A small former surface and underground Cu-Zn-Ag-Pb-Au mine located in the NE ¼ sec. 24, T.18S., R.23E. Discovered 1937. Produced 1937-1947. Owned by Mr. Ed Festerling (1958); operated by Alejo and Juan Antunez (1958).

Mineralization is sulfides in irregular replacement bodies along faults in Cretaceous Bisbee Group limestone. Oxidation was strong.

Local structures include limestone beds which strike NNW and dip 50NE.

Workings are a shaft(s) and surface openings. A few tens of tons of ore were produced between 1937 and 1947.

ID: 2847784
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)
