Vancouver, BC – November 6, 2026 – TheNewswire - Copper One Resources Corp. (“Copper One”) (CSE: CEXY | OTCID: CEXYF | FSE: IW8 | WKN: A42AGR) (the “Company”) announces the completion of drill hole MHB-40, the second hole of its 2026 Phase 2 diamond drilling program of up to 10,000 feet at its 100%-owned flagship Majuba Hill Copper-Silver-Gold Project (“Majuba Hill” or the “Project”) in Pershing County, Nevada.

MHB-40 reached a final downhole depth of 1,615 feet (492 metres). Preliminary core logging identified possible porphyry D-type veins associated with pervasive phyllic alteration characterized by quartz, sericite and pyrite.

MHB-40 Highlights

• Hole orientation: MHB-40 was drilled on an azimuth of 030° at an inclination of −55°. 

• Veining and alteration: Core logging identified possible D-type veins associated with pervasive quartz-sericite-pyrite alteration. 

• Phase 2 drilling to date: MHB-40 and the previously completed MHB-39 account for a combined 3,075 feet (937 metres) of diamond drilling. 

David Greenway, President and Chief Executive Officer of Copper One, commented: “We’re advancing copper exploration across our North American portfolio, with drilling at Majuba Hill in Nevada and Redonda in British Columbia. New copper supply takes years to develop, and the work we do today helps us decide which targets warrant further drilling. At Majuba Hill, we continue to see encouraging features in our Phase 2 drill core. Our geologists observed native copper and copper oxides in MHB-39, followed by possible porphyry D-type veins associated with quartz-sericite-pyrite alteration in MHB-40. We’re evaluating whether those veins mark an upper level of the porphyry system and could help guide deeper drilling.”

About the Majuba Hill Copper-Silver-Gold Project, Nevada

Majuba Hill is Copper One Resources Corp.’s flagship copper-silver-gold exploration project, located in Pershing County, Nevada, USA. Nevada ranked first globally on the Investment Attractiveness Index in the Fraser Institute’s Annual Survey of Mining Companies 2025. The property comprises approximately 9,684 acres (3,919 hectares) and is situated approximately 70 miles (113 road kilometres) southwest of Winnemucca and 156 miles (251 kilometres) northeast of Reno.

The project benefits from excellent infrastructure, including year-round road access, nearby electrical power and water, and access to a skilled mining workforce. Majuba Hill is a past-producing copper mine with an extensive exploration database, including records from historical and recent drilling programs, providing a strong technical foundation for ongoing exploration aimed at further defining the extent and economic potential of the mineralized system.

Exploration has outlined a large copper-silver-gold hydrothermal mineralized system that remains open for expansion. Current exploration is focused on advancing the Company's geological model through systematic drilling, geological mapping, geochemical sampling, and structural interpretation to evaluate the scale, continuity, and significance of mineralization. Additional drilling and technical studies will be required to further define the extent and economic potential of the mineralized system.
