Operating Revenue

During 1Q12, net sales were US$359.0 million, similar to the US$363.5 million reported in 1Q11. Lower base metal prices, as well as a decrease in silver, copper and zinc volume sold offset higher precious metal prices. It is important to mention that due to logistic constraints at the Callao Port and warehouses, lead-silver concentrate inventories tripled when comparing 1Q12 with 1Q11, representing a US$31 million increase at market value.

Royalty income increased 47%, from US$12.3 million reported in 1Q11 to US$18.1 million in 1Q12 due to higher revenues at Yanacocha.

Production and Operating Costs

Buenaventura’s equity production 1 in 1Q12 was 117,852 ounces of gold, in-line with the figures reported in 1Q11. Silver production in 1Q12 was 4.0 million ounces, a 14% increase when compared to the figure reported in 1Q11 (3.5 million oz) mainly due to higher production from Uchucchacua.
Equity Production 1    
        1Q12       1Q11       Var%  
Gold (oz)       117,852       116,270       1%  
Gold (oz) inc. Yanacocha       277,798       242,076       15%  
Silver (oz)       4,013,509       3,533,975       14%  
Lead ( MT)       4,907       3,092       59%

Orcopampa’s (100% owned by Buenaventura) production from the Chipmo mine in 1Q12 was 62,358 ounces, 15% lower than the 73,570 ounces reported in 1Q11 due to a lower tonnage treated and ore grade declines (See Appendix 2). The old tailings treatment produced 6,907 gold ounces (compared to 4,043 ounces in 1Q11). As a consequence, total gold production in 1Q12 was 69,265 ounces, 11% lower than the 77,614 ounces reported in 1Q11.

Cash operating cost in 1Q12 was US$463/oz, 24% higher when compared to 1Q11 (US$373/oz). This was mainly explained by:
    1.   The 12% decrease in gold ounces produced due to lower ore grades
2. A 20% increase in supply expenses: reagents (cyanide) and diesel
3. Contractor costs increased approximately 50% due to the 27% increase in drilling (7,803m vs. 6,765m) and the 13% increase in drifting work (5,518m vs. 4,879m).
4. These factors were partially offset by an increase in the by-product credit contribution explained by higher silver production and prices.

At Poracota, gold production in 1Q12 was 11,320 ounces, a 6% decrease when compared to 1Q11 (12,101 ounces) due to lower ore grade and a decrease in the recovery rate (See Appendix 2). Cash operating cost was US$1,257/oz, 28% higher than the figure reported in 1Q11 (US$982/oz), mainly explained by:
    1.   Contractor costs increased approximately 21% due to the increase of drifting work (19% higher vs. 1Q11).
2. A 62% increase in commercial deductions due to a temporary increase of arsenic content in the mine concentrate.

At Uchucchacua (100% owned by Buenaventura), total silver production in 1Q12 was 2.7 million ounces, a 10% increase when compared to 2.5 million ounces in 1Q11 due to higher tonnage treated, and an increase in the silver grade & recovery rate (See Appendix). Zinc production in 1Q12 was 2,439 MT, 28% higher than the figure reported in 1Q11 (1,902MT). In addition, lead production increased 11% (2,193 MT in 1Q12 vs. 1,974 MT in 1Q11).

__________________ 1 Production includes 100% of Buenaventura’s operating units, 100% of CEDIMIN, 53.06% of La Zanja and 53.78% of El Brocal.

Cash operating cost in 1Q12 was US$17.91/oz, a 20% increase compared to US$14.98/oz in 1Q11. This increase was primarily due to a:
    1.   23% increase in contractor expenses explained by higher wages and one-time bonuses for closing negotiations with unions. Last year, the effect of this expense was reflected in 2Q11.
2. Labor and supply expenses increased 13% and 14%, respectively.
3. An increase in commercial terms due to higher silver refining charges, as well as lower by-product credit contribution due to lower lead and zinc prices

At Julcani (100% owned by Buenaventura), total production in 1Q12 was 631,628 ounces of silver, an increase of 4% compared to 1Q11 (606,288 ounces), mainly due to a 3% increase in tonnage treated.

Silver cash operating cost in 1Q12 was US$12.77/oz, 15% higher than 1Q11 (US$11.10/oz), mainly explained by a 13% increase in contractors costs due to higher prices and drifting work increases.

At La Zanja (53.06% owned by Buenaventura) total production in 1Q12 was 26,329 ounces of gold, a 5% increase when compared to 1Q11 (25,151 ounces). Cash operating cost in 1Q12 was US$496/oz, 43% higher than 1Q11 (US$346 /oz) due to higher labor and contractor expenses, partially offset by higher silver by-product contribution.

At Tantahuatay (40% owned by Buenaventura) Total production in 1Q12 was 27,606 ounces of gold (11,042 ounces attributable to Buenaventura). Cash operating cost in 1Q12 was US$497/oz.

During 1Q12, El Brocal (53.76% owned by Buenaventura) produced 7,607 MT of zinc and 2,279 MT of lead. Silver production decreased 2% from 443,942 ounces in 1Q12 to 453,674 ounces in 1Q11. Zinc cash cost in 1Q12 was US$1,346/MT.

Copper production in 1Q12 was 5,614 MT, 25% lower than 1Q11 (7,473 MT). Copper cash cost was US$4,984/MT, 55% higher when compared to the US$3,220/MT reported in 1Q11 due to higher contractor expenses at Marcapunta.

General and Administrative Expenses

General and administrative expenses in 1Q12 were US$29.8 million, 76% higher than the figure reported in 1Q11 (US$17.0 million) due to a higher long-term compensation provision (US$7.3 million in 1Q12 vs. zero in 1Q11) and a US$3.8 million increase in worker´s profit sharing.

Exploration Costs in Non-Operational Mining Sites

Exploration costs at non-operational mining sites, which include care and maintenance, in 1Q12 were US$19.4 million, an 83% increase compared to the US$10.6 million reported in 1Q11. Buenaventura’s main exploration efforts were focused at the Tambomayo (US$3.0 million), San Gregorio (US$2.4 million), Breapampa (US$2.0 million), Mallay (US$2.0 million) and Trapiche (US$1.5 million) projects.

Operating Income

Operating income in 1Q12 was US$131.5 million, a 26% decrease compared to the US$178.4 million reported in 1Q11. This decrease was mainly due to the 15% increase in operating costs and an 81% increase in operating expenses, while revenues remained flat.

Share in Associated Companies

During 1Q12, Buenaventura’s share in associated companies was US$136.0 million, 20% higher than the US$112.9 million reported in 1Q11. Yanacocha’s contribution to these results increased 83%, from US$48.2 million in 1Q11 to US$88.2 million in 1Q12, while Cerro Verde’s contribution decreased 37% from US$71.0 million in 1Q11 to US$44.9 million in 1Q12.


At Yanacocha (43.65% owned by Buenaventura), 1Q12 gold production was 366,428 ounces of gold, 27% higher than the figure reported in 1Q11 (288,214 ounces).

Costs applicable to sales (CAS) at Yanacocha in 1Q12 were US$481/oz, 20% lower than the figure reported in 1Q11 (US$603/oz) due to lower operating costs, partially offset by higher worker´s participation.

Net income at Yanacocha in 1Q12 was US$202.0 million, a 82% increase compared to the 1Q11 figure (US$110.7 million).

Capital expenditures at Yanacocha were US$227.4 million in 1Q12.


At Cerro Verde (19.35% owned by Buenaventura), 1Q12 copper production was 63,295 MT, a 20% decrease when compared to 1Q11 (79,463 MT).

During 1Q12, Cerro Verde reported net income of US$232.3 million, a 37% decrease when compared to US$367.7 million in 1Q11. This was mainly due to a 23% decrease in sales revenues (US$568.8 million in 1Q12 versus US$740.9 million in 1Q11).

Capital expenditures at Cerro Verde in 1Q12 totaled US$82.2 million.

CANTERAS DEL HALLAZGO (Chucapaca project)

At Canteras del Hallazgo (49% owned by Buenaventura), there was a net loss reported in 1Q12 totaling US$5.4 million due to the execution of the project’s exploration program.

Net Income

Buenaventura’s 1Q12 net income was US$207.5 million (US$0.82 per share), an 8% decrease compared to the US$224.8 million (US$0.88 per share) reported in 1Q11. This was mainly due to a 26% decline in operating income.
