A Pb-Ag-Cu-Zn-Au mine located in T.20S., R.14E. Owned at times, or in part, by the Calabasas Copper Co.; Boykin; Amado Mines; and, McIntosh.

Mineralization is largely oxidized sulfides in an irregular replacement body in a large, exotic paleozoic limestone block engulfed in Cretaceous dacitic volcanic breccia, and also as spotty mineralization in a quartz-fissure vein cutting the dacite volcanics.

Worked sporadically from the early 1900's through 1949. The group produced some 1,000 tons of ore averaging about 22% Pb, 3% Cu, 3 oz. Ag/T and minor Zn and Au.
