Deposit TUNGSTEN OCCURS IN THE COMBINED METALS MEMBER A FEW TENS OF FEET ABOVE THE BASE OF THE PIOCHE SHALE. AG-AU MINERALIZATION OCCURS ALONG THE MAJOR FAULT SYSTEM STRIKING N40W NEAR ITS JUNCTION WITH A N-TRENDING FRACTURE. SILVER BROMIDES AND CHLORIDES OCCUR IN AN AREA OF RECRYSTALLIZED GRAY LIMESTONE 60 FT LONG AND 30 FT WIDE, WITH MINOR GOLD. ABOUT 300 FT E OF THIS AREA, TUNGSTEN MINERALIZATION OCCURS IN AN AREA 300 FT LONG AND 100 FT WIDE WHERE THE LIMESTONE HAS BEEN CRUSHED ADJACENT TO FRACTURES. IN THE CRUSHED ZONES THE FRACTURES HAVE BEEN FILLED WITH LIMONITE,QUARTZ, CALCITE, FELDSPAR, AND SCHEELITE.
