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 (Production): By far the most productive mine in the district, total quantities of metals from the Bassick are not available. Estimated production from 1877 discovery to 1885 was about $2 million or 80,000 oz. gold and several hundred thousand oz. silver, but little has been produced since.
Comment (Reserve-Resource): A summary report describes recent (1990s) exploration activities, but no resources have been developed. (Sunshine files)
Comment (Workings): A VERTICAL SHAFT, PLUS AT LEAST 12 LEVELS BELOW HAULAGE ADIT 150 FT BELOW THE SURFACE
Comment (Deposit): ORE-BEARING VEINS CUT TRACHYTE; AT LEAST TWO PARALLEL VEINS KNOWN
Comment (Geology): High-grade ore bodies occurred as steeply plunging breccia pipe-like bodies and fissure veins in volcanic rocks. Although the pipes were small in cross section, they persisted to depths greater than 1700 ft.
Comment (Location): On Bassick Hill 2 miles north of Rosita and just north of Querida, in the NE/4 NW/4 sec. 21, T 22 S, R 71 W.
