Mineral Resource Evaluation Conference (MRE25)

Dr Julian Ortiz is the Mark Cutifani / Anglo American Chair in Mining Innovation at Camborne School of Mines, where he focusses on geostatistics and predictive geometallurgy, developing algorithms for numerical modeling of geoscientific and mine production data to model the mineral resources and mining processes, predict performance and manage risk, associated to all stages of the extraction and processing of the materials mined.

He received a B.Sc. in Mining Engineering from Universidad de Chile (Chile), and a Ph.D. in Mining Engineering, specialising in Geostatistics, from University of Alberta (Canada). Subsequently, he worked at Universidad de Chile, where he became Head of Department and led several large projects with public and private funding. He then moved to Queen's University in Ontario, Canada, where he was Associate Professor and Head of Department. Dr Ortiz also founded the startup Annapurna Suite in Canada, specialised on workflow automation and advanced algorithms in resource modeling, where he is currently Director and Principal Consultant.

Geologist, Master of Business Administration (MBA), Geo-Mining-Metallurgical Specialization and Vice President of the World Sampling Council: The International Pierre Gy Sampling Association (IPGSA).

Internationally recognised professional with 25 years’ experience in the mining industry (from Resources to Port & Marketing), performed at different technical and leadership roles in exploration, database management, mining, production, processing, sampling, geotec, modelling, structural geology, technological projects, and quality management programs, performed in multi commodities (Gold, Copper, Iron Ore, Coal, and Nickel), countries and companies.

~18 years’ experience on Sampling and the implementation of Quality Management Programs across the mining value chain (Exploration to Port and Marketing). International speaker on Sampling & QAQC, and author of dozens of publications related. Part of Technical Committee and Editorial Committee since 2011 at World Sampling Conferences.

Currently, Director Geoscience QAQC at AngloGold Ashanti, providing worldwide Sampling and Quality Management support across all the operations of the company (America, Africa and Australia) to proactively monitor and quantify the quality and representiveness of the samples and data supporting Reconciliation, Compliance to Plan, Metallurgical Balance and Production Accounting results and decisions.

Dr Glacialle Tiu is an Associate Senior Lecturer at the Division of Geosciences and Environmental Engineering, Lulea University of Technology. Her research focuses on integrating ore geology and mineral processing to advance the field of geometallurgy, where her core expertise lies in the comprehensive characterisation of complex ores and the integration of traditional and AI-based analytical techniques to support 3D modelling, simulation, and geometallurgical modelling.

Glacialle's key areas of specialisation include: Geological characterisation and geometallurgical modelling of complex polymetallic ores; Application of machine learning and data fusion in real-time ore tracking; 3D geological modelling and simulation using advanced software tools; Design and implementation of digital and gamified learning systems in mining education; and Multiscale analytical instrumentation, mineral processing, and ore variability assessment.

Glacialle earned her Ph.D. in Ore Geology from Lulea, where she focused on the geometallurgy of the Lappberget Zn-Pb-Ag-(Cu-Au) deposit in Sweden. 

Ian Glacken is a mining geologist and geostatistician with over 35 years post-graduate experience worldwide. He is a graduate of universities in the UK, the USA and Australia. Ian is an Executive Consultant at Snowden Optiro, based in Perth, Australia, and is a former Director of both Snowden and Optiro. Ian specialises in Mineral Resource audits and reviews, training, and reconciliation studies. He has been working with the Australian JORC committee on the generation of the 2025 JORC Code update.
