Platinum Group Files Final Base Shelf Prospectus

Vancouver, November 13, 2024 - Platinum Group Metals Ltd. (TSX: PTM) (NYSE American: PLG) ("Platinum Group", "PTM" or the "Company") announces that it has filed a final short form base shelf prospectus (the "Shelf Prospectus") with the securities regulatory authorities in each of the provinces and territories of Canada and a corresponding registration statement on Form F-10 (the "Registration Statement") with the United States Securities and Exchange Commission ("SEC") under the Multijurisdictional Disclosure System established between Canada and the United States.

The Shelf Prospectus and the Registration Statement, when made effective, will enable the Company to make offerings of up to US$250 million of common shares, debt securities, warrants, subscription receipts or a combination thereof of the Company from time to time, separately or together, in amounts, at prices and on terms to be determined based on market conditions at the time of the offering and as set out in an accompanying prospectus supplement, during the 25-month period that the Shelf Prospectus and Registration Statement remain effective.

Unless otherwise specified in the prospectus supplement relating to a particular offering of securities, the net proceeds from any sale of any securities will be used to advance our business objectives and for general corporate purposes. The Company filed the Shelf Prospectus and the Registration Statement to replace the Form F-10 registration statement previously filed by the Company with the SEC in 2022, which has expired (the "2022 Registration Statement"), and to enhance the Company's financial flexibility. The Company's 2022 at-the-market common share offering terminated upon the expiration of the 2022 Registration Statement on July 21, 2024. The specific terms of any future offering will be established in a prospectus supplement to the Shelf Prospectus, which supplement will be filed with the applicable Canadian securities regulatory authorities and the SEC.

This news release shall not constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of these securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such jurisdiction. A copy of the Shelf Prospectus can be found on SEDAR+ at www.sedarplus.ca, and copies of the Registration Statement can be found on EDGAR at www.sec.gov. Copies of the Shelf Prospectus and the Registration Statement may also be obtained by contacting the Corporate Secretary of the Company at Suite 838, 1100 Melville Street, Vancouver, British Columbia, Canada, V6E 4A6.
