• Sizeable 87,602km2 natural hydrogen project area across Western Australia
• Reprocessed seismic data indicates potential for large-scale natural hydrogen generation
• Encouraging total organic carbon results from diamond drilling in Edmund-Collier Basin

Constellation Resources Ltd has provided its Quarterly Report for the period ended 30 June 2025. The company's focus is on its projects in Western Australia, including its natural hydrogen projects covering a sizeable 87,602km2 area across the Edmund-Collier, Yerrida and Ashburton Basins. During the quarter, the company completed reprocessing and interpretation of a historical Geoscience Australia seismic line, which indicated that the organic-rich Blue Billy and Discovery Formations extend across the Edmund-Collier Basin and may be capable of generating large-scale natural hydrogen. Total organic carbon (TOC) results from eleven diamond holes in the Edmund-Collier Basin also demonstrated strong values, with some exceeding 5%, considered excellent for potential natural hydrogen production. The company continues to collaborate with the CSIRO to advance prospectivity studies for natural hydrogen and helium across its projects. At the Ularring Copper Gold Project, the company's maiden Ultrafine+TM soil program identified a strong geochemical 1.3km x 0.45km gold-copper anomaly called Chatham, which exhibits associated elements typical of known copper-gold mineralization in the area. Chatham is located over the prospective Meenar Shear and overlies a historical VTEM anomaly, indicating potential for a conductive sulphide-rich target. The company is progressing stakeholder engagement and plans to commence ground activities for its natural hydrogen projects upon finalizing approvals.

The company continues to evaluate new business opportunities in the resources sector, both domestically and overseas, but no agreements have been reached or licences granted at this time.
