Announcement PDF 5 September 2023 ASX Announcement Appointment of Chief Exploration Advisor Highlights:  Frank Glass appointed Chief Exploration Advisor.  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 advise of the appointment of Frank Glass as the Company’s Chief Exploration Advisor. Mr Glass is an accomplished geologist and geoscientist who has been working in the petroleum and energy resources sector for well over 30 years, including a decade spent with Shell. Mr Glass has been part of the growing industry exploring for natural hydrogen since 2001, and has most recently served as the Exploration Manager at 2H Resources, leading a dynamic team in the pursuit of natural hydrogen opportunities within South Australia. Mr Glass has been involved with the establishment of a robust natural hydrogen exploration framework, including identifying high-potential regions for natural hydrogen prospects. This experience is expected to be of considerable benefit to Gold Hydrogen. Mr Glass has also been a driving force behind the inception of the Natural Hydrogen Association of Australia (NH2A), a national organization dedicated to supporting and advocating for the natural hydrogen exploration and development sector in Australia. Mr Glass holds a Masters Degree in Structural Geology from the University of Amsterdam, and holds numerous professional memberships including the Petroleum Exploration Society of Australia and the European Association of Geoscientists and Engineers, amongst others. Gold Hydrogen Managing Director, Neil McDonald, said: “We are excited to have someone with Frank’s geological experience and expertise in Natural Hydrogen working with us to help make our upcoming drilling program a success for the Company. Frank will also be heavily involved in the identification and planning for our future exploration leads and activities moving forward. On behalf of Gold Hydrogen, I am delighted to welcome Frank to the team.” 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. Gold Hydrogen Limited, Level 14, 110 Eagle Street (GPO Box 801) Brisbane, Qld 4000 | info@goldhydrogen.com.au | ABN 74 647 468 899 |1 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. The Company is currently progressing the planning and permitting for its maiden drilling campaign at its flagship Ramsay Project (refer PEL 687 on the Location Map) which hosts a prospective resource (refer Table 1) which the Company will be aiming to progressively expand and mature with its exploration activities.

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.
