Comments on the geologic information

  • MIDDLE SECTION OF DOME CREEK HAS A LOWER GRADIENT THAN PARTS UPSTREAM AND DOWNSTREAM. ; MAJOR.UNITS: BEDROCK IS SCHIST AND CRYSTALINE LIMESTONE CUT BY QUARTZ VEINS. ; REG.COM: SOURCE OF GOLD THOUGHT TO BE GOLD BEARING QUARTZ VEINS CUTTING SCHIST. PRESENCE OF SOME FINE GOLD THROUGHOUT GRAVEL SUGGESTS GOLD MAY HAVE TRAVELED A CONSIDERABLE DISTANCE FROM ITS BEDROCK SOURCE.

Deposit GOLD MAINLY NEAR OR ON BEDROCK BENCH, BUT SOME FINE GOLD THROUGHOUT BENCH GRAVEL, AS MUCH AS 80 FEET THICK. BENCH EXTENDS 4 MILES UPSTREAM AND AT LEAST 2 MILES DOWNSTREAM FROM LITTLE MILLER CREEK; MOST OF MINING DOWNSTREAM FROM LITTLE MILLER CREEK, BECAUSE GRAVEL INCREASES IN THICKNESS UPSTREAM. BENCH ALONG NORTH WALL OF VALLEY APPROXIMATELY 1,200 FEET FROM THE CREEK AND 125 FEET VERTICALLY ABOVE. A LITTLE GOLD WAS RECOVERED FROM DOME CR. IMMEDIATELY BELOW THE MOUTH OF LITTLE MILLER CR.; ALL OTHER PRODUCTION FROM THE BENCH.
