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): BEST LOCATION: USGS I-749; PLACERED AREA ON LOWER 1 MI OF STREAM COURSE AND ON TRIBUTARIES ALONG THIS SECTION LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).

Comment (Production): PLACER MINE ON LITTLE ELDORADO CREEK WAS MAJOR PRODUCER FOR CHISANA DISTRICT IN THE YEARS 1929 THROUGH 1932; TOTAL PRODUCTION FOR THE CHISANA DISTRICT HAS BEEN IN THE 40 TO 50 THOUSAND OZ RANGE

Comment (Development): MINING METHODS: SIMPLE HYDRAULIC AND HAND METHODS ONLY; MAJOR YEARS OF PRODUCTION WERE BETWEEN 1913 AND 1940; SOME SMALL SCALE MINING TO PRESENT TIME, BUT PRODUCTION SINCE 1940 HAS BEEN INSIGNIFICANT

Comment (Deposit): TWO STREAM PLACERS DESCRIBED IN USGS BULL 622: CLAIM NO. 2, 75 TO 150 FT WIDE WITH AVE 3 FT GRAVEL, WIDTH OF PAY STREAK 36 TO 40 FT, AU IN TOP 5 TO 12 IN OF RIPPABLE BEDROCK; CLAIM NO. 3, DIMENSIONS 65 BY 50 FT, DEPTH OF GRAVEL AVE 3 FT, AU ON FALSE CLAY BEDROCK UNDERLAIN BY 2 FT OF GRAVEL, USGS BULL 622, P. 216-217

Comment (Workings): SOME OF THE GRAVEL MINED WAS FROZEN; STREAM GRAVELS WERE REPORTED TO BE "WORKED OUT" BY 1914, WHEN ATTENTION TURNED TO BENCHES AND OLD CHANNELS

Comment (Geology): UPPER COURSE OF STREAM UNDERLAIN BY JURASSIC AND CRETACEOUS ARGILLITE AND MUDSTONE, LOWER COURSE UNDERLAIN BY PYRODASTICS OF THE CRETACEOUS CHISANA FORMATION. ; MAJOR.UNITS: CRETACEOUS CHISANA FORMATION, MAINLY PYROCLASTICS AND LAVA FLOWS ; REG.COM: TERTIARY GRAVELS CAPPING GOLD HILL, THE MOUNTAIN TO THE WEST OF THE BONANZA CREEK DRAINAGE

Comment (Deposit): SEE ALSO: BOULDER CREEK, BOULDER CREEK AND LITTLE ELDORADO CREEK WERE MAJOR PRODUCERS OF THE DISTRICT ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
