Comments on the ore body information

  • ?UPGRADING AND THICKENING OF ORE IN SPECIFIC STRUCTURALLY CONTROLLED SITES. CONTROVERSY REMAINS WHETHER THE BIOTITE SCHIST HOSTED QUARTZ ORE IS A REFOLDED PRIMARY STRATABOUND DEPOSIT, STRUCTURALLY CONTROLLED VEINS FOLDED INTO GROSS CONFORMITY.? (CUTHILL AND OTHERS, 1989)
  • ANTICLINAL FOLDS ALONG WITH HOST ROCK COMPOSITION INFLUENCED FORM, DISTRIBUTION, & TYPE OF DEPOSITION. STOCK GENETICALLY ASSOCIATED WITH ORE-BEARING LODES.

    SULPHIDE MINERALIZATION CONTROLLED BY BEDDING, SCHISTOSITY, CLEAVAGE, TENSION FRACTURES, AND SELVEDGES TO QUARTZ BOUDINS AND VEINS. (CUTHILL AND OTHERS, 1989).

Comments on the geologic information

  • N-TRENDING ANTICLINE WITH WELL DEVELOPED CROSS FOLDING



    ?THE MAJOR FAULTS (100?S OF FEET OF DISPLACEMENT) ON MINERAL HILL ARE THE EAST FAULT AND THE BEAR GULCH FAULT.? (BOTH ARE WEST DIPPING, NORTH TRENDING NORMAL FAULTS (LARAMIDE ?) ARE ALSO NUMEROUS SMALL OFFSET (10?S OF FEET) FAULTS IN THE MINE. ALSO THREE DEFORMATIONAL FOLDING EVENTS WHICH CONTROL ORE DISTRIBUTION (AND POSSIBLY A 4TH). (CUTHILL AND OTHERS, 1989).
  • TWO VEIN TYPES FOUND IN JARDINE LODES. QUARTZ VEINS ARE ASSOCIATED WITH QTZ. SCHISTS & QUARTZITES AND HAVE ERRATIC METAL CONTENTS. ARSENOPYRITE VEINS ASSOC. WITH THE CUMMINGTONITE - HAVE CONSISTENT GOLD CONTENT AND HIGH TENOR.

    ?GOLD MINERALIZATION OCCURS WITHIN AN ARCHEAN PACKAGE OF METATURBIDITES DOMINATED BY QUARTZ-BIOTITE SCHIST, WITH SUBORDINATE BIOTITE SCHST, IRON FORMATION, AND QUARTZ. DIABASE DIKES CROSSCUT THIS PACKAGE. METAMORPHIC GRADE IS GREENSCHIST TO LOWER AMPHIBOLITE FACIES. FOLDED STRATIFORM ORE IS HOSTED BY SULPHIDE-SILICATE FACIES IRON FORMATION, BIOTITE SCHIST, AND QUARTZ. ARSENOPYRITE, PYRRHOTITE, PYRITE, AND SCHEELITE ACCOMPANY THE GOLD MINERALIZATION.? (CUTHILL AND OTHERS, 1989)

    ?THE ORE IS CONFINED TO A SINGLE IRON FORMATION AND ENVELOPING SCHISTS WITH QUARTZ UNITS WITHIN THE JARDINE PACKAGE.? (CUTHILL AND OTHERS, 1989).

General comments

Subject category Comment text
Deposit TVX GOLD PLACED THE MINE ON CARE AND MAINTENANCE 9-96. CORRECTED MINES ID FROM 2401145 TO 2470128.
Deposit Merged data from deposit ID 10270293 (Crevice Mtn. Mine)
Deposit Mineralization is hosted by 3.0 to 3.2 Ga lower amphibolite facies grunerite bearing banded iron formation and meta-turbidites on the Wyoming Craton.



Three types of ore have been mined, namely: 1). The dominant style where Au is contained in marginal wall rock altered envelopes of arsenopyrite, pyrrhotite, hornblende and grunerite sandwiching 0.01 to 1 m thick quartz veins within iron formation, 2). in generally less than 5 m thick banded quartz veins with little or no accompanying wall rock alteration, and 3). in deformed quartz boudins.
