Platinum Group Metals Ltd. Receives Final Government

Approval For Maseve Mine Sale

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

(“Platinum Group” “PTM” or the “ Company”) reports that government approval has been

received for Royal Bafokeng Platinum Limited (“RBPlat”) to acquire 100% of the shares in

Maseve Investments 11 (Pty) Ltd. , the holding company of the Maseve Mine, and all

shareholder loans owed by Maseve , for an aggregate consideration in cash and RBPlat

common shares, valued on September 6, 2017 at approximately US$16 million.

The South African Department of Mineral Resources (“DMR”) has granted consent in terms

of section 11 of the Mineral and Petroleum Resources Development Act to transfer the entire

issued share capital in Maseve held by the Company and one minority shareholder to RBPlat.

Maseve is the holder of the mining right underlaying the Maseve Mine. With the grant of

section 11 approval all conditions precedent to the completion of the sale of Maseve to

RBPlat (the “Maseve Sale Transaction”) have now been met.

Platinum Group CEO R. Michael Jones said “ The Board of Directors of Platinum Group

appreciate the DMR’s timely approval. The sale of the Maseve Mine is important for Platinum

Group to reduce debt and allow us to focus on our large -scale bulk, Waterberg palladium

discovery. RB Plat will be able to preserve jobs and combine Maseve with their adjacent

operations. ”

The Company and RBPlat announced a term sheet for a two-step sale transaction valued at

approximately US$74 million on September 6, 2017. Later, on November 23, 2017 ,

definitive agreements were executed1. On April 5, 2018 Maseve completed the sale of the

Maseve concentrator plant and certain surface rights (“Step One”) to RBPlat for cash

consideration. RBPlat will now acquire 100% of the shares (“Step Two”) in Maseve, the

holding company of the Maseve Mine, and all shareholder loans owed by Maseve, for an

aggregate consideration in cash and RBPlat common shares, valued on September 6, 2017

at approximately US$16 million ( approximately US$15.45 million at present ) of which

approximately US$854,935 (approximately US$755,378 at present) is to be paid in RBPlat

common shares to a minority shareholder of Maseve.

The Company intends to pay all of its net proceeds from Step Two, which may take several

months to be fully realized into cash, to reduce outstanding indebtedness pursuant to a

secured loan facility (the “LMM Facility”) with Liberty Metals & Mining Holdings, LLC (“LMM”).
