Comments on the geologic information

  • LIMEY SHALE AND LIMESTONE LOCATED 100 FT. ABOVE THE TUNNEL IS ALTERED TO TACTITE & A STOCKWORK OF QUARTZ VEINS CONTINOUSLY OUTCROP WITH A STRIKE OF N70E AND DIP OF 13SE. SOUTHWEST OF THE TUNNEL PYRITE AND CHALCOPYRITE OCCUR IN VEINLETS, PODS, AND REPLACEMENT OF ALGAL SPHEROIDS WITHIN THE REPLACED HORIZON. GOSSAN IS ABUNDANT IN THE DUMP MATERIAL. THE SWARTZ TUNNEL IS AT OR NEAR THE BASAL CONTACT OF THE PIOCHE SHALE WITH THE PROSPECT MOUNTAIN QUARTZITE

General comments

Subject category Comment text
Deposit SOME OF THE VEIN MATERIAL ON THE DUMP FROM ADIT ABOVE TUNNEL LOOKS PEGMATITIC WITH COARSE WHITE MICA AND COARSE TERMINATED QUARTZ CRYSTALS IN VUGS. BELOW THE ADIT DUMP IS PIOCHE SHALE. ADIT ABOVE TUNNEL DISPLAYS REPLACEMENT HORIZON IN ONE OF THE BASAL LIMESTONE UNITS OF PIOCHE SHALE. THE LIMESTONE IS SILICIFIED AND NOW DISPLAYS A TYPICAL TACTITE MINERAL ASSEMBLAGE OF DIOPSIDE, CALCITE, AND EPIDOTE WITH SOME FLUORITE, PYRITE AND CHALCOPYRITE THROUGHOUT. SPHALERITE IS ALSO PRESENT. THE ALTERED HORIZON AT THE MOUTH OF THE ADIT IS REDDISH-BROWN SILICIFIED LIMESTONE WITH POLKA DOT APPEARANCE FROM ALGAL GIRVANELLA. THIS HORIZON IS CAPPED BY GOSSAN WHICH CAN BE FOLLOWED FOR 100 FT OR MORE TO THE SW. AT THE RIDGECREST SW OF SCWARTZ WORKINGS IS AN OLD SHAFT AND SEVERAL DOZER TRENCHES. THE REPLACED HORIZON RECURS HERE. A COARSE, BLADED, GREENISH WHITE MINERAL (WOLLASTONITE? TREMOLITE?) OCCURS ON THE VEIN SELVAGES.
