Rock Tech Lithium and Arcore intend to merge their subsidiaries to create an entirely integrated European lithium supply chain. The NewCo entity will include both Rock Techʼs lithium converter in Guben, Germany, and Arcoreʼs mining project in Lopare, Bosnia-Herzegovina. The merger is intended to create economies of scale, reduce costs, and strengthen competitiveness in the European market.
Rock Tech to control 75 percent of NewCo
Under the signed and thus binding Business Combination Agreement, Rock Tech will hold 75 percent of the shares in NewCo, while Arcore will control 25 percent. The transaction is expected to be completed in the second quarter of 2025. From 2030, the Bosnian project will supply lithium sulphate feedstock, which will be processed into battery grade lithium hydroxide at the Guben converter.
One of the largest European lithium sources
The Guben project has already been approved and is currently in the financing phase. The proposed plant will supply lithium hydroxide for up to 500,000 electric vehicles per year. Arcoreʼs Lopare mining project is currently in the exploration phase. With an estimated 600,000 tons of lithium carbonate equivalent, it could become one of the largest sources of lithium in Europe. A planned feasibility study will clarify the economic and environmental aspects of the project.
