1 Annual Reports 2011 / Sustainability Report / Supplementary information / Materials and EN1 The information below provides disclosure under the Global Reporting Initiative (GRI) indicator EN1: Materials used by weight or volume Input materials The primary raw materials used by the group include the ore processed during the extraction and recovery of gold from its host rock (direct raw materials). Primary process materials used include non-renewable materials such as liquid fossil fuels, lubricants and solid fossil fuels and renewable materials such as cyanide, explosives, acids and alkalis. These bulk materials are used or consumed during gold processing and are relevant to environmental management in that these must be controlled by the operations to avoid environmental impacts. Cyanide is managed under the guidelines provided by the International Cyanide Management Code.

Recycled input materials As a gold mining company, AngloGold Ashanti produces gold, either as a bullion (typically 80-95% gold) or refined (99.5+%) bars, as well as silver and uranium as by-products. These are, by definition, original metal. Owing to the nature of mining, companies use manufactured products, such as steel, fossil fuels, chemicals and explosives, and natural resources, such as water, timber and mined rock, as well as electricity, to produce their commodities. There is therefore limited opportunity to substitute recycled or secondary materials on a meaningful scale, except where suppliers have already incorporated recycled materials into the product, for example, recycled steel into piping, liners and steel balls. Consequently, measuring the extent of use of recycled input materials is not deemed meaningful.

Various materials are produced during the mining cycle. Internal Tailings and Heap Leach Management Frameworks set the standard as well as provide guidance to which tailings and heap leach facilities must be constructed and operated. Internal geotechnical engineers are responsible for ensuring the structural stability of tailings, heap leach facilities and rock dumps. During the design phase, appropriate handling and placement considerations have to be factored into the project design to ensure satisfactory protection of the environment and the safety of neighbouring communities. Risk assessments, environmental impact assessments, stakeholder engagement processes and other studies are used to identify appropriate mitigation measures and controls. During the operational phase, monitoring and audit processes are used to establish trends, identify emerging issues and to ensure conformance to the defined standard operating procedures and operating licence requirements for these various facilities, for example stability assessments, water quality and dust monitoring, hydrogeological and geochemical modelling etc., are carried out to monitor the effectiveness of the design and controls. Closure considerations are generally defined at the design phase, continually revised throughout and finalised during the operational phase. These controls are then implemented during the closure phase (with appropriate post-closure monitoring). AngloGold Ashanti Annual Reports 2011
