The Lewis River is a gold mine located in Alaska.
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 (Workings): PLACER MINING WAS ACTIVE MOSTLY BEFORE 1918. DRILLING FOR POSSIBLE DREDGING WAS DONE IN THE EARLY 1900'S. BEDROCK IS 12 TO 22 FEET BELOW SURFACE.
Comment (Production): ACCORDING TO BROOKS (1918, P. 45-47), SEVEN SMALL PLACER OPERATIONS OPERATED IN 1916 IN THE CANYON BETWEEN UPPER BASIN AND THE FLATS AND PRODUCED OVER $2,000 IN GOLD (WORTH $18.66 AN OUNCE). ONE $2 NUGGET WAS FOUND. UNKNOWN BUT PROBABLY SMALL AMOUNT OF GOLD RECOVERED IN 1956-57 (COBB, 1973, B 1374, P. 17).
Comment (Exploration): Status = Probably inactive
Comment (Location): MACKEVETT AND HOLLOWAY (1977, LOCALITY 9) DESCRIBE MINED AREAS EXTENDING THREE TO SIX MILES DOWNSTREAM FROM THE LANDING STRIP LOCATED NEAR THE HEAD OF LEWIS RIVER ON THE WEST SIDE OF MT. SUSITNA IN T. 14, 15 AND 16 N., R. 9 W. (U.S. BUREAU OF MINES, 1998, MAS # 0020840026; COBB, 1972, MF 385, LOCALITY 9; AND U.S. BUREAU OF MINES, 1973).

SUSITNA. STREAM GRAVEL CARRY COARSE ANGULAR GOLD WITH ATTACHED QUARTZ. COBB (1979, OFR 80-86, P. 17-18) REPORTS THAT GOLD IS PROBABLY DERIVED FROM QUARTZ VEINS IN LOCAL JURASSIC OR CRETACEOUS GRANITIC BEDROCK OR FROM REWORKED TERTIARY CONGLOMERATE. DRILLING FOR POSSIBLE DREDGING WAS DONE IN THE EARLY 1900'S. PLACER MINING WAS ACTIVE MOSTLY BEFORE 1918. BEDROCK IS 12 TO 22 FEET BELOW SURFACE.
