Social, Environmental and Health Legacy Issues
MATERIAL ISSUE 4: The Nykabale village nursery is a project sponsored by AngloGold Ashanti to supply trees to the community and Geita Gold Mine, Tanzania. © 2014 ANGLOGOLD ASHANTI | ANNUAL REPORTS 2013 | Disclaimer MATERIAL ISSUE 4: Lung function testing at the occupational health clinic at Obuasi, Ghana. Context Occupational health and safety Occupational lung disease (OLD) is a risk inherent in many underground gold mines where silica dust is present. The most significant forms of OLD seen within the company are silicosis and pulmonary tuberculosis (TB). OLD in Brazil has virtually been eradicated, as a consequence of mechanisation of mining, improved ventilation, dust suppression, personal preventative measures and statutory limitations on the length of service of underground employees. If inhaled, silica dust may cause inflammation and scarring in the lungs, resulting in impaired lung functioning. Silicosis typically has a long latency period of more than 15 years and is sometimes only detected years after exposure. Silicosis in South Africa is a legacy issue on which AngloGold Ashanti and the gold mining industry as a whole, as well as government, unions and health care professionals place an enormous effort in addressing. Our occupational health strategy encompasses both minimising current risks, primarily by reducing occupational exposure within the industry. In 2008, we committed to eliminating new cases of silicosis among previously unexposed employees at our South African operations. Pulmonary TB, particularly where it is associated with silica dust exposure, is a key area of concern. Our immediate commitment is to reduce occupational TB incidence to below 2.25% among our South African employees and to successfully cure 85% of new cases – a target set by World Health Organization (WHO). -
Modelling the Optimum Interface Between Open Pit and Underground Mining for Gold Mines
MODELLING THE OPTIMUM INTERFACE BETWEEN OPEN PIT AND UNDERGROUND MINING FOR GOLD MINES Seth Opoku A thesis submitted to the Faculty of Engineering and the Built Environment, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy. Johannesburg 2013 DECLARATION I declare that this thesis is my own unaided work. Where use was made of the work of others, it was duly acknowledged. It is being submitted for the Degree of Doctor of Philosophy in the University of the Witwatersrand, Johannesburg. It has not been submitted before in any form for any degree or examination at any other university. Signed …………………………….. (Seth Opoku) This……………….day of……………..………2013 i ABSTRACT The open pit to underground transition problem involves the decision of when, how and at what depth to transition from open pit (OP) to underground (UG). However, the current criteria guiding the process of the OP – UG transition are not well defined and documented as most mines rely on their project feasibility teams’ experiences. In addition, the methodologies used to address this problem have been based on deterministic approaches. The deterministic approaches cannot address the practicalities that mining companies face during decision-making, such as uncertainties in the geological models and optimisation parameters, thus rendering deterministic solutions inadequate. In order to address these shortcomings, this research reviewed the OP – UG transition problem from a stochastic or probabilistic perspective. To address the uncertainties in the geological models, simulated models were generated and used. In this study, transition indicators used for the OP - UG transition were Net Present Value (NPV), ratio of price to cost per ounce of gold, stripping ratio, processed ounces and average grade at the run of mine pad. -

Reef Adjacent to Structures at Tautona Mine, Anglogold Ashanti South African Operations
Reef Adjacent To Structures at TauTona Mine, AngloGold Ashanti South African Operations DE DAVIES Section Manager TauTona Mine, AngloGold Ashanti South African Operations SYNOPSIS The paper describes the extraction of reef adjacent to geological structures in the Carbon Leader Reef Section at TauTona Mine. Traditionally long wall mining has left feasible and economical blocks of ground adjacent to structures when negotiating major geological features. This meant that mining through an up- throw fault, rolling to the reef elevation on the displaced side of the fault left reef in the long wall. High grade areas were abandoned and gold was sterilized. In these tight economic times and with the need to continuously improve safety standards the need arose to develop a technique to extract these blocks economically and safely. It was believed that the structures in these abandoned areas were de-stressed and could now be mined in small volumes at a high grade. The term RATS is an acronym derived from “reef adjacent to structures” and aptly describes the process of identifying and extracting these blocks. The viability of this method was addressed in terms of the mine design, underground investigations and financial risks. The paper concludes with an analysis of the successes achieved to date. 1 INTRODUCTION TauTona Mine is one of the AngloGold Ashanti Southern Africa operations. It is close to the town of Carletonville in the province of Gauteng and about 70km south-west of Johannesburg. TauTona is 46 years old and employs ± 4 000 people. Mining operations are conducted at depths ranging from 1,800m to 3,500m at which the world’s deepest stoping sections are found. -

Access Ways in Ultra High Stress – the Next Step SANIRE 2004 – the Miner’S Guide Through the Earth’S Crust, South African National Institute of Rock Engineering
Scheepers, L.J, Stability of access ways in ultra high stress – The next step SANIRE 2004 – The Miner’s Guide through the Earth’s Crust, South African National Institute of Rock Engineering Stability of access ways in ultra high stress – The next step L.J. Scheepers TauTona Mine ABSTRACT Stability of access tunnels through high stressed abutments remains a problem associated with deep level mining. The problem is compounded by the presence of faults or dykes in these abutments or pillars as large seismic events can occur on such features. This paper describes a novel way of ensuring the long-term stability of access tunnels through high stressed areas by mining an off reef de-stressing slot 7m above the tunnel simultaneous with and leading the development of the tunnel. 1 Introduction Republic of South Africa. Figure 1 shows the location of TauTona Mine in the West Rand Area. With all mining operations the stability of the access ways to the ore bodies are crucial for sustained safe Two economically viable gold-bearing orebodies are production. In deep level operations, quasi-static exploited within the TauTona Mine boundary area, stress related instabilities must be catered for with namely the younger and shallower Ventersdorp layout and support design of the access ways. In Contact Reef (VCR), and the older, deeper Carbon addition possible seismic loading on the access ways Leader Reef (CLR). must also be catered for. This is certainly true for TauTona Mine. At TauTona the CLR has been accessed and mined from depths between 2500 and 3600 metres below surface for an area of approximately 5000m on strike by 3500m on dip within the lease area.
