An assessment lease is designed to cater for situations between exploration and mining. The lease allows the holder to maintain an authority over a potential project area, without having to commit to further exploration. The holder can, however, continue exploration to further assess the viability of commercial mining.

The Resources Regulator has developed a new online version of the Statement of compliance, environmental performance and financial history form. All relevant Mining Act 1992 application forms link to the online version of this form. For a word version of the Statement of compliance, environmental performance and financial history, please refer to the Resources Regulator website at https://www.resourcesregulator.nsw.gov.au/environment/forms. For any further information about this form, please contact the Resources Regulator on 1300 814 609.
