A former underground Au mine on a group of 7 claims located in sec. 33, T9S, R20W, 3 miles NNE of the Fortuna Mine on the crest of the Gila Mountains, on BLM-administered land. Started in early 1931 by Mr. John Miller and owned by him and C.R. Norman.
Here, sharp, rugged peaks rise from 500 to 700 feet above their intervening saddles, or more than 2,000 feet above the adjacent plains. Many of the mountain slopes lie 45ΒΊ from the horizontal, and some of them are nearly vertical. Long, rocky canyons lead down from saddles and outward to the plains.
This portion of the range is made up of gneiss, the lamination of which strikes approximately East-West and dips 60ΒΊ southward. Considerable jointing and minor faulting are apparent. The principal jointing strikes at right angles to the bedding and dips rather steeply eastward, but another strong system dips in the opposite direction. Other joints strike nearly East-West and dip steeply northward. Several pegmatite dikes cut the gneiss and, in places, contain garnet and lodestone.
A prospect hole on the eastern slope showed an 8 inch quartz vein that strikes a few degrees south of east and dips southward. This quartz, which is rather fractured and cellular at the surface, contains abundant iron oxide and a little visible gold. Although the vein pinches and swells, it is traceable for some distance eastward.
A few hundred yards father SW, and on the oposite slope, a horizontal cut into the steep slope exposes a vein that strikes N.20ΒΊW., and dips about 15ΒΊ NE.As exposed, this vein contains more pulverulent iron oxide than quartz and has an irregular width of not more than 1 foot. It appears to follow a fault, and is traceable, with minor interruptions, for about Β½ mile southward. Many fractures and a few minor faults join it, but without effecting any visible displacement. Part of the iron oxide of the vein is red, and much of it is black and sooty, but no manganese is present. The quartz is of even grain, but broken by many fractures that are filmed with iron oxide. In places, thin, fine flakes of gold are abundantly scattered over the fracture surfaces, and a few rounder particles are within the more solid quartz. Pyrite occurs sparsely scattered throughout the quartz. In places, veinlets of iron-stained calcite occur within the quartz. A little sericite occurs in the immediately adjacent wall rocks.
Several hundred yards farther north, a nearly vertical quartz vein, about 1 foot wide, strikes southward. It shows abundant iron oxide and some copper stain.
Workings include a few shallow cuts.
