2018 Production Comments

Gold Operations

• Orcopampa:
  
  As was previously announced on December 12, Orcopampa’s 2018 production was below the Company’s most recently released production guidance due to management’s strategic decision to temporarily cease production in order to focus on centralizing the operation, prioritizing the De-Bottlenecking Program over ore extraction.

• Tambomayo:
  
  2018 gold, silver and lead production was in line with the most recent guidance released. 2018 zinc production was slightly above the guidance provided.

• La Zanja:
  
  2018 gold production was in line with the most recent guidance released.

• Tantahuatay:
  
  2018 gold production was in line with the most recent guidance released.

Base Metals Operations

• El Brocal:
