A former small underground Pb-Zn-Ag-Cu-Au-Baryte mine located in the NE ¼ sec. 26, T.19S., R.15E., near the head of Hughes Gulch and 1½ miles southwest of Greaterville, west of Granite Mountain, in Nigger Gulch, at an elevation of 5,840 feet, 37 miles SE of Tucson. Discovered 1883. Owned at times, or in part, by the Quebec Consolidated Mining Co.; and, Hurlbut & Christman.

Mineralization is a well-banded, iron-stained, quartz-calcite-barite 4 foot wide NW-SE vein containing irregular pockets of partially oxidized sulfides along a Tertiary quartz-latite stock intruding Cretaceous sedimentary formations. The vein is in coarse, dark porphyritic granite. The vein is about vertical. Host rock units include Apache CAnyon Formation and the Willow Canyon Formation. Gold content tends to increase in calcite-baryte gangue.

Local structures include thrust and normal faulting, fracture zones, homoclinal. Regional trends include tilting and broad open folds in the south and extensive faulting in the north.

Workings include a 50 foot deep shaft and a 100 foot tunnel with a 50 foot upraise from the breast to the surface, and a 20 foot deep winze to a 50 foot drift and a 25 foot deep winze at the end of the drift. Worked in the 1880's and sporadically up to 1940, producing a small tonnage of Pb-Ag ore with minor Au & Cu. Ore shipped inj the early days is reported to have averaged 100 oz. Ag/T and a little gold.

Stratigraphic Name: Temporal Formation; Bathtub Formation; Sand Wells Formation; Fort Crittenden Formation; McCoy Mountains Formation

Description: Sandstone and conglomerate, rarely forms prominent outcrops; massive conglomerate is typical near base of unit and locally in upper part. These deposits are nonmarine except in southeastern Arizona, where prominent gray marine limestone (Mural Limestone) forms the middle of the Bisbee Group. Sandstones are typically medium-bedded, drab brown, lithic-feldspathic arenites. Includes Bisbee Group (largely Early Cretaceous) and related rocks, Temporal, Bathtub, and Sand Wells formations, rocks of Gu Achi, McCoy Mountains Formation, and Upper Cretaceous Fort Crittenden Formation and equivalent rocks. (80-160 Ma)
