Production and Operating Costs

In 4Q16, Buenaventura’s gold equity production from direct operations was 68,268, 4% lower compared to the figure reported in 4Q15 (70,910 gold ounces). Gold production including associated companies in 4Q16 was 159,212 ounces, 13% lower than the amount reported in the same period 2015. This decline is explained by a decrease in production from Yanacocha.

Buenaventura´s gold equity production from direct operations in FY16 was in line compared to the figure reported in FY15. Silver equity production from direct operations in FY16 was 11% higher compared to FY15, this was mainly due to higher production coming from the Uchuchacua (16% YoY) and Mallay (27% YoY) mines. Buenaventura´s Zinc equity production increased 18% in FY16 compared to FY15. This increment is explained by higher production from the Uchuchacua mine (27% YoY), Mallay mine (14% YoY) and El Brocal (8% YoY). Buenaventura´s copper production increased 65% in FY15 compared to FY15 due to higher production from El Brocal (53% YoY).

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 nine months ended September 30, 2015 and 2016, 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 nine months ended September 30, 2015 and 2016 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.
