Gold Hydrogen Advances Ramsay Helium Project with World-Leading Purity and Commercial Viability

Ramsay Emerges as Potential Helium Game-Changer

Gold Hydrogen Limited (ASX:GHY) is positioning its Ramsay Project on South Australia's Yorke Peninsula as a rare domestic source of Helium, a critical gas now in short supply worldwide. The company reported air-corrected Helium purities reaching 36.9%, which it describes as world-leading, alongside Natural Hydrogen purities up to 97%. These findings come amid global supply shocks, including a 30–35% cut in traded Helium following strikes on Qatar's Ras Laffan facility, and the closure of Australia's sole Darwin LNG Helium plant in late 2023, leaving Australia and New Zealand fully reliant on imports.

Independent commercial modelling by Worley Consulting suggests Ramsay could be commercially viable with as few as two wells, each sustaining Helium flow rates of approximately 29 thousand standard cubic feet per day. Scaling to ten wells improves key financial metrics such as NPV and IRR, although these scenarios remain hypothetical pending flow testing results. Worley is collaborating with Gold Hydrogen to refine these models alongside the upcoming flow testing campaign scheduled for June 2026.

Multiple Pathways Signal Flexible Commercial Strategy

Gold Hydrogen is advancing a multi-pronged commercialisation approach. Alongside Helium production, the company is exploring Natural Hydrogen applications including green methanol production, power generation via hydrogen fuel cells, and compressed gas trucking trials. Quantum Technology Corp, a Canadian firm specialising in modular Helium and Hydrogen purification plants, has provided access to commercial-scale pilot units, underscoring the technical readiness for rapid deployment.

The company plans an accelerated Front End Engineering Design (FEED) process focused initially on Helium, potentially establishing it as the first commercial platform before scaling to longer-term Natural Hydrogen projects. This strategy aims to capitalise on the urgent market need for sovereign Helium supply in Australia, a sentiment echoed by Gold Hydrogen Chairman Alexander Downer, who advocates for Helium’s reinstatement on Australia’s Critical Minerals List.

Robust Data Underpins Resource Confidence

Gold Hydrogen's confidence in Ramsay's resource potential rests on extensive datasets including a 10,529 line kilometre airborne survey, seismic and fluid inclusion studies, and multiple drilling campaigns. Independent assessments estimate unrisked Helium prospective resources with a mean of 96 billion cubic feet across the project area, albeit with geological and development risks still to be resolved through forthcoming flow testing.

Notably, Helium-3 isotopes detected by Oxford University laboratories add a rare dimension to the project's profile, with concentrations up to 901 parts per trillion. This isotope is critical for advanced technologies, further elevating Ramsay’s strategic value.

Gold Hydrogen's upcoming flow testing, which follows recent drilling successes confirming 97% pure Natural Hydrogen, will be pivotal in converting prospective resources into contingent resources and refining commercial models. Early results and the company’s ongoing engagement with strategic partners and government bodies will be closely watched by the market.

Global Supply Crunch Sharpens Strategic Importance

The timing of Ramsay’s development ambitions coincides with a global Helium supply crisis. Qatar and the United States dominate supply, together accounting for nearly 90% of the market, and recent geopolitical disruptions have removed a significant portion of this supply for at least 12 to 18 months. Spot prices have doubled, intensifying demand pressures from semiconductor manufacturing, AI data centres, MRI technology, and defence applications.

Gold Hydrogen’s initiative to re-establish a domestic Helium supply chain resonates with broader strategic imperatives, as highlighted in commentary from the Australian Strategic Policy Institute stressing the criticality of Helium to chip manufacturing. The company is currently fielding interest from potential offtakers, technology vendors, investors, and government agencies, setting the stage for Ramsay to become a cornerstone of Australia’s strategic materials landscape.

This development builds on the company’s prior progress, including its recent Ramsay flow test program mobilisation and the confirmation of 97% pure Natural Hydrogen at Ramsay 3. These milestones underscore the technical and commercial momentum behind Gold Hydrogen’s ambitions.
