Gold Duke Project Mineral Resource Update​

HIGHLIGHTS
• Updated Mineral Resource Estimate for the 100%-owned Gold Duke Project: 4.8 Mt at 1.8 g/t Au for 277,000 oz, reported at a 0.5 g/t Au cut-off (includes Inferred).
• Updated MRE (2025) breakdown (0.5 g/t Au cut-off):
• Measured: 1.6 Mt at 1.6 g/t Au for 81,000 oz
• Indicated: 0.45 Mt at 1.6 g/t Au for 23,000 oz
• Measured + Indicated: 2.0 Mt at 1.6 g/t Au for 104,000 oz.
• Total Resource (incl. Inferred): 4.8 Mt at 1.8 g/t Au for 277,000 oz.
• All Mineral Resources Estimates are reported within a A$7,000/oz RPEEE pit shell, supporting realistic mine planning and project optimisation.
• Improved modelling and estimation approach applied to enhance operational realism. Mineralisation remains open along strike and at depth, with multiple lodes recognised across both near-surface and deeper positions.
• Higher confidence in the mining-approved deposits (Eagle, Emu, Golden Monarch, and Gold King) supports ongoing technical optimisation and economic work as WGR advances Gold Duke into production.
• Grade Control and infill drilling completed: 33,980 m of RC drilling across the approved mining areas to improve ore delineation and reduce geological uncertainty.
• Metallurgical test work confirms excellent processing characteristics, with gold recoveries up to 95.2% via conventional CIL.
• WGR has a binding toll milling agreement with Wiluna Mining Corporation Limited (subject to Deed of Company Arrangement) for the treatment of Gold Duke ore at the Wiluna Processing Plant, located approximately 46 km from the Project via an existing haulage route.
