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 (Workings): MAIN SHAFT AT LEAST 40 FT DEEP, FROM WHICH LEVELS ARE SAID TO HAVE BEEN RUN. THE SHAFT IS EQUIPPED WITH A "BABY" HOIST, AND THE SIZE OF THE DUMP WOULD INDICATE THAT PERHAPS 200 LINEAR FT OF UNDERGROUND WORK.

Comment (Geology): CONSIDERABLE GLACIAL DRIFT IS STREWN OVER THE SURFACE. OUTCROPS RANGE FROM A RUSTY QTZ-MICA SCHIST CONTAINING VEINLETS OF APLITE, PEGMATITE, AND QTZ TO A BANDED HORNSTONE, PORTIONS OF WHICH HAVE DISINTIGRATED TO GOSSAN-LIKE MASSES OF LIMONITE SHOWING THE STAIN OF MN OXIDES. THE SULFIDES AND MAGNETITE ARE INTERGROWN WITH THE SILICATES AND APPEAR TO HAVE BEEN INTRODUCED WHEN THE ROCKS WERE METAMORPHOSED. ; GEOL.DESC: SED. ROCKS SURROUNDED, METAMORPHOSED BY GRANITE

Comment (Deposit): SMALL BODY OF SEDIMENTARY ROCK SURROUNDED AND METAMORPHOSED BY GRANITE.

Comment (Development): SHAFTS WITH LEVELS; BABY HOIST.

Comment (Deposit): 3 CLAIMS.
