Canada One Announces 2026 Two-Phase Exploration Program to Advance High-Priority Porphyry Targets at Copper Dome

Vancouver, April 29, 2026 - Canada One Mining Corp. (TSXV: CONE) (OTC Pink: COMCF) (FSE: AU31) ("Canada One" or the "Company") is pleased to announce its planned 2026 exploration work program, designed to systematically advance high-priority porphyry targets through a combination of geological mapping, geochemical sampling, and geophysical surveys on the Company's 100%-owned flagship Copper Dome Project, ("Copper Dome", "Project" or "Property") located adjacent to Hudbay Mineral Inc.'s producing Copper Mountain Mine, Princeton, B.C.

The program integrates conventional and responsible exploration practices, with a focus on disciplined capital allocation, efficient workflow sequencing, and adaptive targeting strategies. The staged approach is intended to progressively refine targets while maintaining flexibility based on results.

PROGRAM HIGHLIGHTS

• Planned definition and ranking of high-quality porphyry targets through a disciplined two-phase exploration strategy

• Phase 1: refining high-priority targets with mapping, soils, and prospecting

• 1,200 soil samples planned across Friday Creek and Boundary Zone

• Phase 2: 20 line-km of IP surveying to support subsurface targeting

• Drone magnetics to further enhance target definition

Peter Berdusco, President and CEO of Canada One, commented: "This year's program reflects our commitment to disciplined exploration that will ultimately progress to fully defined drill targets. With multi-year drill permits in place, the Company is well positioned to unlock the full potential of Copper Dome. Its location within the prolific Quesnel Trough Porphyry Belt, and its direct adjacency to Hudbay Mineral Inc.'s operating Copper Mountain mine, further underscores the Project's strategic significance."

Phase 1: Target Refinement and Surface Evaluation

The Phase 1 program, planned for early summer 2026, will focus on detailed surface work to enhance geological understanding and prioritize areas for follow-up exploration. Key activities include:

• Detailed 1:5,000-scale geological and alteration mapping across the Boundary Zone and Friday Creek targets

• Collection of approximately 1,200 soil samples over Friday Creek and Boundary Zone

• Continued prospecting at the Reco and Copper Dome South areas

The objective of Phase 1 is to refine and rank target areas ahead of geophysical surveying. Results will guide the selection of areas of interest ("AOIs") for deeper investigation.

Phase 2: Geophysical Targeting and Drill Definition

Building on Phase 1 results, the Phase 2 program will focus on subsurface characterization and drill target generation. Planned activities include:

• Approximately 20 line-km of induced polarization (IP) surveying over Friday Creek and Boundary Zone AOIs

• Follow-up 1:5,000-scale geological and alteration mapping at Reco and Copper Dome South

• Drone magnetic surveys, contingent on Phase 1 outcomes

This phase is designed to define deeper drill targets, with particular emphasis on identifying chargeability anomalies associated with prospective porphyry systems beneath favorable surface geology and geochemical signatures.

Strategic Approach

The Company's exploration strategy emphasizes a methodical, data-driven approach to porphyry target generation. By integrating geological, geochemical, and geophysical datasets, the program aims to efficiently advance priority targets toward drill readiness while managing exploration risk and capital expenditures.

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 Ag¹. 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.

Copper Dome 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 multi-year drill permit in place, the Company is focused on advancing Copper Dome toward drill-ready target definition.

Quality Assurance / Quality Control (QA/QC)

All rock samples collected from the fall 2025 fieldwork program, were submitted to ALS Geochemistry - Kamloops to be analyzed for Au and PGEs (PGM-ICP24 50 g fire assay), and multi-element geochemistry, including elements Cu, Pb, Zn, Co, and Ag (method ME-MS61).

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 NI43-101 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.
