Comments on the geologic information

  • GEOL.DESC: MANGANIFEROUS CHERT; SOME POCKETS OF LOW-GRADE SILICEOUS BLACK OXIDE. THE ORE WOULD PROBABLY NOT RUN OVER 5-10% MANGANESE. THE POCKETS OF SILICEOUS BLACK OXIDE (PYROLUSITE AND PSILOMELANE) MIGHT RUN 35% MANGANESE. OVERLAIN BY SANDSTONE,UNDERLAIN BY WELL BEDDED GREEN CHERT.
