Constellation Resources Completes $3.2 Million Raise to Advance Natural Hydrogen Exploration in Western Australia

Constellation Resources has completed its Entitlements Offer and placed all remaining shortfall shares, raising the full A$3.2 million as the company prepares to advance natural hydrogen exploration across its Western Australian portfolio. 

The new funding puts Constellation in a stronger financial position to progress technical work at the Edmund Collier Project, where a series of near-term studies and field programs are intended to rank and substantiate exploration play types before the company moves toward higher-value exploration such as seismic surveys and drilling. 

One of the central workstreams is being carried out with CSIRO. 

Technical studies currently underway include an assessment of natural hydrogen prospectivity across the Edmund Collier Basin, alongside work at the Yerrida project examining the composition of trapped gases using publicly available core samples. 

Constellation is also undertaking detailed petrological and porosity studies using historical drill core held at the Perth Core Library. 

The systematic petrographic sampling program is being overseen by Dr Mark Partington and Iain Copp and is designed to provide additional information about the rocks and potential reservoir characteristics within the company’s exploration areas. 

Another important near-term program will be a regional soil-gas survey across Constellation’s recently granted SPA-AOs. 

The low-cost survey is designed to investigate whether gases migrating from potential subsurface accumulations can be detected as micro-seepage at surface. 

Constellation plans to collect measurements from shallow holes approximately 50 centimetres deep, positioned along existing tracks at spacing of roughly one to three kilometres. The program will also analyze open mineral drill-hole collars. 

Together, these programs represent a relatively low-cost exploration phase intended to narrow a much larger search area before more capital-intensive subsurface work begins. 

The project map included with the announcement highlights the scale of Constellation’s Edmund Collier position and identifies interpreted antiformal traps alongside major regional faults, existing infrastructure and the company’s exploration tenure. 

Several of those interpreted trap areas occur around SPA 048 AO and SPA 049 AO, while the broader project sits within a region crossed by significant structural features including the Talga Fault, Mt Vernon Fault and Deadly Creek Fault. 

Constellation is simultaneously progressing the regulatory and stakeholder work required across additional parts of the portfolio. 

The Environmental Plan and stakeholder engagement process for STP-SPA-0116 is nearing completion, with the company expecting a six-month work period to potentially be approved by the relevant department toward the end of 2026 or early 2027. 

Native title discussions are also underway for STP-SPA-0143. 

The A$3.2 million financing therefore arrives as Constellation moves from broad geological evaluation toward increasingly targeted natural hydrogen exploration. 

Rather than moving immediately into drilling, the company is using CSIRO prospectivity studies, historical core analysis, petrology, porosity work and regional soil-gas measurements to determine which geological plays warrant more expensive seismic and ultimately drilling programs. 

For Constellation, the next important step will be whether those programs can identify and rank convincing subsurface targets at Edmund Collier. 

With the Entitlements Offer now fully completed, the company has additional capital available to carry out that work and build the technical case for the higher-value exploration phase that could follow.
