Platinum Group Metals Ltd. Reports Impala’s Waterberg

Amended Purchase and Development Option Agreement

Completed; Work Program in Progress

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

(“Platinum Group” or the “Company”) reports that shareholders of Waterberg JV Resources

Proprietary Limited (“Waterberg JV Co.”) have executed a formal Amended Purchase and

Development Option agreement with Impala Platinum Holdings Ltd. (“Implats”).

In consideration for the amendment, announced February 27, 2020 , Implats is funding

100% of a new implementation budget and work program (the “Work Program ”) effective

February 1, 2020. The Work P rogram, as approved by Waterberg JV Co., is aimed at

increasing confidence in specific areas of the Waterberg DFS while awaiting the expected

grant of a Mining Right and Environmental Authorization and is estimated to cost

approximately Rand 55 million. The Work Program is being carried out remotely and in

compliance with current South African health related stay at home restrictions.

The termination date of Implats’ Purchase and Development Option was amended from the

original date of April 17, 2020 to 90 calendar days following receipt of an executed Mining

Right for the Waterberg Project. All other terms of the Purchase and Development Option

remain unchanged. Amounts spent by Implats for the Work Program will be offset against

Implats’ future development funding commitment should it elect to exercise the Purchase

and Development Option. The previous guidance for the grant of the Mining Right in Q2

2020 may be delayed by the current South African stay at home restrictions.

Platinum Group will continue to be the Manager of the Waterberg Project, as directed by the

technical committee of Waterberg JV Co. A majority of the Company’s South African

personnel are engaged to complete the Work Program , which is being directed by Implats’

technical personnel.

Further detail on the Purchase and Development Option

On November 6, 2017, Implats purchased 15% of the Waterberg JV Co. for US$30 million.

Implats was also granted a Purchase and Development Op tion to increase its stake to

50.01% through additional share purchases from Japan Oil, Gas and Metals National

Corporation (“JOGMEC”) for an amount of US$34.8 million and earn -in arrangements for

US$130 million paid to Waterberg JV Co. to fund development work, as well as a right of

first refusal to smelt and refine Waterberg concentrate.

Estimates of mineralization and other technical information included herein have been prepared

in accordance with NI 43 -101. The definitions of proven and probable reserves used in NI 43 -

101 differ from the definitions in SEC Industry Guide 7. U nder SEC Industry Guide 7 standards,

mineralization may not be classified as a “reserve” unless the mineralization can be economically

and legally extracted or produced at the time the “reserve” determination is made. As a result,

the reserves reported by the Company in accordance with NI 43 -101 may not qualify as

“reserves” under SEC Industry Guide 7. In addition, the terms “mineral resource”, “measured

mineral resource”, “indicated mineral resource” and “inferred 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 historically have not been permitted to be used in reports and

registration statements filed with the SEC pursuant to SEC Industry Guide 7. 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. In particular, “inferred miner al resources” have a great amount of

PLATINUM GROUP METALS LTD. …4

uncertainty as to their existence and great uncertainty as to their economic and legal feasibility.

It cannot be assumed that all or any part of an “inferred mineral resource” will ever be upgraded

to a higher category. Disclosure of “contained ounces” in a resource is permitted disclosure

under NI 43 -101; however, SEC Industry Guide 7 normally only permits issuers to report

mineralization that does not constitute “reserves” by SEC Industry Guide 7 standards as in-place

tonnage and grade without reference to unit measures. 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 requi rements of SEC

Industry Guide 7.
