Vancouver, British Columbia and Johannesburg, South Africa--(Newsfile Corp. - May 13, 2021) -  Platinum Group Metals Ltd. (TSX: PTM) (NYSE American: PLG) ("Platinum Group" or the "Company") has received notice that a group from the Kgatlu Community (the "Applicants"), located near planned surface infrastructure associated with the Waterberg Mine, has filed an application for an order in the High Court of South Africa (the "High Court") to review and set aside the decision by the Minister of Environment, Forestry and Fisheries (the "DE") to dismiss an application for condonation for the late filing of an appeal by the Applicants against the Environmental Authorization granted for the Waterberg Mine on November 10, 2020. The Applicants further request that cause be shown as to why the Environmental Authorization granted by the Minister of the DE and the Minister of Mineral Resources and Energy (the "DMR") should not be set aside and referred back to the said ministers for further consideration. The grant of an Environmental Authorization was a prerequisite to the grant of the Waterberg Mining Right by the DMR, which occurred on January 28, 2021. The Company believes that all requirements specified under the National Environmental Management Act, the Mineral and Petroleum Resources Development Act and other applicable legislation has been complied with and that the DE correctly approved and DMR correctly issued the Environmental Authorization. As an interested and affected party, and as a named respondent to the filed court action, Waterberg JV Resources (Pty) Ltd is accordingly opposing the application to the High Court. The Waterberg mining right currently remains active, was notarially executed by the DMR on April 13, 2021 and has been filed for registration.

The Company intends to continue our consultation with the DMR and recognized local authorities and community representatives on our plans for the Waterberg site.
