A former small underground Pb-Zn-Ag-Cu-Au mine located in South-central sec. 13, T. 11 S., R.16E, 4 miles east of Marble Peak. Produced 1951-1957. Owned at times, or in part, by Mr. Marvin Combs (1956-1957); and, Hill.

Mineralization is a replacement deposit with an irregular ore body with spotty and irregular, partly oxidized lead, zinc and minor copper sulfides in Paleozoic limestone. Ore control was a fracture or fault near, but not on, a contact with an intrusive body. Alteration was oxidation. An associated rock unit is diorite.

Local structures include intrusives into Paleozoic limestones.

Workings include tunnels. Produced sporadically during 1951-1957, of some 80 tons of ore averaging about 13% Pb, 3% Zn, 3 oz. Ag/T and minor Cu & Au. Assumed to be adit shown on NW slope of Alder Canyon.

Description: Brown to dark gray sandstone grades upward into green and gray shale, overlain by light to medium gray or tan limestone and dolostone. This unit includes the Tapeats Sandstone, Bright Angel Shale, Muav Limestone, Temple Butte Formation and Redwall Limestone in northern Arizona, and the Bolsa Quartzite, Abrigo Formation, Martin Formation, and Escabrosa Limestone in southern Arizona. These rocks record intermittent sea-level rise and inundation in early Paleozoic time. (330-540 Ma)
