• The Edmund-Collier Project represents a first-of-its-kind opportunity in Western Australia to explore for natural hydrogen across a large, underexplored basin
• Seismic interpretation indicates the organic rich Blue Billy and Discovery Formations may be capable of generating large-scale natural hydrogen
• Final batch of TOC results continue to demonstrate strong values across the entire basin, with any results over 2% considered good to excellent for potential NatH2 production

Constellation Resources Limited has completed reprocessing and interpretation of a historical Geoscience Australia seismic line 10GA-CP2 and received the final batch of Total Organic Carbon (TOC) results within its Edmund-Collier Natural Hydrogen Project. The Edmund-Collier Project represents a first-of-its-kind opportunity in Western Australia to explore for natural hydrogen across a large, underexplored basin, with no prior deep drilling to date. Cross section interpretation along the seismic line indicates the organic rich Blue Billy and Discovery Formations extend across the Edmund-Collier Basin and may be capable of generating large-scale natural hydrogen, given the source rock and thermal maturity analysis completed. The Godfrey and Talga Faults are both deep regional faults that extend from the basement to surface and provide ideal targets for surface soil gas sampling to test for potential surface gas seepage. The final batch of TOC results continue to demonstrate strong values across the entire basin, with any results over 2% TOC considered good to excellent for potential NatH2 production. Encouraging porosity values were also returned from various sedimentary formations. The Company plans to undertake a soil gas survey across its NatH2 portfolio to directly detect the potential presence for micro seepage of targeted gases in the following months.
