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 (Production): TOTAL PRODUCTION TO 1910 ESTIMATED TO HAVE BEEN SEVERAL HUNDRED THOUSAND DOLLARS WORTH, INCLUDING AG, AU, CU, PB, ZN, MO, W.
Comment (Development): WORKED IN 1870'S AND 1880'S; IDLE UNTIL 1905. PRODUCED $25,000 IN 1906-1907.
Comment (Deposit): FISSURE VEIN OF BANDED QUARTZ AND SULFIDES IN GRANODIORITE
Comment (Workings): SHAFT WITH LEVELS AT 60, 115, AND 215 FEET.
Comment (Geology): THE OREBODY IS A FISSURE VEIN OF BANDED QUARTZ AND SULFIDES WHICH STRIKES N70E, AND DIPS 70N. THE COUNTRY ROCK IS A COARSE GRANODIORITE COMPOSED OF OLIGOCLASE, ANDESINE, QUARTZ, HORNBLENDE, AND BIOTITE. (EMMONS 1910). IT INTRUDES CHERT, SHALE, QUARTZITE, AND MINOR CARBONATE UNITS OF THE SILICEOUS WESTERN ASSEMBLAGE PALEOTAC ROCKS, WHICH HAVE BEEN THRUSTED INTO THEIR PRESENT POSITION DURING THE ANTLER OROGENY IN DEVONIAN TIME
Comment (Deposit): THE MINE IS LOCATED NEAR THE SUMMIT OF A GRANITE RIDGE. IT WAS WORKED DURING THE 1870'S & 80'S BEFORE IT LAY IDLE TILL 1905. IT PRODUCED $25,000 IN 1906, 1907. THE MAIN SHAFT IS DOWN 250 FEET WITH LEVELS AT 60, 115, AND 215 FEET DOWN. IN 1908 ONLY THE 60 LEVEL WAS ACCESSIBLE. TOTAL PRODUCTION PRIOR TO 1910 WAS ESTIMATED AT SEVERAL HUNDRED THOUSAND DOLLARS (EMMONS)
Comment (Deposit): Discovery Year: 1870'S
