Pau, September 3, 2026 - Arverne (FR001400JWR8 - ARVEN),
1. France’s leading provider of geothermal solutions, announces the award of a new exclusive exploration permit for lithium and related substances, known as the “Bassin de Limagne” permit.
Covering an area of 442.68 km² in the Puy-de-Dôme department and granted for a period of five years,this new permit strengthens Arverne’s asset portfolio and confirms its position as the leading French holder of exclusive geothermal exploration permitswith now 9 exclusive exploration permits, including 3 dedicated to lithium.
The award of this permit marks a new step in Arverne’s development in Auvergne, a region where the company has been active for several years.
The perimeter of the “Bassin de Limagne” permit overlaps with that of the “Riom-Clermont-Métropole” permit, also held by Arverne, where 3D exploration has already been carried out to assess the potential of the geothermal heat resource.
Arverne therefore already has advanced knowledge of the subsurface, the geological data and the local area, providing a solid foundation to accelerate the next exploration phases.
In parallel, Arverne and BRGM launched a scientific partnership this year dedicated to the study of the subsurface of the Clermont basin. The teams are collecting, analysing and modelling the available geological, hydrogeological and thermal data. This work builds on research conducted in the region as part of the “The subsurface as a common good” programme in the Massif Central.
This new permit now opens the way to assessing the geothermal lithium potential of the Limagne basin, alongside its geothermal heat potential already studied by Arverne. The ambition is to assess the conditions that could ultimately enable the development of an integrated model combining local production of renewable heat and extraction of geothermal lithiuminspired by the Lithium de France project developed by Arverne in Northern Alsace. The next steps will make it possible to deepen knowledge of the resource and assess its technical, economic and industrial potential.
" We are particularly enthusiastic about opening this new chapter in Auvergne. We have been working on this basin for several years and now have solid knowledge of its geology, its data and its local context.
This new permit allows us to go further: after heat, we will now explore the lithium potential of this subsurface. This is exactly the strategy we want to deploy at Arverne: progressively build a portfolio of high-potential assets and develop the sustainable resources of our subsurface in an integrated way Auvergne could become a major new territory for Arverne tomorrow. This is a new step in the Group’s growth and a further illustration of our ambition to become the French leader in geothermal solutions. ”
