Operating Revenues

Operating Revenues

3Q20 net sales were US$ 223.4 million, in line with US$ 223.6 million reported in 3Q19. Despite the lower volume sold due to the effects of COVID-19, excluding zinc volumes, higher prices (excluding lead) helped to maintain steady net sales figures compared to those reported in 2019.

Royalty income decreased 28% in the 3Q20 to US$ 4.8 million, from US$ 6.6 million in 3Q19. This was due to a 33% decrease in Yanacocha revenues.

Production and Operating Costs

Production and Operating Costs

Buenaventura’s 3Q20 equity gold production was 81,595 ounces, compared to 121,466 ounces produced in 3Q19. This was primarily due to a 26% percent production decrease at Tambomayo, as these operations reached full production capacity in September, and a 44% production decrease at Yanacocha due to continued effects of COVID-19.

Silver equity production decreased by 47% year on year, primarily due to a 71% decrease in production at the Uchucchacua mine, as this mine did not achieve full capacity during the third quarter 2020. Lead equity production decreased by 20% year on year, primarily due to an 84% decrease at the Uchucchacua mine. Zinc equity production increased by 22% year on year, primarily due to a 148% production increase at El Brocal.

3Q20 silver production at Uchucchacua decreased by 71%, primarily due to a reduction in ore treated due to COVID-19 restrictions. Uchucchacua did not achieve full capacity during the third quarter 2020 mainly due to a reduced workforce and shortage of workers required to successfully operate at full capacity.

3Q20 copper production for El Brocal decreased by 28% year on year due to a 32% decrease in ore treated, primarily due to a reduced workforce resulting from COVID-19 restrictions, despite higher ore grades (2%) and a higher recovery rate (3%) during the quarter. 3Q20 zinc production increased by 148% year on year as a result of a 44% increase in ore treated and a 53% increase in grades compared to the same period in 2019.

In 3Q20, Copper Cost Applicable to Sales (CAS) was in-line with that of 3Q19. Zinc CAS increased by 10% year on year for the third quarter 2020, mainly due to increased commercial deductions resulting from less favorable market conditions as compared to 2019.

Operating costs for those months of suspended activities without production due to COVID-19 have been recognized as “Unabsorbed costs due to production stoppage”. In the case of El Brocal, US$ 9.2 million was classified as “Unabsorbed costs” for the 9M20.

3Q20 General and Administrative expenses were US$ 16.8 million; a 4% decrease as compared to US$ 17.4 million in 3Q19. This is due to the Company´s successful cost containment and expense reduction during the quarter, which partially offset the adverse effects of Peru’s State of Emergency.

Exploration in Non-Operating Areas

3Q20 exploration costs in Non-Operating Areas were US$ 1.8 million, compared with US$ 2.4 million in 3Q19. During the period, Buenaventura focused exploration efforts primarily on its Emperatriz project, amounting to US$ 1.2 million in exploration costs during 3Q20.

CERRO VERDE

At Cerro Verde (19.58% owned by Buenaventura), 3Q20 copper production was 98,718 MT, 19,329 MT of which is attributable to Buenaventura; a decrease as compared to 106,567 MT produced in 3Q19, 20,866 MT of which was attributable to Buenaventura.

9M20 copper production was 271,549 MT; 53,169 MT of which was attributable to Buenaventura. 9M19 copper production was 333,163 MT; 65,233 MT of which was attributable to Buenaventura.

Cerro Verde reported a 3Q20 net income of US$ 115.8 million compared to net income of US$ 45.5 million in 3Q19. This is primarily due to a US$ 136.1 million net sales increase primarily attributed to higher average realized copper price (US$ 3.20 per pound in the third quarter of 2020, compared to US$2.47 per pound in the third quarter of 2019). This was partially offset by a higher income tax expense of US$66.3 million.

Capital expenditures at Cerro Verde were US$ 28.5 million in 3Q20.

COIMOLACHE (Tantahuatay operation)

At Coimolache (40.10% owned by Buenaventura), 3Q20 attributable contribution to net income was US$ 3.9 million, as compared to positive US$ 5.4 million in 3Q19.

*Cerro Verde’s EBITDA now considers D&A related to the capitalization of the stripping.

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.

Operations’ Cost applicable to sales does not include operating cost for those months during which Buenaventura’s operations were suspended due to COVID-19, as these have been classified as “Unabsorbed costs due to production stoppage” within the financial statements.

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.
