Comments on the reserve resource information

  • MINING CONDITIONS ARE FAVORABLE FOR EXTRACTION OF THE ENTIRE UNIT. ADDITIONAL EXPLORATION IS NECESSARY TO DETERMINNE WHETHER THE MEMBER COULD BE MINED AS A UNIT AND STILL MAINTAIN FURNACE-GRADE. ADITS DRIVEN NEAR THE CREEK LEVEL WOULD PROVIDE BACKS OF ABOUT 700 FT ON THE E LIMB AND 300 FT ON THE W LIMB.

Comments on the workings information

  • 2 ADITS, TRENCHES
