Platinum Group Metals Ltd. Reports Third Quarter 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 nine months ended May 31, 2024, and provides an update and outlook. The Company is

focused on advancing the 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 platinum, palladium, rhodium and gold (“4E”) mine,

including by-product copper and nickel production, 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 including the arrangement of construction financing and concentrate

offtake agreements. The Company is also advancing an initiative through Lion Battery

Technologies Inc. (“ Lion”) using platinum and palladium in lithium battery technologies in

collaboration with Anglo American Platinum Limited (“Amplats”) and Florida International

University (“FIU”).

Recent Events

On April 3, 2024 , the directors and shareholders of Waterberg JV Resources (Pty) Ltd.

(”Waterberg JV Co.”) unanimously approved a $1.35 million stage four budget (the “Stage

Four Budget”) to allow the continuation of work programs underway while finalizing an

update to the Waterberg Project’s 2019 Definitive Feasibility Study (“ DFS Update”). The

Stage Four Budget, covering the period from March 2024 to approximately August 2024, is a

subcomponent of a $21.0 million pre-construction work program (the “ Work Program”)

PLATINUM GROUP METALS LTD. …2

approved for the Waterberg Project by the directors and shareholders of Waterberg JV Co. on

October 18, 2022 . With regard to the Stage Four Budget, Impala Platinum Holdings Ltd.

(“Implats”) advised that its 2023 group wide restriction on capital expenditures remained in

effect and they could not fund their share of current cash calls. In the fourth fiscal quarter of

2024, Implats’ interest is expected to be diluted by a further 0.087% to approximately

14.864%. Platinum Group has elected to fund Implats shortfall and the Company’s direct

interest in Waterberg JV Co. will increase concurrently with Implats dilution. Implats stated

they would consider the funding of subsequent cash calls as future circumstances allow.

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

“Cooperation Agreement”) with Ajlan & Bros Mining and Metals Co. (“Ajlan”) to study the

establishment of a stand -alone PGM smelter (“PGM Smelter ”) and base metal refinery

(“BMR”) in Saudi Arabia. Ajlan is a subsidiary of Ajlan & Bros Holdings, one of the largest

private sector diversified conglomerates in the Middle East . 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.

The Market Study, which is currently in process, will seek to identify potential global sources

of PGM concentrate that could augment the processing of the Waterberg Project concentrate

in Saudi Arabia and minimize the risk of sourcing concentrate from only one project.

Upon the completion of the Market Study, Ajlan and the Company may together commission

the Smelter DFS at an estimated cost of approximately $4.0 million. The Smelter DFS will

assume the export of PGM concentrate from the Waterberg Project in South Africa to a port

facility in Saudi Arabia and will encompass options related to infrastructure, location, technical

specifications, capital, and operating costs. All expenses related to the Smelter DFS are 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.

An initial trade -off study has been completed to determine the viability of exporting PGM

concentrate from South Africa to Saudi Arabia. A key requirement would be to secure a long-

term permit for the export from South Africa of unrefined precious metals in concentrate.

Platinum Group is working with the Government of South Africa to identify local beneficiation

opportunities and to analyze the possibility of exporting concentrate.

On December 11, 2023, the directors, and shareholders of Waterberg JV Co. unanimously

approved a stage three budget of $ 1.62 million (the “Stage Three Budget”) for continued

work on the Waterberg Project covering the period from September 2023 to approximately

February 2024. In conjunction with its approval, Implats advised that due to a restriction on

capital expenditure across their portfolio, it could not fund its 15% share of the Stage Three

Budget. As a result , Implats’ interest in Waterberg JV Co. was diluted to approximately

14.951% during the third fiscal quarter of 2024. Platinum Group elected to fund Implats ’

PLATINUM GROUP METALS LTD. …3

funding shortfall and the Company’s direct interest in Waterberg JV Co. increased concurrently

with Implats’ dilution.

On September 18, 2023 , the Company reported the closing of a non -brokered private

placement of common shares at a price of $1.18 per common share. An aggregate of

2,118,645 common shares were subscribed for and issued to existing major beneficial

shareholder, Hosken Consolidated Investments Limited (“HCI”), through its subsidiary

Deepkloof Limited, resulting in gross proceeds to the Company of approximately $2.5 million

(the “Private Placement”). Closing of the Private Placement allowed HCI to return to more

than a 26% interest in the Company.

On June 21, 2023 , the Company reported that Lion ha d engaged the Battery Innovation

Center (“ BIC”) in Newberry, Indiana , to help drive commercialization efforts for its next

generation platinum and palladium based battery chemistries. Lion is advancing both

proprietary lithium -sulfur and enhanced lithium -ion (NMC) technology using the unique

catalytic properties of platinum and palladium. Under a scope of work, BIC is conducting

independent small and large scale trials to validate Lion’s proprietary platinum and palladium

based electrode composition, slurry, and films in both lithium-sulfur and lithium-ion (NMC811)

coin and pouch cells. Collaboration with BIC will also include additional research and

development focused on improving performance and scale -up with the goal of creating

prototypes for commercialization consideration in 2024. Lion’s target is to develop batteries

with specific energies that are 20% to 100% higher than current technologies while meeting

or exceeding their present cycle lives.

On June 9, 2023, the Company reported that the Japan Organization for Metals and Energy

Security (“ JOGMEC”) and Hanwa Co. Ltd. (“ Hanwa”) ha d established a special purpose

company, HJ Platinum Metals Company Ltd. (“HJM”), to hold and fund their future equity

interests in the Waterberg Project. The combined interests of JOGMEC (12.195%) and Hanwa

(9.755%) were consolidated into a 21.95% interest for HJM going forward, with JOGMEC to

fund 75% of future equity investments into HJM and Hanwa the remaining 25%.

project engineering and maintenance costs on the Waterberg Project.

On July 27, 2022, the Company entered into an Equity Distribution Agreement with BMO

Nesbitt Burns Inc. and BMO Capital Markets for a new at -the-market equity program (the

“2022 ATM”) to distribute up to $50.0 million (or the equivalent in Canadian dollars) of

common shares of the Company. No Common Shares were sold pursuant to the 2022 ATM

prior to August 31, 2022. As of August 31, 2023 , the Company ha d issued 1,089,503

Common Shares, through BMO Capital Markets on the NYSE American pursuant to the 2022

ATM, at an average price of $1.81, for gross proceeds of $1.97 million. Directly attributable

expenses and legal fees to maintain the 2022 ATM in good standing, and for commissions on

equity sales, totaled $0.45 million during fiscal 2023. No Common Shares have been sold to

date in fiscal 2024 pursuant to the 2022 ATM.

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

months ended May 31, 2024, were approximately $2.3 million (May 31, 2023 - $3.5 million).

At period end, $44.1 million in accumulated net costs were capitalized to the Waterberg

Project. Total expenditures on the property since inception to May 31 , 2024 , are

approximately $88.1 million.

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 Wethu Consultants Proprietary Limited (“Mnombo”), and HJM.

On October 18, 2022, Waterberg JV Co. approved in principle the Work Program, including

proposed work on 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. Work to prepare the DFS Update ,

including updated mineral resource and mineral reserve estimates, was also approved and is

currently in process. The DFS Update is to include a review of cut-off grades, mining methods,

infrastructure plans, scheduling, concentrate offtake, dry stack tailings, costing and other

potential revisions to the Waterberg Project’s mine plan and financial model. A draft of the

DFS Update is currently before the joint venture partners for review and approval and is

expected during the fourth fiscal quarter of 2024.

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, the Company is also in discussion with several South African smelter

PLATINUM GROUP METALS LTD. …5

operators, including Implats, with a view to negotiating formal concentrate offtake

arrangements for the Waterberg Project.

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.
