VANCOUVER, British Columbia, Jan. 20, 2023 (GLOBE NEWSWIRE) -- Regulus Resources Inc. ("Regulus" or the "Company", TSX-V: REG, OTCQX: RGLSF) is pleased to announce that its non-brokered private placement (the "Private Placement"), previously announced on December 22, 2022, has been upsized to 22,658,974 common shares ("Common Shares") at a price of C$1.02 per Common Share for total gross proceeds of C$23,112,153.

On December 22, 2022 the Company announced a strategic investment by Nuton, a Rio Tinto Venture, ("Nuton") to acquire an approximate 16.5% interest in Regulus. The Company's largest shareholder, Route One Investment Company LLC ("Route One"), has elected to participate in the Private Placement by agreeing to purchase 2,600,000 Common Shares at a price of C$1.02 per share.

Upon closing the financing, Route One will own 21.81% and Nuton will own 16.11% of the Company. The Company plans to use the proceeds to advance the AntaKori project and for general corporate purposes.

Closing of the financing is expected by the end of January and is subject to various conditions including approval of the TSX venture Exchange. No finders fee is payable in connection with the Private Placement.

Route One is a control person of the Company. Accordingly, the participation of Route One in the Private Placement constitutes a related party transaction under Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions ("61-101"). The Company is exempt from formal valuation and minority approval under MI 61-101 as the fair market value of Route One's participation in the Private Placement does not exceed more than 25% of the market capitalization of the Company, as set forth in Sections 5.5(a) and 5.7(1)(a) of MI 61-101.

The Company will not file a material change report more than twenty-one (21) days before the expected closing date of the Private Placement as the details of the Private Placement were not finalized until January 19, 2023, and the Company wishes to close the Private Placement as soon as practicable.

The securities referred to in this news release have not been, nor will they be, registered under the United States Securities Act of 1933, as amended, and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons absent U.S. registration or an applicable exemption from the U.S. registration requirements.
