What kind of mines are the Giant Mine and the Discovery Mine?
Giant Mine The Giant Mine was a gold mine located on the Ingraham Trail, 5 km north of Yellowknife, Northwest Territories. Giant Mine is within the Kam Group, which is part of the Yellowknife greenstone belt. Gold was discovered on the property and mineral claims staked in 1935 by Johnny Baker, but the true extent of the gold deposits were not known until 1944 when a massive gold-bearing shear zone was uncovered beneath the drift-filled Baker Creek Valley.
Tia Maria mine The Tia Maria mine is a large copper mine located in the south of Peru in the province of Islay, Arequipa Region. The Tia Maria mine, with one of the largest global copper reserves, contains an estimated 641 million tonnes of ore graded at 0.39% copper. The project is operated by Southern Copper Corporation with Newmont Mining Corporation owning a share.
