1Q23
-
Quarterly gold production decreased 16.9% vs. 4Q22 due to the lower recovery rate driven by higher leaching pads and the lower ore grade, partly offset by the higher volume of ore processed.
-
Quarterly gold production decreased 49.3% vs. 1Q22 due to the decrease in recovery rate as described above, and a lower ore grade and volume of ore processed.
-
2023 estimated gold ore grade remains in the range of 0.40-0.50 g/t, as the mine approaches the end of its operational life.
