The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comment (Commodity): Ore Was Of Gem Quality
Comment (General): Situated on the west slope of Bald Mountain, 2 miles north of Sonora. It is a pocket mine in mica schist of the Calaveras formation. The vein has a course of N. 57? E., and dip 60? NW. Two tunnels on the vein; lower tunnel 1800 feet in length, and 80 feet above it another one 500 feet long. The ore shoots or pockets occur near east and west granite crossings, which reefs are from 8 to 60 feet wide and dip to the south. Rich pockets are formed at the point where these crossings come in contact with the vein in a belt of black slate, also with quartz stringer feeders having same course as vein, but dipping faster into the main vein near a crossing. The quartz is free milling, containing coarse gold associated with tellurides of gold and silver. Two men are employed. C. F. Smith and C. R. Watson et al., of Sonora. owners.
