Comments on the production information

  • THE AVERAGE COVER THICKNESS FOR MOST OF THE PROPOSED MINES IS REPORTED AS ZERO BECAUSE THE ORE ZONE IS EXPOSED IN EXISTING OPEN PIT MINES. THE S8 MINING RECORD HAS A GREATER CAPACITY THAN THE MILL CAPACITY. FOR THIS TIME PERIOD IT IS ASSUMED THAT THE MILL WILL OPERATE AT GREATER THAN 100 PERCENT CAPACITY. MINE PERMANENTLY CLOSED IN 1986.
