Pantheon Resources plc advise that it has received an Independent Expert Report ("IER") which provides an estimate of contingent resources recoverable from its 100% Working Interest Kodiak project, formerly known as Theta West ("Kodiak"). A full copy of the report will be published on the Company's website. The 2C estimates (best estimates) of oil and natural gas liquids ("NGLs") total 962.5 million barrels of marketable liquids.

As previously advised by management, the NGLs on Pantheon's projects are of material value as they can be blended with the oil and the combined stream of oil, condensate and NGLs has been estimated by management to yield approximately 90% of the value of the Alaska North Slope ("ANS") price per barrel. The management believe the Kodiak NSAI IER supports the Company's development plans for the Kodiak project, which will involve development of leases totaling some 126,000 acres (including the recently awarded additional acreage), delineated by the Company's proprietary 3D seismic and confirmed by three wells (Pipeline State 1, Talitha-A and Theta West-1). The field is defined as the hydrocarbon bearing horizons contained within the large basin floor fan between the Hue Shale top seal and the underlying HRZ shale, from their downdip pinchout east of Talitha-A running to over 15 miles northwest into the new "chimney acreage" acquired in the 2022 area wide lease sale.

The Company believes that this is one of the largest basin floor fan systems discovered onshore in the past few decades. he absence of wireline electric logs or sidewall cores taken at Theta West-1, due to hole stability issues and the limited time available at the end of the drilling season, has meant that the highest resolution data that captures the thinly interbedded reservoir in the Kodiak field is limited to the Talitha-A well. The Company plans to drill the next Kodiak well significantly updip from the Talitha-A and the Theta West-1 wells, where management believe the lower depth of burial ("Dmax") should lead to improved reservoir characteristics compared to both Talitha-A and Theta West-1. The Company has completed a detailed geological model taking into account data from wells in the immediate area which include the producing Tarn and Meltwater fields.

Pantheon plans to drill the next Kodiak appraisal well in the recently acquired leases, some five miles northwest of Theta West-1. Based on the Company's petrophysical analysis noted above, a Theta West-2 well in that location would be expected by management to encounter a reservoir section with 37% of the pay interval exhibiting porosities at or above 12% and permeabilities of greater than 0.1 milliDarcies - the typical cut-off for recognising reservoirs as conventional, which typically yield higher flow rates and hydrocarbon recovery rates. The reservoirs in the structural updip portion on the Theta West structure are expected by management to exhibit the highest quality on Pantheon's acreage, in its largest trapping mechanism. The Company plans to cut full cores and acquire a full suite of wireline logs and representative fluid samples/flow tests in future appraisal wells to address the contingencies in NSAI's evaluation.

Demonstrating the character of the reservoir at the most granular possible level creates potential for future increases to recoverable resource estimates. the company confirm that the All-American Oil Rig 111 has been formally contracted forthe re-entry of the Alkaid-2 well to test the SMD horizon. Pantheon has also awarded all major service provider contracts necessary for the operation.

Finalisationof necessary permits forthe operation is ongoing, with mobilisation of the rig targeted for September.
