A zinc-copper-iron mine owned by the Hudson Bay Mining and Smelting Co. Workings are at least 2,100 feet deep.

The Stall Lake Copper Mine produced copper from 1964 to 1994 on a Volcanogenic Massive Sulphide (VMS) hosted in the Anderson meta-rhyolite. It is one of three mined-out Cu-rich deposits (Anderson, Stall and Rod) that originally contained a total of 11.0 Mt with an average grade of 4.27% Cu, 0.56% Zn and 1.5g/t Au.

In the footwall stratigraphy to the VMS deposits, alteration zones represent seawater-related hydrothermal alteration, that like the rest of these rocks are metamorphosed to the amphibolite facies. These zones are cut by a number of discordant, aluminosilicate-rich alteration zones that can be spatially related to overlying VMS deposits
