Platinum Group Metals Ltd. Reports 2021 Annual Results

(Vancouver/Johannesburg) Platinum Group Metals Ltd. (PTM:TSX; PLG:NYSE American)

(“Platinum Group”, “PTM” or the “Company”) reports the Company’s financial results for

the year ended August 31, 2021 and provides an update and outlook. The Company is

focussed on advancing the palladium dominant Waterberg Project located on the North ern

Limb of the Bushveld Complex in South Africa (the “Waterberg Project”). The Waterberg

Project is planned as a fully mechanised , shallow, decline access palladium, platinum, gold

and rhodium (“4E”) mine and is projected to be one of the largest and lowest cost

underground platinum group metals (“PGM” or “PGMs”) mines globally.

The Company’s near-term objectives are to advance the Waterberg Project to a development

and construction decision and complete construction funding and concentrate offtake

arrangements. The Company is also advancing an initiative through Lion Battery Technologies

Inc. (“Lion”) using platinum and palladium in lithium battery technology in collaboration with

Anglo American Platinum Limited (“Anglo”) and Florida International University (“FIU”). Lion

is focussed on securing further patents for technologies developed through its ongoing

research and development.

The Company has filed a Form 20 -F annual report (“Form 20-F”), including the Company’s

audited consolidated financial statements (the “Financial Statements”), for the year ended

August 31, 2021 with the U.S. Securities and Exchange Commission (the “SEC”) on EDGAR

(www.sec.gov) and an Annual Information Form (“ AIF”) and Management’s Discussion and

Analysis with Canadian securities regulators on SEDAR (www.sedar.com). The Form 20-F and

AIF are also available on the Company’s website at www.platinumgroupmetals.net.

Shareholders may receive a hard copy of the complete Financial Statements from the

Company free of charge upon request.

All amounts herein are reported in United States dollars unless otherwise specified. The

Company holds cash in Canadian dollars, United States dollars and South African Rand .

Changes in exchange rates may create variances in the cash holdings or results reported.

Recent Events

On October 14, 2021, the Company reported completion of a geotechnical drilling campaign

at the Waterberg Project. The campaign consisted of 46 boreholes drilled along the planned

centerline of two sets of twin declines and box-cut positions. A total of 5,966 metres of drill

core were recovered and a total of 2,696 metres of core were geotechnically logged from

within the zone of interest. Downhole geophysical surveys were conducted. Core samples of

all the major geotechnical units en countered were collected and subjected to laboratory

testing. Geotechnical qualified persons monitoring the drill programme have stated that in

general, the rock mass encountered along both decline routes is competent and can support

the planned excavations with no major problem areas expected.

PLATINUM GROUP METALS LTD. …2

On July 6, 2021 , Waterberg JV Resources Proprietary Limited (“ Waterberg JV Co. ”)

completed the registration of the Waterberg Mining Right at the Minerals and Petroleum Titles

Registration Office. The Waterberg Mining Right was notarially executed by the Department

of Mineral Resources and Energy (“DMRE”) on April 13, 2021 and remains active.

On June 15, 2021, the U.S. Patent and Trademark Office issued Patent No. US 11,038,160

B2 entitled “Battery Cathodes for Improved Stability” to FIU. The patent covers a preparation

method using PGM catalysts in carbon materials for use as cathodes with increased emphasis

on Lithium Sulphur Batteries. The patent broadens protection for Patent No. US 10,734,636

B2 issued to FIU on August 4, 2020, covering the composition of carbon cathodes containing

PGMs. Under a sponsored research agreement, the Company’s subsidiary Lion has exclusive

rights to such battery technology being developed by FIU, including patents granted. Lion

was jointly formed in 2019 by Platinum Group and Anglo to accelerate the development of

next-generation battery technology using platinum and palladium.

On and following March 5, 2021, three notices of appeal were filed by individual appellants

against the January 28, 2021 granting of the Waterberg Mining Right. Counsel acting for one

group filed an application for an order in the High Court of South Africa to review and set

aside the decision by the Minister of the Department of Forestry, Fisheries, and the

Environment to refuse condonation for the late filing of that group’s appeal against the grant

of an Environmental Authorization for the Waterberg Mine in November 2020. Waterberg JV

Co. has filed formal rebuttals to each action. On July 30, 2021, a group located near planned

surface infrastructure filed an urgent interdict appl ication. Waterberg JV Co. promptly filed

an answering affidavit denying urgency and arguing that the application is without merit. The

applicants did not respond and were obliged to remove their application from the urgent court

roll. Host community Ketting has applied to join as an interested party to the application and

another host community submitted a confirmatory affidavit, both communities being in

support of the Waterberg Mine. A time frame for a hearing of the interdict application is

uncertain or may never occur.

On February 5, 2021, the Company entered into an Equity Distribution Agreement with BMO

Capital Markets Corp. (“BMO”) to sell its common shares from time to time for up to $ 50.0

million in aggregate sales proceeds in “at -the-market” transactions (the “2021 ATM”). At

August 31, 2021, the Company had sold 2,502,790 common shares at an average price of

$4.3754 pursuant to the 2021 ATM for net proceeds of $10.7 million after fees and expenses

of $954 thousand, including brokerage fees of $274 thousand. As of November 24, 2021, the

Company has issued a total of 4,433,448 common shares at an average price of US $2.63,

pursuant to the 2021 ATM for net proceeds of $11.4 million. No offers or sales of common

shares were made in Canada, to anyone known to be a resident of Canada or on or through

the facilities of the Toronto Stock Exchange (the “TSX”) or other trading markets in Canada.

On January 28, 2021, the DMRE granted Waterberg JV Co. the Waterberg Mining Right.

On December 8, 2020, the Company closed a non-brokered private placement of 1,121,076

common shares at a price of $2.23 per share to existing major beneficial shareholder, Hosken

PLATINUM GROUP METALS LTD. …3

Consolidated Investments Limite d (“ HCI”) through its subsidiary Deepkloof Limited

(“Deepkloof”), resulting in gross proceeds to the Company of $2.5 million and allowing HCI

to maintain approximately a 31% interest in the Company as they held prior to the at -the-

market offering completed by the Company on November 30, 2020 (the “2020 ATM”), as

described below.

On November 30, 2020 , the Company completed the 2020 ATM , first announced on

September 4, 2020 , pursuant to an Equity Distribution Agreement with BMO whereby

Platinum Group sold 5,440,186 common shares in the capital of the Company at an average

price of $2.21 for gross proceeds of $12.0 million. No offers or sales of common shares were

made in Canada, to anyone known to be a resident of Canada or on or through the facilities

of the TSX or other trading markets in Canada.

Results For The Year Ended August 31, 2021

During fiscal 2021, the Company continued its efforts to lower costs. During the year ended

August 31, 2021, the Company incurred a net loss of $13.1 million (August 31, 2020 – net

loss of $7.1 million). The loss in the previous comparable year was lower due to a $3.1 million

realized gain on the expiry of warrants in the previous comparable year. Share based

compensation was $3.2 million (August 31, 2020 $1.6 million) with the increase due to a

higher fair value for options granted during the current ye ar resulting from a higher share

price at the grant date. General and administrative expenses during the year were $ 5.1

million (August 31, 2020 - $3.7 million) with the increase due mostly to a $0.828 million

severance payment to the Company’s former CEO pursuant to a formal separation agreement.

Interest expense of $ 5.1 million (August 31, 2020 - $5.5 million) was lower due to the

reduction in debt during the current year. The currency translation adjustment recognized in

the year is a gain of $4. 9 million (August 31, 2020 - $4.5 million loss) due to the Rand

increasing in value relative to the U.S. Dollar during the current year.

At August 31, 2021, finance income consisting of interest earned and property rental fees in

the year amounted to $0.1 million (August 31, 2020 - $0.2 million). Loss per share for the

year amounted to $0.18 as compared to a loss of $0.11 per share for fiscal 2020.

Accounts receivable at August 31, 2021 totalled $0.3 million (August 31, 2020 - $0.2 million)

while accounts payable and other liabilities amounted to $2.5 million (August 31, 2020 - $1.4

million). Accounts receivables were comprised mainly of value added taxes repayable to the

Company in South Africa. Accounts payable consisted primarily of payables related to

geotechnical drilling on the Waterberg Project.

Total expenditures on the Waterberg Project, before partner reimbursements, for the year

were approximately $3.7 million (August 31, 2020 - $3.0 million). At year end, $44.0 million

in accumulated net costs had been capitalized to the Waterberg Project (August 31, 2020 -

$34.9 million). Total expenditures on the property since inception to August 31, 2021 are

approximately $77.5 million.

Outlook

The Company’s primary business objective is to advance the Waterberg Project to a

development and construction decision. The Company and Waterberg JV Co. are in process

to design, budget and carry out pre-construction work programmes for the Waterberg Project,

including the er ection of fences, ground clearing, geotechnical drilling and infrastructure

engineering and surveying. The Company continues to work closely with regional and local

communities and their leadership on how the mine can be developed to provide optimal

outcomes and best value to all stakeholders. The Company continues to work on advancing

project permitting, infrastructure servitudes and community relationships with its partners

Impala Platinum Holdings Ltd. (“Implats”), Mnombo Wethu Consultants (Pty) Ltd.

(“Mnombo”), Japan Oil, Gas and Metals National Corporation (“JOGMEC”) and Hanwa Co.

Ltd. (“Hanwa”) through a technical committee of Waterberg JV Co.

The Member of the Executive Committee (“ MEC”) for the Limpopo Department of Economic

Development, Environment and Tourism, Mr. Thabo Andrew Mokone, recently undertook to

investigate the appeals and court actions described above. During September 2021, the MEC

held regular engagements with representatives of Waterberg JV Co. and the commun ity

leaders of Kgatlu village. In late October 2021, a mediation process commenced between the

parties with the objective of resolving matters of concern.

The Company and Waterberg JV Co. have begun a process to assess commercial alternatives

for mine development, financing and concentrate offtake. Several parties are currently in

discussions with the Company. Implats ’ offtake right of first refusal allows Implats the

opportunity to match any offtake terms offered by a bona fide third party. Discussions with

Implats on concentrate offtake also continue. Further, the Company is conducting research

and formal studies to assess the economic feasibility of establishing a dedicated Waterberg

matte furnace as an alternative to a traditional concentrate offtake arrangement.

The market for PG Ms, palladium and rhodium in particular, has generally improved since

2019. In 2021, the impact of a global shortage of semi-conductor chips did result in reduced

global automotive production, resulting in a concurrent reduction in demand for PGMs. Prices

for each of the PGMs have fallen from their zeniths in approximately February to April of 2021.

Auto market recovery to pre-COVID production levels is forecast by some market analysts in

2023/2024.

The Company’s battery technology initiative through Lion with Anglo represents a new

opportunity in the high-profile lithium battery research and innovation field. The investment

in Lion creates a potential vertical integration with a broader industrial market development

strategy to bring new technologies to market which use palladium and platinum. Research

and development efforts by FIU on behalf of Lio n continue. Technical results from Lion’s

research may have application to most lithium-ion battery chemistries and the scope of Lion’s

research work is being expanded.
