Operating Revenues

During 2Q16, net sales were US$ 279.4 million, an 18% increase compared to the US$ 236.6 million reported in 2Q15. This was mainly explained by an increase in gold and silver prices as well additional volume sold of all metals.

The higher revenues from our operations partially offset a royalty income decrease of 21%, to US$ 5.9 million in 2Q16 compared to the US$ 7.4 reported in 2Q15. This was due to lower revenues at Yanacocha (19% lower QoQ).

For 6M16, net sales increased 7%, from US$ 466.9 million in 6M15 to US$ 500.1 million in 6M16. Royalty income for 6M16 was US$ 12.5 million (US$ 16.5 million in 2015).

Production and Operating Costs

In 2Q16, Buenaventura’s gold equity production from direct operations was in-line compared to the figure reported in 2Q15 (84,997 gold ounces in 2Q16 vs 86,334 gold ounces in 2Q15). Gold production including associated companies in 2Q16 was 152,884 ounces, 15% lower than the amount reported in the same period 2015. This is explained by a decrease in production from Yanacocha. Silver equity production from direct operations increased 35%, mainly due to higher production at the Uchucchacua mine and the Mallay mine (5.7 million silver ounces in 2Q16 vs 4.2 million silver ounces in 2Q15).

Gold production at Orcopampa decreased 8% in 2Q16 (compared to 2Q15) mainly due to lower ore grade (Appendix 2). Cost Applicable to Sales (CAS) in 2Q16 was US$ 704/oz of gold, in line with the Cost Applicable to Sales (CAS) reported in 2Q15.

Gold production guidance for 2016 is 190k – 200k ounces.

Silver production in 2Q16 increased 57% compared to 2Q15, due to higher volumes of ore treated (29-day stoppage in May 2015) and higher ore grade (Appendix 2). Cost Applicable to Sales (CAS) in 2Q16 decreased 29% compared to 2Q15, primarily due to lower labor expenses resulting from a reduced headcount and lower reagent cost and consumption.

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

Silver production in 2Q16 increased 45% compared to 2Q15, due to increased amounts of ore treated (Appendix 2). Cost Applicable to Sales (CAS) in 2Q16 was 7% lower compared to 2Q15 due to more volume sold, lower reagent cost and consumption.

Silver production guidance for 2016 is 1.5 million – 1.9 million ounces.

Silver production in 2Q16 increased 7% compared to 2Q15 production, mainly due to a higher ore grade (Appendix 2). Cost Applicable to Sales (CAS) in 2Q16 was 7% lower than 2Q15, primarily due to fewer meters drifted and lower reagents cost and consumption, despite lower volume sold.

Silver production guidance for 2016 is 3.0 million – 3.4 million ounces.

Gold production in 2Q16 decreased 5% compared to 2Q15. CAS in 2Q16 decreased 35% compared to 2Q15, primarily due to i) lower headcount generated by new synergies with Tantahuatay mine, ii) lower reagent prices and consumption, and iii) lower contractor expenses due to better prices.

Gold production guidance for 2016 is 130k – 140k ounces.

Gold production in 2Q16 increased 14% compared to the figure reported in 2Q15. CAS in 2Q16 decreased 6% compared to 2Q15 mainly due to lower reagent consumption and prices.

Gold production guidance for 2016 is 145k – 155k ounces.

During 2Q16, Copper production increased 22% compared to 2Q15, due to a higher ore volume treated and ore grade. Moreover, in 2Q16 zinc production increased 18% due to higher ore treated and recovery rate.

(*) Since May 2016, the new ownership of El Brocal is 59.26%.

In 2Q16, Zinc CAS was in line with the Cost Applicable to Sales (CAS) reported in 2Q15. Copper CAS in 2Q16 decreased 9% compared to 2Q15 mainly due lower commercial deductions per ton due the renegotiation of the commercial contracts.

APPENDIX 4: 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.
