Georgina Energy Upgrades Mt Winter Hydrogen and Helium Resource, Adds New Drill Target

Georgina Energy (GEX.L) has reported a 15% increase in its net attributable 2U Prospective Recoverable Resources of hydrogen and helium at the Mt Winter prospect in Australia’s Northern Territory. The upgrade, confirmed by independent expert Mr. Maki Petkovski, follows seismic data reprocessing and builds upon the May 2024 CPR.

The company now estimates up to 122 BCF of hydrogen and 133 BCF of helium at a 90% working interest, should Georgina fully fund the re-entry of Mt Winter-1. Plans are underway to deepen the well from 2,650m to ~2,900m to test the Heavitree Formation reservoir.

In addition, a new 60 km² structural closure has been identified northeast of Mt Winter-1, offering future drill potential pending further seismic. Negotiations for the exploration permit (EPA155) are progressing, with Georgina expected to secure 100% ownership upon completion of an Aboriginal Land Rights Agreement and related regulatory approvals.

CEO Tony Hamilton noted the significance of both the upgraded resource estimate and the discovery of an additional large target, reinforcing the company’s strategy to develop low-risk helium and hydrogen resources in Australia.

RESOURCE UPGRADE EPA155 MT WINTER

Georgina Energy plc, GEX.L is pleased to announce a significant resource upgrade at its Mt Winter Prospect (EPA155, Northern Territory). The upgrade follows the successful completion of  seismic data reprocessing and re-mapping from the Independent Competent Person, Mr Maki Petkovski. This addendum builds on the CPR of May 23, 2024, published by Al Maynard & Associates, released in the Company's Prospectus (available on the GEX website). The revised estimates take into account Georgina's assumed 75% working interest, based on the Company funding 100% of the planned Mt Winter-1 re-entry program. A copy of the CPR Addendum can be found on Georgina's website here.

Highlights

· 15% increase in net attributable 2U Prospective Recoverable Resources of helium and hydrogen

· 3% increase in natural gas resources

· Identification of a new 60km² structural closure, offering future drill target potential

· Re-entry planned at Mt Winter-1 well, with target depth extended to ~2,900m

· Exploration permit negotiations progressing; Company to hold 100% interest in EPA155 upon completion

Resource Upgrade Summary

The updated seismic mapping and reprocessing has enabled a comprehensive review of the resource potential of the Mt Winter Prospect within EPA155, Northern Territory, resulting in an increase in net attributable 2U Prospective (Recoverable) Resources of 15% of both Helium and Hydrogen and a 3% increase in net attributable 2U Prospective Recoverable) Resources of natural gas.

Resource estimates presented are unrisked and have been determined utilising the Society of Petroleum Engineers (SPE) Petroleum Resource Management System (PRMS) 2018 and 2011 (Guideline) principals. 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. 

New Closure Identified and Development Outlook

In addition, a large structural high of up to 60 km2 closure to the north-east of the Mt Winter-1 well and to the north of the existing Mt Winter Prospect has been identified and represents a significant additional potential closure as a future drilling candidate subject to further additional seismic.

The completion of the seismic reprocessing and re-mapping support the Company's planned re-entry at the Mt Winter-1 well, which was originally drilled in 1982 to a depth of 2,650m in the Gillen Salt. Georgina is now planning the re-entry and deepening of Mt Winter-1 to approximately 2,900m to test the targeted helium, hydrogen and natural gas potential in the subsalt Heavitree Formation reservoir.

Update on Exploration Permit

The Company has executed the necessary Confidentiality Agreements and is currently negotiating the Aboriginal Land Rights Agreement ("ALRA") to be lodged with the Northern Territory Department of Mining and Energy ("DME") under the Petroleum Act 1984 (NT) to secure the granting of the exploration permit and consequent settlement of the previously announced Share Sale Agreement with Oilco. Georgina will hold a 100% working interest in EPA155.

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

"We are very pleased with this outstanding 15% increase (helium & hydrogen) to the recoverable resources in our Mt Winter asset, as well as the identification of a second larger target structure within our existing permit area which could provide significant potential to increase the resource.

We anticipate receiving the grant of the exploration permit and are working well with the regulators of the NT DME. Georgina remains focused on re-entering both the Hussar and Mt Winter wells as part of our program to 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.
