“Copper is furnished by British Columbia, Ontario, and Quebec, and its production in the first-named province is rapidly expanding. Lead is almost entirely derived from the mines of British Columbia, but it also occurs in the other provinces. Zinc is widely distributed, but the production is as yet light and mostly from the lead mines of British Columbia. Nickel is largely confined to the mines of the Sudbury district in Ontario—mines that are, however, by far the most important in the world. A certain amount is produced in the Cobalt district, while prospects still farther north, resembling the Sudbury occurrences, are undergoing development. Manganese, in the form of its oxides, is produced intermittently in Nova Scotia and New Brunswick. Mercury has been furnished in small quantity by British Columbia. “Platinum occurs in some gold placer deposits in British Columbia, and also in the nickel-copper ores of Sudbury. Tin and wolfram have recently been found in the gold veins of Nova Scotia. Wolfram also occurs in British Columbia and New Brunswick. Tin-bearing minerals have been discovered in some pegmatites of Eastern Ontario and Quebec. Arsenic is obtained in connection with gold ores in Eastern Ontario and in the silver ores of Cobalt. Antimony is produced to some extent in Nova Scotia. It is being developed in New Brunswick and at a few points in British Columbia. Chromite is mined in Quebec. “Asbestos is the chief mining product of Quebec, and the deposits of this mineral in that province are the most important in the world. Graphite occurs in important deposits in Eastern Ontario and Quebec, but the industry is not fully developed. Gypsum is extensively mined in Nova Scotia and New Brunswick. It is also mined in Ontario. It occurs in other provinces as well, and is beginning to attract attention in British Columbia. Mica is an important product of Ontario and Quebec, where it occurs in shoots in veins. Some of the deposits are very large. Phosphate of lime, or apatite, is still produced, generally as a by-product of the mica mines. Corundum is found extensively in Eastern Ontario from deposits which, as regards purity and magnitude, are unique. Feldspar occurs in wonderful purity in Eastern Ontario and Quebec, and is of considerable industrial importance. Pyrites is now mined extensively in Ontario and to some extent in Quebec. “Petroleum and natural gas are obtained in Ontario. Alberta is also yielding a large quantity of gas, and will probably develop petroleum fields. Gas and some oil are now being produced in New Brunswick. Salt of a very excellent quality is obtained in Ontario. New Brunswick and Manitoba also furnish a certain amount. Magnesite occurs in Quebec, and hydro-magnesite in British Columbia. Structural materials and clay products are found throughout the country, and their production is rapidly growing.”
