1. 2022 outlook projections shown above are considered forward-looking statements and represent management’s good faith estimates or expectations of future production results as of October 2022.

3Q22 Comments

Tambomayo:

• 3Q22 gold, lead and zinc production exceeded expectations due to an increase in grade and metallurgical recovery. 2022 guidance has subsequently been updated.
• 3Q22 silver production was in line with expectations for the quarter. 2022 guidance remains unchanged.

Orcopampa:

• 3Q22 gold production exceeded expectations due to an increase in treated ore and higher gold grades. 2022 guidance has been updated.

Coimolache:

• 3Q22 gold production was in line with expectations for the quarter. 2022 guidance remains unchanged.

La Zanja:

• 3Q22 gold production was below expectations for the quarter. 2022 guidance has been updated to reflect slower than expected gold extraction from the leach pad, requiring a portion of the expected 2022 production to carry forward into 2023.
• As was previously announced, Pampa Verde open pit production will conclude by the end of October 2022. Nevertheless, leaching will continue at La Zanja’s San Pedro pad for as long as this remains profitable. Copper sulfide exploration will continue within La Zanja's operational footprint.

Julcani:

• 3Q22 silver production exceeded expectations due to increased treated ore and higher silver grades. 2022 guidance has therefore been updated.

Uchucchacua:

• Exploration and mine development continues as planned at the Uchucchacua mine. The 2H23 target to resume production remains unchanged.
• Yumpag project construction and permitting continue according to schedule. The 1H24 target to begin production remains unchanged.

El Brocal:

• 3Q22 lead and zinc production exceeded expectations due to an increase in grade and metallurgical recovery from open pit´s low-grade stockpiles. 2022 guidance has subsequently been updated.
• Rehabilitation works are progressing as planned at El Brocal’s western wall due to the previously announced March 2022 landslide. Production within the pit continue as planned outside of the area in process of rehabilitation.
• 3Q22 gold exceeded expectations due to an increase in grade and metallurgical recovery from the underground mine. 2022 guidance has subsequently been updated.
• 3Q22 copper and silver production was in line with expectations for the quarter. 2022 guidance remains unchanged.
