COPAUR FILES TECHNICAL REPORT FOR THE PRELIMINARY ECONOMIC ASSESSMENT FOR THE KINSLEY MOUNTAIN GOLD PROJECT

Copaur Minerals Inc. has filed on SEDAR+ the technical report for the preliminary economic assessment (PEA) for its 100-per-cent-owned Kinsley Mountain gold project in eastern Nevada, 80 kilometres south of West Wendover.

The full report can also be viewed on Copaur's website.

As previously reported: At a long-term consensus gold price of $4,000 (U.S.) per ounce gold, the project yields an after-tax net present value (discounted at 5 per cent) of $104-million (U.S.), an after-tax internal rate of return of 49 per cent and an after-tax payback period of 1.8 years. The PEA also reports a 52-per-cent 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 grams per tonne gold, which includes 384,000 indicated ounces at 5.32 grams per tonne gold 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, chief executive officer of Copaur Minerals.

Copaur retained Global Resource Engineering (GRE) and Apex Geoscience Ltd. 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.

ImpactDeck engagement: Further to the news release dated March 27, 2026, Copaur Minerals continues to engage the services of ImpactDeck, a leading investor relations firm led by James McFarland, based in Montreal, Que.

To further clarify, the contract is between Copaur Minerals (the issuer) and ImpactDeck (the service provider). The only relationship between Copaur Minerals and ImpactDeck and/or James McFarland is as per the terms of the agreement, nominally that Copaur will pay ImpactDeck a cash consideration of $5,000 per month, commencing April 1, 2026, for an initial six-month period, ending Oct. 1, 2026. There is an option to continue this services agreement on a month-to-month basis thereafter. There is no additional relationship between Copaur and ImpactDeck and/or Mr. McFarland.
