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.

Underground Operations and Development

Period	Diamond Drill (m)	Gallery Rehabilitation (m)	Underground Development (m)
T1	6 467	1 703	71.6
T2	4 572	903	290
T3	7 153	455	307
T4	11 059	1 052	554
Variations T4 vs T3	155%	231%	180%
Total YTD	29 251 m	4 113 m	1 222.6 m

Underground mine development experienced a major leap in Q4 with 554 meters completed (a 180% 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.
