Primarily a copper and lead mine (with secondary silver and gold production) located in sec. 5, T. 18 S., R. 12 W. about three 3/4 mile southeast of Vanadium post office and about 2 miles southwest of Santa Rita (Lasky, 1930).

The mine contains a large and well-exposed Zn-Pb-Cu-Ag skarn deposit. The skarn is formed in Carboniferous limestones spatially associated with a nearly vertical swarm of Early Tertiary granodiorite porphyry dikes (Meinert, 1987).

The mine has been operated since about 1900.
