A former small underground Pb-Ag-Zn-Cu-Au-Mo mine located in the center sec. 18, T.18S., R.17E., 10 miles SSW of Pantano. Owned by E.P. Hilton.
Mineralization is pipelike and irregular ore bodies with small pockets of secondary lead, zinc & copper minerals with galena along fissures in Permian limestone in close association with a dioritic intrusive sill or dike. The ore occurs below the diorite. The host rock unit is the Concha Limestone. An associated rock unit is the Sycamore Canyon Quartz Monzonite. Ore control was along joints, fissures and solution cavities adjoining the sill. Alteration was strong oxidation on the 750 (deepest) level, and massive sulfide gossan.
Local structures include fissures, NW tear breaks, and NE dikes.
Workings include a shaft to 228.6 meters deep. There was extensive development but little indication of much production, e.g., no ore bin or truck road. Developed to the 750 level. Worked since the early 1900's to 1930's. Produced some 150 tons of ore averaging about 50% Pb, 10 oz. Ag/T, some Zn and minor Cu & Au.
