Greg Walker

 

Principal Geophysicist and Manager GeoIntrepid

Greg is responsible for GeoIntrepid Solution Services which includes the 2.5D Airborne EM Inversion processing service and the GeoModeller 3D modelling service.

Greg has over 30 years’ experience in the resources sector. He completed his BSc (Hons) at the University of Sydney and had his grounding in geophysics at the Bureau of Mineral Resources (now Geoscience Australia) in Canberra. He then spent six years with Aberfoyle Resources working on base metal projects in Australia and Indonesia.

Greg joined BHP in 1995 and spent 17 years with the company based in Melbourne, Cape Town, Moscow and Singapore working on a range of projects across all commodities on 5 continents. He also led the team interpreting FALCON data from the 4 systems on worldwide projects and later managed the global geophysics function for the Minerals Exploration group.

Greg has specialised expertise in the interpretation of airborne gravity gradiometry and airborne electromagnetics data. He has broad multi-commodity experience and has been involved in all stages of resource exploration ranging from province evaluation, target generation, prospect stage, feasibility, brownfields, and in-mine exploration.

He holds a B.Sc in Geology and Geophysics and has proven analytical ability in the fields of geology, geochemistry, geophysics and remote sensing and a successful track record in ore resource/reserve estimation with experience in a wide range of commodities.

Rod has demonstrated skills in the integration of multidisciplinary data in geographic information systems or image processing environments as well as the processing of ground and airborne magnetic and radiometric and other remotely sensed data. He also has many years of experience in software design and development with a strong focus on robust and user friendly interfaces. Rod is a highly motivated self-starter with excellent long term vision in exploration research and a proven record in report writing.

Evren Pakyuz-Charrier

Product Manager

Evren Pakyuz-Charrier holds a MSc in Geology from Orleans University where he worked on the design of the Cell Based Associations algorithm, the basis of an innovative mining predictivity method.

He has recently completed his PhD studies at UWA on 3D geological modelling uncertainty estimation.

His interest in implicit 3D geological modelling and geostatistics made him an early user of the GeoModeller API. He collaborated with IG to improve the API and further his own research work.

Evren joined IG early 2018 as Geology Product Specialist with a focus on continuous improvement of the modelling engine and user experience.

His research interests and skills range from geostatistics to GIS, geological 3D modelling, spatial analysis, mining predictivity, potential field geophysics and coding.

 

Rainer Wackerle

Manager, GeoIntrepid Namibia

Rainer Wackerle holds a Diploma (MSc. Equivalent) in Applied Geophysics from the Technical University of Berlin. He started his career at the "Büro für Geophysik” in 1990 performing environmental and engineering geophysical consulting in the area of Berlin and the former German Democratic Republic. This included waste disposal investigation, detection of hazardous waste, detection of UXOs and ground water investigation.

From 1993 to 1996 he worked as an exploration geophysicist with the ‘Mineral Prospecting Promotion Project’ of the Federal Institute for Geosciences and Natural Resources (BGR) seconded to the Geological Survey of Namibia. In this role he participated in the compilation of the Namibian regional airborne magnetic survey data.

In 1997 Rainer joined the Geological Survey of Namibia where he held the position of Senior, later Chief geophysicist. During this time he was responsible for the geophysical activities of the Survey, including quality control of more than 4.5 million line-km of airborne geophysical surveys and supervision of the seismological and magnetic observatories operated by the Survey in co-operation with other institutions.

In 2009 he established GeoIntrepid Namibia where he is currently the Manager. GeoIntrepid Namibia provides a range of services including gravity, magnetic and radiometric data processing, data compilations, quality control (QC), image processing and interpretation of ground, marine and airborne geophysical data, satellite imagery and hyperspectral data.
