Platinum Group Metals Announces an 800 Meter Step Out on the T2 Platinum Layer Intersecting 25.5 Meters Grading 6.4 g/t Platinum, Palladium and Gold

VANCOUVER, BRITISH COLUMBIA and JOHANNESBURG, SOUTH AFRICA--(Marketwired - June 10, 2013) -Platinum Group Metals Ltd. (TSX:PTM) (NYSE MKT:PLG) ("Platinum Group" or the "Company") announces that Hole WB-99 has intersected 25.5 meters of the T2 layer grading 6.4 grams per tonne 3E (1.86 g/t Platinum, 3.20 g/t Palladium and 1.37 g/t Gold, 0.34% copper, 0.17% nickel) over a core length of 25.5 metres at a depth of 681.0 metres to 706.5 metres. Included is a higher grade intercept of 2.5 metres of 12.2 g/t 3E at 698.5 metres to 701.0 metres. This intercept is located 800 meters northeast along strike from the previous intercepts and 300 meters northeast of the blocks in the current T2 layer resources. The assays from WB-99 display the distinctive T layer metal ratios of approximately 29% Platinum, 50% Palladium and 21% Gold. WB-99 is within the JOGMEC joint venture, where the Company holds a 49.9% effective interest.

R. Michael Jones, P.Eng, CEO of Platinum Group Metals said, "This intercept is important because it's high grade, thick, relatively near surface, open up dip, is an 800 meter step out from the most north eastern intercept and it increases the potential of the best grade, best metallurgical recovery layer in the Waterberg deposit. The intercept is in position, at the predicted depth, with the signature 20% gold ratio in the precious metals basket, further confirming it to be T2".

Drilling is continuing with a further 1.7 kilometre northward step out from WB-99, again targeting the T mineralized layers. The WB-99 intercept is estimated to have a true thickness of 20.1 metres and the deposit model is open on strike, up-dip and down-dip. The T1 layer was also intersected in WB-99, adding to the confirmation of deposit continuity.

Prior to hole WB-99 drilling has focused on fill-in drilling on the F layers, at 250 metre spacing, up-dip from the current area of declared F layer mineral resource. An updated table of intercepts from this work is expected shortly. An update to the overall resources at Waterberg including the T and F layers is on track for August 2013. Drill spacing has been selected to allow for potential resource additions on both T and F layers.

The 10.1 million ounce platinum, palladium and gold Waterberg deposit consisting T1, T2, FP and FH layers was initially discovered by the Company and joint venture partners including JOGMEC of Japan. The resource has expanded significantly during 2012. (Current Inferred Resource 93Mt 3.39 g/t 2PGE+Au, 1.03 g/t Pt, 2.02 g/t Pd, 0.34 g/t Au, March 18, 2013 Technical Report on www.sedar.com, Ken Lomberg QP).

A total of 110 holes plus deflections on the mineralized layers have been completed or are in progress to date at the Waterberg Project. The success rate in terms of intercepting the targeted mineralized layers so far is approximately 98%. Metallurgical test work indicates the best flotation recoveries in the Waterberg deposit is from the T2 layer at 88%. T2 also has the best average grade in the deposit and the layer is present from about 130 meters below surface.

Qualified Person, Quality Control and Assurance

The non-independent qualified person for the intercepts reported in this release is R. Michael Jones, P. Eng the Company President. He has more than 20 years of relevant experience and he has verified the data by ensuring that qualified geologists are involved in collection and compilation of the data, and that a system of quality control and chain of custody records are maintained and he has visited the property several times and reviewed the detailed data. He is satisfied with the verification of the data.

Ken Lomberg is the independent qualified person for the resources on the Waterberg Deposit and he has reviewed the references to resources in this press release.

Quality control and assurance was completed in the normal process for Platinum Group Metals RSA Pty Ltd. Standards, duplicates and blanks were inserted regularly in every assay batch. These assay results were checked and any results outside of two standard deviations were re-assayed. Strict control and documentation on the core from the drill rig to the site and the assay samples to the lab were maintained at all times under a chain of custody sign off system. The platinum group elements were assayed by fire assay using a nickel sulphide collection method at Setpoint Laboratories, Johannesburg, a SANAS accredited laboratory. Base metals and other major elements were determined by multi acid digestion with ICP finish.
