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 (Deposit): MINERALICATION IS WITHIN THIN LIMONITIZED QUARTZITE AND SCHIST LAYERS AS COPPER-RICH POCKETS. DIKES OF TERTIARY GRANODIORITE PORPHYRY CROP OUT NEARBY AND COULD BE POSSIBLE SOURCE OF MINERALIZING FLUIDS. ALTERNATIVELY, DEPOSIT COULD BE A VOLCANOGENIC MASSIVE SULFIDE

Comment (Workings): ADIT WITH CROSSCUT AND DRIFTS, SEVERAL PROSPECT PITS
