Constellation Resources Ltd (ASX:CR1) has unveiled the significant natural hydrogen (NatH₂) potential at its Edmund-Collier Project in Western Australia following the reprocessing of historical seismic data and the final batch of Total Organic Carbon (TOC) results. This project marks the first substantial effort to explore for natural hydrogen in a vast, underexplored basin yet to witness deep drilling activity. The Edmund-Collier Project encompasses 37,288 square kilometers and exhibits promising organic-rich formations extending across the basin, suggesting strong potential for large-scale natural hydrogen generation. The company is set to conduct a basin-wide soil gas survey to detect potential hydrogen microseepage. The reprocessed seismic data has provided enhanced geological clarity in the basin, highlighting key formations, structural targets, and elements necessary for a viable natural hydrogen system. The project area contains all essential components for NatH₂ production, including suitable source rocks, migration pathways, reservoir rocks, sealing units, and structural traps. The presence of high Total Organic Carbon values and variable but locally strong porosity measurements further support the potential for viable hydrogen storage reservoirs. The Edmund-Collier Basin offers favorable conditions for thermogenic hydrogen generation, with thermal maturity levels meeting the requirements for hydrogen production. The basin's underexplored nature, particularly the Wanna Syncline, presents a new frontier for natural hydrogen exploration in Western Australia. Future plans involve a basin-wide soil gas survey to detect microseepage of hydrogen and helium, aiming to enhance understanding of hydrogen generation potential in the region.
