Starting with a smaller plant and sorting the ore before it reaches the mill means we need materially less capital up front, with a rapid payback driven by ore sorting. Very few copper projects anywhere combine returns at this level with such a strong mine life, and fewer still sit in the United States and carry molybdenum, rhenium and tungsten alongside the copper.\u201d<\/p>\n<p align=\"justify\">\u201cAt spot metals prices (12 October 2026): with $6.76\/lb. copper, $42.05\/lb. molybdenum, and $60.56\/oz. silver&#8211;after-tax NPV rises to US$6.24 billion, IRR to 38.4% and payback reduces to 3.4 years.\u201d<\/p>\n<p align=\"justify\">\u201dMolybdenum also drives our cost position \u2013 credits from molybdenum more than cover the cost of producing copper \u2013 and we believe our diversified metal production gives CuMo one of the most competitive cost positions on a by-product basis, with substantial copper and silver revenues providing a significant advantage over comparable projects. Our focus now is the Prefeasibility Study, with the bulk of that work to be conducted in 2027 and completion targeted for 2028, along with the pilot-scale test work that will validate our ore-sorting assumptions at commercial scale,\u201d concluded Brodkey.<\/p>\n<p>\n        <b>Full Study Details<\/b>\n      <\/p>\n<p align=\"justify\">A summary of the updated PEA and technical report, including the mineral resource estimate, the mine and processing plan, capital and operating cost detail and full sensitivity analysis, will be filed on Form 8-K with the SEC, and a corresponding NI 43-101 technical report will be filed on SEDAR+.

The CuMo project is one of the largest undeveloped copper deposits in the US, and the Company believes it is among the largest undeveloped molybdenum deposits in the world. CuMo contains significant amounts of silver, rhenium, and tungsten \u2013 all considered critical or of strategic importance. The project comprises approximately 2,640 acres and consists of 126 federal unpatented lode mining claims and 6 patented mining claims.

C1 costs are reported per payable pound of copper or molybdenum, after deducting net revenues from the other metals as by-product credits. C1 includes site operating and property-holding costs and the selling costs attributable to the primary metal. AISC adds sustaining capital and the royalties and corporate overhead included in the model. Costs are calculated over the life of mine and exclude initial and expansion capital. Copper-equivalent figures use the metal prices and recoveries set out in the technical report. These measures have no standardized meaning under U.S. GAAP and may not be comparable to similar measures presented by other companies.<\/p>\n<p>\n        <b>Cautionary Statement Regarding the PEA<\/b>\n      <\/p>\n<p align=\"justify\">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 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.<\/p>\n<p>\n        <b>Safe Harbor Statement<\/b>\n      <\/p>\n<p align=\"justify\">With the exception of historical information contained in this press release, content herein may contain \u201cforward-looking statements\u201d that are made pursuant to the Safe Harbor Provisions of the U.S. Private Securities Litigation Reform Act of 1995.

(NYSE American: COPR) (\u201cIdaho Copper\u201d or the \u201cCompany\u201d) today announced the results of an updated Preliminary Economic Assessment (\u201cPEA\u201d) for its 100%-owned CuMo copper-molybdenum-silver project in Boise County, Idaho. The study was prepared and is being finalized under the direction of Barr Engineering Co. and other qualified persons, and will supersede the Project\u2019s 2020 PEA. The updated PEA will reflect a smaller first-phase plant, XRF sensor-based ore sorting ahead of the mill, and a re-sequenced mine plan that reaches higher-grade ore sooner.
