2Q22
-
Quarterly gold and silver production decreased 10.7% and 24.5% vs. 1Q22, respectively, primarily due to a lower ore grade as a higher proportion of ore from the main Ciénega mine was processed, as opposed to processing ore from a satellite operation in the surrounding area with a higher average ore grade.
-
Quarterly gold and silver production decreased 28.1% and 24.9% vs. 2Q21, respectively, due to a lower volume of ore processed given the continued impact of the labour reform in Mexico, in addition to the lower ore grades.
-
First half gold production decreased 29.2% vs. 1H21, due to the lower ore grade year-on-year, and lower volume of ore processed for reasons explained above. First half silver production decreased 8.7% vs. 1H21 due to a lower volume of ore processed, mitigated by a higher ore grade.
-
Gold and silver ore grades for 2022 are expected to remain in the range of 1.20-1.40 g/t and 145-155 g/t respectively.
