Kidd Mine is an underground base metal mine in the city of Timmins, Ontario, Canada. It is owned by Glencore Inc., and operated by Kidd Operations, a Glencore subsidiary. The mine was formerly owned by Xstrata Copper, Falconbridge Ltd., and Texas Gulf Sulphur. 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 the majority of the Met Site, concentrate is now shipped to Quebec for processing. Kidd Mine is the world's deepest copper/zinc mine.
