Report of Independent Auditors

To the Shareholders of Compañía de Minas Buenaventura S.A.A.

1. We have reviewed the accompanying consolidated balance sheet of Compañía de Minas Buenaventura S.A.A. (a Peruvian company) and subsidiaries as of June 30, 2008, the related consolidated statements of income and cash flows for the three-month and six-month periods ended June 30, 2008 and 2007 as well as the consolidated statements of changes in shareholders’ equity for the six-month periods then ended. The preparation of these consolidated financial statementsare the responsibility of the Company’s management. Our responsibility is to issue a report on these consolidated financial statements based on our review.

2. The financial statements of Minera Yanacocha S.R.L. as of June 30, 2008 and 2007 and for the three-month and six-month periods then ended have been reviewed by other auditors, whose reports have been furnished to us. In the consolidated financial statements of the Company, the Company’s investment in Minera Yanacocha S.R.L. amounts to US$658.84 million as of June 30, 2008 (US$577.5 million as of December 31, 2007); in addition the share in the net income of this entity amounts to US$125.0 million for the six-month period then ended (US$34.4 million for the six-month period ended June 30, 2007).

3. We conducted our review in accordance with applicable auditing standards in Peru for interim reviews. Those standards require 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 such an opinion on the accompanying consolidated financial statements.

4. Based on our review and on the limited reports of the independent auditors of Minera Yanacocha S.R.L. we are not aware of any material modification that should be made to the accompanying consolidated financial statements referred above to be in conformity with generally accepted accounting principles in Peru.

We have previously audited, in accordance with generally accepted auditing standards in Peru, the accompanying consolidated balance sheet of Compañía de Minas Buenaventura S.A.A. and subsidiaries as of December 31, 2007, and the related consolidated statements of income, changes in shareholders’ equity and cash flows for the year then ended.

2. Interim unaudited consolidated financial statements

Basis of presentation -

The interim unaudited consolidated financial statements for the three and six-month periods ended June 30, 2008 had been prepared in conformity with IAS 34 “Interim Financial Reporting”.

The interim consolidated financial statements do not include all the information and disclosures required in the Company’s annual consolidated financial statements and should be read together with the consolidated financial statements as of December 31, 2007.

Significant accounting principles and practices -

(a) The criteria and accounting basis used by the Company in preparing the accompanying interim consolidated financial statements are consistent to those used in the preparation of the Company’s annual consolidated financial statements.

(b) Net income per basic and diluted shares is calculated on the basis of the weighted average number of the common and investment shares outstanding as of the date of the consolidated balance sheets, without considering treasury stock. When the number of shares is modified as a result of capitalization of retained earnings, share splits or share grouping, the net income per basic and diluted shares is adjusted retroactively for all of the periods reported. If the change occurs after the date of the consolidated financial statements, but before the financial statement are authorized to issue, the calculation of net income per basic and diluted shares for all of the reported periods must be based on the new number of shares.

Reclassifications -

The Company did not make significant reclassifications to its interim consolidated financial statements for the three and six-month periods ended June 30, 2008 and 2007.

3. Seasonality of operations

The Company and its subsidiaries operate continuously without fluctuations due to seasonality.

10. Net sales

The sales in the first semester of 2008 (US$416,271,000) increased by 26 percent compared to the first semester of 2007 (US$332,259,000). During the first semester of 2008, the Company sold 172,936 gold ounces at an average market quotation of US$909.94, compared with 40,000 gold ounces at an average fixed price of US$340.00 and 159,906 gold ounces at an average market quotation of US$653.01 in the same period of 2007. The higher sales prices obtained during the first semester of 2008, results from the modification of schedule of commitments of gold ounces and for the release of fixed-price component in sales contracts which were made in January 2007 and in the months of January and February of 2008, respectively.

The increase in the sales for the higher prices of gold was partially off set by the decrease of the gold ounces sold. See note 14(a).

During the six month period ended June 30, 2008 El Brocal’s sales decreased approximately in US$7,849,000 in respect the same period of 2007 which is mainly explained by the net effect between increase in the sales for US$22,318,000 as a result of to start up phase of copper concentrate plant at the end of the year 2007, which allow to sale 19,466 MT of copper concentrate, the decrease of the zinc sales by US$19,741,000 as a consequence of the minor zinc quotation which was compensated with higher volumen sold of zinc and the decrease of lead sales.

Normal sales contracts -

In March and May of 2007, Buenaventura reviewed the sales contracts with six of its customers, to release the fixed-price or higher price to sell certain number of committed ounces and to sell those gold ounces between the years 2008 - 2012 at market prices.

As a consequence, Buenaventura was released from the obligation to sell 971,000 ounces of gold at fixed prices; consequently, they will be sold according at the market price prevailing at the date of the physical delivery of the gold committed.
