Doré Copper Mining Corp. (TSX-V:DCMC, OTCQX:DRCMF) has announced the second set of results from the 2022 drilling program of 45,000 meters at its flagship Corner Bay property, located in the Chibougamau mining camp, approximately 40 kilometers by road from Chibougamau, Quebec.
As of August 10, 2022, Doré Copper said it has completed 37 holes totaling 36,135 meters and was reporting the assay results from 14 holes.
In a statement, Ernest Mast, president and CEO of Doré Copper, commented: "The second set of assay results from the infill drilling program at Corner Bay continue to confirm the continuity of the copper mineralization. In addition, a representative bulk sample of one-fourth 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," he added.

The drilling program is part of the feasibility study work to upgrade the Inferred Mineral Resource to the Indicated category. Another infill drilling program of approximately 2,000 meters is planned at Devlin.
Drilling Highlights:
Main Vein below dyke
- CB-22-71: 6.7 meters of 5.41% copper (Cu), 0.45 grams per ton (g/t) gold (Au), and 29.7 g/t silver (Ag), including 1.6 meters of 12.14% Cu, 0.10 g/t Au, and 67.6 g/t Ag
- 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 parts per million (ppm) molybdenum (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 2022 drilling program is designed to infill the Corner Bay deposit at a 50 meter to 60 meter spacing from surface to a depth of 1,000 meters. 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 mineralization.
The company said the results are continuing to confirm the continuity of the copper mineralization for the Main Vein above and below the dyke.
In the Preliminary Economic Assessment (PEA) announced on May 10, 2022, the Mineral Resource estimate (MRE) for Corner Bay contains an Indicated Resource of 2.68 million tonnes (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-northeastern 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 mineralization and by copper mineralization in shear zones commonly associated with dykes related to the Chibougamau Pluton.
The company is using Miikan Drilling as the drilling contractor. Miikan is a joint venture between Chibougamau Diamond Drilling Ltd., the First Nations community of Ouje-Bougoumou and the First Nations community of Mistissini both located in the Eeyou Istchee territory.
Doré Copper Mining aims to be the next copper producer in Quebec with an initial production target of over 50 million lbs of copper equivalent annually by implementing a hub-and-spoke operation model with multiple high-grade copper-gold assets feeding its centralized Copper Rand mill.
The company delivered its PEA in May 2022 and plans to commence a feasibility study and submit the Preliminary Information Statement of the Environmental and Social Impact Assessment (ESIA) in Q3 2022.
The company has consolidated a large land package in the prolific Lac Doré/Chibougamau and Joe Mann mining camps that has produced 1.6 billion pounds of copper and 4.4 million ounces of gold. The land package includes 13 former producing mines, deposits and resource target areas within a 60-kilometre radius of the company's Copper Rand Mill.
