CANADA ONE COMMENCES 2025 FIELD WORK PROGRAM AT FLAGSHIP, COPPER DOME PROJECT

Canada One Mining Corp. has launched its 2025 field exploration program at its flagship Copper Dome project, located 18 kilometres (km) south of Princeton, B.C.

2025 field work program highlights:

• Priority target: Boundary zone -- one by two km Cu-Au (copper-gold) soil anomaly;
• Follow-up targets: Friday Creek, Combination, Haul Road zones (mapping plus rock sampling);
• Work streams: detailed geological mapping, systematic rock geochemistry and alteration mapping;
• Core program: relog, catalogue and reinterpret historical core around key intercepts;
• Outcome: ranked, data-driven target matrix to guide next steps toward drill targeting.

Peter Berdusco, president and chief executive officer of the company, commented: "We are excited to kick off our 2025 fieldwork at Copper Dome. The Boundary zone, a recently identified one by two km Cu-Au anomaly with historical rock samples up to 43 per cent Cu, will anchor our systematic mapping and geochemistry. In parallel, we will refine the Friday Creek, Combination and Haul Road zones, and relog historical core to deliver a ranked, data-driven target matrix."

2025 fieldwork program summary

The 2025 program will prioritize exploration of the Boundary zone, a newly defined target characterized by a one by two km copper-gold soil geochemical anomaly. Historical rock sampling on the western margin of the Boundary zone returned exceptional assays of up to 43 per cent Cu, 28.16 grams per tonne (g/t) Au and 18.19 g/t palladium (Pd). Given the limited historical work in this area, the company's field efforts will focus on systematic geochemical rock sampling and detailed geological mapping. This work aims to better understand the nature of copper-gold mineralization, identify alteration assemblages, and evaluate the proximity of potential porphyry centres relative to the Boundary zone.

In addition, follow-up rock sampling and geological mapping will be conducted on the Friday Creek, Combination and Haul Road zones, which are adjacent to the Boundary zone. The Friday Creek and Combination zones have seen limited historical diamond drilling that tested both geophysical and geochemical anomalies, with notable results including:

• DDH FC-01: 8.0 metres (m) grading 0.55 per cent Cu and 2.8 g/t Au;
• DDH FC-02: 15.0 m grading 0.32 per cent Cu and 0.98 g/t Au;
• DDH FC-12: 42.5 m grading 0.28 per cent Cu, including 6.0 m grading 1.5 per cent Cu and 0.70 g/t Au;
• DDH FC-10-17: 19.5 m grading 0.71 per cent Cu, including 2.0 m grading 4.08 Cu;
• DDH FC-18: 102.7 m grading 0.14 per cent Cu, including 20.0 m grading 0.64 per cent Cu.

Understanding the geological framework of these zones will be critical in developing a comprehensive target matrix for future drill testing. The company's objective is to define the specific geological settings of each target and identify those with the most favourable characteristics for copper-gold porphyry centres.

As part of the 2025 program, field crews will also evaluate the condition of historical drill core for relogging, cataloguing and reinterpretation, with particular attention to the most significant historical intercepts.

About the Copper Dome project

Copper Dome is located in the lower Quesnel trough porphyry belt, one of British Columbia's most prolific mining districts. The project directly adjoins Hudbay Minerals Inc.'s producing Copper Mountain mine to the north, which hosts proven and probable reserves of 702 million tonnes grading 0.24 per cent Cu, 0.09 g/t Au and 0.72 g/t Ag. Multiple mineralized zones have been identified across the property, with historical drilling confirming high-grade copper associated with northeast-trending structures similar to those hosting mineralization at Copper Mountain.

The project benefits from excellent infrastructure, enabling year-round access, cost-efficient exploration and a stable, low-risk jurisdiction.

Historical work completed:

• Geophysics: 51 km of induced polarization (IP); airborne magnetic and electromagnetic (EM) coverage over approximately 50 per cent of the property;
• Sampling: 2,253 soils and 378 rocks collected;
• Drilling: 8,900-plus m of diamond drilling;
• Trenching: over one km excavated.

With a five-year drill permit in place, the company is focused on advancing the project toward drill-ready target definition.
