1Q22
-
Quarterly gold production increased 12.2% vs. 4Q21 mainly due to an increased rate of solution flow following the short term disruption caused in the prior quarter due to the increased silt in solution restricting filtering capacity.
-
Quarterly gold production decreased 48.0% vs. 1Q21 due to a lower volume of ore processed in line with the mine plan as a result of larger haulage cycles and a lower ore grade in line with expectations.
-
The gold ore grade in 2022 is estimated to remain in the range of 0.65-0.75 g/t.
