Tailings management is moving centre stage as miners seek higher water recovery and lower storage risk from finely ground waste streams that can exceed 90 per cent of processed ore mass. Operators are increasingly deploying high-rate and high-density thickeners for liquid–solid separation, along with paste and filtered tailings systems, to cut decant pond volumes and improve beach slope control. These choices directly affect dam wall loading, seepage behaviour and closure design, forcing closer integration between process engineering, geotechnical design and long-term monitoring.

Rox Resources has secured final Works Approval for its 100 per cent-owned Youanmi gold project in Western Australia, allowing full-scale construction of the processing plant, tailings storage facility, wastewater treatment facility and onsite power station to proceed. The approvals package now covers all major environmental aspects of the mine, with mining, infrastructure and plant works already advancing across the site. Rox is targeting first gold production by mid-2027, signalling a firm development schedule for contractors, plant suppliers and tailings designers.

Regis Resources has confirmed it will not lodge a counterproposal for Vault Minerals, allowing Genesis Minerals’ binding $5.6 billion bid to proceed as the superior offer under Vault’s existing scheme implementation deed. Genesis’ all-scrip proposal, if approved by Vault shareholders and regulators, would create one of Australia’s largest gold producers by combining Genesis’ Leonora assets with Vault’s portfolio. For mine planners and project engineers, the enlarged group signals potential consolidation of capital budgets, mill throughput strategies and regional exploration programmes across the combined Western Australian gold operations.
