Platinum Group Metals Ltd. Operational and Strate

VANCOUVER, BRITISH COLUMBIA and JOHANNESBURG, SOUTH AFRICA--(Marketwired - July 31, 2017) - 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, development 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 promptly, 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 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.

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, 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.
