Registrations for AusIMM’s Mineral Resource Estimation Conference held in Perth in May 2025 have not yet opened. Stay tuned for updates on when registration will begin and why you should join us for this two-day showcase of Australasian excellence in resource estimation.
AusIMM is delighted to announce the return of the Mineral Estimation Conference in 2025. Global professionals are set to explore leading best practice in mineral resource estimation at the Optus Stadium in Perth, from 7-8 May 2025.
Following its highly successful inaugural event in 2023, MREC 2025 will bring over 500 geologists, geostatisticians, software solution providers and resources professionals from around the world to challenge the status quo of mineral resource estimation and share leading best practice examples.
Session topics will cover the latest advancements and leading practices in QA/QC and sampling, 3D geological and estimation domain modelling, geostatistical analysis, estimation, validation and risk analysis and reporting. Proposed themes include but are not limited to:
• The fundamental reasons for estimating mineral resources.
• The limitations of current estimation techniques and their real-world implications.
• How do different end uses require different resource estimation practices.
• What to do when things go wrong.
• Learning from past mishaps and failures to improve future practices.
• Is ‘best practice’ a limiting paradigm and can it evolve with industry needs?
In response to strong interest, the Parker Challenge, introduced as part of the 2023 conference, will also return in 2025. In 2023, the challenge examined ‘between person variance’ in resource estimation, showcasing diverse outcomes and approaches from participants using the same dataset, with the challenge winner awarded $55,000. More details on the 2025 challenge and the prize award will be announced on the AusIMM website.
The 2025 MREC committee is now inviting abstract submissions for presentation at the conference. Share your wisdom, expertise, and practical insights to help educate and advance the resource geology community.
AusIMM acknowledges the support of our 2025 Conference Sponsors: BHP, RSC, Datamine, Maptek, Entech, and Business Events Perth.
