Lima, Peru, February 24, 2022 – 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 fourth quarter (4Q21) and full year (FY21) ended December 31, 2021.  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$).

--- ---
4Q21 net income reached US$ 163.0 million, compared to a US$ 7.8 million net loss for the same period in 2020 excluding discontinued operations. Increased net income year on year is due to improved Cerro<br> Verde results which were partially offset by one-off provision related to an early termination of contracts at Uchucchacua when operations were suspended. FY21 net income was US$ 124.8 million, compared to a US$ 83.5 million net loss in<br> the FY20 excluding discontinued operations.
--- ---
4Q21 exploration at operating units increased to US$ 15.5 million, from US$ 12.0 million in 4Q20; aligned with the Company’s strategy to focus primarily on exploration. FY21 exploration at operating units<br> increased to US$ 56.4 million, from US$ 28.0 million in FY20.

2022 Highlights

Buenaventura’s Board of Directors has proposed a dividend payment in the amount of US$ 0.073 per share/ADS, aligned with the Company’s commitment to its shareholders.
The Company’s portfolio of Greenfield projects progressed well during the fourth quarter 2021. The San Gabriel (Au) project concluded its ‘Pre-Consultation’ processes with the Corire and Oyo-Oyo<br> communities, both of which would be most closely affected by the project. Construction permits are expected by 2Q22 followed by the full funding decision.
--- ---
Yumpag (Ag) project, which will add close to 30 MOz-Ag to the Uchucchacua LOM, progressed according to plan including EIA which is currently under review by the authorities. In the meantime, detailed<br> engineering is progressing related to the construction permit application process. This will enable Yumpaq to increase silver production in early 2024, adding to Uchucchacua production once operations have resumed.
--- ---
Buenaventura announced on February 8, 2022 that it sold its total stake in Yanacocha for US$ 300 million with contingent payments of up to US$ 100 million tied to future increases in metal prices.<br> Additionally, Newmont transferred its ownership interest in the La Zanja joint venture to Buenaventura in exchange for royalties on any future production and contributed an additional $45 million to cover future closure costs.
--- ---
The net proceeds of the Yanacocha sale, combined with the dividends received from Cerro Verde during 4Q21, enable Buenaventura to fully pre-pay US$ 275 million of its syndicated loan, representing 100% of<br> the outstanding debt, while also partially funding the San Gabriel project. This decision is aligned with Buenaventura´s commitment to deleveraging the company and improving its balance sheet.
--- ---
Buenaventura finished its ESG Materiality Assessment in 2021, which serves as a roadmap for its sustainability strategy. In 2022, Buenaventura will focus on measuring KPIs such as carbon emissions, water<br> consumption and management, and human rights due diligence, among others.
--- ---

2022 CAPEX Guidance

The company expects a total CAPEX between US$ 190 – 210 million during 2022 including US$ 90 – 100 million in sustaining capex and US$ 100 – 110 million in growth capex, primarily related to investments in<br> San Gabriel.
Operating Revenues
---

4Q21 net sales were US$ 249.7 million, as compared to US$ 231.5 million reported in 4Q20; a slight year-on-year increase driven by higher base metal prices during the quarter with an increase in copper volume sold.

Gold US$/Oz 1,023 1,011 1% 950 941 1%

4Q21 gold production at Tambomayo increased 17% year on year, primarily due to increased metallurgical recovery which was partially offset by decreased gold recovery due a re-scheduled high-grade sill pillar. This sill pillar will be mined during 1Q and 2Q of 2022.

4Q21 Cost Applicable to Sales (CAS) increased to 1,023 US$/Oz, from 1,011 US$/Oz in 4Q20, primarily due to a 29% year on year increase in commercial deductions, as the Company sold more doré bars during the fourth quarter 2020. COVID-19 related expenses also increased by US$ 0.8 M, year on year.

Gold production guidance for 2022 is 45k – 50k ounces and silver production guidance is 1.8M – 2.4M ounces.

Increased 4Q21 gold production at Orcopampa was primarily due to a 157% year on year increase in ore volume treated due to earlier than expected production from the Pucara Ramal 4, 5 and 6 vein system. Cost Applicable to Sales (CAS) decreased to 1,023 US$/Oz in 4Q21, compared to 1,318 US$/Oz in 4Q20 due to a more stable operation despite a 55% increase in exploration expenses. COVID-19 related expenses also increased by US$ 0.7 M year on year.

Gold production guidance for 2022 is 57k – 65k ounces

Contractor de-mobilization was completed in 4Q21. Tunneling resumed in December 2021 with Buenaventura personnel and resources as well as diamond drilling completed by a contractor. Both activities focused on exploration. The total amount of meters in tunneling and diamond drilling will increase during 2022 as part of the strategy to temporarily suspend operations and explore and reschedule mine development. Operations are expected to resume in the near future, with more stable and efficient KPIs.

El Brocal 4Q21 copper production increased by 11% year on year. Tajo Norte 4Q21 zinc production decreased by 38% year on year as part of the anticipated transition from polymetallic to copper ore in the open pit mining sequence.

4Q21 Copper Cost Applicable to Sales (CAS) increased by 38% year on year while zinc CAS increased by 9% year on year. These increases are primarily due to: (1) a US$ 4.8 M year on year increase in COVID-19 related expenses and (2) the stripping ratio increase by 15 times, as compared to seven times for the same period in 2020.

Zinc production guidance for 2022 is 18k – 22k metric tonnes, lead production guidance for 2022 is 7k – 10k metric tonnes and copper production guidance for 2022 is 40k – 45k metric tonnes.

General and Administrative Expenses

4Q21 General and Administrative expenses were US$ 18.9 million; a 9% increase as compared to US$ 17.3 million in 4Q20.

Exploration in Non-Operating Areas

4Q21 Non-Operating Area exploration costs were US$ 4.0 million, compared with US$ 3.2 million in 4Q20. During the fourth quarter 2021, Buenaventura focused exploration primarily on its Emperatriz project, resulting in US$ 2.2 million in exploration costs during 4Q21. Increased exploration during the quarter is aligned with Buenaventura’s Strategy to focus on extending LOM.

Net gain (loss) for currency exchange difference
---

4Q21 currency exchange related net loss was US$ 22.8 million, compared with a net loss of US$ 0.2 million in 4Q20 due to a year on year weakening of the PEN relative to the US dollar (3.624 PEN/USD in 2020 vs 3.998 PEN/USD in 2021). SUNAT’s claim is registered in Peruvian Soles as part of Buenaventura’s ‘accounts receivables’, therefore, a higher exchange rate decreases the total amount when converted to US dollars.

Share in Associated Companies

During 4Q21, Buenaventura’s share in associated companies increased to US$ 73.8 million, compared to US$ 37.6 million reported in 4Q20, comprised of:

CERRO VERDE (19.58% owned by Buenaventura)

4Q21 copper production was 108,074 MT, 21,161 MT of which is attributable to Buenaventura; an increase as compared to 100,442 MT produced in 4Q20; 19,666 MT of which was attributable to Buenaventura.

Cerro Verde reported 4Q21 net income of US$ 381.7 million, compared to net income of US$ 150.6 million in 4Q20. This is primarily due to a 34% year on year net sales increase, mainly due to a higher average realized copper price of US$ 4.76 per pound in the fourth quarter of 2021, compared to US$ 3.83 per pound in the fourth quarter of 2020. This increase was partially offset by a year-on-year income tax increase and on workers participation.

4Q21 capital expenditures at Cerro Verde were US$ 54.6 million.

COIMOLACHE (40.10% owned by Buenaventura)

4Q21 attributable contribution to net loss was US$ 0.5 million, as compared to US$ 8.6 million attributable contribution to net income in 4Q20.

Loss from discontinued operations

In December 2021, Buenaventura's management reclassified its investment held with Yanacocha as available for sale, which at December 31, 2021 was registered as a US$ 264.8 million liability in the Statement of Financial Position.

Under IFRS 5 "Non-current assets held for sale and discontinued operations", the Group's management determined that its operation in Yanacocha qualified to be recognized as a discontinued operation and therefore reclassified the effects recorded in the Income Statement for the years 2020 and 2019 under the account "Net loss from discontinued operations attributable to the parent company".

On February 7, 2022, the Company entered into definitive agreements with Newmont Corporation ("Newmont") to sell its entire interest in Yanacocha, see details in note.

APPENDIX 5: 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, 2020 and 2021 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.
