2Q22 gold production at Tambomayo decreased 20% year on year, primarily due to a 28% decrease in the gold grade despite increased amounts of ore treated. Cost Applicable to Sales (CAS) increased to 944 US$/Oz in 2Q22, from 873 US$/Oz in 2Q21. This primarily due to a 48% year on year increase in commercial deductions, as the Company sold more lead and zinc concentrates and less gold and silver during the second quarter of 2022.

La Zanja’s mining plan has been updated to reflect an inflation based OpEx increase in Phase 5 of the Pampa Verde pit. Mining operations will therefore only be extended through October 2022 when Phase 4 mining will be completed. Operations will be limited to pad leaching during November 2022 while Buenaventura continues exploration related to the underground Cu/Au-sulphide project.

El Brocal 2Q22 copper production was in line with 2Q21 production. Zinc and silver production decreased by 52% and 50%, respectively, year on year as part as the planned transition from polymetallic to copper ore as well as due to the need to alter El Brocal’s mine plan as a result of the landslide which occurred within the mine’s open pit on March 19, 2022.

2Q22 Copper Cost Applicable to Sales (CAS) increased by 16% year on year, mainly due to a 10% year on year increase in cost of sales driven by ramp-up from 7,500 to 8,500tpd during 2022 as well as inflationary pressures in diesel, reagents and consumables. 2Q22 Zinc CAS increased by 168% year on year due to a 52% decrease in zinc production.


General and Administrative Expenses

2Q22 General and Administrative expenses were US$ 16.6 million; an 3% increase as compared to US$ 16.1 million in 2Q21.


Exploration in Non-Operating Areas

2Q22 exploration costs in Non-Operating Areas were US$ 4.8 million, compared with US$ 2.0 million in 2Q21. The increase in exploration during the quarter is in line with Buenaventura’s strategy to focus on extending LOM.

Cerro Verde reported 2Q22 net income of US$ 127.8 million, compared to net income of US$ 240.3 million in 2Q21. This is primarily due to:

ii.
An increase in costs due to an inflationary increase materials and supplies
iii.
Increased selling expenses associated with an increase in ocean freight coupled with higher sales volumes. This decrease was partially offset by a year-on-year income tax decrease.

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 (Cerro Verde), plus (2) 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.

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 twelve months ended December 31, 2020 and 2021 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 twelve months ended December 31, 2021 and 2022 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.
