Lithium de France reports exceptional success for their first drilled geothermal well in Alsace, with well parameters exceeding all initial objectives.
Following the start of well testing reported about a month ago, Lithium de France has now announced the success of the company’s first geothermal well drilled at the Schwabwiller site in Alsace, France. The well parameters have exceeded all initial objectives, as detailed below:
- Temperature of 145 °C
- Flowrate of 275 cubic meters per hour
- Lithium content of 180 ppm
- Productivity of 10 L/s/bar
Moreover, no induced seismicity was detected during the drilling and well testing operations. As the company statement indicates, the results of the first well confirm the existence of an exceptional geothermal resource and validate the industrial potential of the site.
Drilling at the Schwabwiller site started in November 2025, targeting a depth of about 2400 meters. The drilling operations are expected to be completed by mid-2026. The operations are being carried within the boundaries of two license areas granted to Lithium de France. The goal for the project is to supply geothermal heat to businesses, farms, and local communities in northern Alsace, while providing a source from which lithium will be extracted.
