Kidd Mine

Kidd Mine or Kidd Creek Mine is an underground base metal (copper-zinc-silver) mine 24 km (15 mi) north of Timmins, Ontario, Canada. It is owned and operated by Swiss multinational Glencore Inc. The ore deposit was discovered in 1959 by Texas Gulf Sulfur Company. Exploration drilling at the Kidd site began in November 1963. In 1981, it was sold to Canada Development Corporation, then sold in 1986 to Falconbridge Ltd., which in 2006 was acquired by Xstrata, which in turn merged with Glencore in 2013. Ore from the Kidd Mine is processed into concentrate at the Kidd Metallurgical Site, located 27 km (17 mi) southeast of the mine, which until 2010 also smelted the ore and refined the metal produced. Following the closure of most of the Met Site, concentrate is now shipped to Quebec for processing. Kidd Mine is the world's deepest mine below sea level (2,733 m (8, 967 ft) below sea level) as well as the deepest copper-zinc mine (3,014 m (9, 888 ft) below the surface).
