New Trends in Managing Mining Liability

Michael Cramer

Director, Accent Environmental


Example trends being considered or actively implemented by mining regulators in Australia are:

  • Financial provisioning for residual (post-relinquishment) site management
  • Greater emphasis on and scrutiny of mine closure plans
  • Requirements to meet agreed progressive rehabilitation goals
  • The use of pooled funds (such as in WA) to cover rehabilitation liabilities (or components of those liabilities)
  • Increasing pressure on proponents/regulators to ensure financial assurance more closely matches liability, as it is generally accepted that it currently does not
  • Updating of rehabilitation liability calculation tools and the potential inclusion of risk-based cost factors in liability calculation.

As the risk profile of quarrying operations is different from many mining operations, the risk to the quarrying industry is that they get swept up in these trends/reforms without due consideration of their specific circumstances.
