Deposit GOLD IN BASAL GRAVEL AND IN TOP FEW FEET OF BEDROCK. IN PLACES IT IS NECESSARY TO REMOVE 5 TO 6 FT. OF BEDROCK TO GET A GOOD RECOVERY. PAY STREAK IN BENCHES EXTENDING HALF A MILE OR SO NW OF CREEK. GOLD RECONCENTRATED INTO RICH PLACERS WHERE BENCHES ARE CROSSED BY SMALL TRIBUTARY STREAMS. BENCH GRAVELS ARE 3-12 FT THICK AND ARE MAINLY LOCALLY DERIVED. RICHEST BENCH IS 250 FT. ABOVE AND 2,000 FT. NORTH OF CREEK, LOWER BENCHES ARE LOWER GRADE.
Deposit STREAM GRADIENT ABOUT 80 FT. PER MILE. LOCATION DESCRIPTION FOR PIONEER CR. AND ALL TRIBUBARIES ENTERING FROM THE NW. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
