Material Changes and Operational Updates
- Yumpag Mine: Silver production exceeded projections due to higher-than-expected grades. Management revised 2026 guidance upward. Post-quarter, approval was received to increase the mining rate to 1,200 tonnes per day (from 1,000).
- San Gabriel Mine: Continued ramp-up with optimization of operating parameters. Tonnage processing was constrained by tailings-management challenges, specifically at the filtration plant. 2026 guidance was revised downward to reflect these constraints and current recovery rates. Sales volumes began in 2Q26.
- Orcopampa Mine: Gold production slightly exceeded projections due to higher ore throughput. 2026 guidance revised upward reflecting higher grades in development areas.
- Tambomayo Mine: Silver production exceeded projections due to higher grades. 2026 guidance revised upward supported by exploration results and commodity prices.
- Other Operations: Uchucchacua, El Brocal, Julcani, La Zanja, and Coimolache reported production in line with projections with no changes to 2026 guidance.

Key Facts for Investor Verification
- Guidance Revisions: Verify the specific impact of the upward revisions for Yumpag, Orcopampa, and Tambomayo versus the downward revision for San Gabriel on the full-year consolidated outlook.
- San Gabriel Constraints: Monitor the resolution of tailings-management challenges and the timeline for full optimization of the filtration plant.
- Yumpag Expansion: Confirm the operational impact of the approved increase in mining rate to 1,200 tonnes per day starting in 3Q26.
- Financial Performance: Note that this filing lacks financial statements; investors must refer to the upcoming Form 20-F or quarterly earnings release for revenue, costs, and profitability metrics.
- Realized Prices: Compare the reported realized prices (e.g., Gold at $4,599/oz) against spot market averages to assess hedging or timing impacts.
