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 .

Baberton lies 50 km to the southwest of Kaapmuiden, in the Kaap Valley, at the foot of the . The area is famous for its lode-gold mining that started with the gold rush in 1884 and created a boom town for a few years. Notable events were the discovery of the fabulous Golden Quarry deposit on Sheba Mine and the establishment of legendary Eureka City. Products mined here are talc, ornamental stone, verdite, and asbestos (Norman and Whitfield 2006).

The Onverwacht Group lies at the base (7 km thick) of the Fig Tree Group and is the oldest group of rocks in the Baberton area. It has been divided into the Tjakastad and Geluk Subgroups with 6 Formations (Zwartkoppie, Kromberg, Hooggenoeg, Komati, Theespruit, Sandspruit). The Fig Tree Group (2.5 km thick) is present in the Sheba Hills consisting of the Schoongezicht, Belvue Road and Sheba Formations. The Moodies Group (2.5 km thick) is named after the Moodies Hills divided into the Baviaanskop, Joe’s Luck and Clutha Formations (Kent 1980). Its age is estimated at 3 550 million years and the Moodies and Fig Tree Groups may contain micro stromatolites (McCarthy and Rubidge 2005). Cyanobacteria have been described from the Zwartkoppies Formation of the Onverwacht Group (MacRae 1999).

Declaration (disclaimer) I, Heidi Fourie, declare that I am an independent consultant and have no business, financial, personal or other interest in the proposed development project for which I was appointed to do a palaeontological assessment. There are no circumstances that compromise the objectivity of me performing such work.

I accept no liability, and the client, by receiving this document, indemnifies me against all actions, claims, demands, losses, liabilities, costs, damages and expenses arising from or in connection with services rendered, directly or indirectly by the use of the information contained in this document.

It may be possible that the Exemption Letter may have missed palaeontological resources in the project area as outcrops are not always present or visible on geological maps while others may lie below the overburden of earth and may only be present once development commences.

This report may not be altered in any way and any parts drawn from this report must make reference to this letter.

Protocol for Chance Finds and Management plan This section covers the recommended protocol for a Phase 2 Mitigation process as well as for reports where the Palaeontological Sensitivity is LOW; this process guides the palaeontologist / palaeobotanist / ECO on site and should not be attempted by the layman / developer. As part of the Environmental Authorisation conditions, an Environmental Control Officer (ECO) will be appointed to oversee the construction/prospecting activities in line with the legally binding Environmental Management Programme (EMPr) so that when a fossil is unearthed they can notify the relevant department and specialist to further investigate. The ECO should familiarise him- or herself with the applicable formations and its fossils. The Evolutionary Studies Institute, University of the and Ditsong: National Museum of Natural History, Pretoria have good examples of fossils.

The EMPr already covers the conservation of heritage and palaeontological material that may be exposed during construction/prospecting activities. For a chance fossil find, the protocol is to cease all construction activities, construct a 30 m no-go barrier, and contact SAHRA for further investigation. It is recommended that the EMPr be updated to include the involvement of a palaeontologist when necessary.

The palaeontological impact assessment process presents an opportunity for identification, access and possibly salvage of fossils and add to the few good localities. Mitigation can provide valuable onsite research that can benefit both the community and the palaeontological fraternity. A Phase 2 study is very often the last opportunity we will ever have to record the fossil heritage within the development area. Fossils excavated will be stored at a National Repository.
