A former underground Cu-Au-Ag mine located on 47 claims (1922), in the NW¼NW¼ sec. 25, T3S, R14E, about 1 mile W of Dripping Springs and 1 mile NNW of Manhattan Mountain, 1¼ miles E of Troy Ranch and ¼ mile E of the Pinal County line, on BLM-administered land. Produced 1913-1918. The Pinal Development Company and Mr. F.M. Pool were past operators.
Mineralization is a 15 foot thick ore horizon on limestone, hosted in the Mescal Limestone and diabase. Ore control was a diabase-limestone contact with the diabase underlying the limestone; also along small fault fissures. Ore concentration was along the small shear zones with the mineralization associated with a Lower Cretaceous-Tertiary intrusive period. An associated rock unit is rhyodacite.
Area structures include the Late Cretaceous Rattler Granodiorite intrusion, which is 1/8 mile W of the mine. Mineralization and/or fissuring is probably related to this intrusion. The rhyodacite post-dates this intrusion. The downthrown side on most of the fractures in the area is the southern side.
Workings total 762 meters in length and include a main tunnel 1600 feet long, and a depth of 600 feet (Mines Handbook, 1922). The ADMR report (1907) describes various small shafts. There are 220 feet of workings on the Golden Eagle claim, A 150 foot tunnel, and a 43 foot deep shaft in granite.
