Copper One Resources (CSE:CEXY) has expanded its Phase 2 diamond drilling program at the Majuba Hill Copper-Silver-Gold Project in Nevada, the US, to as much as 3,048m.
The company has engaged Evolve Exploration Nevada to carry out drilling under an agreement dated 15 September 2026, with the program expected to begin around 1 October.
An initial 1,524m of HQ/PQ diamond core drilling has been contracted to Evolve, while Copper One has scope to extend the campaign to the full 3,048m.
Drilling is planned to operate continuously across two shifts, 24 hours a day and seven days a week.
The initial scope allows for drill holes to reach around 518m, although final collar locations, azimuths, inclinations, and depths will be determined by Copper One’s technical team.
Copper One says the expanded program is designed to accelerate testing of priority targets and advance Majuba Hill towards a maiden mineral resource estimate prepared under National Instrument 43-101 – Standards of Disclosure for Mineral Projects (NI 43-101).
The project has seen more than 27,432m of drilling across more than 100 drill holes to date.
Assay results from Copper One’s completed 2026 Phase 1 program remain pending.
CEO David Greenway says the larger Phase 2 program will allow the company to test additional targets while building on geological information gathered during the first phase.
“Expanding the Phase 2 Program to up to 10,000 feet allows us to test additional priority targets and build on the geological information generated by the Phase 1 program,” Greenway says.
Evolve will also provide Copper One with access to its EVX Connect platform, which delivers live drilling metrics, digital reporting, drill hole tracking, and photographs of recovered core.
Copper One expects the technology to provide its technical and management teams with greater visibility over drilling progress and field operations.
Phase 2 targets
Preparations for the next phase include road construction along a ridge leading towards the planned 26DPH-8 drill pad.
Copper One is also assessing mineralisation observed during Phase 1 drilling, including chalcopyrite and pyrrhotite identified within a breccia zone in drill hole MHB-37B at around 604m depth.
The company says the visual identification is preliminary and should not be considered a substitute for laboratory assay results.
Majuba Hill covers about 3,919 hectares in Pershing County and sits around 251km northeast of Reno.
The past-producing copper project hosts what Copper One describes as a large copper-silver-gold hydrothermal mineralised system that remains open for expansion.
Current exploration is focused on drilling, geological mapping, geochemical sampling, and structural interpretation to better define the scale and continuity of the mineralised system.
The project also benefits from year-round road access, nearby power and water, and access to Nevada’s established mining workforce, according to Copper One.
Beyond Majuba Hill, Copper One owns the Redonda Copper-Molybdenum Project in British Columbia and holds an option to earn up to a 100% interest in the Redhill Property, also in British Columbia.
The company has also proposed acquiring Rooinek Mining, which would add the Sport Project in Utah to its North American copper portfolio.
