88 Energy Limited ("88 Energy" or the "Company", ASX:88E, AIM:88E, OTC:EEENF) is pleased to provide the following update related to its operations on the North Slope of Alaska.
· Testing commenced on sidewall cores, cuttings, mud gas and fluid samples from Merlin-1
o Results expected over next 2 - 10 weeks
· Initial mapping of additional prospective zones encountered in Merlin-1 encouraging
· Results on acreage adjacent to Icewine have positive implications
Sidewall cores, mud gas and fluid samples taken from Merlin-1 are now undergoing testing to determine oil saturation, oil typing, PVT characteristics, porosity, permeability and rock mechanics. Cuttings will also go through a Volatiles Analysis Service ("VAS") to assist with the interpretation of the results from the well.
The rough schedule of testing and results is as follows:
· Core photography (white and UV light) and geological descriptions 2-3 weeks
· Isotope analysis of mud gas 2-4 weeks
· VAS on cuttings 2-4 weeks
· Results from centrifugal spin out of oil samples from select cores 3-4 weeks
· Routine core analysis including saturations from Dean Stark 4-8 weeks
· Fluid analysis with oil geochemistry 5-10 weeks
These results will then be integrated into a final petrophysical interpretation.
During the drilling of Merlin-1 several prospective zones were encountered that had previously been unmapped. These zones exhibited good shows with potential for pay, subject to results from the testing mentioned above. An initial mapping exercise has indicated that these zones may be of similar magnitude in terms of volumetric range as the originally targeted primary zones. Further work is required to confirm this; however, the early work is encouraging.
88 Energy has also been closely monitoring activity nearby to the northern border of its Project Icewine acreage, where a flow of light oil from the Kuparuk has been reported from the Talitha-A well. (See Pantheon Resources AIM:PANR press release dated 19th April 2021). Additional insights into the wettability of the Kuparuk formation have also been highlighted as part of the results from Talitha-A, which may have positive ramifications for 88E's previous interpretation of this horizon. All three wells drilled by 88 Energy at Project Icewine have encountered good quality reservoir in the Kuparuk formation, with indications of hydrocarbons. These had previously been interpreted as likely gas condensate or residual oil and no mapped targets had been identified, as this was not a play that 88E had been pursuing. The results at Talitha-A are highly encouraging regionally for the Kuparuk, including across Project Icewine, and the 88E internal geoscience team is now re-assessing the potential across our acreage.
It is also evident that several of the other prospective horizons encountered in Talitha-A, where pay has been interpreted by Pantheon, extend into Project Icewine acreage.
Managing Director, David Wall, commented: "The oil shows and other encouragement seen in the Merlin-1 well bodes well for the potential at Project Peregrine and we look forward to providing the results from the laboratory analysis over the coming weeks.
It is also highly positive to see pay zones and a flow rate of light oil achieved from zones on adjacent acreage that are also prospective at Project Icewine, where an internal review has commenced to determine the significance of the neighbouring results."

About Project Peregrine
Project Peregrine is located in the NPR-A region of the North Slope of Alaska and encompasses ~195,000 contiguous acres. It is situated on trend to recent discoveries in a newly successful play type in topset sands in the Nanushuk formation. 88 Energy has a 100% working interest in the project that will reduce to 50% post the completion of funding as part of a recent farm-in, whereby 88E is carried on the first US$10m (of an initially estimated US$12.6m total cost) for the Merlin-1 well.
The Merlin-1 well was spudded in March 2021 and targeted 645 million barrels of gross mean prospective resource#. Wireline logging at Merlin-1 is now complete and interpretation of results is underway. A second well, Harrier-1, is planned to be drilled in 2022 and is targeting gross mean prospective resource of 417 million barrels#.

#Please refer to release dated 23 February 2021 for full details with respect to the Prospective Resource estimate, associated risking and applicable Cautionary Statement.
Each of the Merlin and Harrier prospects is located on trend to an existing discovery, in the same play type (Nanushuk topsets). This has de-risked the prospects considerably and resulted in a relatively high independently estimated geologic chance of success.
Cautionary Statement: The estimated quantities of petroleum that may be potentially recovered by the application of a future development project relate to undiscovered accumulations. These estimates have both an associated risk of discovery and a risk of development. Further exploration, appraisal and evaluation are required to determine the existence of a significant quantity of potentially movable hydrocarbons.
