Overview of Prominence Energy's South Australian Helium and Hydrogen Assets
Prominence Energy Limited manages an extensive approximately 64,000 square kilometre portfolio in South Australia, concentrating on helium and natural hydrogen exploration. The company's core projects—the Eyre Project and the Northern Hinge Project—cover significant exploration acreage within a region showing emerging potential for helium and hydrogen resources. These projects underpin the company's exploration strategy and are the focal points of current technical efforts and upcoming drilling campaigns.
The exploration approach is supported by multiple independent datasets compiled during the first half of 2026. Prominence has identified helium and natural hydrogen anomalies confirmed by fieldwork and laboratory analysis, alongside widespread anomalies detected through independent satellite studies. The integration of geochemical data, laboratory results, and satellite information has reinforced the technical case for helium and hydrogen across the South Australian portfolio. This multidisciplinary exploration methodology positions the portfolio for the next stage of technical development and potential resource evaluation.
July 2026 Geophysical Data Inversion and Lead Identification Plan
In July 2026, Prominence is conducting gravity and magnetic data inversion and interpretation across its project areas. This geophysical work is essential for transforming existing exploration evidence into well-defined leads and prospects suitable for prospective resource assessment and drilling evaluation. The company is integrating these geophysical interpretations with existing geological, geochemical, laboratory, and satellite datasets to pinpoint and delineate the most promising exploration targets.
The primary goal is to build a robust portfolio of defined leads and prospects throughout the acreage. By methodically processing gravity and magnetic data—cost-effective exploration techniques relative to drilling—Prominence aims to de-risk potential drill targets and enhance the technical clarity of its projects. This disciplined capital management strategy focuses expensive drilling investments only on prospects with strong technical foundations and clear exploration objectives.
Independent Prospective Resources Assessments for Eyre and Northern Hinge Projects
Prominence has scheduled independent Prospective Resources Reviews for both major project areas to evaluate the scale of identified exploration opportunities. The Eyre Project review targets completion by the end of August 2026, while the Northern Hinge Project review aims for the end of September 2026. These independent evaluations will form a critical basis for future technical decisions, commercial assessments, and funding discussions related to the portfolio.
These prospective resources reviews mark a significant milestone in the company’s value creation process. By securing independent, professional assessments of potential resource scale at both projects, Prominence seeks to strengthen the technical and commercial rationale for its exploration programs and provide investors and prospective partners with transparent, third-party validation of project potential. The reviews are expected to guide subsequent drilling decisions and may enhance the company’s appeal to strategic partners or co-investors interested in farm-out or joint venture arrangements.
Drilling Engineering Assessment and Initial Cost Projections for 2027
After completing the prospective resources assessments, Prominence plans an updated drilling engineering and cost review in October 2026. This review will refine well designs and provide current cost estimates ahead of detailed planning for the 2027 drilling program. The assessment aims to optimize drilling strategies based on the latest technical insights and maximize exploration value through well placement.
Preliminary cost estimates indicate that approximately three exploration wells or two wells plus seismic data acquisition can be completed for around $5 million. This cost-effective scenario reflects the shallow nature of helium and hydrogen targets within the South Australian portfolio. The October drilling engineering review will further refine these estimates and offer more precise cost guidance. This flexible multi-well, multi-option approach offers Prominence a compelling risk-reward drilling program adaptable to exploration results and technical findings.
Comprehensive 2027 Drilling Program Planning and Design Timeline
In November and December 2026, Prominence will concentrate on detailed design and planning for the 2027 drilling campaign. The goal during this phase is to ensure drilling targets the highest-priority exploration opportunities with clear technical objectives and cost discipline. This final planning stage completes the company’s phased de-risking strategy and sets the stage for mid-2027 drilling operations.
This disciplined drilling preparation underscores Prominence’s commitment to capital efficiency and maximizing exploration success probability. By conducting multiple rounds of technical work, resource assessments, and engineering reviews before finalizing drill sites and well designs, the company focuses drilling expenditures on the most promising targets. The November-December planning will integrate all prior technical findings, incorporate independent prospective resources review results, and deliver a detailed operational plan for the 2027 drilling program.
Farm-Out and Strategic Partnership Opportunities to Minimize Capital Outlay
As the portfolio becomes better defined through ongoing work programs, Prominence plans to explore farm-out, strategic partnership, or alternative funding options ahead of drilling. Successful partnerships could offer third-party validation of project potential while lowering Prominence’s direct capital exposure to drilling costs. The company intends to maintain meaningful exposure to exploration upside while adhering to prudent capital deployment.
The farm-out and partnership approach is a key component of Prominence’s capital-efficient strategy. By attracting external partners or investors to co-finance drilling, the company can reduce financial risk and benefit from partner expertise, operational capabilities, and market insights. This strategy also provides independent validation, as partners conducting technical due diligence implicitly endorse the geological and geochemical basis of the exploration case. Prominence’s pursuit of such arrangements demonstrates flexibility in structuring project development while preserving significant equity and upside for existing shareholders.
Sequence of Upcoming Value Catalysts Leading to Drilling
Prominence’s strategy revolves around a series of potential value catalysts for shareholders. The company plans to advance through defined milestones: gravity and magnetic data interpretation and lead definition in July; independent Prospective Resources Reviews by end-August and end-September; updated drilling engineering and cost review in October; and detailed drilling program design and planning in November and December. Each milestone aims to progressively enhance technical definition and strategic value before committing to drilling expenditures.
The company emphasizes these work programs as creating a "clear sequence of potential catalysts for shareholders." This phased approach ensures investors receive regular technical updates and progress indicators instead of a single concentrated expenditure event. By progressing from exploration evidence to defined prospects, resource estimates, partnering opportunities, and ultimately drilling, Prominence offers shareholders multiple assessment points on project progress and company strategy. This transparent milestone delivery strengthens communication between management and investors regarding development and risk management.
Capital-Efficient Exploration Through Low-Cost Pre-Drilling Techniques
Prominence’s approach prioritizes maximizing information before significant drilling investment. The company has employed cost-effective techniques such as soil gas surveys, laboratory analysis of geological samples, satellite studies, and evaluation of existing geophysical data to build technical understanding. These methods have enabled effective de-risking of drill targets and development of a strong exploration case without major capital outlay.
Upcoming work continues this capital-efficient methodology. By progressively defining prospects, assessing resource potential, and updating drilling costs prior to full drilling commitment, Prominence aims to conserve capital while retaining substantial exposure to exploration success. The preliminary $5 million drilling cost estimate—covering up to three wells or two wells plus seismic—reflects advantages of targeting shallow, accessible formations in South Australia. This strategy balances risk management with the need to test exploration concepts and advance toward resource discovery.
Existing Cash Reserves Fully Fund 2026 Exploration and Planning
Prominence confirmed that its 2026 exploration program, including drill planning and associated activities, is fully funded by existing cash reserves. This means no additional capital raising or external financing is required to execute the July through December 2026 work schedule. The company’s cash position supports gravity and magnetic data interpretation, prospective resource reviews, drilling engineering studies, and detailed planning without diluting shareholders or incurring debt.
Having internal funding for 2026 work reflects prudent prior capital management and offers operational flexibility as the company moves toward drilling. Maintaining sufficient cash to complete pre-drilling technical work allows Prominence to adhere to its timeline and avoid capital raises that might be negatively viewed by markets. Furthermore, completing technical and resource assessments from internal funds strengthens the company’s standing when engaging potential farm-out or joint venture partners by demonstrating technical commitment and reducing perceived execution risk.
