Operating Revenues

During 4Q15, net sales were US$227.5 million, a 14% decrease compared to the US$264.6 million reported in 4Q14. This was mainly explained by the decrease in metal prices as well as lower gold and copper volume sold.

Royalty income decreased 39%, to US$7.2 million in 4Q15 compared to the US$11.9 reported in 4Q14. This was due to lower revenues at Yanacocha (32% lower QoQ).

For 2015, net sales decreased 19%, from US$1,138.9 million in 2014 to US$919.5 million in 2015. Royalty income for 2015 was US$32.4 million (US$36.9 million in 2014).

Production and Operating Costs

In 4Q15, Buenaventura’s gold equity production from direct operations decreased 14%, from 104,166 ounces in 4Q14 to 90,034 ounces in 4Q15 due to the decline in production at Breapampa mine (no production in 4Q15 vs 13,178 gold ounces in 4Q14). Gold production including associated companies in 4Q15 was 182,247 ounces, 26% lower than the reported in the same period 2014, explained by a decrease in production from Yanacocha. Silver equity production from direct operations increased 14%, mainly due to higher production at Uchucchacua mine (13.9 million silver ounces in 2015 vs 12.1 million silver ounces in 2014).

Silver production in 4Q15 increased 21% compared to 4Q14, due to higher ore treated and higher ore grade (Appendix 2). Cost Applicable to Sales (CAS) in 4Q15 decreased 13% compared to 4Q14, mainly explained by lower labor cost due to higher exchange rate, lower consumable costs (explosive materials), reagents costs and more silver ounces sold (4.1 million silver ounces in 4Q15 compared to 3.2 million silver ounces in 4Q14).

Silver production guidance for 2016 is 15.5 million – 16.5 million ounces.

During 4Q15, Copper production decreased 15% compared to 4Q14, due to a lower recovery rate. Moreover, in 4Q15 zinc production increased 85% due to higher ore treated, despite the lower grade.

(*) Since January 2016, the new ownership of El Brocal is 56.29%.

In 4Q15, Zinc CAS increased 9% compared to 4Q14 mainly due to higher selling expenses. Copper CAS in 4Q15 was in line with the CAS reported in 4Q14.

Zinc production guidance for 2016 is 60k – 70k MT, while copper production guidance for 2016 is 35k – 45k MT.

General and Administrative Expenses

General and administrative expenses in 4Q15 were US$25.8million, 9% lower compared to the US$28.4 million in 4Q14 figure. This is mainly due to lower third-party services. For 2015, the expense was US$86.5 million (US$101.1 million in 2014).

Exploration in Non-Operating Areas

Exploration in non-operating areas during 4Q15 was US$5.0 million compared with the US$17.6 million in 3Q14. During the period, Buenaventura’s main exploration efforts were focused on the Tambomayo project (US$3.5 million) and Marcapunta (US$0.6 million).

YANACOCHA

At Yanacocha (43.65% owned by Buenaventura), during 4Q15, gold production was 211,256 ounces, 34% lower than 4Q14 production (322,309 ounces). For 2015, gold production was 917,690 ounces, 5% lower than 969,944 ounces in 2014.

Gold production guidance at Yanacocha for 2016 is 600k – 650k ounces.

In 4Q15, Yanacocha reported net loss of US$547.4 million compared to a net loss of US$380.3 million reported in 4Q14 (Includes deferred income tax of US$510 million). CAS in 4Q15 was US$747/oz, 75% higher than the US$426/oz reported in 4Q14 mainly due to: i) a higher inventory write-down (US$34.7 million in 4Q15 compared to US$11.1 million in 4Q14), and ii) lower volume sold (216,733 gold ounces in 4Q15 vs 327,278 gold ounces in 4Q14).

Capital expenditures at Yanacocha were US$37.3 million in 4Q15, while for 2015 was US$96.2 million.

Yanacocha still has a strong pipeline of growth projects: Quecher Main (prefeasibility), Chaquicocha Sulphides and Yanacocha Verde (scoping) and Maqui Maqui (exploration).

CERRO VERDE

At Cerro Verde (19.58% owned by Buenaventura), during 4Q15 copper production was 95,619 MT (18,722 MT attributable to Buenaventura), a 71% increase compared to 4Q14 (56,001 MT and 10,965 MT attributable to Buenaventura). For 2015, copper production was 246,973 MT (48,357 MT attributable to Buenaventura).

During 4Q15, Cerro Verde reported a net loss of US$13.2 million compared to net profit of US$55.9 million in 4Q14. This was mainly due to a higher depreciation (related to the new concentrate plant) and a higher net loss from currency exchange difference, despite of the 71% increase in volume sold. For 2015, net income was US$33.3 million (compared to US$377.6 million in 2014).

Capital expenditures at Cerro Verde were US$274.1 million in 4Q15, and US$1,595.6 million in 2015.

Cerro Verde’s plant expansion was completed, in-line with schedule and budget (US$4.6 billion). It became the largest concentration facility (360K TPD) in the world and full plant capacity is expected to be reached in 1Q16.

Copper production guidance at Cerro Verde for 2016 is 550k MT – 600k MT.

APPENDIX 5: COST APPLICABLE TO SALES RECONCILIATION

Reconciliation of Costs Applicable to Sales and Cost Applicable to Sales per Unit Sold

Cost applicable to sales consists of cost of sales, excluding depreciation and amortization, plus Selling expenses. Cost applicable to sales per unit sold for each mine consists of cost applicable to sales for a particular metal produced at a given mine divided by the volume of such metal produced at such mine in the specified period. We note that cost applicable to sales is not directly comparable to the cash operating cost figures disclosed in previously furnished earnings releases.

Cost applicable to sales and Cost applicable to sales per unit of mineral sold are not measures of financial performance under IFRS, and may not be comparable to similarly titled measures of other companies. We consider Cost applicable to sales and Cost applicable to sales per unit of mineral sold to be key measures in managing and evaluating our operating performance. These measures are widely reported in the precious metals industry as a benchmark for performance, but do not have standardized meanings. You should not consider Cost applicable to sales or Cost applicable to sales per unit of mineral sold as alternatives to cost of sales determined in accordance with IFRS, as indicators of our operating performance. Cost applicable to sales and Cost applicable to sales per unit of mineral sold are calculated without adjusting for by-product revenue amounts.

The tables below set forth (i) a reconciliation of consolidated Cost of sales, excluding depreciation and amortization to consolidated Cost applicable to sales, (ii) reconciliations of the components of Cost applicable to sales (by mine and mineral) to the corresponding consolidated line items set forth on our consolidated statements of profit or loss for the three and six months ended June 30, 2014 and 2015, and (iii) reconciliations of Cost of sales, excluding depreciation and amortization to Cost applicable to sales for each of our mining units. The amounts set forth in Cost applicable to sales and Cost applicable to sales per unit sold for each mine and mineral indicated in the tables below can be reconciled to the amounts set forth on our consolidated statements of profit or loss for the three and six months ended June 30, 2014 and 2015 by reference to the reconciliations of Cost of sales, excluding depreciation and amortization (by mine and mineral), Selling Expenses (by mine and metal) expenses and Exploration in units in operations (by mine and mineral) to consolidated Cost of sales, excluding depreciation and amortization, consolidated Selling Expenses and consolidated Exploration in units in operations expenses, respectively, set forth below.
