Researchers at the University of Queensland (UQ) have contributed to the development of a new hyperspectral imaging system that enables near real-time aerial mapping for mineral exploration and environmental monitoring.
The technology has been developed through the European-led m4mining consortium and has been recognised by the European Commission as a significant advance for the mining sector.
The project brought together research organisations and industry partners to create a drone-mounted hyperspectral imaging platform capable of processing complex aerial data immediately after a survey.
Instead of waiting weeks or months for results, exploration teams can access usable datasets as soon as a drone lands, allowing faster decision-making in the field.
Following successful validation in Australia and Europe, the technology has now been integrated into a commercial product by Norwegian imaging company Norsk Elektro Optikk AS under its HySpex brand, paving the way for wider adoption across the global mining industry.
Drone-based hyperspectral imaging speeds up exploration
The University of Queensland’s Sustainable Minerals Institute (SMI) contributed geoscience, remote sensing and industry expertise to the Horizon Europe-funded m4mining consortium, helping validate the technology through case studies in regional Queensland before final testing in Brisbane.
The drone-mounted system combines advanced remote sensing with sophisticated data processing to generate detailed three-dimensional models of survey sites while simultaneously identifying patterns in minerals, soils and vegetation.
These surface characteristics provide valuable insights into geological structures and potential mineral deposits below ground.
Unlike conventional drone-based hyperspectral systems, which typically require extensive post-processing before data becomes usable, the new platform performs complex calculations during flight.
This significantly reduces turnaround times, enabling exploration teams to evaluate survey results almost immediately.
International collaboration delivers market-ready technology
The m4mining consortium received €4.5m through Horizon Europe to develop advanced material characterisation technology for mineral exploration, extraction, re-mining and environmental monitoring.
The project is led by Norwegian research centre NORCE alongside imaging specialist Norsk Elektro Optikk AS, with the University of Queensland providing an important link between technology developers and the resources sector.
SMI established a minerals advisory board during the project, ensuring industry feedback informed the development process. This collaborative approach helped refine the system to better meet operational requirements before final validation.
The European Commission’s evaluation of the project concluded that the consortium had delivered a fully integrated, validated and market-ready solution for mining applications, highlighting its potential to transform the acquisition and use of hyperspectral data in complex operating environments.
Commercial rollout and future research
The technology developed through m4mining has now been incorporated into HySpex’s new commercial BiFrost hyperspectral imaging platform, which is expected to be launched publicly in the coming months.
The success of the project also highlights the value of international partnerships between universities, research organisations and industry in accelerating innovation for the mining sector.
Meanwhile, researchers at the UQ are continuing to expand the capabilities of hyperspectral imaging by developing methods that combine drone-acquired datasets with satellite observations.
The approach aims to improve the resolution and accuracy of satellite imagery, creating new opportunities for mineral exploration, environmental assessment and large-scale resource monitoring.
