An underground Ag-Au-Cu mine.
Workings included a shaft and an apparent auxillary shaft (air shaft ?). This latter working still exists as a fenced shallow verticle opening with an apparent drift at the bottom and is located several hundred feet from the main shaft and dumps.
Field Observations: As of February 3, 2006, the site appears to be substantially reclaimed. The shaft collar is apparent but only a shallow pit remains. Dumps are bulldozed but the remnants are accessible for collecting. Outcrops containing specularite are also accessible.
Blue Cu mineralization forming radial-fibrous structures with "hairy" coatings were collected but remain unidentified.

|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)
