A mine on a group of 2 manganese claims located on the NE slope of Black Butte, about 20 air miles S.70ºW. from Wickenburg. Located March, 1918 & owned by J.C. Reed and Simon Rodriguez.
Black Butte is an isolated hill in a detrital plain. The deposit is at an altitude of 2,950 feet, about 600 feet below the summit of the butte and 700 feet above the surrounding plain.
Black Butte is composed entirely of volcanic rocks. Near its base and extending within a few hundred feet of the summit are thick-bedded white rhyolite tuffs and pink flow-banded rhyolite, some of which are glassy or felsitic. The rocks that overlie the rhyolite and extend to the summit are black basalt and probably some andesite.
The deposit consists of small seams of manganese oxides in a shear zone in rhyolite which strikes apparently N.30ºE. The seams are widely distributed through a distance of 20 feet, and they range from a fraction of an inch to 3 inches (7.5 cm) in width. The manganese oxides are soft, black, fine-grained crystals that are probably pyrolusite. They occur for the most part as fissure fillings, but they also replace the wall rocks and included fragments of tuff in the veins.
Workings include a shallow discovery hole.
