Georgina Energy (GEX) , an Australia-focused natural resources explorer, issued an update on its core asset EPA155 Mt Winter in the Amadeus Basin, Northern Territory, Australia, targeting significant deposits of natural gas, hydrogen and helium.
Georgina announced a 37.8% upgrade in net 2U/P50 recoverable resources at Mt Winter, based on 100% ownership of the asset. This reflects GEX's full acquisition of EPA155 Mt Winter from Mosman Oil & Gas in early 2025.
The new geological report estimates unrisked 2U prospective resources of 234 bcfg helium, 214 bcfg hydrogen, and 1,734 bcfg hydrocarbons. This builds on a prior 20% resource upgrade from May 7, 2025, which has now been boosted further by 37.8%.
Anthony Hamilton, CEO of Georgina Energy, commenting: "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 and 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."

Georgina reports another major resource upgrade at its core asset in Australia, the EPA155 Mt Winter in the Amadeus Basin, Northern Territory. The new estimate boosts the previous 20% upgrade by another 37.8%, in addition to accounting for 100% ownership - up from 75% following GEX's contracted full acquisition of the asset from Mosman Oil & Gas in early 2025. Permitting for EPA155 is in the final stages and expected to be finalised shortly.
By latest estimation, Mt Winter hosts unrisked 2U/P50 recoverable resources of 234 bcfg helium, 214 bcfg hydrogen, and 1,734 bcfg hydrocarbons net to GEX, based on GEX's full funding of the Mt Winter-1 well reentry program. The previous estimate relied solely on primary granular porosity, whereas the new estimate accounts for significant increases in fracture porosity assessed in the target formation.
Globally, fracture porosity petroleum projects are very significant. For instance, the enormous Bach Ho petroleum field in Vietnam is hosted by fractured granodiorite basement, similar to that prognosed at the Mt Winter prospect. The prospectivity of fractured porosity plays in the Amadeus Basin is further evidenced by the Mt Kitty-1 well, which yielded significant volumes of helium (9%) and hydrogen (11%) in 2014.
Additionally, a new 60km2 structural closure was recently identified at Mt Winter, offering significant potential to find new targets and boost future production. In addition to Mt Winter-1, two other wells drilled in EPA155 are currently under review for their respective sequential reentry potential.
In early 2025, GEX announced the full acquisition of EPA155 Mt Winter from Mosman Oil & Gas, bringing the group's entire Australian portfolio under 100% ownership. The deal remains on track for completion and should accelerate the Mt Winter-1 well reentry program following drill approval.
While Georgina is still in the pre-revenue phase, it has made substantial progress over the past year in de-risking its assets in Australia and advancing toward drill-ready status. With a focus on launching its maiden drilling campaign at EP513 Hussar, alongside the Mt Winter-1 well reentry program, the company is poised to unlock significant value over the next year.
