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): LOCATED IN SE 1/4 NW 1/4 SECTION 5
Comment (Workings): A 25FT.SHAFT;SURFACE TRENCHING
Comment (Geology): GEOL.DESC: TWO ORE BODIES OF MASSIVE SILICEOUS ORE LIE PARALLEL TO THE BEDDING OF THE ENCLOSING GREEN CHERT AND SHALE. THE STRIKE IS N 65 W AND ARE NEAR VERTICAL ON A HIGH ANGLE TO THE NORTH. PSILOMELANE IS THE PRINCIPLE METALLIFEROUS CONSTITUENT OF THE ORE BUT NEAR THE SURFACE A SMALL QUANTITY OF MANGANESE DIOXIDE IS PRESENT.
Comment (Production): NO PRODUCTION. THE NORTHERN ORE BODY IS 5-7 FT. THICK AND THE SOUTHERN ORE BODY , SEPARATED FROM THE FIRST BY 6 FT. OF BARREN CHERT, IS AT LEAST 3 FT. THICK. ORE MINERALS ARE OXIDES OF MANGANESE, CARRYING A VARIABLE QUANTITY OF WHITE GRANULAR SILICA IN IRREGULAR PATCHES. PSILOMELANE IS PRINCIPAL METALLIFEROUS CONSTITUENT OF THE ORE BUT NEAR THE SURFACE A SMALL QUANTITY OF MANGANESE DIOXIDE IS PRESENT. MOST OF THE ORE IS TOO HIGH IN SILICA TO BE MARKETED WITHOUT RESORT TO SOME PROCESS OF CONCENTRATION
