1Q22 Comments

Tambomayo:

• 1Q22 gold production exceeded first quarter 2022 projections due to a.) gold grade which was higher than anticipated and b.) production from a high-grade pillar which was carried forward from the fourth quarter 2021 to the first quarter 2022.
• 1Q22 silver production was below projections, partially offset by higher zinc and lead production for the quarter.

Orcopampa:

• 1Q22 gold production was above projections for the quarter due to higher than anticipated tonnage and grade

Coimolache:

• 1Q22 gold production was above projections for the quarter primarily due to favorable geological reconciliation of both increased tonnage and grade

La Zanja:

• 1Q22 gold production was below projections for the quarter due to lower than expected haulage fleet performance due to Peru’s rainy season.

Julcani:

• 1Q22 silver production was above projections for the quarter due to higher than anticipated grade.

Uchucchacua:

• Exploration tunneling and diamond drilling continues according to plan with an emphasis on the Nora-Geraldine orebody.
• Yumpag mine development began ramp-up during 1Q22 with a new contractor, also with exploration progressing as planned for the Camila and Tomasa orebodies.

El Brocal:

• Copper, lead and zinc production was in line with expectations for 1Q22.
• Silver production was below projections for the quarter due to lower than expected open pit grades.
• A landslide within the mine’s open pit occurred on March 19, 2022 resulting in the death of 3 workers. The exact cause of the landslide is under further investigation.
