Satelite View

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

Comments
Comment (Deposit): WORKINGS WERE DEVELOPED TO EXPLORE EXTENT OF A 1 FOOT THICK QUARTZ-RICH MINERALIZED SHEAR ZONE. SHEAR ZONE SHOWED TRACES OF COPPER MINERALS AND LIMONITE. EFFORTS TO LOCATE DOWN-DIP EXTENT OF SHEAR ZONE ON THE SURFACE SHOWN BY 3 PITS IN APLITE ; INFO.SRC : 3 FIELD OBSERV; 4 OTHER SRC
Comment (Deposit): SHEAR ZONE IS DEVELOPED ALONG THE FOOTWALL CONTACT OF A NORTH-WEST STRIKING APLITE DIKE. ZONE IS CONSISTENTLY 1 FOOT THICK.
Comment (Workings): WORKINGS CONSIST OF 20' OF DRIFT ALONG STRIKE OF SHEAR ZONE. AT DRIFT FACE IS A WINZE THAT FOLLOWS ZONE DOWN DIP. IT IS FULL OF MUCK 10 FEET DOWN. THREE SMALL PROSPECT PITS ON SURFACE DOWN DIP FROM ADIT FAILED TO HIT ANYTHING BUT APLITE
