Commentary on Operations

Tambomayo:

Gold, lead and zinc production was in line with expectations. 2024 guidance remains unchanged.

Silver production was below 3Q24 projections due to delays related to mine development and in the preparation of high silver grade ore stopes. 2024 remains unchanged.

Orcopampa:

3Q24 gold and silver production was in line with expectations. 2024 guidance remains unchanged.

Coimolache:

Gold production exceeded 3Q24 projections due to an accelerated percolation rate at the leach pad. 2024 guidance has therefore been updated.

During the 3Q24, Buenaventura filed for a leach pad expansion construction permit at Coimolache, which is currently pending with the Ministry of Energy and Mines. Approval is expected by the end of 1Q25, enabling the Company to begin construction in 2Q25 and to resume leaching fresh ore in 3Q25.

Julcani:

Gold and copper production at the Julcani mine is gradually increasing as the operation transitions to zones richer in these metals, successfully offsetting lower production from the Achilla zone which has historically produced lead and silver.

2024 guidance has therefore been revised to reflect increased gold production with lower silver grades.

Uchucchacua:

Silver and lead production was in line with expectations for 3Q24. 2024 guidance remains unchanged.

Zinc production exceeded expectations due to higher grades than was previously projected. 2024 guidance has therefore been updated.

Uchucchacua achieved 1,500 TPD average daily throughput in 3Q24, aligned with the Company’s targeted 1,500 TPD by year end 2024.

Yumpag:

Silver production was in line with expectations for 3Q24. 2024 guidance remains unchanged.

El Brocal:

Copper production was in line with expectations for 3Q24. 2024 guidance remains unchanged.

Gold and silver production exceeded expectations for 3Q24 due to increased volume processed during the quarter. 2024 guidance has therefore been updated.

All ore stockpiled in 2Q24 was processed during the 3Q24, enabling El Brocal to meet its targeted production for the first nine months of 2024. The average mining rate during 3Q24 was 12,000 tons per day, and the average mining rate for the first nine months of the year was 11,000 tons per day, aligned with the Company’s target for full year production to exceed 11,000 tons per day.
