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): THE PEGMATITE IS A POD-LIKE BODY THAT TRENDS NORTH-NORTHEAST IN CONFORMITY TO THE STRIKE OF THE FOLIATION OF THE AMPHIBOLE SCHIST COUNTRY ROCK. THE PEGMATITE DIPS SLIGHTLY WEST-NORTHWEST IN CONTRAST TO THE STEEP EAST-SOUTHEAST DIP OF THE COUNTRY ROCK. A ZONAL STRUCTURE IS EVIDENT WITH AN INNER CORE OF MASSIVE QUARTZ AND THREE OUTER ZONES. THE RARE-EARTH AND URANIUM MINERALIZATION WAS FOUND ON THE WEST AND NORTH SIDES OF THE PIT ALONG THE UPPER CONTACT OF A MICA-RICH "STREAK". MINERALS PRESENT INCLUDE SMOKY QUARTZ, COLUMBITE, HATCHETTOLITE, URANINITE, SAMARSKITE, EUXENITE (OR FERGUSONITE, BISMUTITE, AND GUMMITE. GANGUE MINERALS INCLUDE MICROCLINE, ALBITE-OLIGOCLASE AND QUARTZ. JAHNS (1946) PROVIDES AN EXCELLENT DESCRIPTION OF THE DEPOSIT.
Comment (Workings): WORKINGS CONSIST OF ONE PIT 10 FEET IN DIAMETER AND 10 FEET DEEP.
Comment (Geology): THE PRECAMBRIAN IN THIS AREA HAS NO FORMAL NAME.
Comment (Location): LOCATION IS ESTIMATED FROM REDMON'S (1961, P. 73) DIRECTIONS. THE CADASTRAL GRID IS PROJECTED IN THIS AREA. ; INFO FROM LAND.ST :(1979)
Comment (Production): PRODUCTION FROM THE PEGMATITE IS REPORTED TO HAVE BEEN 990 POUNDS OF SCRAP MICA AND AT LEAST 350 POUNDS OF TANTALUM, URANIUM AND RARE EARTH MINERALS.
