Additional Comments

• Tambomayo:
  
  Achieved pre-Covid operating levels since September.

• Orcopampa:
  
  Operated at pre-Covid levels for the duration of the quarter.

• Coimolache:
  
  Ramp-up process continued during July until August, and reached pre-Covid operating levels since September.

• La Zanja:
  
  Operating at pre-Covid levels since August.

• Julcani:
  
  Operating at pre-Covid levels since September, when Julcani also treated prior month inventories. September production therefore reached above-average levels.

• Uchucchacua:
  
  The only remaining Buenaventura mine not yet operating at pre-Covid levels. This is primarily due to a reduced workforce, and shortage of workers required to successfully operate at full capacity.

• El Brocal:
  
  Operated at pre-Covid levels for the duration of the quarter. During the quarter Plant #2 was halted for nine consecutive days in August as part of the Planned Preventive Maintenance (PPM) for this mine.

It is important to note that the Company’s third and fourth quarter mining strategy is to focus operations within high-grade areas to offset COVID-19’s adverse impact on operations.
