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.

Land Status

Land ownership: BLM Administrative Area
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments

Comment (Development): PRINCIPAL PRODUCTION PERIOD WAS 1874 TO 1897. THE OLD WORKING WERE REHABILITATED AND RENEWED EXPLORATION WAS UNDERTAKEN IN 1953 BY THE CONSOLIDATED EUREKA MINING CO.

Comment (Location): UTM PRECISION 100M

Comment (Deposit): PODS, REPLACEMENT VEINS AND IRREGULAR REPLACEMENT BODIES IN BRECCIATED ZONES AT INTERSECTIONS OF FAULTS AND FISSURES, AND ASSOCIATED WITH A SYSTEM OF CAVES.

Comment (Deposit): FROM 1874 TO 1897 57,800 TONS OF ORE VALUED AT $1,323,194 WERE PRODUCED FROM THE PROPERTY. THE OLD WORKINGS WERE REHABILATATED AND RENEWED EXPLORATION WAS UNDERTAKEN IN 1953 BY THE CONSOLIDATED EUREKA MINING CO. (NOLAN 1962). THE MINE IS LOCATED ALONG THE SOUTHERN PORTION OF PROSPECT RIDGE, ONE OF FIVE MINERALIZED BLOCKS IN THE DISTRICT. ; INFO.SRC : 1 PUB LIT

Comment (Geology): THE RICH OXIDIZED ORE WAS ASSOCIATED W/A SYSTEM OF CAVES, AS PODS, REPLACEMENT VEINS AND IRREGULAR REPLACEMENT BODIES IN BRECCIATED MASSIVE DOLOMITE. A FEW AREAS OF SILICA RICH ORE WAS MINED FROM QUARTZ-GALENA-TETRAHEDRITE VEINS AND REPLACEMENT BODIES
