NEWS RELEASE

Great Panther Mining Receives Delisting Notice from the Toronto Stock Exchange

This news release constitutes a "designated news release" for the purposes of the Company's prospectus supplement dated October 15, 2021, to its short form base shelf prospectus dated September 10, 2021.

Vancouver, BC, September 27, 2022 – Great Panther Mining Limited (TSX:GPR; OTCPK:GPLDK) (“Great Panther” or the “Company”), announces that following a delisting review by the Toronto Stock Exchange ("TSX"), the Company's common shares (the “Shares”) will be delisted from the TSX effective close of market on October 27, 2022.

Trading of the Shares on the TSX has been suspended since September 6, 2022, as a result of the Company filing a notice of intention to make a proposal under the Bankruptcy and Insolvency Act (Canada) (the "BIA"). This suspension will continue until the delisting takes effect. As previously announced, the Shares were delisted from the NYSE American LLC ("NYSE American") on September 14, 2022.

The Shares are currently quoted on the OTC Pink operated by the OTC Markets Group Inc. (the "OTC Pink"). The Company expects that the OTC Pink will provide significantly less liquidity than the TSX and NYSE American, and can provide no assurances regarding trading volumes, trading prices or that the Shares will continue to be quoted on the OTC Pink. Due to the risks and uncertainties resulting from the BIA proceedings, trading in the Shares during the pendency of the BIA proceedings poses substantial risks.

Shareholders retain their legal rights and equity interest and are advised to contact their brokerage where shares are held regarding retention policies for unlisted shareholdings and potential for shares to trade in over-the-counter markets.
