COPPER ONE RESOURCES COMPLETES SECOND DIAMOND DRILL HOLE AT REDHILL COPPER-ZINC VMS PROJECT, BRITISH COLUMBIA

Copper One Resources Corp. has successfully completed drilling its second diamond drill hole at its Redhill copper-zinc project, located south of Ashcroft, B.C., within the Kamloops mining district. Assay results will be released once received, compiled and interpreted.

The hole was drilled to a depth of 300 metres and is intended to test coincident electromagnetic, magnetic and geological targets interpreted to represent prospective volcanogenic massive sulphide (VMS) mineralization. The hole will also evaluate the continuity of mineralization intersected in historical drilling and further test the geological model developed from previous exploration.

The phase 1 drill program is designed to test priority VMS targets and follow up on extensive historical drilling and geophysical work that identified copper-zinc and gold/silver mineralization, hydrothermal alteration, and prospective sulphide-bearing volcanic units across the property. The initial program is expected to consist of approximately 3,000 metres of diamond drilling across 10 drill holes.

Drilling continues at Redhill with additional phase 1 holes planned over priority VMS targets. Analytical results from completed drill holes will be released once received, validated and interpreted.

David Greenway, chief executive officer of Copper One, commented: "Completion of our second drill hole marks another important milestone as we systematically evaluate the Redhill Project's VMS potential. Historical drilling, favourable geology and multiple coincident geophysical targets continue to reinforce our confidence in the property. We look forward to completing the remainder of the phase 1 program as we work to unlock additional copper and zinc discoveries in one of British Columbia's established mining districts."

As previously announced, to execute the program, Copper One engaged Paradigm Drilling Ltd., which will deploy a Boyles B-15 hydraulic, track-mounted diamond drill equipped with NQ tooling and capable of testing targets to depths exceeding 600 metres. Initial drill pads have been permitted and are currently being prepared, with stepout drilling planned to evaluate the continuity of VMS-style copper-zinc mineralization along prioritized structural and geophysical trends.

About the Redhill property

The Redhill property is located south of Ashcroft, B.C., within the Kamloops mining district, and is accessible through the Trans-Canada Highway. The property comprises 18 mineral claims totalling approximately 4,736.38 hectares (11,703 acres) and represents a large contiguous land package in a well-established mining region.

The property hosts VMS mineralization. Historical exploration, including work by Teck Resources Ltd. and others, identified multiple stratabound zones of hydrothermal alteration and copper mineralization. Mineralization occurs within sericite-altered felsic volcanic rocks and includes sulphide assemblages consisting of pyrite, pyrrhotite, and chalcopyrite in stringer and semi-massive sulphide to massive sulphide zones.

The area is correlated with the Kutcho terrane of Northern British Columbia, which hosts the large Kutcho VMS deposit.

Drilling conducted by Bessor Minerals Inc. in 2022 reported drill intercepts of:

• 6.9 metres grading 0.61 per cent copper and 0.55 per cent zinc in a massive pyrrhotite zone;
• 2.32 metres grading 0.56 per cent copper in a massive pyrrhotite zone.

True widths of these historical drill intercepts are unknown.

The geological setting, combined with historical exploration results, indicates potential for additional mineralization along strike and at depth. The property remains underexplored, with multiple target areas identified for follow-up exploration.

The drill program is being managed by J.T. (Jo) Shearer, MSc, DIC, FSEG, mine supervisor (No. 854449), president of Homegold Resources Ltd., who has extensive experience in mineral exploration and project development, including a strong record of obtaining permits supporting exploration and production activities. Favourable engagement with local first nations and the NNTC (Nlaka'pamux Nation Tribal Council) are continuing.

Previous work by Bessor was supervised by Dr. K. Downes, PhD, PGeo.

The company considers the historical exploration results referenced in this news release to be relevant to assessing the exploration potential of the Redhill property. However, a qualified person has not performed sufficient work to verify the historical information, including sampling procedures, analytical methods, and quality assurance/quality control protocols associated with the historical drilling programs. Accordingly, the historical results should not be relied upon as an indication of current or future mineral resources or mineralized systems on the property. The company considers the information reliable for exploration targeting purposes only.

About Copper One Resources Corp.

Copper One Resources is focused on identifying, acquiring and advancing late-stage copper and copper/silver/gold projects to meet the growing global demand for critical metals required for electrification, renewable energy infrastructure and modernization of energy systems.

The company's flagship asset is the Majuba Hill copper-silver-gold district, located 156 miles (251 kilometres) from Reno, Nev. Majuba Hill is an exploration-stage project situated in a mining-friendly jurisdiction with established infrastructure, where continuing work is focused on evaluating the scale and extent of copper mineralization.

In addition, the company has entered into an option agreement to earn up to a 100-per-cent interest in the Redhill property, located south of Ashcroft, B.C., adjacent to the Trans-Canada Highway. The Redhill property hosts volcanogenic massive sulphide (VMS) mineralization, with additional potential for epithermal gold mineralization.

Copper One Resources is advancing its projects through systematic exploration and technical evaluation, with a focus on responsible exploration practices, technical transparency and long-term value creation.
