Umlando Undertook Its Monthly Archaeological Survey in Early Page 1 of 21 DESKTOP PALAEONTOLOGICAL ASSESSMENT AND CHANCE FIND PROTOCOL FOR THE PROPOSED NKOMAZI GAME RESERVE (PTY) LTD PROJECT. MACADAMIA FARMING ADJACENT TO NKOMAZI GAME RESERVE, NEAR TJAKASTAD, MPUMALANGA PROVINCE FOR CORE Environmental Services DATE: 13 December 2020 By Dr Gideon Groenewald Cell: 078 713 6377 Nkomazi Macadamia Agricultural Development CORE Environmental Services 13/12/2020 Page 2 of 21 EXECUTIVE SUMMARY Dr Gideon Groenewald was appointed to undertake a Desktop Palaeontological Assessment Survey and to develop a Chance Find Protocol document (CFP) for the proposed Nkomazi Game Reserve Macadamia Agricultural Project in the Albert Luthuli Local Municipality of the Gert Sibande District Municipality in the Mpumalanga Province. This Desktop Survey is done as preparation of a Chance Find Protocol since very large parts of this development fall in areas underlain by geological formations with a known low to very low sensitivity for Palaeontological Heritage. This Palaeontological Assessment forms part of the Heritage Impact Assessment (HIA) and complies with the requirements of the South African National Heritage Resource Act No 25 of 1999 (revised 2017). In accordance with Section 38 of the National Resources Act No 25 of 1999 (Heritage Resources Management), a HIA is required to assess any potential impacts on Palaeontological Heritage within the development footprint. The development site applicable to the application for the proposed Nkomazi Game Reserve Macadamia Agricultural Project in the Albert Luthuli Local Municipality of the Gert Sibande District Municipality in the Mpumalanga Province is underlain by Swazian aged metamorphic rocks of the Barberton Supergroup and granites of the Kaap Valley Granite Suite. No significant fossils are expected from the areas underlain by granite. If by any chance, excavation expose fossils, it will be very important that a suitably qualified Palaeontological Specialist be appointed to do a Phase 1 PIA and to implement the Chance Find Protocol document included in this report (Appendix A). The CFP document must then be included as part of the EMPr of this project, to record all unexpected fossils associated with the geological formations on site. It is recommended that: • The EAP and ECO must be informed of the fact that a low and very low palaeontological sensitivity is allocated to the study area. Nkomazi Macadamia Agricultural Development CORE Environmental Services 14/12/2020 Page 3 of 21 • No further mitigation for Palaeontological Heritage is recommended. If, however, any observations of possible fossils are made, the developer must appoint a suitably qualified palaeontologist to implement the Chance Find Protocol (Appendix A).

This Desktop Survey is done as preparation of a Chance Find Protocol since very large parts of this development fall in areas underlain by geological formations with a known low to very low sensitivity for Palaeontological Heritage. Legal Requirements This Palaeontological Assessment forms part of the Heritage Impact Assessment (HIA) and complies with the requirements of the South African National Heritage Resource Act No 25 of 1999 (revised 2017). In accordance with Section 38 of the National Resources Act No 25 of 1999 (Heritage Resources Management), a HIA is required to assess any potential impacts on Palaeontological Heritage within the development footprint. Categories of heritage resources recognised as part of the National Estate in Section 3 of the Heritage Resources Act, and which therefore fall under its protection, include: • geological sites of scientific or cultural importance; • objects recovered from the soil or waters of South Africa, including archaeological and palaeontological objects and material, meteorites and rare geological specimens; and • objects with the potential to yield information that will contribute to an understanding of South Africa’s natural or cultural heritage. It is an explicit statement in terms of this report, that the developer is aware of important geological features in this region and that the known geo-sites are being avoided with no impact that will cause damage to known geological heritage sites in this region. Nkomazi Macadamia Agricultural Development CORE Environmental Services 14/12/2020 Page 7 of 21 Aims and Methodology A desktop investigation is often the only opportunity to record the fossil heritage within the development footprint. These records are very important to understand the past and form an important part of South Africa’s National Estate. Following the “SAHRA APM Guidelines: Minimum Standards for the Archaeological & Palaeontological Components of Impact Assessment Reports” the aims of the Palaeontological Impact Assessment are: • to identify exposed and subsurface rock formations that are considered to be palaeontologically significant; • to assess the level of palaeontological significance of these formations; • to comment on the impact of the development on these exposed and/ or potential fossil resources and • to make recommendations as to how the developer should conserve or mitigate damage to these resources. Prior to a field investigation, a preliminary assessment (Desktop Study) of the topography and geology of the study area is made, using appropriate 1:250 000 geological

Abstract For well over a century and a half coal has played a vital role in South Africa’s economy and currently bituminous coal is the primary energy source for domestic electricity generation, as well as being the feedstock for the production of a substantial percentage of the country’s liquid fuels. It furthermore provides a considerable source of foreign revenue from exports. Based on geographic considerations, and variations in the sedimentation, origin, formation, distribution and quality of the coals, 19 coalfields are generally recognised in South Africa. This paper provides an updated review of their exploration and exploitation histories, general geology, and coal seam nomenclature and coal qualities. Within the various coalfields autocyclic variability is the norm rather than the exception, whereas allocyclic variability is much less so, and allows for the correlation of genetically related sequences. During the mid-Jurassic break up of Gondwana most of the coals bearing successions were intruded by dolerite. These intrusions are important as they may cause devolatilisation and burning of the coal, create structural disturbances and related seam correlation problems, and difficulties in mining operations.

  • Response to Letter of 24 April 2019
    Exemption Letter – Baberton Mines, Sheba East Prospecting Right Application Heidi Fourie – Palaeontologist Farm: Sheba Siding 939-JU in Ehlanzeni District Municipality, Mbombela Local Municipality, Mpumalanga Province. DMR: MP30/5/1/2/15389PR Protocol and Chance Fossil Find is included. The applicant, Baberton Mines (Pty) Ltd proposes to prospect an area 13 km north east of Baberton and adjacent to the Sheba Mine over a five-year period divided into five phases. Only the third phase will use some invasive techniques. A maximum of 12 holes will be drilled to a depth varying between 290-335 m. on 0.04 hectares. Four roads will access the drill sites. A total area of 0.19 hectares will be disturbed. The aim is to identify additional mineral resources for the existing Sheba mine such as gold, silver and verdite of the Kimberley Reef. Recommendation This letter serves as a Letter of Exemption. It is in compliance with The Minimum Standards for Palaeontological Components of Heritage Impact Assessment Reports, SAHRA APMHOB, Guidelines 2012. The development is underlain by the Baberton Supergroup. It has a Low Palaeontological Sensitivity, therefore there is a low possibility that significant fossils will be present in the bedrock of these geological units (Groenewald and Groenewald 2014*). The drilling of the 12 holes may grant palaeontologists an opportunity to investigate and document micro stromatolites and the presence of cyanobacteria if found during the investigation phase. The project does exceed the triggers in Section 3 of the National Heritage Resources Act, Act No: 25 of 1999 of listed activities. The drilling will take place in the Moodies Group.

  • Palaeontological Field Assessment of the Proposed Swaziland-Mozambique Border Patrol Road and Mozambique Barrier Structure
    PALAEONTOLOGICAL FIELD ASSESSMENT OF THE PROPOSED SWAZILAND-MOZAMBIQUE BORDER PATROL ROAD AND MOZAMBIQUE BARRIER STRUCTURE Prepared for: Royal Haskoning DHV Royal HaskoningDHV (Pty) Ltd trading as Royal HaskoningDHV Reg No. 1966/001916/0 Building No. 5 Country Club Estate 21 Woodlands Drive, Woodmead, 2191 PO Box 867, Gallo Manor, 2052, Gauteng, South Africa 05 February 2018 Prepared by: BANZAI ENVIRONMENTAL (PTY) LTD EXECUTIVE SUMMARY Royal Haskoning DHV has appointed Banzai Environmental (Pty) Ltd to undertake a Palaeontological Impact Assessment (Phase 1) assessing the palaeontological impact of the proposed Swaziland- Mozambique Border Patrol Road and Mozambique Barrier Structure. According to the National Heritage Resources Act (Act No 25 of 1999, Section 38), a palaeontological impact assessment is required to detect the presence of fossil material within the proposed development footprint and to evaluate the impact of the construction and operation of the barrier on the palaeontological resources. The proposed project and base camp is underlain by various sedimentary rocks of which the Quaternary and the Undifferentiated Karoo has a high Palaeontological sensitivity and the Zululand Group which has a very high palaeontological sensitivity. The various intrusive rocks have an igneous origin and is thus unfossiliferous and has a zero palaeontological sensitivity. As part of the Palaeontological Impact Assessment, a field-survey of the development footprint was conducted in February 2018 to assess the potential risk to palaeontological material in the proposed footprint of the development. A physical field-survey of the proposed development and camping site was conducted on foot and by vehicle and during this field survey, no fossiliferous outcrops were found in the development footprint.

  • Palaeontological Technical Report for Kwazulu-Natal
    PALAEONTOLOGICAL TECHNICAL REPORT FOR KWAZULU-NATAL 31 October 2012 Prepared by: Dr. Gideon Groenewald EXECUTIVE SUMMARY The geological history of Kwazulu-Natal covers over 3100 million years of Earth history. Rocks, containing fossils or traces of fossils provide information about the palaeo-environments that existed in the past and the fossil history is therefore part of the Natural Heritage of the Province. The aim of this report is to ensure a better understanding of the fossil heritage in South Africa and to make it clear that fossils are not restricted to the Main Karoo Basin. Although metamorphic provinces are usually non- fossiliferous, low grade meta-sediments of a localized occurrence in the Pongola Group contain good examples of bio-sedimentary stromatolites. Most fossils are hidden in the bedrock and developers will only be able to assess specific reference to fossils once the topsoil has been removed and excavation has exposed the bedrock. The report presented here must be used in conjunction with published geological maps and as such can be used by heritage and environmental assessment practitioners as well as private developers, to evaluate the potential impact of proposed developments on fossil heritage of the province. Rock units are ranked in terms of its palaeontological sensitivity according to a three-point scale, from which the appropriate action to be taken (if any) before or during development can be inferred. Present legislation makes provision for the protection of fossil heritage as part of the National Heritage legislation. Despite the comparatively good legal protection offered to palaeontological heritage in South Africa by the current legislation, hitherto this aspect of natural heritage has been largely ignored by developers and professional heritage managers alike, mainly due to confusion between palaeontological and archaeological heritage.

  • The Witwatersrand Basin, South Africa: Geological Framework and Mineralization Processes
    ORE GEOIDGY REVIEWS ELSEVIER Ore Geology Reviews 10 (1995) 67-94 The Witwatersrand Basin, South Africa: Geological framework and mineralization processes Laurence J. Robb *, F. Michael Meyer i Department of Geology, University of the Witwatersrand, Private Bag 3, Wits 2050, South Africa Received 19 December 1994; accepted 19 June 1995 Abstract The Witwatersrand Basin formed over a period of 360 Ma between 3074 and 2714 Ma. Pulses of sedimentation within the sequence and its precursors were episodic, occurring between 3086-3074 Ma (Dominion Group), 2970-2914 Ma (West Rand Group) and 2894-2714 Ma (Central Rand Group). Detritus was derived from a mixed granite-greenstone source of two distinct ages; the first comprises Barberton-type greenstone belts and granitoids > 3100 Ma old, and the second consists of the greenstone belt-like Kraaipan Formation and associated granitoids < 3100 Ma old. Subsequent granitoid plutonism was episodic and coincided with hiatuses in sediment deposition, but continued throughout the evolution of the basin. Many of the provenance granitoids are characterized by hydrothermal alteration, are geochemically anomalous with respect to Au and U, and may represent viable source rocks for palaeoplacer mineralization. Tectonically, the basin evolved in response to processes occurring within a Wilson cycle, associated with the encroachment and ultimate collision of the Zimbabwe and Kaapvaal cratons. Metamorphism of the Witwatersrand Basin occurred at ca. 2500, 2300 and 2000 Ma. The first two events coincided with the progressive loading of the basin by Ventersdorp and Transvaal cover sequences, whereas the last reflects intrusion of the Bushveld Complex and/or the Vredefort catastrophism. Mineralization is concentrated in the conglomerates of the Central Rand Group and is represented by a complex paragenetic sequence initiated by early accumulation of detrital heavy minerals.
