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 (Workings): SURFACE CUT 25 FT. LONG AND 6 - 8 FT. WIDE DRIVEN SW INTO SLOPE 20 FT. HIGHER AND TO THE SOUTH, A 15 FT. NEARLY VERTICAL SHAFT HAS BEEN SUNK. ANOTHER TACTITE BODY HAS BEEN EXPLORED BY 60 FT. TRENCH AND SHALLOW UNDERHAND STOPE, 15 FT. MAX DEPTH. OTHER WORKINGS ARE SMALL STRIPPED AREAS AND SHALLOW CUTS.
Comment (Geology): GEOL.DESC: MOST OF MINE AREA IS UNDERLAIN BY ARCHEAN GNEISS AND BIOTITE SCHIST, CUPPED BY PLEISTOCENE TUFF AND BASALT. SMALL THIN LENSES OF LIMESTONE IN SCHIST. THE ARCHEAN ROCKS CONTAIN IRREGULAR INTRUSIVE BODIES OF QUARTZ DIORITE. LIMESTONE NEAR QTZ. DIORITE CONTAINS SMALL, DISCONTINUOUS BODIES OF FRIABLE, GARNET-RICH TACTITE. CONTACT OF PRECAMBRIAN GNEISS AND SCHIST WITH LIMESTONE.
