Comments on the geologic information

  • A FEW TONS OF ORE LIE ON THE DUMP. PYRRHOTITE PREDOMINATES, WITH SOME PYRITE CUBES, A LITTLE CHALCOPYRITE, AND SCARCE SPHALERITE. ON THE NORTHWEST SIDE OF THE RIDGE, A 20-FOOT DEEP BY 20-FOOT WIDE OPEN CUT EXPOSES QUARTZ-BIOTITE GNEISS AND QUARTZ VEINS, BUT SULFIDES WERE NOT OBSERVED. A 10-FOOT DEEP PIT IS ABOUT 600 FEET DOWN THE GULLEY, AND CONSIDERABLE PYRITE AND VEIN QUARTZ ARE PRESENT, ASSOCIATED WITH A 3-FOOT WIDE GOSSAN. THE GOSSAN RANGES FROM 3 TO 10 FEET IN WIDTH, AND WAS TRACED ON THE SURFACE FOR APPROXIMATELY 1,147 FEET. THE SPONGY RED AND BROWNISH LIMONITE LOCALLY CONTAINS SMALL QUARTZ GRAINS AND IN THE INCLINE, POCKETS OF "BLACK COPPER". HENDRY'S REPORT (1932) STATES THAT "IN THE ORE PATCHES OF AUGITE-GARNET GRANITE CARRYING SMALL AMOUNTS OF ORE MATERIAL WERE OBSERVED. THE ORE MINERALS ARE CHALCOPYRITE, PYRITE, BORNITE, AND PYRRHOTITE INTERGROWN WITH GANGUE OF QUARTZ, GARNET, AND AUGITE. THE AVERAGE PERCENT OF COPPER IS REPORTED TO BE FROM 2 TO 4 PERCENT."

Comments on the workings information

  • TWO PITS AND A TUNNEL HAVE BEEN DUG. THE TUNNEL TRENDS N 80 W FOR 115 FT TO THE GOSSAN, THEN ALONG THE GOSSAN FOR 20 FT, AND THEN A WINZE FOLLOWS THE ORE BODY DOWNWARD FOR ABOUT 30 FT IN A N 35 E DIRECTION. THE THICKNESS OF THE GOSSAN IS AT LEAST 6 FT; ONLY THE FOOTWALL IS EXPOSED IN THE WINZE.
