Copper One Resources (CEXYF) completed MHB-41, the third hole of its 2026 Phase 2 drilling program at Majuba Hill in Nevada. The hole reached 1,850 feet (564 metres), bringing completed drilling across three Phase 2 holes to 4,925 feet (1,501 metres).
Preliminary core logging identified silicification, or silica alteration, with pyrite and chalcopyrite, tourmaline breccia—fragmented rock—and fracture coatings of hematite and tenorite. These visual observations do not establish metal grades or economic mineralization; no MHB-41 laboratory assay results are reported.
The expanded program comprises up to 10,000 feet (3,048 metres), with approximately 5,000 feet (1,524 metres) initially contracted to Evolve Exploration Nevada. Copper One intends the program to test priority targets and support advancement toward an inaugural mineral resource estimate under NI 43-101, Canada's mineral-project disclosure standard.
Copper One Resources (CEXYF) completed MHB-40, the second hole of its 2026 Phase 2 drilling program at Majuba Hill in Nevada. The hole reached 1,615 feet (492 metres), bringing combined drilling with MHB-39 to 3,075 feet (937 metres). Preliminary logging identified possible porphyry D-type veins associated with quartz-sericite-pyrite alteration, a change in the rock's mineral composition. Visual mineral identification is preliminary and does not substitute for laboratory assays.
The expanded program covers up to 10,000 feet (3,048 metres), with an initial approximately 5,000 feet (1,524 metres) contracted to Evolve Exploration Nevada. Copper One plans continuous, two-shift operations and aims to advance the wholly owned project toward its first mineral resource estimate under NI 43-101, Canada's mineral-project disclosure standard.
Copper One Resources (CEXYF) will automatically convert 19,889,750 special warrants into common shares and purchase warrants on November 6, 2026.
The conversion will deliver 19,889,750 common shares and 9,944,875 share purchase warrants. The special warrants were issued September 29, 2026, comprising 12,383,000 non-flow-through and 7,506,750 flow-through special warrants. A prospectus supplement dated November 3, 2026 qualifies the underlying securities for distribution in British Columbia, Alberta and Ontario.
Each purchase warrant allows acquisition of one common share at $0.50 until 4:00 p.m. Pacific Time two years after the offering closed. Copper One may accelerate expiry to 30 days after notice if its common shares trade at or above $1.25 for five consecutive trading days.
Copper One Resources (CEXYF) completed the first hole of its Phase 2 drilling program at its wholly owned Majuba Hill project in Nevada.
MHB-39 reached 1,460 feet, beyond its originally planned 1,000–1,250-foot range, after persistent silicification—alteration involving silica—prompted an extension. Visually identified native copper occurred at 1,090 feet and copper oxides at 820 feet. These observations are preliminary and do not establish metal grades or economic significance; laboratory analysis is required.
Phase 2 comprises up to 10,000 feet of diamond core drilling, with approximately 5,000 feet initially contracted to Evolve Exploration Nevada. Copper One intends the program to test priority targets and support advancement toward a maiden mineral resource estimate under NI 43-101, Canada's mineral disclosure standards. Assays from the completed 2026 Phase 1 program remain pending review and validation.
Copper One Resources (CEXYF) will attend Market Bridge Live in London on November 4, 2026, and the Munich Mining Conference. The Munich event runs November 6–7, 2026, at the AMERON Hotel München; the London event takes place at Saddlers’ Hall.
The company plans to showcase its North American copper exploration portfolio to European investors, highlighting ongoing Phase 2 drilling at the Majuba Hill Copper-Silver-Gold Project in Nevada and advancing exploration at the Redonda Copper-Molybdenum Project in British Columbia.
