Mapping Australia’s vanadium future: geochemical and ML insights for explorers

Mapping Australia’s vanadium future: geochemical and ML insights for explorers

First reported on Australian Mining

30 Second Briefing

Mapping of Australia’s vanadium resources by University of Sydney PhD student Marliana Widyastuti is using soil geochemistry and machine‑learning analysis of legacy datasets to pinpoint prospective deposits for steel alloys and vanadium redox flow batteries. The work integrates multi‑element soil surveys, mineralogical characterisation and spatial statistics to distinguish vanadium hosted in titanomagnetite, shales and laterites across different regolith profiles. Outcomes are expected to guide targeted drilling, refine grade–tonnage estimates and de‑risk exploration in under‑sampled terrains.

Technical Brief

  • Similar machine‑learning workflows could be adapted to other critical metals where large legacy soil datasets exist.

Our Take

Vanadium appears in only 12 keyword-matched pieces across more than a thousand Mining stories in our database, signalling that Australian vanadium remains a niche but strategically watched space compared with iron ore, gold and lithium coverage.

Research-tagged items involving Australian universities, like this University of Sydney work on vanadium, often precede project-level announcements by several years, suggesting this mapping effort could feed directly into future project generation and targeting rather than near-term mine development.

For Australia, vanadium sits at the intersection of critical minerals policy and grid-scale storage ambitions, so systematic mapping work is likely to be used by state and federal agencies to prioritise exploration incentives and infrastructure planning in prospective regions.

From reactive to predictive mining safety: data and sensing priorities for engineers

Mining safety specialist David Coghlan, head of technology and product at TURCK, argues that connected sensing and control must shift mines from reactive alarms to predictive intervention as fleets, conveyors and fixed plant become more automated. He points to integrated proximity detection, real-time location and condition monitoring on mobile equipment, tied into site-wide networks, as the basis for predicting collision and entrapment risks rather than just logging incidents. For geotechnical and operations teams, this means designing safety systems around data quality, latency and interoperability, not just compliance with existing guarding and lock-out procedures.

Evolution becomes Carnaby’s largest shareholder: M&A and project signals for mine planners

Evolution Mining has become Carnaby Resources’ largest shareholder with a 13.7 per cent stake after acquiring the QIC Queensland Critical Minerals Fund’s ~37.9 million Carnaby shares as part of its proposed $213 million takeover. Evolution also issued about 2.6 million new shares to QIC, signalling continued use of scrip-based structures in Australian mid-tier M&A. For copper–gold project developers, the move points to stronger strategic interest from established producers in advanced exploration portfolios rather than greenfield assets.

Develop’s Woodlawn drilling: 15-year mine life implications for planners and geotechs

Develop Global’s latest underground drilling at the Woodlawn copper–zinc mine in New South Wales has returned intercepts grading up to 15.7 per cent copper equivalent (CuEq), supporting its Project DM15 plan to extend mine life from 10 to 15 years. The high-grade results, from step-out holes targeting depth extensions of existing lenses, suggest additional sulphide resources beyond the current reserve envelope. For mine planners and geotechs, this points to a longer stoping schedule, potential redesign of sequencing and backfill, and extended use of existing underground infrastructure.
