Material Changes and Operational Performance
Production results varied significantly across assets compared to 2026 guidance:
- Outperformance:
- Uchucchacua & Yumpag: Silver production exceeded projections due to higher-than-anticipated grades.
- El Brocal: Copper, silver, and gold production exceeded projections due to higher grades from rescheduled stopes and improved recovery.
- Orcopampa: Gold production exceeded projections due to higher-than-budgeted grades.
- Tambomayo: Silver and lead production exceeded projections due to prioritization of higher-grade ore.
- Coimolache: Silver production exceeded projections; gold was in line.
- Underperformance:
- San Gabriel: Gold production was below projections as the mine entered a ramp-up phase with lower ore throughput during instrumentation and commissioning.
- Julcani: Silver production was below projections due to lower ore throughput and grades (gold slightly exceeded projections).
- Tambomayo: Gold and zinc production were below projections due to lower grades in mined areas.
