Platinum Group Metals Reports Positive Metallurgical Test Results for Waterberg

VANCOUVER, BRITISH COLUMBIA and JOHANNESBURG, SOUTH AFRICA--(Marketwired - May 15, 2013) - Platinum Group Metals Ltd. (TSX:PTM)(NYSE MKT:PLG) ("Platinum Group" or "the Company") announces positive initial test results from metallurgical samples of the "T2" and "F" zones from the Waterberg platinum deposit. Estimated recoveries for platinum, palladium and gold in scoping flotation tests completed in South Africa at SGS Laboratories ("SGS"), averaged 88% for the T2 zone and 83% for the F Zone.

The 10.1 million ounce platinum, palladium and gold Waterberg deposit was initially discovered in November 2011 by the Company and joint venture partners including JOGMEC of Japan. (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

R. Michael Jones, P.Eng, President and CEO of Platinum Group Metals said, "We are pleased with the initial results which are in-line or exceeding our expectations based on the character of the deposit. This is an important component of the preliminary economic assessment of the first block of Waterberg. We also look forward to an updated resource model for the assessment on the first 5.5 kilometers of strike length by August 2013 and the opportunity to explore a further 25 kilometers of untested potential, north from the joint venture property, during 2013 and 2014."

Drilling continues at Waterberg with 15 machines.


The initial composite samples had grades of 3.24 g/t platinum, palladium and gold (2PGE+Au), (1.06 g/t Pt, 2.03 g/t Pd, 0.15 g/t Au), 0.11% Ni, 0.05% Cu from the F layers and 7.22 g/t 2PGE+Au, (2.12 g/t Pt, 3.75 g/t Pd, 1.35 g/t Au), 0.10% Ni, 0.24% Cu from the T2 layer. The mineralized samples were studied by microscopic and X-ray diffraction methods, and then milled and subjected to grinding and scoping flotation.

The T2 Zone has similar characteristics to Bushveld Merensky type deposits and the F Zone is similar to other deposits in the North Limb.

Estimated recoveries from scoping cleaner flotation test work to rougher concentrate are:

T2-Zone F-Zone
2PGE+Au 88% 83%
Total Cu 87% 74%
Total Ni 83% 59%

Final concentrate grades will be determined with further test work to optimize the potential circuits. Additives and balances will be required to reduce silicates in the float and maximize concentrate grades. Mineralogy indicates that the final product grade can be improved without affecting PGE, nickel and copper recovery. The "T2" and "F" materials are both soft and have similar milling characteristics, therefore can be processed using a common milling circuit. This has advantages from a cost and beneficiation perspective.
