pre-Feasibility Study (PFS).
American Rare Earths (ARRNF) announced a significant update to its Halleck Creek Rare Earth Project in Wyoming. The total mineral resource estimate increased by 12.2% to 2.63 billion tonnes at 3,926 ppm Total Rare Earth Oxides (TREO). The Red Mountain Area saw a 29.7% growth in resources to 1.24 billion tonnes, with an 8.3% grade increase to 3,252 ppm TREO.
The Cowboy State Mine, representing the first phase of development, expanded by 29.4% to 543 million tonnes, with a 2.7% increase in TREO grade to 3,438 ppm. The deposit remains open at depth and along strike, with the current estimate covering only 16% of the project area. The company plans to release an updated Scoping Study in February 2025, followed by a Pre-Feasibility Study later in the year.
American Rare Earths (ARRNF) has been recognized in the 2025 OTCQX® Best 50, ranking as the third most traded company among top performers on the OTCQX Best Market in 2024. The ranking is based on one-year total return and average daily dollar volume growth during the previous calendar year.
The company's Halleck Creek Project, containing 2.34 billion tonnes of TREO under JORC standards, is positioned as a key component of the U.S. rare earths supply chain. The project aims to reduce American dependence on foreign imports while supporting clean energy and defense technologies.
The OTCQX Best Market recognition highlights companies meeting high financial standards, following best practice corporate governance, and maintaining securities law compliance.
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.
