6 Conclusions The objective of this bulletin is to facilitate access to the relevant existing information by Group companies. The aspects and critical areas above have been highlighted as areas where past experience has indicated certain operations to have been lacking. Anglo American Technical Division would welcome all comment from any of the Group's operating companies which will be considered in an attempt to improve the document by incorporate the operating experiences within the Group. 7 Acknowledgements In the preparation of this bulletin significant guidance has been obtained from the AngloGold Ashanti Tailings Management Framework, and from personal communication with the companies' staff. This assistance is gratefully acknowledged. The current ICMM committee and working group activities involved in the preparation of the ICMM Tailings Reference Guidelines has also been a significant help and the ICMM is thanked for the opportunity given to Anglo American to partake in those activities. 8 References 1.

Appendix A Overview of Existing Regulations and Guidance Procedures for Tailings Management from Mining Jurisdictions around the World As a forerunner to the ICMM international guideline initiative mentioned above, a survey was done on the status of existing international guidelines by Golders in October 2000 (Reference 7.1). One of the outcomes was an overview of the regulating and guidance procedures around the world described below, and an extract from their report is included in this Appendix below. a) Guides and Manuals There are only four guides or manuals available internationally that are truly management guides in the sense that they provide an overall approach or framework for the management of tailings facilities: South Africa South African Bureau of Standards “Code of Practice for mine Residue Deposits”, 1998 (SABS 0286:1998 renamed SANS 10286). This gives a consolidated view of the industry and regulators and sets out minimum requirements and requires that a management system be put in place. The management system must be audited and the frequency of audit depends on the hazard rating of the facility. For ease of reference as many of the Group’s companies operate in South Africa, the contents pages are included in this bulletin as Appendix C. Tailings management in South Africa is regulated by law in the guideline for a mandatory code of practice issued by the Department of Minerals and Energy in 2000 (Reference 3). This guideline makes implementation of a code of practice mandatory for each tailings facility with compulsory adherence to the SANS Specification 2086. Western Australia Department of Minerals and Energy, Western Australian Government “Guidelines for the Safe Design and Operating Standards for Tailings Storage” May 1998. This is prescriptive in nature and addresses conditions in Western Australia. It has both technical and management aspects. Types of tailings are described, risk assessment is addressed, administrative procedures are provided and there are check lists. Canada The Mining Association of Canada (MAC) “A guide to the Management of Tailings Facilities” 1998. This provides a guide for self-management and assists mine management in demonstrating due diligence, complementing government regulations and meeting higher environmental standards. Though it has technical references it is not a technical guide. Peru Ministero de Energia y Minas, Republica de Peru “Guija de Manejo de Relaves de Minas y Concentrados” October 1997. This is primarily a technical guide addressing causes of failure. b) Other Guides In addition to the above, there are three other guides with some management guidance but they are more technical or specific in nature: Australia Australian EPA “Best Practice Environmental Management in Mining – Tailings Containment” 1995. This provides an overview and presents a management framework and case studies. Issued by the Anglo Technical Division page 13 of 47
