Platinum Group Metals And Capricorn Municipality To Work

Together On Water Supply Management

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

(“Platinum Group” , “PTM” or the “Company”) Metals is pleased to announce that

Waterberg JV Resources (Pty) Ltd. (“Waterberg JV Co.”), the operating company of the

Waterberg Joint Venture, has entered into an agreement with the Capricorn District

Municipality to jointly develop a water supply management plan to increase the water

supply and infra structure capacity for both local community and Waterberg Mine usage.

This public-private partnership will benefit both the mine and the communities around the

mining area.

Capricorn District Municipality has identified ground water resources proximal to the newly

discovered Waterberg bulk minable palladium-platinum-gold and rhodium project. At the

pre-feasibility stage independent specialists identified potential water resources for both

the mine and local communities. The joint responsible management of the water

resources is the objective of the agreement.

An earlier, well executed work and drilling program conducted by the Capricorn District

Municipality identified both potable and high mineral unpotable water resources in the

district. Work by Waterberg JV Co. has also identified some potable water resources. The

unpotable water is now targeted for industrial use and potable water could then be

prioritized for communities.

Working together the parties can ensure the best value and use of the district water

resources, including for communities, businesses and the Waterberg Mine. Waterberg JV

Co. has the requisite skills, expertise and resources to provide water supply solutions in

the Capricorn District Municipality and to implement an agreed water management plan.

R. Michael Jones CEO of Platinum Group s aid, “We see this as an important step in the

development of a large -scale palladium mine in Capricorn District Municipality to the

benefit of all stakeholders including shareholders, communities and all levels of

government.”

Executive Mayor John Mosima Mpe of Capricorn Municipality said, “We are very pleased to

see the potential for responsible, efficient and effective management of water in the

region to the benefit of all of our people. We are focussed on the economic benefits of job

creation and water delivery in our area while being mindful of being good caretakers of all

the resources in the region for all stakeholders. We look forward to working co-operatively

with Waterberg JV Co.”

The Waterberg Project is a large-scale mine development in the North Limb that will utilize

modern, safe and fully mechanized mining. The thickness of the orebody allows for a

change from conventional narrow reef mines in South Africa. Waterberg is also different

than other mines in South Africa as it is dominated by pa lladium. The Pre-feasibility study

envisaged a 19 -year mine life. The partners in Waterberg JV Co. are Platinum Group

Metals Ltd, Impala Platinum Holdings Ltd., Mnombo Wethu Consultants (Pty) Ltd. and

Japan Oil, Gas and Metals National Corporation (“JOGMEC ”), a Japanese Incorporated

Administrative Agency. Japanese trading house Hanwa Co., Ltd. is in process of buying

an interest in the project from JOGMEC as well. A definitive feasibility study is in progress

on the large -scale reserves and engineering fo r infrastructure, including water is part of

that study, expected to be completed in the first part of 2019.
