A Au-Ag-Pb-Cu-Zn-W (Ba-V) mining area located in T.14-17S., R.4-6E. (partly protracted), South Comobabi Mountains.

Mineralization is auriferous and argentiferous quartz, quartz-calcite, or dolomite, and quartz-barite veins with partly oxidized, spotty base metal sulfides and local tungsten minerals along faults and fracture zones in a thick series of Cretaceous (?) andesite flows invaded by Laramide granitic to dioritic intrusions, and in the intrusives. The southern Comobabi Mountains is a faulted complex of steeply-dipping sedimentary beds together with abundant dikes and stocks of dioritic to basic porphyrys. The sedimentary rocks are largely massive, impure shales which strongly resemble certain Cretaceous formations of southern Arizona.

Workings include numerous, scattered, small mines and prospects, mostly relatively shallow. Worked sporadically from at least the early 1700's to recent times. Total production is estimated and recorded as some 6,500 tons of ore containing about 3,500 oz. Au, 102,000 oz. Ag, 92 tons Cu, 182 tons Pb, 2 tons Zn, and a small amount of tungsten concentrates.
