A Au-Ag-Cu-Pb-Zn-W, & marble mining district located in T.13-15S., R.26-29E., in the Dos Cabezas Mts.
Mineralization is of several types: 1) Weathered quartz veins containing spotty gold and silver values in Precambrian granitic and schistose rocks; 2) Sporadic base metal sulfides and oxidized products, with occasional scheelite, in irregular fissure veins or in pyrometasomatic zones in complexly folded and faulted Precambrian to Cretaceous formations that have been intruded by Laramide and Tertiary granitic rocks; 3) Marmorized Paleozoic limestones;and 4) Gold placers in alluvial basins or near the mouths of canyons.
Workings include many relatively small, scattered mines, prospects, and placers. Some 4,500 tons or more of ore produced and some $17,000 in gold recovered from placers at irregular intervals from the late 1800's to recent times. There has also been very minor marble production.
