Georgina Energy PLC – Revised Resource Upgrade of 37.8% EPA155 Mt Winter

REVISED RESOURCE UPGRADE OF 37.8% EPA155 MT WINTER

Georgina Energy plc, (GEX.L) wishes to advise further to its announcement on 7^th May 2025 that Mr. Maki Petkovski, an independent consultant, has provided the Company with an Independent Geological Report (“IGR”) regarding the fracture potential of the basement and Heavitree Formation at the Mt Winter Prospect in EPA155 within the Amadeus Basin, Northern Territory.  

The resultant increase is 37.8% of net attributable 2U Prospective (Recoverable) Resources based on 100% ownership of Mt Winter, as defined in the table below.

A copy of the full IGR is available on www.georginaenergy.com/investors/results-reports-presentations/

The previous volumetric assessments of the Mt Winter prospect relied solely on primary granular porosity estimates of the targeted Heavitree Formation whereas significant incremental increases in fracture porosity have been assessed in both the Heavitree. Formation and the prognosed basement granodiorite.

The Resource estimates presented are unrisked and have been determined utilising the Society of Petroleum Engineers (SPE) Petroleum Resource Management System (PRMS) guidelines of 2018, with revisions in 2022.Standard PRMS terminology is utilised in this report, presenting Resource Estimates as low 1U (P90), 2U for best estimate (P50), and as 3U for high estimate (P10) of as-yet undiscovered volumes. 

Globally, fracture porosity petroleum projects are very significant, the enormous Bach Ho petroleum field in Vietnam for example is hosted by fractured granodiorite basement similar to that prognosed at the Mt Winter prospect in the Amadeus basement.

The prospectivity of fractured porosity plays in the Amadeus Basin is further evidenced by the previously short, drilled section of the fractured basement at Mt Kitty-1 in the Amadeus basin which resulted in significant volumes of Helium (9%) and Hydrogen (11%) in 2014.

General Update

The Mt Winter EP155 ownership, originally at a projected 75%, was the subject of an RNS dated 22^nd January 2025 which referred to an increase of Company ownership to 100% on settlement of a Share Purchase Agreement. In addition to the planned re-entry of Mt Winter 1 two further wells were drilled at EPA155 which are currently being reviewed for their respective sequential re-entry potential. The Company continues to advance the re-entry program timeline following the execution of a previously announced agreement for acquisition of 100% of the Mt Winter tenement from Mosman Oil & Gas, which remains on track for completion.

Competent Person Statement

The information in this announcement relating to Resource Evaluation is based on information compiled by Mr. Maki Petkovski is a member of The American Association of Petroleum Geologists, The European Association of Geoscientists & Engineers, The Society of Petroleum Engineers, The Australian Society of Exploration Geophysicists and  The Petroleum Exploration Society of Australia, 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.

Mr. Maki Petkovski consents to the inclusion in the report of the matters based on his information in the form and context in which it appears.

Anthony Hamilton, Chief Executive Officer of Georgina Energy, commented:

“We are delighted with a 37.8% increase in recoverable resources at Mt Winter, as it further justifies our hard work in bringing the asset to a pre-drill stage. Our technical team has been working tirelessly to complete drilling permitting and tenement applications for the the well re-entry programs for both Hussar & Mt Winter. The increase (Helium, Hydrogen and natural gas) to the potentially recoverable resources in our Mt Winter asset is regarded as a major milestone in our program to re-develop low-risk Helium, Hydrogen and natural gas projects in Australia.”

Notes to Editors

Georgina Energy aims to become a leading player in the global energy market and is focused on establishing itself among the top producers of helium and hydrogen worldwide. With a strategic approach and leveraging the experienced management team’s expertise, Georgina Energy aims to capitalize on opportunities in these critical energy sectors. 

Georgina Energy has two principal onshore interests held through its wholly owned Australian subsidiary, Westmarket O&G.  The first, the Hussar Prospect is located in the Officer Basin in Western Australia and Westmarket O&G holds a 100% working interest in the exploration permit.  The second, the EPA155 Mt Winter Prospect, is in the Amadeus Basin in the Northern Territory, subject to the completion of Sale Agreement Georgina Energy will hold a 100% working interest.

In line with market demand trends, Georgina Energy is well-positioned to capitalize on the growing gap between supply and demand for hydrogen and helium with the resource potential of EPA155 Mt Winter and EP513 Hussar projects for their potential accumulations.
