        [LOGOS OF CYPRUS AMAX MINERALS COMPANY AND ASARCO INCORPORATED]


ATTENTION ASARCO AND CYPRUS AMAX SHAREHOLDERS:

                            THE ASARCO CYPRUS MERGER:
                    THE ONLY TRANSACTION THAT GIVES YOU VALUE
                      THE ONLY TRANSACTION YOU CAN COUNT ON

By VOTING FOR the Asarco Cyprus merger, shareholders will:

     o    CREATE the largest publicly-traded copper company in the world.

     o    RECEIVE a cash payment of $5.00 per Asarco Cyprus share after closing.

     o    RETAIN 100 percent of the $275 million of annual savings created by
          the merger.

     o    REALIZE the values of Asarco Cyprus' global presence and world-class
          properties, enhanced financial strength, and increased shareholder
          liquidity.

Cyprus Amax and Asarco shares outperformed Phelps Dodge's shares following the
announcement of the Asarco Cyprus merger and before Phelps Dodge's unsolicited
hostile takeover attempt:

          period between July 14 and August 19. Base value assumption:

Phelps Dodge WANTS TO BREAKUP the Asarco Cyprus merger and DENY YOU the values
to which you are entitled. Phelps Dodge:

     o    IS OFFERING you a discount to the value created by a merged Asarco
          Cyprus.

     o    DOES NOT want to give you fair and appropriate ownership in a
          three-way enterprise even though Cyprus Amax and Asarco would be
          contributing 57 percent of the production, 61 percent of the copper
          reserves and 92 percent of the cost savings.

     o    CAN NOT complete its exchange offer by September 30, if ever.

You have every right to question whose interests Phelps Dodge is promoting. On
September 8, 1999, the Cyprus Amax and Asarco Boards unanimously rejected Phelps
Dodge's exchange offer as inadequate and not in the best interests of Cyprus
Amax and Asarco shareholders.

THE BOARDS OF CYPRUS AMAX AND ASARCO UNANIMOUSLY RECOMMEND THAT SHAREHOLDERS
VOTE FOR THE ASARCO CYPRUS MERGER ON SEPTEMBER 30, 1999.




             It is the only transaction that assures you of value.
                    It is the only transaction you can count on.
