Buenaventura Announces

Third Quarter and Nine-month 2024 Results


Lima, Peru, October 30, 2024 – 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 third quarter (3Q24) and nine-month period ended September 30, 2024 (9M24). 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$).

Third Quarter and Nine-Month 2024Highlights:

· 3Q24 EBITDA<br>from direct operations excluding the sale of Chaupiloma Royalty Company was US$ 132.4 million, compared to US$ 53.3 million reported in<br>3Q23. 9M24 EBITDA from direct operations excluding the sale of Chaupiloma Royalty Company reached US$ 333.8 million, compared to US$ 121.9<br>million reported in 9M23.
· 3Q24 net<br>income including the sale of Chaupiloma Royalty Company reached US$ 236.9 million, compared to a US$ 28.0 million net loss for the same<br>period in 2023. 9M24 net income including the sale of Chaupiloma Royalty Company was US$ 369.1 million, compared to US$ 29.6 million in<br>net income for the 9M23.
--- ---
· Buenaventura's<br>cash position reached US$ 457.9 million by quarter’s end, September 30, 2024, while net debt amounted to US$ 224.7 million, resulting<br>in a Leverage Ratio of 0.50x.
--- ---
· Buenaventura's<br>3Q24 consolidated silver production increased by 2.5M Oz, zinc production increased by 96% YoY, and lead production increased by 206%<br>YoY, primarily driven by increased production at Uchucchacua and Yumpag. Gold production increased by 7% YoY due to increased output at<br>Julcani and La Zanja. However, copper production decreased by 9% YoY. In 3Q23, copper production at El Brocal had increased due to higher<br>than estimated copper content mined from the open pit transitional ore.
--- ---
· 100% of<br>the ore stockpiled during 2Q24 due to Buenaventura’s voluntary temporary suspension of El Brocal’s processing plant facilities<br>was processed during the 3Q24. The underground mine reached a record ~12 KTPD average throughput and Uchucchacua reached an average 1,500<br>TPD throughput during 3Q24, which was achieved earlier than had previously been forecast. Yumpag maintained steady 1,000 TPD production<br>during 3Q24.
--- ---
· Buenaventura<br>completed the sale of its Chaupiloma Royalty Company to Franco-Nevada for US$ 210 million during 3Q24, as was announced on August 13,<br>2024.
--- ---
· 3Q24 CAPEX<br>related to San Gabriel was US$ 76.8 million, primarily allocated to the mine’s water dam and to power line construction.
--- ---
· Buenaventura’s<br>credit rating was upgraded by Moody’s to B1 with a positive outlook. Moody’s cited Buenaventura's operational improvements<br>driven by increased production from its El Brocal, Yumpag and Uchucchacua mines as well as efficiency in cost reduction, cash flow generation,<br>and conservative liquidity management as key factors.

CAPEX

3Q24 capital expenditures were US$ 98.0 million, compared to US$ 59.8 million for the same period in 2023. The 3Q24 capex includes US$ 76.8 million for the San Gabriel Project, US$ 8.3 million for the Trapiche Project, and US$ 12.9 million in sustaining capex. 9M24 capital expenditures reached US$ 240.1 million, compared to US$ 145.7 million in 9M23.

Operating Revenues

3Q24 net sales reached US$ 331.1 million, compared to US$ 211.3 million in 3Q23. Increased net sales were primarily driven by a higher volume of silver, lead, and zinc sold related to the resumption of ore processing at the Uchucchacua and Yumpag mines. Additionally, increased sales were also driven by higher prices during the third quarter 2024.

Production and Operating Costs
---

Buenaventura’s 3Q24 equity gold production was 39,690 ounces, compared to 43,449 ounces produced in 3Q23. This decrease was primarily due to decreased production at Orcopampa and Coimolache, which was partially offset by increased production at Julcani and with benefit of re-leaching at La Zanja. 3Q24 silver production was 4,228,250 ounces, compared to 1,472,907 ounces produced in 3Q23. 3Q24 lead production was 4,953 MT, compared to 1,279 MT produced in 3Q23. 3Q24 zinc production was 7,374 MT, compared to 2,663 MT produced in 3Q23. Silver, lead, and zinc production increased during the quarter primarily due to production initiation at Uchucchacua and Yumpag. The Company’s 3Q24 equity copper production was 32,352 MT, compared to 34,075 MT produced in 3Q23, due to decreased production at El Brocal and Cerro Verde.

Coimolache 3Q24 gold production decreased 65% year on year, in line with expectations. During the 3Q24, Buenaventura filed for a leach pad expansion construction permit at Coimolache, which is currently pending with the Ministry of Energy and Mines. Approval is expected by the end of 1Q25, enabling the Company to begin construction in 2Q25 and to resume leaching fresh ore in 3Q25. CAS increased to 2,142 US$/Oz for the 3Q24, from 1,083 US$/Oz in 3Q23 due to previously announced temporary decrease in production until leach pad expansion has been completed.

Uchucchacua’s 3Q24 silver, lead, and zinc production was consistent with expectations for the quarter. Production increased sequentially, to a daily average throughput of 1,500 TPD during 3Q24, aligned with the Company’s targeted 1,500 TPD by year end 2024. Yumpag’s silver production was in line with 3Q24 projections.

3Q24 Silver CAS reached 14.19 US$/Oz below initial estimates, due to the early approval of Yumpag´s operating permit, resulting in higher-grade silver ore than initially estimated for the quarter. Additionally, the increased production of lead and zinc from Uchucchacua also contributed to a reduction in unit costs.

Copper US$/MT 6,054 6,029 0% 6,041 6,290 -4%

El Brocal's 3Q24 copper production decreased by 10% year on year. All ore stockpiled in 2Q24 was processed during the 3Q24, enabling El Brocal to meet its targeted production for the first nine months of 2024. In 3Q23, copper production at El Brocal had increased due to higher than estimated copper content mined from the open pit transitional ore. 3Q24 silver production decreased by 57% year on year compared to the same period of 2023 when the open pit was in operation.

The average mining rate during 3Q24 was 12,000 tons per day, and the average mining rate for the first nine months of the year was 11,000 tons per day, aligned with the Company’s target for full year production to exceed 11,000 tons per day.

3Q24 copper CAS was in line with 3Q23, primarily due to an increase in volume processed during the quarter, resulting from stockpiled ore processed.

Share in Associated Companies

Buenaventura’s share in associated companies was US$ 48.7 million in 3Q24, compared with US$ 46.4 million in 3Q23, comprised of:

Cerro Verde (19.58% owned by Buenaventura)

3Q24 copper production was 111,891 MT, 21,908 MT of which is attributable to Buenaventura; a 3% decrease as compared to 115,441 MT produced in 3Q23, 22,603 MT of which was attributable to Buenaventura.

Cerro Verde reported US$ 253.6 million in 3Q24 net income, compared to US$ 225.5 million in 3Q23 net income. This year on year increase is primarily due to a 3% year on year net sales increase from a higher average realized copper price of US$4.23 per pound, compared to US$3.77 per pound in 3Q23, partially offset by a 7% decrease in copper volume sold. Additionally, 3Q24 results reflect a gain on currency exchange difference as compared to a currency exchange loss in 3Q23. This exchange discrepancy increased 3Q24 results by US$ 29.7 million relative to 3Q23 results. Cerro Verde 3Q24 capital expenditure was US$ 91.1 million.

Coimolache (40.09% owned by Buenaventura)

Coimolache reported a US$ 2.0 million net loss in 3Q24, compared to a US$ 6.6 million net income in 3Q23.


San Gabriel Project

3Q24 capital expenditures were US$ 76.8 million, primarily directed to the water dam and to power line construction.

The commissioning team is in the planning stage, with completion targeted for year-end 2024. Mobilization for the Electrical & Instrumentation, auxiliary buildings, and medium voltage transmission line contractors began during the 3Q24. All structural steel is now on-site and major contracts for the plant and infrastructure have been awarded.

Administrative Expenses
---

3Q24 General and Administrative expenses were US$ 17.0 million; a 3% decrease as compared to US$ 17.5 million in 3Q23. This variation can be attributed primarily to the exclusion of US$ 3.3 million in Administrative expenses related to back office expenses of Contacto, a subsidiary sold by Buenaventura in November 2023. Additionally, a US$ 2.5 million workers' participation provision has been recorded within 3Q24 General and Administrative expenses due to the higher year to date net income reported by the Company. This provision was not included within the Company’s 3Q23 results as Buenaventura recorded a net loss.

*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 Salesand 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.
