Where to Find Silver, Lead, Zinc Deposits Canada

Lead and Zinc. Lead and zinc ores are found so often mixed that they are described together. In addition to galena and zinc blende, pyrite is generally present and often in considerable quantities, and copper pyrites is generally present. By weathering, the latter may leave green and blue stains. The ore deposits are of two principal kinds:
