Copper One Resources Corp. (CSE: CEXY) announced on November 13, 2026, the completion of drill hole MHB-41, the third hole of its 2026 Phase 2 diamond drilling program at its 100%-owned Majuba Hill Copper-Silver-Gold Project in Pershing County, Nevada. The hole reached a final downhole depth of 1,850 feet (564 metres), with preliminary geological logging identifying silicification, sulfide minerals, and tourmaline breccia at multiple depths. No laboratory assay results are being reported at this stage, and investors may be watching closely for analytical results once quality assurance and review are complete.

Key Points

  • Copper One Resources Corp. (CSE: CEXY | OTCID: CEXYF | FSE: IW8)
  • Drill hole MHB-41 completed at 1,850 feet (564 metres) downhole as the third hole of the 2026 Phase 2 program at Majuba Hill, Nevada
  • Three completed Phase 2 holes — MHB-39, MHB-40, and MHB-41 — account for a combined 4,925 feet (1,501 metres) of diamond drilling; the Phase 2 program totals up to 10,000 feet (3,048 metres)
  • Laboratory assay results from MHB-41 are pending; results will be disclosed following receipt and quality assurance review

Preliminary Geology Observed in MHB-41 at Majuba Hill

Preliminary geological core logging of MHB-41 identified pervasive silicification with fine-grained pyrite and chalcopyrite at approximately 580–581 feet downhole, tourmaline breccia within core-box intervals of 808.0–817.6 feet and 1,066.7–1,076.3 feet, and fracture coatings of hematite and tenorite at approximately 1,261 feet (384 metres) downhole. The company emphasised that these are preliminary visual field observations only. The cited tourmaline breccia intervals represent full core-box widths and do not establish continuous mineralised widths. Visual observations do not determine metal grades or confirm economic mineralisation.

Phase 2 Drilling Program Scope and Progress

The 2026 Phase 2 program comprises up to 10,000 feet (3,048 metres) of HQ/PQ diamond core drilling, with an initial scope of approximately 5,000 feet (1,524 metres) contracted to Evolve Exploration Nevada, LLC. Operations are planned on a continuous two-shift, 24-hours-a-day, seven-days-a-week basis. Through Evolve's EVX Connect platform, Copper One states it receives live drilling metrics, digital progressive logs, and high-quality drill core photographs in real time. More than 95,000 feet (28,956 metres) have been drilled at Majuba Hill to date across more than 100 drill holes.

Majuba Hill's Strategic Role in Copper One's Exploration Portfolio

Majuba Hill remains Copper One's flagship asset and is central to the company's North American copper exploration strategy. The property comprises approximately 9,684 acres (3,919 hectares) in Pershing County, Nevada — a jurisdiction that ranked first globally on the Investment Attractiveness Index in the Fraser Institute's Annual Survey of Mining Companies 2025, the release states. The company's objective is to advance the project toward an inaugural mineral resource estimate under National Instrument 43-101. No mineral resource or mineral reserve has been established at Majuba Hill to date.

Qualified Person Sign-Off and Assay Timeline

The scientific and technical content of the announcement was reviewed and approved by Larry Segerstrom, M.Sc. (Geology), CPG, a non-independent consulting geologist and Qualified Person as defined under National Instrument 43-101. The company stated that any material analytical results from MHB-41 will be disclosed following receipt, quality assurance and quality control review, and evaluation by the Qualified Person. The immediate share price impact was not clear from available public information.
