Compania De Minas Buenaventura Announces Second Quarter 2008 Results

LIMA, Peru, July 30 /PRNewswire-FirstCall/ -- 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 second quarter 2008. 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:  

"Net income in 2Q08 was US$121.7 million, or US$0.48 per ADS, which represents a significant increase when compared to 2Q07, but in-line with net income after adjusting for the non-recurring expenses reported in 2Q07.

Operating income in the second quarter was US$92.7 million, in-line with the figure reported in 2Q07, while EBITDA from Buenaventura's direct operations totaled US$106.3 million, 4% lower than the figure achieved in 2Q07. This decrease is explained by the higher costs reported at most of the Company's mines. Total EBITDA during the second quarter increased 37% due to higher contribution from Yanacocha and Cerro Verde."

Operating Revenue

During 2Q08, net sales were US$204.3 million, a 13% increase when compared to the US$181.4 million reported in 2Q07, mainly due to higher volumes of silver and zinc sold, as well as an increase in the realized prices of gold and silver. This was partially offset by a decrease in the volume of lead sold, as well as lower zinc prices.

Royalty income during 2Q08 totaled US$12.1 million, a 90% increase when compared to the US$6.3 million reported in 2Q07. This was due to higher sales at Yanacocha.

Net sales for the six-month period of 2008 were US$416.3 million, a 25% increase compared to the same period of 2007 (US$332.3 million), while royalty income was US$26.3 million, a 79% increase when compared to US$14.7 million in 2007.

Production and Operating Costs

Buenaventura's equity production(1) during 2Q08 was 103,651 ounces of gold, 6% higher than the 98,177 ounces reported in 2Q07; and 3,937,250 ounces of silver, an 11% increase when compared to the 3,539,363 ounces reported in 2Q07.

Equity production(1) for the accumulated six-month period was 202,511 ounces of gold and 7,860,151 ounces of silver. This represented an increase of 5% in gold production (192,525 ounces in 2007), and a 9% increase in silver production compared to 2007 (7,244,352 ounces).

At Orcopampa (100%), total gold production in 2Q08 was 70,019 ounces, a 7% increase when compared to the 65,587 ounces reported in 2Q07. Accumulated gold production was 132,214 ounces, a 3% increase when compared to 2007 (128,805 ounces).

Cash operating costs during 2Q08 were US$249/oz, 53% higher when compared to 2Q07 (US$163/oz). This was explained by:

     1. An increase in the consumption of mining support supplies.     2. The appreciation of the PEN(2)   

At Poracota, gold production in 2Q08 was 11,396 ounces, while cash operating costs were US$543/oz.

Total royalties paid to the government at both Orcopampa and Poracota in 2Q08 were US$1.7 million (US$1.3 in 2Q07).

At Uchucchacua (100%), total silver production during 2Q08 was 2,897,646 ounces, a 34% increase when compared to 2Q07 (2,168,184 oz), mainly due to a 16% increase in recovery rates and a 14% increase in ore mined. Likewise, zinc production increased 82% (2,216 MT in 2Q08 vs. 1,220 MT in 2Q07), while lead production increased 36% (2,149 MT in 2Q08 vs. 1,583 MT in 2Q07).

Accumulated production for the six month period 2008 was: 5,798,800 oz of silver, 39% higher than in 2007 (4,174,372 oz); 5,203 MT of zinc, an increase of 116% when compared to 2007 (2,414 MT) and 2,149 MT of lead, 35% lower than in 2007 (3,304 MT).

Cash operating costs in 2Q08 were US$7.18/oz, a 24% increase compared to $5.79/oz in 2Q07. This was best explained by:

     1. The lower lead and zinc by-product contribution due to lower prices        and commercial terms.     2. An increase in diamond drilling (10,163m in 2Q08 vs. 6,313m in 2Q07)        and drifting work (7,693m in 2Q08 vs. 9,320m in 2Q07).     3. The appreciation of the PEN.   

Total royalties paid to the government at Uchucchacua in 2Q08 were US$1.6 million (US$0.7 in 2Q07).

At Antapite (100%), total production in 2Q08 was 9,546 ounces of gold, a decrease of 48% when compared to 2Q07 (18,395 ounces), mainly due to a 51% decrease in gold grade from 0.39 Oz/ST to 0.19 Oz/ST. Accumulated gold production was 24,408 ounces, a 34% decrease when compared to 2007 (37,058 oz).

Gold cash operating costs in 2Q08 were US$695/Oz, a 93% increase when compared to US$360/Oz in 2Q07. This increase was due to:

     1. The lower gold content due to lower grades.     2. An increase in diamond drilling (5,822m in 2Q08 vs. 4,791m in 2Q07).   

Total royalties paid to the government at Antapite in 2Q08 were US$0.2 million (US$0.2 in 2Q07).

At Colquijirca (El Brocal) (34.29%), total zinc production was 23,845 MT in 2Q08, a 17% increase when compared to the 20,382 MT reported in 2Q07 due to an increase in ore mined. Total silver production during 2Q08 was 1,172,068 ounces, a 9% decrease when compared to the 1,289,448 ounces reported in 2Q07 due to a lower silver grade.

For 1H08, total zinc production was 44,850 MT, a 14% increase when compared to the same period of 2007 (39,366 MT). In the case of silver, total production decreased 29% from 3,363,726 ounces in 2007 to 2,388,396 ounces in 2008.

Zinc cash operating costs for 2Q08 were US$327 per MT, an increase of 26% when compared to 2Q07 (US$259 per MT), due a decrease in lead and silver contribution.

In Marcapunta, copper production for 2Q08 was 1,918 MT and 3,297 MT accumulated for 2008.

Total royalties paid to the government at Colquijirca in 2Q08 were US$1.0 million (US$1.4 in 2Q07).

Operating Expenses

General and administrative expenses for 2Q08 were US$9.7 million, a 27% decrease compared to the US$13.3 million reported in 2Q07 due to a lower Long- Term Compensation provision (US$0.4 million in 2Q08 vs. US$4.6 million in 2Q07). General and administrative expenses for 1H08 were US$37.2 million, a 73% increase when compared to the US$21.6 million reported in the same period of 2007.

Exploration Costs in non-operational mining sites

Exploration costs at non-operational mining sites during 2Q08 were US$15.7 million, a 38% increase compared to the US$11.4 million reported in 2Q07. The main efforts were focused at the Marcapunta (US$2.8 million), Mallay (US$2.5 million), La Zanja (US$2.0 million) and La Llave (US$1.3 million) projects. Exploration costs at non-operating mining sites during 1H08 were US$27.2 million, a 33% increase when compared to the same period in 2007 (US$20.4 million).

-- Environmental Impact Studies have been presented for the La Zanja and Mallay projects to the regional and national authorities. Both projects had successful Public Hearings on July 3, 2008 and July 24, 2008, respectively. The Company expects final permitting to take place early next year. La Zanja and Mallay are currently upgrading engineering designs, developing local infrastructure and building mutual trust with the corresponding communities.

-- At the Trapiche project, a new agreement was signed with the Mollebamba community. Mollebamba voted in favor of a long-term lease agreement for 2,500 hectares in surface rights. Exploration drilling will commence in August to extend the project 30,000 m into the Southeast Trapiche porphyry and the Millocucho skarns and porphyry.

-- At Tantahuatay, a new 400 m x 200 m zone of auriferous oxide breccia was found with 39 channel samples that averaged 0.58 g/t Au (96% CN soluble) and 9.20 g/t Ag. The corresponding environmental impact study was presented on July 8, 2008 to the regional and national authorities.

-- At the Pucagallo prospect in the Newmont's Brea Pampa project, two continuous channel samples over outcropping ledges gave the following gold oxide results:

                   37.50 m @ 1.80 g/t Au (84% CN soluble)                   14.40 m @ 1.05 g/t Au (70% CN soluble)     Operating Income  

Operating income in 2Q08 was US$92.7 million, a 1% decrease compared to the US$94.0 million reported in 2Q07. This result was mainly due to the previously mentioned increase in costs at the Company's mining operations.

For 1H08, operating income was US$195.4 million, a 14% increase when compared to the US$172.1 million reported in 1H07.

Share in Affiliated Companies

During 2Q08, Buenaventura's income from non-consolidated affiliates was US$98.6 million, an increase of 88% when compared to the US$52.4 million reported in 2Q07. This increase is explained by the US$43.3 million contribution from Yanacocha (US$9.5 million in 2Q08) and the US$55.3 million contribution from Cerro Verde (US$41.7 million in 2Q07). In 1H08, income from non-consolidated affiliates was US$244.3 million, an increase of 127% compared to the US$107.5 million reported in 2007.

Costs applicable to sales (CAS) at Yanacocha during 2Q08 were US$386/oz, which represented an 11% decrease from the US$436/oz reported in 2Q07. This is explained by the 39% increase in gold ounces sold (432,614 ounces in 2Q08 vs. 311,465 ounces in 2Q07).

Net income at Yanacocha during 2Q08 was US$99.6 million, a 578% increase when compared to the 2Q07 figure (US$14.7 million). Net income in 1H08 was US$285.8 million, 240% higher than the same period of 2007 (US$84.0 million).

During 2Q08, EBITDA totaled US$193.8 million, an increase of 221% compared to 2Q07 (US$60.5 million). This increase was due to an increase in volume of gold sold and higher realized gold prices, which increased from US$667/oz in 2Q07 to US$896/oz in 2Q08. EBITDA in 1H08 was US$493.5 million, an increase of 147% when compared to the US$200.0 million reported in 2007.
