Germany Just Discovered a $1.27 Trillion Lithium Deposit… Or Did It?

Germany has made global headlines with reports of a 43 million tonne lithium deposit beneath the Altmark gas field in the North German Basin. At current lithium carbonate prices, the in-place value has been estimated at over 1.27 trillion AUD. But what does the geology actually say? This deep dive explores the Permian Rotliegend sandstones, lithium-rich brines at depths of 3–4 kilometres, water–rock interaction processes, recovery factors, and whether this is truly one of the world’s largest lithium deposits or simply a theoretical resource. Learn how ancient desert basins, volcanic mica breakdown, and sedimentary basin evolution created a potential lithium brine system that could influence Europe’s energy transition and battery supply chain.
