A series of W-Cu-Pb-Ag-Mn-Mo mine workings located in the SW ¼ sec. 26 and the SE ¼ sec. 27, T.15S., R.22E, ½ to 1¼ miles SW of Johnson and 1.8 km SW of the Republic Mine. Discovered 1882. Owned by the Coronado Copper & Zinc Co.
Mineralization is a quartz vein deposit hosted in siltstone, with spotty hübnerite and minor scheelite, powellite, pyrite, galena and chalcopyrite in coarse quartz and iron and manganese oxides along irregular fissure veins in Precambrian Pinal Schist. The deposit is comprised of one fissure intermittently mineralized for 3,500 feet. The ore zone(s) are 243.84 meters long and 0.61 meters wide, strike N50-85E and dip steeply to the S. The veins often parallel schiostosity but sometimes cross it. Ore control was fissures. An associated rock unit is the Texas Canyon Quartz Monzonite (53 ± 3 MY).
Workings are open cuts and shallow underground workings (prospect pits and trenches) and shallow shafts to 6.1 meters deep; some short drifts. The largest open cut is 20 feet deep. The workings follow a milky quartz vein(s) along a ridge line in the vicinity of the Bluebird Mine and Bluebird East Mine, near Texas Canyon. The evident host rock is granitic Texas stock (Texas pluton). One trench has an exploratory shaft or raise at the bottom. It appears as if little, if any, ore was actually removed; however, it is reported to have produced a small quantity of tungsten ore, largely from placer operations prior to 1919.
