The Council for Geoscience (CGS) is one of the National Science Councils of South Africa. It was established by the Geoscience Act (100 of 1993)and is the national custodian for the collection and curation of all onshore and off shore geoscience information in South Africa. It is mandated to investigate a wide range of surface and subsurface, onshore and off shore geoscience matters. These include, but are not limited to, geology, geochemistry, geophysics, engineering geology, economic geology, geohazards and geohydrology. The organisation performs these duties mainly through Government funds and, to a lesser extent, through collaborations with private and public institutions, including institutions of higher education. Furthermore, the CGS is also mandated to provide for the promotion of research and the extension of knowledge in the field of geoscience as well as the provision of specialised geoscientific services. It aims to use this information to develop geoscience solutions to real-world challenges.

Complete MT Solutions Inc. (CMTS) offers the full spectrum of services for electromagnetic (EM) imaging of the Earth using the natural source magnetotelluric (MT) technique for targets from 100s m to 100s km in depth.
Our team consists of five internationally-based scientists who are all experts in their disciplines with over 140 years of combined experience in MT between us. We work together with clients to further develop the method and achieve maximum results for all possible applications.
CMTS’s philosophy is that best outcomes from magnetotelluric surveying come from deep knowledge of the method. Starting with survey design then cost-effective acquisition followed by robust processing and response analysis leading to multi-dimensional modelling and inversion from which geology-constrained interpretations can be made.
CMTS can value-add to existing legacy MT data by undertaking re-processing, re-analysis, re-inversion and re-interpretation using our modern, proprietary codes and approaches.

The SAMERDI Strategy, as an outcome of the Mining Phakisa, provides a roadmap on how to work collectively towards technological solutions that will increase safety and productivity, and reduce costs to ultimately extend the life of mines by:

Improving the competitiveness of the sector and creating new opportunities for South African based companies to operate in areas along the entire value chain; and

Reposition South Africa as the world leader in mining RD&I by building human resource skills, capabilities, and capacities across industry, academia and the science councils, ensuring its sustainability.

The SAMERDI Strategy provides a roadmap on working collectively towards technological solutions that will increase safety and productivity, reduce costs, and ultimately extend the life of mines.

Thus the implementation of the SAMERDI strategy through collaboration and support from researchers (science councils and academia), government depart­ments, mining houses (individually and collectively), and organised labour unions can be the solution to the chal­lenges that beset the mining sector.

Andrea Viezzoli earned his Bachelor in Physics at Bologna University (Italy). After a short stint in atmospheric physics, he moved to the field of Geophysics and to Australia where he earned a Ph.D. from Monash University in environmental applications of (ground) IP. It wasn’t till he joined as Post Doc the hydrogeophysics group at Aarhus University that we really sank his teeth into AEM. He then left academia to manage Aarhus Geophysics Aps, where he focuses on virtually all aspects of AEM. Beside consultancy, he still finds time for R&D. The last couple of years saw him joining his two main research interests, working on modelling AEM data affected by IP for different applications.
