Subject category Comment text
Deposit AT THE NORTHERN WORKINGS, A 40 CM WIDE MASSIVE TO RARELY VUGGY QUARTZ VEIN CUTS FLOW-BANDED (LOCALLY) METARHYOLITE-. THE VEIN CONTAINS LIMONITE GOSSAN BUT ONLY RARE REMNANT PYRI-TE WAS NOTED. THE WALLROCK NEAR THE VEIN IS SOMEWHAT ARGILLIZE-D FOR A SHORT DISTANCE AWAY FROM THE VEIN. NEARBY KOIPATO IS A- LITHIC VITRIC WELDED TUFF. THE QUARTZ VEIN ATTITUDE IS N30E, -65 NW. AT THE SOUTH WORKINGS, MASSIVE TO RARELY VUGGY MILKY QU-ARTZ VEIN MATTER OCCURS IN VEINS IN A MASSIVE MEDIUM GRAY LIME-STONE OF THE PRIDA FM. THE ATTITUDE OF THE VEIN OR VEINS WAS N-OT DETERMINED. VEINS CONTAIN LIMONITE, MALACHITE, RARE AZURITE- AND CHALCOCITE.
