Receipt of Environmental Permit - Walton Morant Licence, Jamaica

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 confirm formal receipt of the Environmental Permit from Jamaica's National Environment and Planning Agency ("NEPA") for UOG's planned offshore surveys at its 100% owned Walton Morant Licence.

This follows the Company's 30 June 2025 announcement, confirming that the approved permit had been listed on NEPA's website. The permit is now in hand and is valid for five years.

The Environmental Permit encompasses a range of non-invasive offshore surveys, including bathymetric, geotechnical, and environmental baseline studies. It represents a key milestone in progressing toward the next phase of operational activities under the licence. A final outstanding permit, known as a Beach Licence, is expected shortly and will complete all approvals required before any operational activities can commence.

These surveys will further enhance United's technical dataset and are designed to further de-risk the licence by providing critical data to support prospectivity, including potential hydrocarbon presence in the seabed. While not required for the farmout, they will support ongoing technical workstreams, underpinned by the recent licence extension to January 2028.

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

"With the Environmental Permit now secured and the Beach Licence expected shortly, we are moving into a position to advance technical operations and rebuild momentum across one of the most exciting and underexplored basins in the region.

The Walton Morant licence presents a compelling opportunity, with billion-barrel-scale potential, drill-ready targets, and a source rock interval of similar age to that found in the prolific basins of Guyana,Trinidad & Tobago, and elsewhere in the Caribbean region.

Encouraging industry interest continues, and advancing the farmout remains a core strategic priority. The farmout process is progressing in parallel to survey preparations and is not contingent upon them. Our focus is on unlocking value through both technical de-risking and commercial engagement."
