OPERATING REVENUE

In 3Q06, net sales were US$122.1 million, a 95% increase when compared to the
US$62.7 million reported in 3Q05 mainly due to higher volumes of gold and silver
sold, as well as an increase in the realized prices of zinc, silver and lead.

Royalty income during 3Q06 totaled US$11.1 million, a 8% increase when compared
to the US$10.4 million reported in 3Q05. This was due to higher sales at
Yanacocha, best explained by the higher realized gold prices.

(*) Considering 100% equity share in INMINSUR

At Orcopampa (100%), total gold production in 3Q06 was 62,540 ounces, a 4%
increase when compared to the 60,133 ounces reported in 3Q05 due to a higher
grade and recovery rate (see appendix 2). Accumulated gold production was
188,268 ounces, an 8% increase when compared to 2005 (174,233 ounces).

Cash operating cost during 3Q06 was US$153/oz, 14% higher when compared to 3Q05.
This was mainly explained by higher consumption of support materials and
contractor expenses for ventilation work, as well as higher royalties paid to
the government.

Total royalties paid to the government at Orcopampa in 3Q06 were US$0.22
million.

At Uchucchacua (100%), total silver production during 3Q06 was 2,628,593 ounces,
in-line with 3Q05. Accumulated silver production was 7,233,823 ounces, a 6%
decrease when compared to 2005 (7,700,196 ounces).

Cash operating cost in 3Q06 increased 75% from $2.54/oz in 3Q05 to US$4.45/oz.
This was best explained by:

     1.   Higher supply consumption, mainly reagents for the new cyanidation
          plant and support materials.
     2.   Higher contractor expenses for preparation in the Huantajalla area
          (Raise Borer and Raise Climber).
     3.   Higher commercial treatment charge escalators and deductions explained
          by higher zinc and silver prices, partially offset by higher lead and
          zinc by-product credits.

Total royalties paid to the government at Uchucchacua in 3Q06 were US$0.23
million.

At Antapite (100%), total production in 3Q06 was 26,141 ounces of gold, in-line
with 3Q05 production. Accumulated gold production was 78,925 ounces, a 1%
increase when compared to 78,145 ounces in 2005.

Gold cash operating cost in 3Q06 was US$253/oz, a 17% increase when compared to
US$216/oz in 3Q05. This increase was due to higher prices for mine contractor
labor, as well as services and maintenance for mine operations.

Total royalties paid to the government at Antapite in 3Q06 were US$0.16 million.

At Colquijirca (34.29%), total zinc production was 15,128 MT in 3Q06, a 4%
increase when compared to 14,540 MT in 3Q05. Total silver production during 3Q06
was 2,599,118 ounces, a 142% increase when compared to the 1,073,779 ounces in
3Q05 due to a significant increase in the ore grade (Appendix 2).

For the nine-month 2006 period, total zinc production was 46,795 MT, a 14%
increase when compared to the same period of 2005 (41,003 MT). In the case of
silver, total production increased 155%, from 2,829,531 ounces in 2005 to
7,224,584 ounces in 2006.

Zinc cash operating costs decreased 27% from US$777 per MT in 3Q05 to US$571 per
MT in 3Q06. This was due to a significant silver and lead by-product credit
contribution despite higher commercial treatment expenses as a result of higher
prices.

Total royalties paid to the government at Colquijirca in 3Q06 were US$1.06
million.

OPERATING EXPENSES

General and administrative expenses for 3Q06 were US$8.4 million, a 17% decrease
compared to the US$10.1 million reported in 3Q05. This decrease was mainly due
to a lower Long-Term Compensation Program provision. Accumulated general and
administrative expenses for the nine-month period were US$25.8 million, a 16%
increase when compared to the US$22.2 million reported in the same period of
2005.

EXPLORATION COSTS IN NON-OPERATIONAL MINING SITES

Exploration costs in non-operating areas during 3Q06 were US$8.6 million, a 28%
increase compared to US$6.7 million during 3Q05. The main efforts were focused
at the Marcapunta, La Zanja and Los Pircos projects. Accumulated exploration
costs in non-operating areas during the first nine-months of 2006 were US$24.5
million a 30% increase when compared to comparable period (US$18.9 million).

OPERATING INCOME

Operating income in 3Q06 was US$67.6 million, a 241% increase compared to
US$19.8 million in 3Q05. This result was mainly due to the 83% increase in
operating revenues, which largely offset the 37% increase in the total cost of
operations.

For the nine-month period 2006, operating income was US$212.1 million a 192%
increase when compared to the US$72.6 million reported in the same period of
2005.

SHARE IN AFFILIATED COMPANIES

Buenaventura's income from non-consolidated affiliates was US$64.8 million
during 3Q06, an increase of 17% when compared to the US$55.5 million reported in
3Q05. This increase is explained by the higher contribution from Cerro Verde
(US$22.6 million). Yanacocha's contribution for this quarter was US$41.6
million. For the nine-month period of 2006, income from non-consolidated
affiliates was US$273.3 million, an increase of 83% compared to the US$149.4
million reported in 2005.

At Yanacocha (43.65%), 3Q06 gold production was 605,139 ounces of gold, a
decrease of 21% when compared to 3Q05 (763,615 ounces). Gold production for the
first nine-month period of 2006 was 2,156,168 ounces, a decrease of 5% when
compared to the 2,268,717 ounces reported in the first nine months of 2005. It
is important to mention that the Company continues to project full-year
production of 2.6 million ounces.

Gold cash cost at Yanacocha during 3Q06 was US$217/oz, which represented a 47%
increase compared to a gold cash cost of US$148/oz in 3Q05. This is explained by
an increase in consumable prices, as well as higher workers participation and
royalties to third parties.

Net income at Yanacocha during 3Q06 was US$96.9 million, a 15% decrease when
compared to the 3Q05 figure (US$114.4 million). For the nine-month period 2006,
net income was US$467.4 million, an increase of 46% compared to the US$320.7
million reported in 2005.

In 3Q06, EBITDA was US$200.5 million, a decrease of 4% compared to 3Q05
(US$209.0 million). This decrease was due to the lower volume of gold sold
despite the higher realized gold prices which increased from US$439/oz in 3Q05
to US$619/oz in 3Q06. Accumulated EBITDA in the first nine-months of 2006 was
US$816.6 million, an increase of 36% when compared to the US$599.2 million
reported in the same period of 2005.

Yanacocha distributed US$300 million in shareholders dividends during 3Q06.

CAPEX for 3Q06 was US$55.6 million, a 6% decrease when compared to US$59.1 in
3Q05.

At Cerro Verde (18.50%), 3Q06 copper production was 24,501 MT a 2% increase when
compared to 3Q05 (24,131 MT). For the nine-month period 2006 copper production
totaled 70,840.

Net sales at Cerro Verde increased 102% from US$92.9 million in 3Q05 to US$187.4
million in 3Q06. Accumulated net sales for 2006 were US$486.6 million, which
represented an increase of 103% compared to 3Q05 (US$240.0 million) MT due
mainly to higher realized copper prices.

In 3Q06, net income reached US$125.1 million, a 155% increase compared to 3Q05
(US$49.1 million). For the nine-month period of 2006 net income was US$342.7
million, a 186% increase compared to 2005 (US$119.8 million).

CAPEX for 3Q06 totaled US$112.6 million, of which US$108.0 million was allocated
towards the construction of the Primary Sulfide Project.

NET INCOME

This quarter, Buenaventura's net income was US$82.4 million, representing
US$0.65 per ADS, a 66% increase when compared to the US$49.5 million reported
(US$0.39 per ADS) in 3Q05. This was mainly due to higher operating revenues, as
well as the important contribution from Cerro Verde, which offset the decrease
in Yanacocha's net income.

Accumulated net income for 2006 was US$350.1 million (US$2.75 per ADS), an
increase of 85% when compared to US$189.2 million (US$1.50 per ADS) in 2005.

HEDGING OPERATIONS

The total hedge book mark-to-market value as of September 30, 2006 was a
negative US$526.4 million (US$630.5 million as of June 2006).

During 3Q06, the Company executed 92,308 ounces of silver in derivative
instruments completing all of its silver commitments.

EXPLORATIONS UPDATE

TANTAHUATAY

After several years working on social issues in the area, the company has
received Community support for the Tantahuatay project at Cajamarca, where
approximately 100 local Chugur Community workers are collaborating on-site with
road work, trenching, sampling and environmental rehabilitation.

Infill drilling with three rigs at the Cienaga prospect in Tantahuatay, confirms
lateral and depth continuity of the oxide-gold deposit. Results to date include:

C- 52 :      89.0m    @  1.54 g/t  of gold  with  83 % cyanide extraction
C- 57 :     120.0m    @  2.06 g/t  of gold  with  89 % cyanide extraction

EL MILAGRO

A polymetallic discovery has been made at the El Milagro prospect, located in
the Huancavelica and Ayacucho regions; which is easily accessible from the
Pisco-Ayacucho road and with friendly relationships with local communities. A
land position of 7,400 hectares is secured where high-level intrusives and a
volcanic vent pierce through limestone producing four areas of zinc(Zn),
lead(Pb) and silver(Ag) replacement deposits. Current diamond drilling with four
rigs has given encouraging intercepts for the Genoveva ore shoot, such as:

EM-02:   9.0 m   @   8.28 % Zn,   1.56 % Pb      and   0.86 oz/t Ag
EM-05:   8.6 m   @   8.42 % Zn,   2.44 % Pb      and   4.54 oz/t Ag
EM-14:   9.0 m   @   3.21 % Zn,   6.71 % Pb      and   12.93 oz/t Ag

Preliminary metallurgical tests show good results for selective flotation.

ORCOPAMPA

     o    The auxiliary shaft to improve ventilation and ore transport in the
          Prometida area commenced during the second quarter and is currently
          13% completed. The specialized contractor for the construction has
          been selected and total drifting at the end of 3Q06 was 380m. Total
          expected investment is US$3.7 million.

          MT to 1,800 MT commenced in May 2006, while the completion date has
          been extended to December 2006. This expansion considers the addition
          of new grinding and milling (SAG mill of 15x11). At the end of 3Q06
          this project is 50% complete. The total expected investment is US$4.7
          million.

     o    The expansion of tailing dam Number 4 commenced in July. Completion is
          expected by the end of 2006 with a total investment of US$5.9 million.

MARCAPUNTA

     o    In August, exploration activities at the Marcapunta Oeste project were
          suspended due to flooding. Pumping and drainage are currently in
          progress. It is important to mention that the flooding will only
          affect the underground activities of the Marcapunta Oeste project. The
          surface drilling program at Marcapunta Oeste will not be affected, nor
          will the exploitation activities at Colquijirca's current operations,
          or the exploration activities at Marcapunta Norte
