About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

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 (Geology): THE BERYLLIUM TUFF MEMBER HOSTS ALL ORE ZONES; THE PORPHYRITIC RHYOLITE SERVED AS AN IMPERMEABLE BARRIER FOR MINERALIZING FLUIDS AND IS NOT MUCH MINERALIZED. ; MAJOR.UNITS: BERLLIUM TUFF MEMBER OF SPOR MOUNTAIN FORMATION (MIO); PORPHYRITIC RHYOLITE MEMBER OF SPOR MOUNTAIN FORMATION (MIO)

Comment (Deposit): ORE DEPOSIT CROPS OUT AT SURFACE AND DIPS ABOUT 18 DEGREES SOUTHWEST BENEATH RHYOLITE CAP ROCK; AT 200 FT DOWN DIP FROM OUTCROP TOP OF ORE IS ABOUT 50 FT. BELOW SURFACE. ORE DEPOSIT RANGES FROM 14-24 FT. THICK.

Comment (Workings): DIMENSIONS ESTIMATED VISUALLY WHEN VISITED IN 1986
