In the news release, "Early Start Permission Received for Rock Tech's first Lithium Converter in

Germany

", issued

12-Jan-2023

by Rock

Tech Lithium Inc. over CNW, the company advises that multiple errors occurred throughout the release.

We are advised by the company that

the second paragraph, third sentence, should read "Rock Tech plans to start initial work on the project, with an estimated cost of

USD 683

million

" rather than "Rock Tech plans to start initial work on the project, with an estimated cost of

650 million euros

,"

and the sixth paragraph,

first sentence should read " To date, more than 250,000 working hours and over

USD 37 million

" rather than " To date, more than 250,000

working hours and over

45 million euros

" as originally issued inadvertently. The complete, corrected release follows:

Early Start Permission Received for Rock Tech's first Lithium Converter in Germany

GUBEN,

Germany

,

Jan. 12, 2023

/CNW/ -

Rock Tech Lithium Inc.

(TSXV: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN: A1XF0V)

(the

"Company" or "Rock Tech") has received permission for an early start to the construction of its lithium converter in Guben,

Germany

(the

"Guben Converter"). The first significant work onsite for this strategic critical mineral project is expected within the upcoming next weeks.

Early Start for Rock Tech's Lithium Converter Approved (CNW Group/Rock Tech Lithium Inc.)

From 2025, the Guben Converter is expected to produce around 24,000 tonnes of battery-grade lithium hydroxide. For this purpose, Rock

Tech recently received approval from the responsible Brandenburg State Office for the Environment for an early start related to the first

tranche of permits. Rock Tech plans to start initial work on the project, with an estimated cost of

USD 683 million

1

, on its own property on

the industrial park in Guben in the upcoming weeks.

Rock Tech applied for the first partial permit and approval for early start in

February 2022

. In the course of the application procedure, which

involved public participation, no objections were received under approval regulations. Rock Tech considers this to be a positive indication of

support for the construction of the Guben Converter and at the same time appreciates the efficient and transparent cooperation with the

authorities.

"Our converter will be one of the first of its kind in

Europe

. The production of our battery-grade lithium hydroxide will be an essential part of

the battery mineral supply chains in

Europe

- this is another reason why the approval by the authority is an important step towards

implementation and sends a clear signal to the market," adds

Klaus Schmitz

, Rock Tech's Chief Operating Officer.

The approval for an early start is also an encouraging indicator that permission for construction of the Guben Converter will be granted in due

course. In November, Rock Tech has submitted the second and final tranche of permit applications for this to the authority. Approval for

construction of the Guben Converter is expected from summer 2023 onwards.

To date, more than 250,000 working hours and over

USD 37 million

2

have been directly invested by Rock Tech in the planning the design and

construction of the Guben Converter. With the early start permission, necessary groundwork as well as the construction of roads, office and

storage buildings can begin.
