Peter Berdusco, President and CEO of the Company commented: “As we advance our systematic work at Copper Dome, the Reco, St. Louis, and Elk No.1 mineral occurrences within the Haul Road Zone outline a cohesive mineralized corridor along the Copper Mountain intrusive contact. Our strategy is to progress the highest-confidence areas through focused mapping, sampling, and geophysics, tightening the geologic model while maintaining disciplined capital allocation.”
Haul Road Zone Summary
The Haul Road Zone is located in the central portion of the Property, approximately 1 km east of the Similkameen River and just 1.5 km south of the Copper Mountain Mine’s southern boundary. This strategic location places the zone directly along the same intrusive-volcanic contact that has proven highly productive at Copper Mountain (See Figure 1: “Location Map of the Copper Dome Project“).
Five historical mineral occurrences have been identified in this area – the Reco Prospect, St. Louis Prospect, Johnston Showing, Enterprise Showing, and Elk No.1 Showing, outlining a cohesive mineralized corridor with strong potential for copper-gold systems.
Recent sampling work has confirmed the presence of significant mineralization, particularly around the Reco Prospect, where eleven rock samples were collected within 150 m of the historical Adit. These samples, largely composed of massive pyrrhotite, pyrite, and chalcopyrite (See Figure 2: “Map of Haul Road Zone with Historical Rock Sample Locations and Results (Cu)“).
The combination of high-grade gold values, consistent copper mineralization, and the presence of molybdenum credits highlights the Haul Road Zone as an emerging exploration focus within Copper Dome. With multiple mineralized showings distributed across the corridor and its proximity to existing mine infrastructure, the zone offers a compelling opportunity to expand on historical work and define new copper-gold targets for future drilling.
Mineral Occurrences of the Haul Road Zone:
Reco Prospect
The Reco Prospect is cut by a sulphidic calcite vein within a 2-3 m shear zone striking 005° -040° and dipping 80° northwest. The vein, traced on surface for 120 m and 0.1-1.8 m wide, hosts lenses and pods of massive sulphides (pyrrhotite, pyrite, minor chalcopyrite). A 0.5 m chip sample across a pyrrhotite lens assayed 0.89% Cu, 4.8 g/t Au, and 1.9 g/t Ag1, while a 1 m chip sample at the north end assayed 0.40% Cu, 0.88 g/t Au, and 2.9 g/t Ag (1, p.18). Historical sampling from the 1940s reported up to 17 g/t Au (1, p.18).
The vein is cut by a second less continuous quartz carbonate vein, 0.25 m wide. This structure is hosted in a 2.5-m-wide shear zone striking north and dipping steeply west. The vein is mineralized with stringers of pyrite and traces of chalcopyrite. A sample from this vein assayed 1.3% Cu and 4.98 g/t Au (1, p.18). Exploration began in 1907, when a 167 m tunnel was driven beneath the outcrops (1907-1909). Subsequent operators conducted geological, geochemical, and geophysical surveys between 1968 and 1990.
In 2023, 11 rock samples were taken within 150 m of the Reco showing. Most of these samples were taken from the Adit dump and consisted of massive pyrrhotite with pyrite and chalcopyrite. The samples contained mainly copper and gold mineralization with values in copper for 10 of the samples varying from 0.14% to 1.93%, and with values in gold for 7 of the samples varying from 0.14 to 93.3 g/t (1, p. 24).
St. Louis Prospect
The St. Louis Prospect is hosted in volcanic breccia, siltstone, and sandstone with minor andesitic and cherty tuff of the Nicola Group. The Copper Mountain stock lies 120-250 m north. Mineralization forms a 200-300 m wide pyrite-pyrrhotite zone extending 600 m east from the Reco Prospect, with >1% sulphides as disseminations and fracture fillings (1, p.16).
The western portion of the prospect contains up to 10% pyrite in fractures, shears, and mafic breccia fragments. Eleven historical grab and chip samples assayed 0.003-0.039% Cu and 0.1-0.4 g/t Ag (1, p.17). The prospect was first assessed by Newmont Mining Corp. in 1970-71.
Johnston Showing
Rock sampling within the Johnston showing was taken in 2023 and consisted of two rock samples with both being altered diorite and mineralized with malachite, chalcopyrite, and bornite. The assay returns were 2.7% Cu 0.33 g/t Au for the one sample and 0.71% Cu for the other sample (1, p.25).
Backpack drilling was also done at this location. The rock encountered along one 8-foot (2.4-m) intersection was an altered microdiorite with malachite and azurite. The assay returns varied from 0.1% Cu-0.39% Cu for the four two-foot (0.6-m) sections (1, p.25).
Enterprise Showing
Mineralization occurs within a 70-80 m-wide volcanic embayment (formerly Wolf Creek Fm.) projecting ~70 m NW into diorite of the Copper Mountain stock (Copper Mountain Intrusions). Volcanics show pervasive to stringer biotite-carbonate alteration with albitization. Chalcopyrite is disseminated and along hairline fractures; pyrite is present in trace amounts where Cu is stronger. A 10-m chip sample from a trench analysed 0.11% Cu, 0.038 g/t Au and 0.4 g/t Ag (1, p.18).
In 2023, two samples were taken at the showing with both described as being an altered diorite and/or microdiorite mineralized with malachite, chalcopyrite, and/or bornite. One sample assayed 0.8% Cu and 0.18 g/t Au while the other sample assayed 0.74% Cu and 0.27 g/t Au (1, p.25).
Elk No.1 Showing
In diorite of the Copper Mountain stock, ~80 m north of the Nicola Group contact, a 30 × 60 m area hosts discontinuous K-feldspar (orthoclase) veinlets up to 12 m long and 8 cm wide, at low density (~1 veinlet/4.6 m). Wider veinlets include smoky quartz. Mineralization: malachite and bornite; analogous to the stock’s common “red potash feldspar pegmatite” veins carrying bornite and chalcopyrite. Mapped by Newmont (1970-71) (1, p.19).

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 (TSX: HBM) producing Copper Mountain Mine to the north which hosts Proven and Probable Reserves of 702 million tonnes grading 0.24% Cu, 0.09 g/t Au, and 0.72 g/t Ag. 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 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.
