Copper One Resources Corp. (CSE: CEXY) has announced the completion of drill hole MHB-40, the second 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 1,615 feet (492 metres), with preliminary core logging identifying possible porphyry D-type veins associated with pervasive phyllic alteration. The Phase 2 program encompasses up to 10,000 feet of diamond core drilling, with the company targeting an inaugural NI 43-101 mineral resource estimate. Investors may be watching for assay results and further geological interpretation as the program continues.

Key Points

  • Copper One Resources Corp. (CSE: CEXY | OTCID: CEXYF | FSE: IW8)
  • Drill hole MHB-40 completed at Majuba Hill, Nevada, reaching 1,615 feet (492 metres) with possible porphyry D-type veins identified in preliminary core logging
  • MHB-39 and MHB-40 together account for 3,075 combined feet (937 metres) drilled under the Phase 2 program; total historical drilling at Majuba Hill exceeds 95,000 feet across more than 100 holes
  • Assay results from MHB-40 are pending; visual identification is preliminary and not a substitute for laboratory results

MHB-40 Drill Results and Geological Observations at Majuba Hill

Drill hole MHB-40 was drilled on an azimuth of 030° at an inclination of −55°, reaching a final depth of 1,615 feet (492 metres). Preliminary core logging identified possible porphyry D-type veins associated with pervasive quartz-sericite-pyrite alteration. The company cautions that visual identification is preliminary and should not be considered a substitute for laboratory assay results. These observations follow the detection of native copper and copper oxides in the first Phase 2 hole, MHB-39, suggesting a progression of mineralogical features across successive drill holes that geologists are evaluating for deeper system significance.

Phase 2 Program Scope and Drilling Technology at Majuba Hill

The expanded Phase 2 program targets up to 10,000 feet (3,048 metres) of HQ/PQ diamond core drilling, contracted to Evolve Exploration Nevada, LLC. An initial scope of approximately 5,000 feet (1,524 metres) utilises one portable core drill operating on continuous two-shift, 24-hours-a-day, seven-days-a-week operations. Copper One receives real-time operational data through Evolve's EVX Connect platform, including live drilling metrics, digital reporting, coordinate tracking, and high-quality drill core photographs. The maximum planned hole depth under the initial scope is approximately 1,700 feet (518 metres), with final collar locations determined by the company's technical team.

Majuba Hill Project Context and Resource Estimate Objective

Majuba Hill is a past-producing copper mine spanning approximately 9,684 acres (3,919 hectares) in Pershing County, Nevada, situated approximately 156 miles (251 kilometres) northeast of Reno. More than 95,000 feet of drilling has been completed across more than 100 historical and recent holes. The Phase 2 program is designed to accelerate systematic testing of priority targets and support the company's objective of advancing toward an inaugural NI 43-101 mineral resource estimate. No mineral resource or mineral reserve has been established at Majuba Hill, and no assurance exists that ongoing exploration will result in such a definition.
