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 (Location): LOCATION IS NUGGET BENCH HIGH CHANNEL DEPOSIT, USBM OFR 24-78, FIG. 4.2-B(3) LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).
Comment (Geology): GEOL.COM: NUGGET BENCH HIGH CHANNEL IS CUT INTO ARGILLITE OF JURASSIC TO CRETACEOUS AGE; CHANNEL CAN BE PROJECTED BY MAGNETIC METHODS 400 FT BEYOND MINED SECTION ; MAJOR.UNITS: STREAM HEADS IN MESOZOIC SLATES AND GRAYWACKES CONTAINING AURIFEROUS VEIN QUARTZ; LOWER COURSE IN TERTIARY CONTINENTAL ROCKS OF KENAI GROUP. UPPER MEMBER OF KENAI FORMATION IS PREDOMINATELY A SANDY CONGLOMERATE OF WELL ROUNDED, WELL INDURATED COBBLES 2 TO 6 IN IN DIAMETER COMPOSED OF BLACK SILTSTONE, QUARTZ, QUARTZ MONZONITE, GRAYWACKE AND GREENISH WHITE FELDSPAR PORPHYRY; MINOR SILTY SANDSTONE WITH SEAMS OF CLAYSTONE AND SPARSE LENSES OF CONGLOMERATE.
Comment (Workings): NUGGET BENCH CHANNEL HAS BEEN MINED FOR 1000 FT ALONG A NE-SW TREND ACROSS NUGGET CREEK, CHANNEL SLOPES AWAY FROM PRESENT DRAINAGE DIRECTION, SO BEDROCK DRAINS HAVE BEEN CUT TO NUGGET CREEK
Comment (Production): 30,000 OZ AU PRODUCED FROM 1000 FT SECTION MINED ALONG NUGGET BENCH CHANNEL, USBM OFR 24-78, P. 4-114
Comment (Development): HYDRAULIC MINING HAS BEEN USED ON ELEVATED BENCH GRAVELS
Comment (Deposit): AVRIFEROUS STREAM GRAVELS 6 TO 8 FT DEEP; BENCH GRAVELS 1 TO 6 FT DEEP; UPPER CONGLOMERATIC UNIT OF KENAI FORMATION HAS BEEN MINED AT NUGGET BENCH HIGH CHANNEL, NE 1/4, SEC. 16, T. 28 N., R. 9 W., USGS OFR 311, P. 11
Comment (Deposit): BOTH QUATERNARY GLACIOFLUVIAL DEPOSITS AND TERTIARY CONGLOMERATIC UNITS HAVE BEEN MINED ON NUGGET CREEK; SEE ALSO: CACHE CREEK; GLACIOFLUVIAL DEPOSITS SIMILAR TO NUGGET CREEK CAN BE FOUND ON WINDY CREEK AND BIRD CREEK ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
