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 (Development): WESTERN MINING CURRENTLY HOLDS THE LEASE.
Comment (Deposit): DEPOSIT CONSISTS OF NEARLY MASSIVE PODS OF ARGENTIFEROUS GALENA REPLACING LIMESTONE. REPLACEMENT IS LOCALIZED ALONG A GRANODIORITE DIKE THAT WAS INJECTED ALONG A FAULT, BOTH STRIKING WNW. MINERALOGY CONSISTS OF GALENA WITH TRACE AMOUNTS OF PYRITE INCLUSIONS
Comment (Workings): WORKINGS CONSIST OF ONE DOZER CUT, ABOUT 50 FEET LONG, AND A SMALL PIT.
Comment (Geology): GRANODIORITE DIKE IS PRESUMABLY RELATED TO NEARBY STOCKS OF GRANODIORITE THAT HAVE BEEN DATED.
Comment (Commodity): A POLISHED SLAB SHOWED ONLY GALENA AND A TRACE PYRITE PRESENT, SUGGESTING THAT AG IS IN GALENA.
