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 (Development): IN THE 1860'S, A 900-FT. TUNNEL WAS DRIVEN ON THE OCCIDENTAL CLAIM, FROM WHICH A LARGE TONNAGE OF GOOD ORE WAS STOPED. IN 1870, A TUNNEL 400 FT. LOWER ENCOUNTERED LITTLE ORE. LATER WORK WAS BY LESSEES

Comment (Workings): TUNNELS

Comment (Geology): OCCIDENTAL VEIN PARALLELS THE MAIN COMSTOCK LODE, 1 1/2 MILES TO THE EAST

Comment (Deposit): IN THE 1860'S A 900-FT TUNNEL WAS DRIVEN INT HE OCCIDENTAL CLAIM. A FAIRLY LARGE TONNAGE OF ORE WAS STOPED FROM ABOVE THIS TUNNEL AND FROM WINZES. IN 1870 A TUNNEL 400 FEET LOWER ENCOUNTERED ORE, BUT THIS LOWER DEPTH YIELDED LITTLE ORE. THERE WAS REPORTED FROM 1866 TO 1894 A PRODUCTION OF $400,000 FROM NEARLY 40,000 TONS OF ORE. SINCE THAT TIME LEASERS HAVE WORKED THE MINE. TOTAL PRODUCTION 1868-1894 WAS 25798 TONS ORE AVERAGING $17.08 PER TON ; INFO.SRC : 1 PUB LIT
