Vancouver, British Columbia--(Newsfile Corp. - July 14, 2026) - CopAur Minerals Inc. (TSXV: CPAU) (the " Company " or " CopAur ") is pleased to announce that the Technical Report for the Preliminary Economic Assessment (the " PEA ") for its 100%-owned Kinsley Mountain Gold Project (the " Kinsley Mountain Gold Project ", " Kinsley " or the " Project ") in eastern Nevada, 80 km south of West Wendover, has been filed on SEDAR+ . The full report can also be viewed on CopAur's website: CopAur_KinsleyMountainGoldProject_PreliminaryEconomicAssessment As previously reported: CopAur Delivers Preliminary Economic Assessment and a 52% Mineral Resource Estimate Growth for the Kinsley Mountain Gold Project - CopAur Minerals Inc. At a long-term Consensus Gold Price of US$4,000/oz Au, the Project yields a post-tax NPV (5%) of US$104 million, a post-tax IRR of 49%, and a post-tax payback period of 1.8 years. The PEA also reports a 52% growth over the previous Mineral Resource Estimate ("MRE") to 742,000 Indicated ounces at 1.11 grams-per-tonne gold and 69,000 Inferred ounces at 1.98 g/t Au, which includes 384,000 Indicated ounces at 5.32 g/t Au within the high-grade Secret Canyon zone.

"The PEA demonstrates the compelling economic potential for a restart of Kinsley, and we look forward to continuing our permitting efforts based on the findings of the PEA. The updated MRE and geological model will further define future drill programs to quantify the near-surface oxide mineralization that remains open to the north of the existing open pit which will provide opportunities to significantly extend the overall mine life through future exploration success," commented Andrew Neale. CopAur retained Global Resource Engineering (" GRE ") and APEX Geoscience Ltd. (" APEX ") to complete the PEA and prepare the technical report in compliance with the guidelines of National Instrument 43-101 Standards of Disclosure for Mineral Projects (" NI 43-101 ").
