Announcement PDF 9 August 2023 ASX Announcement Ramsay Project Airborne Survey Update Highlights:  Airborne survey geophysical interpretation received.  Results expected to enhance subsurface understanding for the distribution of natural hydrogen source rocks, subsurface structures, stratigraphy, and mature leads to prospects across the Ramsay Project.  Planning continues for the execution of the Company’s maiden drill program for the Ramsay Project, expected to commence in October 2023. The Directors of Gold Hydrogen Limited (Gold Hydrogen, ASX: GHY, the Company) are pleased to report that the interpretation of the previously acquired airborne survey data has now been received. As reported on 3 May 2023, the 10,529-line kilometre gravity-magnetic-digital terrain geophysical survey was flown by Xcalibur Multiphysics over the mainland Yorke Peninsula component of the Company’s flagship Ramsay Project (refer Location Map). The processed and interpreted airborne survey data has sharpened the imagery of the main structural boundaries, and is assisting the Company with the visualisation of the subsurface geology of the survey area. The combined gravity and magnetic data is also aiding in the detection of large-scale faults, estimated depths to basement, and the potential composition of the basement rocks. The data is an essential component for the subsurface model of where hydrogen may be coming from, as well as potential migration routes. Importantly, the data also supports the selection of the first well location. A sample of the suite of images from interpreted data is shown in Figure 1. The airborne survey interpretation will now be considered and analysed by the Gold Hydrogen team in conjunction with the various other datasets being compiled by the Company including the soil-gas survey results, the reprocessing and interpretation of historical seismic data, sub-surface static and dynamic modelling, and the legacy well data. In the short-term, this combination of geological and geophysical data will support the Company’s maiden drilling program, scheduled to commence in October 2023. With the drilling and testing results, the airborne survey data and interpretation are expected to play an important role in the delineation of the potential hydrogen discovery, and with the identification of additional plays, leads and ultimately future drill hole locations.

Ramsay Project Objectives From a technical perspective, the primary objectives of the Ramsay Project are to: (i) progress its natural hydrogen Prospective Resources to Contingent Resources and/or Reserves. This will involve the processes of discovery, appraisal and commercialisation; and (ii) transfer portions of the granted title PEL 687 to Production Licence. Gold Hydrogen Limited, Level 14, 110 Eagle Street (GPO Box 801) Brisbane, Qld 4000 | info@goldhydrogen.com.au | ABN 74 647 468 899 |2 Historically, natural hydrogen gas was recovered in three samples taken in Ramsay Oil Bore 1 drilled in 1931. The samples were taken at depths of 240.8m, 262.1m and 507.8m, all indicated as being within the Cambrian Parara Limestone. The Company’s Prospective Resource Statement is outlined in Table 1 below. The first exploration well to be drilled by Gold Hydrogen (Ramsay 1) is being designed and located to verify the findings of the historic Ramsay Oil Bore 1 in order to mature the historical occurrences of natural hydrogen to a ‘discovery’ for resource evaluation and reporting purposes. Exploration wells need to be drilled, evaluated and tested to determine the presence, producibility, extent and thus ‘discovery’ of hydrogen from the geological reservoirs. It is important to note that there are both geological and potential development risks associated with the Ramsay Project and the Company’s objectives as outlined above. These risks relate to the presence, producibility and potential volumes of hydrogen, 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, National 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. About Gold Hydrogen Gold Hydrogen is focused on the discovery and development of world class natural hydrogen gas in a potentially extensive natural hydrogen province in South Australia. This region has only recently had its natural hydrogen potential identified by the Company. The domestic and global demand for hydrogen, combined with new natural hydrogen exploration techniques and experienced personnel, provides Gold Hydrogen with an extraordinary opportunity to define and ultimately develop a new natural hydrogen gas province. The combined natural hydrogen permit area of the Gold Hydrogen group is approximately 75,332km2. Gold Hydrogen holds one granted petroleum exploration license (the Ramsay Project - PEL 687) and its two 100% owned subsidiary companies (White Hydrogen Australia and Byrock Resources) hold an additional seven (7) applications for natural hydrogen exploration within South Australia. Gold Hydrogen is also the preferred applicant for four (4) gas storage exploration licenses applications (GSELA) covering an area of 8,107km2 within the Yorke Peninsula portion of PEL 687 in South Australia. These storage licence applications are in addition to the granted exploration licence and application licences.

It should be noted that the estimated quantities of Natural Hydrogen that may potentially be recovered by the application of a future development project(s) relate to undiscovered accumulations. These estimates have both an associated risk of discovery and a risk of development. Further exploration, appraisal and evaluation is required to determine the existence of a significant quantity of potentially recoverable Natural Hydrogen. The Company confirms that it is not aware of any further new information or data that materially affects the estimates of Natural Hydrogen Prospective Resources (as originally estimated on 30 September 2021), and that all material assumptions and technical parameters underpinning the estimates continue to apply and have not materially changed.
