When mining engineer Eddy Zhang took the stage at the 2025 AusIMM Underground Operators Conference in Adelaide, he was candid about the task at hand: “Today I’ll be presenting learnings from reorientating the Ernest Henry sublevel cave.
As ore grades decline and sustainability pressures rise, mining operations are being forced to find new ways to optimise resource extraction.
In the race to squeeze more value from every tonne of ore, the mining sector is increasingly looking to data-rich, high-resolution technologies that can keep pace with operational demands.
Explorers operating in Australia's greenfield and undercover regions face a common challenge: how to make confident decisions when the surface reveals so little.
As mineral explorers delve deeper into complex regolith terrains and undercover targets, the need for geochemical techniques that offer both precision and sensitivity has never been greater.
For Superintendent of Mine Planning Anne-Marie Ebbels, the expansion of BHP’s Prominent Hill operation isn’t just a technical upgrade—it’s a strategic shift in how the mine approaches longevity, productivity and sustainability.
At this year’s AusIMM Mineral Resource Estimation Conference (MREC2025) in Perth, one presentation stood out not just for its rigour, but for its challenge to long-standing assumptions in resource modelling.
In the ever-evolving field of mineral exploration, the challenge of interpreting surface geochemical data in complex terrains has long limited early-stage targeting success.
When a critical piece of underground infrastructure collapsed at Burkina Faso’s Yaramoko Mine, the clock was ticking.
In the remote Altai Mountains of eastern Kazakhstan, a centuries-old underground mine is undergoing a transformation.
