Highlights

  • Gold Hydrogen reported successful Ramsay 1 flow testing, with helium flowing to surface, separated, purified and bottled during July 2026.
  • Ramsay 1 flow testing demonstrated helium rates of up to 24.3 Mscf/day and raw gas rates of up to 128 Mscf/day.
  • The company is progressing further testing at Ramsay 2 and Ramsay 3 to assess broader reservoir potential for helium and natural hydrogen.
  • Gold Hydrogen continues evaluating potential commercial pathways, including helium production and future natural hydrogen applications.

Gold Hydrogen Limited (ASX:GHY) is moving through a critical evaluation phase at its Ramsay Project in South Australia, with recent flow-testing results providing further insight into the potential scale of its helium and natural hydrogen opportunity.

The company’s most recent operational milestone came in August 2026, when Gold Hydrogen reported that Ramsay 1 flow-test results had enhanced the helium development pathway after successfully flowing helium to surface, separating and purifying the gas.

The Ramsay Project, located on South Australia’s Yorke Peninsula, remains the centrepiece of Gold Hydrogen’s strategy. The project is focused on assessing naturally occurring hydrogen and helium resources, commodities that have attracted increasing attention due to their potential role in future energy systems and industrial applications.

However, while recent results have improved technical understanding, the project remains in the evaluation and development-planning phase. Commercial production will require further testing, resource definition, technical studies, approvals and significant future investment.

Ramsay Flow Testing

The 2026 Ramsay testing campaign represents an important stage in reducing technical uncertainty around the project.

Gold Hydrogen’s Ramsay 1 well successfully demonstrated that helium could flow to surface and be processed through separation and purification steps. The company reported helium flow rates of up to 24.3 Mscf/day, with raw gas flow rates reaching approximately 128 Mscf/day.

The company said the results indicated reservoir productivity was not the primary constraint during the test, with limitations instead associated with installed pump capacity.

The outcome is significant because demonstrating that helium can be extracted and purified is an important technical milestone before considering larger-scale development.

Earlier in the testing program, Gold Hydrogen also confirmed helium had flowed through the Ramsay 1 system, with samples collected for further compositional and isotopic analysis, including helium-3 assessment.

These technical datasets are intended to support future resource evaluation and development planning.

Helium Opportunity

Helium is an important industrial gas used across sectors including medical imaging, semiconductor manufacturing, aerospace, scientific research and advanced manufacturing.

Supply security has become an increasing focus because global helium production is concentrated among a limited number of suppliers.

Gold Hydrogen has positioned Ramsay as a potential domestic helium source for Australia, a country that currently relies heavily on imported supply.

The company believes the Ramsay Project could eventually support helium production through a dissolved-gas-in-water development model, similar to projects operating internationally.

However, moving from a successful flow test to commercial production requires several additional steps.

These include defining commercially recoverable resources, determining processing requirements, completing economic studies, securing approvals and establishing the infrastructure required for production.

The recent results therefore improve the technical case but do not yet establish a final development outcome.

Natural Hydrogen Potential

While helium has been the primary focus of recent testing, Gold Hydrogen also continues to assess the natural hydrogen potential of Ramsay.

The company has previously highlighted hydrogen-bearing formations across the project area and designed its 2026 testing campaign to evaluate both helium and natural hydrogen reservoirs.

Natural hydrogen has emerged as an area of growing exploration interest because it represents a naturally occurring source of hydrogen rather than hydrogen produced through industrial processes.

The potential advantage is that naturally occurring hydrogen could offer a lower-carbon pathway if commercial extraction can be achieved.

However, natural hydrogen remains an emerging industry, with fewer established commercial projects compared with conventional energy resources.

For Gold Hydrogen, proving the geology and developing a commercially viable extraction model will be central to unlocking the opportunity.

Further Testing

Following Ramsay 1 results, the company has continued advancing additional Well Testing activities.

The broader 2026 campaign includes Ramsay 2 and Ramsay 3 testing to gather further information on helium and natural hydrogen-bearing zones.

Earlier operational updates confirmed that Ramsay 1, Ramsay 2 and Ramsay 3 were included in the planned flow-testing campaign, with Ramsay 3 designed to utilise higher-capacity pumping equipment.

The purpose of the expanded testing program is to improve understanding of reservoir behaviour, flow rates, pressure characteristics and potential commercial development pathways.

The results from multiple wells will be important because a single successful well does not necessarily demonstrate that a project can support long-term commercial production.

A larger dataset provides greater confidence around reservoir continuity and development planning.

Commercial Pathway

Gold Hydrogen has identified several potential commercial pathways for Ramsay.

These include helium production, natural hydrogen development and potential industrial partnerships.

The company has previously entered discussions around possible Downstream opportunities, including studies associated with potential natural hydrogen applications.

A successful commercial pathway would likely require collaboration with specialist infrastructure providers, customers and potentially strategic investors.

Energy projects typically require significant capital expenditure, meaning project economics, financing Options and customer arrangements will become increasingly important as Gold Hydrogen progresses.

At the current stage, the company remains focused on technical validation rather than production.

Investor Focus

For Gold Hydrogen (ASX:GHY), the next major milestones are likely to come from continued reservoir evaluation and the transition from exploration results toward development studies.

Investors will be monitoring further Ramsay 2 and Ramsay 3 testing, resource-definition work, potential commercial partnerships and any progress toward feasibility studies.

The company’s ability to demonstrate consistent flow performance across multiple wells will be particularly important.

Equally, converting technical success into a commercially viable helium or hydrogen project will require careful assessment of costs, infrastructure requirements and market demand.

The Ramsay Project has moved forward significantly through successful flow testing, but the remaining pathway from exploration success to production remains substantial.

Final Takeaway

Gold Hydrogen (ASX:GHY) has strengthened the technical case for its Ramsay Project after successful helium flow testing and purification milestones.

The Ramsay 1 results demonstrated helium flowing to surface, with reported helium rates of up to 24.3 Mscf/day and raw gas rates of up to 128 Mscf/day.

The company now faces the next stage of proving whether those results can support a broader commercial development.

Further testing, resource evaluation, technical studies and potential project partnerships will determine whether Ramsay can progress from an exploration opportunity into a future helium and natural hydrogen development.
