GAWLER HYDROGEN PROJECTSOUTH AUSTRALIAProminence Energy announced on 23rd June 2025 that it had entered into a binding agreement to acquire 100% of the issued capital of Gawler Group Holdings Pty Ltd for the purposes of acquiring 100% interest in a total of nine (9) petroleum exploration licence applications (“PELAs”) comprising the Northern Hinge Project and Eyre Project in South Australia (the “Gawler Hydrogen Project”). The Transaction is currently awaiting regulatory approvals, as per the ASX announcement made on 20th October 2025.
Eyre Project The Eyre Project consists of one PEL (803) and three PELAs (PELA 749, 750 & 751). The blocks cover a combined area of approximately 29,126km². See Figure 1. The Eyre Project sits on the cratonic Gawler Craton Archean Crust and is considered prospective for the occurrence of natural hydrogen, helium and other associated gases. Radiogenic Hiltaba Granites and localised uranium deposits are present in several areas throughout the Eyre Project, which provide evidence for the generation of hydrogen (and helium) as a byproduct of mineralisation. Additionally, a large conductivity anomaly identified from regional magnetotelluric data through the project area may represent a crustal scale mantle plume, facilitating the migration of primordial hydrogen to surface.Northern Hinge Project
The Northern Hinge Project consists of five PELAs (PELA 566, 581, 748, 752 & 753). The PELAs cover a combined area of approximately 34,133km². See Figure 1. The Northern Hinge Project comprises of a northern extension of the Adelaide Hinge Zone, which includes the boundary of the Archean Gawler Craton, representing excellent radiogenic and geochemical source pathways for the generation and migration of natural hydrogen and helium.
