On July 9, 2026, Hunter Diamond, CFA of Diamond Equity Research initiated coverage with an illustrative valuation of US$22.75 per share on Idaho Copper Corp. (COPR:NYSEAMERICAN), implying roughly 491% upside from the July 9, 2026 price of US$3.85, following the company's NYSE American uplisting and public offering and ahead of an updated preliminary economic assessment (PEA) that management expects will materially reduce initial capital intensity at its CuMo Project.

Company and Project Overview

Idaho Copper is a pre-revenue, single-asset mineral development company advancing the CuMo Project, a copper–molybdenum–silver deposit with rhenium and tungsten credits located in Boise County, Idaho, approximately 37 miles from Boise. The project comprises 126 unpatented and six patented mining claims covering roughly 2,640 acres within the Boise National Forest, and is held through wholly owned subsidiary International CuMo Mining Corporation following a January 2023 share exchange in which ICUMO shareholders received approximately 90.1% of outstanding shares. The report describes CuMo as "one of the largest undeveloped copper deposits in the US and... potentially the largest undeveloped molybdenum deposit globally."

Resource Base

At a US$5.00 per ton recoverable metal value cut-off, the 2020 PEA reported measured and indicated resources of approximately 2.27 billion short tons grading 0.084% copper, 0.057% MoS₂, 2.50 g/t silver, and 0.021 ppm rhenium, alongside inferred resources of approximately 2.56 billion short tons. Grades are low and typical of bulk-tonnage porphyry systems, where economics depend on scale and throughput efficiency. Drilling has not covered the full interpreted mineralized system, which is estimated to extend up to approximately 4.5 km in diameter, though no drilling has been conducted since 2012, introducing uncertainty around current resource confidence.

Ore Sorting as the Central Value Catalyst

The 2020 PEA prepared by SRK Consulting (Canada) Inc. outlined a 150,000 tons-per-day open-pit operation with an approximately 30-year mine life, initial capital expenditure of roughly US$3.1 billion, life-of-mine revenue of about US$29.1 billion, an after-tax NPV (8%) of US$356 million, and an after-tax IRR of 9%. That study assumed ore sorting would reject approximately 28% of mining waste ahead of the concentrator. Subsequent work, including 2024 MineSense XRF scanning testwork and visual scanning of historical drill core, indicated that up to 84% of waste and lower-grade material could theoretically be separated from higher-grade material. Diamond Equity Research cautions that this "is not yet the same as a bankable metallurgical outcome, but it is a major potential upside lever." The updated PEA, led by Barr Engineering with optimization support from Whittle Consulting and expected in mid-2026, is anticipated to shift the design to a 25,000–30,000 tonnes-per-day configuration with initial capex targeted at approximately US$1.2 billion.

Permitting and Litigation

The U.S. Forest Service issued the Final Environmental Assessment, Record of Decision, and Finding of No Significant Impact on March 14, 2025, along with a Decision Notice approving the company's Exploration Plan of Operations, permitting seasonal exploration between April 15 and December 15 annually over a four-year period beginning in 2025. Non-governmental organizations filed a legal challenge in June 2025 in the Federal District Court of Idaho opposing the exploration drilling program, though no preliminary injunction had been filed to halt 2026 drilling. The analyst views exploration permitting as "seemingly de-risked from an approval standpoint," with residual risk centered on litigation-driven delays rather than revocation of granted permits.

Financial Position

For the fiscal year ended January 2026, total operating expenses were approximately US$2.6 million against US$4.7 million in the prior year, with roughly 55% attributable to stock-based compensation. Net loss narrowed to approximately US$3.07 million from US$5.14 million, and operating cash burn was approximately US$0.82 million. For the three months ended April 30, 2026, operating expenses rose to approximately US$1.34 million from US$0.56 million, driving a net loss of approximately US$1.51 million versus US$0.68 million a year earlier. Cash stood at US$164.21 thousand as of April 2026, excluding offering proceeds. The company completed its NYSE American uplisting and a public offering of 3.71 million shares and 3.71 million accompanying warrants at a combined price of US$4.85 per unit, generating estimated net proceeds of approximately US$16 million; the warrants trade as COPR WS and are exercisable at US$5.75. Shares outstanding total 18.47 million for a market capitalization of approximately US$71.11 million. Near-term advancement requires approximately US$40 million to fund the PFS, targeted for completion by the end of 2027, including roughly US$12 million of drilling and about US$1 million of metallurgical studies.

Commodity and Policy Backdrop

Global copper demand is projected to rise from approximately 28 million tonnes to around 42 million tonnes by 2040, against a potential shortfall of roughly 10 million tonnes, equivalent to about 25% of projected demand. LME copper traded in the range of approximately US$13,000–13,300 per tonne (~US$6.00 per pound) in April 2026 after reaching highs above US$14,500 per tonne earlier in the year. U.S. import reliance for refined copper increased from approximately 37% in 2019 to about 45% in 2024 and is expected 57% in 2025. Policy frameworks, including the Inflation Reduction Act, the Bipartisan Infrastructure Law, FAST-41, and the Defense Production Act, alongside Department of Energy and Department of War funding mechanisms covering up to 50% of eligible study and development costs, could support the project, though grant awards remain competitive and are treated as potential upside rather than a core funding assumption. 

Valuation Methodology

The bottom-up model assumes 1.582 billion short tons of LOM mill feed over 28 years, generating LOM revenue of approximately US$47.39 billion, comprising US$31.62 billion from molybdenum, US$12.05 billion from copper, and US$3.73 billion from silver, based on long-term prices of US$25 per pound molybdenum, US$5.00 per pound copper, and US$45 per ounce silver. Initial capex of US$1.2 billion, LOM sustaining capex of US$972 million, and closure costs of US$150 million are assumed, with COGS and G&A modeled at US$9.00 and US$0.50 per ton of mill feed. Discounting at 10.0% with no terminal value and applying a 15% probability of success yields a risk-adjusted equity value of US$414.11 million. A GPCM price-to-mine-plan-tonnage approach, benchmarked against peers, yields US$437.38 million. Weighted 75% to DCF and 25% to GPCM, the blended equity value of US$419.93 million across 18,469,326 shares produces the US$22.75 per share figure.

Risks

Key risks identified include single-asset concentration, funding and capital intensity given capital expenditures exceeding US$1 billion with no committed financing for the PFS or BFS, pre-revenue development stage risk, permitting and regulatory dependency under NEPA, resource estimation and geological uncertainty, reliance on external technical consultants, development and execution complexity, ongoing litigation and stakeholder opposition, and force majeure affecting a Mining Claims Agreement that currently constrains full title consolidation.

Outlook

The analyst frames progression along the development curve, from the updated PEA to the PFS and ultimately construction, as the principal value driver, with each milestone improving technical confidence and financing visibility. The US$22.75 valuation is explicitly "contingent on continued project de-risking, financing access, and successful execution." Diamond Equity Research LLC discloses that it is compensated by Idaho Copper Corporation for producing research materials, having been paid US$50,000 for company-sponsored research services commencing April 16, 2026.
