<P>This report, dated November 4, 2004, by Compa&ntilde;&iacute;a de Minas Buenaventura S.A.A. (the &quot;Company&quot;) discloses Minera Yanacocha S.R.L. (&quot;Yanacocha&quot;) request for the revocation of its Cerro Quilish drilling permit to enable it to further explore and define the Cerro Quilish deposit.</P>

</B><P ALIGN="JUSTIFY">&nbsp;</P>
<P ALIGN="JUSTIFY">In October 2000, the Provincial Municipality of Cajamarca enacted an ordinance declaring Cerro Quilish and its watershed to be a reserved and natural protected area. Cerro Quilish is an ore deposit that contains reserves of 1.6 million equity ounces and is located in the same watershed as the City of Cajamarca. Minera Yanacocha S.R.L. (&quot;Yanacocha&quot;).  challenged this ordinance on the grounds that, under Peruvian law, local governments lack authority to create such areas. The case was heard in early 2003, and on April 30, 2003, the Constitutional Tribunal issued a decision holding that, because Yanacocha acquired the mining concessions in the Cerro Quilish area many years before the adoption of the contested ordinance, its rights were not impacted by the ordinance. On May 8, 2003, the Constitutional Tribunal reaffirmed its ruling in this mater.</P>
<P ALIGN="JUSTIFY"></P>
<P ALIGN="JUSTIFY">Yanacocha is committed to completing a full environmental impact study prior to initiating any development at Cerro Quilish, and will adopt mitigation measures necessary to protect the quality and quantity of the water supply of the City of Cajamarca. While the central government has the primary responsibility and the necessary technical expertise to regulate this matter, the Company is also committed to working with the local government and other affected stakeholders in completing the required studies and designing and implementing any necessary mitigation measures.</P>
<P ALIGN="JUSTIFY"></P>
<P>In the third quarter 2004, Yanacocha received a drilling permit for the Cerro Quilish deposit and commenced drilling activities to further define the deposit.  During September 2004, individuals from the Cajamarca region conducted a sustained blockade of the road between the City of Cajamarca and the mine site, in protest of these exploration activities.  Yanacocha suspended all drilling activities at Cerro Quilish and the blockade was resolved.  Yanacocha has now requested the revocation of its Cerro Quilish drilling permit, and the Company will reevaluate, as part of its year end reserve estimation process, whether the deposit's 1.6 million equity gold ounces should remain in reserves.</P>
