A U-Cu deposit located in the center sec. 1, T41N, R19E, G&SRM (Agathla Peak 15 minute topo map), 8.9 km (5.5 miles) WNW of Mitchell Mesa (coordinates of record) (Mitchell Mining District), and 1.7 km (1.1 miles) SSE of Goulding (San Juan County, Utah).
Mineralization includes an U-Cu deposit with massive, medium-fine-grained Shinarump sandstone fills a paleochannel some 200 feet wide and 50 feet deep, cut into the Moenkopi Formation. Secondary copper and uranium minerals occur with abundant silicified wood and carbonized material. Local rocks include Permian to Pennsylvanian sedimentary rocks.

Stratigraphic Name: Hermit Formation; Supai Group; Schnebly Hill Formation; Naco Group
Description: Interbedded sandstone, shale, and limestone usually characterized by ledgy outcrops. Orange to reddish sandstone forms cliffs near Sedona. This unit includes Supai Group and Hermit Shale in northern Arizona and Naco Group in southern Arizona. It was deposited in coastal-plain to shallow-marine settings during time of variable and changing sea level. Rocks of this map unit in southern Arizona may be in part equivalent to Permian rocks of map unit P in central and northern Arizona. (280-310 Ma)
