Located on the Commodore fault system, history of the mine dates back to 1901. Shafts on the property have produced both fluorite and zinc (smithsonite and sphalerite). The Rock shaft is the deepest (240 feet). Between 1924 - 25 between 7,000 and 8,000 tons of smithsonite were removed.
The southern part of the property has the Maddox shaft, sunk in late 1941, early 1942 to remove about 215 tons of "gravel spar" fluorite. A crosscut was made to the Commodore fault and in 1945, a vertical raise was cut (the Yandell shaft). Mud, gouge, calcite, fragments of veins of fluorite and disseminated sphalerite and galena were noted (R. Trace, 1954).
Today the dump of the Rock shaft dominates the area. The open shaft is surrounded by barbed wire and a debris in it, but is NOT capped. Calcite is, by far, the most common mineral found on the dump. All other minerals require some digging in the dump to find.
