H3 Energy Limited is launching a detailed assessment of helium and hydrogen potential at its Milford and Milford East structures, aiming to unlock high-value gas resources in the underexplored Officer Basin.
- Assessment focuses on Milford and Milford East structures within Alinya Project
- Previous estimates show 209 Bcf helium and 1.2 billion kg hydrogen at Rickerscote Prospect
- Evaluation of geological formations extending into new areas to define gas composition
- Alinya Project holds over 20 additional prospects indicating significant exploration upside
- Helium’s rising global value underpins strategic focus on high-value gas components
Exploring New Frontiers in the Officer Basin
H3 Energy Limited (ASX:H3E) has announced the commencement of a targeted technical assessment aimed at evaluating the helium and hydrogen potential of the Milford and Milford East structures within its flagship Alinya Project, located in South Australia's northwestern Officer Basin. This region has remained largely underexplored despite indications of promising oil and gas shows, positioning H3E to potentially unlock substantial new energy resources.
The company’s previous work at the Rickerscote Prospect, a key structure within the Alinya Project, revealed an estimated prospective resource of 209 billion cubic feet (Bcf) of helium alongside 1.2 billion kilograms of hydrogen. These figures, while prospective and carrying a geological chance of success between 7% and 17%, highlight the significant value that could be present in the basin’s gas systems.
A Multi-Commodity Strategy
H3E’s current program involves a comprehensive review of existing geological and geophysical data to better understand the structural configuration, reservoir characteristics, and seal integrity of the Milford and Milford East areas. A particular focus is on whether the Alinya Formation mudstone and salt seals, along with the Pindyin sandstone reservoirs, extend into these structures, which would be critical for trapping helium and hydrogen gases.
Beyond helium and hydrogen, the Alinya Project has been independently assessed to contain a prospective resource of 4.3 trillion cubic feet of gas and 1.3 billion barrels of liquids in a single structure, with more than 20 additional prospects identified across the tenure. This breadth of opportunity supports H3E’s portfolio approach, aiming to capture value across multiple gas streams while maintaining a disciplined exploration strategy.
Market Context and Strategic Implications
Helium’s market value has surged globally due to its critical applications in technology, healthcare, and scientific research, making it a highly sought-after commodity. H3E’s CEO, Nik Sykiotis, emphasised the company’s commitment to unlocking this value, noting that helium’s high value and low volume characteristics could facilitate quicker commercialisation following exploration success.
As the energy sector increasingly pivots towards cleaner alternatives, H3E’s focus on natural hydrogen and helium aligns with broader energy transition trends. The company’s exploration efforts in South Australia’s Officer Basin could position it as a key player in supplying these emerging energy resources.
While the current resource estimates remain prospective and subject to further validation, the ongoing assessment at Milford and Milford East represents a critical step in defining the scale and composition of the basin’s gas potential. Investors and industry watchers will be keen to see how these evaluations progress and what commercial opportunities may emerge.
Bottom Line?
H3 Energy’s unfolding exploration in the Officer Basin could redefine its resource base and market prospects if helium and hydrogen potential is confirmed.
Questions in the middle?
- Will the Milford and Milford East structures confirm the extension of key helium-bearing formations?
- How soon could H3 Energy move from assessment to commercial production if resources are validated?
- What impact will global helium market dynamics have on the project’s economic viability?
