- Laboratory analysis confirms elevated helium and widespread natural hydrogen
- Helium measured more than 12 times atmospheric background levels
- Hydrogen concentrations more than 6,200 times atmospheric background levels
- Results validate Prominence’s exploration model
Prominence Energy (ASX:PRM) has received a confidence boost with results of independent laboratory tests confirming the natural helium and hydrogen potential of its PEL 803 permit in South Australia.

Gas chromatography (GC) analysis has now been completed by Atherium on soil gas samples collected during the recently completed PEL 803 soil gas survey (SGS) on the Eyre Peninsula.
“Independent validation of helium and hydrogen anomalies in PEL 803 is a significant de-risking milestone for the project,” COO, Dr Krista Davies, said.
“Importantly, these results were obtained under recharge conditions approximately 24 hours after probe installation, increasing our confidence that we are detecting naturally migrating subsurface gases.
“The results strengthen our geological model and provide a robust dataset for defining and ranking drillable targets. Our focus now turns to integrating these results with geophysical data to identify the highest priority locations for future seismic acquisition and drilling.”
Dr Davies said the independent laboratory results confirm strongly elevated helium and hydrogen concentrations across the survey area and independently validate the company’s exploration model at PEL 803.
“The results represent a significant technical milestone and provide a stronger foundation for advancing PEL 803 toward seismic acquisition and target definition.”
The laboratory program analysed 63 soil gas samples collected during the PEL 803 soil gas survey.
Results confirmed elevated hydrogen concentrations above atmospheric background levels throughout the survey area. The highest hydrogen anomaly measured a concentration of 3,427 parts per million (ppm). A total of 40 (64%) samples returned elevated hydrogen values above atmospheric background, demonstrating the presence of a widespread hydrogen system across PEL 803.
Elevated helium was also measured, up to a maximum of 63 ppm.
Dr Davies said the results complement the company’s earlier field measurements and support the interpretation of an active subsurface gas migration system.
