Vancouver, British Columbia and Johannesburg, South Africa–(Newsfile Corp. – August 2, 2021) – Platinum Group Metals Ltd. (TSX: PTM) (NYSE American: PLG) ("Platinum Group" or the "Company") reports the receipt of notice that the Mining and Environmental Justice Community Network of South Africa, claiming to be a community networking body, together with a group of residents from certain communities located near planned surface infrastructure associated with the Waterberg Mine (the "Applicants"), intend to apply for an order (the "Application for Motion") in the High Court of South Africa (the "High Court") restraining Waterberg JV Resources (Pty) Limited ("Waterberg JV Co.") from carrying on mining related activities on portions of the farms Goedetrouw and Ketting pending the finalization of the Appeals and the Review (as defined below) and the grant of various regulatory authorizations.

A mining right for the Waterberg Project was granted by the South African Department of Mineral Resources and Energy ("DMRE") on January 28, 2021 and was notarially executed on April 13, 2021 (the "Waterberg Mining Right"). After the grant of the mining right the Company received notice of and reported several appeals by objecting groups to the decision by the DMRE granting the Waterberg Mining Right (the "Appeals"). The Company also received notice of an application for an order in the High Court to review and set aside the decision by the Minister of Environment, Forestry and Fisheries to dismiss an application for condonation for the late filing of an appeal against the environmental authorization granted for the Waterberg Mine on November 10, 2020 (the "Review").

The Company believes that all requirements specified under the MPRDA have been complied with and that the DMRE correctly granted the mining right and environmental authorization. Counsel acting for Waterberg JV Co. has filed formal rebuttals to each Appeal reported above, is opposing the Review, and will file answering papers to the Application for Motion. The Waterberg Mining Right currently remains in good standing.

The Company's near-term objectives are to continue working closely with established local community leadership to maximize the value of the Waterberg Project for all stakeholders and to complete construction funding and concentrate offtake arrangements for the Waterberg Project.
