- Vulcan Energy boosts lithium resources at Mannheim, Germany
- 3.22 million tonnes of lithium carbonate equivalent now estimated
- Geothermal potential adds clean energy prospects
Vulcan Energy (ASX:VUL) has announced a substantial increase in its lithium resource estimate at the Mannheim prospect, located within Germany’s Upper Rhine Valley Brine Field (URVBF). The updated estimation now stands at 3.22 million tonnes of lithium carbonate equivalent (LCE), with an average lithium grade of 155 mg/L. This marks a significant rise of 1.39 million tonnes LCE compared to the company’s earlier assessment.
The update is based on an extensive 3D seismic survey and resource modelling, which includes both indicated and inferred resources. This strategic development underlines Vulcan Energy’s ambition to become a leading integrated provider of lithium and renewable geothermal energy across Europe.
In addition to the lithium resources, the company has reported a maiden geothermal resource. The new geothermal estimates include an indicated resource of 2,848 petajoules (PJ), with 171 PJ considered recoverable, and an inferred resource of 10,539 PJ, with 3,777 PJ recoverable. This dual resource — both lithium and geothermal — positions Vulcan Energy strongly within the clean-tech ecosystem.
The Mannheim prospect forms a crucial part of Vulcan’s broader “Lionheart” Phase One development plan. A Scoping Study is being planned to advance the asset further, including delivering sustainable baseload geothermal heat to MVV Energie’s (ETR:MVV1) district heating network in Germany. This integration of clean lithium production and renewable energy supply is aligned with Europe’s broader push for energy independence and climate neutrality.
The URVBF — where Mannheim is situated — is not only the largest lithium resource in Europe but is also known for its high-grade brine geothermal characteristics. These factors significantly enhance the economic and strategic value of Vulcan’s assets. The company plans to replicate the current development model in future phases across the region bordering Germany and France.
As a constituent of the ASX 200, Vulcan Energy’s progress at Mannheim could attract growing attention from environmentally-conscious investors and stakeholders focused on energy transition and critical raw materials supply chains.
By expanding its lithium and geothermal resources, Vulcan Energy (VUL) is reinforcing its long-term vision of sustainable lithium extraction and clean energy integration — a model that aligns with the global shift toward green technology and climate resilience.
