A Cu-Zn-Pb-Ag-Au-pyrite occurrence/prospect located in the NW¼NE¼SW¼ sec. 19, T23N, R17W, G&SRM, about 1½ miles SE of Mineral Park and 5 miles SE of Chloride, on Bureau of Land Management administered and/or private land. Owned by J. W. Haas, of Mineral Park, Arizona (1909). Owned by A.J. Jagerson, Arizona (1953). Owned by Duval-Pennzoil United, Incorporated, Texas (1978). The USGS MRDS database stated accuracy for this locality is 1,000 meters.
The Wood Chopper's Relief mine, owned by J. W. Haas, of Mineral Park, is about 1½ miles southeast of Mineral Park on the south side of the valley, in a steep northeastern slope of the mountain, at an elevation of about 4,500 to 4,700 feet. The country rock is the dark pre-Cambrian granite porphyry, extensively intruded by a light aplitic granite. The vein strikes nearly east and west and dips about 75° N. The mine is developed mainly by two tunnels, aggregating 500 feet in length and 200 feet of drift. The tunnels are situated 100 feet apart vertically; the lower one trends S.16°E. for a distance of 350 feet to the vein. Here in the face of a 33-foot drift to the east the vein contains 2 feet of quartz with pyrite, intrusive aplitic granite on the hanging wall. The vein looks well, but is said to carry only a little gold, with a trace of copper and silver.
The upper tunnel, situated on the same vein as the lower, lies mostly in the granite porphyry and in the oxidized zone. It contains 160 feet of drift that runs toward the west. Here the vein is 4 to 6 feet wide and consists mainly of iron-stained, streaked, and banded brecciated material. It has yielded considerable good ore, some of which averaged $500 in silver chloride and $4 in gold to the ton.
Mineralization is a polymetallic vein deposit hosted in granite. Precambrian schistosity strikes N30ºE. The mineralization is associated with a Late Cretaceous porphyry intrusion. Veins, fissures and dikes strike NW to NNW regionally. Associated rocks include Neoproterozoic granite. Local rocks include Early Tertiary to Late Cretaceous granitic rocks.
Workings include underground openings comprised of 2 tunnels (adits) with a total of about 500 feet of length plus about 200 feet of drifts.
