3Q21

  • Quarterly gold and silver production both decreased 7.1% vs. 2Q21 due to a lower volume of ore processed given the impact of the labour reform in Mexico leading to lower utilisation rates though we expect this to be a temporary factor.

  • Quarterly and year-to-date gold and silver production decreased vs. 3Q20 and YTD20 respectively due to the lower ore grades year-on-year, in line with the mine sequence.

  • The gold and silver ore grades for 2021 are expected to remain at the lower end of the given ranges of 1.30-1.40 g/t and 150-160 g/t respectively.

2021 Objectives

  • Continue strict cost control. 
  • Continue the exploration programme in the district, increasing resources and reserves.
  • Begin construction of the fourth tailings dam.
