Comments on the geologic information

  • ROCKS IN AREA ARE CHIEFLY ANDESITES, BASALTS, AND TUFFS INTERBEDDED WITH A NEARLY VERTICAL STRATUM OF LIMESTONE THAT STRIKES NE AND HAS A MAXIMUM THICKNESS OF 500 FEET THESE FORMATIONS HAVE BEEN INTRUDED BY GRANITIC STOCK, DIKES AND SILLS. IN THE VICINITY OF THE MINE SHAFT A PRE-GRANITE FAULT, STRIKING NW AND DIPPING 30-40DEGREES NE HAS BROKEN THE LIMESTONE DIPLACING THE NORTHEAST PORTION 350 FEET NORTHWEST: THIS FAULT LOCALLY CONTROLLED THE EMPLACEMENT OF THE GRANITE. POST-GRANITE FAULTS ARE WELL EXPOSED IN THE UNDERGROUND WORKINGS WHERE THEY ARE MAINLY RESTRICTED TO THE LIMESTONE-GRANITE CONTACT. ADJACENT TO THE GRANITE CONTACTS, LIMESTONE HAS BEEN ALTERED TO TACTITE IN ZONES VARYING FROM 15 TO 50 FEET WIDE. IN SOME PLACES, HORNFELS UP TO 40 FEET THICKNESS SEPARATE THE LIMESTONE FROM GRANITE PREVENTING THE ALTERATION OF THE LIMESTONE TO TACTITE. SCHEELITE MINERALIZATION OCCURS WITH GARNET, EPIDOTE, DROPSIDE, QUARTZ, CALCITE, LIMONITE AND CU-CARBONATES. PYRITE IS LOCALLY ABUNDANT,
  • AND IN SOME PLACES SMALL AMOUNTS OF CHALCOPYRITE OCCUR.

General comments

Subject category Comment text
Deposit THE ORE-BEARING TACTITE ZONES HAVE BEEN WELL-OXIDIZED TO THE 200 FOOT LEVEL, AND TO LOWER LEVELS IN AREAS CRUSHED BY POST-MINERAL FAULTS. LIMONITE IS PRINCIPAL OXIDE MINERAL. LOCALLY TACTITE CONTAINS SEVERAL PERCENT OF W03 IN FORM OF FERRITUNGSTITE (?). SCHEELITE IS IN FORM OF SMALL CRYSTALS FROM SIZE OF PINHEAD UP TO 1/2 INCH IN DIAMETER. IN PLACES THE TACTITTE IS STAINED WITH COPPER. TACTITE ZONE IS 2 TO 50 FT WIDE.
