Gold Hydrogen Ltd (ASX:GHY) is set to begin drilling the Ramsay 2 well at its flagship Ramsay natural hydrogen project in South Australia.
The company is mobilising contractors and company supervisors to the Ramsay 2 well site, with drilling operations on track to commence drilling in the next 24 to 48 hours.
The Ramsay 2 well is about 500 metres west of the Ramsay 1 well — the first dedicated natural hydrogen exploration well in Australia, which was completed on October 28, 2023.
The company’s technical objectives at Ramsay 2 will be similar to that of Ramsay 1 in terms of well depth and target formations, with a target depth of around 1,000 metres, subject to drilling conditions.
Ramsay 1 confirmed the presence of natural hydrogen in the Parara Limestone formation, recording an air-corrected measure of 73.3% purity hydrogen at a depth of 240 metres, along with detecting helium in the granite basement of 3.6% at 892 metres.
Ramsay 2 has been designed to further test these zones and is expected to take between 14 and 16 days to drill, depending on ground conditions. The well will be suspended for future well testing in conjunction with Ramsay 1.
“Potentially extensive natural hydrogen province”
Gold Hydrogen outlined the primary objectives of the Ramsay Project, from a technical perspective: to progress its natural hydrogen Prospective Resources to Contingent Resources and/or Reserves, which will involve the processes of discovery, appraisal and commercialisation; and to mature portions of the granted title PEL 687 to Production Licence areas.
The Ramsay Project is in a potentially extensive natural hydrogen province in South Australia. Natural hydrogen gas was recovered in three samples taken in Ramsay Oil Bore 1 drilled back in 1931, with the historical drilling encountering natural hydrogen at depths of 240.8 metres, 262.1 metres and 507.8 metres — all indicated as being within the Cambrian Parara Limestone.
Gold Hydrogen recognises the potential here to define and ultimately develop a new natural hydrogen gas province, supported by domestic and global demand for hydrogen, combined with new natural hydrogen exploration techniques and experienced personnel.
