Ore body information

  • Strike N75E
    Dip 80 NW
    Thickness 1.52M

Comments on the geologic information

  • ROCK IS LOCALLY CUT BY RANDOM CALCITE VEINLETS AND STAINED BY MINOR FE OXIDES. WALLROCKS ARE RELATIVELY UNALTERED AND SHOW ONLY RECRYSTALLIZATION AND IRON-STAINING AS ALTERATION EFFECTS. LIMESTONE HERE STRIKES ABOUT N-5 AND DIPS GENTLY E. AT THE SHAFT. THE LIMESTONE FORMS BEDS ABOUT 0.5-2.0 FT THICK. ALTERED ZONE OUTCROPS JUST E OF SHAFT COLLAR. ALTERED ROCK IS PUNKY IN TEXTURE, SOMEWHAT SILICIFIED, STAINED AND REPLACED BY ABUNDANT LIMONITE (PLUMBOJAROSITE?) AND MN OXIDES CALCITE OCCURS IN VUGS, AND MINOR QUARTZ VEINING IS EVIDENT.

Significant No

Mining district

District name Comet District

Comments on the workings information

  • VERTICAL SHAFT APPROX. 30-50 FT DEEP, WITH METAL PIPE AND LADDER EXTENDING TO DEPTH TRENCHING IN AREA OF SHAFT IS ABOUT 5 YEARS OLD. MORE RECENT EXTENSIVE TRENCHING ON OTHER SIDE OF CANYON TO NORTH.

Comments on development

  • AT TIME OF EXAMINATION IN AUG., 1983, SHAFT HAD BEEN ROPED OFF AND FLAGGED WITHIN THE PAST FEW WEEKS INDICATING RECENT SAMPLING OR EXAMINATION OF THE WORKINGS.
