Security deposits

It is the responsibility of the NSW Resources Regulator to ensure that land disturbed by exploration and mining activities is returned to a safe, stable and sustainable land use.

All exploration and mining title holders are required to lodge a security deposit with the department that covers the full rehabilitation costs. This requirement ensures the NSW Government does not incur financial liabilities in the event of a title holder defaulting on their rehabilitation obligations.

Title holders are required to provide an estimate of rehabilitation costs for our consideration when determining the security deposit amount. The estimate must be:

A Rehabilitation cost estimation tool and handbook are available on our Guidance material for mining page.

Our inspectors regularly assess the surface disturbance (or proposed disturbance) of a mine or exploration site to calculate the initial security deposit. This is known as the assessed deposit. Once the assessed deposit is determined, we will vary the condition of the title and ensure the correct funds are held. 

Over the life of the mine or exploration project, we regularly assess security deposits to ensure sufficient funds are held. When rehabilitation is completed and signed off, some or all of the security deposit is returned to the title holder.
