Notes to Editors

Pantheon Resources plc is an AIM listed Oil & Gas company focused on several large projects located on the North Slope of Alaska ("ANS"), onshore USA where it has a 100% working interest in 153,000 highly prospective acres with potential for multi billion barrels of oil recoverable. A major differentiator to other ANS projects is its close proximity to transport and pipeline infrastructure which offers a significant competitive advantage to Pantheon, allowing for materially lower capital costs and much quicker development times. The Group's stated objective is to create material value for its stakeholders through oil exploration, appraisal and development activities in high impact, highly prospective conventional assets, in the USA; a highly established region for energy production with infrastructure, skilled personnel and low sovereign risk. All operations are onshore USA, with drilling costs materially below that of offshore wells.
