Long-term Planning

Geologists break the model mould and ask what if we started resource estimation from scratch

What if resource estimation wasn’t just updated, but completely reimagined? At the AusIMM 2025 Mineral Resource Estimation Conference in Perth, two respected voices in the field—Jacqui Coombes and Paul Hodkiewicz—stepped away from PowerPoint slides and into a candid, thought-provoking dialogue that challenged the mining industry to rethink its most foundational assumptions.

How erosion models are busting gullies, predicting the future and helping miners design landforms that last centuries and pass the pub test

What if you could fast-forward a century to see whether your rehabilitated mine landform holds its shape or collapses into a network of gullies? At a recent seminar hosted by the Office of the Queensland Mine Rehabilitation Commissioner (OQMRC), one message rang clear: erosion and landscape evolution models are no longer just academic exercises—they’re digital crystal balls for mine closure planning.
