A former underground Ag-Cu-Au-Pb-Mn-Zn mine located in secs. 15,22, 23, 26, and 27, T2S, R11E, about 6 miles SW of Superior, and about 5.1 miles NNE of Mineral Mountain, on private land. This mine is a group of seven contiguous patented claims that run N-S along the E edge of secs. 22 and 27 (they are: America, Alaska, Asia, Australia, Africa, Europe, and Great Pacific). Originally a silver mine, later a silver-manganese mine. Located approximately 5 miles SW of Superior. Discovered by John Reymert in 1885. Produced 1887 - 1930 and 1935 - 1960. Owned by Triple Nichol Inc. (1989). The USBM-ABGMT lists as past operators: Reymert Extension Silver Mines Inc. (1946); James Todd; W.J. Falbach; W. Falbach and A. Habstritt (1935); Reymert Mining Co. (1930); Jackson; Diggs; Cooley and Hicks (1927); and Inspiration (1987).
This deposit is comprised of a nearly one mile long (1.8 km) vein outcropping. The vein is nearly vertical. The northern end is briefly hosted in diabase and is approximately 3 meters wide. The host rock abruptly changes to a crenulated muscovite schist (Pinal Schist) for most of the length of the vein. The vein widens to as much as 30 meters, and "feathers" at the southern end. The vein is extensively altered through a hydrothermal process and contains much black, ocherous manganese oxides. Shafts all go to a depth of approximately 400 feet (130 meters) where the vein is principally galena and very narrow. The ore zone cuts schist and is composed of bands of quartz and baryte. The manganiferous calcites and siderite are crystalline and in places widen into lenses. Epithermal silver-manganese vein system. The mineralization is associated with a Tertiary intrusion and volcanism. Quartz latite 15.8-17.4 MY is exposed 0.5 mile S of the mine workings.
NOTE: Subsequent to the cessation of mining operations, the property was used to quarry landscaping stone (Pinal schist) that exposed significant ore. That quarrying operation has resumed (circa late 2002) and the property is strictly off-limits to collectors (unfortunately).
Workings include two main shafts, one on either end of the ore body, The Alaska shaft and another one about 2,000 feet S. Lateral work done includes a few tunnels and a near-surface drift running a significant distance N-S through the ore.
An estimate of ore reserves in 1986 was 426,000 metric tons.

|Early Proterozoic metasedimentary rocks|
Age: Statherian (1600 - 1800 Ma)
Description: Metasedimentary rocks, mostly derived from sandstone and shale, with minor conglomerate and carbonate rock. Includes quartz-rich, mostly nonvolcanic Pinal Schist in southeastern Arizona and variably volcanic-lithic sedimentary rocks in the Yavapai and Tonto Basin supergroups in central Arizona. (1600-1800 Ma)
