Doré Copper Mining Corp. (TSXV: DCMC) has obtained positive second set of results from its 2022 drilling programme of 45,000 m at its flagship Corner Bay property, located in the Chibougamau mining camp in Québec.
Doré Copper has completed 37 holes totalling 36,135 m.
This drilling programme is part of the feasibility study work to upgrade the Inferred Mineral Resource to the Indicated category. Another infill drilling programme of approximately 2,000 m is planned at Devlin.
Drilling Highlights

- CB-22-90: 6.2 meters of 3.10% Cu and 10.2 g/t Ag, including 2.8 meters of 6.14% Cu, 0.19 g/t Au, and 20.2 g/t Ag
- CB-22-69: 3.4 meters of 2.54% Cu, 0.24 g/t Au, 8.6 g/t Ag, and 1,038 ppm Mo
Main Vein above dyke
- CB-22-84: 3.0 meters of 3.39% Cu, 25.2 g/t Ag, and 419 ppm Mo
- CB-22-89: 4.6 meters of 2.54% Cu, 20.3 g/t Ag, and 346 ppm Mo
“The second set of assay results from the infill drilling program at Corner Bay continue to confirm the continuity of the copper mineralisation,” Ernest Mast, President and CEO of Doré Copper, said.
“In addition, a representative bulk sample of ¼ core is being shipped to a supplier’s facility in the United States for additional ore sorting tests.
“This is to confirm the sorter performance that was reported in the PEA and to produce material for additional communition, flotation and geochemical testwork.”
Corner Bay Drilling Programme
The 2022 drilling programme is designed to infill the Corner Bay deposit at a 50 to 60 meter spacing from surface to a depth of 1,000 m. From the latest results, six holes intersected the Main Vein above the dyke and the remaining eight holes intersected the Main Vein below the dyke, with three holes intersecting the East Vein with lower grade copper mineralisation.
The results are continuing to confirm the continuity of the copper mineralisation for the Main Vein above and below the dyke.
Corner Bay Deposit
In aPreliminary Economic Assessment announced on May 10, 2022, the Mineral Resource estimate (MRE) for Corner Bay contains an Indicated Resource of 2.68 Mt at 2.66% Cu and 0.26 g/t Au containing 157 million pounds of copper and 22,000 ounces of gold and an Inferred Resource of 5.86 Mt at 3.43% Cu and 0.27 g/t Au containing 443 million pounds of copper and 51,000 ounces of gold, based on a cut-off grade of 1.3% Cu and a copper price of US$3.75 per pound.
The Corner Bay deposit contains significant silver and molybdenum which have not been included in the prior MREs. The feasibility study will include the addition of silver and molybdenum as by-products.
The Corner Bay deposit is hosted by the intrusive Lac Doré Complex on the southern flank of the Chibougamau anticline. A regional north-north-eastern diorite dyke also cuts the area. Several significant shear zones oriented north-south and northwest-southeast have been identified in the area. The Corner Bay area is characterized by copper porphyry style mineralisation and by copper mineralisation in shear zones commonly associated with dykes related to the Chibougamau Pluton.
