A former surface and underground Cu-Au-Ag-Mo-Pb-V-Fluorspar mine located in the SE¼NW¼ sec. 32, T10N, R10E, at the head of Oxbow Gulch, about 1 mile E of Moore Mountain, about 0.8 miles W of the top of Oxbow Hill, and about 1½ miles SSW of Oxbow Estates, 7 miles S of Payson, on National Forest land. The property consists of 18 claims, (2 patented: the Oxbow and Golden Wreath). Discovered by Al Sieber, William Moore and St. John in 1875. Produced 1916-1936. Previous owners and operators include: the Atlantis Mining Company (1917); J.P. Walker; W.E. McCules; A.M. Packard; P.J., C.W. and P.H. Harrison; and Alva Buckley (1941). Owned by Mr. Pete Saccuci (1973). Operated by Mr. Clay Thorne (1980).
Mineralization is a vein of considerable with with a linear shaped ore body hosted in Payson Diorite. The ore zone is 609.6 meters long, 1.83 meters wide, 160.93 meters thick, strikes N-S and dips 45-85W. The fissure vein runs N-S for much of its length but turns toward the east at its northern and southern ends. The vein shows 5 ore shoots, and numerous cross veinlets. There are also placer deposits on the property. Vein widths vary from 18 inches to 6 feet. Orange-yellow scales on a fracture plane associated with cuprodescloizite. Ore control was the curving fissure (Oxbow-shaped fault fissure) zone, NE-trending dikes, intrusions and faulting. Associated rock units include rhyolite and granite.
Area structures include Tertiary sediments approximately 1 mile south of the mine. The local diorite has a uniform texture, is coarse-grained, and is cut by a complex set of dikes and fault fissures. (See Conway's thesis (1976) for the regional geology).
Workings include a 528 foot tunnel cutting the vein along its full length, a two-compartment shaft down 200 feet, with 40 feet of drifts, and a 40 foot tunnel. The main tunnel contains 3 raises connecting it to the surface and 3 winzes of 110, 45 and 145 feet. There are also numerous pits and trenches on the surface.
14 valid minerals.
