Platinum Group Metals Updates the Waterberg Joint Venture and Waterberg Extension Projects

New Intersections include 80 meters grading 4.80 g/t 3E

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Oct 21, 2014) - Platinum Group Metals Ltd. (TSX:PTM)(NYSE MKT:PLG) ("Platinum Group Metals" or the "Company") announces the completion of approximately 71,000 meters of vertical core drilling on budget at the Waterberg Joint Venture and Waterberg Extension projects (collectively the Waterberg Projects) since June 2014 utilizing 24 machines. The drilling program has been successful at expanding and detailing the Waterberg T, F and Super F Zones as part of an ongoing Pre-Feasibility Study. Waterberg represents a new deposit type in the Northern Limb of Bushveld Complex of South Africa amenable to mechanized mining.

Intercepts include hole WB123 on the Waterberg Joint Venture property returning an 80 meter intercept of 4.80 g/t 3E (1.41 g/t platinum, 3.18 g/t palladium, 0.21 g/t gold, 0.10 % Cu and 0.23 % Ni) from 370 to 450 meters. The true thickness of this intercept is estimated at 63 meters. Rhodium determinations are pending. This hole is up-dip of the previously defined "Super F" Zone and further drilling shallower along the layer is in progress. Also included in the Super F Zone in-fill holes, within the area of the June 2014 resource estimate, is hole WB161, on the Waterberg Joint Venture property and announced here, which intersected 46.79 meters of 3.76 g/t 3E (1.06 g/t platinum, 2.51 g/t palladium, 0.19 g/t gold, 0.10 % Cu and 0.19 % Ni). The true thickness of this intercept is estimated at 37 meters. The core Super F Zone from the Waterberg Joint Venture resource area has been confirmed and expanded.

Highlights from the confirmation drilling on the T Zone include hole WB126 on the Waterberg Joint Venture which returned a 9 meter intercept of 6.23 g/t 3E (1.61 g/t platinum, 3.64 g/t palladium and 0.98 g/t gold) from 236 to 245 meters. Lithological and grade continuity has been confirmed with this drilling program.

There are approximately 6,000 assays outstanding from the ongoing drilling program.

A new T Zone intersection in hole WE048 on the Waterberg Extension (Waterberg II) returned a 2.9 meter intercept of 3.12 g/t 3E (0.88 g/t platinum, 2.10 g/t palladium and 0.14 g/t gold). This intersection confirmed the extension of the T Zone towards the north.

The Waterberg III area on the Waterberg Extension property has now been confirmed by drilling as a target area for extension of the Waterberg mineralized zones. Approximately 1.9 kilometers north of the current resource, both the T Zone and F Zone have been confirmed in a single borehole, (WE046) with a lower grade F Zone intercept including 2.5m at 2.00 g/t 3E (0.61 g/t platinum, 1.33 g/t palladium, 0.06 g/t gold). The T zone at this location was geochemically elevated only and the zone was identified in rock types. The geological model for Waterberg indicates that low grade zones do occur. The presence of the Waterberg deposit northward onto the Waterberg III (Waterberg Extension) area is a positive development. Deflections are in progress on this first Waterberg III drill hole. Based on a reinterpretation of airborne gravity surveys, taking into consideration the latest drill hole results, additional drilling along strike is planned.

Pre-Feasibility Study On Track

An updated resource estimate for Waterberg is to be completed by Coffey prior to the completion of updated mine and project designs for the ongoing Pre-Feasibility Study. Engineering firm DRA has commenced work and is on track with the Pre-Feasibility Study. The Pre-Feasibility Study is funded by the Company and Waterberg Joint Venture partner JOGMEC and is targeted for completion in calendar Q2 2015. The study of expanded opportunities considering the implications of the resources beyond the Waterberg Joint Venture on to the Waterberg Extension, downstream smelter options, synergies with regional projects and marketing have been added to the scope of the Pre-Feasibility Study. DRA and other specialists will work closely with JOGMEC metallurgists with regard to concentrator processes and concentrate specifications. Specialists on power, water and other infrastructure are also involved in the Pre-Feasibility Study and have identified options for bulk infrastructure requirements.

As a result of the expansion of estimated platinum group element resources from 17 million ounces to 29 million ounces in June 2014, (Inferred, 287 million tonnes grading 3.15 g/t 4E (0.94g/t Pt, 1.92 g/t Pd, 0.04 g/t Rh, 0.25 g/t Au)) the Preliminary Economic Assessment for the Waterberg Projects is outdated and no longer valid and the current NI 43-101 technical report for the Waterberg Projects is the updated resource report filed on July 25, 2014. The resource was announced June 12, 2014 and was prepared by Kenneth Lomberg, B.Sc. (Hons) Geology, B. Com., M. Eng. Pr.Sci.Nat. and Alan Goldschmidt, Pr.Sci.Nat., of Coffey Mining (South Africa) Pty Ltd

The Company looks forward to the advancement and further exploration of the Waterberg Projects.

Further assay results are being compiled as they are received. The current inferred resource at the Waterberg Projects is 29 Million ounces of platinum, palladium, rhodium and gold, ("4E") in the "T" and "F" layers. (287 million tonnes grading 3.15 g/t 4E (0.94 g/t Pt, 1.92 g/t Pd, 0.04 g/t Rh, 0.25 g/t Au,) 30%, 61%, 1%, 8% respectively). Inferred resources do not have demonstrated economic viability and see other cautions to investors.

Qualified Person, Quality Control and Assurance

The non-independent qualified person for this Press Release is R. Michael Jones P.Eng. He has relevant experience in precious metals and platinum evaluations and has verified the data by reviewing the detailed assay and geological information on the Waterberg deposit and visiting the site and core yard many times from 2011 through 2014.

Ken Lomberg of Coffey Mining (South Africa) Pty Ltd is the independent qualified person for the mineral resources on the Waterberg Projects and he has reviewed the references to resources and ongoing work in this press release. It is planned that Coffey Mining will prepare an update on the mineral resource for the Pre-Feasibility Study based on the current ongoing in-fill drilling.

Base metals and other major elements were determined by multi acid digestion with ICP finish and PGEs were determined by conventional fire assay and ICP finish. Setpoint Laboratories is an experienced ISO 17025 SANAS accredited laboratory in assaying and have utilized a standard quality control system including the use of standards. Platinum Group Metals utilized a well-documented system of inserting blanks and standards into the assay stream and has a strict chain of custody and independent lab re-check system for quality control. These standards are detailed in the July 25, 2014 Technical Report referred to above.

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 Prospecting Rights 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.

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

The disclosure in this press release regarding mineral properties was prepared in accordance with Canadian National Instrument 43-101 ("NI 43-101"), which differ significantly from the mineral reserve disclosure requirements of the U.S. Securities and Exchange Commission ("SEC") set out in Industry Guide 7.Under NI 43-101, companies are permitted and required to disclose "mineral resources", which are not "reserves". U.S. companies subject to the disclosure requirements of the SEC are not normally permitted to disclose mineralization unless they constitute "reserves" by U.S. standards in documents filed with the SEC. Investors are specifically cautioned not to assume that any part or all of "measured mineral resources", "indicated mineral resources" or "inferred mineral resources" will ever be converted into SEC defined mineral reserves. "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" exist or 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. In addition, the definitions of "reserves" and related terms under NI 43-101 and the SEC's Industry Guide 7 differ significantly. Accordingly, any "reserves" disclosed in this press release may not constitute "reserves" under SEC standards. Under SEC standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Among other things, all necessary permits would be required to be in hand or issuance imminent in order to classify mineralized material as reserves under the SEC standards. Further, while NI 43-101 permits companies to disclose the economic projections contained in preliminary economic analyses and pre-feasibility studies, which are not based on "reserves", U.S. companies are not normally permitted to include such economic projections in their SEC filings prior to the establishment of reserves under SEC standards. For the above reasons, statements contained in this press release that describes mineral reserve and resource estimates or that describes the results of preliminary economic analyses or pre-feasibility studies are not comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements of the SEC.
