This revised handbook addresses mine closure, one of the themes in the Leading Practice Sustainable Development (LPSD) Program. The program aims to identify key issues affecting sustainable development in the mining industry and provide information and case studies that illustrate a sustainable basis for the industry. A number of other themed handbooks in the series complement this handbook. The leading practice handbooks integrate all phases of mineral production, from exploration to post-closure and relinquishment.The mining industry is embracing the concept that completion and relinquishment incorporate delivery of a defined post-mining land use rather than just closure when the operational stage of a mine ceases and decommissioning is complete. To assist in planning for this, a new phase in the life of mine (LoM), termed ‘post-closure management’ (Section 3.7) has been added to this handbook to accommodate longer term considerations for companies to manage post-decommissioning conditions en route to relinquishment.
