A former small Pb-Ag-Cu-Au mine located in the SE ¼ sec. 14, T.23S., R.19E. Locality unsurveyed. Located about 1 mile SW of the southern boundary of the Fort Huachuca military reservation. Closed 1951. First produced 1900. Operated by Mr. L. D. Carlisle (1951).

Mineralization is spotty sulfides, alrgely oxidized, in quartz veins in shale and sandstone of the steeply tilted Cretaceous Bisbee Group Morita Formation cut by Tertiary dikes or sills.

Workings include tunnels. A small production of ore was made in the early 1900's and in 1951.

Cretaceous
66 - 145 Ma



ID: 3187054
Mesozoic sedimentary rocks

Age: Cretaceous (66 - 145 Ma)

Lithology: Sedimentary rocks

Campanian - Oxfordian
72.1 - 163.5 Ma



ID: 2847800
Cretaceous to Late Jurassic sedimentary rocks with minor volcanic rocks

Age: Mesozoic (72.1 - 163.5 Ma)

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)
