Gold Hydrogen Commences Drilling at Ramsay 3
Gold Hydrogen Limited (ASX: GHY) has commenced drilling at Ramsay 3, marking the official start of its 2025–26 exploration and well-testing campaign in South Australia.
The Ramsay 3 exploration well was spudded at 10:00am local time on November 10, 2025, near Minlaton, on the Yorke Peninsula, within Petroleum Exploration Licence (PEL) 687. The campaign aims to delineate the presence, scale, and production potential of natural hydrogen and helium within the Ramsay Project area — one of the world’s most promising geological hydrogen provinces.
The multi-well program builds directly on the successful hydrogen and helium discoveries at Ramsay 1 and Ramsay 2, integrating 2D seismic data and detailed subsurface analysis to identify new high-priority zones. The campaign will also gather crucial well test data to inform the design of potential pilot-scale hydrogen and helium production systems.
Neil McDonald, Managing Director, said:
It’s an exciting step forward for Gold Hydrogen and for Australia’s clean energy future,
“With Ramsay 3 now drilling, we are moving from exploration success to proof-of-concept — laying the groundwork for potential commercialisation of natural hydrogen and helium in South Australia.”
The Ramsay 3 well features an enlarged 7-inch casing for increased flexibility in well testing and data collection. Following Ramsay 3, the Company plans to drill one or two additional wells in close proximity, progressing toward a pilot development area pending positive results.
Gold Hydrogen believes the Ramsay Project could represent one of the largest combined natural hydrogen and helium resources globally. Both gases have exceptional commercial potential — with helium long-term bulk prices estimated up to USD 450 per thousand cubic feet, and hydrogen positioned as a critical clean energy vector for the global transition.
The company’s portfolio now covers more than 75,000 km² of granted and pending exploration permits across South Australia, with ongoing engagement across local communities, landholders, and traditional owners.

ASX Announcement
Drilling Commences at Ramsay 3
Highlights:
The Company’s 2025 / 26 drilling and well testing campaign has now commenced with the spudding of the Ramsay 3 exploration well.
The 2025 / 26 work program is designed to:
• delineate and confirm the presence and scale of Natural Hydrogen and Helium across other parts of the exploration lease (PEL687), based on 2D seismic and the successful findings at Ramsay 1 and 2 wells;
• provide optimal conditions for well testing and extracting Natural Hydrogen and Helium to surface;
• mature the Ramsay Project via further appraisal in preparation for potential
commercial development decisions; and
• assist with the development of a blueprint for future exploration and appraisal initiatives across the Company’s wider portfolio.
The Directors of Gold Hydrogen Limited (Gold Hydrogen, ASX: GHY, the Company) are pleased to advise that the Company’s 2025 drilling campaign is underway with the spudding of the Ramsay 3 well at approximately 10:00am South Australian time this morning.
As outlined in its previous ASX release of 14 October 2025, the Company is planning to drill two or three wells as part of this campaign to appraise specific target zones within identified structures, chosen with reference to the results of the maiden drilling and testing campaign, as well as the interpretations leading from the 2D seismic survey conducted in the second half of 2024.
The primary objectives for the 2025 drilling program are to:
1. delineate and confirm the presence of Natural Hydrogen and Helium beyond the successful Natural Hydrogen and Helium gas shows at the Company’s Ramsay 1 and 2 wells;
2. provide optimal conditions for well testing and extracting Natural Hydrogen and Helium to surface;
3. mature the Ramsay Project via further appraisal in preparation for potential commercial development decisions; and
4. assist with the development of a blueprint for future exploration and appraisal initiatives across the Company’s wider portfolio.
Subject to the results of the Ramsay 3 drilling, a further one or two wells are planned for this drilling campaign. These will be in relatively close proximity to Ramsay 1, 2 and 3 with a view toward establishing a pilot project in this area, subject to results.
The well design for the 2025 / 26 campaign includes a larger diameter well bore with 7” casing to enable greater flexibility for well testing. The data expected to be gathered from the drilling and testing of the wells in the Company’s 2025 / 26 program will inform potential future pilot project
area(s) and design(s), with the aim of demonstrating the commercial production potential of both Natural Hydrogen and Helium from the Ramsay Project.
The Company will inform the market of any material developments during the drilling campaign.
General Commentary
First Key Step on the Journey to Future Commercialisation
Gold Hydrogen is of the view that the Ramsay Project contains significant prospective resources of both Natural Hydrogen and Helium, with large scale potential that the Company is aiming to commercialise over time.
There is very little data available for dedicated Hydrogen wells anywhere in the world due to the lack of analogue wells. Accordingly, there is inherent uncertainty with regard to the expected outcomes of the Company’s planned activities.
To the Company’s knowledge, the only Natural Hydrogen field currently in production is located in Mali, West Africa, where Natural Hydrogen production is used to power the small town of Bourakebougou. It has been reported that the Natural Hydrogen wells in Mali do not have any decline in production and are continually regenerating and producing at the same rate.
1 Helium is extremely valuable and indicatively, longer-term bulk pricing is expected to be up to USD450 per Mcf (thousand cubic feet). 2 Natural Hydrogen has a high energy content, and extracting it even in small quantities may prove commercial for localised applications. Furthermore, given that Helium was also found within both the Ramsay 1 and Ramsay 2 wells, being able to extract and process both gases in small quantities may
provide potential short-term commercial and / or proof of concept opportunities to help progress the Ramsay Project.
Important Risk Commentary
It is important to note that there remain both geological and potential development risks associated with the Ramsay Project and the Company’s commercial and business objectives. These risks relate to the presence, recovery and potential volumes of both Hydrogen and Helium, but also due to the location of the resource within agricultural areas and the proximity to National Parks on both Yorke Peninsula and Kangaroo Island, requiring significant landholder and community engagement. The worldwide, Federal and South Australian Government and industry efforts to secure Hydrogen as an alternative energy source provides confidence that any technical and social concerns may be overcome.
