Australian Mines has appointed a specialist consultant team to complete the pre-feasibility study for its Flemington Scandium Project, targeting delivery in the first quarter of 2027. The study will retain a 60-tonne-per-year scandium oxide reference case while testing production scenarios of up to 180 tonnes per year.

Coda Minerals has reported average copper and silver extraction of 94.4% and 95.9% respectively from representative Emmie Bluff samples, strengthening the case for its preferred whole-ore chloride leach process. The preliminary laboratory results also suggest Elizabeth Creek site water is suitable for processing, although cobalt recovery, plant-scale performance and capital requirements remain unresolved.

Pursuit Minerals has started its first diamond hole at the Demasía tenement, testing whether lithium-bearing brines extend beyond the existing 1.264 million tonne LCE resource at Rio Grande Sur. Early packer tests recovered brine at shallow depths, but lithium assays are still pending.

American Tungsten & Antimony has started an ahead-of-schedule campaign to produce antimony flake at its Del Sol refinery in Nevada, using material from Arizona. The first physical demonstration of its proposed US mine-to-metal chain could generate samples for customer qualification and government discussions, although the underlying asset acquisition remains incomplete.

Pursuit Minerals has secured environmental approvals to relocate its pilot plant to Rio Grande Sur and drill a new 500-metre hole at Demasía. The company has also applied to build commercial-scale evaporation ponds for its planned 5,000-tonne-per-year operation, although that approval remains outstanding.

Legacy Minerals is progressing an optimised scoping study at its Mt Carrington project, leveraging a 39% increase in resource tonnes and a 69% jump in indicated resources. Results are expected in December 2026, aiming to assess the economics of a larger-scale operation.

Zicom Group anticipates a significant fall in revenue and profits for FY2026, citing completion of major EPC contracts and geopolitical headwinds, but sees improving prospects with renewed political stability and fresh tenders.

St George Mining bolsters its Araxá niobium and rare earths project with a $60 million capital raise, appoints Worley as technical adviser, and reports strong metallurgical test results underpinning its dual commodity strategy.

Anson Resources and JordProxa have successfully completed the first phase of non-thermal downstream processing test work, advancing the Green River Lithium Project closer to commercial production.

Argosy Minerals is progressing its 12,000tpa Rincon Lithium Project in Argentina with robust feasibility testwork validating its process flowsheet and securing a 40MW power supply, underpinning its upcoming Definitive Feasibility Study.

Hastings Technology Metals has accelerated its downstream rare earths strategy by progressing a 49% stake in a Thai hydrometallurgical plant, securing feedstock and doubling planned capacity. An updated Yangibana DFS reveals robust economics, underpinning near-term production and cash flow.

Pilbara Gold is pushing ahead with a major 50,000m drilling campaign at its 2.1Moz Mt York Gold Project, targeting resource expansion at depth and along strike. Meanwhile, drilling has resumed at the Roe Hills Project after an eight-year break, aiming to define a maiden resource.
