Zach has 16 years experience in the mining industry in Australia and overseas, 11 of which were in operational roles.  Since moving into consulting practice in 2004, Zach has worked for numerous clients in a range of commodities.  For the last four years his particular focus has been on consulting to coal clients in the use of geostatistics within coal operations, particularly in operational resource estimation and coal quality control.. He is a member of the AusIMM and AIG. Zach is based in Brisbane, Australia.

Olivier Bertoli - Director and Principal, Geostatistics and Resource Evaluation                                                                               Download Full CV

Olivier’s high level training in applied mathematics, mining engineering and geostatistics from the Paris School of Mines is broadened by 14 years practical experience as a professional geostatistician.

Olivier has expert knowledge of the geostatistical software toolbox Isatis and is a specialist 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 in central Queensland, NSW and Indonesian coal deposits for Anglo Coal, Xstrata, Kogan Creek Mine, BMA and BHP Billiton since 2002. Olivier also has expertise in advanced geostatistical modelling: 2D methods, non-linear methods (Uniform Conditioning, Service Variables and MIK), conditional simulations (including pluriGaussian 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).

 

Clare Mawdesley - Principal Consultant, Resource Evaluation                                                                                                           Download Full CV

Clare has 17 years mining experience in mining geology, planning and geotechnical engineering roles. She has specific expertise in geotechnical and geological characterisation, numerical modelling, and medium to long-term mine design and scheduling. Clare has a B.Eng. (Hons) in Geological Engineering from RMIT University and a PhD from the University of Queensland. Her PhD work involved the application of a statistical approach to evaluate and improve existing empirical design methods for predicting instability and caving. She is a member of the AusIMM and AIG.  Clare is based in Tasmania.

Amanda joined Tenzing in April 2010 as Administration Officer and manages the day to day functions within the office including invoicing and accounts.

Associate Personnel

Jacques Deraisme –Associate Geostatistical Expert

Jacques Deraisme is the Technical Manager in charge of the consulting and training at Geovariances in Fontainebleau, France. After graduating as a Mining Engineer (Ecole des Mines de Nancy, 1969) he worked from 1972 to 1986 at the Centre de Géostatistique de l'Ecole des Mines de Paris where his research activities focused on stochastic and mining simulations, and from where, in 1978, he obtained his PhD. 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.

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.
