American Rare Earths Is Betting That Scale Is the Easy Part
At Halleck Creek, Mark Wall’s priority is turning a vast Wyoming rare earth resource into a commercially viable American supply chain. In a recent conversation with Tracy Hughes, the Chief Executive Officer of American Rare Earths Limited (ASX: ARR | OTCQX: ARRNF) explained why growing the deposit is no longer the company’s immediate focus. That shift is the most interesting thing about American Rare Earths right now, and it frames both the opportunity and the risk.The headline numbers come from the updated Scoping Study for the Cowboy State Mine, the initial development phase of Halleck Creek in Wyoming. It estimates an after-tax net present value of approximately US$1.07 billion at an 8% real discount rate and an after-tax internal rate of return of 21%. Initial capital is estimated at approximately US$900 million, including contingency, and the model assumes an NdPr oxide price of US$151 per kilogram. These are preliminary project economics, with no ore reserves declared, rather than an established valuation of the company or a completed mine-to-magnet business.Wall’s gloss on the scale is the telling part. The initial mine plan “uses around 4% of the resource, which really just gives a sense of scale of this deposit.” The broader Halleck Creek mineral resource stands at approximately 2.63 billion tonnes, grading 3,292 parts per million total rare earth oxides. The distinction matters: the initial mine plan uses a small fraction of Halleck Creek, while the Cowboy State Mine resource itself represents a substantially larger share of the overall deposit.That is why the latest drilling focused on improving geological confidence and supporting development studies. Infill drilling can support future reserve estimation, but declaring reserves also requires the relevant technical and economic assessments. Wall described the mineralization as “porphyry-like”, contiguous and consistent, and said the campaign also tested theories about where grade runs a little higher. In a bulk, low-grade system, modest grade gains in the early years can matter disproportionately to payback. That detail deserves more attention than the drill metres.The harder question is whether the company can help carry the project from rock through to the magnet supply chain. Wall is explicit that this is the ambition. “This is a technology business,” he said. “We’re trying to get through to the end product, which is a magnet, which essentially enables technology to move.” The upstream, he concedes, is “a fairly simple mine.” The difficulty, and much of the potential value, lies downstream in processing, separation and metallization, where commercial execution remains to be demonstrated.The pilot program is therefore the thing to watch. At the time of the interview, Wall said material had been mined and crushed in Wyoming and that the concentration circuit was awaiting a final equipment item. The company’s published program envisages concentration work in Wyoming followed by hydrometallurgical processing at Saskatchewan Research Council, with separated rare earth oxide targeted for late Q2 2027. Wall says hydrometallurgical recoveries are already very good and identifies physical separation as the place “where we see real opportunity to improve further the economics of the project by increasing the recoveries.”To read the full column, go to: https://bit.ly/4dOSfsvDisclaimer: Video interviews and other video content published by InvestorNews are produced as part of paid media services.
