Buenaventura Announces First Quarter 2021 Production and Volume Sold Per Metal Results

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 1Q21 production and volume sold.

• Tambomayo:
  
  1Q21 gold production was below expectation due to continued Covid-19 related personnel restrictions resulting in less ore treated, as well as longer than expected maintenance works during the month of February. This was partially offset by higher gold grade mined during the quarter. 2021 guidance remains unchanged in light of a careful review of the Company’s short-term mining plan designed to accelerate mining in high grade areas during the year.
  
  1Q21 silver production was above projections for the quarter due to higher silver grades. 2021 guidance remains unchanged.

• Orcopampa:
  
  1Q21 gold production was below expectations due to less ore treated resulting from Covid-19 related personnel restrictions. Additional staff and resources will be allocated to expedite production for the balance the year. 2021 guidance remains unchanged.

• Coimolache:
  
  1Q21 gold production was in line with expectations. 2021 guidance remains unchanged.

• La Zanja:
  
  1Q21 gold production was in line with expectations. 2021 guidance remains unchanged.

• Julcani:
  
  1Q21 silver production was in line with expectations. 2021 guidance remains unchanged.

• Uchucchacua:
  
  1Q21 silver, lead and zinc production was below expectations due to lower production resulting from underground mine development delays, specifically delayed mine ramp-up. This was partially offset by 4.25 Oz Ag/MT in reprocessed tailings.

• El Brocal:
  
  Marcapunta’s copper production was above expectations with increased ore treated during the quarter due to the 2021 re-scheduled open pit production mining sequence, enabling Cu-ore production in Q1. 2021 guidance remains unchanged.
  
  Tajo Norte’s zinc production was below expectations due to polymetallic-ore production re-scheduled until later in the year. 2021 guidance remains unchanged.
