Vulcan Energy’s first matrix reinjection well delivered an estimated 64 standard litres per second, above the 40-litre assumption underpinning Lionheart’s development plan. The technical progress came alongside €98.0 million of quarterly investing outflows and a cash balance of €129.4 million ahead of expected project debt drawdown in Q1 2027.
- LSC-3a injection capacity estimated at 64 standard litres per second
- €88.8 million spent on Lionheart development during the quarter
- Cash and cash equivalents fell to €129.4 million
- €53.7 million in strategic equity and €10.7 million in grants received
- Project Ludwig PFS reported a €2.6 billion pre-tax NPV8
Lionheart well test exceeds injection assumption
Vulcan Energy Resources Limited (ASX:VUL) has produced one of its clearest pieces of field evidence yet for Project Lionheart, with its first matrix reinjection well recording an estimated injection capacity of about 64 standard litres per second under planned operating conditions. That compares with a development assumption of approximately 40 standard litres per second.
The result came from LSC-3a, a 3,743-metre horizontal sidetrack drilled into a higher-permeability sandstone interval. Vulcan said the test supports the use of lithium-depleted brine to push and actively sweep more of the underground formation, although the company also said the data would be used to investigate further optimisation opportunities. The well was completed during the September quarter and tested after quarter-end.
The result adds technical weight to a project that has moved from financing into heavy construction. Vulcan’s second Lionheart lithium licence was also issued during the quarter, while the Trappelberg well pad neared completion and the company prepared its second drilling rig, V10, for mobilisation in the December quarter.
Construction spending reaches €88.8 million
Lionheart’s progress is consuming cash at a markedly different rate from the company’s earlier development stages. Vulcan spent €88.8 million on property, plant and equipment during the quarter, taking nine-month development expenditure to €256.8 million. The largest quarterly allocations went to the upstream lithium extraction plant at €25.5 million, the Organic Rankine Cycle power plant at €22.7 million and the downstream lithium chemicals plant at €13.0 million.
Construction of the first Interconnected Pipeline and Power section has begun, with completion targeted for the third quarter of 2027. Preparatory work on Section 2 is under way, while tenders for Sections 3 to 7 have been received and contracts are expected to be awarded in the December quarter. Civil works also commenced at the 30MW geothermal plant, and first commercial-scale production of Vulcan’s VULSORB adsorbent began in Germany for the future extraction columns.
Cash falls before project debt drawdown
Cash and cash equivalents fell from €193.9 million at the end of June to €129.4 million at 30 September. Operating activities used €11.1 million and investing activities used €98.0 million, partly offset by €53.7 million in strategic equity proceeds and €10.8 million in German government grants. The company’s project financing facilities remained undrawn, with the first debt drawdown expected in the first quarter of 2027, subject to the relevant conditions.
Vulcan reported €209.4 million of cash and deposits accessible after 90 days, including €80.0 million held in high-interest deposits that were not accessible within 90 days at quarter-end. A further €50.0 million was held as collateral or otherwise restricted under the Lionheart financing arrangements. The Appendix 5B calculation showed 10.1 quarters of funding based on operating and exploration outflows, but that measure excludes the much larger construction and other investing commitments now driving the project’s cash use.
Ludwig offers a second phase, not a second funding call
Beyond Lionheart, Vulcan reported a positive Preliminary Feasibility Study for Project Ludwig, with a pre-tax NPV8 of €2.6 billion and a 25.0% internal rate of return over a planned 30-year operating life. The study also indicated 15% lower capital intensity than Lionheart and increased Ludwig’s indicated lithium resource to 1,251 kilotonnes of lithium carbonate equivalent.
Those figures remain a future option rather than an immediate development commitment. Vulcan said no investment decision will be made on Ludwig until Lionheart is operating successfully, with any future development intended to use asset-level financing alongside strategic partners. For now, the critical test is whether the strong reinjection result can translate into reliable construction, funding execution and commercial production targeted for 2028.
Bottom Line?
The well result reduces one layer of subsurface uncertainty, but Lionheart’s next test is financial: sustaining construction momentum until the expected Q1 2027 debt drawdown without disrupting the project timetable.
Questions in the middle?
- Will the 64-standard-litre-per-second injection result be replicated across Lionheart’s broader well network?
- Will the first project debt drawdown arrive in Q1 2027 on the expected terms and timetable?
- How closely will construction cash use track the funding package as major plant and pipeline work scales up?
