Idaho Copper Corp. (NYSE American: COPR) has released an updated preliminary economic assessment (PEA) for its 100%-owned CuMo copper-molybdenum-silver project in Boise County, Idaho, revealing an after-tax net present value (NPV) of $1.88 billion at an 8% discount rate. The study also projects an after-tax internal rate of return (IRR) of 18.5% and a payback period of 5.9 years, with an estimated 46-year mine life. Initial capital costs are set at $1.17 billion, with an additional $658 million in expansion capital planned for year five. Over the first 21 years, average annual production is forecast at 41.6 million pounds of copper, 30.5 million pounds of molybdenum, and 1.36 million ounces of silver.
The updated PEA incorporates a smaller initial processing plant, X-ray fluorescence (XRF) sensor-based ore sorting, and a revised mine plan designed to access higher-grade material earlier, reducing upfront capital requirements and accelerating payback. This strategic shift could enhance the project's economic resilience amid volatile metal markets. 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 significant upside potential.
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.

The company's progress is closely watched, as reflected in market data accessible via Idaho Copper (NYSE American: COPR).
The CuMo project is one of the largest undeveloped copper deposits in the United States and is believed to be among the largest undeveloped molybdenum deposits globally. It also contains significant amounts of silver, rhenium, and tungsten—all critical or strategically important minerals. Comprising approximately 2,640 acres, the project includes 126 federal unpatented lode mining claims and 6 patented mining claims. More information is available at www.idaho-copper.com.
The announcement is significant for U.S. critical minerals security, as domestic sources of copper and molybdenum reduce reliance on foreign supply chains. Copper is essential for electrification, renewable energy, and infrastructure, while molybdenum is vital for steel alloys and defense applications. With a 46-year mine life and robust economics, CuMo could become a cornerstone of American mineral independence. The updated PEA's focus on reducing capital intensity and accelerating payback positions the project favorably for potential financing and development.
