Key Highlights

  • A CSIRO study detected hydrogen in fluid inclusions in all 28 rock samples analysed from the Eyre area.
  • Independent prospective resources for Eyre total 202.8 billion cubic feet of natural hydrogen across 15 leads, unrisked.
  • Cash was $1.38 million at 30 September with an estimated 3.6 quarters of funding, including a $60,000 undrawn standby arrangement.
  • The first multi-well drilling campaign is targeted for mid-2027, subject to permit grant and funding.

Prominence Energy (ASX:PRM) is an early-stage explorer focused on natural hydrogen, helium and associated gases in South Australia's Gawler region, through its Eyre Project and the Northern Hinge exploration applications. Over the past two months it has released a series of technical studies intended to rank targets for a first multi-well drilling campaign, which it is targeting for mid-2027.

The common thread is that Prominence is still building its exploration case rather than testing it. Its latest release, on 4 November 2026, reported a CSIRO study that detected hydrogen in fluid inclusions in all 28 rock samples analysed from the Eyre area. That is evidence of past hydrogen-bearing fluids, not a discovery of a gas accumulation, and the company says it will use the results to help select drilling targets.

Prospective resources, not reserves

On 14 September 2026 the company reported an independent assessment by RISC Advisory that assigned the Eyre Project gross unrisked 2U Prospective Resources of 202.8 billion cubic feet of natural hydrogen and 9.2 billion cubic feet of helium across 15 leads. On 22 October 2026 it reported its own assessment for Northern Hinge of about 4 trillion cubic feet of hydrogen, 102 billion cubic feet of helium and 320 billion cubic feet of petroleum gas across 28 leads; the company says this is subject to independent technical audit by RISC.

Prospective resources are estimated quantities that might be recovered from undiscovered accumulations. They are unrisked, carry no confirmation that gas exists, and should not be read as reserves or contingent resources. Natural hydrogen is also a young exploration field with few commercial precedents.

Tenure and approvals

According to the September quarter activities report released on 30 October 2026, the company executed a native title Indigenous Land Use Agreement covering about 19,889km² of Northern Hinge exploration permit applications during the quarter. Those areas remain applications, so grant is still a step to be cleared. The company also completed gravity and magnetic inversion work across Eyre and Northern Hinge.

Cash and capital structure

The September quarter Appendix 5B shows cash of $1.38 million at 30 September 2026, net operating outflows of $235,000 and exploration spending of about $90,000 recorded as investing. The company estimated 3.6 quarters of funding, a figure that includes a $60,000 undrawn Credit standby arrangement.

Prominence has about 2.7 billion shares on issue. On 8 October 2026 it applied for Quotation of 32.2 million shares issued from exercised Options or converted securities. Funding a multi-well drilling programme would likely require new capital or a farm-out partner, which the company says it is pursuing.

Board changes and risks

Chair Ian McCubbing retired on 31 October 2026, with Bevan Tarrant becoming Non-Executive Chairman, according to the company's 7 October announcement. Director Troy Hayden intends to retire at the AGM and be replaced by geophysicist Chris Lewis.

Key risks include the absence of any drilling to date, the speculative nature of natural hydrogen as a commodity, permit grant timing at Northern Hinge, the need to fund drilling, and the dilution that Equity funding at current prices could bring. The Northern Hinge estimate has not yet been independently audited.

What to watch

The Annual General Meeting is scheduled for 1.30pm (AWST) on 30 November 2026 in Perth. Other milestones include the RISC audit of the Northern Hinge figures, grant of the Northern Hinge applications, any farm-out agreement, and progress towards the mid-2027 drilling target.
