OFFICIAL PERMIT CEREMONY FOR GERMAN LITHIUM REFINERY WITH BRANDENBURG STATE OFFICIALS TODAY. MILESTONE FOR ROCK TECH AND GERMAN BATTERY VALUE-CHAIN

Rock Tech Lithium Inc. has completed the official handover of all construction and operation permit approvals for its German lithium refinery. Today, the State of Brandenburg's Minister for Climate Action and Environment, Axel Vogel, and Minister for Economic Affairs, Joerg Steinbach, handed over the notice of approval for the lithium-hydroxide converter to Rock Tech's chief executive officer, Dirk Harbecke. The handover took place during a meeting in the State Chancellery in Potsdam. Guben's Mayor Fred Mahro and representatives from Rock Tech were also in attendance. All parties welcomed the successful completion of the approval process as a progressive step in the realization of regional and resilient battery supply-chains.

Rock Tech plans to build Europe's first lithium converter with a capacity of 24,000 tonnes of lithium-hydroxide per year. Lithium-hydroxide is required as a raw material for battery production for electric cars and energy storage systems.

Rock Tech's CEO, Mr. Harbecke, states: "I'd like to thank the State of Brandenburg and in particular the State Office for the Environment which was responsible for the permit. The construction and operating licence for our lithium refinery is a strong signal for Rock Tech and Europe. The support of the State, the City of Guben and other stakeholders involved is exceptionally encouraging. The permits not only allow us to now move into the last stage of financing for the project, but they are also proof that our concept works and the Guben converter will serve as the blueprint for our other refinery projects worldwide. We expect to finalize subsidy negotiations and equity term sheets with strategic partners soon. The credit approval process with our banking partners will follow shortly after and we aim to take the final investment decision (FID) in Q3 this year."

Minister Steinbach adds: "I am delighted that the approvals have now been issued and that Rock Tech's construction project is one step closer to realization. The future production of lithium-hydroxide in Guben represents a further building block in the creation of an EV value chain that is currently being established in Brandenburg. The state government is supporting Rock Tech Lithium as much as possible and has initiated all necessary steps."

Additionally, the company announces that it has appointed Derek Sobel to the position of chief financial officer as of June 1, 2024. Mr. Sobel is a chartered professional accountant (CPA, CA) with extensive financial reporting experience in the Canadian public markets. He held the position of head of accounting, audit and tax for Rock Tech since 2021. He follows Sonja Rossteuscher, who has held the position as CFO since November, 2022.

About Rock Tech Lithium Inc.

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, Ont., 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.
