Prominence Energy Sets Mid-2027 Drilling Target with $5m Cost-Efficient Program

Clear Roadmap to Drilling in South Australia

Prominence Energy Limited (ASX:PRM) has carved out a methodical and capital-conscious pathway to progress its helium and natural hydrogen portfolio in South Australia toward drilling scheduled for June or July 2027. The company’s approach hinges on building a robust pipeline of defined leads and prospects through detailed geophysical data analysis before committing to costly drilling operations.

July’s focus centers on gravity and magnetic data inversion and interpretation, integrating these with existing geological and geochemical datasets to sharpen the technical definition of its acreage. This phase aims to crystallise the most prospective areas for exploration, setting the stage for a drilling campaign that balances risk and reward.

Independent Reviews to Quantify Resource Potential

Prominence plans independent Prospective Resources Reviews for its two principal projects: the Eyre Project by the end of August and the Northern Hinge Project by the end of September 2026. These assessments are designed to estimate the scale of exploration opportunities and provide a foundation for technical and commercial decisions ahead of drilling.

These projects form part of a substantial 64,000 km² South Australian portfolio, where previous work has already identified multiple helium and natural hydrogen anomalies, including those confirmed through soil gas surveys and laboratory analysis. This growing body of evidence supports the company’s exploration model and underpins its planned advancement toward drilling.

Cost Discipline and Drilling Planning

Following the resource reviews, Prominence will update its drilling engineering and cost estimates in October. Preliminary figures suggest the company could drill three exploration wells or two wells plus seismic data acquisition for approximately $5 million, a relatively modest sum given the shallow target depths. This cost-efficient program offers multiple opportunities to unlock value while limiting capital exposure.

Detailed design and planning for the 2027 drilling campaign are slated for November and December, with a clear emphasis on targeting the highest-ranked prospects. Prominence’s strategy includes a disciplined technical and financial framework to ensure drilling is both purposeful and cost-effective.

Strategic Partnerships to Mitigate Capital Risk

As the portfolio matures into a defined set of prospects, Prominence intends to explore farm-out or strategic partnership opportunities to share the financial burden of drilling. This approach aims to attract third-party validation and funding while allowing Prominence to retain meaningful upside exposure.

Chief Operating Officer Dr Krista Davies emphasised the company’s measured approach: “We are using relatively low-cost work to build the strongest possible technical and commercial case before finalising our 2027 drilling program.” This staged progression offers a sequence of potential value catalysts, from exploration data to resource estimates and partnering discussions, culminating in a drilling program designed to maximise shareholder value.

Capital Efficiency at the Forefront

Prominence’s capital-efficient strategy builds on earlier work, including soil gas surveys, laboratory analyses, and satellite studies, which have helped derisk drill targets without large expenditures. The company’s existing cash reserves cover the 2026 exploration and planning activities, positioning it well to advance without immediate capital raises.

This careful calibration of technical progress and financial discipline places Prominence in a strong position to unlock the value of its South Australian helium and natural hydrogen projects, with a clear timeline and cost framework guiding the journey to drilling.
