(CSE: CEXY | OTCID: CEXYF | FSE: IW8 | WKN: A42AGR) (“Copper One” or the “Company”) is pleased to announce the successful completion of its Phase 1 core drilling program consisting of a total of 4,015 feet (1,224 meters) at the Company’s flagship Majuba Hill Copper-Silver-Gold Project, located in Pershing County, Nevada.

The Company is also pleased to report that all site preparations for its 2026 Phase 2 drill program have been completed. Four drill pads and associated drill sites are now fully prepared for the planned 4,000-foot (1,219-metre) Phase 2 program, positioning the Company to commence the next phase of drilling. “The successful completion of the 2026 Phase 1 drill program marks another important milestone in our 2026 exploration program at Majuba Hill," said David Greenway, President and CEO of Copper One. "The drilling successfully intersected the targeted north-northwest-trending breccia corridor, confirming our geological model and providing valuable information on the structural controls and alteration associated with the mineralizing system. The observed tourmaline alteration, brecciation and intrusive relationships enhance our confidence in the evolving geological interpretation and will help refine future drill targeting as we continue to systematically evaluate the scale and continuity of the Majuba Hill copper-silver-gold system.” Click Image To View Full Size Figure 3 : Tourmaline breccia intersected in Hole MHB-38 at approximately 338 feet (103.0 metres), corresponding to the projected north-northwest-trending breccia corridor identified through recent geological mapping. All drill core from the Phase 1 program has been transported to the Company’s secure core facility in Elko, Nevada, where it is currently being logged, photographed, sampled and prepared for shipment to ALS Laboratories.

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, the world's top-ranked mining jurisdiction according to the Fraser Institute's 2025 Annual Survey of Mining Companies. 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, water, and access to a skilled mining workforce. Majuba Hill is a past-producing copper mine with an extensive exploration database, including approximately 89,395 feet (27,248 metres) of historical drilling, 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 mineralized hydrothermal 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.
