million pre-construction work program approved in principle for the Waterberg Project by the

directors and shareholders of Waterberg JV Co. on October 18, 2022.

On December 5, 2024, the Company entered into an Equity Distribution Agreement with

BMO Nesbit Burns Inc. and Beacon Securities Limited (the “Canadian Agents”) and BMO

Capital Markets Corp. (the “ U.S. Agent ” and together with the Canadian Agent s, the

“Agents”) for a new at -the-market equity program (the “ 2025 ATM”) to distribute up to

$50.0 million (or the equivalent in Canadian dollars) of Common Shares (the “ Offered

Shares”). The Offered Shares will be issued by the Company to the public from time to time,

through the Agents, at the Company’s discretion. The Offered Shares sold under the 2025

ATM will be sold at the prevailing market price at the time of sale. The net proceeds of any

such sales will be used for the Waterberg Project pre-construction site work, engineering and

preparation, a potential phase one development program at the Waterberg Project, a Saudi

Arabia smelter and base metal refinery definitive feasibility study, a contingency provision

and general, corporate and administrative expenses.

During the three months ended February 28, 2025 , the Company issued 842,561 Common

Shares, through BMO Capital Markets on the NYSE American pursuant to the 202 5 ATM, at

an average price of $1.35 per share, for gross proceeds of $1.14 million. Directly attributable

expenses paid to the U.S. Agent , totaled $0.03 million during the three months ending

February 28, 2025. After February 28, 2025, to the date of this news release, the Company

sold and issued a further 732,726 Common Shares pursuant to the 2025 ATM at an average

price of $1.25 per share, for net proceeds of $0.90 million.

On November 26, 2024, the Company entered a memorandum of understanding (“MOU”)

with Ajlan & Bros Company for Mining, a subsidiary of Ajlan & Bros Holding (“ Ajlan”), and

the Ministry of Investment of Saudi Arabia (“ MISA”) as a part of the Global Supply Chain

Resilience Initiative, for the setup of a proposed platinum group metals smelter (“ PGM

Smelter”) and base metal refinery (“BMR”) to be located in Saudi Arabia. Ajlan is one of the

largest private sector diversified conglomerates in the Middle East. Earlier, in December 2023,

Ajlan and the Company entered into a Cooperation Agreement (as defined below) to study

the establishment of a stand-alone PGM Smelter and BMR in Saudi Arabia. According to the

PLATINUM GROUP METALS LTD. …3

4898-4095-8772\2

terms of the MOU, MISA will offer strategic guidance and study potential financial support to

the proposed PGM Smelter and BMR and the Waterberg Project located in South Africa.

On November 13, 2024, the Company filed a final short form base shelf prospectus (the

“Shelf Prospectus”) with the securities regulatory authorities in each of the provinces and

territories of Canada and a corresponding registration statement on Form F -10 (the

“Registration Statement”) with the U.S. Securities and Exchange Commission (“SEC”),

under the Multijurisdictional Disclosure System established between Canada and the United

States. Pursuant to the Shelf Prospectus and the Registration Statement, the Company may

offer and sell Common Shares, debt securities, warrants, subscription receipts, or a

combination thereof up to an aggregate initial offering amount of $250 million (or its

equivalent in Canadian dollars) from time to time, separately or together, in amounts, at

prices and on terms to be determined based on market conditions at the time of the offering

and as set out in an accompanying prospectus supplement, during the 25-month period that

the Shelf Prospectus and the Registration Statement remain effective.

On September 16, 2024 , the Company reported positive results from an Independent

Definitive Feasibility Study Update ( the “ Waterberg DFS Update”) for the Waterberg

Project. The associated technical report entitled “Waterberg Definitive Feasibility Study

Update, Bushveld Igneous Complex, Republic of South Africa”, with an effective date of August

31, 2024 , was filed on SEDAR+ on October 9, 2024. The Waterberg DFS Update was

prepared by independent qualified persons in accordance with Canadian National Instrument

43-101 Standards of Disclosure for Mineral Projects (“ NI 43-101”) and Subpart 229.1300

and Item 601(b)(96) of the SEC's Regulation S-K (collectively, “S-K 1300”). The Waterberg

DFS Update included revised mineral resource and mineral reserve estimates. For details of

the Waterberg DFS Update see the Company’s news release dated September 16, 2024, the

MD&A, and the technical report referred to above.

Results For The Six Months Ended February 28, 2025

During the six months ended February 28, 2025, the Company incurred a net loss of $2.25

million (February 28, 2024 – net loss of $2.37 million). General and administrative expenses

during the period were higher at $2.0 million (February 28, 2024 - $1.82 million) due to legal

costs related to the Shelf Prospectus, the Registration Statement, the 2025 ATM, the

completion of the Waterberg DFS Update, and a reimbursement of legal costs in the previous

comparable period. Stock based compensation was lower at $0.45 million in the current

period (February 28, 2024 - $0.59 million) due to the revaluation of outstanding deferred

share units in the current period. The foreign exchange gain recognized in the current period

was $0.15 million (February 28, 2024 - $0.03 million gain) due primarily to the U.S. Dollar

increasing in value relative to the Canadian Dollar during the period.

At February 28, 2025, finance income consisting of interest earned in the six month period

amounted to $0.10 million (February 28, 2024 - $0.25 million). Basic and diluted l oss per

share for the six months ended February 28, 2025, amounted to $0.02, which was also $0.02

per share for the comparable period ended February 28, 2024.

PLATINUM GROUP METALS LTD. …4

4898-4095-8772\2

Accounts receivable at February 28, 2025, totalled $0.18 million (August 31, 2024 - $0.23

million) while accounts payable and other liabilities amounted to $ 0.69 million (August 31,

2024 - $0.91 million). Accounts receivable was comprised primarily of value added taxes

repayable to the Company in South Africa. Accounts payable consisted primarily of

professional fees payable in relation to the preparation and filing of the Shelf Prospectus, the

Registration Statement and the 2025 ATM, as well as for project engineering and maintenance

costs on the Waterberg Project.

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

months ended February 28, 2025, were approximately $ 1.0 million (February 28, 2024 -

$1.63 million). At period end, $45.9 million in accumulated net costs were capitalized to the

Waterberg Project. Total expenditures on the property since inception to February 28, 2025,

are approximately $90.1 million.

For more information on mineral properties, see Note 3 of the Financial Statements.

Smelting and Refining Update

On December 20, 2023, the Company announced a Cooperation Agreement (the

“Cooperation Agreement”) with Ajlan to study the establishment of a stand -alone PGM

Smelter and BMR in Saudi Arabia. The Cooperation Agreement encompasses three phases:

a global PGM concentrate market study (the “Market Study”), a Definitive Feasibility Study

for the construction and operation of the PGM Smelter and BMR in Saudi Arabia (the “Smelter

DFS”), and an option to form an incorporated 50:50 joint venture following the completion of

the Smelter DFS.

An initial trade -off study was completed in mid 2023 to first determine the viability of

exporting PGM concentrate from South Africa to Saudi Arabia. The Market Study was

completed in late 2024 by a globally recognized consulting group specializing in PG Ms and

associated base metal by-products. Based on the analysis, the combination of concentrate

from the Waterberg Project and end of life auto catalysts and petrochemical catalysts, sourced

from the Gulf Region, could justify the scale required to construct a long term PGM smelting

and refining complex in Saudi Arabia. Other sources of mined PGM concentrate from Southern

Africa could be considered over the longer term. Sources beyond South ern Africa are

considered to o early stage, too low in PG M content and too far away to be transported

economically.

The Smelter DFS was to assume the export of PGM concentrate from the Waterberg Project

in South Africa to a port facility in Saudi Arabia and w as to encompass options related to

infrastructure, location, technical specifications, capital, and operating costs. All expenses

related to the Smelter DFS, expected to cost approximately $4.0 million, were to be split on

a 50:50 basis between Platinum Group and Ajlan, including certain costs already incurred by

Platinum Group in previous independent beneficiation studies.

PLATINUM GROUP METALS LTD. …5

4898-4095-8772\2

A key requirement for the above proposal to establish a PGM Smelter and BMR in Saudi Arabia

would be a long-term South African government approval for the export of unrefined precious

metals in concentrate. Platinum Group has been working with the Government of South Africa

to identify local beneficiation opportunities and to analyze the possible impact of exporting

concentrate on the value chain. Through these discussions the government of South Africa

has expressed their preference and support for beneficiation in South Africa. As a result,

Ajlan and PTM are also now studying the possibility of establishing a matte furnace in South

Africa capable of smelting Waterberg Project concentrate. Such a facility would ideally be

located near the Waterberg Project with existing power, water and environmental

authorizations. The converter matte produced would be shipped to Saudi Arabia for further

processing through a BMR , at which time spent auto catalysts and other PGM bearing

materials could be co-processed.

The Company and Ajlan are currently conducting a trade off study and developing a scope of

work and cost estimate for the engineering studies required to assess the above scenario ,

should it be chosen as the primary plan . One noteworthy consideration would be the much

lower volume of material to be shipped to Saudi Arabia. Rather than shipping up to 130,000

tonnes of concentrate a year, or approximately fourteen concentrate trucks a day, the volume

of converter matte to be shipped would be reduced to approximately 8,000 tonnes a year, or

approximately one truck a day.

Outlook

The Company’s primary 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

Implats, Mnombo, and HJM.

Since October 18, 2022, Waterberg JV Co. has been advancing exploration and engineering

work related to the Waterberg DFS Update, initial road access, water supply, infrastructure

and 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.

Engagement with local communities has been ongoing and together the parties have agreed

upon the location of project facilities and infrastructure.

Before a construction decision can be undertaken , arrangements will be required for

Waterberg Project concentrate offtake or processing. The Company and Waterberg JV Co.

are assessing commercial alternatives for mine development financing and concentrate

offtake. In addition to the Company’s investigation of smelting and base metal refining

options in Saudi Arabia (as described above), the Company is also in discussion with several

South African smelter operators, including Implats, with a view to negotiating formal

concentrate offtake arrangements for the Waterberg Project.

PLATINUM GROUP METALS LTD. …6

4898-4095-8772\2

The Company continues to work closely with regional and local communities and their

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

stakeholders.

As the world seeks to decarbonize and look for solutions to climate change, the adoption of

battery electric vehicles is forecast to reduce the future demand for PGMs used in

autocatalysis. T he unique properties of PGMs as powerful catalysts are being applied to

various technologies as possible solutions for more efficient energy generation and storage,

which may create new demand for PGMs . The Company’s battery technology initiative

through Lion with partner Amplats represents one such 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 and lithium-sulfur battery chemistries.

Although platinum and palladium are exempt, as they are considered critical minerals, the

new global tariffs recently announced by the United States administration in Washington, DC,

layered on top of previously announced tariffs on automobiles, steel, aluminum, etc. , have

raised uncertainty regarding markets in general and specifically to the production and sale of

automobiles and light duty vehicles. A period of uncertainty is likely as investors and

consumers consider the impact of these tariffs, and as the level of retaliation and market

diversification by other nations becomes apparent.
