4Q22
-
Quarterly gold production was down 3.3% and 13.9% vs. 3Q22 and 4Q21 respectively, due to a lower volume of ore processed as a result of the non-scheduled minor technical stoppages at the SAG mill, and lower productivity from new personnel at the mine, mitigated by a higher ore grade.
-
Quarterly silver production decreased 20.9% and 29.9% vs. 3Q22 and 4Q21 respectively, due to a lower ore throughput for the reasons explained above, and a lower ore grade in line with the mine sequence.
-
Full year silver and gold production were down13.5% and 23.3% vs. FY21 respectively, due to the lower volumes of ore processed and a lower gold 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.
-
The gold and silver ore grades for 2023 are estimated to be in the ranges of 1.0-1.1 g/t and 150-160 g/t respectively.
