A former underground Cu-Ag-Au mine located on 20 claims in upper Deception Gulch, about 4,000 feet south of the United Verde Mine, and about 1 mile SW of Jerome. Owned by the Verde Central Mines, Inc.; and then, Phelps Dodge Corp. Closed in 1929.
Mineralization is a vein deposit with a tabular orebody hosted in the Deception Rhyolite, Cleopatrqa Quartz Porphyry and an unknown metabasalt. Ore control was stratigraphy and igneous activity. Ore concentration was oxidation at near surface. Alteration was chloritization and sericitization.
The Verde Central ore zone is along the east margin of the quartz porphyry in contact with the Deception Rhyolite. The contact is irregular and interfingering, and dike offshoots of porphyry cut the rhyolite. The Verde Central was a blind prospect. Two ore bodies were found.
Mineralization is a fault vein with bunches of quartz and local copper staining. The country rock is greenstone with intrusive tongues of quartz porphyry, both more or less schistose and difficult to separate. The vein strikes N.40º-60ºW. and dips 60ºNE. Schistosity strikes N.20ºW. In places there is much disseminated ore through 15 to 20 feet of schist, with copper content of 1 to 3%.
Area structures include foliation in metavolcanic rocks that trends N10W to N40W. Massive sulfide lenses elongate parallel to bedding in metavolcanic rocks.
Workings include a 60º inclined shaft about 800 feet deep on the incline that connects with 4 levels of workings aggregating 2,000 feet. A 1,900 foot deep shaft was ultimately sunk. A long crosscut was driven to the west on the 1450 level.
