What do you really need to know about mine closure planning and costing?

This high level talk covers key aspects of mine closure planning and costing from both international and local perspectives (using specific examples from Queensland). It will address the importance of focusing on closure as part of corporate due diligence, and will also look at assessing risk and the impact of inadequate closure planning and costing for corporate and financial assurance.
