Practical magnetotellurics for minerals exploration
Dr. David Khoza
Technical Director at Integrated Geoscience Solutions
Dr. David Khoza is geophysicist who’s worked in minerals exploration, mining and geoscience research. After completing BSc Honours degree, David joined BHP Billiton’s mineral exploration division, conducting geophysical surveys primarily in Africa. David took a break and then back into academia to complete his PhD, which focussed on understanding the tectonic evolution of the Southern African lithosphere using magnetotelluric data. Following that, he joined Anglo American’s Technical Solutions department supporting several business units in mining, green and brownfield exploration and research efforts within Anglo American. He then joined SPECTREM AIR, primarily focused on airborne data processing, modelling, interpretation and research. David then joined Council for Geoscience’s Executive Management Team until May 2023 responsible for implementing the mapping programme. David is currently the Technical Director at Integrated Geoscience Solutions, doing consulting and geoscience research for mineral/energy exploration and groundwater sectors. He holds a BSc (Geology and Physics), BSc Honours (Geophysics) and a PhD (Geophysics) from the University of the Witwatersrand.
SHANE EVANS
Director of Moombarriga Geoscience
After graduating from Curtin University in 1998 with an honours degree in geophysics, Shane spent time with DeBeers Exploration Australia as a GIS specialist. His involvement in diamond exploration and large scale investigation developed his interest in magnetotellurics (MT).
Shane has now amassed 15 years of experience working with MT data beginning with a Master’s Degree in Geophysics at Queens University in Canada. This project involved a crustal investigation of Central Baffin Island using MT data in northern Canada under the guidance of Alan Jones. (see Evans, S.F., A.G. Jones, J. Spratt and J. Katsube, 2005.Central Baffin electromagnetic experiment (CBEX) maps the NACP in the Canadian arctic. Physics of the Earth and Planetary Interiors, 150, 107-122.) This project involved the acquisition, processing and modelling of approximately 40 sites of broad-band MT data.
In 2003 Shane moved to Johannesburg in South Africa and joined the DeBeers Geoscience Centre to continue research into the use of MT as a tool for mapping the lithosphere. DeBeers was the sponsor of the SAMTEX experiment a project that Shane was deeply involved with. (see Evans, R.L., A.G. Jones, X. Garcia, M. Muller, M. Hamilton, S. Evans, S. Fourie, J. Spratt, S. Webb, H. Jelsma, and D. Hutchins, 2011. The electrical lithosphere beneath the Kaapvaal Craton, Southern Africa. Journal of Geophysical Research – Solid Earth, 116). Shane was also responsible for numerous regional DeBeers surveys throughout southern and central Africa, Canada and India.
Bringing this experience and knowledge with him to Perth in 2005, Shane founded Moombarriga Geoscience.

About this event
Course details
This course will provide the interested geoscientists with the knowledge and skills necessary to effectively use magnetotelluric (MT) data for minerals exploration. Some of the topics covered will be a basic introduction to the MT method, processing, 2D and 3D inversion modelling. The hands-on component of the course involves using modern, interactive platform for the analysis and inversion of magnetotelluric (MT) data.
