Copper One Resources Completes Second 300m Diamond Drill Hole at Redhill Copper-Zinc VMS Project in British Columbia

Second Drill Hole Reaches 300 Metres at Redhill VMS Copper-Zinc Target

On July 15, 2026, Copper One Resources announced the successful completion of its second diamond drill hole at the Redhill Copper-Zinc Project in south-central British Columbia. The hole was drilled to 300 metres to test coincident electromagnetic, magnetic, and geological targets interpreted as prospective for volcanogenic massive sulphide (VMS) mineralization.

The drill hole also aims to assess the continuity of mineralization intersected in historical drilling and to further validate the geological model derived from prior exploration. Paradigm Drilling Ltd. continues to operate a Boyles B-15 hydraulic, track-mounted diamond drill with NQ tooling at the site, capable of reaching depths beyond 600 metres. No assay results from the first or second holes have been disclosed yet; the company will release analytical data once received, validated, and interpreted.

Phase 1 Drill Program: 3,000 Metres Across 10 Holes

The Phase 1 program is designed to test priority VMS targets and build on extensive historical drilling and geophysical surveys that identified copper-zinc and gold-silver mineralization, hydrothermal alteration, and prospective sulphide-bearing volcanic units. The initial program will include approximately 3,000 metres of diamond drilling over 10 holes, with the second hole now completed.

Drilling continues with additional Phase 1 holes planned along prioritized VMS targets. Step-out drilling will evaluate the continuity of VMS-style copper-zinc mineralization along key structural and geophysical trends. No completion timeline for the full Phase 1 program was provided.

CEO David Greenway Highlights Confidence in VMS Exploration

David Greenway, CEO of Copper One Resources, stated: "Completing our second drill hole marks a significant milestone as we systematically assess the Redhill Project's VMS potential. Historical drilling, favorable geology, and multiple coincident geophysical targets reinforce our confidence in the property. We look forward to completing the Phase 1 program and unlocking additional copper and zinc discoveries in one of British Columbia’s established mining districts."

This statement underscores the company’s systematic evaluation approach and confidence based on historical data and geophysical targeting. No production guidance or resource estimates are provided at this exploration stage.

Redhill Property Details: 4,736 Hectares in Kamloops Mining District

The Redhill Property lies south of Ashcroft, BC, within the Kamloops Mining District and is accessible via the Trans-Canada Highway. It comprises 18 mineral claims totaling approximately 4,736.38 hectares (11,703 acres), representing a large contiguous land package in a well-established mining region. Copper One holds an option agreement to earn up to 100% interest in the property.

The property hosts VMS mineralization within sericite-altered felsic volcanic rocks. Historical exploration identified sulphide assemblages including pyrite, pyrrhotite, and chalcopyrite in stringer, semi-massive, and massive sulphide zones. The area correlates with the Kutcho Terrane of northern British Columbia, which hosts the significant Kutcho VMS Deposit, supporting the company’s exploration model.

Historical Drilling by Bessor Minerals Referenced

Historical drilling by Bessor Minerals Inc. in 2022 reported intercepts such as 6.9 metres grading 0.61% copper and 0.55% zinc in a Massive Pyrrhotite Zone, and 2.32 metres grading 0.56% copper in another Massive Pyrrhotite Zone. True widths of these intercepts remain unknown.

The company cautions that a Qualified Person has not verified the historical data, including sampling, analytical methods, and QA/QC protocols. Therefore, these historical results should not be relied upon as indicators of current or future mineral resources and are considered reliable only for exploration targeting. Investors should carefully consider this when evaluating the historical information.

Paradigm Drilling and Technical Management

Copper One engaged Paradigm Drilling Ltd. to conduct the Phase 1 program using a Boyles B-15 hydraulic, track-mounted diamond drill with NQ tooling. Initial drill pads are permitted and under preparation as drilling proceeds along prioritized structural and geophysical trends.

The program is managed by J.T. ("Jo") Shearer, M.Sc., D.I.C., FSEG, Mine Supervisor 854449, President of Homegold Resources Ltd., noted for extensive mineral exploration and project development experience, including permitting. Engagement with local First Nations and the NNTC is ongoing and described as positive.

Qualified Person Review and NI 43-101 Compliance

Technical information in the announcement has been reviewed and approved by Larry Segerstrom, M.Sc. (Geology), CPG, a non-independent consulting geologist and Qualified Person under NI 43-101 standards. This ensures regulatory compliance for public disclosure of technical data.

The Canadian Securities Exchange and its Market Regulator do not accept responsibility for the adequacy or accuracy of the release. All technical data disclosed is preliminary and subject to verification through ongoing drilling and assays.

Copper One’s Broader Portfolio: Majuba Hill Flagship Project

While Redhill is the current drilling focus, Copper One’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 in a mining-friendly jurisdiction with established infrastructure, where work continues to evaluate copper mineralization scale and extent.

The company’s mandate is to identify, acquire, and advance late-stage copper and copper-silver-gold projects to meet global demand for critical metals essential for electrification, renewable energy, and energy system modernization. The Redhill option agreement represents a complementary second primary exploration asset focused on VMS copper-zinc mineralization.

Assay Results Pending for Redhill Drill Holes

No assay results have been released yet for the first or second diamond drill holes at Redhill. The company confirms results will be released once received, validated, and interpreted but provides no specific timeline. The second hole depth is confirmed at 300 metres; the first hole’s depth was not disclosed in this announcement.

The announcement primarily marks drilling progress rather than results disclosure. It confirms ongoing drilling, the geological model’s validity per company assessment, and forthcoming assay data, which are key points for investors and analysts.

VMS Mineralization and British Columbia Mining District Context

Volcanogenic massive sulphide deposits are globally significant base-metal sources, typically containing copper, zinc, lead, gold, and silver. British Columbia’s Kamloops Mining District has a rich history of exploration and development, with established permitting, infrastructure access—including proximity to the Trans-Canada Highway—and relevant geological terranes such as the Kutcho Terrane.

Historical exploration at Redhill, including work by Teck Resources Limited, identified multiple stratabound hydrothermal alteration zones and copper mineralization. The geological setting and historical data suggest potential for additional mineralization along strike and at depth. The property remains underexplored with multiple follow-up target areas, aligning with Copper One’s early-stage systematic drilling exploration thesis.
