The Nook Bay deposit incorporates an indicated useful resource of two.7 million tonnes grading 2.68% copper and 0.26 g/t gold and an inferred useful resource of 4.5 million tonnes at 3.2% copper and 0.27 g/t gold. The deposit incorporates 157 million lb. of copper within the indicated class and 320 million lb. of copper within the inferred class.
The corporate says the elevated measurement of the useful resource estimate is a step-change for the financial potential of underground mining. There’s already ramp entry to the Nook Bay deposit and a couple of km of improvement on three ranges. The mine would even be inside trucking distance of the two,700 t/d Copper Rand mill which Doré Copper owns in Chibougamau.
The corporate additionally believes there’s important exploration potential to proceed rising the useful resource. Ongoing drilling has linked the Fundamental vein and Decrease Deep vein under the dyke. The deposit stays open down plunge under a vertical depth of 1,100 metres, and there are untested subparallel zones.
“Our subsequent precedence is the completion of the PEA research for the re-development plan of a hub-and-spoke operation mannequin with Nook Bay as the primary feed to our centralized mill, supplemented by the Devlin and Joe Mann deposits,” stated president and CEO Ernest Mast. “The plan is to proceed exploration drilling from floor at Nook Bay and start infill drilling in 2022 for a feasibility research anticipated in early 2023.”
Doré Copper has awarded the contract to steer the preliminary financial evaluation to BBA Inc.
