Can mining promote sustainable development? What is sustainable development? Is sustainable development good for corporate sustainability? Does it work in practice? If so, is it good for business? This paper does not seek to provide definitive answers to these issues. Rather, it is presented in the interests of sharing information and contributing to the pool of collective experience. The discussion will draw on the experience of Placer Dome in Papua New Guinea (PNG). Sustainable development means development that is maintained at a steady level without exhausting natural resources or causing ecological disturbance. The term sustainable development' is often linked to the concept of ecological equilibrium, development that is self-replenishing. While its essential meaning remains the same, in practice, and for today's complex and industrial world, different people will interpret sustainable development in different ways. Given the dynamics of development and the competing social, political and economic interests, sustainable development must be seen from a much broader perspective. This is the point that this paper will attempt to make. Mining, an activity that uses non-renewable resources, can promote sustainable development. The 1987 Brundtland Report (also known as the Report of the World Commission on Environment and Development), defines sustainable development in a broader manner - as development that meets the needs of the present world without compromising the ability of future generations to meet their own needs (Elkington, 1997). This definition calls for inter-generational equity in the development and use of resources by many organisations, including multinational corporations. Corporate sustainability, on the other hand, is about developing strategies that guide a corporation to stay alive and, more importantly, to stay ahead of its competitors. It is basically about survival in a competitive social and commercial environment. In a corporate world, profitability is survival. In this context, corporate profitability, the main ingredient of corporate sustainability, is important for sustainable development. Without profits, corporations will find it difficult to practice sustainable development or indeed any development. Sustainable development can integrate mining activities with the rest of the community, add value and, in the long-term, profits to the bottom-line. Ultimately, sustainability will force corporations to adopt strategies based on a longer time scale to survive. In the mining sector, corporate sustainability depends on a close relationship with all stakeholders, particularly landowners for whom sustainable development is critically important. Increasingly, there is an acceptance of the view that success is not achieved simply through competition in price, cost and technology but, more importantly, through creating social infrastructure which support community ethics, norms and values essential for trust and partnership. Needless to say, mining companies that engage in appropriate community-based development in support of inter-generational justice recognise the true value of sustainability. This is sometimes called the human sustainability approach' which underlines the critical significance of trust in relationships with stakeholders and continuous improvement of corporate capabilities directed towards the future (Dunphy and Griffiths, 1998). In the long-term, such development will enhance corporate public image and acceptability. In practice, both concepts can be built on the principles of economic viability, environmental quality and social justice -what, in today's parlance, is increasingly becoming known as the triple-bottom-line' approach to business (Elkington, 1997). Underpinning this approach is a process of continuing dialogue and co-operation between governments, non-government organisations (NGOs) and business.
