Satelite View

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

Comments
Comment (Location): 25 MILES NORTH OF NIXON, ON GRAVEL ROAD ONE SIDE OF WINNEMUCCA DRY LAKE, THEN EAST UP FACE OF STEEP SLOPE ON FIRST PROMINENT SWITCHBACK. ; INFO FROM LAND.ST :(1972)
Comment (Commodity): HIGH COUNT IS SPOTTY AND OF SUCH LOW GRADE AS TO MAKE THE DEPOSIT UNECONOMICAL
Comment (Deposit): NUMEROUS PEGMATITE DIKES AND SILLS OR DIKES OF GRANODIORITE INJECTED INTO METASEDIMENTS OF AULD LANG SYNE GROUP. DIKES AND SILLS HAVE GREATLY DISTORTED THE METASEDIMENTS. THESE ROCKS HAVE BEEN ALTERED 6-12 INCHES FROM THE PEGMATITE, AND STAINED BY LIMONITE. PEGMATITE IS WHITEHIGHLY FRACTURED WITH FELDSPAR CONVERTED ALMOST ENTIIRELY TO CLAY
Comment (Workings): ROADCUTS UP MOUNTAIN TO APPARENT SCHEELITE PROSPECT; DOZER CUT
