</FONT><P>To the Shareholders of <B>Compa&ntilde;&iacute;a de Minas Buenaventura S.A.A</B>.</P>
<P>1. We have reviewed the accompanying consolidated balance sheet of <B>Compa&ntilde;&iacute;a de Minas Buenaventura S.A.A. </B>(a Peruvian company)<B> and subsidiaries </B>as of September 30, 2005 and the consolidated statements of income, changes in shareholders' equity and cash flows for the three-month and nine-month periods ended September 30, 2005 and 2004. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to issue a report on these consolidated financial statements based on our review.</P>
<P>2. The financial statements of Minera Yanacocha S.R.L. (an equity accounted affiliated entity in which the Company has an 43.65 percent interest) as of September 30, 2004 and 2005, and for the three-month and nine-month periods then ended, have been reviewed by other auditors whose review report dated October 18, 2004 and October 19, 2005, respectively, has been furnished to us. In the consolidated financial statements of the Company and its subsidiaries, as derived from the financial statements of Minera Yanacocha S.R.L., the Company's investment and share of the net income in this entity amount to approximately S/1,511.7 million as of September 30, 2005 (S/1,139.9 million as of September 30, 2004) and to S/457.6 million for the nine-month period then ended (S/392.1 million for the nine-month period ended September 30, 2004). </P>
<P>3. We conducted our review in accordance with International Standard on Review Engagement 2400. This standard requires that we plan and perform the review to obtain moderate assurance as to whether the financial statements are free of material misstatement. A review is limited primarily to inquire of company personnel and analytical procedures applied to consolidated financial data and thus provide less assurance than an audit. We have not performed an audit and, accordingly, we do not express an opinion.</P>
<P>4. Based on our review, nothing has come to our attention that causes us to believe that the accompanying consolidated financial statements are not presented fairly, in all material respects, in accordance with generally accepted accounting principles in Peru.</P>
<P>5. Effective January 1, 2005 with the purpose of adopting international industry practices, the Company modified its accounting policy for recording the stripping costs, see Note 7. In addition, it suspended the restatement of the financial statements to recognize the inflation effect, see Note 1(a).</P>
<P>&nbsp;</P>
<P>6. We have previously audited, in accordance with generally accepted auditing standards in Peru, the accompanying consolidated balance sheet of <B>Compa&ntilde;&iacute;a de Minas Buenaventura S.A.A. and subsidiaries </B>as of December 31, 2004, and the related consolidated statements of income, changes in shareholders' equity and cash flows for the year then ended. Our report dated February 18, 2005 expressed an unqualified opinion on those consolidated financial statements. </P>

<B><P>1.&#9;Interim unaudited consolidated financial statements</P><DIR>

</B><P>(a)&#9;The accompanying interim consolidated financial statements have been prepared from the accounting records of Compa&ntilde;&iacute;a de Minas Buenaventura S.A.A. ("Buenaventura") and subsidiaries (together, "the Company"). Until December 31, 2004, these financial statements were maintained in nominal Peruvian currency and adjusted to reflect changes In the National Wholesale Price Level Index (IPM). According to such index, prices increased 4.9 percent during the nine-month period ended September 30, 2004.</P>
<P>Effective year 2005, through Resolution No.031-2004-EF/93.01 enacted on May 18, 2004, the Peruvian Accounting Standards Board suspended the restatement of the financial statements to recognize the inflation effect. The restated balances as of December 31, 2004 have been considered as initial balances as of January 1, 2005. </P>
<P>For comparative purposes, figures presented in the consolidated financial statements for the three-month and nine-month periods ended September 30, 2004 have been inflation adjusted to reflect the change in the National Wholesale Price Index (IPM) as of December 31, 2004. </P>
<P>(b)&#9;The criteria and accounting basis by Management in the accompanying interim consolidated financial statements preparation, which should be read together with the 2004 consolidated audited report, are similar to those used in the preparation of the Company's annual consolidated financial statements. 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>

For presentation purposes, the inter-company gains, not recognized by the Company, are presented net of the investment in Yanacocha. </P>
<P>&nbsp;</P></DIR>

<P>&#9;The net increase in the participation in Yanacocha's net income during the nine-month period ended as of September, 2005 compared to the same period as of 2004 is mainly due to increased sales of Yanacocha (price and volume), offset by a slight increase in the cash cost per ounce of gold sold. In addition, this participation is reduced as a consequence of the exchange rate used to convert into Nuevos Soles the participation in Yanacocha's results, reported in U.S. Dollars (S/3.264 and S/3.450 per US$1 for the nine-month periods ended September 30, 2005 and 2004, respectively.

<P>7.&#9;Deferred Striping Costs</P>
</B><P>Until December 31, 2004, with the intent to reasonably match revenues and current production costs, El Brocal was deferring certain costs incurred in the expansion of the Tajo Norte mining site. These costs are commonly referred as "deferred stripping costs" and are incurred in mining activities that are associated with the removal of waste rock to access the ore body. Costs related to additional quantities of waste that must be moved to obtain 1 MT of mineral were deferred when the actual waste material extracted was higher than the estimate; likewise, these costs were amortized when actual waste mineral extraction was lower than the estimate. </P>
<P>Effective January 1, 2005, the subsidiary El Brocal considers the deferred stripping costs incurred during the production stage as variable production costs that should be included in the cost of the inventories produced. This accounting change allows that El Brocal adjusts to industry international practices.</P>
<P>The cumulative effect of this accounting basis, net of workers' profit sharing, income tax and minority interest, was a loss of S/10,416,000 which is separately presented in the consolidated statements of income. This accounting change had no effect on the consolidated financial statements for the three-month and nine-month periods ended September 30, 2004 due to the fact that the stripping costs incurred in such periods were treated as in the current period. </P>

<P>&#9;Legal processes of Buenaventura</P>
</B><P>&#9;As indicated in the note 37(c) of the consolidated audit report as of December 31, 2004, Buenaventura and Condesa, together with Newmont Mining, Newmont Second and certain individual persons, were seeded in a legal action in the Federal Court of the United Stated of America - Tenth Circuit (Colorado) with a French citizen that informed that he was affected by the revocation of BRGM, Mine Or and their related entities (SCRCM) over preferential rights on the shares of Compa&ntilde;&iacute;a de Exploraciones, Desarrollo e Inversiones Mineras S.A.C. - CEDIMIN.</P>
<P>On March 16, 2005 all the involved parts reached to an extrajudicial agreement. As a consequence of this agreement, the demand, pending of motion at the Federal Court of the United States of America - Tenth Circuit and subsequently dismissed by the District Court, was filed definitively. </P>
<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>Legal processes of Yanacocha</P>
</B><P>Mercury spill in Choropampa -</P>
<P>In June, 2000 a Yanacocha's contractor spilled approximately 11 liters of mercury nearby Choropampa, located at 84.8 kilometers from Yanacocha. As a result of the accident, September 10, 2001, 900 Peruvian citizens sue Yanacocha and other persons involved at the District Court of the state of Colorado, United States of America (hereinafter "the Court"). The plaintiffs demand compensations by the damages originated by this spill. In May 22, 2002 the Court misestimated the demand, which was ratified later in June 30, 2002. The plaintiffs appealed this resolution.</P>
<P>&nbsp;</P>
<P>In July 2002, a new demand was presented against Yanacocha and other subsidiaries of Newmont Mining Corporation at the same Court, demanding similar compensations to those of the first demand presented on September 2001. This new demand is in suspense until the appeal of the first one is defined. To this date, Yanacocha considers that it is not possible to predict the final result of these demands and believes that any effect related to them would not be significant to its financial statements.</P>
<B><P>12.&#9;Deferred income tax and workers' profit sharing, net</P>
</B><P>The deferred income tax and workers' profit sharing asset mainly includes an effect of S/256,662,000 from the deferred revenue from sale of future production and of S/16,669,000 from the officers' compensation offset allowance (S/217,696,000 and S/11,922,000 as of December 31, 2004 respectively).</P>

<UL>
<LI>During the three-month and nine-month periods ended September 30, 2005, Buenaventura recognized losses of S/39,814,000 and S/28,373,000 (loss of S/55,133,000 and a gain of S/35,323,000 for three-month and nine-month periods ended September 30, 2004) due to the changes in fair value occurred during those periods. In addition, recognized expenses of S/36,874,000 for the reduction of the Company's hedge book exposure in 120,000 ounces of gold during the first quarter of 2004. These amounts are presented separately in the consolidated statements of income. </LI>
<LI>During the nine-month period ended September 30, 2004, El Brocal credited S/2,584,000, net of minority interest, to the equity account "cumulative unrealized loss on derivative instruments", due to the changes in fair value occurred during that period.</LI></UL>

<DIR>
<DIR>

<P>In addition, the liability presented in the consolidated balance sheets for S/47,028,000 and S/125,832,000 as current and non-current portions, respectively, corresponds to the fair value of derivative instruments of Buenaventura as of September 30, 2005 (S/70,927,000 and S/267,852,000 as current and non-current portions, respectively, as of December 31, 2004). </P>
<P>(b)&#9;Normal sale contracts of gold, zinc and silver</P>
<P>During 2005 and 2003, Buenaventura modified the terms of certain derivative instruments contracts in order to qualify them as normal sale contracts. Likewise, during 2004, El Brocal made similar changes to their derivative contracts in order to qualify them as normal sale contracts. As of September 30, 2005, the settled values for these contracts amounting to S/107,779,000 and S/640,561,000, current and non-current liability, respectively are presented as "deferred income from sale of future production" in the consolidated balance sheets (S/74,937,000 and S/568,772,000 like current and non-current liability as of December 2004). Since this date, such amount will be credited to income as delivery of the committed ounces of gold occurs. </P>
<P>During the three-month and nine-month periods ended September 30, 2005 Buenaventura delivered 72,000 and 196,000 ounces of gold respectively (47,000 and 136,000 ounces of gold for the three-month and nine-month period ended September 30, 2004) as part of the sale contracts above mentioned. As a consequence, Buenaventura recognized revenues of S/23,602,000 and S/65,283,000, for the three-month and nine-month periods ended September 30, 2005 (S/16,353,000 and S/47,292,000 for the three-month and nine-month periods ended September 30, 2004) in the caption "realized revenue from sale of future production" of the consolidated statements of income. </P>
<P>As of September 30, 2005 Buenaventura is committed to sell 2,067,000 ounces of gold at prices ranging from US$332 and US$451 per ounce until December 2012.</P></DIR>
