Disclosure

Technical and Scientific Information This presentation has been prepared by Platinum Group Metals Ltd. (“Platinum Group”

• r

the “Company”). Information included in this presentation regarding the Company’s mineral properties has been compiled by R. Michael Jones, P.Eng, the President and Chief Executive Officer of the Company, and a non-independent Qualified Person for purposes

• f

National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”), based

• n

independent information filed by the Company with the Canadian securities regulators and the U.S. Securities and Exchange Commission (“SEC”). R. Michael Jones, the QP who has compiled the technical info for the presentation, has approved the written disclosure regarding technical and scientific information in this presentation. For more detailed information regarding the Company and its mineral properties, you should refer to the Company’s independent technical reports and other filings with the Canadian securities regulators and the SEC, which are available at www.sedar.com and www.sec.gov, respectively. Scientific and technical information contained herein is derived from the Company’s technical reports. Information contained herein related to the Waterberg Definitive Feasibility Study and associated Reserve and Resource Update can be found in the October 4, 2019 technical report entitled, “Waterberg Project Definitive Feasibility Study and Mineral Resource Update.” www.sedar.com and www.sec.gov.. Reference is made to such reports for more detailed information with respect to the Company’s properties, including details of quality and grade

• f

each mineral resource estimate, details of the key assumptions, methods and parameters used in the mineral resource estimates and a general discussion of the extent to which the mineral resource estimates and the

• ther estimates and projections included in the

reports may be materially affected by any known environmental, permitting, legal, taxation, socio- political, marketing, or other relevant issues. Cautionary Note to United States Investors Estimates of mineralization and other technical information included

• r

referenced in this presentation 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

• f

"contained

• unces" 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 presentation 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.

Forward Looking Statements

This presentation contains forward-looking information within the meaning of Canadian securities laws and forward-looking statements within the meaning of U.S. securities laws (collectively “forward-looking statements”). Forward-looking statements are typically identified by words such as: believe, expect, anticipate, intend, estimate, plans, postulate and similar expressions, or are those, which, by their nature, refer to future events. All statements that are not statements

• f

historical fact are forward-looking statements. Forward-looking statements in this press release include, without limitation, statements regarding the projections and assumptions relating to the DFS, including, without limitation NPV, IRR, costs, mine life, payback periods, margins, exchange rates, inflation, recoveries, grades, potential production

• f

the Waterberg Project and other operational and economic projections with respect to the Waterberg Project; Waterberg Project’s potential to be a bulk mineable, low cost, dominantly palladium mine producing platinum and palladium based on a fully mechanized mine plan; the Waterberg Project’s potential to be one of the largest and lowest cash cost underground platinum group metals mines globally; the projected receipt of the Mining Right in Q1 2020, first production in late 2023 and steady state production by 2027; the expected creation of 1,100 new highly skilled jobs; the potential for future drilling to convert mineral resources into reserves, extending mine life; and the potential for underground mining of the North Mine to lower future capital costs. Mineral resource and reserve estimates are also forward-looking statements because such estimates involve estimates of mineralization that may be encountered in the future if a production decision is made, as well as estimates of future costs and values. Although the Company believes the forward-looking statements in this press release are reasonable, it can give no assurance that the expectations and assumptions in such statements will prove to be

• correct. The Company cautions investors that any

forward-looking statements by the Company are not guarantees of future results or performance and that actual results may differ materially from those in forward-looking statements as a result

• f

various factors, including the Company’s inability to generate sufficient cash flow or raise sufficient additional capital to make payment on its indebtedness, and to comply with the terms
