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.
Ruggles Mine Ruggles Mine is an open-pit mine that is no longer in operation and had been turned into a tourist attraction. It is now closed and for sale. The mine is located 40 mi northwest of Concord, New Hampshire, in the town of Grafton, a short distance from Route 4 at the village green. The spacious pit includes tunnels and underground chambers, some of which are filled with water, for exploring. Visitors are allowed to keep any of the various minerals that are to be found on the mine floor or that can be hammered loose from the walls of the pit.
