The Council for Geoscience can confirm that an earthquake occurred in the East Rand gold mine area on the 26 April 2018, at 08:26am South African Standard Time. The earthquake registered a preliminary 3.1 on the local magnitude scale as determined by seismograph stations of the South African Seismograph Network operated by the Council for Geoscience. The Council for Geoscience has immediately deployed seismologists to establish and confirm the basis of the event.

Council for Geoscience appoints a Chief Executive Officer

 The Council for Geoscience (CGS) has announced the appointment of Mr Mosa Mabuza as the Chief Executive Officer (CEO). The announcement was made this morning by the Chairperson of its Board, Dr Humphrey Mathe. The position was occupied by Mr Simon Sikhosana until his retirement in November 2016. Mabuza was subsequently seconded to the CGS by the Department of Mineral Resources to act as its interim CEO until the position was permanently filled. During his tenure on this role, he has managed to reprioritize geological mapping by championing the refocus of the organization towards a geo-scientific programme that seeks to map South Africa at a scale of 1: 50 000. This appointment comes into effect immediately.

On Monday evening of the 3rd April 2017 at exactly 19:40, a 6.3 magnitude earthquake, whose impact reverberated across South Africa has since had its epicenter located near the Kalahari Game reserve in Botswana (location coordinates -22.470 and 25.040). A network of seismic stations installed in South Africa and several neighbouring countries enabled a speedy and seamless affirmation of the epicenter.

The Council for Geoscience asks for R20bn for South Africa Mapping.

State-funded Council for Geoscience wants to undertake a geological mapping of the whole of SA but needs R20bn over 10 years to complete the project.

Less than 5% of the country is covered by geotechnical maps of a 1:50,000 scale, which provides the most clarity of geological resources.

The country has been fully covered in terms of 1:1,000,000 and 1:250,000 scale maps, and the aim is to cover it entirely with 1:50,000 scale maps.

CEO Mosa Mabuza noted that Namibia, Canada and Australia had fully mapped their countries with 1:50,000 scale maps and combined had attracted about 40% of the global mining exploration budget.

"Exploration activity is attracted by the availability of geological information. It is important to invest in the geosciences today to secure the future that we seek," Mabuza said. Mineral explorers required maps on a scale of 1:50,000.

Handover ceremony of geological maps to Saldanha Bay Municipality

The Council for Geoscience (CGS) has on Monday the 19th of June 2017 handed over geological maps to the Saldanha Bay Municipality. This, as the CGS is currently embarking on an intensive, integrated and multidisciplinary 10 year geological mapping programme that will see the country mapped at a scale of 1:50 000. The announcement was made early this February at the Mining Indaba by the Minister of Mineral Resources, Mr Mosebenzi Zwane. Accordingly, this sets the tone for the CGS as it begins to integrate the pockets of geological information that exist, as stipulated in its plan of action of the 10 year mapping programme. The map sheets, which cover the Vredenburg, Velddrif and Saldanha areas, were compiled as part of the 1:50 000 scale map series, based on aerial photographic and field mapping that was completed some years ago  led by a former employee of the CGS and now retired geologist Dr Peter Siegfried, and Dr Dave Roberts (deceased). The cartographic work was undertaken by Ms Elmi Pretorius (also former employee) and others at the CGS Head Office. Prior to the actual handover, Dr Siegfried painstakingly explained the geology of the areas covered by the maps. The maps accompanied by a sheet explanation sheet that provides a description of the geological units and their history of formation, were handed over to the Executive Mayor of the Saldanha Bay Municipality, Councilor Marius Koen.

Highlights of the CGS participation at the PDAC 2017 Conference, Toronto Canada

The SA delegation at the PDAC

The Council for Geoscience (CGS) constituted the delegation of Department of Mineral Resources (DMR) to the Prospectus and Developers Association Conference (PDAC) in Canada. The conference and trade show is held annually during the first week of March at the Metro Convention Centre in Toronto, focusing on the development of junior to mid-tier mining value chain development, spanning exploration (geological information), development, financing, services, legal, and so on. The DMR led the South African delegation supported by the Department of Trade and Industry, Mintek, South African Diamond and Precious Metal Regulator, the CGS as well as the SA High Commission in Canada. The conference officially commenced on Sunday the 5th and continued till Wednesday the 8th of March 2017. The South African government safeguarded a strategic position at the trade show and maintained a strong brand presence while promoting the country as the ideal mining investment destination.

An earthquake occurred on the 28th January, 2018, at 18:03 South African Standard Time, on the Indian Rift at 53.10°S and 9.49°E approximately 2200 km southwest of Cape Town, with a moment magnitude of Mw~6.5. This event was located and analysed by partner networks in the Indian Ocean Tsunami warning System, e.g., Geofon Potsdam, Germany.

The mechanism of the earthquake is interpreted as strike slip hence, also considering the moderate magnitude and distance to the South African coast, the probability of a tsunami at South Africa is deemed insignificant. There have since been two more earthquakes (possibly aftershocks) that have been reported to have occurred in the same area in the past 11-12 hours. The two earthquakes could be linked to this one and also caused by the same mechanism. The locations of these earthquakes (as indicated above) are still to be reviewed by a seismologist.

The CGS partners with international stakeholders to implement the bilateral agreement and implement a project on “Drilling into Seismogenic zones of the M2.0-5.5 earthquakes in South African gold mines”.

DSC 0735On Friday 17 February 2017, the Acting CEO of the CGS, Mr Mosa Mabuza hosted Professor Hiroshi Ogasawara from Ritsumeikan University, Japan. The purpose of this meeting was in furtherance of the collaborative agreement between the Ritsumeikan University, the CGS and the International Continental Scientific Drilling Program (ICDP), especially within the context of the MoU recently signed between the DMR and the Ministry of Economy, Trade and Industry of Japan (METI) at the 2017 Mining Indaba.

Seismic disturbance in the West Rand gold mining area on Tuesday, 23 January, 2018 at 17:47

The South African National Seismograph Network automatic locator detected a seismic disturbance in the West Rand gold mining area on Tuesday, 23 January, 2018 at 17:47 South African Standard Time. The event had a primary magnitude of M=2.8. This is an automatic location and magnitude which may change once  reviewed by a seismologist.

Moderate seismicity had occurred before in the West Rand and Far West Rand gold mining areas with four events of magnitude M=3.9 from 2000 till date; the list of these previous events is given below:
