A former Au-Ag-fluorapar occurrence/mine located in the NE¼ sec. 6, T19N, R20W, G&SRM, 3 miles NW of Oatman, on private (patented) land within a Bureau of Land Management administered area. Owned by the Navy Group Mining and Milling Company, California (1926). The USGS MRDS database stated accuracy for this locality is 500 meters.
NAVY GROUP MINE.
The Navy Group mine (see P1..X) is about 1½ miles west of the Miller mine, on the east slope of a north spur of the Hardy Mountains, at about 2,300 feet elevation. This also is on the Hardy vein in the granite porphyry and micropegmatite.
It was located by R. E. Zuver, of Gold Road, by whom and his associate, Maj. R. J. Holmes, it was formerly owned. It is now owned by the Navy Group Mining Company, of Los Angeles. The croppings all the way up the mountain slope, several hundred feet in extent, are strong and are reported to continue so for a mile or more westward to the locality where the mountains fall off into the mesa country on the west.
The mine is developed principally by an adit drift 900 feet in length trending N. 82° W. At 500 feet in from the mouth of the drift the vein is cut off by a north-northwest fault, which should be worked out with care before deep and expensive workings are undertaken. Some seemingly useless work has been done, including 400 feet of drifting, on the projected course of the vein beyond the fault.
The principal part of the vein is from 2 to 4 feet in width and consists principally of quartz with bunches of white and gray crystalline calcite and green and red fluorspar. The ore contains principally gold with a very little silver. It is reported to range in value from $8 to $30 a ton, the best grade being associated with iron-stained quartz.

Mineralization is a vein deposit hosted in trachyte and andesite. The ore body strikes N80W and dips 75N, at a width of 1.22 meters and a length of 1,609.3 meters. A N-W fault cuts off the vein 500 feet from the mine adit. Associated rocks include Pliocene granite. Local rocks include Middle Miocene to Oligocene granitic rocks.
Regional geologic structures include a NNW to WNW-trending vein and fault system in Tertiary volcanic rocks.
Workings include unspecified underground openings with a length of 274.32 meters.
Analytical data results: $8 to $30 per ton.
