**Commentary on Operations**

**Uchucchacua:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Silver production exceeded
1Q26 projections due to higher than anticipated silver grades.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 1Q26 lead and zinc production
was in line with projections.

**Yumpag:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Silver production exceeded
1Q26 projections, driven by higher-than-expected grades.

**El Brocal:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Copper and silver production
exceeded projections in 1Q26, primarily due to higher grades from stopes which had been rescheduled to be mined in 1Q26 from 4Q25.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Gold production also outperformed
guidance, driven by higher-than-budgeted grades as well as improved recovery during the quarter.

**San Gabriel:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· San Gabriel entered the
ramp-up phase during 1Q26, with activities currently focused on the instrumentation of the grinding circuit and commissioning of tailings
filtration system. During this phase, operating parameters are being optimized, resulting in lower ore throughput for the quarter and
gold production below projections.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· With production volumes
continuing to ramp up, the Company expects to start recording sales volumes in 2Q26.

**Coimolache:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Gold production for 1Q26
was in line with projections.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Silver production exceeded
1Q26 projections driven by higher-than-anticipated grades and recovery.

**Julcani:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Gold production slightly
exceeded projections, primarily due to higher ore throughput from the Rosario area.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· However, silver production
in 1Q26 was below projections, reflecting lower ore throughput and grades.

**Tambomayo:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Silver and lead production
exceeded projections in 1Q26, primarily driven by the prioritization of higher-grade ore from the upper sections of the mine.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· However, gold and zinc
production were below projections, reflecting lower grades in the areas mined during the quarter.

**Orcopampa:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Gold production in 1Q26
exceeded projections, due to higher-than-budgeted grades.

**La Zanja:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Gold production in 1Q26
was in line with projections.
