released.

On February 11, 2022 , the Company completed a non -brokered private placement of

3,539,823 Common Shares at a price of $1.695 per Common Share to existing major

beneficial shareholder, Hosken Consolidated Investments Limited (“ HCI”), resulting in

proceeds to the Company of $6.0 million (the “Private Placement”). Pricing of the Private

Placement was consistent with the equity consideration paid by the Company to purchase and

cancel its outstanding $19.99 million 6 7/8% Convertible Senior Subordinated Notes

(“Convertible Notes”) as described below. The Private Placement allowed HCI to return to

a near 26% interest in the Company, as it held prior to the purchase and cancellation of the

Convertible Notes.

On February 11, 2022 , the Company reported the privately negotiated purchase and

cancellation of the Company’s Convertible Notes maturing on July 1, 2022. The Company

issued to the holders, on a private placement basis, an aggregate of 11,793,509 Common

Shares of the Company at a price of $1.695 per share in consideration for the $19.99 million

principal outstanding balance of the Convertible Notes. The Company paid accrued and

unpaid interest on the Convertible Notes in cash.

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 encountered were collected and subjected to laboratory

testing. Geotechnical qualified persons monitoring the drill program have sta ted 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.

Results For The Year Ended August 31, 2022

During fiscal 2022, the Company continued its efforts to lower costs. During the year ended

August 31, 2022, the Company incurred a net loss of $8.24 million (August 31, 2021 – net

loss of $ 13.1 million). The current year loss was lower primarily due to reduced interest

expense of $1.7 million versus $5.1 million in fiscal 2021. All of the Company’s $27.8 million

in debt at August 31, 2021 was paid off during fiscal 2022. General and administrative

expenses during the year were lower at $4.3 million (August 31, 2021 - $5.1 million). Share

based compensation was also lower at $2.2 million (August 31, 2021 - $3.2 million). The

foreign exchange gain recognized in the current year was $0.3 million (August 31, 2021 -

$0.7 million gain) due to the to the U.S. Dollar increasing in value relative to the Canadian

Dollar during the current year.

At August 31, 2022, finance income consisting of interest earned and property rental fees in

the year amounted to $0.2 million (August 31, 2021 - $0.1 million). Loss per share for the

year amounted to $0.09 as compared to a loss of $0.18 per share for fiscal 2021.

Accounts receivable at August 31, 2022 totalled $0.4 million (August 31, 2021 - $0.3 million)

while accounts payable and other liabilities amounted to $1.1 million (August 31, 2021 - $2.5

million). Accounts receivable was comprised mainly of value added taxes repayable to the

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

engineering and maintenance costs on the Waterberg Project.

In June 2022, the Company completed an at-the-market equity program (the “2021 ATM”)

initiated in February 2021. In aggregate, the Company sold 10,426,632 Common Shares in

the 2021 ATM at an average price of $2.94 for gross proceeds of $30.6 million , of which

7,923,642 Common Shares at an average price of $2.48 were sold in fiscal 2022.

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

were approximately $3.0 million (August 31, 2021 - $3.7 million). At year end, $40.4 million

in accumulated net costs was capitalized to the Waterberg Project (August 31, 2021 - $44.0

million). Total expenditures on the property since inception to August 31, 2022 are

approximately $80.9 million.

Outlook

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

and construction decision. PTM is the operator of the Waterberg Project as directed by a

technical committee comprised of representatives from joint venture partners Impala

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

Japan Organization for Metals and Energy Security (formerly Japan Oil, Gas and Metals

PLATINUM GROUP METALS LTD. …5

National Corporation) (“JOGMEC”) and Hanwa Co., Ltd. (“Hanwa”). Before project financing

and a construction decision can be undertaken, arrangements will be required for project

concentrate offtake or processing.

On October 1 8, 2022, Waterberg JV Co. approved in principle the pre-construction Work

Program of approximately $21.0 million over a 23-month period ending August 31, 2024. The

Work Program will focus on project infrastructure including initial road access, water supply,

essential site facilities, a first phase accommodation lodge, a site construction power supply

from state utility Eskom and advancement of the Waterberg Social & Labour Plan. An update

to the 2019 Waterberg Definitive Feasibility Study (“DFS Update”) is also planned, including

a review of cut -off grades, mining methods, infrastructure plans, scheduling, concentrate

offtake, dry stack tailings, costing and other potential revisions to the project’s financial

model.

From the Work Program the Initial Budget of approximately $2.5 million was approved for

expenditure by March 31, 2023, and this work has now commenced. The Initial Budget

includes an infill drilling program targeting near surface, modelled Inferred Mineral Resource

blocks that have good potential for conversion to higher confidence levels, thereby allowing

them to be added to early mine plans, potentially reducing early capital expenditure and the

period to first mining. The infill drill program has commenced and is planned to consist of 16

T Zone NQ boreholes and 16 F Zone NQ boreholes. Mineralized material recovered from the

drill program will be assayed and the remaining material will be processed to determine dry-

stack tailings characteristics and provide additional concentrate meta llurgical data. If dry

stack tailings methods are implemented in the DFS Update, it is expected that mine water

consumption will be reduced by 40% to 50%.

The Initial Budget for the Work Program is to be funded pro rata by the joint venture partners

and was coordinated to match fiscal year and budgetary periods for JOGMEC and Hanwa.

Subsequent expenditures in accordance with the Work Program are subject to expected

approvals for sequential time periods ending on August 31, 2024.

The Company continues to w ork closely with regional and local communities and their

leadership on mine development plans to achieve optimal outcomes and best value to all

stakeholders.

The Company is considering commercial alternatives for mine development, financing and

concentrate offtake. Obtaining reasonable terms for Waterberg concentrate offtake from an

existing smelter/refiner in South Africa is considered the preferred option and discussions with

such parties are ongoing. As an alternative to a traditional concentrate offtake arrangement,

studies are also underway to assess the economic feasibility of constructing a matte furnace

and base metal refinery to process Waterberg concentrate. The NI 43-101 definitive feasibility

study technical report for the Wat erberg Project entitled “Independent Technical Report,

Waterberg Project Definitive Feasibility Study and Mineral Resource Update, Bushveld

Complex, South Africa” dated October 4, 2019, stated that “Additional smelting capacity may

need to be constructed i n the industry to be able to treat the flotation concentrate from

PLATINUM GROUP METALS LTD. …6

Waterberg and the other potential Platreef miners.” A matte furnace and base metal refinery

as described above is envisioned as a separate business from Waterberg JV Co. that could

provide concentrate offtake terms to Waterberg JV Co. and possibly to other PGM miners.

Discussions with potential participating partners and investors have occurred and are planned

for the future.

As the world seeks to decarbonize and look for solutions to clim ate change, the unique

properties of PGMs as powerful catalysts are being applied to various technologies as possible

solutions for more efficient energy generation and storage . The Company’s battery

technology initiative through Lion with partner Anglo r epresents 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 Lion 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.

Environmental, Social and Governance

Platinum Group recently received its second annual Environmental, Social and Governance

(“ESG”) disclosure report from Digbee Ltd. (“ Digbee”), a United Kingdom based company

that has developed an industry standard ESG disclosure framework for the mining sector

providing a right -sized, future looking set of frameworks against which they can credibly

disclose, track, compare and improve their ESG performance. Digbee ESG has been

developed in consultation with mining companies, ESG specialists and capital providers and
