A long-forgotten gas field in eastern Germany has unexpectedly become the focal point of Europe’s commodity market and clean energy sector. Beneath the Altmark plains in Saxony-Anhalt, scientists have confirmed the existence of a vast lithium resource, poised to reshape the region’s battery supply chain over the next decade.
According to data released by Neptune Energy, the lithium reserves discovered in Altmark’s brine deposits are estimated at approximately 43 million tons of lithium carbonate. This figure has been independently verified by Sproule ERCE, adhering to the international CIM/NI 43-101 standards. If commercially developed, Altmark would rank among the world’s largest single-site lithium deposits.
Historically, Altmark has been a hub for natural gas extraction in Germany. During operations, brine—once considered a low-value byproduct—was routinely pumped to the surface from deep reservoirs. Recent analyses, however, reveal unusually high lithium concentrations in this brine, unlocking a transformative opportunity within the existing gas infrastructure.
The project currently encompasses one production license, Jeetze-L, and three exploration licenses: Milde AL, BL, and CL. Leveraging existing infrastructure is a significant advantage, reducing initial investment costs and environmental impact compared to greenfield developments.
A standout feature of the Altmark project is its extraction technology. Instead of conventional open-pit mining or evaporation ponds, Neptune Energy employs Direct Lithium Extraction (DLE). This method isolates lithium directly from deep brine through closed-loop systems, reinjecting the remaining brine back into the reservoir.
Neptune Energy has completed two pilot projects, with the second successfully producing battery-grade lithium carbonate via ion exchange. A third pilot, launching in September 2025, will test adsorption technology. Preliminary assessments indicate DLE uses less land and water, shortens processing times, and aligns with Germany’s stringent environmental regulations.
Geological studies presented at the 2025 EAGE Conference highlight that Altmark’s lithium-rich brine lies between 3,200 and 4,000 meters deep, within sandstone and volcanic rock formations. Average lithium concentrations of 375 mg/liter are deemed ideal for DLE extraction. The region also boasts significant geothermal potential, enabling potential synergies between lithium extraction and thermal energy production.
