Platinum Group Metals Files Mining Right Application for the Waterberg JV PGM Project

VANCOUVER, British Columbia and JOHANNESBURG, South Africa, Sept. 04, 2018 -- Platinum Group Metals Ltd. (PTM:TSX; PLG:NYSE American) (“Platinum Group” “PTM” or the “Company”) is pleased to announce as project operator that Waterberg JV Resources (Pty) Ltd. (“Waterberg JV Co.”) has filed a Mining Right Application for the large-scale Waterberg PGM Project. The application was submitted to South Africa’s Department of Mineral Resources (“DMR”), consisting of the Mining Work Program, Social and Labour Plan and associated Environmental Applications. The applications are supported by all of the JV partners including Impala Platinum Holdings Ltd. (“Implats”), Japan Oil, Gas and Metals National Corporation (“JOGMEC”) and Mnombo Wethu Consultants (Pty) Ltd. (“Mnombo”).

President and CEO of Platinum Group R. Michael Jones stated, “The filing of the Mining Right Application represents a significant milestone in the evolution of the Waterberg Project. First discovered in 2011, Waterberg has grown both in scale and stature to become a significant mineral asset and a rare, large scale, low cost primary palladium deposit. The project has the potential to positively impact South Africa’s economic development, creating high-value jobs and skills training opportunities for local residents. We look forward to ongoing interaction with all of our stakeholders, including government, local communities and our joint venture partners to help ensure the successful development and operation of the Waterberg Project.”

Waterberg represents a large scale resource of platinum group metals (“PGM”), including palladium, platinum and gold, with an attractive risk profile. Given its shallow nature and ability to support a fully mechanized operation, the Waterberg Project has the potential to be amongst the lowest cost producers in the PGM sector. A pre-feasibility study (“PFS”) was completed in 2016 and a definitive feasibility study (“DFS”) is in progress for completion in calendar Q1 2019. The DFS is considering two options including the 600ktpm complex outlined in the PFS and a phased approach commencing with a smaller, 250ktpm to 350ktpm alternative. Stantec Consulting International LLC and DRA Projects SA (Proprietary) Limited are the lead independent project engineers.

Platinum Group currently holds an effective 50.02% interest in the Waterberg Project. Implats, the world’s second largest platinum producer, owns a 15% interest. Mnombo, a black empowerment company, holds a 26% interest. The Company owns a 49.9% interest in Mnombo. JOGMEC holds a 21.95% interest in the Waterberg Project and is in the process of transferring a 9.755% interest to Japanese conglomerate Hanwa Co., Ltd. Hosken Consolidated Investments Limited, a South African black empowerment investment holding company listed on the JSE with a US$1.1 billion market capitalization, owns a 15% stake in Platinum Group. Implats is an active participant in the joint venture and holds an option to increase their stake to 50.01% following the completion of the DFS.

Implats has identified Waterberg as a potential low-cost alternative to deep conventional PGM mining, with an attractive metal balance for the future. Palladium has been gaining market interest based on continued demand in the auto sector, due to a growing trend towards gasoline engines and hybrids that use palladium dominant catalysts.

Current Platinum Group Element (“PGE”) Probable Mineral Reserves at the Waterberg Project (100%) are 12.3 million ounces, comprising 61% palladium, 30% platinum, 8% gold and 1% rhodium plus 191 million and 333 million pounds of copper and nickel respectively and will be updated as part of the DFS. (See the technical report dated October 19, 2016 and filed on SEDAR titled “Independent Technical Report on the Waterberg Project Including Mineral Resource Update and Pre-Feasibility Study”.) Much of the Waterberg Project area remains to be drilled and assessed. The Waterberg deposit remains open down dip and along strike.

Probable Mineral Reserve at 2.5 g/t 4E Cut-off– Contained Metal

Reasonable prospects of economic extraction were determined with the following assumptions: Metal prices used in the reserve estimate are as follows based on a 3-year trailing average (as at July 31/2016) in accordance with U.S. Securities and Exchange Commission ("SEC") guidance for the assessment of resources and reserves; US$1,212/oz Pt, US$710/oz Pd, US$1229/oz Au, US$984/oz Rh, US$6.10/lb Ni, US$2.56/lb Cu, US$/ZAR15. Smelter payability of 85% was estimated for 4E and 73% for Cu and 68% for Ni. The effective date is October 17, 2016. A 2.5 g/t Cut-off was used and checked against a pay-limit calculation. Independent Qualified Person for the Statement of Reserves is Mr. RL Goosen (WorleyParsons RSA (Pty) Ltd Trading as Advisian). The Mineral Reserves may be materially affected by changes in metals prices, exchange rates, labor costs, electricity supply issues or many other factors. See Risk Factors in Independent Technical Report 43-101 Effective Date: October 17, 2016 on www.sedar.com and the Company’s Annual Information Form. The Mineral Reserves are estimated under SAMREC with no material difference to the CIM 2014 definitions in this case.

The estimation of mineral reserves has taken into account environmental, permitting and legal, title, taxation, socio-economic, marketing and political factors. Based on the cut-off grade and a maximum depth cut-off of 1,250 metres the probable reserve will support an 18-year mine life.

An update to Mineral Resource based on completed in-fill drilling is in progress. This updated estimate with increased confidence will be the basis of the DFS mine design.

Estimates of mineralization and other technical information included herein have been prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). The definitions of proven and probable Mineral Reserves used in NI 43-101 differ from the definitions in SEC Industry Guide 7. Under SEC Industry Guide 7 standards, a “final” or “bankable” feasibility study is required to report Mineral Reserves, the three-year historical average price is used in any Mineral Reserve or cash flow analysis to designate Mineral Reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority. As a result, the reserves reported by the Company in accordance with NI 43-101 may not qualify as “Mineral Reserves” under SEC standards. In addition, the terms “Mineral Resource” and “measured Mineral Resource” are defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms under SEC Industry Guide 7 and normally are not permitted to be used in reports and registration statements filed with the SEC. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. Accordingly, descriptions of the Company’s mineral deposits in this press release may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements of United States federal securities laws and the rules and regulations thereunder.
