The Lucky Friday mine is an underground silver, lead, and zinc mine in the western United States, near Mullan, Idaho.[2] Operated by Hecla Mining company, it is one of the few mines remaining operational in the Silver Valley of northern Idaho, producing 1000 tons of ore per day. The ore deposit type is Polymetallic veins of hydrothermal origin. The mining method used is underhand cut and fill mining.[3]
The mine's primary access and production are through the Silver Shaft, an 18-foot (5.5 m) diameter, concrete-lined shaft sunk to a depth of 6,200 feet (1,890 m),[4][5][6] over 2,800 feet (855 m) below sea level.
