California Mountain Mine


Second-largest mercury producer in the district.

Deposit: Cinnabar replacement of clay matrix in collapse breccia

Development: Econ.com: a Scott furnace installed 1899. Mariposa mining co. operated two 10 tpd (ton per day) Scott furnaces and leased the 50 tpd Terlingua furnace during World War I. F.W. Oakes Jr. installed a 30 tpd rotary furnace in 1928 which was moved to the Study Butte mine in 1930.

Geology: Cretaceous Limestone and shale is cut by NW trending normal faults; host: Grayson Fm shale, Devil's River limestone intruded by soda latite dikes and sills

Rock formation(s): Santa Elena Limestone; Del Rio Clay

Ore(s): Solution collapse along limestone-clay contact.
