Ramsay Helium Flow Test Campaign Completed

• Completed Helium flow testing across three Ramsay wells in under three months
• Confirmed a large, connected, and highly productive Helium reservoir
• Achieved up to 14,000 bbl/day pumping rate at Ramsay 3
• Targeting maiden Contingent Resource sign-off in November 2026
• Accelerating planning for a staged, modular Helium pilot

Gold Hydrogen Limited has successfully completed the Ramsay Helium flow test campaign, confirming the presence of a large, connected, and highly productive Helium-bearing reservoir. Key highlights include: Helium flow testing across all three Ramsay wells in under three months with no lost time injuries or safety incidents, Helium successfully bottled onsite for the first time in Australia since 2023, and scaled pumping rates up to approximately 14,000 barrels per day at Ramsay 3, the highest rate achieved to date. The results indicate a Helium-bearing Kulpara Dolomite reservoir spanning approximately 2.2 kilometers with sustained air-corrected Helium concentrations averaging approximately 15.2%. This is significantly higher than the 1% concentration typical of global commercial Helium projects. The Company is accelerating planning for a staged, modular Helium pilot designed to leverage existing Ramsay wells, potentially reducing upfront capital requirements and shortening the pathway to initial production. The Company is targeting a maiden Contingent Resource sign-off in November 2026.
