A former underground Zn-Pb-Cu-Ag-Au mine located on one patented claim 1½ miles south of Bagdad. Located January 1, 1881 by William Waters. Relocated on March 28, 1891 by Fred Maroney and John Lawler and patented by them May 1, 1893. Arizona Hillside Development Co. obtained an option on the claim and acquired surrounding claims (circa 1917). World Exploration Co. obtained control in 1925- 1927. Ownership reverted to John Lawler's heirs, M.L. Lynch & J.W. Lawler. Valerio Rossi leased it during WWII. Goodwin Mining Co. purchased it in 1948. Owned by E.A. Scholz & J.H. Cazier (1950 - circa 1955). Produced 1917-1957.
One of two known examples of massive-sulfide replacement deposits in the Bagdad area. The sulfides have replaced rocks of the Bridle formation near a mass of King Peak rhyolite.
The ore is localized in a unit of tuffaceous sedimentary rock near massive lavas of the Bridle formation. The ore appears as massive-sulfide lenses from 2 to 10 feet (60 cm to 9 meters) wide, and from 10 to 120 feet long, and as much as 100 feet deep, and lies in a broad northeast-trending zone of minor faults. The ore is localized along interlacing small faults and along rolls in the bedding of the tuffaceous sedimentary rocks which strike NE, and are overturned and dip 45º to 55ºNW. The ore zone is essentially parallel to the bedding and zone of minor faults. Oxidation and enrichment to 30 feet deep.
The bleached, sericitized and silicified zone in the Bridle formation is of limited width, ranging only from several inches to 3 feet along the solution channels. Alteration also includes chloritization and pyritization.
The ore consists of massive granular, brown, resinous sphalerite in association with smaller quantities of Cu & Pb sulfides. Two major lenses of ore, one north and one south of the inclined shaft, center about 100 level, and a third major lens, south of the shaft centers about the 300 level.
Workings include 9 irregularly spaced levels and a total of more than 4,000 feet of workings. An inclined shaft is sunk to the lowest level (600). The ore averaged 46.89% Zn, 5.7 oz. Ag/T, 3.58% Pb and 1.68% Cu. Total production (1917-1951) was 120 oz. Au, 77,376 oz. Ag, 542,794 pounds Cu, 935,459 pounds Pb and 13,466,268 pounds of Zn.
