14 WESTGOLD RESOURCES LIMITED GREAT FINGALL UNDERGROUND MINE In FY25 development at Great Fingall progressed to plan, with a dual focus on decline development towards the deeper, higher-grade production zones, and installing key dewatering and ventilation infrastructure. Simultaneously with project development, alternate early mining studies informed the viability of commencing early mining of the Great Fingall Flats in the March quarter. This shallow opportunity fell outside the scope of the original feasibility study which focussed on mining the deeper, higher grade virgin stopes. The stockwork mineralisation in the selvedge of the old mine workings is expected to repeat at depth, and will be drilled along with numerous other targets in FY26. On 26 June 2025, following a competitive process, global mining contractor, Barminco Limited was awarded a three-year underground mining contract for Great Fingall, with mobilisation completed in Q1 FY26. The appointment leverages Barminco’s underground mining expertise and allowed the Great Fingall team and equipment to be redeployed to some of Westgold’s bigger operations. BIG BELL UNDERGROUND MINE In FY25, production at Big Bell focussed initially on mining the Sub-Level Cave, before an asset review in Q2 identified a lowcost opportunity to recommence transverse caving and draw from existing drawpoints in the upper levels of the cave. The combination of the Lower Cave and Upper Cave mining substantially increased ore availability and provided an opportunity to pause the Big Bell Deeps expansion and take advantage of the significant material within the Upper Cave area.
