Fortescue has sold more than 40 tonnes of copper concentrate treated with its patented Toowong Process, a low-temperature, low-pressure hydrometallurgical circuit that removes arsenic from copper concentrates. Developed and tested over four years after Fortescue acquired the technology, the process targets a longstanding penalty element constraint that limits saleability of high-arsenic ores. Commercial deployment could materially change project economics for arsenic-rich copper deposits, enabling miners to convert previously marginal or stranded resources into exportable concentrate streams.

Core Lithium has reported its longest mineralised downhole intersection at the Blackbeard prospect within the Finniss lithium operation in the Northern Territory, with diamond drillhole NMRD104 returning 92m at 1.25 per cent Li₂O, including 73m at 1.45 per cent Li₂O. The thick, continuous spodumene-bearing pegmatite materially extends known mineralisation at depth and along strike, improving the potential for larger, more coherent underground or bulk open-pit mine designs. For resource modellers and geotechs, the interval supports tighter geological domaining and may justify updated pit shells and geotechnical slope assessments.

Minerals 260 has intersected 1.1m at 290g/t gold within the Bullabulling gold project, 25km south‑west of Coolgardie in Western Australia, with grade control drilling also returning multiple high‑grade intervals. The company says these results support confidence in the existing 6.2Moz mineral resource, derived from ongoing infill, grade control and extensional drilling across the deposit. For mine planning and geotechnical design, the tighter drill spacing and confirmed high‑grade zones should refine pit shells, scheduling and cut‑off grade assumptions.
