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.

1600 - 1800 Ma
|Early Proterozoic metavolcanic rocks|
Age: Statherian (1600 - 1800 Ma)
Description: Weakly to strongly metamorphosed volcanic rocks. Protoliths include basalt, andesite, dacite, and rhyolite deposited as lava or tuff, related sedimentary rock, and shallow intrusive rock. These rocks, widely exposed in several belts in central Arizona, include metavolcanic rocks in the Yavapai and Tonto Basin supergroups. (1650 to 1800 Ma)

1600 - 2500 Ma
|Altered rhyolitic tuff|
Age: Proterozoic (1600 - 2500 Ma)
Description: Chlorite-rich crystal tuff of Cleopatra Formation south of Jerome in zone 6B. Similar pattern of chemical alteration as in altered rhyolite. Also includes muscovite- and quartz-rich rocks derived from tuff and crystal-rich rhyolite tuff. Crops out as elongate to circular areas zoned from muscovite-rich margins to quartz-rich core. Exposed east and southeast of Townsend Butte
Comments: Early Proterozoic plutonic rocks are widely exposed throughout map area. In order to aid in the discussion of these rocks, the exposures of plutonic and metavolcanic rocks are divided into six zones (zones 1–6, from west to east). These zones are roughly parallel to regional foliation and contain rock units that are similar to one another. The zones are not crustal blocks nor are they necessarily separated from one another by discrete tectonic structures
