Strengthening international cooperation in geoscience. The Council for Geoscience (CGS) and France’s Bureau de Recherches Géologiques et Minières (BRGM) have signed a three-year Memorandum of Understanding (MoU) to advance scientific collaboration, knowledge-sharing and technical expertise. The agreement will support cooperation in geological mapping, mineral intelligence, water resources, natural hazard assessment and other key areas, reinforcing the role of geoscience in driving sustainable development across Africa. #TheGroundWeShare #OAGSGA2026

The CGS through its CEO, Mosa Mabuza is participating in @MiningWeekly Exploration Webinar titled “Rethinking Partnerships to Build Africa’s Exploration Pipeline”.

The @CGS_RSA and The National Institute for Geoscientific Research and Data Management (TNO) signed the Sub-Grant Agreement to support the implement of the recently concluded Memorandum of Understanding between the parties.

Ms Buthelezi emphasised that there is no panacea for transforming African mining, but that historical data mining, underpinned by digitisation and digitalisation, is one of the solutions. She further outlined how the CGS is focused on the integration of historical geological records with modern datasets and leveraging platforms such as the Virtual Core Library to unlock new insights and support exploration. #AfricanMiningWeek #Geoscience

The discussion explored how artificial intelligence (AI), geomapping, remote sensing, drones and other digital mining solutions are transforming mineral exploration, improving resource modelling, enhancing operational efficiency and supporting safer, more sustainable mining practices. #AfricanMiningWeek #Geoscience

Mawande Ncume presented on his research that provides understanding of the Mambulu Complex in South Africa, previously thought to be a remnant of ancient ocean floor. Field mapping and new 3D inversion modelling using airborne magnetic data revealed that it is, in fact, a subsurface saucer-shaped complex, representative of typical magmatic processes- effectively casting doubt on the the old theory. #19SAGA2026 #geophysics

Noluvuyo Dudumashe’s presented on her research which showcases innovative techniques for detecting concealed nickel, copper and lithium deposits in the Northern Cape. By combining satellite imagery, airborne magnetic surveys and drone-based scanning, the study identified a potential mineral-rich underground lava tube. This integrated approach supports more precise drilling, optimising exploration costs and resources while reducing the need for extensive excavation. #19SAGA2026 #geophysics

Emmanuel Chirenje presented research on “Integrated Geophysical and Geotechnical Analysis of a Rainfall-Induced uMgababa Landslide in KwaZulu-Natal.” The study combined geophysical and geotechnical methods to investigate the rainfall-triggered landslide, highlighting how integrated ground assessments can improve landslide risk prediction and support disaster prevention. #19SAGA2026 #geophysics

The @CGS_RSA is currently participating at the' Africa Mining Week 2026, taking place in Cape Town from 14–16 October 2026, showcasing its role in advancing geoscience research and unlocking Africa’s mineral potential. As part of the programme, Ms Siphelele Buthelezi, CGS Executive Manager: Office of the CEO, presented on “Unlocking Africa’s Mineral Potential Through Digital Geoscience.” Her presentation highlighted how the CGS is transforming legacy data into accessible, interoperable digital information through data acquisition, preservation, curation and digital repositories. Through its virtual data platforms, the CGS aims to support data-driven mineral exploration, resource modelling and informed decision-making for the future of mining. The CGS exhibition stand also welcomed various delegates, including Ms Ntokozo Nzimande, Deputy Director-General for Mining, Minerals and Policy Development at the @DMPR_ZA. #AfricanMiningWeek #Geoscience

Andisani Makhado presented research on “Geophysical Investigation of Surface Subsidence and Associated Mining Voids at Blaauwberg Barite-Lead Mine, Limpopo Province.” The study used gravity and electrical geophysical surveys to investigate road subsidence linked to the collapse of old underground mine workings, including Shaft 05, highlighting the importance of identifying hidden mining voids to support infrastructure safety. #19SAGA2026 #Geophysics

Joseph Matamela presented research on “Geological Characterisation of a Potential CCUS Site: Insights from Borehole Geophysics.” The study used borehole geophysical tools to assess the Ventersdorp Supergroup’s potential for carbon capture, utilisation and storage (CCUS), providing insights into rock integrity and its suitability for secure CO₂ storage. #19SAGA2026 #geophysics

Sinovuyo Myedeki presented research on “Structural Controls on Seismicity,” investigating ongoing seismic activity at the Cooke Mine Section in the Far West Rand, despite mining operations ceasing in 2017. The study aims to improve understanding of post-closure seismic hazards, supporting safer mine closure, ongoing monitoring and the protection of nearby communities. #19SAGA2026 #geophysics

David Ngobeni presented on “Integrated Geophysical Investigation of the Shu Shu Hot Springs, KwaZulu‑Natal, South Africa” David investigated the Shu Shu hot springs, exploring the underground mechanisms through aerial surveys and soil electrification. They discovered that large subterranean fractures serve as conduits for rainwater, which penetrates the Earth, gets superheated, and is expelled back to the surface, generating heat. #19SAGA2026

The @CGS_RSA is participating in the @SAGA_1977 Conference, taking place from 12–16 October 2026 in Cape Town. As a conference sponsor, the CGS will host a panel discussion titled “The State’s Investment in Geophysics as a Catalyst for Sustainable Future Development,” led by Dr Thakane Ntholi. Meet the panellists who will share their insights on the role of geophysics in driving sustainable development.

Today, the @CGS_RSA (CGS) tabled its 2025/26 Annual Report in Parliament, reflecting a year of progress, impact and key achievements. Explore the highlights and discover how the CGS continues to advance its mandate in support of South Africa’s sustainable development.

The @CGS_RSA is participating at the 21st SEISMIX 2026 International Symposium, taking place from 5-9 October 2026 with the theme “Deep Seismic Profiling of the Continents and their Margins.” During the second day of the symposium, Mr Joseph Matamela, CGS Scientist and Analytical Services Section Head: Petrophysics, gave a talk on the topic “Broadband 3D Seismic Imaging for Characterisation of a Proposed Carbon Storage Pilot Site, Leandra, South Africa.” In his talk, he discussed the use of broadband 3D seismic imaging in the characterization of the subsurface at the proposed carbon storage pilot site in Leandra, South Africa. The talk illustrates the contribution of advanced geophysical methods towards the better understanding of subsurface geological structures and evaluation of geological formations for carbon storage. Mr Matamela’s talk reflects the CGS’ contribution to the application of geoscientific knowledge, innovation and technology towards emerging carbon management strategies.
