Highlights

Vulcan began mobilising its second heavy-duty drill rig to Trappelberg in November 2026.
Its in-house drilling Business Vercana is responsible for the drilling operation.
The company reported an Investment of approximately EUR 51 million in two rigs.
Production and well-count figures remain forward-looking project plans, not completed output.

Vulcan Energy Resources Limited (ASX:VUL) is developing a geothermal lithium and renewable energy business in Germany’s Upper Rhine Valley. On 10 November 2026, the company announced mobilisation of a second heavy-duty drill rig to Trappelberg, the fourth well site within its Lionheart project. The addition expands the equipment available for subsurface development, although mobilisation is not the same as completed drilling or lithium production.

Second Rig Mobilisation at Trappelberg

The newly refurbished V10 rig is being moved into position under the management of Vercana, Vulcan’s in-house drilling company. It is intended to operate alongside existing Lionheart field activity, allowing multiple well sites to be advanced in parallel. Vulcan Energy Resources Limited (ASX:VUL) has described its drilling Assets as a means of controlling schedules and reducing dependence on external contractors.

The company reported investing approximately EUR 51 million, equivalent to about AUD 82 million in its two rigs. That is an equipment investment, not the full Capital cost of the Lionheart development. The company-issued November announcement confirms mobilisation and the equipment strategy; the eventual pace of Well Completion still depends on operational conditions.

Lionheart Combines Lithium and Geothermal Energy

Lionheart is designed around hot underground brines, from which lithium would be extracted before the fluid is reinjected. Vulcan Energy Resources Limited (ASX:VUL) has stated a lithium hydroxide monohydrate production target of approximately 24,000 tonnes annually, supported by planned geothermal power and heat output. Those quantities are project objectives rather than production achieved in 2026.

The broader field plan calls for 28 production and reinjection wells. Earlier reporting indicated seven wells were already in place, but that figure alone does not establish that the entire field is commissioned. Well delivery must ultimately support sufficient brine flow and reservoir performance for the proposed processing facilities.

Investment, Scheduling and Commercial Exposure

In-house drilling capability gives Vulcan Energy Resources Limited (ASX:VUL) greater direct control over staffing, equipment readiness and sequencing. Running multiple rigs may reduce reliance on market availability, but the company remains exposed to geology, drilling performance, permitting and contractor inputs elsewhere in the development.

The company targets the second half of 2028 for initial lithium production. Reaching that milestone requires more than wells: completion of processing infrastructure, successful direct lithium extraction at commercial scale, reliable geothermal operations and appropriate commissioning. The November rig movement does not remove any of those requirements.

Milestones and Technical Risks

Near-term evidence of progress will include completion of mobilisation, drilling at Trappelberg, additional completed wells and updates on wider construction. Vulcan Energy Resources Limited (ASX:VUL) must also demonstrate sustainable operating parameters across the field as planned throughput rises.

Deep geothermal drilling can encounter changing subsurface conditions and technical delays. The large equipment investment creates schedule capability but also represents committed capital. The ultimate Economics depend on project commissioning, lithium sales arrangements and operating performance. Management’s stated timetable should therefore be understood as guidance subject to execution risk, rather than a guaranteed start date.

Key Insights

Vulcan Energy Resources Limited (ASX:VUL) has taken a reported step in Lionheart field execution by mobilising V10. The second rig improves the capacity to pursue parallel well development, but construction, reservoir performance and Downstream processing must still be delivered before planned commercial output.
