| Deposit | SCHEELITE OCCURS IN PYROXENE-RICH SKARN CONSISTING LARGELY OF GARNET AND QUARTZ WITH MINOR SCHEELITE AND SOME MOLYBDENITE. SCHEELITE GRAINS ARE RATHER SMALL IN SIZE. MOST TACTITE CONTAINS LESS THAN 0.5% WO3, WITH THIN LAYERS OF ABOUT 1.0% W03. SAMPLE 2894 WAS SELECTED FROM THE DUMPS AND SKARN ZONE - POSSIBLE TUNGSTEN IN THE SEDIMENTS AND UNIDENTIFIED SULFIDES IN QUARTZ VEINS AND SHEARS. SAMPLE 2895 WAS TAKEN FROM THE OPEN PIT WHERE AN EXPOSED SHEAR CONTAINED GOSSAN-LIKE IRON-STAINING IN ASSOCIATION WITH PYRITE AND OTHER SULFIDES. ROCK ON THE DUMP OF ONE OF THE NW SHAFTS IS AN UNUSUAL VARIETY OF TACTITE COMPOSED MAINLY OF DARK GREEN PYROXENE WITH SOME GARNET AND SPECKS OF SCHEELITE AND MOLYBDENITE. |
