    Mark Wall, the Company's President and Chief Executive Officer, commented:

    "Q1 is historically a challenging quarter for the operations. For Q1 of 2025 we saw the all- important total tonnes mined increase by 28% when compared to Q1 of 2024. As previously reported the first half of 2025 is focussed exclusively on stripping waste to reach the important high grade NEX orebody, and the improvements in mining performance have been a key focus area. Processing continued to go well, with a 15% improvement in Q1 2025 compared to Q1 of 2024. As we were treating low grade stockpiles while we strip waste to the NEX orebody we expected lower grades, although the stockpile grades performed below modelled grade with a processed grade of 0.82 carats per tonne. While the processing facility continued to perform very well, the low-grade stockpiles being treated resulted in low carat production for the quarter. During Q2 we will continue to work to find the best grade in the large stockpile we are treating, while we close in on accessing the high grade NEX orebody at the end of Q2"
