Prominence Energy targeting mid-2027 drilling for much-needed helium and hydrogen

• Gravity and magnetic inversion and interpretation completed across the Eyre and Northern Hinge projects
• Results confirm key elements of geological model
• Studies strengthening previously identified structural leads and identifying new targets
• Independent Eyre project prospective resources review underway

Prominence Energy (ASX:PRM) has identified new targets to follow-up for its first drilling program targeting natural helium and hydrogen in South Australia in mid-2027.

The company has hit another scheduled technical milestone with the completion of a major gravity and magnetic inversion and interpretation completed across the Eyre and Northern Hinge projects.

COO, Dr Krista Davies, said the results have confirmed key elements of the company’s geological and identified some new targets to follow-up.

“We are continuing to tick the boxes towards drilling. The completed geophysical work confirms much of our existing interpretation, strengthens several leads and has identified new opportunities across Eyre and Northern Hinge,” Dr Davies said.

“With the Eyre prospective resources review now underway and Northern Hinge advancing, our focus is on ranking the best drilling opportunities and maintaining momentum towards a disciplined mid- 2027 drilling campaign.”

The gravity and magnetic interpretation study covered both the Eyre and Northern Hinge areas and used existing gravity and magnetic datasets to refine subsurface structure, geological boundaries and stratigraphic architecture relevant to helium and natural hydrogen accumulation.

The study involved reprocessing and interpretation of available gravity and magnetic datasets to improve Prominence’s understanding of subsurface structures, geological boundaries and stratigraphic architecture that may influence the generation, migration and accumulation of helium, natural hydrogen and associated gases.

RISC Advisory has commenced an independent prospective resources review of the Eyre project, targeted for completion by the end of this month.

The review will assess the potential scale of identified exploration opportunities and provide an independent basis for subsequent technical, commercial and drilling decisions.

The Eyre exploration model is supported by multiple datasets. These datasets, together with the completed geophysical work, will underpin the resource review and ongoing prospect ranking.

Meanwhile, Prominence continues to build the Northern Hinge prospects and leads portfolio following finalisation of the Native Title Land Use Agreement

The agreement supports the pathway towards grant of approximately 20,000 sq. km of prospective acreage and enables the next phase of technical work and prospect definition.

Current work is focused on refining existing leads, assessing newly identified leads and preparing the portfolio for an independent prospective resources review targeted for September 2026.

PRM is steady at 0.2¢. Mkt cap $4.013M.
