Project summary description:
Gold Hydrogen holds Petroleum Exploration Licence (PEL) 687, which covers large sections of Yorke Peninsula and Kangaroo Island in South Australia.

PEL 687 covers known occurrences of natural hydrogen on Yorke Peninsula (and Kangaroo Island) which were discovered during the 1920s and 1930s during hydrocarbon exploration activities, including at the Minlaton Oil Syndicate Bore 1 (also known as Ramsay Oil Bore 1) east of Minlaton

A draft Environmental Impact Report (EIR), prepared in May 2023 under the Petroleum and Geothermal Energy Act 2000, addresses an exploration well drilling and testing program for natural hydrogen in the Yorke Peninsula component of PEL 687 planned to be undertaken by Gold Hydrogen.

Over the five-year span of the EIR and the accompanying Statement of Environmental Objectives (SEO), Gold Hydrogen expects to drill approximately five exploration wells and expects to acquire up to 600 kilometres of new 2D seismic data. The number and location of the wells would depend on drilling and testing results as the exploration program progresses.

Important early-stage site characterisation efforts undertaken prior to exploration drilling include (but are not limited to):

  • In March 2023, announcement of completion of its 2D seismic quality improvement workflow that commenced in August 2021.
  • In July 2023, announcement that CSIRO had undertaken an experimental Stage 1 soil gas testing survey on Yorke Peninsula with the aim of determining whether hydrogen gas is detectable in soils at surface.
  • In August 2023, announcement that the interpretation of the previously acquired airborne survey data has been received.
  • In September 2023, announcement updating on the (then) recently completed source/reservoir and seal rock characterisation studies on legacy well samples and available historical core material from within PEL 687.

In October 2023, Gold Hydrogen announced that the South Australian Government Department of Energy and Mines had approved the drilling of the Ramsay 1 well on the Yorke Peninsula and that drilling would commence within 24 hours. Within the announcement, the Company notes:

  • That the primary objective of the Ramsay 1 well is to confirm the presence of hydrogen in the subsurface geologic formations, by replicating the identification of hydrogen gas (up to 89% on an air-corrected basis) encountered during the drilling of the historic Ramsay Oil Bore 1 back in 1931, and to also more broadly confirm geological modelling based on the exploration data obtained during the past year.
  • It is expected to receive final Governmental approval for drilling its optional second well, Ramsay 2; the final timing and location for the drilling of Ramsay 2 will be contingent on the findings from Ramsay 1.
  • It is important to note that there are both geological and potential development risks associated with the Ramsay Project, including (though not limited to) risks relating to the presence, producibility and potential volumes of hydrogen.
