COMPANIA DE MINAS BUENAVENTURA S.A.A

ANNOUNCES THIRD QUARTER 2002 RESULTS

(Lima, Peru October 22, 2002) - Compania de Minas Buenaventura S.A.A. "Buenaventura" (NYSE: BVN / Lima Stock Exchange: BUE.LM), Peru's largest publicly traded precious metals mining company, today announced a net income of S/. 123.0 million or US$33.8 million for the three-month period ended September 30, 2002. This represents an increase of 81% over the net income of S/. 68.0 million in the corresponding quarter of 2001. The Company's operating profit was S/. 50.0 million or US$13.7 million during 3Q2002, representing an increase of 155%, compared to an operating profit of S/. 19.6 million in the corresponding quarter of 2001.

Buenaventura's EBITDA in 3Q02 was US$66.6 million, which represents a 66% increase when compared to the EBITDA of US$40.1 million in the same quarter of 2001.

Sales

During 3Q2002, Buenaventura reported total sales of S/. 159.9 million, compared to S/. 134.3 million during the same period in 2001. The Company attributes the 19% increase to a higher price of goods sold. In this respect, the price of gold applicable to sales in 3Q02 was US$334.30/oz, while in 3Q01 it was US$303.91. Likewise, the price of silver in 3Q02 was US$5.33/oz, while in 3Q01 it was US$ 4.78/oz.

Sales content for the three-month period ended September 30,

	2002	2001
Gold	69,363oz	64,973oz
Silver	2,791,858oz	3,670,815oz
Lead	5,001MT	6,710 MT
Zinc	14,802MT	13,202 MT

Operations

Orcopampa produced 40,682 oz of gold during 3Q2002, which represents an increase of 6% when compared to 38,067 oz of gold in the same quarter of 2001. This production was at a cash cost of US$166.11/oz, US$ 16.02/oz higher than 3Q01, due to very important exploration activities in the Nazareno, Prometida and Natividad veins of the mine.

The Company is pleased to report that gold production at Antapite in 3Q2002 increased 27.3% to 17,516 oz of gold, compared to 13,390 oz in the corresponding quarter of 2001, at a cash operating cost of US$154.28/oz.

At Uchucchacua, a decrease in silver grade led to a 9.1% decrease in silver production, amounting to 2,338,941 oz of silver during 3Q2002, from 2,572,779 oz of silver in 3Q2001. This decrease in ore grade, led to an increase in the cash operating cost at Uchucchacua during 3Q2002, which was US$3.13/oz of silver, compared to US$2.77/oz of silver during 3Q 2001.

Buenaventura's total production during 3Q2002, which includes 100% of its operating units, 78.06% of the production of the Ishihuinca and Antapite mines, 34.58% of the production of El Brocal, and 100.0% of the production at CEDIMIN, was as follows:

	3Q02	3Q01	Var.
Gold	65,217 oz	60,191 oz	+8.3 %
Silver	2,913,442 oz	3,347,298 oz	-13.0 %
Zinc	7,131 MT	7,790MT	-8.5 %
Lead	3,246 MT	3,413MT	-4.9 %

Earnings

Earnings per ADS for the three-month period ended September 30, 2002 were US$0.53, compared to US$0.30 in the corresponding period of 2001.

Non-consolidated affiliates

Buenaventura's income from non-consolidated affiliates, attributable mainly to Yanacocha, was S/. 93.0 million in 3Q2002, representing a 63% increase compared to S/. 57.0 million in the corresponding quarter of 2002. This increase was due to an increase of 15% in the price of gold sold, which during 3Q2002 was US$314/oz of gold, compared to US$273/oz of gold in the same period of 2001, as well as to an increase in gold production.

During this quarter, Yanacocha's production increased 23.3% to 638,870 oz of gold (278,867 oz of which represents Buenaventura's share) in 3Q2002, from 518,015 oz (226,114 oz of which represents Buenaventura's share) in the corresponding quarter of 2001. On the other hand, the cash operating cost was US$125/oz of gold during 3Q2002, compared to US$124/oz of gold during 3Q2001.

The above-mentioned production and costs, confirm that Yanacocha is performing as forecast.

Dividends

Buenaventura's Board meeting, held on October 22, 2002, approved:

• A cash dividend of S/. 0.32/share, or S/. 0.64/ADS.
• A dividend of 1 common share of Sociedad Minera el Brocal S.A. to holders of 100 shares of Buenaventura, or of a fraction of 100 shares of Buenaventura.
