Aspect: Materials

EN1 (Core)Materials used by weight or volume.Global Compact ICMM principle

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.

EN2 (Core)Percentage of materials used that are recycled input materials.Global Compact

Due to the nature of the mining industry, mining companies predominantly use chemicals and raw materials to produce their commodities. As such, there is limited opportunity to substitute for recycled input material on a significant scale. Therefore, recycled input material use by the group is not significant, and consequently measuring it is not deemed meaningful.

Aspect: Energy

EN3 (Core)Direct energy consumption by primary source. Global Compact ICMM principle

During 2009, a total of 0.59 million GJ of hydro-electrical power was generated at AngloGold Ashanti operations; 0.44 million GJ at the Brasil Mineração operations in Brazil and 0.15 million GJ at the Mponeng operation in South Africa. This compares to a total of 0.62 million GJ of hydro-electrical generation in 2008, 0.49 million GJ at the Brasil Mineração operations and 0.14 million GJ at Mponeng.

Our primary product is gold, which is chemically inert. Gold is used as a store of financial value by banks and investors, in the manufacture of jewellery and in several industrial applications. It is infinitely recyclable. It has little to no direct impacts. However, there are impacts related to the production of gold. To mitigate and manage these impacts, we maintain a group environmental policy which is given effect through site-based environmental management systems that are certified to the ISO14001 standard.

MM3Biodiversity management plans 

AngloGold Ashanti is developing a biodiversity standard which will be finalised during 2010. It is based on ICMM's Good Practice Guidance on Biodiversity, and has been subjected to internal and external peer review. The company does not currently require the development of stand-alone biodiversity management plans but rather requires that biodiversity is considered as part of the ISO14001 process, with the site’s significant environmental aspects being identified and management plans developed to address these. Through this process, the need for Biodiversity Actions Plans is determined locally and includes both regulatory and Interested and Affected Parties’ requirements in their content.

MM4Production from secondary materialICMM principle

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, 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.

MM5Product eco-efficiency attributes 

AngloGold Ashanti mines, smelts and refines gold. It also produces silver and uranium as by-products. Metals are infinitely recyclable. The company’s Environment and Community Policy, revised in 2009, is the overarching statement that directs gold production processes in enhancing eco-efficiency by maximising natural resource use efficiency, such as land, water and energy, optimising recycling opportunities, preventing pollution and seeking less toxic consumables through ’green procurement’ initiatives. This policy is given effect through site environmental management systems, which are externally certified to the ISO14001 standard.

MM6Management approach for waste and residues storage facilitiesICMM principle

Various waste 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 waste 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 license requirements for these various facilities, for example stability assessments, water quality 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).
