Golden Gate claim
A former medium-production surface Mn-Cu mine located in the NE¼NW¼ sec. 16, T.23S., R.24E, about 0.5 mile (ca. 805 m) SW of the center of Bisbee, on a spur of Escabrosa Ridge, just West of Queen Hill, 700 feet (ca. 213 m) WSW of the summit of Queen Hill. Discovered 1918. Owned by the Phelps Dodge Corp.
Mineralization is an irregular lode along a fissure zone that strikes N80ºW and dips 80ºN. The country rock is apparently Naco Limestone, but the deposit is close to the rather indefinite boundary between the Naco and Escabrosa Limestones, and may be partly in the Escabrosa. Ore is mostly hard manganese oxides with copper staining along the fracture zone cutting upper Mississippian Escabrosa or lower Pennsylvanian-Permian Naco Group limestone. The average lode width is 5 feet (1.52 m). The ore is partly as filling in fissures & partly as replacement deposit after limestone. Ore control was proximity to dikes and sills and faulting with associated brecciation. Ore concentration was bornite replacing pyrite. Alteration was gossan with Mn and Fe oxides induced by hydrothermal metamorphism.
Local structures include pre-mineralization faulting and tilting. The main fault directions ate N10W to N40E and S30W to N50W.
Workings include shallow open cuts. Some 800 to 900 tons of manganese ore were produced during WWI.
