1. Above 2023 projections are considered forward-looking statements and represent management’s good faith estimates or expectations of future production results as of September 2023.
2. El Brocal stockpiled ore mined from its open pit during the 1Q23. Lead and zinc ore are being treated at the processing plant starting in 2Q23. The underground mine will operate continuously throughout 2023.

3Q23 Comments

Tambomayo:

• Gold, lead and zinc production was in line with 3Q23 expectations. 2023 gold, lead and zinc guidance remain unchanged.
• Silver production was lower than expected during the quarter due to a lower than planned mining rate within the mine's upper zone, which required more extensive rehabilitation and support to enable access to high-grade ore. 2023 silver guidance has been updated.

Orcopampa:

• 3Q23 gold production was in line with 3Q23 expectations. 2023 gold guidance remains unchanged.

Coimolache:

• 3Q23 gold production exceeded expectations due increased treated ore and higher gold grades. Increased production was also due to increased ounce recovery and percolation times during the quarter, as the Company is now fully recovering gold placed on the leach pad during the first half of 2023. This is expected to stabilize during 4Q23, with production in line with 3Q23. 2023 gold guidance therefore remains unchanged.

Julcani:

• 3Q23 silver production was below projections due to a negative geology reconciliation and decreased treated ore. 2023 silver guidance has been updated.
• Exploration and preparation of Julcani’s Rosario sector, which lies below the 610 level, began during 3Q23. This new zone includes gold and copper which Buenaventura will begin processing during the fourth quarter 2023. The Company will also submit a related reserves and resources analysis by year end 2023.

Uchucchacua:

• Buenaventura submitted Uchucchacua’s updated mine plan to the Peruvian Ministry of Energy and Mines on August 28, 2023. Buenaventura initiated a short ore processing campaign at the processing plant, ensuring the plants operational readiness to take delivery of ore from Uchucchacua and Yumpag during the 4Q23 as planned. Exploration and mine development progressed as scheduled during 3Q23.

Yumpag:

• The Yumpag project’s Environmental Impact Assessment (EIA) was approved on September 7, 2023. The Company promptly submitted a request to the Peruvian Ministry of Energy and Mines to obtain the necessary authorizations to initiate the deposit’s exploitation. However, 4Q23 targeted production initiation remains unchanged, as resumed activities at the Uchucchacua processing plant also enables Buenaventura to perform metallurgical tests for up to 124,600 tons of ore from the Yumpag project’s pilot stope.
• Yumpag’s ore concentrates will be processed at the Rio Seco plant to reduce manganese content. The Rio Seco plant is scheduled to resume operations in November 2023.

El Brocal:

• Gold production was lower than expected during the third quarter due to mine plan rescheduling for the underground mine, to prioritize higher copper grades. 2023 gold guidance has been updated.
• 3Q23 silver production was in line with 3Q23 expectations. 2023 silver guidance remains unchanged.
• On October 3, 2023, Buenaventura submitted a notice to the Peruvian Ministry of Energy and Mines (MINEM) for the temporary suspension of mining activities at Colquijirca’s Tajo Norte mine for up to three years due to a delay of Colquijirca’s Modification of Environmental Impact Assessment approval.
• Lead and zinc production was lower than expected during the quarter as the 20x30 mill PPM was completed in September, earlier than originally planned, to proactively ensure certain detected anomalies were rectified, avoiding potentially compromising the transmission system. Lead and zinc production expected for 2023 will therefore be carried forward into early 2024. 2023 lead and zinc guidance has been updated.
• 3Q23 copper production exceeded projections as underground mine production ramp-up continued ahead of expectations during the quarter. Transitional ore from the open pit also had a higher than estimated copper content with improved metallurgical recovery. Buenaventura maintains its targeted underground mine 10,000 tpd exploitation rate for 4Q23.
