Royalty income decreased 12%; from US$ 5.8 million in 4Q16 to US$ 5.1 million in 4Q17 due to a 12% decrease in revenues at Yanacocha.

Production and Operating Costs
 

In 4Q17, Buenaventura’s consolidated gold production was 114,325 ounces; a 32% quarter on quarter increase as compared to 86,803 gold ounces in 4Q16. This increase is due to new production from Tambomayo and a 9% QoQ increase in production at Orcopampa, which was offset by a 6% QoQ decrease in production at La Zanja mine. Consolidated lead production increased by 31% compared to 4Q16 due to a 92% increase in production at the Uchucchacua mine and a 12% increase at the El Brocal mines.

Buenaventura´s FY17 consolidated gold production increased 14% compared to FY16. Consolidated silver production increased by 8% as compared to FY16, primarily due to an additional 1.8 million ounces in production contributed by Tambomayo and a 55% increase in production at El Brocal. Buenaventura´s consolidated lead production increased 33% in the FY17 compared to FY16. This total increase is due to a 56% increase in production from the Uchucchacua mine and a 58% increase in production from the El Brocal mines.

Yanacocha purchased the IFC´s five percent equity stake in Yanacocha

Yanacocha purchased the International Finance Corporation´s (IFC) five percent equity stake in Yanacocha for $48 million in December 2017. The purchase was made using Yanacocha’s existing cash balance. In 2018, Yanacocha agreed to make a capital reduction, Buenaventura´s stake in Yanacocha therefore increased to 45.95%, from 43.65%.
 
CERRO VERDE

At Cerro Verde (19.58% owned by Buenaventura), 4Q17 copper production was 116,351 MT, 22,782 MT of which is attributable to Buenaventura;  a 12% decrease compared to 132,814 in 4Q16 with 26,005 MT attributable to Buenaventura. FY17 copper production was 481,810 MT; a 4% decrease as compared to 502,495 MT in FY2016.

During 4Q17, Cerro Verde reported a net income of US$ 217.6 million compared to net income of US$ 114.9 million in 4Q16. This increase was primarily due to a US$ 150.0 increase in net sales, primarily related to an increase in average realized copper price to US$ 3.46 per pound in 4Q17, compared to US$ 2.72 in 4Q16.

During 4Q17, Cerro Verde´s concentrator plant averaged 374k metric tons of ore per day, the plant was originally designed for a plant capacity of 360k metric tons per day.

Capital expenditures at Cerro Verde were US$58.1 million in 4Q17 and US$152.8 million in FY17.

In June 2017, Cerro Verde extended the maturity of its Syndicated Loan until 2022, from 2019 under the prior agreement. In December 2017, Cerro Verde repaid US$ 220 million of this loan. The outstanding balance is therefore US$ 1.3 billion as of December 31, 2017.

Copper production guidance at Cerro Verde for 2018 is 460k MT – 500k MT.

COIMOLACHE (Tantahuatay operation)

At Coimolache (40.10% owned by Buenaventura), 4Q17 attributable contribution to net income was US$ 7.7 million, as compared to US$ 6.5 million in 4Q16.

In February 2018, Coimolache signed a contract with Cerro Corona (Gold Fields) to purchase oxide material. Based on this agreement, Coimolache will purchase 6.6 million metric tons of ore at US$ 5.5 per tonne over a three-year period.

De-bottlenecking program
 
 
As previously mentioned, the Company’s De-Bottlenecking Program will continue for the subsequent three years. During 2018 the program will focus on the following:

Opportunity
Tambomayo
Orcopampa
Uchucchacua
El Brocal*
Differential Cut-off
 
Dilution Control
   
Ventilation
 
 
Hoist System
 
 
Backfill System
   
Integrated Mining Contract
 
Process Plant Fine Tuning
   
*At El Brocal this also considers the Esperanza Tunnel Connection and the 13K Copper Project

Projects description

Process Efficiency:
§
Dilution Control : Operating cost reduction through the treatment of higher-value ore; increased production also improves recovery rate .
§
Ventilation : system upgrade to increase productivity and improve exploration.
§
Hoist System : system upgrade to increase productivity.
§
Back-fill System : Reuse tailings to be mixed with cement to support and reinforce the mine. This also reduces costs incurred transporting the tailings to the tailings storage facility and increases the useful life of the storage facility.
§
Process Plant Fine Tuning : Equipment to be purchased to improve process efficiency.
§
Esperanza Tunnel Connection : Marcapunta Norte and Marcapunta Sur have been connected in order to improve operational productivity and reduce cost.

Management Efficiency:

Differential Cut-off : use of a clearly delineated cut-off per area to increase profitability.
Integrated Mining Contracts : Renegotiate contracts with contractors in order to better leverage synergies between Buenaventura’s operating units.

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.
