Teck Resources Limited known as Teck Cominco until late 2008, is a Canadian metals and mining company. Canadas largest diversified resources company, it was formed from the amalgamation of Teck and Cominco in 2001. Cominco started in 1906 as The Consolidated Mining and Smelting Company of Canada, formed by the amalgamation of several units controlled by the Canadian Pacific Railway. CM&S, or "Smelters" as it was often called by investors, changed its name to Cominco in 1966. Comincos core Sullivan Mine in Kimberley, British Columbia which began production of lead, zinc, silver and tin in 1909, would operate for more than 90 years until its ore reserves exhausted in 2001. Teck began as Teck-Hughes Gold Mines Limited in 1913, to develop a gold discovery by prospectors Sandy McIntyre and James Hughes at Kirkland Lake, Ontario. The Teck-Hughes Mine would produce for 50 years until 1965. The Beaverdell Mine, purchased by Teck in 1969, went back even further to 1898, and produced silver until 1991.
