This discussion paper is about the social aspects of mine closure. We focus on a set of questions relating to transformations at the end of mine life, namely: - What happens when major mining projects come to the end of their economic life? - How are responsibilities for end of life planned and distributed among stakeholders? - What does industrial transformation mean, for different stakeholders, at closure? This paper aims to generate constructive discussion about the social dimensions of mine closure. We do not offer direction, a series of checklists, or a "how-to" guide. Our intent is to prompt deeper thinking about the social dimensions of mine closure. We encourage the industry to use this document to initiate and facilitate conversations about its own future, and the future of the communities in which it operates.
