American Rare Earths' Mark Wall on Wyoming’s Halleck Creek, America's Largest Rare Earths Deposit

When investors discuss the future of rare earths in North America, the conversation often gravitates toward processing plants, magnet manufacturing, and the geopolitical imperative of reducing Western dependence on China. Yet before any of that can happen, one question must be answered: where will the raw materials come from?According to Mark Wall, President and CEO of American Rare Earths Limited (ASX: ARR | OTCQX: ARRNF | ADR: AMRRY), one answer may lie in Wyoming.During a recent InvestorTalk interview, Wall described the Company’s Halleck Creek project as the largest rare earth deposit in the United States measured by total rare earth oxide (TREO) content — a distinction that has attracted increasing attention from investors, industry participants, and government stakeholders focused on rebuilding domestic supply chains.“Halleck Creek is the largest rare earth deposit in the domestic United States by far,” Wall told InvestorNews. “The first 25 years are on state land, and the next several hundred years are on federal land. It’s a really exciting deposit.”What distinguishes Halleck Creek from many other North American rare earth projects is not simply its size. Approximately one-quarter of the deposit consists of heavy rare earth elements, a category of materials that remains particularly scarce outside China.Heavy rare earths such as dysprosium and terbium play critical roles in advanced defense systems, aerospace applications, and high-performance permanent magnets. These materials are increasingly viewed as strategic assets by governments seeking secure domestic supply chains.“Heavy rare earths are really strategic,” Wall explained. “They’re used a lot in space applications, high altitude applications, and defense. They’re not common in the domestic United States, so it’s great having those.”The project also contains significant quantities of neodymium and praseodymium (NdPr), the magnet rare earths that underpin electric vehicles, robotics, advanced manufacturing, and countless clean-energy technologies.The timing could prove significant.Rare earths have emerged as one of the most important critical mineral sectors in North America as governments attempt to establish mine-to-magnet supply chains independent of Chinese control. While many projects remain years away from development, American Rare Earths is attempting to accelerate its timeline by advancing multiple workstreams simultaneously.Wall confirmed that the Company remains on track to complete its pre-feasibility study during the third quarter of 2026. However, management has already initiated feasibility-level work before publication of the pre-feasibility study in an effort to compress development timelines.“We’ve started the feasibility study before the PFS has been published,” Wall said. “We’re really compressing this work and doing a lot of things at the same time.”The strategy reflects growing urgency within the United States to establish domestic rare earth production capacity.“We need magnet rare earths,” Wall said. “We’re working at full speed.”Another potential catalyst for investors is the Company’s planned NASDAQ listing. Wall indicated that the process continues to advance and suggested a September-to-October timeframe remains a reasonable expectation.A successful NASDAQ listing would significantly increase the Company’s visibility among U.S. institutional investors at a time when critical minerals are becoming an increasingly important investment theme.Perhaps equally important is where the project is located.Wyoming has quietly emerged as one of the most attractive mining jurisdictions in North America, combining abundant infrastructure with a mature regulatory framework and a long history of resource development.To read the full column, go to: https://bit.ly/4vqnBfg
