Platinum Group Metals Ltd.

Waterberg Project Joint Venture Advances

VANCOUVER, BRITISH COLUMBIA and JOHANNESBURG, SOUTH AFRICA – 4/08/17 --

Platinum Group Metals Ltd. (TSX:PTM) (NYSE:PLG) (“Platinum Group” or the “Company”)

announces that the transfer of all Waterberg Prospecting Rights held by the Company to

a dedicated j oint venture corporation, Waterberg JV Resources (Pty) Ltd, has been

approved by the South African Department of Mineral Resources (“DMR”). Platinum

Group Metals RSA Pty Ltd (100% owned by the Company) owns a 45.65% direct interest

in the Waterberg Projec t. The Japan Oil, Gas and Metals National Corporation

(“JOGMEC”) holds a 28.35% direct interest in the project and BEE partner Mnombo Wethu

Consultants (Pty) Ltd (“Mnombo”) holds a direct 26.0% interest. The Company currently

holds a 49.0% interest in Mnombo.

The Waterberg Project is one of the few large palladium dominant deposits in the world.

The Company believes that as a result of its shallow depth, good grades and a fully

mechanized mining approach, the Waterberg Project has the opportunity to be a safe

mine within the lowest quartile of the industry cost curve. The project resources consist

of 60% palladium and the Independent Pre-Feasibility Study on the Waterberg Project

estimates that Waterberg will produce 472,000 ounces of palladium annually … about

6% of the world's palladium production in 2015. Producing approximately 744,000 4E

ounces per year, Waterberg would be one of the largest platinum group metals mine

complexes in South Africa . Please refer to the Independent Technical Report on the

Waterberg Project Including Mineral Resource Update and Pre -Feasibility Study dated

October 17, 2016 and filed at www.sedar.com for additional information.

JOGMEC has now completed their USD $20 million funding commitment to the project

and their interest can be vested in the joint venture company.

R. Michael Jones CEO of Platinum Group Metals Ltd said “We are very pleased that the

DMR has approved the transfer of the ownership structure to our dedicated joint venture

company at this time. The transfer allows us to prepare to file a mining right application

and work on specific financing alternatives and strategic transactions. Interest in the

Northern Limb and palladium have increased recently.”

The Company has active interest in its Waterberg Project from multiple parties in South

Africa and internationally, with discussions ongoing. Interest in Waterberg is driven by

the strategic nature of the Waterberg deposit as one of the only significant primary

platinum and palladium assets globally with a thick, low cost, fully mechanized mine

plan. The deposit is in contrast to narrow, high cost, deep level platinum mining. The

Company regards Waterberg as an important core asset with industry strategic value.

Cautionary Note to U.S. and other Investors

Estimates of mineralization and other technical information included or referenced in this

press release 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. Under SEC Industr y Guide 7 standards, a "final" or "bankable" feasibility study is

required to report reserves, the three-year historical average price is used in any reserve

or cash-flow analysis to designate reserves and the primary environmental analysis or

the 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

"reserves" under SEC standards. In addition, the terms "mineral resource", "measured

mineral resourc e", "indicated mineral resource" and "inferred mineral resource" are

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

PLATINUM GROUP METALS LTD. …4

defined terms under SEC Industry Guide 7 and normally are not permitted to be used in

reports and regist ration 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; "inferred mineral resources" have a great amount of 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. Under Canadian securities laws, estimates of inferred

mineral resources may not form the basis of feasibility or pre -feasibility studies, except

in rare cases. Additionally, disclosure of "contained ounces" in a resource is p ermitted

disclosure under Canadian securities laws; however, the SEC normally only permits

issuers to report mineralization that does not constitute "reserves" by SEC standards as

in place tonnage and grade without reference to unit measurements. According ly,

information contained or referenced in this press release containing descriptions of the

Company's mineral deposits 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.
