Mine Info
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.

Comment (Deposit): SPOTTY VEIN QUARTZ OCCURS ALONG A STEEP N10W SHEAR ZONE IN PROBABLE METAANDESITE OF THE SONOMA RANGE FM. THE VEIN QUARTZ IS WHITE (MILKY) AND CONTAINS (WHERE NOT OXIDIZED PYRITE AND ARSENOPYRITE (?) THE ARSENOPYRITE (?) IS COMMON ON ONE DUMP. THE VEIN IS PROBABLY LESS THAN 30 CM WIDE AND THE WALL ROCKS ARE LOCALLY BLEACHED NEAR THE VEIN.
