Rock Tech Lithium Inc. represents a significant force in sustainable lithium hydroxide production, essential for electric vehicle batteries. The company integrates mining, refinement, and recycling operations to strengthen the lithium supply chain in North America and Europe. With its primary mining operations in Thunder Bay, Canada, and a converter facility under construction in Guben, Germany, Rock Tech Lithium aims to produce 24,000 tonnes of battery-grade lithium hydroxide annually. The company’s strategy focuses on creating sustainable, localized supply chains while implementing innovative recycling solutions to minimize environmental impact.
Battery Technology
Rock Tech Lithium’s technological approach centers on converting raw lithium materials into high-purity lithium hydroxide suitable for electric vehicle batteries. Their process begins with spodumene extraction from their Georgia Lake project in Ontario, which undergoes sophisticated refinement procedures to meet strict quality standards for battery production.
The company’s Guben converter facility, spanning an area equivalent to 17 soccer fields, implements advanced processing methods to transform raw materials into battery-grade lithium hydroxide. This facility incorporates innovative recycling capabilities, allowing for the reprocessing of used battery materials. Their production system aims for complete material utilization, including the transformation of by-products into valuable materials for other industries, such as cement manufacturing through their partnership with SCHWENK Zement.
Rock Tech’s technological infrastructure supports a closed-loop production model, integrating mining operations with refinement and recycling processes. This integrated approach ensures material conservation while maintaining the high purity levels required for electric vehicle batteries.
Recent Projects
In early 2025, Rock Tech Lithium achieved significant progress at their Guben converter site, including the completion of a railway connection and the successful relocation of the ONTRAS gas pipeline. The company secured $1.4 million CAD from Canada’s Critical Minerals Infrastructure Fund for their Georgia Lake project development. Additionally, they established a partnership with SCHWENK Zement GmbH to convert lithium by-products into cement additives, creating an additional revenue stream while reducing waste.
Investors
Rock Tech Lithium maintains support from various investment sources. CEO and Chairman Dirk Harbecke holds 8.455% of shares, demonstrating significant internal commitment. The investor base includes Laiqon AG (0.3845%), PP-Asset Management GmbH, and HanseMerkur Trust AG. The company has successfully attracted European family offices and investment companies through private placements, while also receiving governmental support for infrastructure development.
