Restructures Maseve Platinum Mine

VANCOUVER, BRITISH COLUMBIA and JOHANNESBURG, SOUTH AFRICA – 07/07/17 --

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

is taking steps to restructure its mining operations at the Maseve Mine in South Africa.

The restructuring would involve a change in primary mining method and cost reductions

to create a sustainable future for the mine. The changes are operationally driven to align

costs with a more gradual ramp-up of production using more selective mining methods.

The Maseve Mine has good potential in terms of grades, underground developed access,

completed infrastructure and a mill that operates in accordance with design criteria.

As a result of the anticipated restructuring process, there are a large number of

employees in the service of independent contractors and staff of Masev e who could be

affected. Platinum Group Metals will work closely with all its contractors , including

Redpath Mining South Africa, the largest mining contractor on site, to minimize job losses

while making the operation self-sustainable. It is likely that Redpath will continue to be

the main contractor at the mine.

Contractors will be paid in the normal course, and the Company will honor obligations to

its employees. The Company will work with all its contractors and staff under Section 189

and 189A of the Labour Relations Act in South Africa. Severance, job planning and other

support will be provided . Platinum Group will also work closely with organized labor

during this process.

New opportunities for contractors and employees will be created as the new ly planned

mining method ramps up. In the long term , the hybrid method is more labor intensive

offset with better planned grade compared to bord-and-pillar mining.

“We see good potential for a sustainable mine at Maseve. The South African government

and the local community have been very supportive of the Maseve Mine, and we deeply

value their assistance and support,” said R. Michael Jones, CEO, Platinum Group . “We

will work with our contractors, employees and other stakeholders in a climate of mutual

respect, as we transition through the proposed restructuring process.”

The restructuring aims to reduce ongoing costs and achieve positive, sustainable cash

flows as soon as possible, utilizing already-established infrastructure. A "hybrid" mining

method is under consideration, which would result in a transition from the current higher

volume, mechanized bord-and-pillar mining method. Hybrid mining involves mechanized

access drives using the mine’s current equipment as well as conventional manual

methods for stoping . Both bord -and-pillar and hybrid methods were included in the

mine’s feasibility study.

Face grades at the Maseve mine have generally met estimates, but the fully mechanized

mining method has resulted in excess dilution and therefore lower grades to the plant.

The Maseve concentrator plant has performed in excess of design criteria. Completed

underground conveyor infrastructure will help reduce the trucking fleet required for

mining from Block 11, the target for immediate mining.

The Company has notified the Department of Mineral Resources that a restructuring is

required to create a viable operation and to ensure optimal mining of the resource, and

that it will comply with the applicable provisions of Section 52 of the Mineral and

Petroleum Resources Development Act (MPRDA).

As the Company develops and implements the new hybrid mining ramp -up plan, it will

assess its new production guidance. Previous guidance will change. In coming months,

Platinum Group will provide operational updates on the results of the hybrid mining ramp-

up.

The Company has received waivers from its lenders related to working capital and

production covenants to October 31, 2017. The Company will assess the new plan’s

ability to meet the lending covenants and loan requirements in the months ahead. The

Company may require further financing in debt, equity or from asset sales.

The Company continues to work with BMO Capital Markets and Macquarie Capital to

review and assess corporate and asset level strategic alternatives.

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 Industry 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 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 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; "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, estimate s 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 permitted

disclosure under Canadian securities laws; however, the SEC no rmally 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. Accordingly,

information contained or referenced in this press release containin g 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.
