Copper One Expands Phase 2 Drill Program to Up to 10,000 Feet and Engages Evolve Exploration Nevada at Majuba Hill Copper-Silver-Gold Project

Copper One Resources Corp. (CSE: CEXY | OTCID: CEXYF | FSE: IW8 | WKN: A42AGR) (“Copper One” or the “Company”) is pleased to announce that it has engaged Evolve Exploration Nevada, LLC ( “Evolve” ) to undertake diamond core drilling at its 100%-owned flagship Majuba Hill Copper-Silver-Gold Project ( “Majuba Hill” or the “Project” ) in Pershing County, Nevada, under a drilling services agreement dated September 15, 2026 (the “Agreement” ). The Company is also pleased to announce that it has expanded its planned Phase 2 diamond core drilling program (the “Phase 2 Program” ) to up to 10,000 feet (3,048 metres) of HQ/PQ diamond core drilling. The expanded Phase 2 Program is intended to accelerate systematic testing of priority targets at Majuba Hill and support the Company’s objective of advancing the Project toward a maiden mineral resource estimate prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects ( "NI 43-101" ). More than 90,000 feet (27,432 metres) have been drilled to date at Majuba Hill in more than 100 drill holes. Assay results from the completed 2026 Phase 1 drill program remain pending. The Phase 2 Program is expected to commence on or about October 1, 2026.

David Greenway, President and Chief Executive Officer of Copper One, stated: "Expanding the Phase 2 Program to up to 10,000 feet allows us to test additional priority targets and build on the geological information generated by the Phase 1 program. Evolve brings the personnel, equipment and operational experience required for this next stage of drilling. Its EVX Connect platform is expected to give our technical team timely access to drilling metrics, digital reporting, drill-hole tracking and core photographs, supporting efficient communication and informed decisions as the program advances."

Phase 2 Program Highlights Expanded program of up to 10,000 feet (3,048 metres) of diamond core drilling. Initial approximately 5,000 feet (1,524 metres) contracted to Evolve using one portable HQ/PQ core drill. Continuous, two-shift drilling operations planned on a 24-hour-per-day, seven-day-per-week basis. Maximum planned hole depth under the initial scope of approximately 1,700 feet (518 metres), with final collar locations, azimuths, inclinations and depths to be determined by the Company’s technical team. Real-time operational visibility through Evolve’s EVX Connect platform.

Real-Time Drill Program Technology Every Evolve drill rig operates on EVX Connect, Evolve’s real-time operational platform. Through EVX Connect, Copper One expects to receive live drilling metrics, digital PLOD reporting, drill-hole coordinate tracking, streamlined invoicing and high-quality photographs of drill core as it is recovered. Information will be accessible through web and mobile interfaces, providing the Company’s technical and management teams with timely visibility into drilling progress and field operations.
