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): MANGANESE OXIDES IN PIPELIKE BODIES OF CALLAREOUS AND OPALINE SPRING SINTER . SOME OF THE VEIN MATERIAL IS MN-RICH CHALCEDONY, OTHERS ARE VUGGY MN-RICH QUARTZ. MANY OF THE LATTER TYPE LOOK LIKE THE OUTCROPS OF THE MOHAWK VEIN, AND MAY HAVE BEEN THE REASON FOR SO MUCH PROSPECTING ON THESE DEPOSITS

Comment (Workings): TRENCHES, PROSPECT PITS AND A SHAFT

Comment (Location): POOR ACCESS THE LAST HALF MILE ; INFO FROM LAND.ST :(1972)

Comment (Development): EARLY EXPLORATION WAS PROBABLY NOT FOR MN BUT FOR PRECIOUS METALS
