TECHNICAL AND SCIENTIFIC INFORMATION

This presentation has been prepared by Platinum Group Metals Ltd. (“Platinum Group” or 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 of National Instrument 43-101 - Standards of Disclosure

for Mineral Projects (“NI 43-101”), based on independent technical reports, and other information filed by the Company with the Canadian securities regulators and the U.S. Securities and Exchange

Commission (“SEC”).

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. Technical information

related to the Maseve Mine (WBJV Project 1 Platinum Mine) can be found in the August 28, 2015 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 and filed on www.sedar.com and www.sec.gov. Scientific or technical information contained herein related to the Waterberg

Project can be found in the October 19, 2016 technical report titled “Independent Technical Report on the Waterberg Project Including Mineral Resource Update and Pre-Feasibility Study” and filed on

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 of each mineral reserve and

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

reserve and mineral resource estimates and the other 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

As a Canadian issuer that is eligible to use the U.S./Canada Multijurisdictional Disclosure System (MJDS), the Company is permitted to prepare its public disclosures and this presentation in accordance with

Canadian securities laws, which differ in certain respects from U.S. securities laws. In particular, this presentation uses the terms “mineral resource”, “measured mineral resource”, “indicated mineral resource”

and “inferred mineral resource”. While these terms are recognized and required by Canadian securities laws, they are not recognized by the SEC. In addition, “reserves” reported by the Company under

Canadian standards may not qualify as reserves under SEC standards. U.S. investors are cautioned not to assume that any part of a “mineral resource”, “measured mineral resource”, “indicated mineral

resource” or an “inferred mineral resource” will ever be converted into a “reserve.” Under U.S. standards, mineralization may not be classified as a “reserve” unless the mineralization can be economically and

legally extracted or produced at the time the “reserve” determination is made. “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. Historical results or feasibility models presented herein are not

guarantees or expectations of future performance.

Information included in this presentation, the Company’s independent technical reports and the Company’s other public statements related to its mineral properties has been prepared in accordance with

securities laws in effect in Canada, which differ from U.S. securities laws. The SEC permits U.S. mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can

economically and legally extract or produce. The Company uses certain terms in this presentation, such as “resources,” that the SEC’s guidelines strictly prohibit U.S. public companies from including in their

filings with the SEC. Accordingly, information contained or referenced in this presentation containing descriptions of the Company’s mineral deposits may not be compatible to similar information made public by

U.S. companies subject to the reporting and disclosure requirements of U.S. federal securities laws, rules and regulations.

This presentation also contains information about adjacent properties on which the Company has no right to explore or mine. The Company advises you that the SEC’s mining guidelines strictly prohibit

information of this type in documents filed with the SEC. Investors are cautioned that mineral deposits on adjacent properties are not indicative of mineral deposits on the Company’s properties.

This presentation is not an offer to sell, or a solicitation to buy, any securities in any jurisdiction. The Toronto Stock Exchange and the NYSE MKT LLC have not reviewed and do not accept responsibility for the

accuracy or adequacy of this presentation, which has been prepared by the Company.

Forward Looking Statements

Certain of the statements made herein, including statements regarding the Company’s business plans and objectives; production estimates and assumptions, including production rate, grade per tonne and

smelter recovery; production timing; revenue, cash flow and cost estimates and assumptions; statements with respect to future events or future performance; anticipated exploration, development, construction,

production, permitting and other activities on the Company’s properties; ; the adequacy of capital, financing needs and the availability of and potential for receiving further commitments; project economics;

future metal prices and exchange rates; mineral reserve and mineral resource estimates; and potential changes in the ownership structures of the Company’s projects constitute “forward-looking statements”

and “forward-looking information” within the meaning of applicable U.S. and Canadian securities legislation (collectively, “forward-looking statements”).

Forward-looking statements reflect the current expectations or beliefs of the Company based on information currently available to the Company. Forward-looking statements in respect of capital costs,

operating costs, production rate, grade per tonne and concentrator and smelter recovery are based upon the estimates in the technical reports referred to herein and in the documents referred to herein and

ongoing cost estimation work, and the Forward-looking Statements in respect of metal prices and exchange rates are based upon the three year trailing average prices and the assumptions contained in such

technical reports and ongoing estimates. Forward-looking statements are subject to a number of risks and uncertainties that may cause the actual events or results to differ materially from those discussed in

the forward-looking statements, and even if events or results discussed in the forward-looking statements are realized or substantially realized, there can be no assurance that they will have the expected

consequences to, or effects on, the Company. Factors that could cause actual results or events to differ materially from current expectations include, among other things: uncertainty of production, development

plans and cost estimates for the Maseve Mine (WBJV Project 1 and Project 3); additional financing requirements to achieve the Company’s business objectives and remain in compliance with the covenants set

forth in its debt financing facilities; the Company’s history of losses; the inability of the Company to generate sufficient cash flow to make payment on its indebtedness under its debt financing facilities and

comply with the restrictions imposed by such indebtedness; the debt financing facilities are secured and the Company has pledged its shares of its South African subsidiary to the lenders which potentially could

result in the loss of the Company’s interest in the Maseve Mine, the Waterberg Project and in the South African subsidiary in the event of a default under either facility; the Company’s negative cash flow; the

Company’s ability to continue as a going concern; delays in the production ramp-up of the Maseve Mine which could result in a default under its debt financing facilities; delays in, or inability to achieve, planned

commercial production; completion of a feasibility study for the Waterberg Project, which is subject to resource upgrade and economic analysis requirements; discrepancies between actual and estimated

mineral reserves and mineral resources, between actual and estimated development and operating costs, between actual and estimated metallurgical recoveries and between actual and estimated production;

fluctuations in the relative values of the U.S Dollar, the Rand and the Canadian dollar; volatility in metal prices; the failure of the Company or its joint venture partners to fund their pro-rata share of funding

obligations for Project 1 or the Waterberg Project; the inability of the Company to find an additional and suitable joint venture partner for Project 1 and Project 3 within such timeframe as may be determined by

the South African Department of Mineral Resources; any disputes or disagreements with the Company’s joint venture partners; the ability of the Company to retain its key management employees and skilled

and experienced personnel; contractor performance and delivery of services, changes in contractors or their scope of work or any disputes with contractors; conflicts of interest; litigation or other legal or

administrative proceedings brought against the Company; actual or alleged breaches of governance processes or instances of fraud, bribery or corruption; exploration, development and mining risks and the

inherently dangerous nature of the mining industry, including environmental hazards, industrial accidents, unusual or unexpected formations, safety stoppages (whether voluntary or regulatory), pressures, mine

collapses, cave-ins or flooding and the risk of inadequate insurance or inability to obtain insurance to cover these risks and other risks and uncertainties; property and mineral title risks including defective title to

mineral claims or property; changes in national and local government legislation, taxation, controls, regulations and political or economic developments in Canada, South Africa or other countries in which the

Company does or may in the future carry out business; equipment shortages and the ability of the Company to acquire the necessary access rights and infrastructure for its mineral properties; environmental

regulations and the ability to obtain and maintain necessary permits, including environmental authorizations and water use licences; extreme competition in the mineral exploration industry; delays in obtaining,

or a failure to obtain, permits necessary for current or future operations or failures to comply with the terms of such permits; risks of doing business in South Africa, including but not limited to labor, economic

and political instability and potential changes to and failures to comply with legislation; and the other risks disclosed in the Company’s Annual Information Form for the year ended August 31, 2016, which is

available on SEDAR at www.sedar.com and is included as part of the Company’s Form 40-F annual report filed with the SEC at www.sec.gov. You are advised to review these risk factors, and not to place

undue reliance on forward-looking statements.

The Company undertakes no obligation to update publicly or release any revisions to forward-looking statements to reflect events or circumstances after the date of this presentation or to reflect the occurrence

of unanticipated events except as required by law.

Redpath Mining South Africa (Pty) Ltd. (subsidiary of Canadian-headquartered Redpath Mining

Contractors and Engineers) awarded tender to develop and mine Block 11 and appointed

principal mining contractor at Maseve.

Redpath has been mining long hole sections in Blocks 9 and 12 to date.

Current investment by Redpath of 25M ZAR ($1.8M approx.) to construct the 1.0 km conveyor

linking Block 11 to underground silos, surface conveyor and milling facility.

Redpath will earn back its investment based on a charge per tonne of ore conveyed – has added

four trucking units on a rental basis in the interim.

Synergistic investment represents confidence in the potential at Maseve as production ramps up

in 2017.

Waterberg Project

Thick - amenable to bulk mechanized mining – higher

skilled and educated work force.

Shallow - deposit starts 140m from surface.

Near surface T Reef and Super F allowing for potential

multi decline ramp access for equipment - lower capital

costs compared to vertical shafts.

Size allows for consideration of large scale operations

and downstream options.

Desirable low chrome concentrate with base metal

content amenable to existing smelters.

Thickness makes the difference – in ounces, mining

methods and costs.

A typical mining block in the Merensky Reef is 1m

thick and 250m X 250m contains 30,000 ounces

On the Super T Zone, an actual 250m X 250m Block

in the PFS is 11m thick at 5.02 g/t and contains

estimated 258,000 ounces 4E, Indicated

On the Super F Zone an actual 250m x 250m Block in

the PFS is 25.2m thick at 4.12 g/t 4E and contains an

estimated Indicated 613,725 ounces 4E, Indicated

(Blocks from Resource Model – Independent Technical Report On

the Waterberg Project, Oct 19, 2016, www.sedar.com)

T Zone Block Model Example


▪ Existing known deposit extends for

13km and is open along strike

going North and at depth.

▪ Current drilling targeting open, up

dip “Super F” zones and thickening

“T” Zone in the south.

▪ Focus on areas 30m+ in thickness

at depths less than 200m from

surface.

▪ Thick, shallow “Super F” zones will

have important mine plan

implications.

▪ Feasibility Study drilling has begun.

▪ Potential for “Super T” zones in the

southern portion of the ore body.

1. Mineral Resources and Mineral Reserves are classified in accordance with the SAMREC standards. There are certain differences with the “CIM Standards on Mineral Resources and Reserves”; however, in this case the Company believes the differences are not material

and the standards may be considered the same.

2. Mineral Reserves are a subset of the Mineral Resources and are provided on a 100% project basis.

3. Mineral Reserves are supported by a mine plan that uses conventional, hybrid and bord and pillar mining with varying costs and thickness.

4. A planning cut-off grade of 2.5 g/t for both the Merensky and UG2 Reefs were calculated to delineate the mining blocks from the resource model. The Mineral Resources and Mineral Reserves have payable credits in copper, nickel, ruthenium and iridium.

5. Cut off for the Merensky and UG2 reefs were estimated using average costs, smelter discounts, concentrator recoveries and mine call factor.

6. Mineral Resources were completed by Charles Muller of CJM Consulting, and the Mineral Reserves were prepared under the supervision of Gert Roets of DRA.

7. Mineral Resources were calculated using Kriging methods for geological domains created in Datamine from 6413 borehole assay results and geological information from underground workings. The Mineral Reserves were assessed using a Datamine block model and

Datamine Mine Design software (Studio-5D Planner) for the mine design and Datamine EPS (Enhanced Production Scheduler) software for the Life of Mine schedule. Economic models completed by the Company were reviewed for cut-off assessment.

8. The calculation of Mineral Resources and Reserves has taken into account environmental, permitting, legal, title, taxation, socio-economic, marketing and political factors. The Mineral Resources and Mineral Reserves may be materially affected by metals prices,

exchange rates, labour costs, electricity supply issues or many other factors detailed in the Company’s Annual Information Form.

9. The following prices based on a 3 year trailing average in accordance with U.S. Securities and Exchange Commission (“SEC”) guidance was used for the assessment of Resources and Reserves; USD Pt 1,408/oz, Pd 744/oz, Au 1,374/oz, Rh 1,126/oz, Ru 73/oz, Ir 731/oz, Cu

Reasonable prospects of economic extraction were determined with the following assumptions: Metal prices used in the reserve estimate are as follows based on a 3-year trailing average (as at July 31/2016) in accordance with U.S. Securities and Exchange Commission ("SEC") guidance for the assessment of resources and reserves; US$1,212/oz Pt, US$710/oz Pd, US$1229/oz Au, US$984/oz Rh, US$6.10/lb Ni, US$2.56/lb Cu, US$/ZAR15. Smelter payability of 85% was estimated for 4E and 73% for Cu and 68% for Ni. The effective date is October 17, 2016. A 2.5 g/t Cut-off was used and checked against a pay-limit calculation. Independent Qualified Person for the Statement of Reserves is Mr. RL Goosen (WorleyParsons RSA (Pty) Ltd Trading as Advisian). The mineral reserves may be materially affected by changes in metals prices, exchange rates, labor costs, electricity supply issues or many other factors. See Risk Factors in 43-101 report on www.sedar.comand the Company’s Annual Information Form. The reserves are estimated under SAMREC with no material difference to the CIM 2014 definitions in this case. The estimation of mineral reserves has taken into account environmental, permitting and legal, title, taxation, socio-economic, marketing and political factors. Based on the cut-off grade and a maximum depth cut-off of 1,250 meters the Probable reserve will support an 18 year mine life.

4E = Platinum Group Elements (Pt+Pd+Rh+Au). The cut-offs for mineral resources have been established by a qualified person after a review of potential operating costs and other factors. The mineralresources stated above are shown on a 100% basis, that is, for the Waterberg Project as a whole entity. Conversion Factor used – kg to oz = 32.15076. Numbers may not add due to rounding. Resources donot have demonstrated economic viability. A 5% and 7% geological loss has been applied to the Indicated and Inferred categories respectively. Effective Date Oct 17, 2016. Metal prices used in the reserveestimate are as follows based on a 3-year trailing average (as at July 31/2016) in accordance with U.S. Securities and Exchange Commission ("SEC") guidance for the assessment of resources; US$1,212/ozPt, US$710/oz Pd, US$1229/oz Au, US$984/oz Rh, US$6.10/lb Ni, US$2.56/lb Cu, US$/ZAR15.

Total aggregate mineral resources at Waterberg on a 100% project basis have increased slightly since those reported in April 2016. Inferred category resources have decreased to an estimated 10.8 million4E ounces from 11.71 million ounces 4E Inferred in April, 2016. Indicated category resources have increased to an estimated 24.9 million 4E ounces, from 23.9 million 4E ounces Indicated in April 2016:

1. The mineral resources are classified in accordance with the SAMREC standards. There are certain differences with the "CIM Standards on Mineral Resources and Reserves"; however, in this case theQP believes the differences are not material and the standards may be considered the same. Mineral resources that are not mineral reserves do not have demonstrated economic viability and Inferredresources have a high degree of uncertainty.

2. The mineral resources are provided on a 100% project basis and Inferred and Indicated categories are separate and the estimates have an effective date of 17 October 2016.

3. A cut-off grade of 2.5 g/t 4E for both the T and the F-Zones is applied to the selected base case mineral resources.

4. Cut off for the T and the F-Zones considered costs, smelter discounts, concentrator recoveries from previous engineering work completed on the property by the Company. The resource model wascut-off at an arbitrary depth of 1,250 meters, although intercepts of the deposit do occur below this depth.

5. Mineral resources were completed by Mr. CJ Muller of CJM Consulting.

6. Mineral resources were estimated using kriging methods for geological domains created in Datamine from 303 original holes and 483 deflections. A process of geological modelling and creation ofgrade shells using indicating kriging was completed in the estimation process.

7. The estimation of mineral resources has taken into account environmental, permitting and legal, title, and taxation, socio-economic, marketing and political factors.

8. The mineral resources may be materially affected by metals prices, exchange rates, labor costs, electricity supply issues or many other factors detailed in the Company's Annual Information Form.

9. The data that formed the basis of the estimate are the drill holes drilled by Platinum Group, which consist of geological logs, the drill hole collars surveys, the downhole surveys and the assay data.The area where each layer was present was delineated after examination of the intersections in the various drill holes.

10. There is no guarantee that all or any part of the mineral resource not included in the current reserves will be upgraded and converted to a mineral reserve.
