Lithium de France has secured a EUR 40 million capital increase, further supporting the pre-industrial phase of its geothermal lithium project in Alsace.
The Arverne Group has announced that its subsidiary, Lithium de France, has completed a Series B2 financing round thus increasing its capital by EUR 40 million. The financing comes as the geothermal lithium project of Lithium de France enters the pre-industrial phase, including the start of drilling operations, the direct lithium extraction (DLE) demonstrator, and the detailed preliminary design.
The capital increase was subscribed by Arverne and Equinor Ventures, both previous investors in Lithium de France. Following this transaction, Arverne Group will now hold 64.58% of the capital and Equinor Ventures will hole 24.40%.
A few months ago, Arverne announced the start of construction of the DLE demonstrator in the Bas-Rhin region of Alsace, France. The demonstrator aims to validate the lithium extraction process from geothermal brines in the Rhine Basin, optimizing yield, selectivity, and environmental impact.
“This capital financing transaction is a key step in the Lithium de France project, whose mission is to accelerate the energy transition to serve regional prosperity,” said Pierre Brossollet, Founder and CEO of Arverne.
“Lithium is one of the critical metals essential to meet the expected growth of electric vehicles and battery energy storage. I welcome the renewed support of Equinor, whose geological knowledge and experience in project execution will be decisive assets.”
“Equinor is pleased to continue its strategic partnership with Lithium de France and reiterates its confidence in the company by continuing to invest through its venture capital arm. We look forward to working with Lithium de France to develop a new supply chain by deploying DLE technology,” added Lisa Rebora, Equinor’s Global Head of Lithium.
