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 (Geology): A CROSSCUT DRIVEN INTO THE FOOTWALL OF THE RUBY HILL FAULT FROM THE 840' LEVEL PENETRATED 450 FEET OF PROSPECT MTN QUARTZITE BEFOR ENTERING QUARTZ DIORITE. THE QUARTZITE CONTAINED SMALL AMOUNTS OF MOS2 THROUGHOUT. ON THE 1200 FOOT LEVEL MASSIVE PYRITE OCCURS ALONG A FAULT ZONE.

Comment (Location): UTM PRECISION 100 M

Comment (Development): EXPLORTORY DRILLING DONE FROM 900 LEVEL IN 1940'S BY THE EUREKA CORP AND USBM. DRILLING REVEALED PB-ZN ORE 2000' BELOW SURFACE. FAD SHAFT WAS SUNK TO DEVELOP THE ORE LOCAN SHAFT WAS ORIGINALLY SUNKIN 1920

Comment (Deposit): ORE ZONES CONTROLLED BY FAULT ZONES, INTRUSIVE CONTACT

Comment (Workings): 4 SHAFTS AND SEVERAL LEVELS OF UNDERGROUND WORKINGS

Comment (Deposit): THE PROPERTY IS LOCATED WITHIN THE RUBY HILL AREA, THE RICHEST OF THE FIVE MINERALIZED BLOCKS IN THE DISTRICT. EXPLORATORY DRILLING WAS DONE FROM THE 900 LEVEL IN THE 1940'S BY THE EUREKA CORP AND USBM. THE DRILLING REVEALED P3-ZN SULFIDE MINERALIZATION 2000 FT. BELOW THE SURFACE. THE FAD SHAFT WAS SUNK TO TRY AND DEVELOPE THIS ORE ZONE. THE LOCAN SHAFT WAS ORIGINALLY SUNK PRIOR TO 1920 IN SEARCH FOR DOWNFAULTED ORE ALONG THE RUBY HILL FAULT ALONG WITH THE LAWTON SHAFT AND THE KK SHAFT THEY COMPRISED THE WORKINGS OF THE EUREKA CONSOLIDATED CO.
