Comments on the reserve resource information

  • ABOUT 10 METRIC TONNES OF MN OXIDE BOULDERS ARE PILED IN THE STREAM BELOW OUTCROP, BUT THE ORE IS TOO LOW GRADE AND TOO SILICEOUS TO SHIP. NOT PROMISING COMMERCIALLY. THE ORE IS TOO LOW GRADE, TOO SILICEOUS, AND TOO SMALL IN QUANTITY AT THE OTHER FOUR CLAIMS TO WARRANT MORE EXPLORATION.

  • SHALLOW CUTS.

Comments on development
