Vancouver, British Columbia–(Newsfile Corp. – July 7, 2026) – Canada One Mining Corp. (TSXV: CONE) (OTC Pink: COMCF) (FSE: AU31) (“Canada One” or the “Company“) is pleased to provide an exploration update following the 2026 Phase 1 exploration program conducted at its 100% owned Copper Dome Project, (“Copper Dome”, “Project” or “Property”), Princeton B.C.
2026 PHASE 1 FIELD PROGRAM HIGHLIGHTS
- Crews established 16 field stations with full metadata across the property, systematically documenting geological observations to contextualize mineral showings in relation to property-scale and regional geology.
- A total of 12 rock samples were collected during the first phase of exploration and have been delivered to the laboratory for analysis.
- Detailed 1:5,000-scale geological and alteration mapping across the Boundary Zone and Friday Creek targets
- Continued prospecting of underexplored areas of the property, including the Copper Dome South and Copper Dome East zones.
Peter Berdusco, President and CEO of the Company, commented: “We are excited about the first phase of the 2026 exploration program. Advancing our understanding of the mineral systems at Copper Dome is key to guiding our systematic, multi-phase field programs. This work represents a strong start to the 2026 field season and will help inform subsequent exploration phases.”
Exploration Summary
Crews completed the Phase 1 field program at the Copper Dome Project, with work focused on systematic geological mapping, prospecting, and the refinement of known mineralized zones.
During the program, 16 field stations were established across the property, with full metadata collected at each site to support consistent geological interpretation and property-scale context. A total of 12 rock samples were collected and submitted to ALS Geochemistry in Kamloops for analysis.
Detailed 1:5,000-scale geological and alteration mapping was completed across the Boundary Zone and Friday Creek targets, providing improved definition of lithological contacts, alteration patterns, and mineralized trends. Field crews also continued prospecting in underexplored areas of the property, including the Copper Dome South and Copper Dome East zones.
Work at the Friday Creek showing focused on delineating surface mineralization and improving geological understanding of the system. Efforts were focused on zones where chalcopyrite stringers, mineralized breccia cement, and bornite clots and stringers were observed on surface during the 2025 field season (see Figure 2 from 2025 field program).
Historical and newly identified geological features were documented to support ongoing interpretation and target generation for future exploration phases.

All rock samples collected from the 2026 fieldwork program are pending and were submitted to ALS Geochemistry – Kamloops to be analyzed for gold and platinum group elements (50 g fire assay), and multi-element geochemistry, including elements Cu, Pb, Zn, Co, and Ag (method ME-MS61).
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 the company reports as having Proven and Probable Reserves of ~367 Mt at 0.25 % Cu, 0.12 g/t Au, and 0.69 g/t Ag (Hudbay Minerals Inc., 2023). 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 technical and scientific information regarding the adjacent Copper Mountain Mine is sourced from Hudbay Minerals Inc.’s published reports. Mineralization at Copper Mountain should not be considered indicative of the mineralization on the Copper Dome Project.
The Copper Dome 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.
