Idaho Copper Announces Results of Updated Preliminary Economic Assessment for the CuMo Project: After-Tax NPV of US$1.88 billion, 18.5% IRR and a 46-Year Mine Life
Idaho Copper's updated PEA for its 100%-owned CuMo project shows an after-tax NPV of US$1.88 billion and 18.5% IRR, with a 46-year mine life and 5.9-year payback. The revised plan uses a smaller first-phase plant, XRF ore sorting and a re-sequenced mine plan, cutting initial capital to US$1.17 billion and pushing higher-grade ore earlier. At October 2026 spot prices the after-tax NPV rises to US$6.24 billion with a 38.4% IRR; molybdenum by-product credits drive negative copper C1 costs of -$4.30/lb.
