1Q23
-
Quarterly gold production increased 2.0% vs. 4Q22 due to a higher ore grade as a result of the positive variation with the geological model. This was partly offset by the lower volume of ore processed which resulted from the longer than expected maintenance programme and delay in the preparation of stopes driven by the reduced availability of equipment. These factors are expected to improve in the coming months, thus increasing volumes of ore processed by 3Q23.
-
Quarterly gold production decreased 6.9% vs. 1Q22 mainly due to the lower volume of ore processed in accordance to the mine plan, mitigated by the higher ore grade as a result of the previously mentioned factors.
-
Quarterly silver production remained flat vs. 4Q22 mainly as a result of the higher ore grade, offset by the lower volume of ore processed.
-
Quarterly silver production decreased 30.8% vs. 1Q22 due to the lower ore grade as a result of higher dilution in narrow veins and decreased volumes of ore processed.
- The gold and silver ore grades for 2023 are estimated to remain in the ranges of 1.0-1.1 g/t and 150-160 g/t respectively.
