Arizona Bureau of Mines file data.
A Cu-Au-Ag-Fe-Ba-F-marble mining district located in T.8-9N., R.15-16W., at the South-central edge of the Buckskin Mountains.
Mineralization consists of: (1) Spotty, oxidized, copper mineralization with minor sulfides in Precambrian schist and Mesozoic sediments or as limestone replacements, usually associated with hematite or with quartz, barite, and fluorite along fracture or fault zones; and, (2) Varicolored marble, probably metamorphosed Paleozoic or Mesozoic limestone.
Workings include several small prospects and mines worked intermittently since the early 1900's. Total production would be some 212 tons of ore containing about 4.5 tons of copper, 45 oz. gold, and 35 oz. of silver.
Mineralization is gold
