Frazer Bourchier, President and CEO, commented:

"2024 has been a transformative year as we built on the strong foundation from our two producing assets in premier jurisdictions. Our commitment to excellence remains steadfast with a focus on maintaining rigorous operational and safety metrics to enable robust cash flow. We are pleased to re-affirm that we will meet our 2024 production guidance. Our strong operating performance in 2024 allowed us to build a cash-rich balance sheet with no debt.

"Looking ahead to 2025, we expect to continue to generate robust cashflow from both gold and antimony production. Due to planned mine sequencing, we expect Costerfield's 2025 production to be 43,000 – 48,000 gold equivalent ounces followed by higher production in 2026. 2025 is a key mine development year at Costerfield with a planned investment of $18 – $20 million in sustaining capital, to enable mining flexibility, long-term growth, and sustained profitability.

"At Björkdal, gold production in 2025 is expected to remain consistent with 2024 levels, supported by stable processed grades and tonnage. Our plan continues to prioritize higher-margin underground material while leveraging the existing low-grade stockpiles to fully utilize the plant's 1.4 million tonne per annum capacity.

"Our planned exploration investment continues to underscore our commitment to replacing mine depletion, extending mine life, and pursuing near-mine discovery opportunities at both operations."

• Q4 and year-end 2024 production results will be reported on January 13, 2025;
