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.

This collaborative agreement covers the involvement of the CGS within a deep drilling project entitled "Drilling into Seismogenic zones of the M2.0-5.5 earthquakes in South African gold mines (DSeis)” which was awarded by the ICDP and funded to an amount of 1 million USD.

This project stems from another similar project which was carried out under collaboration between the Japanese International Cooperation Agency (JICA) and the South African government. During the JICA project, the CGS was able to install 12 seismograph stations within the Carletonville mining region and thus assisted us in expanding our cluster networks to more mining regions in an effort to contribute to the safety in the mines.

In addition, the JICA project improved the amount of monitoring within the mines, and thus, when the big 5.5 magnitude earthquake occurred in August 2014, it was probably the most monitored large events which we have ever had. The CGS was one of the parties who could provide valuable data about this event and further enhanced our understanding. Together with in-mine seismic data and Japanese data, the combined data set offers opportunities for unprecedented detailed research in seismology to elucidate the seismogenic zone.

However, with all this data about the event there still remained a few questions unanswered. Such as, “Why did the event occur below the mining horizons?”, which is where this current ICDP project comes into play. The project involves drilling, borehole logging and core logging directly into the seismogenic zones to investigate the earthquake mechanism and associated activity and to learn more about underground water and geo-microbiology. The CGS plays a central role for core repository.

This is an international venture which involves scientists not only from Japan but also from Germany, USA, Switzerland, Israel, Australia and India.

“The CGS, as a national mandated authority on earth-sciences development, is proud to be part of this partnership with international protagonists in seismology. This ground-breaking partnership advances, not only the science, but the national developmental priorities”, articulates Mabuza.

South African Mineral Reporting Codes

SAMCODES


The SAMCODES, the South African Mineral Reporting Codes, set out the minimum standards, recommendations and guidelines for the Public Reporting of mineral related issues in South Africa. They currently comprise three Codes, two Guideline documents and an affiliated National Standard:

a. SAMREC: The South African Code for the Reporting of Exploration Results, Mineral Resources and Mineral Reserves
b. SAMVAL: The South African Code for the Reporting of Mineral Asset Valuation
c. SAMOG: The South African Code for the Reporting of Oil and Gas Resources
d. Commodity, or subject, specific guidelines/standards:
i. SAMESG Guideline: The South African Guideline for the Reporting of Environmental, Social and Governance parameters within the mining and oil and gas industries
ii. SAMREC Diamond Guidelines: SAMREC Guideline Document for the Reporting of Diamond Exploration Results, Diamond Resources and Diamond Reserves (and other Gemstones, where Relevant)

uth African Bureau of Standards.

The SAMCODES have wide application throughout the extractive industries. Attracting finance for exploration and mining ventures is a critical part of the resource business environment today, and there are a number of finance options available, including accessing private equity. With the increase in the number of non-listed (private) companies and individuals seeking to obtain financial assistance, it is important to appreciate that issues of public reporting are not confined to listed companies only.
Their use is not limited, however, to investors – financial and legal documents can benefit from internationally standardised principles and terminology such as Mineral Resource, Mineral Reserve, Feasibility Study and Valuation. Also, social, environmental and governance matters (Sustainability Reports) can be issued according to a consistent set of standards.
Interested and affected parties, in whatever shape or form, have a right to the highest standards of documentation and, if they wish, can request that such be prepared by “Competent Persons or Competent Valuators” in accordance with the relevant SAMCODE. In fact, all practitioners providing geoscientific reports are required to be registered with a professional and/or statutory body which requires that anything they produce to be in harmony with SAMCODES principles. Under all circumstances, if Exploration Results, Mineral Resources and/or Mineral Reserves are reported publically (as defined in the SAMREC Code of 2016), and if said report is claimed to have been compiled in accordance with any of the SAMREC, SAMVAL or SAMOG Codes, then the report and the author are subject to the minimum standards and requirements of the relevant Code as well as the complaints procedure of the SAMCODE Standards Committee (SSC).

The 2016 version of the SAMCODES was released in May and are applicable immediately (JSE-listed company documents, however, are only required to be compiled in accordance with the new codes from 1 January, 2017). The Codes can be downloaded freely at www.samcodes.co.za and further information can also be obtained regarding the SAMCODES Standards Committee (SSC), training schedules, complaints procedure as well as other relevant news items and applicable links.

The highlight of the Minister Zwane’s address was the announcement of a high intensity, integrated and multidisciplinary 10-year mapping programme at a scale of one in fifty thousand [1:50 000] nationwide. The programme will be a great platform in rebuilding and protecting the rich and unique geological heritage of South Africa. This will also be an incredible opportunity for the various competencies within the CGS to work as a collective in addressing grand challenges in South Africa and moving forward the interest of ordinary South Africans. The management of the CGS and its competencies give full support to this revitalised mapping programme which will for the greater part be aligned to the National Development Plan Vision 2030 and Presidential 9-point plan.

 

 

Report on unusual ground fire at Sehlakwane, Sekhukhuneland

by: P.J.A. Bosch, N. Moabi and S. Makubalo

1: Introduction

A report on a possible hazardous underground fire at Sehlakwane (see attachment) was received by the Council for Geoscience on 28 July 2016.

On receiving the details of the report, P. Bosch, N. Moabi and S. Makubalo decided to investigate the occurrence. The immediate thoughts on the details provided were that the area was or is underlain by naturally occurring peat and that it is possible that this peat has dried out due to the prolonged heat and drought. It is therefore possible that the peat may have caught fire. The extension of this possible peatland is not known and it might be that it extends into occupied property within the area. It was decided to investigate the area as soon as possible to determine whether in fact it is peat burning and if it is of concern that it might extend to occupied property. The following preliminary actions were proposed: A trench or trenches should be excavated in the vicinity (with safety as a concern) of the area that is burning to establish the nature of the material that is burning.

The CGS Field School celebrates 10 years with a bang

The Council for Geoscience Field School celebrated its ten year anniversary with the successful completion of the 2015 field mapping training programme. The growth and transformation of the field school programme over the decade has been significant. Initially, the field school was designed as a two-year programme linked to the Annual Technical Programme targeting mostly recently employed geoscientists. These scientists would spend their time at the Limpopo regional office benefitting educationally from the vast economic mineral deposits of the province (for example gold, platinum and copper) and the highly complex, high-grade tectonometamorphic terrane, the Limpopo Belt. During this time, the field school participants would work on map compilations and the writing of complementary map explanations. This work was undertaken in addition to courses on microscopy, GIS and 4x4 driving, all of which would provide the participants with the vital knowledge and skills needed to ensure a successful start to their careers.
