It includes justification for undertaking the project based on its anticipated risks, expected benefits and estimated costs. Business cases are used to assist in decision making processes, obtain management commitment and gain investment approval by providing sound rationale for the investment. A business case should address all phases of a project including closure; to do otherwise risks making a poor project investment. The need for mine closure to be an integrated part of the complete project life cycle, including business planning, is well documented. However, the information required by mining companies and project managers, and the tools that can be used to develop the business case for closure, are less well understood. Consequently, many industry personnel experience difficulty in developing an effective business case for closure. To provide guidance on how to successfully integrate mine closure planning and valuation into the business planning process, this paper draws on experience in the mining industry in Australia and Asia from the perspective of mining companies. This paper does not attempt to list all of the requirements for building a successful business case for closure, but discusses six key aspects in this regard: motivation, project design, risk assessment, legal compliance, closure valuation and teaming.
