A former underground Au-Ag-Cu-Zn-Pb mine located at the mouth of Fool's Gulch, about 5 miles NE of Congress Junction. Discovered by Henry L. Scott in 1905. Produced 1935-1943. Claims are also in the N½ sec. 21.

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

Area structures include veins parallel to mafic dikes which 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.

Workings include 2 inclined shafts approximately 800 feet deep.
