Notes to Editors

Pantheon Resources plc is an AIM listed Oil & Gas company focused on developing the Ahpun and Kodiak fields located on state land on the Alaska North Slope ("ANS"), onshore USA, where it has a 100% working interest in c. 193,000 acres. In December 2023, Pantheon was the successful bidder for an additional 66,240 acres with very significant resource potential, contiguous to the Ahpun and Kodiak projects. Following the issue of the new leases, which are expected to be formally awarded in summer 2024 upon payment of the balance of the application monies, the Company will have a 100% working interest in c. 259,000 acres. Certified contingent resources attributable to these projects exceeds 1 billion barrels of marketable liquids, located adjacent to Alaska's Trans Alaska Pipeline System ("TAPS").

Pantheon's stated objective is to demonstrate sustainable market recognition of a value of $5-$10/bbl of recoverable resources by end 2028. This will require targeting Final Investment Decision ("FID") on the Ahpun field by the end of 2025, building production to 20,000 barrels per day of marketable liquids into the TAPS main oil line, and applying the resultant cashflows to support the FID on the Kodiak field by the end of 2028.

A major differentiator to other ANS projects is the close proximity to existing roads and pipelines which offers a significant competitive advantage to Pantheon, allowing for materially lower infrastructure costs and the ability to support the development with a significantly lower pre-cashflow funding requirement than is typical in Alaska.

The Company's project portfolio has been endorsed by world renowned experts. Netherland, Sewell & Associates ("NSAI") estimate a 2C contingent recoverable resource in the Kodiak project that total 962.5 million barrels of marketable liquids and 4,465 billion cubic feet of natural gas. NSAI is currently working on estimates for the Ahpun Field.
