When Laércio Bertossi took to the stage at AusIMM’s 2025 Mineral Resource Estimation Conference in Perth, he didn’t unveil a new machine learning model or simulation breakthrough.
In the remote Altai Mountains of eastern Kazakhstan, a centuries-old underground mine is undergoing a transformation.
Underground haulage is often regarded as a necessary bottleneck—an unavoidable compromise between ore delivery and operational congestion.
A serious workplace incident at Cadia East Underground Mine in June 2023 has triggered a sweeping safety review after a jumbo offsider suffered a traumatic arm amputation during routine drilling operations.
The 2025 South Australian State Budget has landed with all the fanfare of a damp squib for the state’s mineral exploration and mining sector.
When a major weather event halted production at Evolution Mining’s Ernest Henry Operations (EHO) in March 2023, it set the stage for a remarkable operational comeback that would go on to earn Matt Bouwmeester the Best Paper of the Conference award at the 2025 AusIMM Underground Operators Conference in Adelaide.
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.
When Sweden-based miner Boliden set out to futureproof its Renström underground operations for autonomous mining, it quickly ran into a persistent problem: water.
At the AusIMM 2025 Mineral Resource Estimation Conference, Dr Oscar Rondon, principal geostatistician at Datamine, tackled a question that has dogged mining professionals for decades: Is estimating recoverable resources still hopeless?
The talk revisited a decades-old challenge in resource estimation, combining Rondon’s clear communication with Assibey-Bonsu’s extensive experience in the mining industry.
A quiet revolution may be underway in the metallurgical processing world, and it starts not with a new orebody, but with the way water is removed from copper concentrate.
