Financial Highlights (in millions of US$, except EPS figures):

(*) as of March 31, 2016 Buenaventura had 254,186,867 outstanding shares.

Operating Revenues

During 1Q16, net sales were US$220.6 million, a 4% decrease compared to the US$230.4 million reported in 1Q15. This was mainly explained by the general decline in all metal prices (except for lead), as well as lower gold, lead and zinc volume sold. Silver volume sold increased 13% partially offsetting the decline in sales.

Royalty income decreased 26%, from US$9.1 million in 1Q15 to US$6.7 million reported in 1Q16. This was due to lower revenues at Yanacocha (27% lower QoQ).

Gold production, including associated companies, in 1Q16 was 157,955 ounces, 16% lower than the figure reported for the same period of 2015 (187,468 ounces), explained by a decrease in production from Yanacocha.

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.
