Management Commentary

Andrew Brodkey, Chief Executive Officer of Idaho Copper, commented, “Our updated Preliminary Economic Assessment describes a very different CuMo project from the one contemplated in 2020. A smaller first-phase plant and sensor-based ore sorting ahead of the mill materially lower the capital needed to begin production and accelerate payback, while CuMo’s molybdenum, silver, rhenium and tungsten add diversification few U.S. copper projects can match.

“With U.S. Forest Service approval to commence drilling now in hand, our focus is the Prefeasibility Study, with completion targeted for 2028, along with the pilot-scale test work that will validate our ore-sorting assumptions at commercial scale. We look forward to walking investors through the PEA results and the milestones ahead,” concluded Mr. Brodkey.

Qualified Person

The scientific and technical information in this news release has been reviewed and approved by Justin Smith, P.E., of Northern Lights Mining, LLC., a “qualified person” as defined under Regulation S-K 1300 and National Instrument 43-101, and independent of the Company.

Cautionary Statement Regarding the PEA

The PEA is preliminary in nature and includes an economic analysis based, in part, on inferred mineral resources. Inferred mineral resources are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the results of the PEA will be realized. Mineral resources are not mineral reserves and do not have demonstrated economic viability. No mineral reserves have been estimated for the Project. The PEA is not a prefeasibility or feasibility study, and the Company has not made a decision to construct the CuMo project. The updated PEA has been prepared in accordance with both NI 43-101, and is currently being prepared in accordance with Regulation S-K 1300; the requirements of these standards are similar in many respects but are not identical, and estimates prepared under one may not be directly comparable to estimates prepared under the other.
