Reserves and contingent resources

The reserves and contingent resources for the Mereenie, Palm Valley and Dingo fields (where applicable) above are as at 31 December 2021 and were first reported to ASX on 3 March 2022.

The Mereenie contingent gas resources include 27 PJ attributable to the Mereenie Stairway formation.

The contingent resources for the Range Gas Project were first reported to ASX on 21 August 2019.

The total aggregated reported 1P reserves may be a very conservative estimate and the aggregate 3P may be a very optimistic estimate due to the portfolio effects of arithmetic summation.

Central confirms that it is not aware of any new information or data that materially affects the information included in those announcements and all material assumptions and technical parameters underpinning the estimate continue to apply and have not materially changed.
