Satelite View

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

Comments
Comment (Deposit): DEPOSIT LIES CLOSE TO A ZONE OF CROSS FAULTING. HOSTROCKS ARE HIGHLY SHEARED AND ALTERED. MINERALIZATION IS CONTROLLED BY FISSURES AND FRACTURES.
Comment (Workings): THREE ADITS (155, 60, 425 FT); AN INCLINE SHAFT AND A WINZE; THE UPPER TWO LEVELS ARE ENTIRELY IN QUARTZITES. THE LOWER TUNNEL IS IN THE INTRUSIVE ROCKS AND ALSO IN QUARTZITES, BANDED LIMESTONE, WHITE LIMESTONES AND MARBLES.
Comment (Geology): THE LIMESTONE IS DARK GRAY TO BLACK, WEATHERING LIGHT GRAY BLUE WITH A SMOOTH SURFACE, VERY FINE-GRAINED, THIN BEDDED TO PLATY, WITH SOME SILT STRINGERS AND SMALL 1/2" TO 1" DIAMETER BLACK ROUNDED CHERT NODULES. VEINS OF QUARTZ AND CALCITE ARE COMMON.
