|Eastern Mojave Vegetation||Southern Belle Mine, Mono County, California.|
Location not confirmed.
Gold and silver mine low on the western slope of the White Mountains. Type locality of Senecio monoensis Greene.
Directions: from the intersection of US Highway 395 and US Highway 6 in Bishop, go 7.8 miles north, turn right on Rudolph Road, heading generally east for 1.9 miles.
Also known as the Southern Bell and the Inyo Gold, worked from 1893-1937, producing 339 tons of ore and 1,024.77 oz of gold, and 182 oz. of silver (Diggles, et al., 1983).
Summary: Intensely folded and faulted argillite, hornfels, phyllite, shale, and marble are broken by steeply-dipping tensional faults that trend N. 30° to 70° W. The 0.1- to 2.9-ft-thick quartz veins that fill these faults contain gold, copper sulphides, and iron oxides.
Working and production: The main working has several portals, connected by more that 3,900 ft. of drifts, stopes and winzes. Surface workings include numerous pits. On the south end of the property are 11 adits, six trenches, four shafts, and three pits. The New Year shoft is reported to be 260 ft deep with development on three levels. Combined production from 1893 through 1937 was 1,024 oz gold and 182 oz silver (U. S. Bureau of Mines production records).
Resource/sample data: Twelve of 24 samples contained 0.016 to 0.216 oz gold and 0.2 to 1.0 oz silver per ton. Six samples contained 0.06 to 3.10 percent copper. Only a cursory examination was performed, mainly to determine if mineralized structures would trend into the study area. The potential for gold-silver-copper resources is high.
