Located in central Ontario, Canada, Kidd Creek’s copper-zinc mine is a large open-pit and underground co-production of large polymetallic mines run by the Ecstall Mining Company. The deposit was discovered by Texasgulf Company in 1964. At the end of 1966, the open-pit mine was put into operation. In February 1967 it reached the design capacity of 10,000 t / d. It produced 3.62 million tons in 1972 and began to gradually migrate to underground mining in 1973 and open-pit mining in 1976 All over. Underground mine design capacity of 14,000 tons / day, the use of shaft - ramps open up. 92% of the ore is segmented empty
