Westgold Resources plans a $100 million brownfields Meekatharra Expansion Plan in Western Australia to lift processing capacity from 1.8Mtpa to 2.9Mtpa, a 61 per cent throughput increase at its central gold hub. The scoping study centres on upgrading the existing Meekatharra plant rather than building a new facility, signalling higher utilisation of current crushing and grinding circuits and greater ore draw from regional underground and open-pit operations. For mine planners and plant engineers, the uplift will drive changes in pit scheduling, haulage profiles, and tailings storage requirements.

Further uranium mineralisation has been confirmed at Alligator Energy’s Big Lake uranium project in South Australia, where 33 aircore holes totalling 4,112m have been completed. Follow‑up drilling at Site 10 intersected uranium mineralisation associated with the interpreted redox boundary between oxidised and reduced sediments, strengthening the company’s roll‑front exploration model. For geologists and hydrogeologists, the results support a redox‑controlled, sandstone‑hosted system, guiding placement of subsequent step‑out holes and refinement of groundwater sampling and downhole geophysics.

Brightstar Resources’ first diamond hole to exceed 1000m at the Two Mile Hill deposit has intersected over 500m of mineralised tonalite, materially enlarging the interpreted host intrusion at its 2.9Moz Sandstone gold project in Western Australia. The 1039.2m hole is one of two completed so far in a four-hole, ~3400m extensional drilling programme aimed at testing depth continuity and lateral extensions of the tonalite-hosted system. For geotechnical and mine planning teams, the thicker intrusive body suggests potential for a larger, deeper bulk underground mining envelope than previously modelled.
