Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Deposit): QUARTZ VEIN WITH PITS AND TRENCHES DUG ON IT. ADIT IN MULE SPRINGS LIMESTONE; DISSEMINATED GALENA AND SPHALERITE PRESENT IN MARBLE. GARNET-PYROXEIVE TACTITE PRESENT IN THE SAME HORIZON FURTHER WEST. VERY LARGE ZONED GARNET, SOME COPPER OXIDE IN TACTITE. SOME WORKINGS APPEAR TO BE ALONG A N-TRENDING THRUST FAULT WHICH JUXTAPOSES CAMBRIAN CAMPITO FORMATION OVER CAMBRIAN MULE SPRINGS LIMESTONE. MINERALIZATION OCCURS AS SULFIDES DISSEMINATED THROUGHOUT QUARTZITE/MUDSTONE AND IN BRECCIA. ROCKS ARE HEAVILY FE-STAINED. ORE IS LOCALLY SILICIFIELD. CRYSTALLINE APLITIC DIKES CUT HOST ROCKS, WHICH ALSO CARRY FRESH PYRITE AND CHALCOPYRITE. QUARTZ VEIN MATERIAL WITH CALCITE OBSERVED.
Comment (Workings): SEVERAL SHAFTS, ADITS, SURFACE CUTS, TRENCHES AND PITS; ROADS REPAIRED
Comment (Geology): LAMPROPHYRE SILL OCCURS ON RIDGECREST, BUT HAS NO OBVIOUS ASSOCIATION WITH THE MINERALIZATION.
Comment (Development): ASSESSMENT WORK DONE BY SWANSONS SINCE 1968 AND IS CURRENT.
Comment (Location): RECOMMENDED ACCESS IS FROM THE NORTH FROM U.S. HIGHWAY 95. UNSURVEYED AREA. ; INFO FROM LAND.ST :(1972)
