SUPERIOR GOLD FILES MANAGEMENT INFORMATION CIRCULAR IN SUPPORT OF ARRANGEMENT WITH CATALYST METALS

TORONTO, June 5, 2023 /PRNewswire/ - Superior Gold Inc. ("Superior" or the "Company") (TSXV: SGI) (OTCQX: SUPGF) today announced that it has filed a management information circular (the "Circular") for the special meeting of shareholders (the "Meeting") in connection with the proposed arrangement (the "Arrangement") with Catalyst Metals Limited ("Catalyst") (ASX:CYL).

The Circular will be available on Superior's website at https://superior-gold.com and under Superior's SEDAR profile at www.sedar.com and is being mailed, together with the necessary proxy forms, to all Shareholders pursuant to applicable securities laws.

The Superior board of directors (the "Board") encourages Superior shareholders ("Shareholders") to carefully read the information sent to them and to vote their Superior common shares (the "Common Shares") FOR the Arrangement.

Shareholders are urged to vote as soon as possible and well in advance of the proxy submission deadline on June 21, 2023 at 5:00 p.m. (Eastern Time) (or a business day which is at least 48 hours before any adjournment or postponement of the Meeting). For voting assistance, please contact Carson Proxy Advisors at 1-800-530-5189 toll free in North America or 416-751-2066 local (collect outside of North America) or by email at info@carsonproxy.com.

The Circular includes a letter to Shareholders summarizing the reasons why Shareholders should vote FOR the Arrangement. An edited version of the letter to Shareholders follows.

Dear Fellow Shareholders:

You have an important decision to make regarding the proposed business combination of Superior and Catalyst.

The Board believes that the Arrangement will deliver a significant premium and other benefits to Shareholders. The Board unanimously recommends that you vote FOR the Arrangement. The Arrangement can only proceed if, among other conditions, it receives the approval of not less than 66?% of the votes cast by Shareholders in person or by proxy at the Meeting. The Meeting will be held on June 26, 2023 at 10:00 a.m. (Toronto time) at the offices of the Company's external legal counsel, with full details set out in the Circular.

As originally announced on February 23, 2023, Shareholders will receive 0.3571 ordinary shares of Catalyst for each Common Share (the "Consideration") pursuant to the terms and conditions of the arrangement agreement between Catalyst and Superior dated February 22, 2023 (the "Arrangement Agreement"). As of the closing prices on June 2, 2023, that reflects a 59% premium to the Superior Gold share price.

Catalyst controls three significant gold belts in Australia, including the Marymia Gold Project in Western Australia, located adjacent to Superior's Plutonic Gold Operations. With that in mind, the anticipated benefits of the Arrangement for Shareholders include:

• the Consideration for your Common Shares under the Arrangement represents:
• a premium of 62% to the closing price of Common Shares on the TSX Venture Exchange ("TSXV") as of February 22, 2023 and a premium of 52% to the 20-day VWAP of each of Catalyst and Superior on the Australian Securities Exchange (the "ASX") and TSXV, respectively, as of February 22, 2023; and
• more recently, as of June 2, 2023, a premium of approximately 59% to the closing price of Common Shares on the TSXV, based on the closing price of the ordinary shares of Catalyst on the ASX and the prevailing Australian$-Canadian$ exchange rate of 0.889.
• ownership in a well-funded, diversified, ASX-listed producer, with proven operating and exploration capabilities, significantly improving the scale and access to capital as compared to Superior's current status as a single asset producer;
• ongoing exposure to any future value-creating growth projects undertaken by Catalyst at Plutonic Gold Operations, as well as any exploration upside realized across the Plutonic-Marymia gold belt, including:
• exposure to operational synergies with Catalyst's Marymia Gold Project, using Plutonic's excess processing capacity;
• final resolution of the litigation between Superior's wholly-owned subsidiary and a subsidiary of Vango Mining Limited ("Vango"), now owned by Catalyst, which would allow for the exploitation of the prospective Vango mineral property near Plutonic; and
• crystallization of the potential to exploit value in the nearby K2, Trident and Salmon tenements (mining claims) and mines;
• access to a stronger balance sheet and diversified operations; and
• improved trading liquidity and enhanced local attention in Australia, supported by linking the Plutonic mine to an Australian listing, and the potential for analyst and/or business media coverage in Australia.

Following the completion of the Arrangement, Catalyst will maintain its primary listing on the ASX under the symbol "CYL", and Superior will be delisted from the TSXV.

If sufficient Shareholders do not vote for the Arrangement, Superior will continue to trade and conduct its operations as an independent business. Should Superior remain independent, it will face a number of significant risks, including, but not limited to, those risk factors associated with Superior's business described in the Circular, as well as the following risks:

• Superior will have to invest significant capital to access more high-grade stopes at Plutonic. This will take time and will likely require raising capital in the range of US$15 million to US$20 million. If Superior issues equity in exchange for this capital, the dilution to Shareholders could be significant; and
• the litigation between Superior's wholly-owned subsidiary and a subsidiary of Vango will continue (notwithstanding the Supreme Court of Western Australia's ruling in favour of Superior on April 18, 2023), the merit of which litigation remains uncertain and which ruling could eventually be reversed by Australia's High Court.

All the directors and officers of Superior, who together beneficially own or control, directly or indirectly, 1,513,000 Common Shares or approximately 1.2% of the issued and outstanding Common Shares, have agreed to vote their Common Shares for the Arrangement.

In addition, the Arrangement has the support of 4 large institutional Shareholders, who have agreed, subject to the terms of their respective voting and support agreements, to vote approximately 22% of the issued and outstanding Common Shares for the Arrangement. These institutional Shareholders include Franklin Templeton, Aegis Financial Corporation, Donald Smith Value Fund L.P. and one other, each of which has deep expertise in mining investments.

The Arrangement is also supported by a fairness opinion from Superior's financial advisor, National Bank Financial Inc. Analysts with three investment bank that cover Superior have recommended that Shareholders vote for the Arrangement.

As additional support for the Arrangement and as announced by Superior on March 30, 2023, Superior secured a standby loan facility of C$5 million (the "Standby Loan"), as amended, with Auramet International Inc. for working capital purposes in connection with the Arrangement. On May 4, 2023, Superior drew down the full amount of the Standby Loan. The Standby Loan bears interest at a rate of 1% per month and Superior paid an upfront fee in an amount of C$50,000, being 1% of the Standby Loan and a further 2% fee upon drawdown. The maturity date of the Standby Loan was extended and is the earlier of 5 days following completion of the Arrangement or July 7, 2023.

To ensure that your Common Shares are voted at the Meeting in accordance with your instructions, please cast your vote online at www.voteproxyonline.com following the instructions on the enclosed form of proxy.

If you hold Common Shares through a nominee such as a broker, investment dealer, bank, trust company or other intermediary or depositary, you should follow the instructions provided by your nominee to ensure that your vote is counted at the Meeting and you should arrange with your nominee to complete the necessary transmittal documents to ensure that you receive the Consideration for your Common Shares upon completion of the Arrangement.

The Circular dated May 24, 2023 contains a detailed description of the Arrangement and includes certain other information to assist you in considering the matters to be voted upon. You are urged to carefully consider all of the information in the Circular. Please give this material your careful consideration, and if you require assistance, consult your financial, legal, tax or other professional advisors.

Once again, your Board urges you to vote FOR the Arrangement in order to receive the substantial benefits from the Arrangement. Regardless of how many Common Shares you own, your vote is important to reach the required approval threshold of 66?% of the votes cast at the Meeting.

On behalf of the Board, I thank you for your consideration and your support.

Sincerely,
René Marion, Chairman
