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.

Comment (Deposit): TOTAL HYPOTHETICAL RESOURCE IS 8 SQ MI OF BEACH AREA TOTALING 90 MILLION CUBIC YARDS OF MATERIAL AT AN AVERAGE GRADE OF 1% ILMENITE AND LESS THAN 0.00001 OZ/CY OF GOLD. NO LARGE TONNAGES OF HIGH GRADE PLACER GOLD FOUND IN NEAR-SURFACE BEACH SANDS. ; INFO.SRC : 1 PUB LIT
Comment (Deposit): THIS SITE NAME WAS CREATED BY THE REPORTER OR OTHER USGS EMPLOYEE BASED ON PROXIMITY TO SOME MAJOR GEOGRAPHIC FEATURE.
Comment (Development): DISCOVERED AND MINED BY RUSSIANS BEFORE 1867. FIRST AMERICAN PRODUCTION 1894. WORKED 1894-1917 BY SLUICE AND LONG TOM METHODS. MINOR PRODUCTION UNTIL ABOUT 1940. 105 ACTIVE CLAIMS HELD IN 1978 BY GOLD RESERVE MINING CO..
Comment (Deposit): BEACH SAND DEPOSITS EXTEND FROM MOUTH OF SEA OTTER CREEK SOUTH AT LEAST 20 MI TO MOUTH OF EAGLE CREEK 2 MI NORTH OF LITUYA BAY. ACTIVE BEACH SANDS AVERAGE 500 FT WIDE, BACK BEACH UP TO 1.300 FT WIDE, WITH MARINE TERRACES AT ELEVATIONS UP TO 750 FT IN COASTAL FOOTHILLS. TERRACES ARE UP TO 100 FT THICK. 1-2 IN THICK LAYER OF FINE, GARNET-RICH SAND CARRIES MOST GOLD AND PLATINUM. ESTIMATED RESOURCE OF 1 SQ MI OF BEACH SAND SAMPLED IS 120,000 TONS ILMENITE, AND 1,200 TROY OZ GOLD, WITH ADDITIONAL 7 SQ MI OF BEACH NOT SAMPLED, ACCORDING TO USGS OF 78-494, P.C-30,31.
Comment (Workings): SLUICE BOX AND LONG TOM METHODS USED, SLUICE PLANT OPERATED 1901-1903 AT ECHO CREEK. EXTENSIVELY SAMPLED BY USBM IN 1977.
Comment (Location): USGS MF-436, LOC. 65; USGS OF 78-494, FIG. C-3, 4, 5. LOCATION IS AT MOUTH OF ECHO CREEK, THE SITE OF GREATEST PRODUCTION. DEPOSIT EXTENDS FROM MOUTH OF SEA OTTER CREEK SOUTH 20 MI TO MOUTH OF EAGLE CREEK. LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).
