Compañia de Minas Buenaventura Announces Third Quarter 2010 Results Lima, Peru, October 28, 2010 – Compañia de Minas Buenaventura S.A.A. (“Buenaventura” or “the Company”) (NYSE: BVN; Lima Stock Exchange: BUE.LM), Peru’s largest, publicly-traded precious metals mining company announced today its results for the third quarter 2010. All figures have been prepared according to Peruvian GAAP and are stated in U.S. dollars (US$). Comments from the Chief Executive Officer: Mr. Roque Benavides, Buenaventura’s Chief Executive Officer stated: “Net income during the quarter was US$174.1 million, a 17% increase when compared to the figure reported in 3Q09 (US$148.5 million), mainly due to a 54% increase in operating income. EBITDA from Buenaventura’s Direct Operations was US$116.9 million, 15% higher than the figure reported in 3Q09 (US$101.9 million), while EBITDA including Yanacocha and Cerro Verde increased 3%, from US$313.5 million in 3Q09 to US$323.9 million in 3Q10. These results were mainly driven by higher metal prices, an increase in silver, lead and gold sold, as well as the solid results from Cerro Verde”.

Operating Revenue

During 3Q10, net sales were US$265.9 million, a 24% increase when compared to the US$214.6 million reported in 3Q09. This was explained by the higher realized prices in all metals and an increase in the volume of gold, silver and lead sold.

Royalty income in 3Q10 totaled US$14.0 million, a 14% decrease when compared to the US$16.2 million reported in 3Q09 due to lower gold volume sold at Yanacocha.

Cash operating cost in 3Q10 was US$12.82/oz, a 21% increase compared to the $10.62/oz in 3Q09. This was best explained by:

23% higher labor costs mainly explained by a non-recurring negotiation closure bonuses (70% of the total increase), as well as an increase in salaries and the 5% appreciation of the Nuevo Sol.

A 33% rise in contractor expenses due to higher productivity bonuses.

Total royalties paid to the government at Uchucchacua in 3Q10 totaled US$1.1 million.

At Antapite (100%), total production in 3Q10 was 9,396 ounces of gold, an increase of 13% compared to 3Q09 (8,297 ounces), mainly due to a 16% increase in ore treated (Appendix 2). Accumulated gold production was 26,026 ounces, an 11% increase when compared to 2009 (23,430 oz).

Operating Expenses

General and administrative expenses in 3Q10 were US$27.9 million, 18% lower than the figure reported in 3Q09 (US$34.2 million) due to a lower ‘mark to market’ provision for long-term compensation (US$15.9 million in 3Q10 vs. US$20.8 million in 3Q09). General and administrative expenses in the nine-month period 2010 totaled US$66.8 million, a 4% lower than the US$69.9 million reported in the same period of 2009.

Exploration Costs in Non-Operational Mining Sites

Exploration costs at non-operational mining sites, which include care and maintenance, in 3Q10 were US$7.8 million, a 10% increase compared to the US$7.1 million reported in 3Q09. The main efforts were focused at the Castrejon prospect at La Zanja (US$0.9 million), Mallay (US$0.9 million), El Brocal (US$3.2 million) and Colquemayo (US$0.5 million) projects.

Exploration costs at non-operating mining sites in the nine-month period 2010 were US$25.9 million, a 7% increase when compared to the same period in 2009 (US$24.3 million).

Operating Income

Operating income in 3Q10 was US$96.5 million, a 54% increase compared to the US$62.8 million reported in 3Q09. This result was mainly explained by higher revenues and lower administrative expenses.

Accumulated operating income for the period was US$218.8 million, an increase of 13% when compared to the figure reported in 2009 (US$193.3 million).

Share in Affiliated Companies

During 3Q10, Buenaventura’s income from non-consolidated affiliates was US$118.1 million, 6% lower than the US$125.5 million reported in 3Q09. Yanacocha’s contribution to these results decreased 29%, from US$88.2 million in 3Q09 to US$62.4 million 3Q10, partially offset by a 56% increase in contributions from Cerro Verde, which rose from US$37.3 million in 3Q09 to US$58.1 million in 3Q10.

Accumulated income from non-consolidated affiliates in the nine-month 2010 period was US$316.2 million, an increase of 4% compared to the US$303.8 million reported in 2009.

YANACOCHA

At Yanacocha (43.65%), 3Q10 gold production was 355,150 ounces of gold, a decrease of 35% compared to 3Q09 (543,854 ounces). Gold production in the nine-month 2010 period was, according to guidance, 1,130,504 ounces, but a decrease of 28% compared to the 1,559,465 ounces reported in the same period 2009.

Cost applicable to sales (CAS) at Yanacocha in 3Q10 was US$437/oz, 42% higher than the figure reported in 3Q09 (US$308/oz) due to higher diesel costs, higher labor costs (including worker’s participation) and an increase in royalties.

Compañia de Minas Buenaventura S.A.A.

Third Quarter and Nine-Month 2010 Results

Page 6 of 13

Net income at Yanacocha in 3Q10 was US$143.6 million, a 29% decrease when compared to the 3Q09 figure (US$202.8 million). Accumulated net income in 2010 was US$450.5 million, a 10% decrease from 2009 (US$498.5 million).

During 3Q10, EBITDA totaled US$253.9 million, a decrease of 24% compared to 3Q09 (US$336.3 million). This decrease was explained by the 19% decline in revenues (US$436.4 million in 3Q10 vs. US$535.8 million in 3Q09) due to a 36% decrease in ounces of gold sold. EBITDA for 9M10 was US$781.4 million, a 9% decrease when compared to the US$858.5 million reported in 2009.

The Company continues to expect total 2010 gold production at Yanacocha to be between 1,460,000 and 1,550,000 ounces, with costs applicable to sales near the high end of $360 and $400 per ounce. This is due primarily to higher royalties and worker’s participation costs as a result of higher realized gold prices.

CAPEX in 3Q10 was US$84.3 million, while for the cumulative period, CAPEX totaled US$194.9.

CERRO VERDE

At Cerro Verde (19.26%), 3Q10 copper production was 74,768 MT, a 2% increase when compared to 3Q09 (72,973 MT). Accumulated copper production in 9M10 totaled 225,108 MT, in-line with the same period 2009 (225,498 MT).

During 3Q10, Cerro Verde reported net income of US$304.1 million, a 53% increase when compared to US$198.1 million in 3Q09. Accumulated net income in 9M10 was US$679.5 million, a 46% increase compared to the same period 2009 (US$463.9 million).

CAPEX in 3Q10 totaled US$29.2 million, and US$74.8 million for the nine-month period 2010.

Net Income

This quarter, Buenaventura’s net income was US$174.1 million, representing US$0.68 per share compared to US$148.5 million in 3Q09 (17% increase). This was mainly explained by the 54% increase in operating income despite a 29% decrease in contributions from Yanacocha.

Net income for the nine-month period 2010 was US$440.2 million (US$1.73 per share), a 15% increase when compared to the US$383.2 million (US$1.51 per share) reported in the same period 2009.
