“The Corner Bay project boasts one of the highest-grade copper deposits in the Americas.”
Retail and institutional mining investors often hear the same catch phrase no matter what metals sector in which they choose to invest – the best deposits have already been discovered and (in many cases) have already been mined to depletion. The junior exploration companies who locate and develop these ore deposits must look in ever more remote locations, or deeper and deeper into the earth’s crust. But not always. Sometimes, opportunity is closer than it looks.
Doré Copper Mining Corp. (DCMC) (
TSX-V:DCMC,
Forum) is a near-term, near-development exploration company with proven high-grade copper and gold assets in Quebec with district-scale exploration upside. In a recent Stockhouse article, we took a deep dive into how Doré Copper’s excellent land package and existing infrastructure provide the company with a distinct capital intensity advantage.
DCMC acquired the assets as a private group in September 2017 and embarked on a 19-thousand metre drill program at the Corner Bay and Cedar Bay properties. Doré Copper also has 11 past producing mines or deposits with the potential for additional discoveries.
And the company’s most recent assay and drill results from its Corner Bay Drill Program bear noticing.
Highlights to date from 2020 drilling include:
- CB-20-17: 7.0 meters of 9.08% Cu, 0.41 g/t Au and 30.64 g/t Ag, including 4.75 meters of 11.07% Cu, 0.48 g/t Au and 36.11 g/t Ag (TW approx. 4.6 meters)
- CB-20-15: 7.45 meters of 2.38% Cu, 0.12 g/t Au and 4.16 g/t Ag, including 3.65 meters of 3.65% Cu, 0.18 g/t Au and 6.2 g/t Ag (TW approx. 4.8 meters)
- CB-20-12: 2.45 meters of 3.21% Cu, 0.11 g/t Au and 18.8 g/t Ag (TW approx. 1.6 meters)

Corner Bay Property
The Corner Bay project boasts one of the highest-grade copper deposits in the Americas. The project is located approximately 45 kilometres to the south of the Company’s Copper Rand mill deposit and is current being drilled to expand its estimated resources. The Corner Bay project has an indicated resource of 1.35 Mt at average grades of 3.01 percent Cu and 0.29 g/t Au, containing 89.8 Mlb of copper and 13,000 ounces of gold, and an inferred resource of 1.66 Mt at average grades of 3.84 percent Cu and 0.27 g/t Au, containing 140.3 Mlb of copper and 15,000 ounces of gold, assuming a cut-off grade of 1.5 percent Cu and a copper price of US$3.25 per pound.

Figure 2. Long section of the main vein of the Corner Bay deposit indicating areas where the deposit is open. The diorite dyke is vertical and the main vein dips approximately 75 degrees to the west (out of the page). Therefore, the dyke splits the mineralized body with the upper portion to the east of the dyke and the deeper portion to the west. There is mineralization on each side of the dyke at certain levels.

Ernest Mast, Doré Copper’s President and CEO, commented on both the copper and gold findings:
“The results of the drilling program suggest that we’ll be able to expand the mineral resource at Corner Bay, one of the highest-grade copper deposits in the Americas. The deposit remains open in all directions and we have numerous targets that will be tested in the future. In addition, we did a downhole EM survey on a shear structure east of the main vein that will generate additional targets. Drilling has commenced at Cedar Bay to test the high-grade gold mineralization of the parallel 10-20 zones where previous drilling intercepted numerous high-grade intercepts including 2.4 meters of 19.5 g/t gold and 1.67% copper as well as test the main vein at Cedar Bay at depth. After the Cedar Bay program, drilling will commence at the high-grade gold Joe Mann mine to test the downdip potential where previous drilling intercepted 3.02 meters of 30.3 g/t gold.”
Savvy investors with an eye to near and long-term, past-producing properties in mining-friendly jurisdictions know a good thing when they see it. And as the report above details, Doré Copper Mining’s recent drill results are proving better than just good.
