NextSource Closes Overnight Marketed Offering for Gross Proceeds of C$50 Million

/NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES/

TORONTO, Aug. 1, 2023 - (TSX:NEXT) ("NextSource" or the "Company") is pleased to announce that it has closed its previously announced overnight marketed public offering (the "Offering"). Pursuant to the Offering, NextSource issued 30,303,500 common shares of the Company (each a "Share") at a price of C$1.65 per Share (the "Offering Price") for gross proceeds of C$50,000,775. The Offering was conducted through a syndicate of underwriters co-led by Cormark Securities Inc. and BMO Capital Markets, and including Clarus Securities Inc. (collectively, the "Underwriters"), pursuant to an underwriting agreement dated July 13, 2023 entered into among the Company and the Underwriters.

In addition, the Company has granted the Underwriters an option (the "Over-Allotment Option") to purchase up to an additional 15% of the number of Shares issued under the Offering on the same terms exercisable at any time up to 30 days following the date hereof, for market stabilization purposes and to cover over-allotments, if any.

Vision Blue Resources Ltd. ("Vision Blue") purchased 14,151,500 Shares under the Offering to maintain its pro rata ownership in the Company. The Offering is subject to final approval of the Toronto Stock Exchange.

The net proceeds of the Offering are intended to be used by the Company to advance and complete construction of a battery anode facility in Mauritius and other matters as to be described in the Prospectus (as defined below).

The Shares issued under the Offering were qualified for distribution by way of a final short form prospectus dated July 27, 2023 (the "Prospectus") filed in each of the provinces of Canada, other than Quebec, and were offered in the United States on a private placement basis pursuant to an exemption from the registration requirements of the United States Securities Act of 1933, as amended, and applicable state securities laws, and certain other jurisdictions outside of Canada and the United States. A copy of the Prospectus is available under the Company's profile on www.sedarplus.ca.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the Shares in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. This press release does not constitute an offer of Shares for sale in the United States. The Shares offered have not been, nor will they be, registered under the United States Securities Act of 1933, as amended, and such Shares may not be offered or sold within the United States absent registration under U.S. federal and state securities laws or an applicable exemption from such U.S. registration requirements.

The participation of Vision Blue in the Offering constitutes a "related party transaction" pursuant to Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions ("MI 61-101"). The Company has determined that the transaction is exempt from the formal valuation and minority shareholder approval requirements of MI 61-101 by virtue of the exemptions contained in Sections 5.5(a) and 5.7(1)(a) of MI 61-101, as neither the fair market value of securities issued to Vision Blue nor the consideration paid by Vision Blue exceeded 25 percent of the Company's market capitalization. The Company did not file a material change report in respect of the transaction 21 days in advance of closing of the Offering because Vision Blue's participation had not been confirmed. The shorter period was necessary in order to permit the Company to close the Offering in a timeframe consistent with usual market practice for transactions of this nature.
