Copper Corporation to Issue Notes for US$400 million</font></u></b></p>

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Phoenix, Arizona, May&nbsp;4,
2006 &#151; Southern Copper Corporation (&#147;SCC&#148;) (NYSE and LSE: PCU), a subsidiary of
Grupo Mexico, announced today it has priced an additional offering pursuant to Rule&nbsp;144A
and Regulation S under the Securities Act of 1933, of US$400 million 7.500%
coupon Notes due 2035. The transaction is expected to close on May&nbsp;9,
2006.</font></p>

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Notes will be in
addition to the US$600 million of existing 7.500% Notes due 2035 that SCC
issued in July&nbsp;2005. Net proceeds from the issuance of the Notes will be
used to partially fund the US$600 million expansion program of SCC&#146;s operations
in Mexico and Peru.</font></p>

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The current transaction
was issued at a spread of +240 basis points over the 30-year U.S.
Treasury bond. The original issue in July&nbsp;2005 was issued at a spread of
+315 basis points over the 30-year U.S. Treasury bond. The demand for the
Notes was over two times the size of the issue and came from over 70
institutional investors in the U.S., Europe, and Asia. The Notes are Investment
Grade rated Baa2 by Moody&#146;s, BBB- by Standard&nbsp;&amp; Poors, and BBB- by
Fitch.</font></p>
