Economic information

Ore body information

  • General form PINCH AND SWELL
    Strike NORTH-SOUTH
    Dip STEEPLY EAST

Controls for ore emplacement

  • Mineralized Solutions Emanating From Shallow Intrusive Rocks Were Localized Along Shale-Porphyry Contacts And Fissures And Fractures Associated With Contemporaneous Faulting.

Comments on the geologic information

  • MOLYBDENUM MINERALIZATION IN THE TUNNEL IS SPARSELY DISTRIBUTED AND OCCURS AS COATINGS AND STRINGERS IN QUARTZ-PYRITE VEINS WHOSE AVERAGE WIDTH IS TWO INCHES. MOST VEINS STRIKE NORTH-SOUTH AND DIP STEEPLY EAST, ALTHOUGH VARIATIONS IN BOTHSTRIKE AND DIP OCCUR. MOLYBDENITE OCCURS NEAR THE MIDDLE OF T HE TUNNEL FOR A LENGTH OF 1825 FT. AND A WIDTH OF 800 FT. MOLYBDENITE CROPS OUT ON THE SURFACE IN VEINS AND FLOAT ABOUT 1800 FT. ABOVE THE TUNNEL. THE VEINS ARE REPORTED TO BE NEITHER AS RICH, NOR AS CLOSELY SPACED AS VEINS AT THE QUESTA MOLY MINE.
