A former underground Au-Ag-Cu-Pb. Discovered by Harrison Yarnell. Produced 1936-1941. Claims also located in sec. 23.

Mineralization is a tabular ore body. Ore control was faulting, shearing and igneous activity. Ore concentration was oxidation at near surface. Alteration was minor sericite along vein walls.

Area structures include veins that trend NE and dip at low angles, usually less than 40 degrees. Foliation in Precambrian metamorphic rocks trends N10E to N25E. Local granitic rocks are unfoliated.

Calymmian
1400 - 1600 Ma
Middle Proterozoic granitic rocks

Age: Calymmian (1400 - 1600 Ma)

Stratigraphic Name: Oracle Granite; Ruin Granite

Description: Mostly porphyritic biotite granite with large microcline phenocrysts, with local fine-grained border phases and aplite. Associated pegmatite and quartz veins are rare. This unit forms large plutons, including the Oracle Granite, Ruin Granite, granite in the Pinnacle Peak - Carefree area northeast of Phoenix, and several bodies west of Prescott. (1400-1450 Ma)

Comments: ~ 1.4 Ga

Lithology: Major:{granite}, Minor:{aplite}, Incidental:{pegmatite}
