Comments on the geologic information

  • SHEAR ZONE NO. 1 LESS THAN 500 FT LONG, ONE FOOT WIDE; VEIN WELL EXPOSED BY WORKINGS. SHEAR ZONE NO. 2 ABOUT 30 FT LONG AND 2.5 FT WIDE. SHEAR ZONE NO. 3 ABOUT 260 FT LONG, UP TO TWO FEET WIDE; CONTAINS RED, MASSIVE BARITE WITH WHITE CLEAVAGE MASSES. SHEAR ZONE NO. 4 ABOUT 50 FT LONG, .5 FT WIDE. THESE ZONES ONLY WEAKLY RADIOACTIVE. SHEAR ZONE NO. 5 MOST RADIOACTIVE ON PROPERTY; MOST MINERALIZATION AND RADIOACTIVITY CONCENTRATED IN SOUTHEASTERN 100 FT; OVERALL IT IS 2700 FT LONG, TO 4 FT WIDE; AT NORTHWEST END MINERALIZATION OCCURS WHERE SHEAR ZONE CUTS A SYENITE DIKE. SHEAR ZONE NO. 6 ABOUT 200 FT LONG AND 2 FT WIDE. SHEAR ZONE NO. 7 CONTAINS MALACHITE, COPPER SULFIDES IN QUARTZ-BARITE VEIN, WITH NO RADIOACTIVITY. MOST OF SHEAR ZONES HAVE STRONG FETID ODOR; SHEAR ZONES GENERALLY NUMBER FROM SOUTHWEST TO NORTHEAST EXCEPT THAT SHEAR ZONES 6 AND 7 LIE BETWEEN SHEAR ZONES 1 AND 5 TO THE SOUTHEAST
