Mining has played a significant role in human development and without the mining sector, society would not enjoy a large number of the benefits that it does today. However, mining has also carried with it some important lessons, which remain the source of ongoing learning. One of these lessons is the poor closure or abandonment of mines, worldwide. This has in many cases resulted in large tracts of unproductive land, representing a source of environmental pollution and a safety hazard to the community. Frequently associated with this is a legacy of mining communities having fallen into economic and social decline, beyond mine closure.Due to this legacy, governments, society and the mining sector pay far greater attention to mine closure planning today, than was done in the past. Typically closure planning has focused on the engineering aspects of a mine, namely decommissioning of the workings and plant; dismantling of unusable infrastructure; and rehabilitation of disturbed land. These are important aspects of closure but a more holistic, long-term approach is required which encompasses environmental and social aspects and aims to leave a positive legacy behind.In planning for a mine closure scenario with a lasting positive legacy, it is critical that the broader receiving environments (social, economic, physical and biological) within which a mine is located, define and drive the closure plan and the mine planning as a whole. This ensures that the broader environment influences mine closure, as opposed to looking at how a closed mine will impact on the environment. The ultimate aim is to first understand the broader environment and then to fit the closure of a mine into it. The earlier this approach is followed in the life of a mine, the greater the operational time frame available, and hence a better chance is presented for planning and managing a mine towards the desired, tested and agreed post closure scenario. Within this broad context, there is tremendous scope to achieve successful mine closure. However, it is critical to note that mine closure is not the sole responsibility of the mining companies, and neither is it possible for said mining companies to achieve mining closure alone. This concerted effort requires a multi-stakeholder approach in which partnerships are created and risks, responsibilities and opportunities are shared and managed. To achieve sustainable closure, a multi-stakeholder approach based on an initial forward-looking closure vision is required. This approach provides an early basis for consideration of alternative land uses and economic options from which specific actions to achieve the preferred option can be defined. The Anglo American plc Mine Closure Toolbox has been formulated and developed around this concept. The Toolbox aims to expand mine closure planning - from financial provisioning for rehabilitation and physical closure, to planning for sustainability beyond mine closure and leaving behind a positive legacy.This paper focuses on the business case for mine closure planning and provides an overview of the Anglo American plc (AAplc) Mine Closure Toolbox.CITATION:Botha, P R, 2012.
