A former Ag-Au occurrence/mine located in the SE¼ sec. 11, T27N, R20W, G&SRM, on private land within a Bureau of Land Management administered area. Discovered 1892. Previous operators included Consolidated Minerals (1968), UTEX Exploration (1962), and Payne and McAllister (1947). Owned by Mrs. J.C. Calhoun - White Hills Mining Company, Texas (1977), and by the Jordan Estate, Rhode Island (1977). Operated by Corval Development Incorporated, Kingman, Arizona (1979-1982). The USGS MRDS database stated accuracy for this locality is 10 meters.
GRAND ARMY OF THE REPUBLIC MINE.
The Grand Army of the Republic mine is located on Grand Army Wash, on open ground about three-fourths of a mile north of Main street. It is extensively developed to a depth of 700 feet, mainly by inclines, drifts, stopes, and shafts distributed on five levels, in part approximately as shown in fig. 22, the inclines being descended by tram tracks, which, together with the hoists, are still in place. Water level is reached at a depth of about 600 feet. The immense dumps indicate that much work has been done.
The country rock is gneissoid granite and schist. It is very highly altered and iron stained. The deposits are contained in two nearly parallel veins, situated about 30 feet apart, the main one being the lower. At the mine the veins strike N. 62° W. and dip. about 23° NE., and the country rock seems to dip with them, but is much disturbed. At a point 150 yards southeast of the mine, however, the dip of the veins increases to about 75°, and farther on, about one fourth of a mile from the mine, the veins appear in the West Treasure shaft, to which openings show that they are continuous from the G. A. E. mine.
In the G. A. E. mine the ore is free-milling, and much of it is very rich, some being said to average 6,000 to 7,000 ounces of silver to the ton. The mine is reported to have produced much rich ore from all its five levels. During a considerable portion of the Eoot-Moffatt regime the main force of the miners worked here, sometimes more than 100 men stoping at once.

Mineralization is a precious metals deposit hosted in Neoproterozoic schist. The ore body strikes N62W and dips 23NE. Two veins are situated 30 feet apart. Schistosity parallels the veins, local shear zones NW to E-W cut across NE schistosity. Local rocks include Early Proterozoic granitic rocks.
Workings include underground openings with a length of 1,066.8 meters and an overall depth of 60.96 meters. The main shaft is a 20 degree incline, 700 feet long. Commencing in 1969, a cyanide leach operation was conducted on the GAR claim and the Hulda claim to the W.
Most production from the 1890's was unrecorded.
