Rock Tech Lithium Inc. Announces Proposed Public Offering of Units

VANCOUVER, Aug. 08, 2022 - Rock Tech Lithium Inc. (TSX-V: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN: A1XF0V) (the "Company" or "Rock Tech") is pleased to announce that it intends to undertake an underwritten marketed offering (the "Offering") of units of Rock Tech ("Units") for gross proceeds of approximately US$50 million, subject to market conditions and other factors. Each Unit will be comprised of one common share in the capital of Rock Tech (a "Common Share") and one half Common Share purchase warrant (each whole Common Share purchase warrant, a "Warrant"). Each Warrant will entitle the holder thereof to acquire one Common Share (a "Warrant Share") for a period of 18 months from the date of issuance of such Warrant, subject to and in accordance with the terms and conditions of the warrant indenture to be entered into between the Company and Computershare Trust Company of Canada.

The Offering will be conducted through a syndicate of underwriters (the "Underwriters") led by TD Securities Inc. and Cantor Fitzgerald Canada Corporation acting as joint book-runners and including Berenberg Capital Markets, LLC as joint lead manager. The Company expects to grant the Underwriters an option (the "Over-Allotment Option") to purchase up to an additional 15% of the Offering. It is anticipated that such Over-Allotment Option will be exercisable, in whole or in part at the discretion of the Underwriters, at any time up to and including 30 days following the closing date of the Offering.


OFFERING DETAILS

The number and pricing of Units offered pursuant to the Offering and the exercise price of the Warrants will be determined in the course of marketing and in the context of market conditions and other factors, with the final terms of the Offering to be determined at the time the Company enters into a definitive underwriting agreement with the Underwriters. Closing of the Offering will be subject to a number of customary closing conditions, including acceptance of the TSX Venture Exchange (the "TSX-V"). There can be no assurance as to whether or when the Offering will be completed, or as to size or terms of the Offering.

Rock Tech currently intends to use the net proceeds of the Offering to finance the development of the Company's proposed high grade lithium hydroxide converter and refinery facility in Guben, Germany (the "Guben Converter"), to fund the continued exploration and development of the Company's Georgia Lake lithium project in Ontario, Canada (the "Georgia Lake Project") and for general corporate purposes.

The Offering will be made to the public in each of the provinces of Canada, excluding Québec, pursuant to a prospectus supplement (the "Prospectus Supplement") to the Company's existing Canadian base shelf prospectus dated July 13, 2022 (the "Base Shelf Prospectus") and in the United States on a private placement basis to "qualified institutional buyers" pursuant to an exemption from the registration requirements under the United States Securities Act of 1933, as amended (the "U.S. Securities Act"). In addition, the Underwriters (directly or through affiliates or selling group members) may offer Units pursuant to the Offering in such jurisdictions outside of Canada and the United States as agreed between the Company and the Underwriters on a basis which does not require the filing of a prospectus, registration statement or similar document in such jurisdiction.

The Prospectus Supplement and the Base Shelf Prospectus contain important information about the Company and the Offering. Prospective investors should read the Prospectus Supplement and the Base Shelf Prospectus, including the documents incorporated by reference therein, before making an investment decision. Copies of the preliminary Prospectus Supplement, the Base Shelf Prospectus and all documents incorporated by reference therein are available electronically on Rock Tech's SEDAR profile at www.sedar.com.
