Council for Geoscience The Council for Geoscience is a science council that is mandated to be the custodian of all on and off-shore geoscientific information in SA.

It is also mandated to generate and provide geoscientific research. The Council for Geoscience (CGS) is one of the National Science Councils of South Africa and is the legal successor of the Geological Survey of South Africa, which was formed in 1912 by the amalgamation of 3 former Surveys, the oldest of which - the Geological Commission of the Cape of Good Hope - was founded in 1895. The Council for Geoscience was established in terms of the Geoscience Act (Act No. 100 of 1993), the Act was later amended in 2010, to establish the Geoscience Amendment Act (Act No. 16 of 2010). As a scientific research council, the CGS is 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. The Council has a national footprint in the country, with the Head Office located in Silverton, Pretoria and various other Regional Offices located in Polokwane (Limpopo), Cape Town (Western Cape), Pietermaritzburg & Durban (Kwazulu Natal), Port Elizabeth (Eastern Cape) and Upington (Northern Cape). Today, the Council is a modern institution, boasting excellent facilities and expertise, ranking among the best in Africa. The CGS provides the following diverse professional services:

- Geophysical Airborne and Ground Surveys,
- Geological Mapping,
- Seismology,
- Geochemistry,
- Engineering Geosciences (including Geotechnical Services),
- Mineral Resources Development including Mining and Minerals Services,
- Water Geoscience/Hydrological Services,
- Environmental Management and Rehabilitation,
- Marine Geoscience
- Spatial Data and GIS Services; and
- Regional Geological Surveys and Map compilations including Core Drilling Services.

The Council for Geoscience (CGS) continues to contribute to discussions on the future of mining in the continent at Africa Mining Week 2026, taking place in Cape Town from 14–16 October 2026.

On Day Two, Ms Siphelele Buthelezi, Executive Manager: Office of the Chief Executive Officer at the CGS, participated in a panel discussion titled “Leveraging Advanced Technologies & AI to Transform Mining Practices for Sustainable Growth.”

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.

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.

On the barrier to the adoption of AI in an African context, she stressed the importance of African solutions for African problems, highlighting data security, cloud infrastructure and data sovereignty as critical considerations when geological data is a strategic national asset.

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.

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.

The Council for Geoscience 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 Department of Mineral and Petroleum Resources (DMPR).

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.

The Council for Geoscience led panel discussion at the SAGA Conference 2026 opened with Ms Marinda Havenga highlighting the significance of the geophysical datasets hosted by the CGS and their value across various sectors.

Facilitated by Dr Thakane Ntholi, the discussion explored the state’s investment in geophysical data and impact of the data in various sectors.

Panellists shared key insights:

- Ms Stephanie Enslin highlighted the need to look beyond data availability and funding priorities, encouraging students and researchers to explore how geophysical data can address broader development challenges. She emphasised industry partnerships and data sharing as critical to transforming the field.

- Dr Siyanda Mngadi stressed the importance of raising the profile and impact of geophysics among all stakeholders, including political leaders. He called for accessible, pre-competitive geological data to support mining programmes and emphasised the need for incentives to encourage data sharing and transformation within the geophysics community.

- Mr Carlos Mudzielwana demonstrated the value of geophysical data in infrastructure planning, design and monitoring. He highlighted its role in guiding geotechnical investigations and informing sound foundation design, as well as assessing geohazards such as sinkholes, subsidence and landslides.

- Dr Emmanuel Sakala explored the role of artificial intelligence (AI) in transforming intricate sensor data into practical maps and models. He emphasised the importance of integrating AI with fundamental geophysical principles to produce scientifically robust solutions for the subsurface.

In closing, Dr Thakane Ntholi underscored the importance of enhancing and promoting the geophysical efforts that are crucial for development a sustainable future.
