Announcement PDF 3 July 2025 ASX Announcement Toyota Motor Corporation, Mitsubishi Gas Chemical and ENEOS Explora Confirmed as Strategic Investors Gold Hydrogen Limited (ASX: GHY) (“Gold Hydrogen” or “the Company”) is pleased to announce that it has received binding commitments for a total investment of $14.5 million from Toyota Motor Corporation Hydrogen Factory, Mitsubishi Gas Chemical, and ENEOS Explora into Gold Hydrogen. The investment will be through a placement of 20,714,285 fully paid ordinary shares at $0.70 per share, representing a premium of 22% to the Company’s last closing price of $0.575 on the ASX on 2 July 2025. Following an extensive seven-month due diligence process, which attracted significant interest from numerous international groups, Gold Hydrogen selected these three global leaders as key strategic investors based on their innovation and leadership in hydrogen, helium, energy and transport technologies. This investment followed the prior publication of the Company’s significant results from the Stage 1 drilling of its small-diameter exploration wells, Ramsay-1 and Ramsay-2, which confirmed an active hydrogen and helium system, with results including up to 95% natural hydrogen purity 1, up to 36.9% helium purity 2, and elevated levels of helium-3 3, within the Ramsay Project (PEL687), Yorke Peninsula, South Australia. These outstanding results provided the platform for the Company’s international strategic partnering process, working in conjunction with Morgans Financial and Mizuho Securities, as previously advised to the market on 31 March 2025. Upcoming Exploration Program The proceeds of this strategic investment will fund further drilling in the Ramsay fairway leveraging the results from the Company’s maiden drilling and well testing campaigns at Ramsay-1 and Ramsay-2, and will help to advance future downstream / commercialisation opportunities for the Ramsay Project. The drilling program, which is expected to commence in Q4, 2025, has been designed to further delineate and appraise the Ramsay Project’s natural hydrogen and helium accumulations, through appraisal well drilling and a range of testing activities.

In addition to the upcoming field activities at the Ramsay Project, the parties will consider the potential for further investment opportunities, technical collaboration, downstream opportunities and offtake arrangements. A Working Group will be formed to advance feasibility studies, as well as the opportunities associated with technical collaboration arrangements, downstream project and / or investment opportunities and potential future offtake arrangements. Gold Hydrogen Chairman and Management Commentary Gold Hydrogen’s Managing Director Neil McDonald commented: “This is a landmark moment for our Company. Partnering with world-renowned leaders like Toyota Motor Corporation, Mitsubishi Gas Chemical and ENEOS Xplora validates the global significance of Gold Hydrogen’s natural hydrogen and helium potential. Together, we will be aiming to ultimately unlock a new era of sustainable, low-emissions hydrogen and helium production at scale. “We look forward to a long-term relationship with such respected partners. This collaboration opens the door to a range of potential domestic and international clean energy solutions upstream and downstream.” Gold Hydrogen’s Chairman Alexander Downer AC commented: “Australia and Japan have had a very long and symbiotic relationship involving trade and investment in the energy sector. The Japanese Government has announced energy policies aimed to achieve carbon neutrality and the reduced use of fossil fuels. In particular, Japan is actively pursuing a hydrogen-based society with a robust hydrogen supply chain for various applications, including generation, fuel cells and transportation. “We at Gold Hydrogen look forward to working with our strategic investors - Toyota, Mitsubishi Gas Chemical, and ENEOS with the aim of ultimately commercialising the Ramsay Hydrogen and Helium project and leveraging our combined expertise.” Gold Hydrogen Limited, Level 14, 110 Eagle Street (GPO Box 801) Brisbane, Qld 4000 | info@goldhydrogen.com.au | ABN 74 647 468 899 Financial Settlement and Next Steps Settlement of the placement and allotment of the shares is expected to occur as outlined in the Table below, with the shares to be issued under the Company’s existing placement capacity.

Link: https://investorhub.goldhydrogen.com.au/webinars/LPZggy-gold-hydrogen-july-webinar About Gold Hydrogen Gold Hydrogen is focused on the discovery and development of world class Natural Hydrogen and Helium gases in a potentially extensive province in South Australia. This region has recently had its Natural Hydrogen and Helium potential confirmed by the Company via its maiden drilling campaign. The domestic and global demand for Hydrogen and Helium, combined with new exploration techniques and experienced personnel, provides Gold Hydrogen with an extraordinary opportunity to define and ultimately develop a new Natural Hydrogen and Helium gas province. The combined permit area of the Gold Hydrogen group is now in excess of 75,000km2. Gold Hydrogen holds one granted exploration license (the Ramsay Project - PEL 687) and one application area, whilst its two 100% owned subsidiary companies (White Hydrogen Australia and Byrock Resources) hold an additional seven (7) applications for Natural Hydrogen and Helium exploration within South Australia. Gold Hydrogen is also the preferred applicant for four (4) gas storage exploration licenses applications (GSELA) covering an area of approximately 8,000km2 within the Yorke Peninsula portion of PEL 687 in South Australia. The group’s permit areas are characterised by low population densities, cooperative stakeholders and aspects of the natural environment suited to the exploration and development of a future Natural Hydrogen and Helium gas province. Gold Hydrogen places considerable importance on close liaison with landholders, traditional owners and all other stakeholders, and this approach has led to the grant of its key tenement PEL 687 in South Australia. The Company intends to continue to invest in these efforts.
