Rock Tech Lithium Receives Construction and Operations Permit Approvals for German Lithium Refinery

TORONTO, May 17, 2024 - Rock Tech Lithium Inc. (TSXV: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN: A1XF0V) ("Rock Tech" or the "Company") is very pleased to announce that it has received the full permits for its planned Lithium refinery in Guben, Germany.

Today, the Brandenburg State Office for the Environment issued the final approval for Rock Tech's Lithium refinery. The approval was preceded by an extensive review according to the federal immission control act (BImSchG) by the State Office for the Environment (LfU). The Company plans to produce 24,000 tons of battery-grade lithium hydroxide annually.

"This is an exciting day for Rock Tech. Not only have we received the full permits to operate our Converter in Germany, but also are we the first company in Europe to permit a full-scale Lithium Refinery - without any appeals to the project. This is testament to the great work of our team. I also would like to thank the Brandenburg authorities for their support and diligence." said Rock Tech's Chairman and CEO Dirk Harbecke.

Rock Tech is a cleantech company with operations in Canada and Germany on a mission to produce lithium hydroxide for electric vehicle batteries. The Company plans to build lithium converters at the doorstep of its customers, to guarantee supply-chain transparency and just-in-time delivery, beginning with the Company's proposed lithium hydroxide merchant converter and refinery facility in Guben, Germany. The second Lithium converter is planned to be built in Red Rock, Ontario, Canada. Rock Tech plans to source raw material from its wholly-owned Georgia Lake spodumene project located in the Thunder Bay Mining District of Ontario, Canada, as well as procuring it from other responsibly producing mines. In the years to come, the Company expects to also source raw material from discarded batteries. To close the most pressing gap in the clean mobility story, Rock Tech has gathered one of the strongest teams in the industry. The Company has adopted strict environmental, social and governance standards and is developing a proprietary refining process aimed at further increasing efficiency and sustainability. Rock Tech's goal: to create a closed-loop lithium production system.
