Ore body information

  • General form TABULAR, IRREGULAR, CRUDELY BANDED
    Dip 45N
    Width 2.13M

Controls for ore emplacement

  • Contact Of Aplite Dikes And Limestone, Limestone Near Faults

Comments on the geologic information

  • ALTERATION & MINERALIZATION ARE IN BOTH LIMESTONE AND QUARTZ PORPH YRY. THE LIMESTONE IS SILICATED & SEEMS TO CARRY MOST OF THE SULFIDES. THE QUARTZ PORPHYRY IS CUT BY PYRITE VEINLETS. PYRITIC ALTERATION IS DISSEMINATED ERRATICALLY IN THE GENERAL AREA. NOT MUCH SERICITE & ONLY OCCURS IN QUARTZ PORPHYRY. CHALCOPYRITE APPEARS INTEROGINOUS WITH HEM ATITE. UNCERTAIN IF HEMATITE IS AFTER MAGNETITE
