Platinum Group Metals Reports on Maseve Mine Operations

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

(“Platinum Group” or the “Company”) reports that during March 2017 the Maseve Mine

produced approximately 2,477 ounces of platinum, palladium, rhodium and gold (“4E”)

in concentrate. Production in March 2017 was the best level achieved since completion

of commissioning in 2016 and shows a positive trend. Production ramp-up is following a

positive trend but is behind schedule. Further improvement in the ramp -up rate is

required. The results for March demonstrate improved stoping and tramming as well as

the positive effects of Block 11 production coming online. Planned conveyor and silo

completions are on track targeted to be completed at the end of April and are expected

to facilitate and continue to improve performance.

Mining and Milling Overview

Improvements in stoping tonnes versus development during production ramp -up from

Block 11 are in progress at the time of writing. Production levels in January and into

February 2017 were hampered by the process of changing the prima ry underground

mining contractor, senior management changes, equipment operator performance and

slowly improving equipment availability. Production during February, 2017 was also

hampered by an extraordinary rain event over a period of days around February 20,

2017, which caused regional surface flooding and some underground flooding at the

Maseve Mine, resulting in several lost mining and milling days. Production in March was

improved, but was below target and did not offset the lower January and February

results.

A summary of monthly production for the second fiscal quarter plus the month of March,

2017 follows:

Month Dry Tonnes

Milled

Average

Grade

gms/tonne

Recovery % 4E Ounces in

Concentrate

December, 2016 39,297 1.51 79.2 1,509

January, 2017 34,661 1.53 79.2 1,351

February, 2017 29,146 1.59 80.3 1,193

March, 2017(1) 51,663 1.81 82.6 2,477

(1) Approximately 7,825 dry tonnes of ore mined in February, 2017 were milled in March, 2017.

Several important operational advancements were completed during the last few

months:

• Significant advancement into Block 11 in preparation for increased mining from this

important mining block was achieved. Double decline roadway access to Block 11

was competed at the end of December 2016. Five development ends and 17 mining

faces or “bords” are now active in Block 11, representing an increase of nine mining

faces since December, 2016. The work focus in Block 11 has changed from

predominantly development to mechanized bord and pillar mining.

• Redpath Mining South Africa is currently continuing with the construction of a 1.0 km

conveyor at their cost. During January, 2017 Redpath entered a letter of intent

whereby they would install, operate and maintain a 1.0 km conveyor towards Block

11, linking into underground si los and the existing 1.4 km conveyor to surface and

1.7 km conveyor system into the mill. Approximately 30% of this conveyor steel work

is installed and the construction is on track for completion at the end of April. Cost for

the conveyor installation to be borne by Redpath was estimated at Rand 25.0 million

(approximately US$1.8 million), which Redpath plans to recoup by way of a per tonne

charge.

• During the second fiscal quarter ended February 28, 2017 , approximately a 20%

monthly cost reduction has been completed through a process of rationalizing and

consolidating underperforming and redundant contractors. This process was

undertaken cooperatively with the involvement of affected contractors, the Nati onal

Union of Mineworkers, and on occasion, the Department of Minerals Resources. Many

mining services previously provided by several contractors are now consolidated

under the management of Redpath. As the changeover process is completed, the

Company expects to achieve improved production and cost efficiencies because of

these changes.

Block 11

The contribution of mined tonnage from Block 11 is a critical factor to achieving positive

cash flow at the Maseve Mine. Block 11 is a large, well -drilled and stable mining block

estimated to host 545,000 4E Merensky Reef ounces (3,066,512 tonnes at 5.53 gpt 4E

Indicated). This block is modelled as flat dipping at an average of nine degrees, with an

average seam thickness of 157 cm (as published in the technical report titled “An

Independent Technical Report on the Maseve Project (WBJV Project areas 1 and 1A)

located on the Western Limb of the Bushveld Igneous Complex, South Africa” dated

August 28, 2015, with an effective date of July 15, 2015). The flat dip and good quality

of Block 11 reef has been confirmed with over 100 meters of strike length exposed in

underground development.

During 2017, Block 11 is scheduled to build up to 70 -80% of mined ore flow. At full

production Block 11 is planned to provide up t o 76,000 tonnes a month of mined ore

flow. Historical monthly mined tonnes for Block 11 are recorded in the table below:

Month Block 11 Mined

Percentage

December, 2016 8,388 27,559 30.4%

January, 2017 16,614 28,733 57.8%

February, 2017 20,759 43,742 47.5%

March, 2017 29,690 49,610 59.8%

The rate of underground development and the increase of stoped tonnes versus

development at the Maseve Mine continues to be an important factor with respect to

mine ramp-up and production rates.

Labour

Mill operating contractor, Tailing Technology (“TT”), has reported to the Company that

the Association of Mineworkers and Construction Union (“AMCU”) was recently recognized

by them with approximately a 58% membership (approximately 62 people). AMCU has

provided a set of demands and TT is in negotiations with AMCU. TT and AMCU met with

the South African Commission for Conciliation, Mediation and Arbi tration on March 31,

2017 for mediation, u nfortunately no agreement was reached , and a s a result t he

commission is reported to have issued a strike certificate on April 3, 2017. If AMCU

wishes to take strike action, they must provide 48 hours written notice. TT advises the

Company that they are striving to find a solution and that they remain confident they will

be able to run the Maseve mill and limit any potential disruptions if AMCU chooses to go

on strike.

Outlook

Delays in underground development, stoping rates and planned tonnages have resulted

in ounce production delays. Such delays have had, and will continue to have, a negative

impact on working capital requirements until sufficient mined stoped material is produced

to allow mine operations to generate positive cash flow.

As a result of the production performance for the first calendar quarter , estimated

calendar 2017 annual production guidance, based on the current mine plan, is adjusted

from 100,000 ounces 4E to 85,000 ounces 4E.

The Company plans to report on the operational and financial details of its second fiscal

quarter ended February 28, 2017 on or before April 14, 2017.

The Company is currently working with BMO Ca pital 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" feasi bility 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

report must be filed with the appropriate governmental authori ty. 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 resource s 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 securiti es 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 permitted

disclosure under Canadian securities laws; ho wever, 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. Accordingly,

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.
