In 3Q07, net sales were US$188.2 million, a 54% increase when compared to the US$122.3 million reported in 3Q06 mainly due to higher volumes of lead and zinc sold, as well as an increase in the realized prices of all metals, especially gold, which was partially hedged in 2006, and lead. This was partially offset by a decrease in the volume of gold sold due to a higher gold stock of 12,272 ounces as of September 30, 2007, in addition to the lower silver production at Colquijirca.

Royalty income during 3Q07 totaled US$7.6 million, a 32% decrease when compared to the US$11.1 million reported in 3Q06. This was due to lower sales at Yanacocha.

(*) Including Cerro Verde

At Orcopampa (100%), total gold production in 3Q07 was 69,983 ounces, a 12% increase when compared to the 62,540 ounces reported in 3Q06 (Appendix 2) due to an increase in ore grade from 0.55 Oz/ST in 3Q06 to 0.60 Oz/ST in 3Q07. Accumulated gold production was 198,789 ounces, a 6% increase when compared to 2006 (188,267 ounces).

Cash operating cost during 3Q07 was US$167/oz, 10% higher when compared to 3Q06 (US$153/oz). This was best explained by higher exploration expenses due to an increase in diamond drilling labor, the impact of the Nuevo Sol appreciation on labor expenses, as well as higher supply prices.

Total royalties paid to the government at Orcopampa in 3Q07 were US$1.4 million.

Poracota, whose permits to begin production were recently obtained, produced 4,830 ounces of gold within a pilot production program during the quarter. Regular production will begin in January 2008.

At Uchucchacua (100%), total silver production during 3Q07 was 2,685,812 ounces a 2% increase when compared to 3Q06 (2,628,593 ounces). Total zinc production increased 84% from 1,204 MT in 3Q06 to 2,210 MT in 3Q07 due to higher zinc grade ore from lower levels of the mine. Accumulated silver production was 6,860,183 ounces, a 5% decrease when compared to 2006 (7,233,823 ounces), while zinc production increased 26% from 3,661 MT in the same period of 2006, to 4,623 MT in 2007.

Cash operating cost in 3Q07 decreased 4% from $4.45/oz in 3Q06 to US$4.29/oz. This was best explained by increased production as a result of higher silver recoveries, and an increase in by-product contribution.

Total royalties paid to the government at Uchucchacua in 3Q07 were US$1.2 million.

¹ Production includes 100% of operating units, 100% of CEDIMIN and 34.29% of El Brocal.

At Antapite (100%), total production in 3Q07 was 16,486 ounces of gold, a decrease of 37% when compared to 3Q06 (26,141 ounces), mainly due to a 36% decrease in gold grade from 0.60 Oz/ST to 0.38 Oz/ST. Accumulated gold production was 53,544 ounces, a 32% decrease when compared to 2006 (78,925 oz).

Gold cash operating cost in 3Q07 was US$431/Oz, a 70% increase when compared to US$253/Oz in 3Q06. This increase was explained by lower production due to the decrease in gold grade, as well as an increase in exploration expenses.

Total royalties paid to the government at Antapite in 3Q07 were US$0.3 million.

At Colquijirca (El Brocal) (34.29%), total zinc production for 3Q07 was 23,318 MT, a 54% increase when compared to the 15,129 MT reported in 3Q06 due to a 43% increase in ore mined. Total silver production during 3Q07 was 1,938,095 ounces, a 25% decrease when compared to the 2,599,118 ounces reported in 3Q06 due to normal silver grade production (5.78 oz/MT in 3Q07 compared to 8.02 oz/MT in 3Q06, higher than the average silver grade of the reserves).

Accumulated zinc production for the nine-month period of 2007 was 62,684 MT, a 34% increase when compared to the same period of 2006 (46,794 MT). In the case of silver, total production decreased 27% from 7,224,584 ounces in 2006 to 5,301,821 ounces in 2007.

Zinc cash operating cost for 3Q07 was a negative US$7 per MT due to an increase in the contribution of lead as a by-product.

Total royalties paid to the government at Colquijirca in 3Q07 were US$2.3 million.

General and administrative expenses for 3Q07 were US$13.7 million, a 63% increase compared to the US$8.4 million reported in 3Q06 due to a non-cash US$7.2 million provision for the Long-Term Compensation provision. General and administrative expenses for the accumulated period were US$35.3 million, a 38% increase when compared to the US$25.6 million reported in the same period of 2006.

Exploration costs at non-operational mining sites during 3Q07 were US$10.9 million, a 27% increase compared to the US$8.6 million reported in 3Q06. The main efforts were focused at the Marcapunta (US$1.8 million), Breapampa (US$1.2 million), El Milagro (US$1.5 million), Trapiche (US$0.7 million), Mallay (US$1.7 million) and Argentina (US$0.5 million) projects. Exploration costs at non-operating mining sites during the first nine-month period 2007 were US$31.3 million (26% at Colquijirca and Marcapunta), a 29% increase when compared to the same period of 2006 (US$24.3 million).

Operating income in 3Q07 was US$88.8 million, a 35% increase compared to the US$66.0 million reported in 3Q06. This result was mainly due to the US$51.0 million increase in operating revenues, despite the US$17.1 million increase in operating costs, US$11.0 million the operating expenses.

For the nine-month period 2007, operating income was US$260.9 million, a 25% increase when compared to the US$208.6 million reported in 2006.

During 3Q07, Buenaventura’s income from non-consolidated affiliates was US$67.8 million, an increase of 4% when compared to the US$65.0 million reported in 3Q06. This increase is explained by an 121% increase in contributions from Cerro Verde (US$50.1 million in 3Q07 versus US$22.6 million in 3Q06), which offset the 60% decrease in Yanacocha’s contribution (US$16.7 million in 3Q07 versus US$41.7 million in 3Q06). Accumulated 2007 income from non-consolidated affiliates totaled US$171.6 million, a 36% decrease compared to the US$268.4 million reported in 2006.

YANACOCHA

At Yanacocha (43.65%), 3Q07 gold production was 373,150 ounces of gold, a decrease of 38% when compared to 3Q06 (605,139 ounces). Gold production for the nine-month 2007 period was, as planned, 1,093,910 ounces, a decrease of 49% compared to the 2,156,168 ounces reported in the comparable period of 2006. The Company estimates full-year production of approximately 1.6 million ounces.

Cash cost at Yanacocha during 3Q07 was US$369/oz, which represented a 70% increase from the US$217/oz reported in 3Q06. This is explained by the decrease in gold production and the higher proportion of waste and tons mined. For 2007, the Company estimates an average cash cost of US$340-US$360/oz.

Net income at Yanacocha during 3Q07 was US$39.5 million, a 59% decrease when compared to the 3Q06 figure (US$96.9 million). Accumulated net income for 2007 was US$123.5 million, 74% lower than the same period of 2006 (US$467.4 million).

During 3Q07, EBITDA totaled US$100.8 million, a decrease of 50% compared to 3Q06 (US$200.5 million). This decrease was due to the 38% decrease in volume of gold sold despite higher realized gold prices, which increased from US$619/oz in 3Q06 to US$682/oz in 3Q07. Accumulated 2007 EBITDA was US$300.8 million, a decrease of 63% when compared to the US$816.6 million reported in 2006.

CAPEX for 3Q07 was US$88.8 million, a 60% increase when compared to the US$55.6 reported in 3Q06, mainly devoted to the construction of the Gold Mill project to be completed by year-end.

CERRO VERDE

At Cerro Verde (18.50%), 3Q07 copper production was 77,636 MT, a 217% increase compared to 3Q06 (24,501 MT). This increase is explained by the impact of the new primary sulfide processing plant, which operated at full capacity during the quarter. Copper production for the accumulated 2007 period totaled 193,004 MT, 172% higher than the figured reported in the same period of 2006 (70,840 MT).

During 3Q07, net income was US$264.2 million, a 111% increase compared to 3Q06 (US$125.1 million), best explained by higher sales, which increased 221% from US$187.4 million in 3Q06 to US$601.1 million in 3Q07 as a result of the aforementioned increase in production.

Accumulated 2007 net income was US$639.7 million, an 87% increase compared to the US$342.7 million reported in the same period of 2006. Accumulated net sales for 2007 were US$1,371.8 million, an increase of 182% compared to 2006 (US$486.6 million).

CAPEX in 3Q07 totaled US$12.4 million.

This quarter, Buenaventura’s net income was US$99.9 million, representing US$0.79 per ADS, a 23% increase when compared to the US$81.2 million reported (US$0.64 per ADS) in 3Q06. This increase was explained by the higher contribution from Buenaventura’s direct operations, in addition to contributions from Cerro Verde (US$50.1 million in 3Q07 versus US$22.6 million in 3Q06), which completely offset the decreased contribution from Yanacocha (US$16.7 million in 3Q07 versus US$41.7 million in 3Q06).

Net income for the nine-month period 2007 was US$151.0 million (US$1.19 per ADS), a decrease of 57% when compared to the US$347.5 million (US$2.7 per ADS) reported in the same period of 2006 due to the effect of the un-winding of the Company’s hedging position reported during the first half of the year.

The total hedge book mark-to-market value as of September 30, 2007 was a negative (US$380.6 million), compared to a negative (US$305.0 million) as of June 30, 2007.

UCHUCCHACUA

The deepening of the Carmen and Socorro mines include:

Carmen Mine: The construction of ramp 760 was completed in September as scheduled. The deepening of the Master Shaft is currently 98% complete and is expected to be completed by December 2007. The development at level 3990, which involves drifting 2,394 meters, is 22% complete and is expected to completed by August 2008.

Socorro Mine: The construction of ramp 626 is currently 61% complete, and is expected to be finished by 1Q08.

ORCOPAMPA

The deepening of the Master Shaft (located in the Nazareno mine) from level 3390 to level 3290 was completed. As the mineralization continues at lower levels of the mine, the deepening shaft will continue until level 3230. Total investment for this project as of September 30, 2007 was US$7.4 million.

The sinking of the Prometida Shaft from level 3590 to level 3290 is 50% complete.

The expansion of tailing dam Number 4, to increase capacity to 1.3 million DST, is currently 95% complete. To date, investment has totaled US$5.4 million. Total estimated investment for this project is $5.8 million to be completed in 4Q07.

The construction of the project to retreat tailings from the older Tailing Dam Number 3 started in September 2007. Completion is expected by 2Q08. This will allow the recovery of approximately 53,000 gold ounces and 190,000 silver ounces in two years, with an estimated investment of US$5.7 million.
