Average Grade: The average grade for the fiscal year stands at 4.18 g/t Au. The decrease in Q4 (2.1 g/t) reflects the processing of lower-grade development zones, typical of a transitional expansion phase in underground workings. Ounces Produced (Q4 vs Q3): 60 % of Q3 production, directly correlated with the lower grade during these three months, though partially offset by the increased mill throughput.
