**Commentary on Operations**

**Tambomayo:**

&nbsp;&nbsp;&nbsp;&nbsp;· 3Q25
 gold and silver production was in line with expectations. High-grade oxide ore processing
 successfully began, as was reported in 2Q25. However, the 2025 production plan has been updated,
 with part of the high-grade ore initially planned for 2025 production to now be processed
 in 2026. A higher volume of lead and zinc will be produced in 2025.

&nbsp;&nbsp;&nbsp;&nbsp;· 2025
 silver, lead and zinc production guidance has been updated accordingly. 2025 gold guidance
 remains unchanged.

**Orcopampa:** 

&nbsp;&nbsp;&nbsp;&nbsp;· 3Q25
 gold and silver production was in line with expectations. However, 2025 gold production guidance
 has been revised, as a higher volume of ore will be processed in 4Q25 as compared to the
 initial plan.

**Coimolache:**

&nbsp;&nbsp;&nbsp;&nbsp;· Gold
 and silver production exceeded expectations for 3Q25, as full capacity mine and leach pad
 production began in early September 2025 due to earlier than expected operating permit approval
 which was initially expected in late September 2025.

&nbsp;&nbsp;&nbsp;&nbsp;· 2025
 gold production guidance has therefore been revised. 2025 silver guidance remains unchanged.

**Julcani:**

&nbsp;&nbsp;&nbsp;&nbsp;· Gold
 and copper production at the Julcani mine is gradually increasing as the operation transitions
 to mining zones richer in these metals, partially offsetting decreased production from the
 Achilla zone which has historically produced lead and silver.

&nbsp;&nbsp;&nbsp;&nbsp;· 2025
 gold and lead guidance remains unchanged; silver guidance has been revised.

![](tm2528946d1_6kimg001.jpg)

**Uchucchacua:**

&nbsp;&nbsp;&nbsp;&nbsp;· 3Q25
 silver production was in line with expectations, reflecting the revised mine plan the Company
 initiated in 2Q25. Mining activities during 3Q25 remained focused on polymetallic stopes,
 a strategic decision that supports ongoing water pumping and ancillary works but which shifts
 targeted mining to polymetallic stopes, from the prior target of mining bottom-level stopes
 with higher silver content. Water pumping activities were completed during 3Q25, and ancillary
 works are expected to conclude in 4Q25. This enables the team to begin to backfilling the
 mine's bottom zones with tailings slurry during 4Q25, and access to higher silver-grade
 areas will be achievable in 2026 as part of the full year mine plan. This process is intended
 to reduce voids in previously mined areas at the bottom of the mine, enhancing their structural
 stability and conditioning nearby zones for future operations. These works are expected to
 be completed by 2Q26.

&nbsp;&nbsp;&nbsp;&nbsp;· 2025
 silver and lead production guidance has been updated accordingly. 2025 zinc guidance remains
 unchanged.

**Yumpag:**

&nbsp;&nbsp;&nbsp;&nbsp;· Silver
 production exceeded 3Q25 projections due to higher grades mined during the quarter. This
 improvement reflects the continued application of the Over-Drift-Fill (ODF) mining method
 which provides high ore recovery with enhanced selectivity while reducing surface subsidence
 and the amount of surface tailings, a mining approach that the Company began implementing
 in 2Q25.

&nbsp;&nbsp;&nbsp;&nbsp;· 2025
 production guidance has been updated accordingly.

**El Brocal:**

&nbsp;&nbsp;&nbsp;&nbsp;· Silver
 and gold production outperformed expectations in 3Q25, reflecting the Company's short-term
 strategy of prioritizing the processing of stockpiles with high precious metals content.
 During the quarter, the Company processed lead-silver ore previously classified as low grade,
 which was re-evaluated based on current market conditions and incorporated into the production
 plan. This material had significant silver content and copper ore throughput was therefore
 reduced, resulting in a slight decrease in copper production volumes for the quarter.

&nbsp;&nbsp;&nbsp;&nbsp;· 2025
 production guidance has been updated accordingly.
