The following lists of mines in Canada are subsidiaries to the list of mines article and lists working, defunct and future mines in the country and is organised by the primary mineral output and province.
The Mountain Pass deposit is in a 1.4 billion-year-old Precambrian carbonatite intruded into gneiss. It contains 8% to 12% rare-earth oxides, mostly contained in the mineral bastnäsite. [5] Gangue minerals include calcite, barite, and dolomite. It is regarded as a world-class rare-earth mineral deposit. [3]
The Ring of Fire is a vast, mineral-rich region located in the remote James Bay Lowlands of Northern Ontario, Canada. [1] Spanning approximately 5,000 square kilometres (1,900 sq mi), the area is rich in chromite, nickel, copper, platinum group elements, gold, zinc, and other valuable minerals.
Canada's mineral resources are diverse and extensive. Across the Canadian Shield and in the north there are large iron, nickel , zinc , copper, gold, lead, molybdenum , and uranium reserves. Large diamond concentrations have been recently developed in the Arctic, making Canada one of the world's largest producers.

Most of the water in the lake evaporates over the summer, revealing colourful mineral deposits. Large "spots" on the lake appear and are coloured according to the mineral composition and seasonal amount of precipitation. [3] Magnesium sulfate, which crystallizes in the summer, is a major contributor to spot colour.
