Independent Petroleum Reserves and Resources Evaluation Identifies 13 Billion Barrel Potential at Jameson Land Basin, Greenland

80 Mile PLC ('80M' or the 'Company'), the AIM, FSE, and OTC listed exploration and development company with projects in Greenland, Finland and Italy, notes the recent announcement as of October 28^th,  by its US joint venture partner, March GL Company ("March GL") and Pelican (PELI.Nasdaq) ("Pelican"), regarding the results of an independent assessment and prospective resources report prepared by Sproule ERCE (the "Sproule Report") confirming the world-class potential of the Jameson Land Basin ("Jameson"), located in Eastern Greenland.

Highlights

·      Independent assessment by US based oil field specialists, Sproule ERCE estimate 13.03 billion barrels (P10) of gross un-risked recoverable prospective oil resources across the upper levels of the Jameson Basin

o  The report also highlights potential upside outside these already identified target areas, across the broader licence and at depth. Specifically, the Permian base layer

·      80 Mile's attributable share equates to approximately 3.9 billion barrels (P10) based on its 30% interest post earn-in completion

·      Report identifies 58 prospects and leads, putting Jameson among the most prospective undrilled basins globally

·    First, free carried, drilling operations expected to commence in H226, fully funded and operated by the world's experts in oil drilling

As previously announced, 80 Mile and March GL entered into a binding joint venture agreement for drilling to commence at Jameson. Under this agreement, March GL will fund 100% of the costs associated with up to two exploration wells (each to a minimum depth of 3,500 metres) designed to delineate the hydrocarbon potential of the Jameson Basin.

In return, March GL may earn up to a 70% working interest, with 80 Mile retaining a 30% interest through its wholly owned subsidiary White Flame Energy A/S upon completion of the second well. Until that time, 80 Mile retains 100% legal ownership of the licences covering approximately two million acres in Eastern Greenland.

The Sproule Report, prepared in accordance with the Petroleum Resources Management System ("PRMS 2018"), assesses total gross unrisked recoverable prospective resources of approximately 13.03 billion barrels (P10) across 58 identified prospects. The report can be found on the SEC website here;

Of this, 80 Mile's attributable interest under the full earn-in structure equates to approximately 3.9 billion barrels (P10).

The report also highlights the multiple, stacked, large and high-quality structural reservoirs and stratigraphic traps, as well as the significant exploration upside across the basin. Sproule's findings confirm Jameson's scale and geological quality, ranking it amongst the world's most significant untested hydrocarbon provinces.

Preparations for drilling are ongoing, with Halliburton contracted to provide drilling services and logistics support, and IPT Well Solutions appointed as project manager. Mobilisation of a 3,500-metre-capable rig is now scheduled with shipping and logistics agreements already executed with leading service providers.

Competent Person Report

The information in this announcement relating to Prospective Resources of the Jameson Land Basin, Greenland Evaluation is based on information compiled by Jeffrey Aldrich, Principal Geoscientist P.G., L.P.G, Sproule ERCE. Certified Petroleum Geologist (CPG), Jeffrey Aldrich is a member of The American Association of Petroleum Geologists and has sufficient experience of petroleum reserves and resources evaluation under consideration, and to the activity he is undertaking to qualify as a Competent Person.

The scientific and technical disclosure included in the Sproule Report has been reviewed and approved by Eric Sondergaard, a director of 80 Mile PLC, who is also a Member of the Alberta Association of Professional Geoscientists and Engineers (APEGA). Mr. Sondergaard has sufficient experience, to qualify as a Qualified Person ('QP') as defined by the AIM rules. Mr. Sondergaard has additionally reviewed this press release and consents to the inclusion in the press release of the matters based on his information in the form and context in which this appears.

Roderick McIllree, Executive Director of 80 Mile, commented:

"I first visited Jameson Land over a decade ago and was struck by its scale and geology. It truly is a remarkable project.

This latest report represents a major milestone for Jameson. It marks the first time the project has been formally recognised within the U.S. energy sector. Based on this report and the Pelican presentation, and on a P10 basis, Jameson now ranks as the thirteenth largest undeveloped oil accumulation globally, as filed with the SEC.

The significance of that cannot be overstated. Western Europe built its modern economies and sovereign wealth funds on North Sea oil, and it now appears that Greenland may host a comparable, and largely untapped, resource base.

With a listed and fully funded U.S. joint venture partner, soon to be renamed Greenland Energy Company, we are now positioned to drill and answer a question that has remained unresolved for more than sixty five years."

80 Mile's acquisition of White Flame Energy and the Jameson licenses in East Greenland has positioned the Company in one of the world's most compelling undrilled hydrocarbon basins. Under its agreement with March GL, drilling of two fully funded wells is set to commence, with Pelican Acquisition Corporation's merger with Greenland Exploration valuing 80 Mile's retained 30% interest in Jameson at approximately US$92 million. This acquisition and partnership significantly expand 80 Mile's exposure to the energy sector while advancing its strategy of developing both conventional and sustainable energy opportunities.

The Disko-Nuussuaq nickel-copper-cobalt-PGE project in Greenland is a primary focus for 80 Mile, 100% owned by 80 Mile PLC. Seven priority targets exhibiting spatial characteristics indicative of potential deposits on a scale comparable to renowned mining operations such as Norilsk, Voisey's Bay, and Jinchuan, will be advanced by the Company.

The Dundas Ilmenite Project, 80 Mile's most advanced asset in northwest Greenland, is fully with a JORC-compliant Mineral Resource of 117 Mt at 6.1% ilmenite and an offshore Exploration Target of up to 530 Mt. Dundas is poised to become a major supplier of high-quality ilmenite. Recent discoveries of hard rock titanium mineralisation, with bedrock samples showing nearly double the ilmenite content of previous estimates, further enhance the project's world-class potential. 80 Mile owns 100% of the Dundas Ilmenite Project under its subsidiary Dundas Titanium A/S in Greenland.

80 Mile PLC has executed an asset purchase agreement with Amaroq Minerals Ltd.
