Mining Right Application for Waterberg PGM Project Accepted

(Vancouver/Johannesburg) Platinum Group Metals Ltd. (PTM:TSX; PLG:NYSE American)

(“Platinum Group” “PTM” or the “Company”) is pleased to announce that the recently filed

Mining Right Application (Press Release September 4, 2018) for the large-scale Waterberg

PGM Project has been accepted by South Africa’s Department of Mineral Resources (“DMR”).

The application consists of a Mining Work Program, Social and Labour Plan and associated

Environmental Applications. The application is supported by the Company and all of the

Waterberg JV partners including Impala Platinum Holdings Ltd. (“Implats”), Japan Oil, Gas

and Metals National Corporation (“JOGMEC”) and Mnombo Wethu Consultants (Pty) Ltd.

(“Mnombo”). The process of consultation under the Mineral and Petroleum Resources

Development Act, 2002 ("MPRDA") and the Environmental Assessment regulations, for

consideration of the application has commenced.

Waterberg represents a large-scale resource of platinum group metals (“PGM”), including

palladium, platinum and gold, with an attractive risk profile. Given its shallow nature and

ability to support a fully mechanized operation, the Waterberg Project has the potential to

be amongst the lowest cost producers in the PGM sector. A pre-feasibility study (“PFS”)

was completed in 2016 and a definitive feasibility study (“DFS”) is in progress for completion

in calendar Q1 2019. The DFS is considering two options including the 600,000 tonne per

month mine plan outlined in the PFS and a phased approach commencing with a smaller,

250,000 to 350,000 tonne per month production profile. Stantec Consulting International

LLC and DRA Projects SA (Proprietary) Limited are the lead independent project engineers

for the DFS.

Platinum Group currently holds an effective 50.02% interest in the Waterberg Project.

Implats, the world’s second largest platinum producer, owns a 15% interest. Mnombo, a

black empowerment company, holds a 26% interest. The Company owns a 49.9% interest

in Mnombo. JOGMEC holds a 21.95% interest in the Waterberg Project and is in the process

of transferring a 9.755% interest to Japanese conglomerate Hanwa Co., Ltd. Hosken

Consolidated Investments Limited, a South African black empowerment investment holding

company listed on the JSE with a US$1.1 billion market capitalization, owns a 15% stake in

Platinum Group. Implats is an active participant in the joint venture and holds an option to

increase their stake to 50.01% following the completion of the DFS.

Implats has identified Waterberg as a potential low-cost alternative to deep conventional

PGM mining, with an attractive metal balance for the future. Palladium has been gaining

market interest based on continued strong demand from the auto sector, where there is a

growing trend towards gasoline engines and hybrids that use palladium dominant catalysts.

Estimates of mineralization and other technical information included or referred to herein have

been prepared in accordance with National Instrument 43 -101 – Standards of Disclosure for

Mineral Projects (“NI 43-101”). The definitions of proven and probable Mineral Reserves used

in NI 43-101 differ from the definitions in SEC Industry Guide 7. Under SEC Industry Guide 7

standards, a “final” or “bankable” feasibility study is required to report Mineral Reserves, the

three-year historical average price is used in any Mineral Reserve or cash flow analysis to

designate Mineral Reserves and the primary environmental analysis or report must be filed with

the appropriate governmental authority. As a result, the reserves reported by the Company in

accordance with NI 43 -101 may not qualify as “ Mineral Reserves” under SEC standards. In

addition, the terms “ Mineral Resource” and “measured Mineral Resource” are defined in and

required to be disclosed by NI 43-101; however, these terms are not defined terms under SEC

Industry Guide 7 and normally are not permitted to be used in reports and registration

statements filed with the SEC. Mineral Resources that are not Mineral Reserves do not have

demonstrated economic viability. Investors are cautioned not to assume that any part or all of

the mineral deposits in these categories will ever be converted into reserves. Accordingly,

descriptions of the Company’s mineral deposits in this press release may not be comparable to

similar information made public by U.S. companies subject to the reporting and disclosure

requirements of United States federal securities laws and the rules and regulations thereunder.
