Ore body information

  • General form TABULAR, PODS, IRREGULAR
    Thickness 9.14M
    Length 30.48M
    Width 30.48M

Controls for ore emplacement

  • The Relatively Large Size And High Tenor Of The Orebody Is Due To Its Situation At The Junction Of The Two Lodes (The Clarklode, And The Gold Dome Lode), Where The Rocks Have Been More Extensely Fractured Than Elsewhere. The Mineralization Is At Or Near The Contact With The Augusta Limestone. (Schrader)

Comments on the geologic information

  • THE GOLD ORE BODIES RANGE IN SIZE FROM SMALL PODS TO LARGE IRREGULAR MASSES SEVERAL HUNDRED FEET IN STRIKE & DIP LENGTHS AND UP TO 30 FT. THICK. MOST OREBODIES ARE ALONG NORTH TRENDING, VERTICLE FRACTURE ZONES. THE DEPOSITS CONSIST OF FREE GOLD WITH QUARTZ, OPALITE, IRON OXIDES, JASPER, AND CALCITE IN HIGHLY ALTERRED DIORITE. WHERE DIORITE INTRUDES LIMESTONE TACTITE HAS FORMED CO/GARNET, EPIDOTE,& NONTRONITE PRESENT. SAMPLES ASSAYED FOR TUNGSTER REVEALED NONE (VANDERBURG) MUCH OF THE HIGH GRADE ORE WAS PRESENT IN A GANGUE OF LIGHT GREY TO WHITE, VERY FINELY POROUS, HONEYCOMBED OPAL VERY SIMILAR IN APPEARANCE TO SILICEOUS SINTER.
