A former asbestos mine located in sec. 13, T4N, R17E, about 1¾ miles SSW of the highway 60-77 bridge. Phillips gives the location as sec. 35, T5N, R17E. Opened in 1921, reopened 1928-1930 and 1936-1938.
Mineralization is a vein deposit with a linear ore body hosted in the Mescal Limestone. The ore zone is 0.08 meters thick. The asbestos is in 2 zones that are 14½ feet apart. These zones are in a sliver of Mescal Limestone, 35 to 40 feet thick, overlain & underlain by thick diabase sills.
The favorable limestone beds were folded upward in nthe area now outlined by the stope, on intrusion of the underlying diabase sill, and were folded downward adjacent to the dike, which bounds the sliver of Mescal Limestone, on the SE. The resulting structure is dome-like. The area of greatest deformation is now approximately outlined by a stope, on nthe upper asbestos zone. In this area, stresses imposed by the doming swere relieved along numerous small-scale thrust and bedding faults. Asbestos was concentrated where faults are most numerous.
Workings include several hundred feet of drifts (lower zone); raises & 350 feet of drifts (upper zone). Production was some 30 tons of crude fiber (before 1928); 210 tons fiber (1928-1941).
