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.

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.

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): INFO FROM LAND.ST :(1972)
Comment (Workings): MAIN ADIT TRENDS S 10 W FOR APPROXIMATELY 20-25 FT THEN TURNS MORE TO SW, APPROXIMATELY S 45 W, MAYBE 200+ FT LONG, WITH FAIRLY LARGE DUMP. 3 SMALLER WORKINGS ABOVE THIS ADIT APPROXIMATELY 200 FT
Comment (Development): NO ACTIVITY IN 1984; FAIRLY OLD WORKINGS, LARGEST WORKINGS IN THE AREA
Comment (Deposit): LIGHT TO MEDIUM-GRAY PHYLLITE WITH MINOR AMOUNTS OF MILKY WHITE QUARTZ ON DUMP, AS WELL AS APLITE DIKE MATERIAL ON DUMP. UPPER WORKINGS (2 VERY SHORT ADITS) ARE IN FE-STAINED META-INTRUSIVE ROCK (ORIGINALLY A GRANODIORITE OR MONZONITE), STRONGLY LINEATED NOW WITH FAIR AMOUNTS OF CHLORITE. UPPER WORKINGS WERE STARTED ON A MILKY WHITE FE-STAINED QUARTZ VEIN ABOUT 6 INCHES WIDE. LOWER ADIT WAS PROBABLY DRIVEN TO INTERSECT THIS VEIN, BUT DIDN'T MAKE IT!
