Between Discovery Mine and Big Dan Mine, which mine was named after Dan O'Connor?
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.
