A retention lease is granted for a lease term not exceeding 5 years and in accordance with one (or more) of the purposes set out in section 41A of the Mining Act. A retention lease will usually be granted with the requirement for a specific program of work to be undertaken.
Retention lease PEPR reviews can be initiated by the tenement holder or directed by the Minister for Energy and Mining (which may be given at any time for any reasonable cause) in accordance with section 70C of the Mining Act.
Should you wish to undertake mining operations that are not described in your current approved PEPR, then these will need to be authorised through a PEPR review (subject to compliance with the lease terms and conditions).
Should you wish to change or alter the description of mining operations in an approved PEPR, this may require a PEPR review depending on the significance of the change.
Changes or alteration to mining operations that will affect the achievement of environmental outcomes, or require new or modified outcomes, measurement criteria or leading indicator criteria will require a PEPR review.
