A former surface and underground Cu-Au-Ag-Fluorspar mine located in the WΒΌ sec. 6, T.8N., R.2W. (Morgan Butte 7.5 minute topo map), near Copperopolis at 3,225 feet of altitude. Owned by John Dobler (1926). Discovered in 1890 by Mr. Dobler. Produced 1910-1966. Claims extend into sec. 7, T8N, R2W and secs. 1 & 12, T8N, R3W.

Mineralization is a post-Tertiary Au-Cu vein with a tabular ore body. Country rock is Bradshaw Granite with dikes of andesite and granite porphyry. The vein strikes N.10ΒΊW. and dips 70ΒΊE. The ore averages 3 to 15 feet wide. A second vein strikes N.33ΒΊW. and dips 60ΒΊE. Ore control was faulting and shearing. Ore concentration was oxidation at near surface. Alteration was minor Fe-staining.

Area structures include veins parallel to low-angle (less than 50 degrees dip) faults which trend NW. Foliation in Precambrian schist trends N20E to N50E. Tertiary volcanics dip NE and strike NW.

Workings include the south shaft at 225 feet deep (Β½ mile SE of Buzzard's Roost), and a second shaft at 300 feet deep located north of the house and 300 feet above it. A 10-stamp mill was erected. Produced 1 to 2 oz. Au/T.
