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.

Comments

Comment (Deposit): SEVERAL QUARTZ VEINS. CLOSELY SPACED QUARTZ VEINLETS WERE RICH ENOUGH TO MINE OVER WIDTHS OF 8-12 FT. SOME SILICIFIED SCHIST BETWEEN VEINS MAY CONSTITUTE LOW GRADE ORE. STIBNITE VEIN 20 IN WIDE

Comment (Workings): POST 1931 DATA SPARSE

Comment (Geology): MANY NORMAL FAULTS BUT MOVEMENT 20 FT OR LESS.

Comment (Deposit): SECOND LARGEST LODE-GOLD PRODUCER IN DISTRICT. POST 1931 PRODUCTION AND OTHER DATA MOSTLY LACKING, BUT 1931-1940 PRODUCTION WAS SUBSTANTIAL. SOME STIBNITE PRODUCTION. MANY STIBNITE LENSES AND VEINS. ; INFO.SRC : 1 PUB LIT
