Cole Mine (Cole shaft; Cole No. 3), Bisbee, Warren District, Mule Mts, Cochise Co., Arizona, USA

Latitude & Longitude (WGS84): 31° 25' 5'' North , 109° 54' 24'' West
Latitude & Longitude (decimal): 31.41806,-109.90667

A former large output underground Cu-Ag-Bi mine located in the S½NE¼ sec. 21, T23S, R24E, approximately 1½ miles WNW of Warren, on private land. One of the major Calumet and Arizona Company mines. Owned at times, or in part, by the Lake Superior & Pittsburg Development Co., Calumet & Arizona Mining Co., and the Phelps Dodge Corp.

Mineralization is partially oxidized copper ores in irregular replacement orebodies in relatively unaltered Cambrian Abrigo and Devonian Martin limestones along the Dallas fault zone and adjacent fracture zones.

Local structures include common pre-mineralization faulting and tilting. Main fault directions are N10W to N40E and S30W to N50W.

Workings include a deep shaft. Probably produced several hundred thousand tons of ore; included in Calumet & Arizona and Phelps Dodge totals after 1915.

Regional Geology

This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

Kungurian - Moscovian
272.3 - 315.2 Ma
Permian to Pennsylvanian sedimentary rocks

Age: Paleozoic (272.3 - 315.2 Ma)

Stratigraphic Name: Hermit Formation; Supai Group; Schnebly Hill Formation; Naco Group

Description: Interbedded sandstone, shale, and limestone usually characterized by ledgy outcrops. Orange to reddish sandstone forms cliffs near Sedona. This unit includes Supai Group and Hermit Shale in northern Arizona and Naco Group in southern Arizona. It was deposited in coastal-plain to shallow-marine settings during time of variable and changing sea level. Rocks of this map unit in southern Arizona may be in part equivalent to Permian rocks of map unit P in central and northern Arizona. (280-310 Ma)

Lithology: Major:{sandstone,shale,limestone}
