Strong economics, scalable growth: 3 Mtpa base case offers NPV10% of US$558M, IRR 24%, with a low-risk CAPEX of US$456M. Billion-dollar potential: 6 Mtpa case delivers NPV10% of US$1.17B, IRR 28.4%, and CAPEX of US$737M. First-mover advantage: State land tenure accelerates permitting, positioning ARR as a leading U.S.-based rare earths developer independent of tariffs and reliance on foreign processing. Vast Scalability [...]
Key Highlights Metallurgical test work confirms Halleck Creek ore can be upgraded by 10:1, validating a simple and effective early-stage beneficiation process. 93.5% of non-rare earth material can be removed early in processing, meaning only 6.5% of mined ore requires further refining, significantly reducing processing costs. This metallurgical milestone confirms the 10x upgrade assumption in the Scoping Study1 [...]
