| Deposit | THE CONTACT OF SEDIMENTS WITH THE QUARTZ MONZONITE PLUTON DIPS 30-70S AND CUTS ACROSS BEDS AT A SMALL ANGLE. NEAR -THE COLLAR OF THE SHAFT THE CONTACT BENDS ACROSS THE STRIKE OF- THE BEDS CUTTING OUT THE MARBLE EASTWARD. TACTITE OCCURS ALON-G THE MARBLE/QUARTZ MONZONITE CONTACT. SCHEELITE OCCURS IN THE- TACTITE ALONG WITH QUARTZ, GARNET, DIOPSIDE, EPIDOTE, AND HOR-NBLENDE. ALMOST ALL THE TACTITE WAS TUNGSTEN ORE, BUT TACTITE -WAS PRESENT ALONG ONLY A SMALL PART OF THE CONTACT. BELOW THE -5TH LEVEL, SOME OF THE TACTITE IS RICH IN FLUORITE AND CONTAIN-S PODS OF SPHALERITE WITH A LITTLE PYRITE, GALENA AND CHALCOPY-RITE. IN THE UPPER PORTION OF THE MINE, THE TACTITE IS OXIDIZE-D TO A POROUS, FRIABLE AGGREGATE OF QUARTZ, IRON OXIDES, AND S-CHEELITE, AND THE HEAVY SILICATE MINERALS ARE ALMOST LACKING. -THE MAIN OREBODY EXTENDS WEST FROM THE BEND IN THE CONTACT NEA-R THE SHAFT FOR ABOUT 225 FT AT THE SURFACE AND BECOMES SHORTE-R WITH DEPTH. THE ORE WAS 1-15 FT WIDE IN UPPER LEVELS BUT BEL-OW |
| Deposit | THE 5TH LEVEL THE OREBODY IS A NARROW PIPE 2-5 FT WIDE AND -20 FT LONG. WHERE THE OREBODY IS LONGEST AND THICKEST, THE CON-TACT HAS THE FLATTEST DIP. THE SMALL LENSES OF ORE EXPOSED WES-T OF THE MAIN ORE BODY ARE NARROW AND APPEAR TO BE SHALLOW. TH-E AVERAGE GRADE OF THE ORE MINED WAS ABOUT 1.35 % WO3. CURRENT-LY (1985) ALL OF THE STOPES WHICH DAYLIGHT AT SURFACE ALONG TH-E CONTACT DISPLAY VERY LITTLE SKARN (DARK SILICATE) ZONE. THE -OUTCROP OF THE CONTACT SILICATE ZONE IS MARKED BY PODS OF WHIT-E QUARTZ; PILLARS REMAINING IN THE STOPES ARE LARGELY QUARTZ W-ITH A THIN LAYER (6 IN TO 2 FT) OF PALE SILICATE ROCK OCCUPYIN-G THE CONTACT BETWEEN GRANODIORITE AND COARSELY CRYSTALLINE MA-RBLE. THE ZONE IS STAINED WITH IRON AND MN OXIDES. NO SULFIDES- OF ANY TYPE WERE NOTED. ON THE EASTERN DUMPS, SOME BLOCKS OF -WHITE SILICATED LIMESTONE WITH STRINGS OF SMALL GARNET CRYSTAL-S ALONG BEDDING PLANES. |
