Comments on the workings information

  • BAR DEPOSIT WORKED BOTH BY GROUND SLUICING AND BY DRYLAND WASHING PLANT. SEVERAL PRESUMABLY EXPLORATORY SHALLOW SHAFTS

Comments on development

  • JAMES GOOLDY, WHO HAD BEEN INVOLVED IN DISTRICT'S DEVELOPMENT SINCE 1894, WAS GENERAL MANAGER OF TIMBERLAKE MINING AND DEVELOPMENT CO. ABOUT 1903, HE AND COMPANY DIVERTED WATER FROM SLATER CREEK THRU 7.5-MILE DITCH TO WILLOW CREEK, WHERE IT JOINED B.W. LAW'S DITCH, THEN ACROSS TO FOURMILE CREEK, DOWN ITS CHANNEL FOR 3 MILES, THEN BY PIPE FOR OVER 5 MILES ACROSS MUD SPRING CULCH, THEN BY DITCH ANOTHER 7 MILES TO COMPANY'S PROPERTY ON TIMBERLAKE CREEK. GOOLDY USED WASTEWATER FROM TMDC PROPERTY UPSTREAM FOR GROUND SLUICING AT GOOLDY PLACER. VALUES OF GROUND WORKED RANGED FROM $0.25 TO $0.41/YD. ACCORDING TO MARKS (1915), RECOVERY IN LATER YEARS WAS ESTIMATED AT $700 IN 1913, $2475 IN 1914, $1675 IN 1915.

Deposit FARNSWORTH'S OROGINAL DESCRIPTION STATED THAT THE HIGHER PAYING ZONES IN AREA LIE IN SLIGHTLY CONSOLIDATED GRAVELS BENEATH IRON OXIDE-CEMENTED CONGLOMERATE AND ABOVE LAYER OF "BLUE CLAY," (NOW INTERPRETED AS EOCENE BEDROCK). AU CONCENTRATIONS IN TERRACE AND MANTLE DEPOSITS APPEART LIMITED TO LEVEL BELOW THE PROMINENT CONGLOMERATE OR "CAP ROCK," WHICH WAS INTERPRETED BY PARKER (1974) AND THEOBALD AS A DELTAIC FAN IN EITHER THE TIPTON TONGUE OF GREEN FIVER FM (EOCENE) OR CATHEDRAL BLUFFS MEMBER OF WASATCH FM (EOCENE). MODERN PLACERS THUS WERE DERIVED FROM EOCENE FOSSIL BEACH AND ALLUVIAL PLACERS AND PROBABLY BEGAN FORMING IN LATE PLIOCENE OR PLEISTOCENE TIME. AGE OF MINERALIZATION CITED FOR DEPOSIT DEPENDS ON UNIT WORKED--EOCENE FOR BEDROCK OPERATIONS OR QUATERNARY FOR TERRACE, STREAM BED, AND MANTLE OPERATIONS. THE GOOLDY PLACER DEPOSIT IS A BAR OR TERRACE-FAN COMPLEX AT CONFLUENCE OF EAST AND WEST TIMBERLAKE CREEKS AND 20 TO 30 FT ABOVE STREAM LEVEL. ELDORADO MINING CO. PORTION WORKED
Deposit TOP 5 TO 10 FT OF DEPOSIT. GOOLDY MINED REST OF DEPOSIT TO DEPTH OF 4 FT WHERE HE ENCOUNTERED CLAY LAYER. AU-BEARING GRAVELS WERE FOUND BELOW CLAY IN SEVERAL SHALLOW SHAFTS. DEPOSIT AND AU ARE OF D
