Carbonate Mine is despite the name not a carbonate mine, it was mined for anglesite and galena. The mine is located far up Bald Mountain, a place which is not reachable by normal cars. Visitors are picked up just north of the town of Breckenridge and brought up to the mine by a 4WD vehicle. That's the reason why the mine is only open during summer and the visit is weather dependent.

Because of the height the tour is pretty impressive, but requires some care. The mine temperature is below zero, which explains the ice formations inside. Warm clothes and appropriate shoes are essential, the guides will not take visitors without closed shoes into the mine. Helmets, miners lamps or torches, and rain jackets are provided. The ice forms huge crystals, which are very fragile. As they are pure white, they are probably the reason for the name, as they resemble calcite (carbonate) crystals.
