1Q22

  • Quarterly gold production decreased 5.7% vs. 4Q21 due to a lower volume of ore processed given the continued impact of the labour reform in Mexico and covid-related absenteeism.

  • Quarterly silver production increased 1.1% and 9.0% vs. 4Q21 and 1Q21 respectively due to a higher ore grade, partially offset by a lower volume of ore processed for the reasons explained above.

  • Quarterly gold production decreased 30.1% vs. 1Q21 due to the lower ore grades year-on-year, in line with the mine sequence and lower volumes of ore processed for the reasons explained above.

  • The gold and silver ore grades for 2022 are estimated to remain in the ranges of 1.20-1.40 g/t and 145-155 g/t respectively.
