A former underground Cu-Ag-Au-Pb-Zn mine located on 28 patented claims N & NE of Jerome and NE of the United Verde Extension Mine. Shaft collar is at 4,749 feet of altitude. Owned by the Jerome Verde Copper Co. (before 1921); and, the Jerome Verde Development Co. (1921- ). Produced 1901-1920.
Mineralization is a pyritic replacement deposit in schist known as the Main Top orebody, hosted in the Deception Rhyolite, quartz porphyry and the Grapevine Gulch Formation. Ore control was stratigraphy and igneous activity. Ore concentration was oxidation at near surface. Alteration included chloritization and sericitization.
Area structures include massive sulfide lenses elongate parallel to bedding in metavolcanic rocks. Foliation in metavolcanic rocks trends N10W to N40W.
The orebody was mined from the underground workings of the United Verde Extension Mine. It was stoped from the 1300 level to the 10th floor (bench) above the 1100 level. It was about 200 feet long and from 10 to 30 feet wide. Workings include the Columbia shaft (1,061 feet deep) that connects with 1,200 feet of workings, mainly on the 1100 foot level. Produced 10,000 tons of ore at 8 to 12% Cu. Total production was 1,500,000 pounds of Cu (Elsing & Heineman (1936, p. 101)).
