#### Fourth Quarter and Full year 2022 Results

Lima, Peru, February 28, 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 fourth quarter (4Q22) and full year (FY22) ended December 31, 2022. 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$).

#### Fourth Quarter and Full year 2022 Highlights:

&nbsp;&nbsp;&nbsp;&nbsp;• 4Q22 EBITDA from direct operations was US$76.9 million, compared to US$59.7 million reported in 4Q21. FY22 EBITDA from direct operations reached US$473.1 million; a significant increase as compared to US$204.4 million for the FY21, and includes US$300 million resulting from the sale of Buenaventura's stake in Yanacocha.

&nbsp;&nbsp;&nbsp;&nbsp;• 4Q22 net income reached US$68.7 million, compared to a US$222.3 million net loss for the same period in 2021. The 4Q21 result includes a net loss of US$301 million from discontinued operations, mainly due to the reclassification of Buenaventura's interest in Yanacocha. FY22 net income was US$602.9 million, compared to a US$262.8 million net loss for the FY21.

&nbsp;&nbsp;&nbsp;&nbsp;• 4Q22 exploration at operating units increased to US$27.2 million, compared to US$15.5 million in 4Q21. This increase was aligned with the Company's revised strategy to increase its focus on exploration in order to extend LOM. FY22 exploration at operating units increased to US$80.8 million, from US$56.4 million in FY21.

&nbsp;&nbsp;&nbsp;&nbsp;• Buenaventura's cash position reached US$253.9 million as of December 31, 2022. Net Debt decreased to US$484.6 million with an average maturity of 3.4 years.

&nbsp;&nbsp;&nbsp;&nbsp;• 4Q22 capital expenditures were US$58.8 million, compared to US$32.1 million for the same period in 2021. FY22 capital expenditures reached US$152.0 million, compared to US$90.3 million in FY21. FY22 CAPEX includes US$34.7 million related to the San Gabriel Project and US$30.4 million related to the Yumpag Project.

&nbsp;&nbsp;&nbsp;&nbsp;• On December 20, 2022, Cerro Verde paid a total dividend of US$250 million. Buenaventura received US$49.8 million relative to its stake in Cerro Verde. The total dividend received by Buenaventura in FY22 was US$79.1 million.

&nbsp;&nbsp;&nbsp;&nbsp;• Mining operations at La Zanja were halted in October 2022 when Phase 4 mining was completed. However, leaching will continue to the extent that this remains profitable while Buenaventura continues exploration related to the underground Cu/Au sulfide project.

&nbsp;&nbsp;&nbsp;&nbsp;• 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 shareholder value.

#### 2023 CAPEX Guidance

The company expects total CAPEX to reach between US$350 - 370 million during 2023. Sustaining CAPEX is estimated to be between US$130 - 140 million, also considering tailings management at El Brocal and a ~US$50 million investment in Yumpag. Growth CAPEX is estimated to reach between US$220 - 230 million, related to San Gabriel (~US$190 million) and Trapiche (~US$30 million).

**Operating Revenues**<br>

4Q22 net sales were US$246.4 million, compared to US$249.7 million reported in 4Q21; a slight year-on-year decrease resulting from decreased commodity prices and reduced volume sold of lead, zinc, and silver, which was partially offset by increased volume sold of copper.

4Q22 gold production at Tambomayo decreased 33% year on year, in line with the planned mining sequence. Workings were rescheduled, and mining method adjustments were made to maintain silver, lead, and zinc production during the quarter. Cost Applicable to Sales (CAS) increased to 1,129 US$/Oz in 4Q22 from 1,023 US$/Oz in 4Q21. This increase was primarily due to the lower gold grade of ore treated in 4Q22.

2023 gold production guidance is 35k – 40k ounces and silver production guidance is 1.9M – 2.2M ounces.

4Q22 gold production increased by 23% year on year due to the conclusion of Pampa Verde pit (Phase 4) pre-stripping which enables full access to the ore body. 4Q22 Cost Applicable to Sales (CAS) was 1,649 US$/Oz, in line to the 4Q21 1,665 US$/Oz gold production. CAS has remained consistent due to the fact that Buenaventura has opted not to continue with Phase 5 exploitation for the time being despite Pampa Verde pit Phase 4 stripping completion. Phase 5 mining has been postponed due to OpEx inflationary pressure. Mining activities at the Pampa Verde pit will be paused during 2023 to focus on sulfide deposit exploration beneath the pit. However, leaching will continue at La Zanja's San Pedro pad to the extent that this remains profitable.

4Q22 gold production at Coimolache decreased by 14% year on year, primarily due to permit-related leach pad constraints which resulted in decreased ore placement. Cost Applicable to Sales (CAS) increased to 1,676 US$/Oz in 4Q22, from 1,147 US$/Oz in 4Q21. This was due to increased costs of sales and exploration expenses.

2023 gold production guidance is 60k – 65k ounces.

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.

&nbsp;&nbsp;&nbsp;&nbsp;<br>

Yumpag project construction and permitting continue according to schedule. Production is subject to permit approval, which is expected to be granted during 2H23 to then begin ore production and haulage to Uchucchacua´s processing plant. Once adequate ore stockpiles have been reached, processing is expected to begin between 4Q23 and 1Q24.

2023 silver production guidance is 0.7M – 1.0M ounces for Uchucchacua and 1.6M – 1.8M ounces for Yumpag.

El Brocal 4Q22 copper production increased by 41% year on year due to increased ore treated and higher copper grades from both the Marcapunta underground mine and the Tajo Norte open pit mine. Zinc and silver production decreased by 51% and 41% year on year, respectively, as part as the planned transition from polymetallic to copper ore.

4Q22 Copper Cost Applicable to Sales (CAS) decreased by 12% year on year and 4Q22 zinc CAS decreased by 49% year on year due to increased head grade and improved metallurgical performance.

Buenaventura has recorded a US$16.4M write-off within its 4Q 2022 results related to inventories associated with low-grade polymetallic sulfide ore at El Brocal that has oxidized. This represents a one-time accounting effect and does not represent a cash outflow. This has been recorded within the Company's 4Q 2022 results as related metallurgical tests were completed from June to November 2022 which concluded that the inventory's sulfides ore has oxidized, adversely affecting its metallurgical performance and, therefore, its value.

**General and Administrative Expenses**<br>

4Q22 General and Administrative expenses were US$17.3 million; an 8% decrease as compared to US$18.9 million in 4Q21.

**Exploration in Non-Operating Areas**<br>

4Q22 exploration costs in Non-Operating Areas were US$3.2 million, compared with US$4.0 million in 4Q21.

**SAN GABRIEL Project**<br>

CAPEX guidance for San Gabriel has been updated and is now expected to reach ~US$190.0 million by year end 2023. Investments are expected to primarily be related to underground mine development and the construction of the definitive campsite.

Engineering and procurement work for offsite activities progressed as planned by a significant 64% and 83%, respectively, relative to the total targeted for project completion. This thereby reduces overall project uncertainty and potentially enables the recovery of some lost time related to this project relative to its targeted completion.

**CERRO VERDE (19.58% owned by Buenaventura)**<br>

4Q22 copper production was 115,131 MT, 22,543 MT of which is attributable to Buenaventura; a 7% increase as compared to 108,074 MT produced in 4Q21, 21,161 MT of which was attributable to Buenaventura. This is primarily due to a 9% increase in volumes of ore treated and a 3% increase in copper grade.

Cerro Verde reported 4Q22 net income of US$312.2 million, compared to net income of US$381.7 million in 4Q21. This is primarily due to:

i. An increase in cost due to an materials and supplies inflation

ii. A decrease in sales due to lower average realized copper prices.

4Q22 Cerro Verde capital expenditures were US$69.0 million.

**COIMOLACHE (40.10% owned by Buenaventura)**<br>

Coimolache reported a 4Q22 US$7.4 million net loss, compared to US$0.0 million in 4Q21.

#### 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, 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.
