Project Overview - Halleck Creek deposit has a JORC resource estimate of 2.63 billion tonnes with grades of 3,292 ppm TREO[18] - The project's 2025 Updated CSM Scoping Study showed a post-tax NPV10% of US$558 million and ~24% IRR[18] - Phase 1 is a 3 Mtpa separate and independent case that will mine ~62.3Mt of ore over 20 years, utilizing just ~2.4% of the 2.63 bn tonnes JORC resource[15] Cowboy State Mine (CSM) Production - CSM outlines a life of mine average annual production of 1,833 tonnes of NdPr Oxide, 98 tonnes of Dy Oxide and 24 tonnes of Tb Oxide[29] - The Cowboy State Mine resource only accounts for ~20% of the larger Halleck Creek deposit[37] - CSM accounts for ~20% of the overall Halleck Creek deposit[40] Financials and Economics - Scalable project with post-tax NPV10% of US$558 million, IRR of 24%, and a ~2.5-year payback period[14] - Competitive average LOM NdPr Eq cost of ~US$36 / kg[14] - Initial Capex is US$456 million[30, 39] Resource Base - Current JORC resource of 2.63 billion tonnes and grade of 3,292 ppm TREO[14] - Magnet elements account for ~26% of the total rare earth oxide ("TREO") content, with heavy rare earths accounting for ~11% of the TREO[32]
