Ioan Sanislav

Associate Professor, Economic and Structural Geology
Head, Economic Geology Research Centre
Director, JCU Resources Technology and Critical Minerals Trailblazer

Ioan Sanislav is an Associate Professor in Economic Geology at James Cook University, Head of the Economic Geology Research Centre, and Director of JCU’s Critical Minerals Trailblazer. He is an economic and structural geologist with extensive experience in mineral exploration, ore-deposit geology, field geology, geological mapping, structural controls on mineralisation, mineral systems analysis and critical-minerals research.

Ioan works on a large portfolio of collaborative projects with industry and government partners in Australia and overseas. His research integrates field-based geology with advanced analytical, geochemical, isotopic, geochronological, geophysical and modelling approaches to improve mineral exploration, ore-body characterisation, vectoring tools, metallogenic models and project development. His work covers a diverse range of commodities and mineral systems, including lode gold, IOCG, SEDEX, sediment-hosted Cu-Zn-Pb-Ag systems, Cu-Au, porphyry Cu-Au, epithermal Au-Ag-Te, manganese, chromitite, ultramafic-hosted Ni-Co-Sc-Cr, REE-Nb-Ta, indium-bearing Sn-polymetallic systems and broader critical-minerals projects.

A major strength of Ioan’s work is the integration of academic research with direct industry experience. He has worked closely with mining and exploration companies, including as an embedded researcher with Geita Gold Mine, where he contributed to exploration strategy, target generation, geological mapping, QA/QC, exploration-database design, training of exploration geologists and integrated geological modelling. Through EGRU and the Critical Minerals Trailblazer, he develops applied research projects that address real exploration and mining challenges while supporting the training of Honours, Masters and PhD students for the minerals industry.
