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.

Comment (Deposit): ADITS IN CONTORTED SILICIFIED CARBONATE EXPOSE MINUTE AMOUNTS OF COPPER SULFIDES ALMOST ENTIRELY RESTRICTED TO STRONG VERTICAL JOINTS. TRACES OF GOLD IN RICHER SPECIMENS.

Comment (Workings): TWO SMALL ADITS DRIVEN.

Comment (Geology): LARGE MASSES OF CONTORTED CARBONATE ABOVE THRUST FAULTS HAVE BEEN COMPLETELY REPLACED BY SILICA. INTENSELY SILICIFIED CARBONATE ROCKS (MOSTLY MARBLE).
