Prominence Energy Secures 64,000km² Gawler Craton Landholding with Key Hydrogen Indicators

Acquisition Milestone in Natural Hydrogen

Prominence Energy Ltd (ASX – PRM) marked a pivotal moment in its corporate journey with the completion of the Gawler Natural Hydrogen Project acquisition. This follows the final regulatory approval from the South Australian Department for Energy and Mining, enabling the company to formally conclude the transaction and issue consideration securities. The acquisition positions Prominence as a significant player in the nascent natural hydrogen and helium exploration sector, securing a substantial land position across the geologically prospective Gawler Craton.

Geological Promise and Technical De-risking

The Gawler Craton is renowned for its Archean-aged terrane, featuring radiogenic granites and uranium mineralisation, which are key indicators for natural hydrogen and helium generation. Prominence’s detailed geological and geophysical assessments have identified multiple hydrogen source rocks, including the Hiltaba Granite and ferrolysis-prone lithologies, alongside several reservoir-seal pairs. These findings materially reduce exploration risk and provide a clear framework for prioritising future drilling targets.

Upcoming Field Programs and Strategic Engagements

Looking ahead, Prominence is preparing for an integrated soil-gas and groundwater geochemical survey within the Eyre Project area of PEL 803. Scheduled for early 2026, this survey aims to deliver the first systematic surface geochemical data set, validate desktop interpretations, and directly assess near-surface hydrogen and helium anomalies. Concurrently, the company’s participation in the Australian Clean Hydrogen and Carbon Capture & Storage delegation to H2MEET Korea 2025 underscores its commitment to engaging with the global hydrogen value chain.

Corporate Developments and Financial Position

Post-acquisition, Prominence completed the issuance of consideration securities to Gawler Group Holdings Pty Ltd, with performance rights converting into fully paid ordinary shares in January 2026. The board welcomed Dr Mike Fischer as a Non-Executive Director, enhancing strategic oversight, while Mr Bevan Tarratt transitioned to a Non-Executive role. Financially, the company reported exploration expenditure and administrative costs consistent with its growth phase, maintaining a cash balance of approximately A$1.16 million and nearly four quarters of funding runway based on current outgoings.

Positioning in a Growing Sector

Prominence’s acquisition and technical progress place it among the early movers in Australia’s natural hydrogen sector. With a large-scale, technically de-risked asset base and a clearly defined pathway toward systematic field validation and drilling, the company is well positioned to capitalise on the growing interest in clean energy alternatives. The coming months will be critical as field surveys commence and the company advances its exploration agenda.
