Olivier Bertoli - Principal, Geostatistics and Resource Evaluation
View Full CV
Olivier's high level training in applied mathematics, mining engineering and geostatistics from the Paris School of Mines is broadened by 12 years practical experience as a professional geostatistician.
Olivier has expert knowledge of the geostatistical software toolbox Isatis (developed by Geovariances), and specialises in staff training in the form of hands-on co-piloting sessions. Olivier has extensive experience in the application of geostatistical techniques to coal resource modelling, primarily gained through project work on central Queensland and NSW coal deposits for Anglo Coal, BMA (South Walker Creek, Poitrel) and BHP Billiton between 2002 and 2006. Olivier also has expertise in advanced geostatistical modelling: 2D methods, non-linear methods (Uniform Conditioning, Service Variables and MIK), conditional simulations, multivariate analysis and non-stationary modelling. He is a member of the AusIMM and GAA.
Olivier shares his time between France and Australia, where he spends four to six months per year (based in Brisbane).

Since 1986, Jacques has worked for Geovariances (he was a co-founder) and conducted many geostatistical studies for mining and oil companies. Jacques has led numerous training courses in applied geostatistics.
Jérôme Poisson – Associate Senior Geostatistician
Jérôme Poisson is a Geostatistican at Geovariances in Fontainebleau, France. After graduating as with a Masters degree in Geophysics (Ecole de l'Observatoire des Sciences de la Terre – Strasbourg University, France) he worked as a geostatistician/geophysicist in Montreal, Canada. Jérôme joined Geovariances in 2005 and has been involved with consulting to Geovariances clients and technical Isatis support.
Henri Sanguinetti - Associate Expert Geologist-Geostatistician
Henri is a dual French/Australian citizen with almost 40 years of experience in geology and geostatistics. He is one of the true experts in the application of complex geostatistical concepts to practical mining situations; his knowledge of Uranium deposits in particular is world-class. He has just finished an audit of a Lead-Zinc-Silver mine in Morocco within the framework of his partnership with Tenzing. Henri is due to come to Australia in the future to run an in-house training for Tenzing consultants on Uranium geology and resource estimation and meet with some of Tenzing's clients.
Adam Stewart - Associate Senior Resource Geologist
Adam has 14 years experience in the coal industry, with expertise in exploration, mining operations, geological modelling and resource estimation. Adam's qualifications include a B.App.Sc degree in geology from the University of Southern Queensland and a M.EngSc degree in mine management from the University of New South Wales.
