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: Private
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 (Location): LOCATION IS ACCURATE FOR THE PORTAL OF THE ADIT. ; INFO FROM LAND.ST :1979

Comment (Production): PRODUCTION TOTALLED 55,717 TONS OF ORE. THE MINE PRODUCED FROM 1952-1959 AND 1964-1970.

Comment (Deposit): THE ORE IS FOUND IN TWO MEDIUM TO LARGE DEPOSITS AND SEVERAL SATELLITES MOSTLY IN THE BASAL UNIT OF THE DAKOTA SANDSTONE. THE UNIT FILLS CHANNELS SCOURED IN THE JURASSIC MORRISON FORMATION, AND IS OVERLAIN BY CARBONACEOUS SHALE AND INTERBEDDED FINE-GRAINED SANDSTONE. THE BEDS STRIKE N30W AND DIP ABOUT 30SW. THE TWO MAIN DEPOSITS ARE ABOUT 750 FT APART ALONG THE STRIKE. THE ORE BODIES PINCH OUT ABOUT 275 FEET VERTICALLY BELOW THE MINE ENTRY AT THE OUTCROP. THE ORE OCCURS IN PODLIKE MASSES, GENERALLY ELONGATE WITH THE DIP OF THE BEDS AND PARALLEL TO THE AXES OF CROSS-FOLDS AND TO THE PLUNGE OF SLUMPLIKE STRUCTURES IN THE HOST SANDSTONE.

Comment (Workings): WORKINGS CONSIST OF TWO 28-DEGREE DECLINES AND AN OPEN PIT. THE DECLINES ARE DRIVEN DOWN DIP AND THE PORTALS ARE ABOUT 125 FEET APART ALONG STRIKE. THE OPEN-PIT LIES ON TOP OF THE HOGBACK.

Comment (Geology): THE DEPOSIT OCCURS IN THE CRETACEOUS DAKOTA SANDSTONE SCOURING THE JURASSIC MORRISON FORMATION (WESTWATER CANYON MEMBER).
