The Lake Superior region is fertile ground for mining, particularly along the North shore of Lake Superior—home to the metamorphosed greenstone belts of the Wawa subprovince of the great Canadian Shield. Greenstone belts are known to contain high grade gold, silver, copper, zinc and lead ores.
A young Perth, Australlia based exploration company, Superior Lake Resources Limited, is looking at redeveloping two former copper-zinc mines in this region: Pick Lake and Winston Lake. This project is in the very early stages of development. Superior Lake Resources Ltd has contracted Thunder bay based Nordmin Engineering Ltd as the consultant for the re-development strategy. Nordmin is expected to provide a full report by August 2018 outlining cost estimates for mine de-watering, re-equipment, installation of a new mill and other infrastructure, and a schedule of permitting and licensing requirements for development and start-up of mine operations.

Zinc is a metallic element that is prized for it’s anti-corrosive properties; it is used to coat steel and galvanize iron. It is in high demand for use in building materials and electronics. At the Pick Lake and Winston Lake mines, zinc occurs as a Zinc-sulfide (ZnS); as a result the mine has the potential of releasing high levels of sulfuric acid into water systems and the environment. Time will tell whether a federal environmental assessment will be triggered and whether or not Superior Lake Resources Ltd will voluntarily undergo a provincial Environmental Assessment.
