A former small underground Pb-Ag-Cu-Zn-Au mine located in the NW ¼ sec.4, T.16S., R.23E. (Dragoon 7.5 minute topo map), 4 miles SE of Johnson on the west side of the Gunnison Hills, and about 4 miles NE of Dragoon, on private land. Produced 1908-1935. Owned by C. and L. C. Chambers (1964). Formerly operated by the Texas Arizona Mining Co., Mills Chambers & S; O.F. Smith; and, B.F. Guilbert.
Not the State of Texas Mine in the same County. This mine is inactive but not abandoned and is strictly posted as under ownership. Access is only by hiking over public land since road access is denied due to deeded land (private property) between the public roads and the mine.
Mineralization consists of secondary lead, copper and zinc minerals, galena, and oxidized iron and zinc sulfides in tabular pyrometasomatic replacement bodies, streaks, bunches, and lenses in faulted Paleozoic limestones. Host rock units are the Escabrosa Limestone and the Martin Formation Devonian dolomite with some shale and sandstone. Ore control was favorable beds for replacement and fault fissues. Ore concentration was tabular replacement and fissure filling some enrishment. The ore zone is tabular at 27.43 meters long and 9.14 meters wide (0.13 meters thick), striking N25W and dipping 35NE. Other smaller bodies of ore were also mined. Alteration is the oxidation of ore to the deepest levels. The zinc minerals occur more often in fissures; lead minerals tend to be in replaced areas. Silver minerals are not identified, and may be argentiferous galena; some horn silver. The Martin and Escabrosa formations strike N25W and dip 35NE. Faults and fissures in the Escabrosa limestone and top of the Martin formation trend from NW to NE. The beds strike N25W and dip 35NE. Streaks of ore were found along these fissures. Tabular replacement deposits occur 80 to 120 feet stratigraphically above the base of the Escabrosa. The ore is oxidized to its lowest levels.
Local structures include Tertiary block faulting trending NW. Regionally, Late Cretaceous or Early Tertiary N- and NW-trending folds and thrust faults override to the NE. Also, faults trending E, NE, and NW.
The mine features an abandoned old shaft, circa 1881, and a new shaft, circa 1969, at 315 feet (126.49 meters) deep. The inclined shaft is 315 feet; two winzes from the 5th of five levels go an additional 40 and 100 feet. Total recorded production from 1910-1928 was 718 tons of ore averaging 38.5% Pb, 49 oz. Ag, 1.6% Cu and 0.05 oz. Au per ton, was produced intermittently from 1910 to 1928. No trespassing.
