Mr Alexandre Diragitch
Principal Geologist
Rio Tinto

Geological setting, structural evolution, and mineralisation of the ouéléba iron ore deposit, Simandou, Guinea: Implications for Archean-Proterozoic crustal development and later supergene ore formation

9:20 AM - 9:30 AM

Biography

Alexandre Diragitch is a Principal Geoscientist with nearly 25 years of experience in exploration, mining, and resource development. He began his career in Brazil after completing a BSc in Geology and has worked in Australia since 2008. His technical background spans surface mapping, geophysical interpretation, mine geology, greenfield and brownfield exploration, 3D modelling, and resource evaluation. Alexandre completed a Master of Philosophy at Curtin University in 2014, focusing on nickel sulphide mineralisation in collaboration with CSIRO. He has held multiple senior geology roles and is passionate about regional exploration, integrating geology with mining operations, and mentoring developing professionals.
