General comments

Subject category Comment text
Deposit COPPER, IRON AND MN OXIDE MINERALS OCCUR IN MILKY QUARTZ VEIN MATERIAL ALONG A N20E, 70 SE FAULT? A SMALL OUTCROP OF SOMEWHAT ALTERED GRANODIORITE PORPHYRY OCCURS IN ONE TRENCH, BUT THE MAIN WALLROCK IS GREY PHYLLITE WITHIN QUARTZITE. A 50 CM WIDE HIGHLY HEMATITIC ZONE IN THE PHYLLITE OCCURS ALONG STRIKE AWAY FROM THE PIT WITH THE VEIN QUARTZ. REMNANTS OF CHALCOPYRITE AND PYRITE PRESENT IN THE QUARTZ; MALACHITE, WAD, LIMONITE, DARK OXIDE CU MINERALS (?), AND A YELLOW-GREEN, UNIDENTIFIED OXIDE (ARSENATE?) MINERAL OCCUR IN THE VEIN QUARTZ MATERIAL. THE TOTAL WIDTH OF THE VEIN COULD NOT BE DETERMINED, BUT IT DOES NOT EXTEND MORE THAN A FEW METERS HORIZONTALLY, AND IS PROBABLY SPOTTY IN THE MAIN AREA OF EXPOSURE.
