Locality type:


A Au-Ag-Pb mining area located around Buckeye, Btridgeport and Buckeye Creek.

This is a small lode-gold district in southwestern Mariposa County about eight miles south of the town of Mariposa. The principal gold sources in the district were the Granite King and Live Oak mines, which were worked from the 1870s through the early 1900s and again from 1938 to 1941. The gold-quartz veins are two to five feet thick, strike to the northeast, and occur in granodiorite. The ore contains native gold, pyrite, galena, and sphalerite. Milling ore averages about 1/4 ounce of gold per ton with occasional pockets
of high-grade ore.
