Platinum Group Metals Ltd. Signs Cooperation Agreement with

Ajlan & Bros Mining and Metals Co. to Study a PGM Smelter and

Base Metal Refinery in Saudi Arabia.

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

(“Platinum Group ” or the “ Company”) reports that i t has entered into a Cooperation

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

(“Ajlan”) to study the establishment of a stand-alone platinum group metals (“PGM”) smelter

and base metals refinery (“BMR”) in Saudi Arabia. The Cooperation Agreement encompasses

three phases: a global PGM concentrate market study (the “Market Study”), a D efinitive

Feasibility Study (“DFS”) for the construction and operation of PGM smelter and BMR in Saudi

Arabia, and an option to form an incorporated 50:50 joint venture following the completion

of the DFS. The DFS will assume the export of PGM concentrate from the Waterberg Project

in South Africa to a port facility in Saudi Arabia.

Platinum Group President and CEO Frank Hallam stated, “ The largest impediment to the

development of the Waterberg Project to date has been the need to secure a concentrate

offtake agreement amongst the existing South African based PGM smelters. We are pleased

to work together with Ajlan to explore a smelting and refining facility in Saudi Arabia as a

strategic alternative that may create an exciting path forward. Saudi Arabia offers an

attractive investment climate that includes highly competitive energy costs, a lower taxation

rate, and significant government financing incentives. We look forward to working with Ajlan

towards the establishment of a world class PGM mineral processing hub in Saudi Arabia and

unlocking the potential of the Waterberg Project for all stakeholders , including host

communities, the government of South Africa, and shareholders.”

In order to minimize the risk of sourcing concentrate from only one project , and to attain

scale, a Market Study to be conducted by a third party will be commissioned to identify

potential global sources of PGM concentrate that could augment the processing of Waterberg

Project concentrate. There are currently several PGM and base metal projects globally seeking

offtake and beneficiation solutions.

Upon the completion of the Market Study, and assuming a favourable outcome, Ajlan and the

Company may together commission a DFS for the construction of a PGM smelter and BMR to

process Waterberg Project concentrate and other concentrate feed in Saudi Arabia at an

estimated cost for the DFS of US$4.0 million. The scope for the DFS will encompass options

related to infrastructure, location, technical specifications, capital, and operating costs . All

expenses related to the DFS are to be split on a 50 :50 basis between Platinum Group and

PLATINUM GROUP METALS LTD. …2

Ajlan, including certain costs already incurred by Platinum Group in previous independent

beneficiation studies.

Upon completion of the DFS, Platinum Group and Ajlan will have the option to form an

incorporated joint venture on a 50:50 basis, on terms to be mutually agreed, for the purpose

of financing, constructing, and operating smelting and refining facilities as contemplated in

the DFS. Saudi Arabia offers significant investment incentives and the new incorporated joint

venture would apply for these incentives . Upon formation, t he incorporated joint venture

would then be in a position to offer concentrate offtake terms to Waterberg JV Resources

(Pty) Limited, the owner and operator of the Waterberg Project.

An initial tradeoff study has been complete d to determine the viability of exporting PGM

concentrate from South Africa to Saudi Arabia. Shipping costs are generally offset by lower

energy costs and water costs. The facility would also benefit from existing infrastructure. A

key requirement would be to secure a long -term permit from South Africa for the export 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 possible impact of

exporting concentrate on the value chain.

The Company believes that c onstruction and operation of the Waterberg Project mine

represents a significant foreign direct investment into South Africa with benefits including the

creation of over 1,300 direct jobs, infrastructure development , and foreign exchange

earnings.
