A former surface and underground Au-Ag-Pb-Cu mine located in the N½ sec. 32, .14N., R.10W. (Kaiser Spring SE 7.5 minute topo map), south of Grayback Mountain. Produced 1932-1941.
Mineralization is a vein deposit with a tabular ore body hosted in the Hillside Mica Schist, vertical muscovite schist; lenticular - thin seam to 4 feet thick. Includes unspecified copper carbonates. Ore control was faulting and shearing. Ore concnetration was oxidation at near surface. No alteration was reported.
Area structures include minor foliation in schist trends NE. Local igneous rocks are massive. Veins are often at low angles, dipping less than 40 degrees.
Workings include a 70 foot inclined shaft; 2 short, near-surface drifts with small stopes.
