<P>This report consists of the unaudited consolidated Financial Statements issued by Compa&ntilde;&iacute;a de Minas Buenaventura S.A.A. and subsidiaries for the third quarter 2004 and for the nine-month period ended on September 30, 2004and released on October 28, 2004</P>

<P>&nbsp;</P>
</FONT><FONT SIZE=3><P>1. We have made a limited review of the consolidated balance sheet, and the consolidated statements of income, changes in shareholders' equity and cash flows of <B>Compa&ntilde;&iacute;a de Minas Buenaventura S.A.A.</B> (a Peruvian company) <B>and subsidiaries</B> (together, &quot;the Company&quot;) as of September 30, 2003 and 2004, and for the three-month and nine-month periods then ended, stated in Peruvian Nuevos Soles.  These consolidated financial statements are the responsibility of the Company's management.</P>

<P>2. The financial statements of Minera Yanacocha S.R.L. (an affiliated entity in which the Company has a 43.65 percent interest) as of September 30, 2003 and 2004, and for the three-month and nine-month periods then ended, have been reviewed by other independent auditors whose limited review reports dated October 16, 2003 and October 18, 2004, respectively, have been furnished to us.  In the consolidated financial statements of the Company, the investment and share in the net income in this affiliate, as derived from the financial statements of this entity, amounts to S/1,139.9 million as of September 30, 2004 (S/1,194.2 million as of September 30, 2003) and S/392.1 million for the nine-month period then ended (S/375.5 million for the nine-month period ended September 30, 2003), respectively.</P>

<P>3. We conducted our limited review in accordance with applicable auditing standards in Peru for limited reviews.  A limited review of interim financial information consists mainly of applying to the financial data analytical procedures and making inquiries to people responsible for financial and accounting matters.  It is substantially smaller in scope than an audit conducted in accordance with generally accepted auditing standards, the objective of which is to express an opinion on the interim consolidated financial statements taken as a whole.  Accordingly, we do not express such an opinion. </P>

<P>4. Based on our review and on the limited review reports of the auditors of Minera Yanacocha S.R.L., which we have obtained and read, we are not aware of any material modification that should be made to the accompanying interim consolidated financial statements for them to be in conformity with generally accepted accounting principles in Peru.</P>

<P>5. We have previously audited, in accordance with generally accepted auditing standards in Peru, the accompanying consolidated balance sheet of <B>Compa&ntilde;&iacute;a Minera Buenaventura S.A.A. and subsidiaries </B>as of December 31, 2003, and the related consolidated statements of income, changes in shareholders' equity and cash flows for the year then ended (not presented herein).  Our report dated February 27, 2004 expressed an unqualified opinion on those consolidated financial statements.</P>

(&quot;Buenaventura&quot;) and subsidiaries (together, &quot;the Company&quot;), which are maintained in nominal Peruvian currency and adjusted to reflect changes in the National Wholesale Price Level Index (IPM).

<P>&#9;Figures presented in the consolidated financial statements as of December 31, 2003 and for the three-month and nine-month periods ended September 30, 2003 have been inflation adjusted to reflect the change in IPM as of September 30, 2004.</P>

Additionally, in preparing the interim consolidated financial information, Management made certain estimates and assumptions; accordingly actual results may differ from those presented in this report.</P>

<B><P>&#9;Declared and paid dividends from Yanacocha -</P>
</B><P>&#9;Yanacocha paid cash dividends to Condesa for approximately S/73,037,000 and S/257,202,000 for the three-month and nine month periods ended September 30, 2004, respectively (S/169,748,000 and S/266,203,000 for the three-month and nine-month periods ended September 30, 2003).</P>

<P>&#9;<B>Legal proceedings</P>
</B><P>&#9;<B>Mercury spill incident near the town of Choropampa -</P>
</B><P>&#9;In June 2000, a transport contractor of Yanacocha spilled approximately 11 liters of mercury near the town of Choropampa, Peru, which is located 84.8 kilometers away from Yanacocha. As a consequence of this damage, on September 10, 2001, Yanacocha and other defendants were named in a lawsuit by over 900 Peruvian citizens in the Denver District Court of the state of Colorado in the United States (hereafter &quot;the Court&quot;).  This action seeks compensatory and punitive damages based on claims associated with the mercury spill incident. This action was dismissed by the Denver District Court on May 22, 2002 and this ruling was reaffirmed by the Court on June 30, 2002. Plaintiffs' attorneys have appealed this dismissal.</P>

<P>&#9;In July 2002, Yanacocha and certain subsidiaries of Newmont Mining Corporation were served with other lawsuits in the Denver District Court for the State of Colorado and in the United States District Court for the District of Colorado, by approximately 140 additional Peruvian plaintiffs and by the same plaintiffs who filed the September 2001 lawsuit.  These actions also seek compensatory and punitive damages based on claims associated with the mercury spill incident near the town of Choropampa.  These lawsuits have been stayed pending the outcome of the first appeal.  At the date of the report, Yanacocha can not reasonable predict the final outcome of any of the described lawsuits and estimates that an adverse decision is not expected to have a material adverse effect on the Yanacocha's financial condition.</P>

<B><P>&nbsp;</P>
<P>&#9;Cerro Quilish -</P>
</B><P>&#9;Yanacocha was involved in a dispute with the Provincial Municipality of Cajamarca regarding the authority of this entity to regulate the development of the Cerro Quilish ore deposit (which contains reserves of approximately 3.7 million ounces of gold). Cerro Quilish is located in the same watershed in which the City of Cajamarca is located. The Municipality has enacted an ordinance declaring Cerro Quilish and its watershed to be a reserve and naturally protected area.  Yanacocha has challenged this ordinance on the grounds that, under Peruvian law, local governments lack authority to create such areas. In May 2002, the Peruvian Constitutional Court was installed in Lima to hear the case. The case was heard in early 2003 and the Court ruled on April 7, 2003 and established that the Yanacocha right to prospect and explore, according to its mining concessions, are free and clear from encumbrance.</P>

<P>&#9;The Court has required Yanacocha to complete a full environmental impact study, conducted by independent and certified organizations or institutions, prior to initiating any development at Cerro Quilish, and adopt mitigation measures necessary to protect the quality and quantity of the water supply of the city of Cajamarca.</P>

<P>&#9;On July 20, 2004, the Company received the Directorial Resolution 361-2004-MEM/AAM of the Ministry of Energy and Mining, that gave to Yanacocha the &quot;Permission Type C&quot; to begin the exploration activities in this zone.  As a consequence of the claims realized by the citizens of Cajamarca, on September 16, 2004 the Peruvian Government, through the Directorial Resolution 427-2004-MEM/AAM of Ministry of Energy and Mining, derogated the Directorial Resolution 361-2004-MEM/AAM.  At the date of the report, Yanacocha's management despite are supported with all the legal rights to realize the exploration activities in the zone of Cerro Quilish, has done public its decision of not continue temporally with the exploration activities in this zone.</P>

<P>&#9;<B>Arbitration with a contractor -</P>
</B><P>&#9;In June 2004, as a part of the conciliation process with a contractor, the Management of Yanacocha agreed to pay this contractor an indemnity of US$2.5 millions.  Through this payment, Yanacocha finished the arbitration process started in November 2003, relating to a fee and contractual dispute for civil construction works performed at Carachugo mine site. The original amount of the claim was approximately US$12 millions. </P>

<B><P>11.&#9;Legal proceedings</P>
<P>Damages claimed by a French citizen -&#9;</P>
</B><P>In February of 2002, the Company and Condesa, together with Newmont Mining, Newmont Second and certain individual persons, were defendants in an action initiated by a French citizen, with jurisdiction before the District Court of the state of Colorado in the United States.  The plaintiff alleges that he was engaged as an advisor to Normandy respective to a lawsuit that concluded in October of 1998, and that such lawsuit separately motivated the execution of a Global Transaction Agreement in 2000 between the Company, BRGM, Mine Or, Normandy and their related entities (SEREM).  The Global Transaction Agreement provided for full and permanent revocation and annulment of any preferential rights on the shares of Compa&ntilde;&iacute;a de Exploraciones, Desarrollo e Inversiones Mineras S.A.C. - CEDIMIN, in exchange for a one-time payment of US$80 million by the Company, of which the Company paid US$40 million.</P>

<P>The plaintiff asserts that he was injured because Normandy had promised to pay him a commission based fee if he was able to increase the amount of the Company's payment as ordered by the Court, which did not occur, and seeks damages of not less than US$25 million plus interest, in addition to unspecified punitive damages that could increase the amount by threefold. Additionally, the plaintiff alleges violations of the federal RICO statute and similar provisions of Colorado law, interference with contract rights, defamation and other damages.</P>

<P>The defendants have filed various motions to dismiss the action and believe the arguments presented for dismissal have solid legal ground; however, rather than responding to these motions for dismissal, the plaintiff has filed another demand.  The Company and Condesa have presented motions to reject the new demand.  On January 15, 2004, the judge Richard P. Matsch of the state of Colorado of the United States of America dismissed the new demand.  On February 15, 2004, the plaintiff appealed the outcome to the Federal Court of the United States of America - Tenth Circuit (Colorado).</P>
<P>The position of the Company has been presented and is in process of being solved by the Court.</P>

<B><P>Other -</P>
</B><P>From time to time in the normal course of its activities, the Company is involved in various legal proceedings of a diverse nature.  Management believes that any possible loss, which may result from these lawsuits, will not have a materially adverse effect on the Company's financial position.</P>

<B><P>12.&#9;Deferred income tax and workers' profit sharing</P><DIR>

</B><P>(a)&#9;The deferred income tax and workers' profit sharing asset mainly includes an effect of S/241,455,000 from the deferred revenue from sale of future production and of S/16,734,000 from the long-term officers' compensation (S/252,505,000 and S/17,142,000 as of December 31, 2003, respectively).</P>

<P>&#9;<B>Normal sale contracts of gold -</P>
</B><P>&#9;Effective December 30 and 31, 2003, Buenaventura modified the terms of certain derivative instruments contracts in order to qualify them as normal sale contracts.  The fair value of these contracts at the date prior to the modification of terms amounted to S/709,963,000 and was presented as &quot;deferred revenue from sale of future production&quot; in the consolidated balance sheet as of December 31, 2003.  Since this date, the amount will be included in the future results as delivery of the committed ounces of gold occurs.</P>

<P>&#9;During nine-month period ended September 30, 2004, Buenaventura delivered 136,000 ounces of gold as a part of the sale contracts above mentioned.  As a consequence, Buenaventura recognized revenues of S/16,353,000 and S/47,292,000 for the three-month and nine-month periods ended September 30, 2004, respectively, in the caption &quot;realized revenue from sale of future production&quot; in the consolidated statements of income.

This operation has generated a loss for approximately S/484,000 during the nine-month period ended September 30, 2004 (approximately S/1,508,000 during the nine-month period ended September 30, 2003), basically explained for a lower market exchange currency rate compared to the exchange rate at the maturity date during this period.  The fair value of this contract as of September 30, 2004 amounts to S/3,108,000 and is presented in the caption &quot;other current liabilities&quot; of the consolidated balance sheet.</P>

<P>15.&#9;New legal regulations</P>
</B><P>In June 24, 2004, the Peruvian Congress approved Law 28258 - Law of Mining Royalties.  This law seeks to establish the mining royalty that owners of mining concessions should pay for the exploitation of metallic and non-metallic resources.   The mining royalties will be calculated with rates ranging from 1% to 3% over the mineral concentrates value or equivalent, according to the quoted market price published by the Ministry of Energy and Mines.  At the date of this report, changes in this law are under evaluation and the ruling of this law is pending of approval. </P>
