ROCK TECH LITHIUM ANNOUNCES CLOSING OF OFFERING OF UNITS

Rock Tech Lithium Inc. has closed its previously announced marketed offering of units of the company. In connection with the closing of the offering, the company issued an aggregate of 11,449,743 units at a price of $3.50 per unit for aggregate gross proceeds of approximately $40-million. Each unit comprises one common share in the capital of Rock Tech and one-half of one common share purchase warrant. Each warrant entitles the holder thereof to acquire one common share for a period of 36 months from Aug. 19, 2022, at an exercise price of $4.50, subject to and in accordance with the terms and conditions of the warrant indenture entered into between the company and Computershare Trust Company of Canada, including acceleration and adjustment in certain circumstances. In the event that the volume-weighted average trading price of the common shares on the TSX Venture Exchange for 10 consecutive trading days exceeds $6.75, the company may, within 10 business days of the occurrence of such event, deliver a notice (including a press release) to the holders of warrants accelerating the expiry date of the warrants to the date that is 30 days following the date of such notice.

The underwritten warrants issued pursuant to the offering have been conditionally approved for listing and are expected to commence trading on the TSX Venture Exchange following the closing of the offering, subject to the satisfaction of all listing conditions.

As previously announced, 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, and to finance the continued exploration and development of the company's Georgia Lake lithium project in Ontario, Canada.

The offering included a $30,686,600 underwritten offering conducted through a syndicate of underwriters led by TD Securities Inc. and Cantor Fitzgerald Canada Corp. acting as joint bookrunners and including Berenberg Capital Markets LLC as joint lead manager. The company granted the underwriters an option to purchase up to an additional 15 per cent of the underwritten offering. The overallotment option is 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. The underwriters can elect to exercise the overallotment option for units only, common shares only, warrants only, or any combination thereof, to cover overallotments, if any, and for market stabilization purposes.

In connection with the underwritten offering, the company also completed a non-brokered private placement of 2,682,143 units for aggregate gross proceeds of $9,387,500.50, pursuant to subscription agreements entered into directly between Rock Tech and purchasers. The common shares and warrants issued in connection with the concurrent private placement are subject to a four-month hold period in accordance with applicable Canadian securities laws, which expires four months and one day following the date of issuance thereof, as will any common shares issued on exercise of warrants prior to the expiry of such hold period.

The underwritten offering was made to the public in each of the provinces of Canada, excluding Quebec, pursuant to a prospectus supplement to the company's existing Canadian base shelf prospectus dated July 13, 2022, and in the United States on a private placement basis to qualified institutional buyers pursuant to an exemption from the registration requirements under the U.S. Securities Act of 1933, as amended, and in certain jurisdictions outside of Canada and the United States on a basis that does not require the filing of a prospectus, registration statement or similar document in such jurisdiction.
