Commentary on Operations

Tambomayo: 2024 gold production exceeded revised guidance, primarily due to an increase in processed ore. 2024 lead and zinc production were in line with expectations. 2024 silver production underperformed slightly relative to adjusted guidance, primarily due to delays related to poor ground conditions at the high silver grade ore stopes which made extraction more challenging.

2025 Guidance: Buenaventura anticipates a decrease in gold, lead, and zinc production at its Tambomayo operations relative to 2024. The Company expects an approximately 40% decrease in throughput for the year, as well as lower gold, lead, and zinc grades as the mining sequence progresses into lower-grade areas. However, higher silver grades in the scheduled 2025 mining areas are expected to offset the decrease in volume processed, resulting in stable silver production, year-on-year.

Orcopampa: 2024 gold and silver production was in line with expectations.

2025 Guidance: Guidance reflects a year-on-year decrease in gold production as well as an approximately 45% reduction in annual throughput, partially offset by higher gold grades expected in the scheduled 2025 mining areas as some stopes from Pucarina and Nazareno veins come into production.

Coimolache: 2024 Gold production exceeded projections due to an accelerated percolation rate at the leach pad and to higher grades than was previously expected.

2025 Guidance: The Company expects a year-on-year increase in gold production due to the expansion of the leach pad, which will be ready to receive fresh ore starting in 2H25. Buenaventura expects to obtain the necessary permits in 1Q25 with expected construction in 2Q25 and the resulting resumption of fresh ore leaching in 3Q25. The Coimolache production plan combines fresh ore with low-grade stockpile ore for leaching on the Tantahuatay pad to offset the decreased production planned for the 1H25.

Julcani: 2024 silver production underperformed slightly relative to adjusted guidance, primarily due to the transition from silver into copper-gold stopes. 2024 gold production therefore exceeded revised guidance slightly, gradually increasing as the operation transitions to zones richer in copper-gold.

2025 Guidance: The Company expects a year-on-year increase in silver and gold production due to an approximately 20% increase in expected throughput for the year, driven by an increased contribution of ore extracted from the Socorro sector.

Uchucchacua: 2024 silver and zinc production was in line with expectations. 2024 lead production underperformed slightly relative to adjusted guidance due to lower than expected grades.

2025 Guidance: Buenaventura anticipates a year-on-year increase in silver, lead, and zinc production resulting from an approximately 20% increase in throughput for 2025. This is due to optimized operations at Uchucchacua, which is projected to increase to 2,000 tpd by year-end 2025 from 1,500 tpd currently.

Yumpag: 2024 Silver production exceeded projections mainly due to higher than expected grades.

2025 Guidance: Buenaventura expects a decrease in silver production year-over-year, primarily due to lower silver grades. However, this will be partially mitigated by increased ore volume processed, as 2025 represents Yumpag’s first full 12-months of production at 1,000 tpd; the operations’ maximum allowable throughput based on the environmental permit currently in place. Buenaventura has planned to apply in 2025 for mining extraction rate expansion, enabling these operations to achieve 1,200 tpd during 2026.

El Brocal: 2024 copper and zinc production was in line with expectations. 2024 gold and silver production exceeded expectations primarily due to better than expected by-product recovery from copper concentrate extracted from the underground mine.

2025 Guidance: Buenaventura expects copper production to remain consistent with 2024 levels as underground mine production ramp-up continues, partially offset by lower copper grades. The targeted underground mine exploitation rate at El Brocal exceeded the original 11,500tpd target, reaching 12,500 tpd in 4Q24. A significant decrease in El Brocal silver and gold production is expected in 2025 due to the full depletion of the remaining ore inventory from Colquijirca’s Tajo Norte Mine in 2024, as well as ongoing temporary suspension of mining activities at Tajo Norte Mine. There are no plans for lead and zinc production for 2025.

San Gabriel:

2025 Guidance: Construction and mine development at San Gabriel will continue as planned during 1H25. In 3Q25, Buenaventura will focus on ensuring the processing plant's operational readiness for commercial production. 4Q25 targeted production initiation remains unchanged, subject to final permitting and required approvals.
