The early stage study outlines a mine life of 10.7 years producing a total of 600.2 million lb. of payable zinc, 230.1 million lb. payable lead, 78.3 million lb. payable copper, 8.1 million oz. payable silver and 38,324 oz. gold at all-in sustaining costs of $0.38 per lb. zinc.
The carbonate replacement deposit was intermittently mined for high-grade silver, gold, lead, zinc and copper sulphides until 1985, when the mine closed leaving faces in massive sulphide.
