The Kidd Creek copper-zinc-silver deposit is located in Timmins, Ontario.

Xstrata Copper and its predecessors have been mining the Kidd Creek copper/zinc deposits since 1965.

The Kidd Mine is focused on developing and sustaining economic mining plans for the Kidd Creek ore body, which is currently mined through two separate shafts known as No. 2 and No. 4.

In December 2011 Xstrata Copper announced the completion of a US$111 million extension to the Kidd Mine. The extension to the mining zone at Mine D to 9,600 feet will extend operations by at least two years to the first half of 2018.

The No. 4 shaft extends to 9,889 feet (3,015 metres) below surface and with the completion of the Mine D project, the Kidd mine is the deepest mine below sea level in the world.
