A former small surface Mn-Cu-Ag mine located in the NE¼SW¼NW¼ sec. 21, T.23S., R.24E., on the SW slope of Escabrosa Ridge, ¼ mile NE of the Whitetail Deer Mine and about 1½ miles west of Warren, on private land. Produced 1918-1921. Owned by the Phelps Dodge Corp.
Mineralization is ore along a nearly north-south fissure zone, which here traverses the upper part of the Escabrosa Limestone and irregular prongs of replacement ore extend into the limestone on each side of the ore zone. Some follow bedding planes, and others cut across the beds. The ore body is 60.96 meters long and 4.57 meters wide, strikes N25E and dips at more than 80 degrees. Ore is hard manganese oxides in irregular pods and plugs along a fracture and breccia zone in Mississippian Escabrosa Limestone. An associated rock unit is the Sacramento Hill Stock. The deposit runs northward into the Summit claim of the Calumet and Arizona Mining Co.
Local structures include common pre-mineralization tilting and faulting.
Workings include a cut about 15 feet wide, 125 feet long, and 45 feet high at the face (1930). Near the face, an underhand stope extended northward along the zone an extra 50 to 60 feet the stope reached a maximum depth of 20 feet or more below the open cut floor. Produced more than 1,500 tons of ore. Maximum of 0.5 oz. Ag/T.
