| Deposit | THE ADITS APPEAR TO EXPLORE ONE OR MORE QUARTZ VEINS IN AN IRON-STAINED, SERICITICALLY ALTERED GRANITE PORPHYRY. THE MINERALIZED ZONE CANNOT BE OBSERVED IN MOST OF THE WORKINGS. THERE APPEARS TO BE A N 15 W, 35 NE QUARTZ VEIN WHICH SEVERAL ADITS EXPLORE. A NEARLY FLAT QUARTZ VEIN WAS OBSERVED IN WORKINGS NEAR THE CANYON BOTTOM, BELOW THE MAINLINE OF ADITS. VEIN MATTER ON THE DUMPS CONTAINS IRON-AND MANGANESE-OXIDE MINERALS, SPARSE GREEN OXIDE COPPER MINERALS, CHALCOCITE?, TETRAHEDRITE?, AND PYRITE. QUITE A LOT OF QUARTZ VEIN MATTER IS PRESENT ON THE DUMPS, BUT THERE WERE FEW ECONOMIC MINERALS OBSERVED. THE VEIN QUARTZ IS WHITE, COMMONLY MASSIVE OR CRUSTIFORM, WITH SPARSE DRUSY AREAS. THE MAIN? VEIN QUARTZ OCCURS NEAR THE INTRUSIVE CONTACT WITH CAMBRIAN PREBLE FM SILTSTONE. THE CONTACT IS EXTENSIVELY SHEARED AND THE PORPHYRY IS LOCALLY SHEARED AND BRECCIATED. THE GRANITE PORPHYRY IS LOCALLY APLITIC. A DIKE OF HORNBLENDE-BEARING, CHLORITIZED GRANODIORITE PORPHYRY WAS ALSO |
| Deposit | NOTED. CHLORITIZATION IS COMMON IN THE SHEARED CONTACT ZONE. THE AREA WAS REPORTEDLY DRILLED AS A MOLYBDENUM TARGET IN THE 1968-1973 PERIOD; POSSIBLY THIS EXPLORATION WAS CENTERED ON THE GRANITE PORPHYRY. |
