Ore body information

  • General form LENSES, VEINS
    Length 304.8M

Comments on the geologic information

  • NEAR THE IRON DEPOSIT THE DOLOMITE STRIKES N50E AND DIPS 60NW. IT IS COMPLEXLY FOLDED AND FAULTED. THE ROCKS HAVE BEEN CUT AND METAMORPHOSED BY GRANITIC ROCKS, THE NEAREST EXPOSURE LESS THAN 300 FEET FROM THE DEPOSIT. THE IRON ORE IS BELIEVED TO BE RELATED TO THE GRANITIC ROCKS. ADJACENT TO THE GRANITIC CONTACT, THE LIMESTONE HAS BEEN ALTERED TO A NARROW ZONE OF TACTITE EXPOSED IN OUTCROP FOR DISTANCE OF 400 FEET. IN THIS ALTERED ZONE SCHEELITE MINERALIZATION OCCURS ASSOCIATED WITH GARNET, EPIDOTE, QUARTZ, AND MINOR PYRITE FINELY DISSEMINATED IN SHOOTS 3 TO 6 FEET WIDE AT MINOR FAULT INTERSECTIONS.
