COPPER ONE IDENTIFIES NEW COPPER ZONE 600 METRES NORTHEAST OF MAIN ZONE AT REDONDA COPPER-MOLYBDENUM PROJECT, BRITISH COLUMBIA

Copper One Resources Corp. has visually identified a new copper-mineralized zone in stepout drill hole RED-26-04, approximately 600 metres northeast of the main mineralized zone at its 100-per-cent-owned Redonda copper-molybdenum project, located on West Redonda Island, British Columbia.

The discovery was made during the company's fully financed, 2,400-metre diamond drilling program. Semi-massive chalcopyrite, a copper-bearing sulphide mineral, and magnetite were observed at approximately 171.30 metres downhole in RED-26-04. These observations are preliminary, and the presence and grade of copper mineralization remain subject to laboratory analytical confirmation.

David Greenway, president and chief executive officer of Copper One, commented: "The identification of a new zone of strong copper mineralization approximately 600 metres northeast of the main zone marks an exciting development for Copper One and highlights the exploration potential emerging at Redonda. Encountering semi-massive chalcopyrite and magnetite in stepout drill hole RED-26-04 is particularly encouraging as we work to better understand the scale and distribution of mineralization across the property. This zone provides another compelling area for our geological team to investigate and reinforces our confidence in the project's broader exploration potential. While laboratory assays are required to confirm copper grades, these early observations underscore why we believe Redonda represents an important opportunity within our growing portfolio of North American copper assets."

Drill hole RED-26-04 is being drilled at an inclination of minus 52 degrees and is planned to reach a total depth of approximately 200 metres. The hole is designed to investigate mineralization northeast of the main zone and provide additional geological information to support the company's continuing evaluation of the Redonda system.

Drill hole RED-26-03 update

The company also reports that drill hole RED-26-03 has been completed to a total downhole depth of 234.69 metres. The hole was drilled at an inclination of minus 75 degrees.

Redonda hosts an underexplored porphyry copper-molybdenum system within British Columbia's Coast suture zone, a geological belt prospective for porphyry copper mineralization. The current drill program is testing priority targets developed through the integration of historical exploration data, airborne geophysics, recent field mapping and geological interpretation.

The 2026 exploration strategy is informed by the technical report on the Redonda property prepared by W.B. Lennan, PGeo, and filed under the company's SEDAR+ profile in March, 2026. Mr. Lennan has reviewed the planned drill program, and concurs with its objectives, targets and design.

To execute the program, Copper One has engaged Paradigm Drilling Ltd., which has deployed a Boyles T-75 hydraulic, track-mounted diamond drill equipped with NQ tooling and capable of testing targets to depths exceeding 600 metres (1,969 feet).

The Redonda copper-molybdenum project comprises nine mineral claims covering approximately 2,746 hectares (6,786 acres) on West Redonda Island in British Columbia's Vancouver mining division. Exploration conducted since the late 1960s has identified multiple copper-molybdenum mineralized zones that remain open along strike and at depth. Historical exploration by Teck Resources Ltd. (formerly Teck Corp.) in 1979 included nine NQ diamond drill holes totalling 1,681 metres (5,515 feet).

The current drill program is evaluating the extent of the known mineralized system and testing priority targets identified through the company's integrated geological and geophysical interpretation. In addition, recent field observations have identified an area that may represent a previously unrecognized mineralized zone exposed along a historic logging road east of the main trend. This area will be systematically mapped and sampled, and may become an additional drill target, subject to analytical results.

Engagement with the Klahoose First Nation

Copper One is committed to working collaboratively with the Klahoose First Nation throughout the 2026 exploration campaign, with an emphasis on local employment, training opportunities, and the use of Klahoose-owned and affiliated businesses wherever practicable. As part of this commitment, the company has engaged a Klahoose member to perform core splitting and will utilize the Klahoose crew boat for marine transportation during the program.

The company will maintain continuing communication with Klahoose regarding exploration activities, work schedules and project milestones. Exploration activities will be conducted in accordance with applicable cultural heritage protocols and environmental best practices, with Copper One continuing to identify opportunities to support skills development, capacity building and meaningful economic participation as exploration advances.

About Redonda

The Redonda copper-molybdenum project is a district-scale porphyry copper-molybdenum exploration project located on West Redonda Island in British Columbia's Vancouver mining division. The project comprises nine mineral claims covering approximately 2,746 hectares (6,786 acres) and is situated within the highly prospective Coast suture zone, a geological belt known for significant porphyry copper and skarn mineralization.

Redonda lies within the Coast suture zone between the Wrangellia terrane and the Coast plutonic complex. Early Cretaceous dioritic intrusions of the Coast plutonic complex are cut by at least three later intrusive phases: (i) a quartz plug; (ii) a wide, hornblende-rich dike locally brecciated over approximately 600 metres (1,969 feet) of exposed length; and (iii) several smaller feldspar dikes near the southwestern margin of the hornblende body. Copper-molybdenum mineralization is most concentrated along the hornblende dike, particularly within brecciated zones. The geological setting shares certain characteristics with nearby porphyry systems, including the OKover copper-molybdenum deposit, located approximately 34 kilometres (21 miles) to the southeast (north of Powell River), and the Gambier copper deposit in Howe Sound. Mineralization at nearby projects is not necessarily indicative of mineralization at Redonda.
