Commentary on Operations

Tambomayo: 2023 gold and lead production exceeded revised guidance, as grades within areas mined during 4Q23 were 40% higher than previously estimated. 2023 silver and zinc production were in line with revised guidance.

2024 Guidance: Buenaventura expects gold, lead, and zinc production at its Tambomayo operations to decrease year on year, with an expected ~10% decrease in annual throughput and lower gold, lead and zinc grades as the mining sequence migrates into lower grade areas. Increased silver grades within scheduled 2024 mining areas will partially offset the expected processing volume decrease, with an increased silver production relative to 2023.

Orcopampa: 2023 gold production slightly exceeded guidance, as ore extracted during the 4Q23 had higher than anticipated gold grades.

2024 Guidance: guidance reflects a year-on-year decrease in gold production with lower gold grades expected to be mined during 2024, as an increased percentage of ore will be mined from lower-grade secondary stopes near the previously mined adjacent primary stopes.

Coimolache: 2023 gold production exceeded guidance, as optimized leach pad space enabled higher-than-planned volumes of ore treated during 4Q23. This was partially offset by lower grade and longer percolation rates during 4Q23. However, it’s important to note that 65% of full year 2023 production came from the Tantahuatay NW-Ext pit which successfully achieved target production within its first year of operation.

2024 Guidance: Buenaventura expects a year-on-year decline in gold due to limited leach pad capacity, as environmental permits required for leach pad expansion remain pending with continued delays from the Peruvian environmental authority (SENACE). Buenaventura expects to receive relevant permits in the 1H24, enabling construction of the necessary components during 2H24. The Coimolache production plan combines fresh ore with re-leaching at the Tantahuatay main pad to offset this production gap.

---

Julcani: 2023 silver production underperformed slightly relative to adjusted guidance, primarily due to a negative geology reconciliation and a year-on-year decrease in treated ore. However, it’s important to note that gold and copper production from the Rosario sector began in December 2024.

2024 Guidance: the Company expects a year-on-year increase in silver production due to a ~10% increase in annual throughput with benefit of full ramp up relative to the same period in 2023 and noting a 10-day suspension of operations in February 2023. Exploration at Julcani will also continue during 2024, with exploration, mine development and batch processing campaigns within the Rosario sector resulting in 3k Oz gold and 250k Oz silver in expected production, in addition to production from the Achilla sector.

Uchucchacua: Buenaventura re-initiated Uchucchacua and Yumpag ore processing in the 4Q23 after the Uchucchacua processing plant had been placed under Care and Maintenance (C&M) since 3Q21. 2023 lead and zinc production surpassed guidance while silver production underperformed guidance due to a short-term planning adjustment and to prioritize processing higher value ore production at Yumpag.

2024 Guidance: Buenaventura expects a year-on-year increase in silver, lead and zinc production due to Uchucchacua's sustained operation throughout full year 2024. Moving forward Uchucchacua will also primarily treat polymetallic ore, with ore value balanced between silver, lead and zinc- as opposed to exclusively silver ore which was produced previously. Additionally, Buenaventura has optimized Uchucchacua’s operations, which is now operating at approximately ~800 tpd and the plan is to ramp-up to ~1,500 tpd by 4Q24.

Yumpag: Yumpag ore processing from the pilot stope began simultaneously with that of Uchucchacua in 4Q23. Yumpag 2023 silver production exceeded guidance, offsetting lower production at Uchucchacua. The increased silver production is due to the prioritization of high-grade ore at Yumpag’s pilot stope.

2024 Guidance: Buenaventura expects a year-over-year increase in silver production, primarily due to a higher volume of ore treated. Yumpag continued processing pilot stope ore through January 2024, after which mineral processing has been suspended until definitive operating permits are obtained, expected by the end of 1Q24. Yumpag is therefore expected to initiate mineral processing in 2Q24 to achieve the estimated guidance.

El Brocal: 2023 silver production exceeded guidance due to higher-than-expected silver grades at the El Brocal underground mine. Copper, gold, lead and zinc production were in line with revised 2023 guidance. Record 2023 copper production resulted from successful massive underground method migration completion, enabling El Brocal to ultimately achieve an average of 10.8 ktpd during the 4Q23, surpassing its targeted 10,000 tpd underground mine exploitation rate, also with benefit of the successful implementation of Buenaventura’s plan to increase production at its Marcapunta underground mine to offset the temporary suspension of mining activities at Colquijirca’s Tajo Norte Mine as was announced on October 3, 2023.

---

2024 Guidance: Buenaventura expects copper production to remain in line with 2023 as underground mine production ramp-up continues, partially offset by lower copper grades. The targeted 2024 underground mine exploitation rate for El Brocal will increase to 11,000 tpd from 10,000 tpd in 4Q23. 2024 gold production is expected to decrease slightly year-over-year due to lower grades, partially offset by increased volume of treated ore. A significant year-on-year decline in El Brocal silver and zinc production is expected in 2024 due to the temporary suspension of mining activities at Colquijirca’s Tajo Norte Mine. No lead production has been planned for the full year 2024.
