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.
Welcome Nugget The Welcome Nugget was the name given to a large gold nugget, weighing 2,217 troy ounces 16 pennyweight. (68.98 kg), that was discovered by a group of twenty-two Cornish miners at the Red Hill Mining Company site at Bakery Hill (near the present intersection of Mair and Humffray Street) in Ballarat, Victoria, Australia, on June 9, 1858. It was located in the roof of a tunnel 55 metres (180 feet) underground. Roughly shaped like a horse's head, it measured around 49 cm (18 in) long by 15 cm (6 in) wide and 15 cm (6 in) high, and had a roughly indented surface. It was assayed by William Birkmyre of the Port Phillip Gold Company and given its name by finder Richard Jeffery. Eclipsed by the discovery of the larger Welcome Stranger eleven years later in 1869 (also in Victoria), it remains the second largest gold nugget ever found.
