Walton Morant Licence - Grant of Beach Licence

United Oil & Gas Plc (AIM: "UOG"), the oil and gas company with a high-impact exploration asset in Jamaica and a development asset in the UK, is pleased to announce that it has been Granted the Beach licence. This licence enables United to undertake seabed sampling operations within the Walton Morant Basin, offshore Jamaica

This milestone builds on the recent extension of the Walton Morant Licence to January 2028 and the granting of the Environmental Permit, announced on 24 July 2025, marking continued progress in United's permitting for the work program for the Jamaican licence.

The Beach Licence is a continuous licence and renews annually on the 1^st April and authorises United to conduct a piston core survey in the foreshore and seabed areas and to collect seabed samples for geochemical analysis, an essential step in assessing hydrocarbon potential. These surveys will enhance United's technical dataset and are specifically designed to de-risk the licence by providing critical information to support prospectivity, including potential hydrocarbon indicators in the seabed. The sampling programme will support ongoing technical workstreams to further de-risk the licence.

Brian Larkin, CEO of United Oil & Gas, commented:

"The granting of the Beach Licence marks another important step forward in our efforts to unlock the potential of the Walton Morant Basin. Seabed sampling will provide valuable geochemical insights that support our technical evaluation and further enhance the prospectivity and value potential of the Walton Morant licence area. With parties engaged in the data room, this progress helps make the asset even more attractive to potential farm-in partners We are grateful to the Jamaican authorities for their continued support and look forward to advancing our work programme in the region."
