Detailed explanation-1: -Unremediated mines can cause local soil and water contamination, altered hydrology, habitat loss and fragmentation, and biodiversity loss. They can also cause perpetual environmental liabilities, such as acid mine drainage.
Detailed explanation-2: -Canada is rich in mineral resources. The vast Canadian Shield, with its masses of igneous and metamorphic rocks, contains numerous large deposits. Metallic minerals are also found in such rock types in the Western Cordillera and the Appalachians.
Detailed explanation-3: -Many Canadian lakes, rivers and watersheds are already contaminated by mining, some very recently. Dozens of mine waste sites will require wastewater treatment for the next 200 to 400 years, or more.
Detailed explanation-4: -Gold is Canada’s top mineral export and accounts for almost a quarter of the total value of mineral and metals exports.
