A Cu-Mo deposit / prospect located in secs. 8, 9 & 15, T4S, R13E, about 1 mile S of the Gila River and about 3 miles west of Kelvin. Owned by the Riverside Mining Co., A.H. Johnson, Phoenix, President and Manager.

Country rock at the deposit (Ruin [Oracle] Granite and Teacup Granodiorite) is coarse-grained biotite granite that is cut by east- to northeast-trending quartz porphyry and aplite dikes as much as several feet wide. A 40 foot wide shear fault occurs locally. Quartz veins are exposed at the surface and underground, and irregular quartz masses are exposed northeast of the shaft. Southwest of the shaft, a quartz vein ranging from 1 inch to 2 feet in width strikes N.70ºE. and dips 80ºN. Surface exposures are barren except for limonite and faint copper stains. Underground, some of the veins contain pyrite, chalcopyrite, and traces of molybdenite.

Molybdenite occurs as thin seams in the fault gouge of two fault zones that strike east to northeast. Alteration is silicification and seritization.

Workings in 1943 consisted of an 84 foot deep vertical shaft, an 80 foot crosscut extending N.15W. from the bottom of the shaft, and two drifts, 18 and 15 feet long extending west from the crosscut at 18 and 62 feet, respectively, NW of the shaft. In total, there were 8 shafts and diamond drill holes.
