Compañia de Minas Buenaventura S.A.A. (“Buenaventura” or “the Company”) (NYSE: BVN; Lima Stock Exchange: BUE.LM), Peru’s largest publicly-traded precious metals mining company, today announced 2Q21 production and volume sold.

• Tambomayo:
  
  
  
  2Q21 gold production was aligned with expected mine ramp-up for 2021 and was favorably impacted by more stable operations at Tambomayo’s processing plant. 2021 gold production guidance remains unchanged.
  
  
  
  2Q21 silver production was in line with expectations. 2021 silver production guidance remains unchanged.

• Orcopampa:
  
  
  
  2Q21 gold production progressed slightly below the planned ramp-up due to less ore treated during the quarter resulting from Covid-19 related personnel restrictions. Additional staff and resources have been re-allocated to expedite Orcopampa mine development and production for the balance of the year. 2021 guidance remains unchanged.

• Coimolache:
  
  
  
  2Q21 gold production was in line with expectations. 2021 guidance remains unchanged.

• La Zanja:
  
  
  
  2Q21 gold production was in line with expectations. 2021 guidance remains unchanged.

• Julcani:
  
  
  
  2Q21 silver production was in line with expectations. 2021 guidance remains unchanged.

• Uchucchacua:
  
  
  
  2Q21 silver, lead and zinc production was below expectations due to lower production from high grade Ag areas resulting from Covid-19 restriction-related delays in mine development, a slower than anticipated transition to narrow vein mining and a negative reconciliation. This was partially offset by increased production from polymetallic stopes and 4 Oz Ag/t tailings reprocessed during the quarter. Therefore, guidance has been updated to 6.0 – 7.0 M Oz Ag for 2021 with more conservative development and mining rate projections due to Covid-19 related restrictions. The mining plan is still under review.

• El Brocal:
  
  
  
  Marcapunta’s 2Q21 copper production was in line with expectations. 2021 copper production guidance remains unchanged.
  
  
  
  Tajo Norte’s zinc production was below expectations due to stripping delays with a negative reconciliation. 2021 zinc production guidance was updated to 40.0-45.0k mt.
