Buenaventura Announces

Second Quarter and Six-month 2023 Results

Lima, Peru, July 26, 2023 – Compañia de Minas Buenaventura S.A.A. (“Buenaventura” or “the Company”) (NYSE: BVN; Lima Stock Exchange: BUE.LM), Peru’s largest publicly-traded precious metals mining company, today announced results for the second quarter (2Q23) and six-month period ended June 30, 2023 (6M23). All figures have been prepared in accordance with IFRS (International Financial Reporting Standards) on a non-GAAP basis and are stated in U.S. dollars (US$). Buenaventura has provided accumulated six month results to reflect the provisional pricing effect on the first six months of 2023.

Second Quarter and Six-Month 2023 Highlights:

•

2Q23 EBITDA from direct operations was US$ 17.1 million, compared to US$ -12.9 million reported in 2Q22. 6M23 EBITDA from direct operations reached US$ 68.7 million, compared to US$ 74.0 million reported in 6M22. 2022 EBITDA does not include US$ 300 million resulting from the sale of Buenaventura's stake in Yanacocha.

•

2Q23 net loss reached US$ 5.4 million, compared to a US$ 44.6 million net loss for the same period in 2022. 6M23 net income was US$ 67.5 million, compared to US$ 570.1 million net income for the 6M22. The 6M22 result includes a US$ 480 million net income from discontinued operations, primarily due to the reclassification of Buenaventura's interest in Yanacocha.

•

The Company recorded a US$ 9.8 million provisional price adjustment for the accumulated first six months of 2023. This is comprised of US$ -13.7 million in fair value of accounts receivables and US$ +3.9 million in adjustments to prior period liquidations. This compares to a US$ 35.1 million loss for the accumulated first six months of 2022.

•	Buenaventura's 6M23 consolidated copper production increased 23% YoY. Zinc production decreased by 68% YoY, lead decreased by 60% YoY, silver decreased by 28% YoY, and gold decreased by 11% YoY.

•	El Brocal's underground mine production increased to 9,300 tpd during 2Q23, compared to 8,150 tpd in 2Q22. The El Brocal ramp-up remains on target to reach 10,000 tpd by year-end 2023.

•	Buenaventura's cash position reached US$ 202.4 million and net debt decreased to US$ 520.9 million with an average maturity of 2.9 years by quarter’s end, June 30, 2023.

•

2Q23 capital expenditures were US$ 49.7 million, compared to US$ 36.1 million for the same period in 2022. 6M23 capital expenditures reached US$ 85.9 million, compared to US$ 56.0 million in 6M22, and includes US$ 24.0 million related to the San Gabriel Project and US$ 19.2 million related to the Yumpag Project.

•	Buenaventura looks forward to permitting approval of Uchucchacua, Yumpag, El Brocal and Coimolache. The company continues to work with the Peruvian environmental authority (SENACE) on its final review. We expect permits for Uchucchacua and Yumpag to be approved during 3Q23.

•	Cerro Verde paid a total dividend of US$ 250 million on April 28, 2023. Buenaventura received US$ 49.0 million relative to its stake in Cerro Verde. Cerro Verde will pay a second dividend on August 3, 2023, from which Buenaventura will receive an additional US$ 49.0 million.

Production and Operating Costs

Buenaventura’s 2Q23 equity gold production was 35,589 ounces, compared to 39,605 ounces produced in 2Q22, primarily due to decreased production at Tambomayo and Coimolache. 2Q23 silver production decreased by 12% primarily due to Julcani and El Brocal performance. 2Q23 lead and zinc production decreased by 50% and 46%, respectively, due to decreased production at Tambomayo. The Company’s 2Q23 equity copper production was 30,914 MT, compared to 27,900 MT produced in 2Q22.

Gold	US$/Oz	1,175	944	24%	1,172	977	20%

Tambomayo 2Q23 gold production decreased 24% year on year due to lower gold grade and narrower veins mined; in line with the 2023 planned mining sequence. Cost Applicable to Sales (CAS) increased to 1,175 US$/Oz in 2Q23 from 944 US$/Oz in 2Q22. This increase was primarily due to the decreased volume sold in 2Q23.

2Q23 gold production decreased by 57% year on year, in line with the 2023 estimates, as mining and ore stockpiling was suspended in 4Q22. 2Q23 Cost Applicable to Sales (CAS) was 1,938 US$/Oz, an increase from 1,650 US$/Oz gold production in 2Q22 due to suspended mining activity.

Coimolache (40.10% owned by Buenaventura)

Gold	US$/Oz	1,732	867	100%	2,585	1,072	141%

Coimolache 2Q23 gold production decreased by 52% year on year, primarily due to a slower than expected leach pad gold extraction rate with longer than expected percolation time, in line with 2023 estimates. These are expected to increase in the second half of 2023; 2023 guidance therefore remains unchanged. Cost Applicable to Sales (CAS) increased to 1,732 US$/Oz in 2Q23, from 867 US$/Oz in 2Q22 due to decreased volume sold.

Exploration and mine development continues as planned at the Uchucchacua mine. The 2H23 target to resume ore beneficiation at Uchucchacua´s processing plant remains unchanged.

Yumpag 4Q23 targeted production initiation remains unchanged and is subject to the final permitting and approval required to operate, which is expected to be granted in the 2H23 to then begin ore production and haulage to Uchucchacua´s processing plant. Buenaventura will focus on ensuring processing plant operational readiness during 3Q23 to receive ore from Uchucchacua and Yumpag by the end of 2023. Once adequate ore stockpiles have been reached, processing is expected to begin between 4Q23 and 1Q24.

Silver	US$/Oz	21.87	14.71	49%	20.74	14.91	39%

2Q23 silver production decreased 26% year on year primarily due to a negative geology reconciliation with decreased treated ore. 2Q23 Cost Applicable to Sales (CAS) was 21.87 US$/Oz, compared to 14.71 US$/Oz in 2Q22; a 49% year on year increase due to decreased volume sold.

Zinc	US$/MT	1,886	3,938	-52%	1,812	3,008	-40%

El Brocal 2Q23 copper production increased by 25% year on year due to increased ore treated at the Marcapunta underground mine. The El Brocal underground mine processed nearly 9,300 tpd during 2Q23 as part of its mine ramp-up phase and is expected to reach 10,000 tpd by 4Q23.

Silver and zinc production, primarily from the open pit, decreased by 21% and 8% year on year, respectively, as part as the planned transition to copper from polymetallic ore. Mining will continue through 3Q23 until the lead/zinc pit has been fully depleted. Buenaventura has therefore modified its prior mining plan and expects to now process 100% of the El Brocal lead and zinc inventories by year end 2023 with the remaining open pit copper inventories expected in 1Q24.

2Q23 Copper Cost Applicable to Sales (CAS) decreased by 8% year on year due to increased volume sold.

General and Administrative Expenses

2Q23 General and Administrative expenses were US$ 19.0 million; a 15% increase as compared to US$ 16.6 million in 2Q22.

Share in Associated Companies

Buenaventura’s share in associated companies was US$ 7.6 million in 2Q23, compared with US$ 22.3 million in 2Q22, comprised of:

Share in the Result of Associates (in millions of US$)	2Q23	2Q22	Var	6M23	6M22	Var

CERRO VERDE (19.58% owned by Buenaventura)

2Q23 copper production was 116,431 MT, 22,797 MT of which is attributable to Buenaventura; a 6% increase as compared to 109,432 MT produced in 2Q22, 21,427 MT of which was attributable to Buenaventura.

Cerro Verde reported US$ 59.5 million net income in 2Q23, compared to US$ 127.8 million net income in 2Q22 due to an unfavorable result in a tax dispute and an adverse effect of provisional price adjustment.

2Q23 Cerro Verde capital expenditures were US$ 68.8 million.

COIMOLACHE (40.10% owned by Buenaventura)

Coimolache reported a 2Q23 US$ 8.1 million net loss, compared to US$ 1.9 million net loss in 2Q22.

SAN GABRIEL Project

Capital expenditures for 2Q23 and 6M23 was US$ 14.3 million and US$ 24.0 million, respectively, primarily related to earthworks and construction-related water dam excavation. Transmission line permitting continues as planned, four out of five workshops have been completed by the end of 2Q23 and a final public hearing has been scheduled in 3Q23. Power line critical equipment purchases were also completed by the end of 2Q23.

San Gabriel 2023 capital expenditure guidance has been revised to US$ 140 million – US$ 160 million due to slower than expected construction ramp-up. Buenaventura is increasing related earthmoving work to mitigate these delays, also with an additional second earthmoving work front. This revision does not affect project total CAPEX nor targeted production start in the 2H25.

EBITDA Buenaventura + All Associates	87,380	57,805	265,736	591,528

*Cerro Verde’s EBITDA accounts for 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 (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, 2022 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.
