Vancouver, British Columbia–(Newsfile Corp. – April 7, 2026) – Canada One Mining Corp. (TSXV: CONE) (OTC Pink: COMCF) (FSE: AU31) ("Canada One" or the "Company") is pleased to provide assay results of its 2025 fall exploration program conducted at the Friday Creek Zone on the Company’s 100% owned Copper Dome Project, Princeton B.C. ("Copper Dome", "Project" or "Property").
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 ~367 Mt grading 0.25% Cu, 0.12 g/t Au, and 0.69 g/t Ag.1
Multiple mineralized zones have been identified across the Copper Dome property, with historical drilling confirming high-grade Cu 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 CEO 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 Cu-Au Porphyry Systems
Preliminary assay results from surface rock samples indicate the presence of Cu, Au, and Pd mineralization, consistent with alkalic Cu-Au porphyry systems.
Nine rock samples from the program returned Cu grades exceeding 0.5%, including six over-limit grab samples with grades ranging from 1.132% to 13.35% Cu. These results highlight the prospective nature of the Friday Creek area.
Potential Importance of Platinum Group Elements (PGEs)
The program also identified significant Pd enrichment in multiple samples. Three samples returned values exceeding 1 g/t Pd, with one sample grading 18.15 g/t Pd. This observation is consistent with characteristics reported at several British Columbia mines and deposits, including Galore Creek, Mt. Milligan, Mt. 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 Cu-Au Porphyry Systems
Based on field observations and associated sample metadata collected during the 2025 program, Cu, Au, Ag and Pd mineralization is consistently associated with chalcopyrite-bornite sulfide 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 Cu-Au-Pd values of the program, including Cu grades of 13.35%, 6.59%, 5.76%, 2.16%, and 1.30% Cu.
Sampling at Friday Creek covered an area of approximately 150 m by 150 m, 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 m.2 These relatively shallow holes targeted the Cu, Au, Pd, and Pt 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 Cu mineralization in the form of chalcopyrite stringers and Cu oxide mineralization.
