Gold Hydrogen Ltd (ASX:GHY) continues to investigate the multi-element gas bounty of the flagship Ramsay Natural Hydrogen Project in South Australia with the Ramsay 2 well demonstrating very high levels of helium, alongside its hydrogen content.
The well, which represents one of the first natural hydrogen exploration wells in Australia, appears to have helium concentrations of up to 6.8% in raw gas from the Kulpara Formation, positioning the project as a world-class helium resource should those numbers be repeated across the tenure.
Commercially produced helium is often found at concentrations of less than 1%.
The discovery also represents a novel foray into non-petroleum-based helium exploration, supporting the theory the two gases (helium and hydrogen) occur concurrently.
Pioneering advancements in the field
“These initial helium results from Ramsay 2 are truly world-class,” Gold Hydrogen managing director Neil McDonald said.
“While we were already pleasantly surprised by the previously tested and announced helium found at Ramsay 1, the results from Ramsay 2 of 6.8% helium in the raw gas do not come as a complete shock.
“Just last week, I had the privilege of attending the World Natural Hydrogen Conference (HNAT), where international scientists shared theories about the simultaneous discovery of helium alongside natural hydrogen.
“These findings further affirm our commitment to pioneering advancements in the field and underscore the global significance of the Ramsay project.”
GHY advises that the results – although from proven and respected testing methodologies and standards – are samples only, with further exploration, analysis and future flow testing needed.
Ramsay 2 Well progress
Ramsay 2 reached its final total depth of 1,068 metres on December 1 while logging operations are also complete and the casing has been securely cemented in place.
The company says it has meticulously collected mud gas samples down the well in real-time during drilling, revealing multiple zones with high hydrogen concentrations through the Parara Limestones, the Kulpara Formation and the granitic basement.
Testing is ongoing – which will be independently validated by a specialised third-party laboratory to ensure credibility – with results expected to be received next week and further announcements to follow.
GHY says Ramsay 2’s initial results point to potential for a “significant” helium reservoir and a prolific helium system on the project site, complementing the established hydrogen play.
The company will employ further exploration, analysis and eventually flow testing to produce a clear picture of Ramsay’s true potential.
