Economic information about the deposit and operations

Development status Prospect
Commodity type Metallic
Deposit size Small
Significant No

Mining district

District name Comet District

Ownership information

  • Type Owner
    Owner Nerco Exploration Co.
    First year 1983

Comments on the workings information

  • 2 SHORT ADITS INCLINED TO EAST; BULLDOZER ROADS AND TRENCHES. ADITS ARE 90 AND 20 FT LONG.

Comments on development

  • ON SMALL POINT BELOW ADITS, SURFACE EXPLORATION WORK HAS BEEN DONE 2-5 YRS AGO (BULLDOZING AND TRENCHING). AN OLD TIMBER STRUCTURE LIES IN FRONT OF THE ADITS (1983). AREA IS CURRENTLY PART OF NERCO CLAIMS, WHICH EXTEND FOR 5 MILES ALONG WEST FLANK OF RANGE AND ARE APPROXIMATELY 1 MILE WIDE (KERR-MCGEE CLAIMS ADJOIN THESE TO THE NORTH). AT TIME OF EXAMINATION, (AUG, 1983) NERCO HAD SEVERAL PEOPLE ON THE PROPERTY INCLUDING CONSULTANTS WHO WERE DOING UNDERGROUND MAPPING AND SAMPLING. CURRENT WORK ALSO INCLUDES ASSESSMENT BULLDOZER WORK.

General comments

Subject category Comment text
Deposit ADITS ARE INCLINED ALONG BEDDING. REPLACEMENT ORE ON DUMP CONSISTS OF A MARLY ORANGE-BROWN ALTERED LIMESTONE CONTAINING PODS AND CRYSTALS OF GALENA, YELLOW SPHALERITE, CHALCOPYRITE, PYRITE. WHITE CALCITE OCCURS IN LENSES AND BLEBS IN HOST ALSO; THE ROCK IS NOT SILICIFIED, BUT CONTAINS ABUNDANT MN DENDRITES IN ADDITION TO PODS AND CLOTS OF SIDERITE AND FE OXIDES, SOME OF WHICH FORM GOSSANY BOXWORKS WITH GALENA CORES. GALENA IS THE MOST ABUNDANT SULFIDE AND TOGETHER WITH SPMALERITE IT HAS REPLACED OOVOID ALGAL FOSSIL REMNANTS IN SOME SAMPLES; IE. THE ORIGINAL TEXTURE OF THE MOST ROCK WAS PARTIALLY PRESERVED IN THE MINERALIZATION PROCESS. SOME MASSIVE WHITE VEINING IS POSSIBLY SMITHSONITE. ALSO YELLOW PLUMBOJAROSITE (?) COATINGS AND CU OX (MALACHITE) HAVE DORMED AFER GLENA AND CHALCOPYRITE.
