A Au-Ag mine located 25 miles NW of Chloride in the foothills of the eastern base of the Black Mountains.
Mineralization is a nearly flat vein in a local sheet of flat-lying dike of altered and pressed minette. The vein is about 6 feet thick and consists of red and green quartz and breccia.
Workings include 12 or 15 shafts ranging from 25 to 60 feet deep and about 500 feet of drifts.
3 valid minerals.

|Tortonian - Bartonian|
7.246 - 41.3 Ma
|Middle Miocene to Oligocene volcanic rocks|
Age: Cenozoic (7.246 - 41.3 Ma)
Description: Lava, tuff, fine-grained intrusive rock, and diverse pyroclastic rocks. These compositionally variable volcanic rocks include basalt, andesite, dacite, and rhyolite. Thick felsic volcanic sequences form prominent cliffs and range fronts in the Black (Mohave County), Superstition, Kofa, Eagletail, Galiuro, and Chiricahua Mountains. This unit includes regionally extensive ash-flow tuffs, such as the Peach Springs tuff of northwestern Arizona and the Apache Leap tuff east of Phoenix. Most volcanic rocks are 20-30 Ma in southeastern Arizona and 15 to 25 Ma in central and western Arizona, but this unit includes some late Eocene rocks near the New Mexico border in east-central Arizona. (11-38 Ma)
