Platinum Group Metals Ltd.: 10 Million Ounce Platinum, Palladium and Gold
Inferred Updated Mineral Resource at Waterberg

VANCOUVER, BRITISH COLUMBIA and JOHANNESBURG, SOUTH AFRICA--(Marketwire - Feb.
1, 2013) - Platinum Group Metals Ltd. (TSX:PTM)(NYSE MKT:PLG)(NYSE Amex:PLG)
("Platinum Group" or the "Company") announces an updated 10 million ounce 3E
(Platinum, Palladium and Gold) inferred mineral resource estimate for the
Waterberg joint venture property. The current resource covers only 250m of
influence up dip and eastward into a new permit granted in January 2013. The
deposit remains open along strike onto permits under application as well as
up-dip. Drilling continues and has been ramped up from 10 to 15 drill rigs,
largely focused on the up-dip potential of the deposit.

Overall with drilling in late 2012 the estimated resource has been expanded by
51%. The total deposit grade has increased slightly and the average thickness
has increased from 4.1 meters to 4.6 meters thick on the four layers in the
resource estimate. The metal ratios of platinum, palladium and gold have
remained generally consistent with initial resource estimate in 2012. 

The total resource contains 10.12 million ounces platinum, palladium and gold
(3E) in 92.93 million tonnes with the shallowest part of the deposit in the T
zone at 124 meters deep and the deposit cut off at 1000m deep as a preliminary
economic cut off. The updated inferred mineral resource estimate covers the
first 2.8 kilometres of T-zone and 5.4 kilometres of F-zone strike length.

Inferred Mineral Resource, Dated February 01, 2013, Ken Lomberg, Coffey
Mining, Independent Qualified Person

Based on drilling to date, an interpreted erosional feature of the Waterberg
sediments into the newly discovered lobe of the Bushveld complex limits part
of the eastern T zone extension near surface. Additional T zone potential is
open to the west and north of the current area of drilling. "F" zone
exploration drilling from approximately 300 meters deep up-dip towards surface
is ongoing.

The inferred mineral resource estimate includes two "T" and two "F"
mineralized layers. The most important layers are the 4.1 meter thick "T2" and
5.5 meter thick "FP" layers. The T layers are very well correlated in terms of
geochemical markers and lithology and have a characteristic metal split of
approximately 50% Palladium, 29% Platinum and 21% Gold. The F layers are
approximately 5.2 metres thick on average, having an approximate metal split
of 65% Palladium and 31% Platinum and 4% Gold. 

The Waterberg deposit has excellent potential to be mined by highly efficient
mechanized methods and the initial deposit depth are amenable to a decline
ramp rather than vertical shafts.

For the initial and the current resource models the T and the F layers have
been modelled to a cut-off depth of 1,000 metres below surface. Mineralization
below this depth has not been included in the current resource estimate.
Significant mineralized intercepts have been returned below this depth, up to
1,300 meters deep. The 1,000 metre cut-off depth will be re-evaluated during a
preliminary economic assessment planned for 2013. 

Platinum Group, with a 49.9% direct and indirect interest in the Waterberg
property, made the discovery in partnership with the Japan Oil, Gas and Metals
National Corporation ("JOGMEC"). JOGMEC holds a direct 37% interest in the
Waterberg property with a balance of approximately 13.1% of the project being
held by black empowerment interests. Platinum Group is the operator of the
project. JOGMEC has now approved their participation in an initial USD $10.0
million exploration program for 2013. 

R. Michael Jones, President and CEO of Platinum Group, said "The Waterberg
discovery of near surface, thick platinum is very opportune at a time of
shrinking global production of platinum from the conventional mines. As we
continue to drill for resource expansion we will commence a preliminary
economic assessment on the initial 10 million ounces. Our teams have now
completed the design of the WBJV Project 1 mine now in construction, and are
excited to begin their work on initial mine designs for Waterberg". 

Inferred Mineral Resource Estimate Details

The mineral resource estimate was completed by Ken Lomberg (SACNAPS 400038/01)
of Coffey Mining. Coffey Mining is a well-established international Mining
consultancy with offices in Australia, Africa, North America and South
America.

The inferred mineral resource estimate was prepared using an inverse distance
squared approach and a seam model for each layer. Some 20 boreholes and a
total of 106 intersections on the different layers for the T zone and 30
Boreholes and a total of 101 intersections on the F zone were used in
calculating the inferred mineral resource estimate. 

The basis of the estimates are the identified cuts of the layers. The layers
were initially defined based on their geochemical signatures and checked
against the core to ensure continuity especially between deflections of the
same boreholes. The cuts were also defined based on the geology and marginal
cut-off grade of 0.1g/t PGM, 3E and a minimum thickness of 2 meters. 

A cut-off grade of 2.0g/t was applied to the block model for the T1 and FH
Layers. Note: Totals may not sum exactly due to rounding

Qualified Person, Quality Control and Assurance, Verification

Ken Lomberg is the Independent (as defined in NI-43-101) Qualified Person
("QP") for the inferred mineral resource estimate presented here and he has
approved this disclosure. He is based in South Africa and has 27 years of
relevant experience in resource estimation and mining project evaluations in
many platinum projects and mines. He has verified the data by visiting the
project site, reviewing the core, checking the assay data, checking resource
model cuts on the core, viewing the assay certificates on a test basis and
assisting with the geology interpretation, and reviewing the 3-D deposit model
generated in Datamine by Thys Botha, the non-independent qualified resource
estimation geologist and Exploration Manager for Platinum Group Metals RSA Pty
Ltd. Mr. Lomberg is satisfied that the confidence of the data, the geological
interpretation and estimate are sufficient for the calculation of an inferred
mineral resource estimate. 

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. 

Inferred mineral resource estimates, under the CIM guidelines, do not have
demonstrated economic viability and may never achieve the confidence to be
mineral reserve estimates or to be mined. An inferred resource has reasonably
assumed continuity based on limited sampling but the geological and grade
continuity has not been verified. The property is held under a Prospecting
Right with the exclusive right to convert that right to a Mining Right. There
can be no assurance that a Mining Right will be granted with-out extensive
further work and an Application to the Department of Mineral Resources of
South Africa.

Canadian securities laws and forward-looking statements within the meaning of
U.S. securities laws ("forward-looking statements"). Forward-looking
statements are typically identified by words such as: believe, expect,
anticipate, intend, estimate, plans, postulate and similar expressions, or are
those, which, by their nature, refer to future events. All statements that are
not statements of historical fact are forward-looking statements.
Forward-looking statements in this press release include, without limitation,
statements regarding the Company's plans to move Waterberg ahead with
exploration and engineering work. In addition, the results of the UFS may
constitute forward-looking statements to the extent that they reflect
estimates of mineralization, capital and operating expenses, metal prices and
other factors. Although the Company believes the forward-looking statements in
this press release are reasonable, it can give no assurance that the
expectations and assumptions in such statements will prove to be correct. The
Company cautions investors that any forward-looking statements by the Company
are not guarantees of future results or performance, and that actual results
may differ materially from those in forward looking statements as a result of
various factors, including, but not limited to, variations in market
conditions; the nature, quality and quantity of any mineral deposits that may
be locate;, the Company's ability to obtain any necessary permits, consents or
authorizations required for its activities; the Company's ability to
successfully complete hedging establishment and off-take negotiations; the
Company's ability to produce minerals from its properties successfully or
profitably, to continue its projected growth, or to be fully able to implement
its business strategies and other risk factors described in the Company's Form
40-F annual report, annual information form and other filings with the SEC and

Cautionary Note to U.S. Investors Regarding Estimates of Inferred Mineral
Resources 

This press release uses the terms "inferred mineral resources." We advise U.S.
investors that while these terms are recognized and required by Canadian
regulations, the SEC does not recognize them. "Inferred mineral resources"
have a great amount of uncertainty as to their existence, and great
uncertainty as to their economic and legal feasibility. It cannot be assumed
that all or any part of an "inferred mineral resource" will ever be upgraded
to a higher category. Under Canadian rules, estimates of "inferred mineral
resources" may not form the basis of a feasibility study or prefeasibility
studies, except in rare cases. The SEC normally only permits issuers to report
mineralization that does not constitute "reserves" as in-place tonnage and
grade without reference to unit measures. U.S. investors are cautioned not to
assume that any part or all of an inferred resource exists or is economically
or legally mineable.
