Geological and Community Risks Loom as Gold Hydrogen Pushes Ramsay Project

Energy By Maxwell Dee 3 min read

Gold Hydrogen Limited has completed drilling at Ramsay 3, confirming world-class natural hydrogen purity levels up to 97%, and is progressing with its Ramsay 4 well to further appraise its promising hydrogen project in South Australia.

  • Ramsay 3 drilling completed at 884.2m depth with production casing installed
  • Natural hydrogen purity confirmed up to 97% in Parara Formation samples
  • Multiple elevated hydrogen and helium zones detected across formations
  • Continuity of hydrogen zones confirmed over 2.3 km between Ramsay 2 and 3
  • Completions and Well Test Program planned for Q1 2026 to assess flow potential

Drilling Milestone at Ramsay 3

Gold Hydrogen Limited has successfully completed drilling at its Ramsay 3 well, reaching a total depth of 884.2 meters. This milestone marks a significant step in the company’s ongoing campaign to unlock natural hydrogen resources in South Australia. The well was cased with production tubing and equipped with fiber optic cables to gather detailed temperature and acoustic data, laying the groundwork for future reservoir evaluation.

Exceptional Natural Hydrogen Purity

Initial laboratory analyses have revealed natural hydrogen purity levels of up to 97% (air corrected) within the Parara Formation, a figure that positions the Ramsay Project among the world’s leading natural hydrogen discoveries. Alongside hydrogen, elevated helium concentrations were also detected, enhancing the potential value of the resource. These findings reinforce the geological model that predicts a laterally extensive hydrogen system.

Geological Continuity and Formation Evaluation

Wireline logging and petrophysical analysis conducted by Baker Hughes have identified multiple stacked gas zones across the Parara, Kulpara, and Hiltaba Granite formations. Notably, the gas signatures observed at Ramsay 3 correlate strongly with those from the earlier Ramsay 2 well, confirming continuity of the hydrogen-bearing zones over a 2.3-kilometer up-dip distance. This continuity significantly strengthens confidence in the project’s resource potential.

Next Steps – Ramsay 4 and Well Testing

With Ramsay 3 now complete, the drilling rig has mobilized to Ramsay 4, located 500 meters north of Ramsay 2, to continue the appraisal campaign. Meanwhile, preparations are underway for a Completions and Well Test Program scheduled for the first quarter of 2026. This program will focus on flow testing the identified hydrogen and helium zones, utilizing data from fiber optic sensors and bottom-hole gauges to optimize production strategies.

Strategic Partnerships and Risk Considerations

The Ramsay Project benefits from strategic investments by industry heavyweights Toyota Motor Corporation, Mitsubishi Gas Chemical, and ENEOS Xplora, underscoring the growing interest in natural hydrogen as a clean energy source. However, the company acknowledges geological uncertainties and the need for ongoing community engagement, given the project’s proximity to agricultural lands and protected areas on Yorke Peninsula and Kangaroo Island. These factors will require careful management as development progresses.

Bottom Line?

As Gold Hydrogen advances its drilling and testing, the market will watch closely for flow test results that could validate this world-class hydrogen opportunity.

Questions in the middle?

  • What flow rates and commercial viability will the upcoming well tests reveal?
  • How will community and environmental concerns be addressed given the project’s sensitive location?
  • What impact will strategic partners have on accelerating development and commercialization?
