A former underground Au-Ag-Cu-Be-Mn mine located in sec. 5, T.21N., R.21W. Davis Dam 7.5 minute topo map), about 2 miles East of the Colorado River in the former Union Pass District. Owned at times, or in part by the New Comstock Mining Co. (1930-1931); and the Katherine Gold Mining Co. (1925-1929). The shaft collar is at 990 feet of altitude.
Mineralization is an epithermal vein of the Comstock type that strikes N.62ºE. and dips about vertically. It is a stringer lode that has a width of more than 60 feet (12 meters) at surface but narrows underground. Vein filling usually consists of a series of closely-spaced stringers in granite. In some places the vein filling was solid quartz and calcite up to 10, or more, feet wide. The mine is on a small knob of granite about 150 feet (45 meters) diameter. Mineralization also includes secondary copper minerals. The concentration process was copper stain, associated with calcocite, and local enrichment due to supergene processes. Host rock includes the Golden Door volcanics and the Times porphyry.
Workings include development to the 300 foot level, a new 900 foot deep shaft. The mine is opened for a 1,700 foot length. Started in 1900 and closed in 1904. Reopened 1915 and closed 1929, with presumed activity in 1930-31. This mine gave its name to the original Katherine District, later the Union Pass District, and now consolidated into the Oatman District.

Age: Cenozoic (0.126 - 3.6 Ma)
Description: Coarse relict alluvial fan deposits that form rounded ridges or flat, isolated surfaces that are moderately to deeply incised by streams. These deposits are generally topographically high and have undergone substantial erosion. Deposits are moderately to strongly consolidated, and commonly contain coarser grained sediment than younger deposits in the same area. (0.75-3 Ma)
