ABOUT ROCK TECH LITHIUM 
Rock Tech is enabling the battery age by making the battery industries in Europe and North America more independent and competitive. The Company's goal is to ensure the supply of high-quality, locally produced lithium – supporting a resilient, sustainable, and transparent value chain from mine to battery-grade material.

Rock Tech relies on responsible sourcing, state-of-the-art and proven technologies, and a clear focus on circular economy principles. The Company's lithium hydroxide converter projects in Guben, Germany (24,000 tonnes LHM per year) and Ontario, Canada (up to 36,000 tonnes LCE per year) form the foundation for a stable and regional supply to the battery and automotive industries. The Guben converter has been recognized as a strategic project under the EU Critical Raw Materials Act.

The raw materials for Rock Tech's converter projects are sourced exclusively from verifiably ESG-compliant suppliers. In Canada, Rock Tech relies, among other sources, on its wholly owned Georgia Lake Project, which ensures a stable and sustainable supply for the North American market and is being developed in close partnership with local First Nations communities. By integrating recycled materials, the company aims to close the local battery loop.

With its facilities, Rock Tech makes a central contribution to battery-grade material sovereignty and the achievement of climate targets. The company works in partnership with industry, policymakers, and community groups, and is committed to open communication and the highest environmental standards.
