Comments on the geologic information

  • THE DEPOSIT CONSISTS OF SMALL LENSES OF HIGH-GRADE FLUORSPAR IN LIMESTONE & ARGILLITE. MAIN FLUORSPAR VEIN OCCURS ALONG A NW-TRENDING FAULT ZONE. MOST OF VEIN CONTAINS NO FLUORITE, BUT FLUORITE-RICH PORTIONS OCCUR IN SEVERAL PLACES. MAIN FLUORSPAR BODY HAS PODLIKE SHAPE ABOUT 10 FT. LONG AND 5-2 FT. WIDE. IRREGULAR & MOSTLY RANDOM FLUORSPAR VEINLETS ARE ABUNDANT FOR ABOUT 3 FT. IN HANGING WALL.
