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 (Deposit): THIS SITE NAME WAS CREATED BY THE REPORTER OR OTHER USGS EMPLOYEE BASED ON PROXIMITY TO SOME MAJOR GEOGRAPHIC FEATURE.

Comment (Geology): CREEK FLOWS NEAR THE PROBABLY FAULTED CONTACT BETWEEN PALEOZOIC RECRYSTALLIZED CARBONATE ROCKS AND MESOZOIC ANDESITIC VOLCANIC ROCKS THAT WERE INTRUDED BY SMALL MAFIC AND ULTRAMAFIC PLUTONS. AREA NOT GLACIATED. ; MAJOR.UNITS: BEDROCK IS METAMORPHOSED ANDESITE IN SOME CREEK CLAIMS OLDER SLATE AND LIMESTONE WEST OF CREEK. ; REG.COM: PLATINUM DERIVED EITHER FROM ANDESITIC VOLCANICS OR FROM MAFIC OR ULTRAMAFIC BODIES INTRUDED INTO THEM.

Comment (Deposit): STREAM GRADIENT APPROXIMATELY 50 FEET PER MILE. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT

Comment (Deposit): GOLD MAINLY ON BEDORCK, SOME IN LOWER 2-3 FEET OF GRAVEL. ON CREK CLAIMS ALLUNVIUM THICKNESS RANGES FROM 10 TO 30 FT.; BENCH CLAIMS ABOUT THE SAME. AT LOWER END OF CREEK 1 OZ. PT PER 250 OZ. AU. ON UPPER CLAIMS THERE MAY HAVE BEEN AS MUCH AS 1 OZ. PT PER 100 OZ. AU.

Comment (Workings): ALL THE GROUND WORKED WAS FROZEN.

Comment (Location): USGS MF-389, LOC. 45. GOLD MINE MARKED ADJACENT TO HAYCOCK ON CANDLE (A-5). LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).

Comment (Production): MINING ON 3 CLAIMS YIELDED ABOUT 150 OUNCES IN 1915. IT HAS BEEN ESTIMATED THAT THE PRODUCTION OF 1916 WAS ABOUT 5,000 OUNCES. PRODUCTION FROM WINTER AND SUMMER OPREATIONS IN 1917 TOTALED 7,500 OUNCES. IN 1917, 35 OUNCES OF PLATINUM WERE PRODUCED. MOST OF THE 56 OUNCES OF PLATINUM RECOVERED ON THE SEWARD PENINSULA IN 1918 CAME FROM DIME CREEK.

Comment (Development): FIRST CLAIMS STAKED IN 1910 BY SAM SMITH. PROSPECT HOLES SUNK ON LOWER CLAIMS DID NOT WARRANT FURTHER OPERAITONS AND THE CLAIMS WERE ABANDONED. GOLD DISCOVERRED ON APRIL 4, 1915, AT THE MOUTH OF LITTLE ELDORADO CREEK; FOLLOWED BY A STAMPEDE TO THE CREEK. GOLD PLACERS MINED FROM 1915 TO 1952. MOST OF MINING WAS BY DRIFTING AND OPEN-CUT METHODS; A SMALL DREDGE OPERATED 1923-31 AND 1934-40.
