HighGold Mining Enters into Agreement for Plan of Arrangement to Spin-out Canadian Properties

Vancouver, March 17, 2023 - HighGold Mining Inc. (TSXV: HIGH) (OTCQX: HGGOF) ("HighGold" or the "Company") is pleased to announce that, further to the Company's news release dated February 22, 2023, HighGold has entered into an arrangement agreement (the "Arrangement Agreement") with Onyx Gold Corp. ("Onyx Gold"), a wholly-owned subsidiary of the Company, pursuant to which the parties intend to complete a spin-out transaction (the "Spin-Out") of the Company's Ontario and Yukon exploration properties (the "Properties") under which the existing shareholders of HighGold will receive one common share in the capital of Onyx Gold ("Onyx Gold Shares") for every four shares held in the capital of HighGold ("HighGold Shares").

The Spin-Out into Onyx Gold will be completed by way of a court approved plan of arrangement under the Business Corporations Act (British Columbia) (the "PoA").

Arrangement Details

Pursuant to the PoA, among other things:

• HighGold will transfer all of the outstanding common shares of Epica Gold Inc. ("Epica"), the wholly-owned subsidiary of HighGold, which owns the Properties, to Onyx Gold;

• In consideration of the foregoing, Onyx Gold will transfer to the Company: (i) the respective number of Onyx Gold Shares equal to the number of HighGold Shares outstanding at the time of the Spin-Out, multiplied by 0.25; and (ii) 5,000,000 Onyx Gold Shares (the "Onyx Gold Spin-Out Shares"). The Company will retain the Onyx Gold Spin-Out Shares as well as the Company's remaining assets and working capital, and continue as a mineral exploration company; and

• Upon closing of the Spin-Out, HighGold shareholders will receive 0.25 of an Onyx Gold Share.

For further details on the PoA, refer to the Arrangement Agreement which will be available on the Company's SEDAR profile.

It is also anticipated that Onyx Gold will complete a concurrent non-brokered private placement of Onyx Gold Shares to fund work programs and for general working capital (the "Concurrent Financing").

The board of directors of the Company has determined that the PoA is in the best interests of the Company. Among other things, the separation of the Properties into a separate public company will position such assets to be valued on a standalone basis. In addition, the transaction will allow the Company's management to focus their efforts on the development of certain other exploration properties with Onyx Gold's management focused on exploring and developing the Properties.

HighGold intends to apply for a listing of the Onyx Gold Shares on the TSX Venture Exchange (the "TSX-V"). Any such listing will be subject to Onyx fulfilling all of the requirements of the TSX-V.

In addition, pursuant to the Arrangement Agreement, the holders of HighGold options and warrants will exchange such securities for new options and warrants of HighGold, respectively, as well as 0.25 of an equivalent security in Onyx Gold. The PoA remains subject to customary conditions, including, among other things, the approval by the TSX-V, approval by an affirmative vote of 66 2/3% of shareholders of the Company in attendance at a meeting of HighGold's shareholders (the "Meeting"), and approval of the Supreme Court of British Columbia. There can be no assurance that such approvals will be obtained or that the PoA will be completed on the terms contemplated, or at all.

Additional details of the PoA will be included in the information circular to be mailed to shareholders of HighGold in connection with the Meeting which will be available on the Company's SEDAR profile. The Company currently anticipates the Meeting to be held at the end of May 2023. The effective date for determining the shareholders of HighGold who are eligible to receive Onyx Gold Shares pursuant to the Spin-Out will be determined and announced in due course.

The securities to be issued under the PoA have not been and will not be registered under the U.S. Securities Act of 1933 and may not be offered or sold in the United States absent registration or applicable exemption from registration requirements. It is anticipated that any securities to be issued under the PoA will be offered and issued in reliance upon the exemption from the registration requirements of the U.S. Securities Act of 1933 provided by Section 3(a)(10) thereof. This press release does not constitute an offer to sell, or the solicitation of an offer to buy, any securities.
