ROCK TECH LITHIUM APPOINTS ESTHER BAHNE AS DIRECTOR

Rock Tech Lithium Inc. has appointed Esther Bahne to its board of directors.

Ms. Bahne was appointed as the company's chief marketing and strategy officer in October, 2021. She took on the role to reposition Rock Tech as a cleantech company and define the brand around ambitious sustainability goals. During this time, Rock Tech has closed a large equity financing backing its plans to build Europe's largest lithium hydroxide plant and build up a strong team of employees and partners.

"We have achieved major milestones in record time," said Ms. Bahne. "Rock Tech Lithium is helping to future-proof our industry while spearheading low-carbon, closed-loop industrial production. We are striking out on a new path, and I am proud to help our strong team stay the course."

"Esther brought on a strong strategic vision and is an expert in communication," said Dirk Harbecke, Rock Tech's chairman. "Add to that her intimate knowledge of the automotive industry, and it is clear why we are pleased to see her join the team for the long term."

Ms. Bahne has more than 16 years of experience in the car industry. Reporting directly to the board of BMW Group, she served as the global head of strategy and CMO at MINI after taking on the relaunch of the MINI brand in 2015. At Audi AG, where she started her career as spokeswoman of the board, she set up the corporate sustainability strategy and ran the social innovation practice. Ms. Bahne also founded the influential start-up accelerator Urban-X, built a design centre in New York and steered the world's largest co-living company as co-chief executive officer.

Ms. Bahne will resign her position as chief marketing and strategy officer of Rock Tech with immediate effect to concentrate on her duties as a member of the company's board of directors. Ms. Bahne will join the board, effective March 11, 2022.

About Rock Tech Lithium Inc.

Rock Tech is a cleantech company with operations in Canada and Germany that aims to supply the automotive industry with high-quality lithium hydroxide made in Germany. As early as 2024, the company intends to commission Europe's first lithium converter with a nameplate production capacity of 24,000 tonnes per year. This is equivalent to the volume needed to equip around 500,000 electric cars with lithium-ion batteries.

The company has set itself the goal of creating the world's first closed loop for lithium, thus closing the raw material gap on the road to clean mobility. Rock Tech owns the Georgia Lake project in Ontario, Canada, and, as early as 2030, around 50 per cent of the raw materials used are expected to come from the recycling of batteries.
