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 (Location): UTM COORDINATES TO ADIT NEAR END OF ROAD. ADIT ON SHAMROCK #3 PATENTED CLAIM. INCLINED SHAFT ON MONICA CLAIM IN FAR NORTHWEST CORNER OF SECTION 28

Comment (Development): PATENTED CLAIMS INCLUDE SHAMROCK #3, YELLOW STONE, MOONSHINE, PAPOOSE, MONICA, NUGGET, RED ROCK, AND OTHERS

Comment (Deposit): VEIN OF QUARTZ APPARENTLY NOT CONTROLLED BY ANDESITE DIKES. BOTH ANDESITE AND RHYOLITE DIKES ARE CUT BY TUNNEL BUT NO APPARENT MINERALIZATION ASSOCIATED WITH THEM

Comment (Workings): 1200 FT LONG TUNNEL CONNECTS TO INCLINED RAISE WHICH SURFACES 2260 FT SOUTH 50 E FROM MAIN ADIT. OVERALL AREA PROBABLY OVER ESTIMATED.

Comment (Geology): DEPOSIT IS QUARTZ VEIN WHICH CUTS PRECAMBRIAN ROCKS. ANDESITE AND DIORITE DIKES TREND NORTHWEST AND APPARENTLY ARE NOT RELATED TO THE VEINS
