Commentary on Operations

Tambomayo:

• Gold and silver production slightly exceeded projections for the first quarter 2025, primarily due to higher than expected ore volumes processed.
• Zinc and lead production also exceeded expectations due to increased processed ore volumes and higher-than-anticipated ore grades from stopes in the bottom section of the mine.

Orcopampa:

• 1Q25 gold and silver were in line with expectations.

La Zanja:

• 1Q25 gold production was in line with expectations.
• Silver production exceeded 1Q25 projections due to higher than anticipated solubility.

Coimolache:

• 1Q25 gold production was in line with expectations.
• Silver production exceeded 1Q25 projections due to higher than anticipated silver grades.

Julcani:

• Silver output for 1Q25 was below estimates, primarily due to lower processed volumes from the Achilla area, as well as reduced grades from the Estela area as a result of increased dilution resulting from softer ground in the majority of the new stopes.
• Gold production was in line with expectations.

Uchucchacua:

• Silver production was in line with 1Q25 expectations.
• Lead and zinc output did not meet guidance due to lower-than-expected grades, attributable to changes in the mining sequence and softer ground that resulted in higher dilution.

Yumpag:

• Silver production exceeded 1Q25 projections, driven by higher grades from early access to high-grade stopes.

El Brocal:

• Copper and gold production was in line with expectations for 1Q25.
• Silver production outperformed guidance, due to higher than budgeted silver grades as part of a short-term plan prioritizing mining blocks with high silver content.
