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.

Comments

Comment (Deposit): OVAL PEGMATITE CONSISTS OF WALL ZONE OF QUARTZ-MICROCLINE-BIOTITE AND CORE OF MICROCLINE-QUARTZ. CROSSCUTTING REPLACEMENT OF FLUORITE, YTTROFLUORITE, GADOLINITE, AND MONAZITE. SELECTIVE FLUORITE REPLACEMENT OF GRAPHIC GRANITE IN WALL ZONE PRODUCES FLUORITE-FELDSPAR ROCK.

Comment (Development): LAST REPORTED PRODUCTION WAS 20 ST RAE AND QTZ IN 1965

Comment (Workings): OPEN CUT

Comment (Location): ALONG UNNAMED TRIBUTARY OF SPRING CREEK 2 MILES ENE OF LONG SCRAGGY PEAK ; INFO FROM LAND.ST :(1975). Location confirmed based on description in RS-11 compared with topo and satellite imagery.

Comment (Orebody): 100' X 120', oval. Wall zone. Core is composite of quartz + microcline. Minor replacement. Cross-cutting replacements of fluorite, yttrofluorite, gadolinite, monazite; selective fluorite replacement of wall zone graphic granite producing graphic fluorite-feldspar rock. Mined for quartz, feldspar, and rare earths. (RS-11, p. 98, #20).
