Mining securities

All mining activities authorised (licenced) under the Mining Management Act 2001 are required to lodge a security with the Department of Industry, Tourism and Trade.

The purpose of the security is for the payment of costs if action needs to be taken by the government to prevent, minimise or rectify environmental harm caused by mining activities on or off the mining site or for completion of rehabilitation.

The amount of security is based on the amount of disturbance likely to be caused by the mining activities carried out under the authorisation, subject to the approved mining management plan.
