What kind of mines are the Giant Mine and the Discovery Mine?
Discovery Mine The Discovery Mine was a gold mine 81 kilometers northeast (approx bearing of 15 degrees) of Yellowknife, Northwest Territories that operated between 1950 and 1969. Gold was discovered here by Alfred Giauque in 1944. A complete townsite, on Giauque Lake, was established by the company to house workers and their families. The mine produced one million troy ounces (31,000 kg) of gold from one million tons of ore. The abandoned townsite, not accessible by road, was demolished in 2005.
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.
