Comments on the reserve resource information

  • Assay Grade In Reserves Record 2 And Reserves Record 3 Actually Reflects The Acid-Soluble (Recoverable) Copper Content.
  • Oxide Resource Is 50 Million Mt @ 0.27 % Cu (Demo) Or 125 Million Mt (Ident). Copper Evaluation Has Priority At His Property (In Which Silver Is Byproduct). Ditto Mineral Park, Mission-San Xavier, Oracle Ridge, Pima, And Silver Bell (Float). Per Mj 9/18/87 Bagdad Is Producing Over 5mlb Of Byproduct Mo/Yr. Bagdad Mined 26 Million Mt Ore In 1992 And Produced 99,610 Mt Copper Of Which 8.8% Was Produced From Dump Leach/Sx-Ew Operation. 1994 Data From Mining Business Digest, May 1994, P. 5. The Silver Adit Grade Was Not Updated In 1996.
  • Ag Grade In Matrix 1, Column 1, Is An Estimate Derived From Company Supplied Data. M1c1=R5 Matrix 1 Column 1 Equals Reserve Column 5. Matrix 2 Represents The Dump Leach Reserve. The Grade Is The Acid Soluable Copper Content. . M9c5=M2c1 Matrix 9 Column 5 Equals Matrix 2 Column 1.
