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.
