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 that the NSW Government does not incur financial liabilities in the event of a title holder defaulting on their rehabilitation obligations. Further details are provided in our policy ESP1: Rehabilitation security deposits and ESG1: Rehabilitation cost estimate guidelines.

The title holder is required to provide an estimate of rehabilitation costs for consideration by the Regulator when determining the security deposit amount. The amount must be consistent with the stage of the exploration project or mine. A Rehabilitation cost estimation tool and Rehabilitation cost estimation tool handbook is available to assist in calculating the security deposit for a site.

Our inspectors regularly assess the surface disturbance (or proposed disturbance) of a mine or exploration site to calculate the security deposit. This is known as the assessed deposit. Once the assessed deposit is determined, we advise the Mining, Exploration and Geoscience (part of Regional NSW), who vary the condition of the title and seek the additional funds - or in the case of satisfactory rehabilitation, returns some or all of the security deposit. Click below to view the list of assessed deposits determined by the Regulator as at 28 July 2020.
