Information about this report

The estimates of reserves shown in this report were prepared in accordance with the definitions and guidelines set out in the 2007 Petroleum Resources Management System approved by the Society of Petroleum Engineers.

The reserves associated with AGL’s 100% owned and operated Hunter Gas Project were estimated by SRK Consulting (SRK). SRK is an independent international consulting practice that has been operating since 1974 and currently employs over 900 professionals worldwide. Staff from SRK's Brisbane office worked closely with AGL staff to validate detailed resource databases that formed the basis for 3D geological models. Evidence of commercial production flows in combination with these models formed the basis for the reserve estimates.
