Copper One Resources Corp. Drilling Commenced at The Redhill Copper-Zinc Project, British Columbia

The Phase 1 drill program is designed to test priority volcanogenic massive sulphides ("VMS") targets and follow up on extensive historical drilling and geophysical work that identified copper-zinc and gold/silver mineralization, hydrothermal alteration, and prospective sulphides-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.

David Greenway, Chief Executive Officer of Copper One, commented: "We are excited to begin drilling at Redhill and advance what we believe is a highly prospective VMS exploration opportunity in British Columbia. This program represents an important milestone for Copper One as we continue building a diversified portfolio of copper-focused exploration assets in top-tier mining jurisdictions. With strong geological indicators, historical mineralization, and multiple untested targets, we believe Redhill has the potential to deliver significant exploration upside."

To execute the program, Copper One has engaged Paradigm Drilling Ltd. ("Paradigm Drilling"), 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 step-out 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, British Columbia, within the Kamloops Mining District, and is accessible via the Trans-Canada Highway. The Property comprises eighteen (18) mineral claims totaling 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 Limited 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% copper and 0.55% zinc in a Massive Pyrrhotite Zone

• 2.32 metres grading 0.56% copper in a Massive Pyrrhotite Zone

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, M.Sc., D.I.C., FSEG, Mine Supervisor 854449, President of Homegold Resources Ltd., who has extensive experience in mineral exploration and project development, including a strong track record of obtaining permits supporting exploration and production activities. Favorable engagement with local First Nations and the NNTC are ongoing.

Previous work by Bessor was supervised by K.Downes, Ph.D., P.Geo.

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 QA/QC 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 Corp. 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, Nevada. Majuba Hill is an exploration-stage project situated in a mining-friendly jurisdiction with established infrastructure, where ongoing 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% interest in the Redhill Property, located south of Ashcroft, British Columbia, 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.
