1. Updated project assessment
Idaho Copper’s updated preliminary economic assessment estimates an after-tax NPV of US$1.88 billion for its CuMo project in Idaho, with an 18.5% internal rate of return and a 46-year mine life. A smaller first-phase plant using sensor-based ore sorting lowers initial capital requirements and accelerates payback compared with the 2020 plan. U.S. Forest Service approval allows drilling to begin, and the company is targeting completion of a prefeasibility study for 2028.
