Prominence Energy Plans Three Well Helium and Hydrogen Program for $5M
Prominence Energy has outlined a staged, capital-efficient pathway to advance its South Australian helium and natural hydrogen portfolio toward drilling in June/July 2027. The company announced preliminary costings suggest potentially three wells for approximately $5 million, or two wells plus seismic acquisition, with the 2026 program (including drill planning) fully funded by existing cash. The portfolio spans approximately 64,000 km² across South Australia.
The catalyst pipeline: what happens between now and drilling
Prominence has structured the coming months as a sequenced work program, with each stage designed to build technical definition and potential strategic value before drilling expenditure is committed.
| Timing | Activity | Purpose | Project(s) |
|---|---|---|---|
| July 2026 | Gravity & magnetic data inversion and interpretation | Build leads & prospects portfolio | All project areas |
| End of August 2026 | Independent Prospective Resources Review | Assess potential scale of exploration opportunities | Eyre Project |
| End of September 2026 | Independent Prospective Resources Review | Assess potential scale of exploration opportunities | Northern Hinge Project |
| October 2026 | Revised drilling engineering & cost review; commence farm-out process | Update well designs and cost estimates | Portfolio-wide |
| November–December 2026 | Design and planning of the 2027 drilling campaign | Direct drilling toward highest-ranked opportunities | Portfolio-wide |
The independent Prospective Resources Reviews are intended to provide an important foundation for future technical, commercial and funding decisions. Each step in the sequence represents a discrete potential value catalyst ahead of the planned mid-2027 drilling program.

Why helium and natural hydrogen matter
Prominence’s portfolio targets two emerging, high-value energy resources with distinct technical and commercial characteristics:
- Natural hydrogen (white or geologic hydrogen): Formed naturally underground through geological processes, identifiable via conventional low-cost non-invasive exploration methods, and represents a zero-carbon fuel producing only water vapour when combusted.
- Helium: A non-renewable noble gas generated through radioactive decay of uranium and thorium within ancient crustal rocks, particularly Archean granites. Essential applications include medical imaging, semiconductor manufacturing, space technologies and cryogenics. The resource is currently subject to global supply constraints.
The company has already generated multiple independent datasets supporting its exploration model at PEL 803, including field and laboratory-confirmed helium and natural hydrogen anomalies and widespread anomalies identified through independent satellite analysis, as detailed in ASX announcements from May and June 2026.
A disciplined, capital-efficient strategy
Prominence’s approach prioritises maximising information before committing significant drilling expenditure. The company has already deployed relatively low-cost exploration techniques to build its technical understanding:
- Soil gas surveys
- Independent laboratory analysis
- Satellite studies
- Existing geophysical datasets
The shallow nature of the targets underpins the approximately $5 million multi-well economics, providing what the company describes as a potentially attractive risk-versus-reward multi-opportunity drill program.
Dr Krista Davies, Chief Operating Officer
“This is a disciplined approach. We are using relatively low-cost work to build the strongest possible technical and commercial case before finalising our 2027 drilling program.”
The October drilling engineering and cost review is expected to refine these preliminary estimates further and provide updated information ahead of the detailed 2027 program design phase.

Farm-out optionality and the investment case
As the project portfolio becomes more clearly defined, Prominence intends to assess opportunities for farm-out, strategic partnership or other funding structures ahead of drilling. A successful partnering process could provide third-party validation of the project opportunity while reducing the company’s direct capital exposure to drilling.
The company has stated it will seek to retain meaningful exposure to exploration success while maintaining a disciplined approach to shareholder capital. The farm-out process is targeted to commence in October 2026, following completion of the prospective resources work and revised drilling cost assessment.
Prominence positions the coming months as a transition from emerging exploration story to defined prospect portfolio and planned drilling program, all within existing cash resources. The staged pathway preserves capital while maintaining significant exposure to exploration success across both the Eyre and Northern Hinge Projects, which form part of the company’s approximately 64,000 km² South Australian portfolio.
