                    COMPANIA DE MINAS BUENAVENTURA ANNOUNCES
                           FOURTH QUARTER 2006 RESULTS

Lima, Peru, February 28, 2007 - Compania 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 fourth quarter of 2006. 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, Chief Executive Officer of Buenaventura stated: "We are
pleased to report a very good performance from our direct operations for the
quarter. As a result, operating income was US$108.7 million, 328% higher than
the figure recorded in 4Q05. This increase was explained by higher sales
revenues, which partially offset the lower contribution from non-consolidated
affiliates.

Net income in 4Q06 was US$78.8 million, or US$0.62 per ADS, which represents a
decrease of 19% when compared to 4Q05.

EBITDA from Buenaventura's direct operations was US$110.1 million, 190% higher
than the figured achieved in 4Q05."

     OPERATING REVENUE

In 4Q06, net sales were US$179.3 million, a 122% increase when compared to the
US$80.7 million reported in 4Q05 mainly due to higher volumes of silver, lead,
zinc and gold sold, as well as an increase in the realized prices of zinc,
silver and lead.

Royalty income during 4Q06 totaled US$9.2 million, a 41% decrease when compared
to the US$15.8 million reported in 4Q05. This was due to lower sales at
Yanacocha.

(*)  Considering 100% equity share in INMINSUR

At Orcopampa (100%), total gold production in 4Q06 was 65,624 ounces, an 11%
increase when compared to the 58,948 ounces reported in 4Q05 mainly due to a
higher grade (Appendix 2). Accumulated gold production was 254,631 ounces, a 9%
increase when compared to 2005 (233,182 ounces).

Cash operating cost during 4Q06 was US$155/oz, 8% higher when compared to 4Q05
(US$143/oz). This was best explained by an increase in tunneling and diamond
drilling, as well as higher reagent prices for the cyanidation plant. Cash
operating cost for 2006 was US$145/Oz, 7% higher than the figure reported for
2005 (US$135/Oz).

Total royalties paid to the government at Orcopampa in 4Q06 were US$0.7 million.
For 2006, royalties totaled US$2.1 million.

At Uchucchacua (100%), total silver production during 4Q06 was 2,458,477 ounces
a 2% decrease when compared to 4Q05 (2,513,737), mainly due to lower grade (15.2
Oz/ST in 4Q06 versus 16.8 Oz/ST in 4Q05). Accumulated silver production was
9,692,300 ounces, a 5% decrease when compared to 2005 (10,213,933 ounces).

Cash operating cost in 4Q06 increased 52% from $3.65/oz in 4Q05 to US$5.55/oz.
This was best explained by:

    1.  Higher contractor expenses for ventilation facilities (Raise Borer and
        Raise Climber), in the Huantajalla area, which was completed in December
        2006

    2.  Higher reagent consumption for the new cyanidation plant

    3.  Higher royalties paid to the government

    4.  Lower silver content due to lower silver grade

Cash operating cost for 2006 was US$4.50/Oz, 39% higher than the figure reported
for 2005 (US$3.23/Oz).

Total royalties paid to the government at Uchucchacua in 4Q06 were US$1.03
million. For 2006, royalties totaled US$2.7 million.

----------
(1)  Production includes 100% of operating units, 100% of CEDIMIN and 34.29% of

<PAGE>

At Antapite (100%), total production in 4Q06 was 24,444 ounces of gold, a
decrease of 5% when compared to 4Q05 (25,787 ounces), mainly due to a 6%
decrease in the gold grade from 0.59 Oz/ST to 0.56 Oz/ST. Accumulated gold
production was 103,370 ounces, in-line with 2005 production.

Gold cash operating cost in 4Q06 was US$291/Oz, a 35% increase when compared to
US$216/Oz in 4Q05. This increase was due to

    1.  The lower gold content due to lower grade

    2.  Higher diesel consumption for thermal energy generation and an increase
        in reagent prices for the cyanidation plant

    3.  An increase in contractor expenses for operational maintenance

Cash operating cost for 2006 was US$246/Oz, 18% higher than the figure reported
for 2005 (US$209/Oz).

Total royalties paid to the government at Antapite in 4Q06 were US$0.26 million.
For 2006, royalties totaled US$0.7 million.

At Colquijirca (34.29%), total zinc production was 18,906 MT in 4Q06, a 17%
increase when compared to the 16,147 MT reported in 4Q05 due to an increase in
tonnage treated despite the lower grade. Total silver production during 4Q06 was
3,044,927 ounces, a 95% increase when compared to the 1,565,409 ounces reported
in 4Q05 due to a significant increase in the ore grade, as well as higher ore
treated (Appendix 2).

For 2006, total zinc production was 65,700 MT, a 15% increase when compared to
the same period of 2005 (57,151 MT). In the case of silver, total production
increased 134% from 4,394,940 ounces in 2005 to 10,269,511 ounces in 2006.

Zinc cash operating costs for 4Q06 was a negative US$190 per MT due to a
significant silver and lead by-product credit contribution. For 2006, cash
operating cost was US$233 per MT, a 64% decrease when compared to the US$643 per
MT reported in 2005.

Total royalties paid to the government at Colquijirca in 4Q06 were US$2.9
million.

     OPERATING EXPENSES

General and administrative expenses for 4Q06 were US$11.1 million, a 4% decrease
compared to the US$11.5 million reported in 4Q05. Accumulated general and
administrative expenses for 2006 were US$36.6 million, a 6% increase when
compared to the US$34.4 million reported in 2005.

     EXPLORATION COSTS IN NON-OPERATIONAL MINING SITES

Exploration costs in non-operating areas during 4Q06 were US$11.9 million, a 41%
increase compared to the US$8.4 million reported in 4Q05. The main efforts were
focused at the Marcapunta, La Zanja and El Milagro projects. Accumulated
exploration costs in non-operating areas during 2006 were US$36.2 million, a 30%
increase when compared to 2005 (US$27.8 million).

<PAGE>

     OPERATING INCOME

Operating income in 4Q06 was US$108.7 million, a 328% increase compared to the
US$25.4 million reported in 4Q05. This result was mainly due to the 92% increase
in operating revenues, which largely offset the increase in the total cost of
operations and operating expenses.

For 2006, operating income was US$317.3 million, a 218% increase when compared
to the US$99.7 million reported in 2005.

     SHARE IN AFFILIATED COMPANIES

Buenaventura's income from non-consolidated affiliates was US$43.0 million in
4Q06, a decrease of 66% when compared to the US$125.0 million reported in 4Q05.
This decrease is explained by the lower contribution from Cerro Verde (US$18.9
million) and Yanacocha (US$25.3 million). For 2006, income from non-consolidated
affiliates was US$313.2 million, an increase of 19% compared to the US$264.0
million reported in 2005.

At Yanacocha (43.65%), 4Q06 gold production was 456,032 ounces of gold, a
decrease of 57% when compared to 4Q05 (1,064,371 ounces). Gold production for
2006 was 2,612,199 ounces, a decrease of 22% when compared to the 3,333,088
ounces reported in 2005. For 2007, the Company estimates full-year production of
1.6 million ounces.

Cash cost at Yanacocha during 4Q06 was US$261/oz, which represented a 75%
increase compared to a cash cost of US$149/oz in 4Q05. This is explained by the
decrease in gold production due to lower grade, an increase in the price of
diesel, cyanide, lime and other commodities, as well as higher worker
participation and royalties to third parties. For 2006, cash cost was US$202/oz,
a 35% increase when compared to 2005.

Net income at Yanacocha during 4Q06 was US$58.1 million, a 72% decrease when
compared to the 4Q05 figure (US$204.8 million). For 2006, net income was
US$525.4 million, similar to the figure reported in 2005.

In 4Q06, EBITDA was US$113.6 million, a decrease of 68% compared to 4Q05
(US$351.7 million). This decrease was due to the lower volume of gold sold
despite the higher realized gold prices, which increased from US$484/oz in 4Q05
to US$614/oz in 4Q06. Accumulated EBITDA for 2006 was US$930.2 million, a
decrease of 2% when compared to the US$950.9 million reported in 2005.

CAPEX for 4Q06 was US$87.9 million, a 45% increase when compared to US$60.5
reported in 4Q05, mainly devoted to the construction of the Gold Mill to treat
transitional ore.

At Cerro Verde (18.50%), 4Q06 copper production was 29,736 MT, a 24% increase
when compared to 4Q05 (24,072 MT). For 2006, copper production totaled 100,573
MT, 8% higher than the figured reported in 2005 (93,550 MT).

In 4Q06, net income reached US$101.9 million, a 10% decrease compared to 4Q05
(US$113.6 million), best explained by the US$40 million expense related to the
construction of a water treatment plant as part of the agreement between the
Company and the Committee for the Defense of the Interests of Arequipa. For
2006, net income was US$444.6 million, a 90% increase compared to 2005 (US$233.4
million).

Net sales at Cerro Verde increased 52% from US$118.9 million in 4Q05 to US$181.1
million in 4Q06. Accumulated net sales for 2006 were US$667.7 million, an
increase of 86% compared to 4Q05 (US$358.9 million), mainly due to higher
realized copper prices (US$3.21/Lb in 4Q06 versus US$1.95/Lb in 4Q05).

<PAGE>

CAPEX for 4Q06 totaled US$110.1 million, of which US$80.8 million was allocated
to the completion of the Primary Sulfide Project. We expect full capacity
operations prior to the end of first half 2007.

     NET INCOME

This quarter, Buenaventura's net income was US$78.8 million, representing
US$0.62 per ADS, a 19% decrease when compared to the US$96.7 million reported
(US$0.79 per ADS) in 4Q05. This was mainly due to lower contribution from
non-consolidated affiliates. This figure includes a provision of US$1.8 million
for the "Voluntary Contribution for Social Responsibility".

Accumulated net income for 2006 was US$428.1 million (US$3.36 per ADS), an
increase of 48% when compared to US$288.4 million (US$2.27 per ADS) in 2005.

     HEDGING OPERATIONS

The total hedge book mark-to-market value as of December 31, 2006 was a negative
US$585.66 million (US$526.4 million as of September 2006).

Per a filing with the SEC in January 2007, the Company restructured its hedge
book as shown in Appendix 4.

     EXPLORATIONS UPDATE

Greenfield and Brownfield exploration expenditures during 2006 totaled US$ 36.2
million, of which US$10.2 was spent on the acquisition and maintenance of
properties. Buenaventura directly controls 286,845 hectares, and through joint
ventures or lease/option agreements an additional 119,597 hectares for a total
of 406,442 hectares, excluding our own operations, Cerro Verde and Yanacocha.

Exploration projects currently being licensed for start-up of new mining
production in 2007 are Marcapunta by Soc. Minera El Brocal, and Pozo Rico and
Poracota by Buenaventura. Minera La Zanja has successfully concluded its
exploration program and will complete its environmental impact study and seek
permitting to construct two open pits, and a heap-leach facility in 2008 for the
Pampa Verde and San Pedro Sur deposits.

During 2007 our exploration focus will be centered on the oxide-gold prospects
of Tantahuatay and Breapampa, the silver-rich, base-metal deposits of Hualgayoc,
Mallay and El Milagro, and the copper (molybdenum) porphyry at Trapiche.
Detailed programs and budgets await approval, but expenditures in the order or
US$ 20.0 million are anticipated.

     PROJECT DEVELOPMENT

UCHUCCHACUA

    o   During 4Q06, the deepening of the Master Shaft reached level 3990 (67%
        of the total), where a sub-station for shaft equipment is currently
        under construction. From this level, two ramps are being developed in
        the Carmen and Socorro mines, which are expected to reach level 3920
        during 1Q08. As of December 2006, investment was US$3 million out of a
        budget of US$10.3 million.

    o   As of January 2007, the Pozo Rico project commenced operations
        contributing 5.3 million silver ounces to the Uchucchacua mine reserves.

ORCOPAMPA

    o   The deepening of the Prometida and Nazareno mines at level 3340 is
        currently in its final stage, which includes an integration adit and
        ventilation facilities. This project is expected to be completed by the
        end of 2007. The project will improve the communication and transport or
        both personnel and materials between the mines. Total investment for
        this project is expected to be US$6.6 million.

    o   The expansion of the treatment plant to increase capacity from 1,200 MT
        to 1,800 MT is currently in the testing stage, treating small amounts of
        Poracota ore material. This facility will permit a good assessment of
        Poracota's ore metallurgical behavior. Total investment as of December
        2006 was US$4.6 million.

ANTAPITE

    o   The expansion of the Tailing Dam to increase capacity by 1.2 million DST
        (five additional years) began in May 2006, and is expected to be
        completed by the end of 2007, with a budgeted investment of US$7.9
        million (US$2.2 million expended as of December 2006).
