CANADA ONE ANNOUNCES UP TO 13.35% COPPER, 2.32 G/T GOLD AND 18.15 G/T PALLADIUM ASSAY RESULTS FROM THE FRIDAY CREEK ZONE, COPPER DOME PROJECT

Canada One Mining Corp. has provided assay results of its 2025 fall exploration program conducted at the Friday Creek zone on the company's 100-per-cent-owned Copper Dome project in Princeton, B.C.

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 approximately 367 million tonnes grading 0.25 per cent copper, 0.12 gram per tonne gold and 0.69 gram per tonne silver.

Multiple mineralized zones have been identified across the Copper Dome property, with historical drilling confirming high-grade copper associated with northeast-trending structures similar to those hosting mineralization at Copper Mountain.

The field program was completed in Q4 2025 and focused on assessing and sampling historic Minfile occurrences, with particular emphasis on the Friday Creek zone.

Peter Berdusco, president and chief executive officer of Canada One Mining, commented: "These sample results further validate the compelling potential of the Copper Dome project. Copper, gold and palladium grades returned from sampling significantly exceeded the company's expectations, and the extent and style of alteration observed at Friday Creek are extremely encouraging. As a result, the Friday Creek target has been elevated to the company's top exploration priority for 2026, and management believes these results will play a key role in shaping upcoming exploration programs and future drill targeting."

Mineralization consistent with alkalic copper-gold porphyry systems

Preliminary assay results from surface rock samples indicate the presence of copper, gold and palladium mineralization, consistent with alkalic copper-gold porphyry systems.

Nine rock samples from the program returned copper grades exceeding 0.5 per cent, including six overlimit grab samples with grades ranging from 1.132 per cent to 13.35 per cent copper. These results highlight the prospective nature of the Friday Creek area.

Potential importance of platinum group elements (PGEs)

The program also identified significant palladium enrichment in multiple samples. Three samples returned values exceeding one gram per tonne palladium, with one sample grading 18.15 grams per tonne palladium. This observation is consistent with characteristics reported at several British Columbia mines and deposits, including Galore Creek, Mount Milligan, Mount Polley, New Afton/Afton and Ajax.

Historically, PGEs in alkalic systems have received limited exploration focus. Recent advances in geological research, however, suggest that these deposits may represent a significant secondary source of PGE resources globally, underscoring the importance of considering PGEs in future exploration strategies.

Prominent potassic alteration associated with alkalic copper-gold porphyry systems

Based on field observations and associated sample metadata collected during the 2025 program, copper, gold, silver and palladium mineralization is consistently associated with chalcopyrite-bornite sulphide assemblages, accompanied by potassic alteration characterized by K-feldspar, biotite and quartz in hand specimens.

The Friday Creek zone, located on the western part of the claim block, exhibits prominent potassic alteration with visible chalcopyrite and bornite mineralization. Samples from Friday Creek returned the highest copper-gold-palladium values of the program, including copper grades of 13.35 per cent, 6.59 per cent, 5.76 per cent, 2.16 per cent and 1.30 per cent copper.

Sampling at Friday Creek covered an area of approximately 150 metres by 150 metres, where outcrop exposure was limited. Despite this, the zone represents a notable surface expression of bornite-rich mineralization and intense potassic alteration.

Historical drilling at Friday Creek

In 2006 and 2007, a total of 14 drill holes were completed at the Friday Creek zone, with an average depth of 153.8 metres. These relatively shallow holes targeted the copper, gold, palladium and platinum potential of the zone and surrounding areas, which are hosted within altered volcanic and intrusive rocks of the Copper Mountain district. Historic assessment reports suggest that seven of these holes intercepted copper mineralization in the form of chalcopyrite stringers and copper oxide mineralization.

About the Copper Dome project

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

Historical work completed:

• Geophysics: 51 kilometres 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: greater than 8,900 metres of diamond drilling;
• Trenching: over one kilometre excavated.

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

Acknowledgment

Canada One acknowledges that the Copper Dome project is located within the traditional, ancestral and unceded territory of the Smelqmix people. The company recognizes and respects their cultural heritage and relationship to the land, honouring their past, present and future.

Historical work

Certain technical information relating to the Copper Dome project is based on historical work and records prepared by previous operators. Work was done to the standards of the time and is considered historical in nature and is not National Instrument 43-101 compliant and cannot be relied upon. The results are listed here to show why the company is interested in this area. A qualified person has reviewed the available information for reasonableness; however, further work is required to verify portions of the historical data and future work and drilling may not repeat similar results.

Quality assurance/quality control (QA/QC)

All rock samples collected from the fall 2025 fieldwork program were submitted to ALS Geochemistry in Kamloops to be analyzed for gold and PGEs (PGM-ICP24 50-gram fire assay) and multielement geochemistry, including elements copper, lead, zinc, cobalt and silver (method ME-MS61).
