Vancouver, British Columbia--(Newsfile Corp. - April 1, 2026) - Canada One Mining Corp. (TSXV: CONE) (OTC Pink: COMCF) (FSE: AU31) ("Canada One" or the "Company") is pleased to provide a corporate update on its 100%-owned Copper Dome Project ("Copper Dome", the "Project" or the "Property") near Princeton, British Columbia.
Project Highlights
The Project directly adjoins the producing Copper Mountain Mine, owned and operated by Hudbay Minerals Inc., which reports Proven + Probable reserves at 347 Mt grading 0.25% Cu, 0.12 g/t Au, and 0.69 g/t Ag, supporting a 21-year mine life to 20451
Assay results from the Friday Creek Zone, generated from rock samples collected during the fall 2025 exploration program, will be released in April
Historical rock sampling at the Friday Creek Zone returned values up to 10.65% Cu, 4.89 g/t Au and 10.40 g/t Pd and the zone displays encouraging porphyry-style alteration and mineralization
Copper Dome has a five-year drill permit in hand, with the Boundary Zone identified as a key drill-target area
Prior work by the Company at the Boundary Zone defined a broad 1,000 m by 1,750 m Cu-Au anomalous corridor, additional follow-up work is planned in 2026
The Combination Creek Zone hosts 5,732 m of historical drilling in 22 holes, including 20 m of 0.64% and 69 m of 0.21% Cu.
The Reco target has added high-grade Au-Ag-Cu upside, including rock sample assays up to 9.96 g/t Au, 9.62 g/t Ag and 0.78% Cu, with additional follow-up work planned in 2026
Peter Berdusco, President and Chief Executive Officer of Canada One commented: "The progress made at Copper Dome has been meaningful on multiple fronts. We expanded the land package, strengthened our permitting position, advanced our understanding of several priority target zones and added high-grade results that broaden the opportunity set at the Project. With proximity to Hudbay Minerals' producing Copper Mountain Mine and Kodiak Copper's MPD Project, we believe Copper Dome is becoming a more robust and better-defined exploration story. We will continue refining and advancing drill-targets and look forward to sharing our Friday Creek rock sample results in April."
Project Review
Copper Dome today stands on a larger and more compelling foundation, supported by an expanded land package, a five-year drill permit, multiple priority target areas and encouraging results that continue to broaden the Company's exploration opportunity.
The Project has expanded with the acquisition of the 4,836-hectare Copper Dome North area, and subsequent staking of Copper Dome East area, and currently totals 12,833 hectares.
This larger land position gives the Company broader control over a highly prospective Cu-Au setting adjacent to Hudbay Minerals' producing Copper Mountain Mine and creates more room to evaluate multiple mineralized corridors and target settings within one consolidated project area.
Copper Dome's location remains one of its defining strengths. The Project directly adjoins the mine and lies within the lower Quesnel Trough porphyry belt, one of British Columbia's best-known copper-producing regions. In addition to its geological setting, the Project benefits from year-round access and established infrastructure, supporting cost-effective exploration and efficient project advancement.
With a five-year drill permit now in hand, Canada One has the flexibility to continue refining targets and progressing the most compelling zones toward drill-ready definition.
Boundary Zone
The Boundary Zone has been identified by the Company as a primary drill-targeting focus, reflecting its location near Copper Mountain and the scale of its Cu-Au signature. Past work has outlined a broad north-northeast trending Cu-Au anomalous corridor measuring approximately 1,000 m wide by 1,750 m long. The zone remains open toward Copper Mountain to the north-northeast and to the south-southwest. Numerous mobile metal ion copper values exceed 10,000 ppb, while elevated potassium values indicate potassic alteration, a key feature commonly associated with porphyry copper systems. Taken together, these characteristics continue to support the Boundary Zone as one of the Project's most important Cu-Au targets.
Combination Creek Zone
Combination Creek provides an additional layer of technical support for the broader Copper Dome exploration model. Historical work at the zone includes 5,732 m of diamond drilling in 22 holes, with notable intercepts including 20 m of 0.64% Cu in hole PT-12-26 and 69 m of 0.21% Cu in hole PT-11-21. These results demonstrate the presence of meaningful copper mineralization within the Project area and reinforce the Company's view that Copper Dome hosts multiple target zones worthy of continued advancement.
Friday Creek Zone
At the Friday Creek Zone, the Company continues to see signs consistent with a prospective porphyry-style environment. Historical rock sampling has returned values up to 10.65% Cu, 4.89 g/t Au and 10.40 g/t Pd, while more recent field observations identified bornite and chalcopyrite associated with strong potassic alteration, including K-feldspar and biotite alteration. Canada One believes Friday Creek represents one of the more compelling target areas on the Property and an important part of the Project's evolving exploration pipeline. Assay results from the zone, generated from samples collected during the fall 2025 exploration program and submitted to ALS Geochemistry - Kamloops, will be released in April.
The Reco Target
The Reco target has introduced an important high-grade dimension to the Copper Dome story. In February 2026, the Company reported rock samples grading up to 9.96 g/t Au, 9.62 g/t Ag and 0.78% Cu, as well as 8.17 g/t Au, 6.83 g/t Ag and 1.75% Cu. Historical and recent work at the broader Haul Road area has also highlighted strong Au and Cu values, including select rock samples up to 93.3 g/t Au. These results suggest Copper Dome may host not only porphyry-related Cu-Au potential, but also structurally controlled higher-grade Au-Ag-Cu opportunities that can add further upside to the Project.
Copper Dome South
Copper Dome South tenure block covers an extension of the Nicola Group volcanic sequence, the same Triassic host rocks that contain the major Cu-Au deposits of Copper Mountain and the Ingerbelle deposit. Historical work including surface sampling, backpack drilling and a 2009 Titan-24 survey, identified broad, high-chargeability zones and anomalous geochemical values at surface are comparable in strength to anomalies overlying the active Copper Mountain pits, suggesting a potential buried mineral system continuing southward onto the Property.
Field Work
Canada One's recent fieldwork has also helped strengthen the Project technically. During the 2025 Phase 2 program, crews established 53 field stations across the Property and collected 29 rock samples, while observing copper sulphides including bornite and chalcopyrite in several areas. This work has improved the Company's geological context across the Property and is helping refine priorities for the next stage of exploration. At Reco a larger-scale prospecting, mapping and sampling program is planned in 2026 to better define the extent and controls of mineralization.

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 367 Mt grading 0.25% Cu, 0.12 g/t Au, and 0.69 g/t Ag1. 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 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 ~50% of the Property.
- Sampling: 2,253 soils and 378 rocks collected.
- Drilling: 8,900+ m of diamond drilling.
- Trenching: Over 1 km excavated.
With a five-year drill permit in place, the Company is focused on advancing the Project toward drill-ready target definition.
