Ramsay Wells Confirm High-Purity Hydrogen and Helium, $6.6M Spent on Exploration

Exploration Success at Ramsay

Gold Hydrogen Limited (ASX – GHY) has delivered a promising update from its Ramsay Project on South Australia's Yorke Peninsula, confirming the presence of high-purity Natural Hydrogen and Helium in newly drilled wells. The Ramsay 3 well, drilled to 884 metres, returned initial laboratory results showing Natural Hydrogen purity levels reaching 97% (air corrected) within the Parara Limestone formation. Elevated Helium levels were also detected at various depths in the Kulpara Dolomite formation, reinforcing the potential for a commercially viable resource.

The Ramsay 4 well, drilled approximately 500 metres from Ramsay 2, intersected multiple porous and permeable zones across the Parara, Kulpara, and Winulta formations. These findings suggest a lateral continuity of the gas-bearing formations, strengthening the geological model for a significant Natural Hydrogen and Helium system in the region.

Strategic Well Design and Upcoming Testing

Building on prior drilling campaigns, Gold Hydrogen designed the 2025 wells with larger diameter bores and 7-inch casing to facilitate more comprehensive well testing scheduled for early 2026. This testing aims to move both gases to surface under controlled conditions, providing critical data to support pilot project designs and assess commercial viability.

The company is awaiting full laboratory analyses from Petrolab in Adelaide for both Ramsay 3 and 4 wells, which will further clarify gas composition and reservoir characteristics. The upcoming well testing campaign represents a pivotal step in transitioning from exploration to potential development.

Advancing Green Methanol and Helium Commercialisation

Beyond exploration, Gold Hydrogen is advancing feasibility studies for green methanol production, leveraging the abundant agricultural biomass and renewable energy resources of the Yorke Peninsula. Green methanol, a liquid fuel compatible with existing shipping and aviation engines, offers a promising pathway to decarbonisation. The company has appointed industry expert Simon Talbot to lead this initiative, aiming to capitalise on the cost advantages of Natural Hydrogen over electrolytic hydrogen.

Simultaneously, Gold Hydrogen has engaged Worley to conduct an engineering study focused on the commercialisation of Helium, a critical and scarce resource currently imported into Australia. The high purity Helium detected at Ramsay positions the project well to meet growing demand in medical, defence, and technology sectors.

Financial and Operational Overview

During the December quarter, Gold Hydrogen invested approximately A$6.6 million in exploration activities, primarily focused on the Ramsay Project. No production or development expenditures were recorded, reflecting the early stage of the project. The company ended the quarter with A$16.7 million in cash reserves, providing a runway for upcoming drilling and testing programs.

Gold Hydrogen holds extensive exploration licenses and applications covering over 75,000 square kilometres in South Australia, positioning it as a leading player in the emerging Natural Hydrogen and Helium sector. The company continues to engage with industry partners to explore mid- and downstream commercial opportunities.

Looking Ahead

As Gold Hydrogen prepares for its 2026 well testing campaign, the market will be watching closely for results that could validate the commercial potential of this pioneering project. The combination of high-purity Natural Hydrogen, valuable Helium, and strategic green methanol initiatives could position the Ramsay Project as a cornerstone in Australia's clean energy transition.
