The decreased in 2Q18 gold production at Orcopampa was primarily due to a 20% QoQ decrease in ore grades. Cost Applicable to Sales (CAS) increased 20% in 2Q18, to 910 US$/Oz, compared to 760 US$/Oz in 2Q17, primarily explained by a decrease in volume sold.

As previously mentioned in our most recent Operating Report released on July 12, 2018, Buenaventura’s management made the decision to temporarily reduce its annual production guidance for Orcopampa in order to centralize the underground operation. Management plans to prioritize Buenaventura’s De-bottlenecking Program over ore mineral extraction.

Gold production guidance for 2018 is 120k – 140k ounces.

2Q18 copper production increased 8% compared to 2Q17, mainly due to a 35% QoQ increase in the amount of ore treated. Zinc production in 2Q18 was in line with that of 2Q17.

In 2Q18, zinc Cost Applicable to Sales (CAS) decreased by 11% compared to 1,838 US$/MT, primarily explained by a decrease in commercial deductions. Copper CAS in 2Q18 increased by 12%, compared to 4,861 US$/MT in 2Q17, mainly due to an increase in exploration expenses: 4,184 DDH meters in 2Q18 vs. 0 in 2Q17.

As discussed within the Company’s most recent Operating Report, the production mix has been modified within El Brocal´s 2018 mining plan. More production will be derived from the polymetallic open mine. The plan is to smoothly and efficiently transition the underground operation from 8k TPD to 13k TPD. El Brocal´s 2018 annual EBITDA budget will not be effected.

Zinc production guidance for 2018 is 45k – 55k MT, while copper production guidance for 2018 is 45k – 55k MT.

Note:
EBITDA (Buenaventura Direct Operations) consists of earnings before net interest, taxes, depreciation and amortization, share in associated companies, net, loss on currency exchange difference, other, net, provision for workers’ profit sharing and provision for long-term officers’ compensation.

EBITDA (including associated companies) consists of EBITDA (Buenaventura Direct Operations), plus (1) Buenaventura’s equity share of EBITDA (Yanacocha) (2) Buenaventura’s equity share of EBITDA (Cerro Verde), plus (3) Buenaventura’s equity share of EBITDA (Coimolache). All EBITDA mentioned were similarly calculated using financial information provided to Buenaventura by the associated companies.

Buenaventura presents EBITDA (Buenaventura Direct Operations) and EBITDA (including affiliates) to provide further information with respect to its operating performance and the operating performance of its equity investees, the affiliates. EBITDA (Buenaventura Direct Operations) and EBITDA (including affiliates) are not a measure of financial performance under IFRS, and may not be comparable to similarly titled measures of other companies. You should not consider EBITDA (Buenaventura Direct Operations) and EBITDA (including affiliates) as alternatives to operating income or net income determined in accordance with IFRS, as an indicator of Buenaventura’s, affiliates operating performance, or as an alternative to cash flows from operating activities, determined in accordance with IFRS, as an indicator of cash flows or as a measure of liquidity.

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 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.
