Thinking about the end before you start - Integrating mine closure planning into feasibility studies and environmental and social impact assessments

For many projects, a mine closure plan is prepared when required for the site's environmental and social impact assessment process. All too frequently, this is the first time that closure requirements have been considered in the planning process. Mine closure planning conducted during impact assessment tends to focus on the development of high-level closure objectives and strategies, but provides little information on how these will be implemented, and generally does not include a closure cost estimate. Consequently, there is little certainty about whether the proposed closure plan can be implemented effectively, and the stated outcomes can be achieved. The challenge for mine closure planning during feasibility studies and impact assessments is to provide sufficient certainty for proponents, regulators, shareholders and other stakeholders at a stage in the project life that is often characterised by degrees of uncertainty. This paper discusses key considerations and presents suggestions for integration of mine closure planning into feasibility studies and environmental and social assessments.
