Comments on the production information

  • TOTAL PRODUCTION IS NOT KNOWN, BUT ABOUT 2850 OZ GOLD WAS REPORTEDLY PRODUCED FROM 1937 TO 1941. A FEW BLOCKS OF UNMINED GROUND REMAIN MID-VALLEY BUT THE CREEK HAS BEEN LARGELY MINED. TWO HUNDRED OUNCES OF GOLD WAS PRODUCED FROM ONE 300 FT BY 150 FT CUT ON THE DISCOVERY CLAIM (EBERLEIN AND OTHERS, 1977, P. 24).

Comments on the workings information

  • PLACER GOLD WAS MINED FROM 1932 TO 1940 AND INTERMITTENTLY FROM 1946 TO 1959. PROSPECTING AND MAINTENANCE WORK OCCURRED IN 1966. THE CREEK HAS LARGELY BEEN MINED OUT BY SURFACE WORKINGS (EBERLEIN AND OTHERS, 1977, P. 24).

General comments

Subject category Comment text
Deposit BEDROCK IN THE AREA IS SCHIST,AND, NEAR THE MOUTH OF THE CREEK A GRANITIC PLUTON (WEDOW AND OTHERS, 1954, P. 8). A SAMPLE OF GRANITE TALUS CONTAINED STIBNITE AND SCHEELITE (NELSON AND OTHERS, 1954). JOESTING (1942) REPORTED STIBNITE IN PLACER CONCENTRATES AND SCARCE CASSITERITE IN PLACERS. PLACER GOLD WAS MINED FROM 1932 TO 1940 AND INTERMITTENTLY FROM 1946 TO 1959. GRAVEL IS TEN TO ELEVEN FEET THICK. PROSPECTING AND MAINTENANCE WORK OCCURRED IN 1966. THE CREEK HAS LARGELY BEEN MINED OUT BY SURFACE WORKINGS (EBERLEIN AND OTHERS, 1977, P. 24). TOTAL PRODUCTION IS NOT KNOWN, BUT ABOUT 2850 OZ GOLD WAS REPORTEDLY PRODUCED FROM 1937 TO 1941. A FEW BLOCKS OF UNMINED GROUND REMAIN MID-VALLEY BUT THE CREEK HAS BEEN LARGELY MINED.
