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.

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.

Comment (Development): NO RECORD OF PRODUCTION, THOUGH THERE MAY HAVE BEEN SOME.
Comment (Deposit): SMALL BROOK FLOWING OVER MUSKEG HAS UP TO 8 FT. OF PEAT AND MUCK COVERING ANGULAR FRAGMENTS OF GRAYWACKE. GRAYWACKE BEDROCK IS HARD AND IRREGULAR. DEPOSIT IS ELUVIAL, AS SHOWN BY ANGULARITY OF ROCK AND GOLD.
