Wressle Planning Update PEDL180/PEDL182

Union Jack Oil plc (AIM: UJO, OTCQB: UJOGF), a UK and USA focused onshore hydrocarbon, production, development, exploration and investment company, confirms that, as expected and indicated in the announcement dated 18 October 2024, planning permission for the Wressle development, initially granted on 13 September 2024, has been formally rescinded. This is on the basis that the North Lincolnshire Council ("NLC") omitted to consider the likely Scope 3 GHG (greenhouse gas) emissions associated with the project when determining if the proposed development required an Environmental Impact Assessment ("EIA"). This is a consequence of the Supreme Court Finch ruling in June 2024, which post-dated the original EIA screening decision by the NLC made in July 2023.

The Operator, Egdon Resources U.K. Limited, will now provide the NLC with an analysis of Scope 3 GHG emissions for the proposed development conducted by an independent third-party specialist company and request a new EIA screening opinion. Depending on the outcome of this decision, a new determination of the Wressle planning application will be made based on either the existing submitted information or with the requirement for a new Environmental Statement.

This decision has no effect on the existing planning consent at Wressle and production and operations continue with no detriment to Union Jack and its partners.

The Company holds a 40% interest in the Wressle development.
