Executive summary

• Definitive Feasibility Study (DFS) targets 962,000 oz mined and 880,000 oz produced over 10 years, averaging 88,000 oz per annum, with 98,000 oz per annum in the first five years and first gold expected in H2 2028.

• Significant upside potential exists from integrating over 800,000 oz of underground and refractory ore bodies, currently outside the DFS, into future mine plans.

• The project is underpinned by a well-drilled 80-km greenstone belt with 37 deposits, offering substantial exploration and expansion opportunities.

• Recent AUD 30 million capital raise will fund feasibility, an 80,000m exploration drilling program, and working capital.

• Approvals process is on track for a Final Investment Decision (FID) in Q2 2027.
