Operating Revenues

3Q21 net sales were US$ 216.9 million, as compared to US$ 223.4 million reported in 3Q20; a slight year-on-year decrease driven by lower gold and silver prices during the quarter and a decrease in gold, lead and zinc volume sold.

3Q21 royalty income decreased 28% to US$ 3.4 million, from US$ 4.8 million in 3Q20. This was due to a 26% decrease in Yanacocha revenues.

Cost Applicable to Sales
		3Q21	3Q20	Var %	9M21	9M20	Var %
Gold	US$/Oz	973	821	18%	922	910	1%

3Q21 gold production at Tambomayo increased 11% year on year, primarily due to a 36% increase in ore milled. However, gold grade decreased by 26% during the quarter due to the change in ore stope sequencing. A gradual gold grade recovery is expected during the fourth quarter of 2021.

Cost Applicable to Sales (CAS) increased to 973 US$/Oz in 3Q21, from 821 US$/Oz in 3Q20, primarily due to a year on year increase in concentrates sold with a correlating 70% increase in commercial deductions, as the Company sold more doré bars during the third quarter 2020. Third quarter 2021 CAS also increased during the third quarter 2021 due to mine development ground support which was more significant than expected. COVID-19 related expenses also increased by US$ 0.3 M, year on year.

Orcopampa (100% owned by Buenaventura)

Production
		3Q21	3Q20	Var %	9M21	9M20	Var %

Gold	US$/Oz	1,147	754	52%	1,476	820	80%

Increased 3Q21 gold production at Orcopampa was primarily due to a 176% year on year increase in ore volume treated. The increase in ore treated resulted from early production from the Pucara Ramal 4, 5 and 6 vein system and low grade stockpiles near the processing plant. Cost Applicable to Sales (CAS) increased to 1,147 US$/Oz in 3Q21, compared to 754 US$/Oz in 3Q20, primarily due to a 166% increase in exploration expenses. COVID-19 related expenses also increased by US$ 0.9 M year on year.

Third Quarter 2021 Results

Page 5 of 25

3Q21 gold production increased by 17% year on year due to increased volume treated with a positive gold grade reconciliation of the Pampa Verde open pit Phase 4. 3Q21 Cost Applicable to Sales (CAS) was 1,763 US$/Oz; a 4% increase compared to 1,689 US$/Oz in 3Q20 primarily due to an increase in exploration costs, to reach US$ 139k for the third quarter 2021. COVID-19 related expenses also increased by US$ 0.6 M year on year.

		3Q21	3Q20	Var %	9M21	9M20	Var %
Gold	US$/Oz	973	800	22%	1,213	884	37%

3Q21 gold production at Coimolache increased by 12% year on year, primarily due to a 5% increase in gold grade driven by a positive reconciliation at the Cienaga and Mirador open pits. The recovery rate also increased by 39% despite a decrease in ore treated. 3Q21 Cost Applicable to Sales (CAS) increased 16% to 973 US$/Oz; compared to 800 US$/Oz in 3Q20, mainly due to a significant US$ 1.7 M increase in exploration expenses. COVID-19 related expenses also increased by US$ 0.3 M year on year.

Uchucchacua (100% owned by Buenaventura)

Production
		3Q21	3Q20	Var %	9M21	9M20	Var %
Silver	Oz	1,220,393	790,313	54%	3,732,391	3,725,784	0%

Silver	US$/Oz	25.98	27.65	-6%	27.84	19.46	43%

3Q21 silver production at Uchucchacua increased by 54%, primarily due to an increase in ore treated despite the suspension of operations subsequent to the local community strike initiated on September 13, 2021. Production was also adversely affected by a reduced workforce during 2021 due to continued COVID-19 related personnel restrictions. 3Q21 Cost Applicable to Sales (CAS) decreased by 6% year on year, mainly due to increased volume sold. COVID-19 related expenses also increased by US$ 1.2 M year on year.

Production suspension at Uchucchacua enables the Company to achieve the most significant cash preservation while de-risking future negative free cash flow generation through the following:

●	Workforce optimization in order to reduce fixed costs (estimated between US$ 2.0M and US$ 5.0M per year).

●	Decreased COVID-19-related expenses (estimated between US$ 12.0M and US$ 15.0M in 2022).

●	Re-evaluation of existing contracts to renegotiate, reconcile and streamline the Company’s contractor base (estimated between US$7.0M and US$9.0M per year).

This strategy will be implemented during the 2021-2023 period with a gradual and efficient restart of operations once related goals and objectives have been achieved; prioritizing exploration over ore extraction to increase reserves in the long term. Importantly, suspension of Uchucchacua mining and ore processing activities will not affect progress related to the high-grade Yumpag project, expected to begin production in early 2024.

Silver	US$/Oz	16.79	11.10	51%	16.89	14.65	15%

3Q21 silver production increased by 103% year on year due to a 192% increase in ore treated despite lower silver grades. Third quarter 2021 silver production includes 28,945 silver ounces derived from tailings retreatment. 3Q21 Cost Applicable to Sales (CAS) was 16.79 US$/Oz; a 51% year on year increase due to a significant US$ 1.1 M increase in exploration expenses. COVID-19 related expenses also increased by US$ 0.4 M year on year.

Zinc	US$/MT	1,814	1,807	0%	1,760	1,803	-2%

El Brocal 3Q21 copper production was in line with the same period of 2020. Tajo Norte 3Q21 zinc production decreased by 60% year on year due to stripping delays with a negative reconciliation, resulting in decreased ore treated with lower ore grades and recoveries.

3Q21 Copper Cost Applicable to Sales (CAS) increased by 41% year on year, mainly due to increased exploration during the quarter to offset decreased 3Q20 exploration, with a related US$ 3.8 million increase in related expenses. 3Q21 zinc CAS was in line with 3Q20 CAS. COVID-19 related expenses also increased by US$ 2.5 M year on year.

General and Administrative Expenses

3Q21 General and Administrative expenses were US$ 15.6 million; a 7% decrease as compared to US$ 16.8 million in 3Q20.

Exploration in Non-Operating Areas

3Q21 Non-Operating Area exploration costs were US$ 3.5 million, compared with US$ 1.8 million in 3Q20. During the third quarter 2021, Buenaventura focused exploration primarily on its Emperatriz project, resulting in US$ 1.6 million in exploration costs during 3Q21. Increased exploration during the quarter is aligned with Buenaventura’s Strategy to focus on extending LOM.

Net gain (loss) for currency exchange difference

3Q21 currency exchange related net loss was US$ 31.9 million, compared with a net loss of US$ 0.8 million in 3Q20. The increased FX effect is due to a year on year weakening of the PEN relative to the US dollar (3.599 PEN/USD in 2020 vs 4.136 PEN/USD). SUNAT’s claim is registered in Peruvian Soles as part of ‘accounts receivables’ therefore, a higher exchange rate decreases the total amount when converted to dollars.

Finance Costs

3Q21 Finance Costs were US$ 26.7 million; a 260% increase as compared to US$ 7.4 million in 3Q20. This is mainly due to increased commissions associated with the guarantee letters issued to SUNAT as well as interest associated with by the Company’s July 2021 bond issuance.

Share in Associated Companies

During 3Q21, Buenaventura’s share in associated companies decreased to US$ -30.9 million, compared to US$ 23.5 million reported in 3Q20, comprised of:

Share in the Result of Associates (in millions of US$)	3Q21	3Q20	Var	9M21	9M20	Var

YANACOCHA

Yanacocha, which is 43.65% owned by Buenaventura, 3Q21 gold production reached 65,220 ounces; 28,469 ounces of which were attributable to Buenaventura. This represents an 18% decrease as compared to the 79,874 ounces produced in 3Q20; 34,865 ounces of which were attributable to Buenaventura.

Yanacocha reported a US$ 201.9 million net loss for 3Q21, compared to a US$ 18.6 million net income in 3Q20. 3Q21 CAS was 1,411 US$/Oz; a 36% increase compared to 1,036 US$/Oz in 3Q20. Net loss was adversely impacted by Yanacocha’s decision to sell all equipment and machinery at its Conga asset, with a related US$ 152.2 million impairment; US$ 66.4 million of which corresponds to BVN’s equity ownership position.

Capital expenditures at Yanacocha were US$ 39.0 million in 3Q21.

The Yanacocha Sulfides project

●	Full funds decision postponed to 2H22.
●	Investment of at least $500M in key activities including detailed-engineering, long-term acquisition, earth works and campsite through 2022.

CERRO VERDE

Cerro Verde (19.58% owned by Buenaventura) 3Q21 copper production was 102,382 MT, 20,046 MT of which is attributable to Buenaventura; an increase as compared to 98,718 MT produced in 3Q20; 19,329 MT of which was attributable to Buenaventura.

Cerro Verde reported 3Q21 net income of US$ 293.3 million, compared to net income of US$ 115.8 million in 3Q20. This is primarily due to a 56% year on year net sales increase, mainly due to a higher average realized copper price of US$ 4.07 per pound in the third quarter of 2021, compared to US$ 3.20 per pound in the third quarter of 2020. This increase was partially offset by a year on year income tax increase.

3Q21 capital expenditures at Cerro Verde were US$ 48.8 million.

COIMOLACHE (Tantahuatay operation)

Coimolache, which is 40.10% owned by Buenaventura, 3Q21 attributable contribution to net income was US$ 0.8 million, as compared to US$ 3.0 million attributable contribution to net income in 3Q20.

*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 (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

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 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.
