Buenaventura Announces Second Quarter and Six-Month Period 2013 Results

Compañia 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 results for the second quarter 2013 (2Q13) and six-month (6M13) periods, ended June 30, 2013. All figures have been prepared in accordance with IFRS (International Financial Reporting Standards), are on a non GAAP basis and are stated in U.S. dollars (US$).

Comments from the Chief Executive Officer:

Mr. Roque Benavides, Buenaventura’s Chief Executive Officer, stated:

“During the second quarter, metal prices declines significantly impacted our results, in addition to:

		1.			Lower production in Uchucchacua due to a 10-day strike.
		2.			Lower revenues and quotation period adjustments in El Brocal and Cerro Verde.
		3.			Impairment and write-down adjustments at Yanacocha.

As a consequence, results were lower than expected. Net income in the second quarter was US$19.0 million, 88% lower than the figure reported in 2Q12 (US$153.2 million). EBITDA from Buenaventura’s Direct Operations was US$40.3 million, 65% lower than the figure reported in 2Q12 (US$114.6 million), while EBITDA, including Associates, decreased 47%, from US$351.8 million in 2Q12 to US$187.5 million in 2Q13.

The Company is focusing its activities on value creation by:

		1.			Stopping production in non-profitable operations (Antapite, Poracota and Shila-Paula) and evaluating the performance of the other units.
		2.			Focusing mine exploration activities on high grade and accessible targets.
		3.			Increasing mining operation efficiency / Orcopampa and Uchucchacua.
		4.			Focusing on brownfield explorations to reduce risk.
		5.			Capital expenditures’ control.

Operating Revenues

During 2Q13, net sales were US$273.1 million, an 18% decrease compared to the US$331.8 million reported in 2Q12. This was explained by lower metal prices.

Royalty income decreased 32%, to US$12.7 million in 2Q13 compared to the US$18.7 million reported in 2Q12. This was due to lower revenues at Yanacocha.

Net sales for the first six months of 2013 were US$614.0 million, 11% lower than in the first six months of 2012, while royalty income was US$26.5 million in 6M13, a 28% decrease compared to the US$36.8 million reported in 6M12.

Production and Operating Costs

Buenaventura’s equity production¹ in 2Q13 was 98,210 ounces of gold, 8% lower than the 107,168 ounces reported in 2Q12, mainly due to a production decline at Orcopampa and Poracota. This was offset by a production increase at La Zanja and Breapampa. Silver production, including associated companies, during 2Q13 was 4,420,340 million ounces, a 2% decrease when compared to the figure reported in 2Q12 (4,509,259 million oz.).

Equity production¹ in 6M13 was 203,673 ounces of gold and 9.1 million ounces of silver. This represented a 9% decrease in gold production (107,168 oz. in 2012), and a 7% increase in silver production compared to 6M12 (8.5 million oz.).

Orcopampa’s (100% owned by Buenaventura) total gold production in 2Q13 was 54,988 ounces, 9% lower than the 60,745 ounces reported in 2Q12. Production from the Chipmo mine during 2Q13 was 50,196 ounces, 12% lower compared to the 56,762 ounces reported in 2Q12, due to lower ore grade (see Appendix 2). The old tailings treatment produced 4,791 ounces of gold (compared to 3,984 oz. in 2Q12). Total gold production in 6M13 was 8,903 ounces, an 18% decrease when compared to 6M12 (10,891 oz.).

Cash operating cost in 2Q13 was US$792/oz., 46% higher when compared to 2Q12 (US$542/oz.). This was mainly explained by the lower gold production and higher contractor costs that resulted from an increase in drilling works and drifting to reach Pucay area.

At Uchucchacua (100% owned by Buenaventura), total silver production in 2Q13 was 2.7 million ounces, in-line with 2Q12 production. The lower ore treated, due to a 10-day strike in April, was offset by an increase in the recovery rate, from 72% (2Q12) to 83% (2Q13)(see Appendix 2). Zinc production in 2Q13 was 1,938 MT, 5% lower than the figure reported in 2Q12 (2,036 MT), while lead production increased 4% (1,966 MT in 2Q13 vs. 1,891 MT in 2Q12). During 2013, silver production was 5.7 million ounces; zinc production was 3,936 MT, while lead production was 4,171 MT vs. 5.5 million ounces, 4,247 MT and 3,981 MT, respectively, in 6M12.

Despite the 10-day strike impact, cash operating cost in 2Q13 was US$16.20/oz., 3% lower than the figure reported in 2Q12 (US$16.65/oz.) due to:

		1.			A better recovery rate
		2.			Lower reagent consumption (cyanide and lime) due to plant optimization
		3.			Lower treatment charges due to lower prices

¹ Production from Direct Operations includes 100% of Buenaventura’s operating units, 100% of CEDIMIN, 53.06% of La Zanja, 40.10% of Tantahuatay and 53.76% of El Brocal.

At Julcani (100% owned by Buenaventura), total production in 2Q13 was 548,890 ounces of silver, 9% lower compared to 2Q12 (602,764 ounces) due to lower ore grade, a 20-day stoppage that was offset by the increase in plant capacity (from 400 TPD to 500 TPD). During 6M13, silver production was 1.16 million ounces, 6% lower than the 1.23 million figure reported in 6M12.

Silver cash operating cost in 2Q13 was US$15.64/oz., 27% higher than 2Q12 (US$12.33/oz.), mainly explained by higher expenses for contractors due to productivity bonuses that were paid in April and unexpected expenses related to the stoppage.

Breapampa’s (100% owned by Buenaventura) total production in 2Q13 was 19,342 ounces of gold with a cash cost of US$410/oz.

La Zanja’s (53.06% owned by Buenaventura) total production in 2Q13 was 37,045 ounces of gold, a 34% increase when compared to 2Q12 (27,687 oz.) due to an increase in the ore grade (0.73 g/MT in 2Q13 vs 0.55 g/MT in 2Q12). 6M13 gold production was 68,251 ounces, 26% higher than in 6M12 (54,016 oz.), but in-line with La Zanja’s mining plan.

Cash operating cost in 2Q13 was US$579/oz., 5% lower than 2Q12 (US$607/oz.) due to a better stripping ratio (0.22 in 2Q13 vs 0.67 in 2Q12).

Tantahuatay’s (40.10% owned by Buenaventura) total production in 2Q13 was 35,382 ounces of gold (14,188 oz. attributable to Buenaventura) 10% lower than the figure reported in 2Q12 (39,129 oz. and 15,691 oz. attributable to Buenaventura). During 6M13, gold production was 69,689 ounces (27,945 oz. attributable to Buenaventura).

Cash operating cost in 2Q13 was US$447/oz., 16% higher than 2Q12 (US$385/oz.) due to the lower tonnage treated, to keep within the limits of the permits, and silver by-product contribution.

At El Brocal (53.76% owned by Buenaventura), copper production was 5,050 MT vs 496 MT reported in 2Q12. For 6M13, copper production increased 57% (9,586 MT in 2Q13 versus 6,110 MT in 2Q12). Copper cash cost was US$6,524/MT, in-line with the figure reported in 2Q12 (US$6,500/MT).

Silver production decreased 69% from 1.3 ounces in 2Q12 to 0.4 ounces in 2Q13 due to lower tonnage treated and ore grade. For 6M13, silver production decreased 49% from 1.7 million oz. (in 2Q12) to 0.9 million oz. (in 2Q13).

During 2Q12, total zinc production was 10,832 MT, a 23% decrease when compared to the 14,044 MT reported in 2Q13. However, in 6M13, copper production increased 57% (9,586 MT in 2Q13 versus 6,110 MT in 2Q12). Zinc cash cost was US$1,073/MT, 29% lower than the figure reported in 2Q12 (US$1,511/MT).

General and Administrative Expenses

General and administrative expenses in 2Q13 were US$23.6 million, 6% lower than the figure reported in 2Q12 (US$25.0 million). This expense included a US$5.7 million charge related to the merger with our subsidiary CEDIMIN. For the six-month period of 2013, general and administrative expenses were US$39.6 million versus US$54.8 million in the same period of 2012, representing a decline of 28%.

Exploration in Non-Operating Areas

Exploration in non-operating areas during 2Q13 reached a positive US$4.1 million, compared to US$26.4 million reported in 2Q12. During the period, Buenaventura’s main exploration efforts were focused on the following projects: Chanca (US$1.3 million), Surichata (US$0.8 million) and La Zanja underground (US$0.8 million). For 6M13, exploration in non-operating areas were US$17.7 million versus US$45.8 million in 6M12, representing a decrease of 61%.

Operating Income

Operating income in 2Q13 was a negative US$4.3 million, compared to the US$81.2 million reported in 2Q12. This decrease was mainly due to 18% lower revenues and 30% higher operating costs.

For 6M13, operating income was US$55.1 million, versus US$210.9 million in 6M12, representing a decrease of 74%.

Share in Associated Companies

During 2Q13, Buenaventura’s share in associated companies were US$48.8 million, 60% lower than the US$122.2 million reported in 2Q12. Yanacocha’s contribution towards these results decreased 73%, from US$86.6 million in 2Q12 to US$23.8 million in 2Q13; Cerro Verde’s contribution decreased 39%, from US$34.0 million in 2Q12 to US$20.8 million in 2Q13. Coimolache’s (Tantahuatay mine) contribution decreased 79% (US$2.1 million in 2Q13 vs. US$9.6 million in 2Q12).

During 6M13, Buenaventura’s share in associated companies was US$133.0 million, 48% lower than the figure reported in 2012 (US$258.0 million).

YANACOCHA

At Yanacocha (43.65% owned by Buenaventura), 2Q13 gold production was 291,428 ounces of gold, 25% lower than 2Q12 production (389,979 oz.), but higher than previously mentioned in the guidance. Accumulated gold production in 2013 was 576,903 ounces, 24% lower than 2013 (756,407 oz.).

Costs applicable to sales (CAS) at Yanacocha in 2Q13 were US$676/oz., 39% higher than the figure reported in 2Q12 (US$488/oz.) explained by a US$163/oz. inventories write-down from La Quinua, Yanacocha and Maqui Maqui pads, due to the fall in gold prices. As a result of this US$48.5 million adjustment, net income decreased 73% (US$54.5 million in 2Q13 vs. US$198.3 million in 2Q12). Accumulated net income in 2013 was US$171.3 million, 57% lower than 2012 (US$400.3 million).

During 2Q13, EBITDA totaled US$177.2 million, a 53% decrease compared to 2Q12 (US$375.3 million). Accumulated EBITDA in 2013 was US$438.1 million, 41% lower than 2013 (US$739.2 million).

Capital expenditures at Yanacocha were US$119.6 million in 2Q13 (US$332.9 million in 2Q12) and US$253.3 million in 6M13 (US$560.3 million in 6M12).

CERRO VERDE

At Cerro Verde (19.58% owned by Buenaventura), 2Q13 copper production was 61,813 MT (12,103 MT attributable to Buenaventura), a 28% increase compared to 2Q12 (48,144 MT and 9,427 MT attributable to Buenaventura). Accumulated total copper production in 2013 was 117,026 MT (22,914 MT attributable to Buenaventura), 11% lower than 131,625 MT in 2013 (25,772 MT attributable to Buenaventura).

During 2Q13, Cerro Verde reported net income of US$106.3 million, a 39% decrease compared to US$173.9 million in 2Q12. This was mainly due to a 19% decrease in sales revenues (US$389.6 million in 2Q13 versus US$482.2 million in 2Q12) explained by the lower copper prices. Accumulated net income in 2013 was US$245.1 million, 40% lower than US$406.1 million in 2013.

Capital expenditures at Cerro Verde in 2Q13 totaled US$240.3 million and US$410.3 in 2013.

COIMOLACHE (Tantahuatay operation)

At Coimolache (40.10% owned by Buenaventura), attributable contribution was US$2.1 million (US$9.6 million in 2Q12). During 6M13, attributable contribution was US$10.2 million (US$17.9 million in 6M12).

CANTERAS DEL HALLAZGO (Chucapaca project)

Studies are currently being conducted towards evaluating a potential underground mining scenario, a review of capital expenditures, along with the construction of a decline towards the higher grade area oriented to the high grade resource enhancement.

Net Income

Buenaventura’s 2Q13 net income was US$19.0 million (US$0.07 per share), an 88% decrease compared to the US$153.2 million (US$0.60 per share) reported in 2Q12. Accumulated net income in 6M13 was US$121.6 million (US$0.48 per share), 66% lower compared to 6M12 (US$361.3 million).
