Production Variance Analysis:

• Milled Tonnage (Q4 vs Q3): +160% in mill throughput capacity, driven by the ongoing training

of the underground workforce.

• 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.

increase compared to Q3). Gallery rehabilitation also showed a marked increase of 231% (1,052 m

compared to 455 m in Q3), which will help improve the number of available working faces in the future.
