Pantheon Resources plc

Appearance at Alaska Legislature Special Session and Operational Update

Pantheon Resources plc ("Pantheon" or the "Company"), the oil and gas company developing the Kodiak and Ahpun projects on Alaska's North Slope, is pleased to report that it was asked to join other North Slope producers before the Alaska Legislature's House Finance Committee ("the Committee") late last week, to provide an overview of the Company's projects and their potential to provide natural gas to the proposed natural gas pipeline being pursued by The Glenfarne Group and the State of Alaska (the "AK LNG Project").

The Legislature is currently in a Special Session focused exclusively on a tax relief package sponsored by the Governor to support the AK LNG Project. The Company joined ExxonMobil, ConocoPhillips, and Hilcorp as invited testimony from the proposed gas suppliers to the AK LNG Project.

Pantheon's session before the Committee included a discussion of the gas supply potential of its Kodiak and Ahpun projects, the advantageous low CO2 composition of its gas and the Company's ability and willingness to offer its gas at a relatively low price to improve the economics behind the AK LNG Project, particularly Phase 1 of the project which is intended to provide those in Southcentral Alaska with a reliable supply of natural gas at the lowest cost possible as they are facing a looming energy supply shortage.

A copy of the presentation can be found in the 'Presentations' section of the Company website. A recording of the session can be accessed through the following hyperlink

Operational Update

Pantheon continues to actively pursue all available strategic options to maximise value from its projects and confirms that the farm-out initiatives remain underway, with multiple parties engaged in the data room. As previously reported, such discussions are complex by nature, requiring extensive due diligence, and as such, a rapid outcome should not be expected, however progress is being made and the Company anticipates providing an update to the market before the end of summer.
