Idaho Copper Corp. (NYSE American: COPR) has announced the results of an updated preliminary economic assessment (PEA) for its 100%-owned CuMo copper-molybdenum-silver project in Boise County, Idaho. The study, which was released via MiningNewsWire, outlines an after-tax net present value (NPV) of $1.88 billion at an 8% discount rate, an after-tax internal rate of return (IRR) of 18.5%, and a payback period of 5.9 years. The project has an estimated 46-year mine life, with initial capital costs of $1.17 billion and an additional $658 million in expansion capital planned for year five. These figures underscore the project's potential to become a significant long-term producer of critical minerals in the United States.
The updated PEA incorporates several key optimizations designed to reduce upfront capital requirements and accelerate payback. These include a smaller initial processing plant, X-ray fluorescence (XRF) sensor-based ore sorting, and a revised mine plan that accesses higher-grade material earlier in the mine life. Average annual production over the first 21 years is projected at 41.6 million pounds of copper, 30.5 million pounds of molybdenum, and 1.36 million ounces of silver. At spot metal prices as of October 12, 2026, the study estimates an after-tax NPV of $6.24 billion, an IRR of 38.4%, and a payback period of 3.4 years, highlighting the project's leverage to improving market conditions.
The importance of this announcement lies in its demonstration of a more capital-efficient development path for a project that is already considered one of the largest undeveloped copper deposits in the US. The CuMo project comprises approximately 2,640 acres and consists of 126 federal unpatented lode mining claims and 6 patented mining claims. It also contains significant amounts of silver, rhenium, and tungsten—all considered critical or of strategic importance. As the world transitions to cleaner energy technologies, demand for copper and other critical minerals is expected to rise, making projects like CuMo strategically vital for domestic supply chains.
Idaho Copper plans to advance pilot-scale testing to validate its ore-sorting assumptions and conduct the bulk of its prefeasibility study work in 2027, targeting completion in 2028. This next phase will be closely watched by investors and industry analysts.
