This is a Cu-Pb-Zn-Ag-Au-W mining area located in T15-17S, R29-31E, northern part of the Chiricahua Mountains, in the Galeyville area. The district was started before 1870. Total output has been 152,000 ounces of silver and 100 ounces of gold.

Base metal deposits comprised of sulfides, oxides and carbonates occur along strong silicified fault zones, in replacement pipes and lenses along quartz dikes, and in disseminated deposits in strongly folded, faulted, and often pyrometamorphosed Paleozoic limestone and Cretaceous sedimentary and volcanic formations that have been invaded by Laramide or Tertiary intrusives. Also, spotty scheelite mineralization in pyrometamorphosed Paleozoic limestones.
