Controls for ore emplacement

  • Lode Source To Se Of Creek; Auriferous Channels Enter Old Bench Channel From The Se.

Comments on the geologic information

  • VALLEY ASSYMMETRIC; STEEP SOUTH SIDE ALONG WHICH STREAM FLOWS AND GENTLY SLOPING NORTH SIDE; BENCHES ON BOTH SIDES. BURRIED CHANNEL MINED ON BENCH ON NORTH SIDE. THIS CHANNEL IS SEPERATED FROM THE PRESENT CHANNEL OF LIVENGOOD CR. BY A BEDROCK REEF, TRACABLE FROM LIVENGOOD TO THE MOUTH OF AMY CREEK. SOME OF HEADWATER TRIBUTARIES WERE PIRATED FROM THE SO. FORK OF HESS CREEK. GRADIENT OF OLD BURRIED CHANNEL MUCH STEEPER DOWN VALLEY THAN NEAR HEAD; ABRUPT CHANGE IN GRADIENT. DIVIDE BETWEEN LIVENGOOD AND HESS CREEKS SHIFTED BACK AND FORTH AS A RESULT OF SUCCESSIVE STREAM PIRACIES. ; MAJOR.UNITS: BEDROCK IS MAINLY CHERT, SILICIFIED LIMESTONE/DOLOMITE, AND GREENSTONE. BEDROCK DEEPLY WEATHERED, LOCALLY MUCH BRECCIATED DARK-GRAY TO BLACK FLINT OR CHERT WITH PYRITE.

    First year 1975

Comments on the workings information

  • MINED MAINLY BY DRIFTING. SHAFTS SUNK TO BEDROCK AND TUNNELS ARE DRIVEN IN TWO DIRECTIONS FROM THE BOTTOM OF THE SHAFT, ALONG THE LINE OF THE PAY STREAK. FROM THE ENDS OF THE TWO TUNNELS CROSSCUTS ARE MADE TO THE LATERAL LIMITS OF THE AURIFEROUS GRAVEL, BLOCKING OUT WORKABLE GROUND. GRAVEL IS REMOVED BY A RETREATING LONG-WALL SYSTEM, WORKING TOWARD THE SHAFT. EXCELLENT CONDITIONS FOR DRIFTING.

Comments on development

  • PLACER MINED BY DRIFT AND OPEN-CUT METHODS BETWEEN 1914 AND 1977, WITH PROBABLY A FEW INACTIVE YEARS. TWENTY-ONE PLANTS AT WORK DURING THE SUMMER OF 1916. LOWER PART OF CREEK DREDGED 1940-41 AND 1946 TO ABOUT 1950. LARGE-SCALE MINING UNDERWAY IN 1976-1977. ESTIMATED RESERVES FROM 640 DRILL HOLES INDICATES ABOUT 17 MILLION CUBIC YARDS OF PLACER GRAVEL THAT WOULD YEILD ABOUT .02 OZ/YD3 GOLD.

General comments

Subject category Comment text
Deposit MOST OF GOLD IN BASAL GRAVEL, ON BEDROCK, AND IN CRACKS OF WEATHERED BEDROCK IN AN OLD CHANNEL UNDER BENCH PARALLEL TO AND ONE HALF MILE NW OF CREEK. THE BENCH CHANNEL HAS A LINEAR EXTENT OF AT LEAST 4 MILES, AN AVERAGE WIDTH OF ABOUT 125 FT., AND AN AVERAGE DEPTH TO BEDROCK OF ABOUT 80 FT. GRAVEL AVERAGES 14 FT. IN THICKNESS; OVERLAIN BY MUCK, SILT, AND SAND. ABRUPT CHANGE IN GRADIENT OF CHANNEL; BELOW BREAK PAY STREAK IS 75-180 FT. WIDE; ABOVE IT IS 100-364 FT. WIDE. UP TO 5 FT. OF GRAVEL AND 2.5 FT. OF BEDROCK MINED. GOLD IN PRESENT STREAM GRAVELS, BUT PLACERS LESS RICH THAN IN OLD CHANNEL.
Deposit STREAM GRADIENT ABOUT 50 FT. PER MILE. LIVENGOOD CREEK HAS BEEN THE LARGEST PLACER GOLD PRODUCER IN THE TOLOVANA DISTRICT; PROBABLY ACCOUNTED FOR AT LEAST HALF OF THE 330,000 FINE OZ. ATTRIBUTED TO THE ENTIRE DISTRICT. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
