Platinum Group Metals Ltd.

Operational and Strategic Process Update

VANCOUVER, BRITISH COLUMBIA and JOHANNESBURG, SOUTH AFRICA – 31/07/17 --

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

provides a corporate update regarding the previously announced restructuring of the

Maseve Mine, de velopment work at Waterberg and the ongoing strategic alternatives

process.

Maseve Platinum Mine

The Company has successfully changed the operating plan at Maseve and lowered its

cost structure to align with a reduced production ramp up profile. Production guidance

will be provided as operations commence under the new operating plan in the months

ahead.

Contractor terminations and consultations with labour unions have been completed in a

positive climate of mutual respect and in accordance with the South African Labour Act.

All major contracts and union agreements have been settled and agreed promptl y, in-

line with the Company’s budgeted plan. This has allowed for detailed manpower planning

for the new mine plan going forward.

Details of the new mine plan are in final preparation in consultation with the continuing

mining contractor, Redpath South Africa. Changes to the management and supervision

of the mine have also been made with a focus on near term performance.

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

completed infrastructure and a mill that operates in line with design criteria. During the

transition period, restructuring work has focused on improvements to the underground

infrastructure.

Under the new mine plan, a hybrid method will be utilized, consisting of mechanized

primary access development and conventional stoping. The focus will be to achieve

positive cash flow with tight cost control, as soon as possible. As previously announced

the Company is expected to require US$15 million to US$20 million to achieve this

objective. The company is exploring further debt, the sale of assets or equity as methods

of financing.

Waterberg Project

At the Waterberg Project, the Company has completed a detailed shareholders

agreement with JV partners the Japan Oil, Gas and Metals National Corporation

(“JOGMEC”) and Mnombo Wethu Consultants. The Company is awaiting approval by the

PLATINUM GROUP METALS LTD. …2

Department of Mineral Resources for the transfer of the project Prospecting Permits into

the project holding company, Waterberg JV Resources Pty Ltd. The Company plans for

Waterberg JV Resources Pty Ltd to apply for a mining right in 2017. Funding for the

Waterberg Project is currently provided by JOGMEC as part of their earn-in commitment.

Engineering, drilling, hydrological and geological work for a planned Definitive Feasibility

Study for the Waterberg Project is ongoing.

Strategic Alternatives Update

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

review and assess strategic alternatives. The Company has received several proposals

and is actively engaged in evaluating a number of specific opportunities at both the asset

and corporate levels.

Several expressions of interest have been received for the Maseve Mine assets. The

Company recognizes the opportunity for significant regional synergies in the Western

Bushveld region. In addition to the execution of its own revised mine plan at Maseve,

the Company is actively exploring possible synergies, sale of assets, joint ventures, direct

investment and custom milling.

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.

About Platinum Group Metals Ltd.

Platinum Group, based in Johannesburg, South Africa and Vancouver, Canada, has a

successful track record with more than 20 years of experience in exploration, mine

discovery, mine construction and mining operations.

Formed in 2002, Platinum Group holds significant mineral rights and large-scale reserves

of platinum and palladium in the Bushveld Igneous Complex of South Africa, which is

host to over 70% of the world's primary platinum production. The Company is currently

focused on ramping up the Maseve Mine, its first near -surface platinum mine, to

commercial production.

Platinum Group has delineated new low -cost, near-surface reserves on the North Limb

of the Bushveld Complex on the Waterberg Project. Waterberg represents a new bulk

type of large-scale, shallow low-cost platinum, palladium and gold deposit. Waterberg is

one of the only large-scale dominantly palladium deposits in the world.

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 accordanc e 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, 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; 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. 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.
