A former small underground Pb-Ag-Au mine located in the NE ¼ sec. 11, T.20S., R.22E, ½ mile S of Tombstone, on private land. Situated 500 feet SW of the Toughnut and Girard shafts.

Mineralization is oxidized, argentiferous and auriferous lead ores in Cretaceous Bisbee Group beds, controlled by the intersection of fissures and anticlinal rolls. The main fissure trends NE.

Local structures include the Tombstone Basin with beds tilted NNE after mineralization.

Workings include a shaft(s). One shaft with 8 levels of workings. The main workings are linear along a NE-trending fissure. Several tens of thousands of tons of ore were produced, mainly in the late 1880's and early 1900's. Post-1900 production statistics were included under the Tombstone group in ABGMT-USBM file data.

ID: 3187054
Mesozoic sedimentary rocks

Age: Cretaceous (66 - 145 Ma)

Lithology: Sedimentary rocks

ID: 2946362
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)
