Highlights

  • Gold Hydrogen Limited (ASX:GHY) has lodged a proposed issue of securities under an Appendix 3B filing.
  • The company is advancing commercialisation pathways for its Ramsay Project on South Australia's Yorke Peninsula.
  • Ramsay flow testing has recorded helium purities of up to 36.9%, described as among the highest ever globally.
  • The company has engaged engineering firm Worley to assess the commercial viability of helium production at Ramsay.

Gold Hydrogen Limited (ASX:GHY), the South Australian-focused natural hydrogen and helium explorer, has lodged a proposed issue of securities, a regulatory disclosure that forms part of the company's ongoing Capital management activities. The announcement arrives as Gold Hydrogen pursues a meaningful transition from exploration to potential commercial production at its flagship Ramsay Project on Yorke Peninsula.

Recent Operational Activity

The Ramsay Project has seen sustained exploration momentum over recent periods. A multi-well campaign including Ramsay 1, 2, 3, and 4 has delineated an extensive natural hydrogen and helium system across the project area. Flow testing at Ramsay 1 confirmed that helium could be flowed, separated, and purified at the surface, a milestone the company described as critical in demonstrating the project's commercial potential. Purities recorded during air-corrected testing have reached up to 36.9%, a figure the company notes places Ramsay among the highest-grade helium occurrences reported worldwide.

Helium Focus

Management has indicated that helium development at Ramsay represents the immediate commercial priority, given the material that has now been flowed and purified. Engineering consultancy Worley completed an independent assessment indicating that commercial helium production may be achievable with relatively few wells, depending on flow rates. The company has pursued a front-end engineering and design process to move toward a focused helium-first development pathway, treating natural hydrogen as a longer-term upside within the same system. Independent experts have noted the significance of Ramsay's Helium-3 content, which was confirmed at Oxford University's specialist noble gas laboratory at levels far exceeding atmospheric background.

Market Context

Australia currently imports all of its domestic helium requirement, a situation that has persisted since the closure of a Darwin processing Facility several years ago. Global helium Supply has faced intermittent disruptions, including those related to major production centres overseas, creating strategic interest in alternative domestic sources. Gold Hydrogen has highlighted this supply gap as an opportunity for Ramsay to serve Australian industrial, scientific, and technology end markets. Helium's use in semiconductors, medical imaging, and defence applications underpins its classification as a critical mineral in several jurisdictions.

Capital Structure and Funding

The proposed issue of securities forms part of the company's approach to maintaining a Capital Structure aligned with its exploration and development objectives. Without commenting on the specific terms or quantum of the issue, the company has historically raised funds through institutional placements and rights offers. Managing capital access through ASX-compliant processes such as the Appendix 3B lodgement ensures shareholders are kept informed of any changes to the company's issued securities in a timely manner.

Project Scale and Resource Base

Gold Hydrogen holds an extensive land package across Yorke Peninsula and Kangaroo Island, covering a combined natural hydrogen and helium province estimated to span tens of thousands of square kilometres. An independent prospective resource for natural hydrogen and helium has been certified, providing a technical foundation for the company's longer-term development ambitions. Connectivity of the gas-bearing zones across multiple wells has been a key theme from the drilling and flow testing campaign to date.

Key Insights

Gold Hydrogen's proposed issue of securities reflects the company's ongoing effort to fund its transition from early-stage explorer to potential helium and natural hydrogen producer. The Ramsay Project's demonstrated flow and purification credentials, combined with the strategic context of Australia's complete reliance on helium imports, position the company at an intersection of critical mineral interest and frontier energy development. Progress on engineering and commercial assessment will be a key indicator for the project's trajectory in the periods ahead.
