Second Quarter 2020 Highlights:

2Q20 results were adversely impacted by the State of Emergency and related mandated lockdown instituted by the Peruvian Government in order to contain the spread of the Coronavirus (COVID-19).

As of the date of this press release, the Company expects to reach full capacity at all operations by the end of August.
2Q20 EBITDA from direct operations was US$ 26.5 million, compared to US$ 47.1 million reported in 2Q19.
--- ---
June 2020 EBITDA from direct operations was US$33.3 million, an initial indication of post-State of Emergency restriction recovery.

2Q20 Adjusted EBITDA including associated companies reached US$ 86.1 million, compared to US$ 137.3 million in 2Q19.
--- ---
2Q20 capital expenditures were US$ 11.6 million, compared to US$ 28.8 million for the same period in 2019.
--- ---
2Q20 net loss was US$ 25.1 million, compared to a net income of US$ 9.7 million for the same period in 2019. US$2.9 million of the above net loss was due to additional expenses related to the effect of COVID-19<br> on a consolidated basis.

2Q20 net sales were US$ 94.2 million, compared to US$ 210.8 million reported in 2Q19. This was primarily due to a 46% year on year decrease in gold volumes sold, a 73% year on year decrease in silver volumes sold, 75% year on year decrease in lead volumes sold, a 72% year on year decrease in zinc volumes sold and a 70% year on year decrease in copper volumes sold primarily due to the impact of the State of Emergency declared by the Peruvian government.

Royalty income decreased 34% in the 2Q20 to US$ 3.6 million, from US$ 5.4 million in 2Q19. This was due to a 31% decrease in revenues at Yanacocha.

Production and Operating Costs
---

Buenaventura’s 2Q20 equity gold production was 62,029 ounces, compared to 115,245 reported in 2Q19, primarily due to a 30% percent production decrease at Tambomayo and a 51% production decrease at Yanacocha due to the impact of the Peruvian government’s State of Emergency.

Silver equity production decreased by 64% year on year, primarily due to a 68% decrease in production at the Uchucchacua mine. Lead equity production decreased by 75% year on year, primarily due to a 74% production decrease at El Brocal and 87% decrease at the Uchucchacua mine. Zinc equity production decreased by 75% year on year, primarily due to a 65% production decrease at El Brocal and 92% decrease at the Uchucchacua mine. The above is directly related to the impact of the Peruvian government’s State of Emergency.

2Q20 year on year gold production at Tambomayo decreased 30% mainly due to a reduction in ore treated due to State of Emergency restrictions as well as low gold grade inventories treated in April. Cost Applicable to Sales (CAS) increased to 736 US$/Oz in 2Q20, compared to 558 US$/Oz in 2Q19, primarily due to at 40% decrease in volume sold.

Tambomayo ended June 2020 with a 9,000 ounce increase in gold inventory, which is more than usual for this time period.

Cerro Verde reported a 2Q20 net income of US$ 68.7 million compared to net income of US$ 53.3 million in 2Q19. This is primarily due to a US$163.5 million decrease in cost of sales as a result of lower supplies, depreciation, labor and energy costs related to the State of Emergency restrictions. This was mainly offset by a US$115 million decrease in volume sold.

Capital expenditures at Cerro Verde were US$ 36.8 million in 2Q20.

COIMOLACHE (Tantahuatay operation)

*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.

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.
