Implats will also have a right of first refusal to smelt and refine Waterberg Project concentrate.

Recent Events

On July 15, 2019 Anglo American Platinum Ltd. ("Anglo Platinum") and the Company launched a new venture through Lion Battery Technologies Inc. ("Lion Battery"), to accelerate the development of next-generation battery technology using platinum and palladium. The possibility of creating additional demand for platinum and palladium in the battery technology space is an exciting development and of strategic importance to both parties.

Lion Battery has entered into an agreement with Florida International University to further advance a research programme that uses platinum and palladium to unlock the potential of Lithium Air and Lithium Sulfur battery chemistries to increase their discharge capacities and cyclability.

Under the agreement with Florida International University, Lion Battery will have exclusive rights to all intellectual property developed and will lead all commercialisation efforts. Lion is also currently reviewing several additional and complementary opportunities focused on developing next-generation battery technology using platinum and palladium. Lion Battery will be jointly funded and is to be a 52% owned subsidiary of Platinum Group with the remaining 48% owned by Anglo Platinum.

On June 28, 2019 the Company closed a non-brokered private placement with Hosken Consolidated Investments Limited ("HCI"), an existing major shareholder of the Company, for gross proceeds of US$1.3 million (the "Private Placement"). In connection with the Private Placement, the Company issued an aggregate of 1,111,111 common shares to Deepkloof Limited, a subsidiary of HCI, at a price of US$1.17 per common share. On a non-diluted basis and after giving effect to the Private Placement, HCI's ownership percentage increased from 20.05% to 22.60% of the Company's issued and outstanding common shares. The Company did not pay any finder's fees in connection with the Private Placement.

On June 20, 2019 HCI exercised certain common share purchase warrants to purchase 80,000 common shares at $1.70 per common share. Following the warrants exercise, HCI beneficially held 6,782,389 common shares of Platinum Group, representing 20.05% of the Company's then issued and outstanding common shares.

At May 31, 2019 common share purchase warrants representing 968,770 shares at a price of $1.70 each had been exercised by holders during the period. Proceeds to the Company totalled $1,646,909. The Company's two largest shareholders exercised approximately 91% of these warrants.

On March 7, 2019, the Company reported the transfer of a 9.755% interest in Waterberg JV Co. to Hanwa Co. Ltd. ("Hanwa") by JOGMEC. Prior to the transfer JOGMEC held a 21.95% interest in the Waterberg Project. Hanwa was the successful bidder in a public tender process for Japanese companies conducted by JOGMEC. Hanwa is a leading Japanese trading company supplying a broad spectrum of products, including steel, non-ferrous metals, metals and alloys, food, petroleum, chemicals, machinery, lumber and many other items, to a diverse range of global customers.

On January 11, 2019, the Company paid $8.0 million to Liberty Metals & Mining Holdings, LLC ("LMM") in partial settlement of a secured loan facility due to LMM. The amount paid represented net proceeds from the sale of 4.52 million common shares of JSE listed Royal Bafokeng Platinum Ltd. received by the Company in April 2018 upon completion of stage two of the sale of the Maseve Mine.

On November 16, 2018, the Company filed a National Instrument 43-101 technical report for an updated independent mineral resource estimate for the Waterberg Project. The report, entitled "Technical Report on the Mineral Resource Update for the Waterberg Project Located in the Bushveld Igneous Complex, South Africa" is dated October 22, 2018 (with the effective date of the mineral resources being September 27, 2018) (the "Waterberg Technical Report") and was prepared by Charles J Muller, B. Sc. (Hons) (Geology), Pr. Sci. Nat., of CJM Consulting (Pty) Ltd. A copy of the Waterberg Technical Report can be found at www.sedar.com, at www.sec.gov and on the Company's website.

On October 25, 2018, the Company published an updated independent mineral resource estimate for the Waterberg Project on a 100% basis, with 6.26 million ounces of platinum, palladium, rhodium and gold (together known as "4E") recognized in the higher confidence Measured category (57.2 million tonnes at 3.40 g/t 4E), 20.078 million 4E ounces recognized in the Indicated category (185.3 million tonnes at 3.37 g/t 4E), and a total of 26.34 million 4E ounces in the combined Measured and Indicated categories (242.5 million tonnes at 3.38 g/t 4E comprised of 63.04% palladium, 29.16% platinum, 6.37% gold and 1.43% rhodium).. The updated resource assessment forms the basis for mine design, scheduling and capital cost estimation as part of the DFS. The Waterberg deposit is dominated by palladium and also contains copper and nickel. Inferred mineral resources are estimated at 7.0 million 4E ounces (66.67 million tonnes at 3.26 g/t 4E). The T zone Measured and Indicated mineral resources increased in grade from 3.88 g/t 4E in 2016 to 4.51 g/t 4E in 2018. All of the preceding was estimated at a 2.5 g/t 4E cut-off grade, which is the preferred scenario for the project. Please refer to the Waterberg Technical Report for additional information regarding the updated mineral resource estimate.

On October 10, 2018, the Company announced that a recent Mining Right Application for the Waterberg Project had been accepted by South Africa's Department of Mineral Resources. The application is supported by the Company and all of the Waterberg Project partners including Implats, JOGMEC and Mnombo Wethu Consultants (Pty) Ltd. The process of consultation under the Mineral and Petroleum Resources Development Act, 2002 and current Environmental Assessment regulations has commenced. Many public meetings have already been completed. Significant feedback from the meetings has been considered in the DFS designs. Local training and employment are key components of the project to maximize the value of the project for all stakeholders.

Results For The Nine Months Ended May 31, 2019

During the nine months ended May 31, 2019 the Company incurred a net loss of $13.1 million (May 31, 2018 - net loss of $37.6 million). The lower loss in the current period is predominantly due to the Maseve Mine closure in the fourth quarter of fiscal 2017, resulting in care and maintenance costs of $14.2 million being recognized in the first nine months of fiscal 2018.

General and administrative expenses in aggregate during the nine-month period were $3.8 million (May 31, 2018 - $4.6 million). Specific items include interest expense of $7.3 million in the current period ($14.9 million May 31, 2018), with the decrease due to less debt outstanding the current period. A foreign exchange loss of $2.1 million was recognized in the current period (May 31, 2018 $3.9 million loss) due to a decrease in the value of the Canadian Dollar. A loss of $0.8 million was recognized on the valuation of embedded derivatives whereas a gain of $2.7 million was recognized in the previous comparable period, due largely to the increase in market value of the Company's shares. The currency translation adjustment recognized in the period is a gain of $2.4 million (May 31, 2018 - $8.3 million gain) due largely to the Rand increasing in value relative to the U.S. Dollar.

At May 31, 2019, finance income consisting of interest earned and property rental fees in the period amounted to $0.3 million (May 31, 2018 - $0.5 million), while a gain on marketable securities of $0.6 million was recognized in the current period (May 31, 2018 - $0.7 million loss). Loss per share for the period amounted to $0.42 as compared to a loss of $2.24 per share for the nine months ended May 31, 2018.

Accounts receivable at May 31, 2019 totalled $0.4 million (August 31, 2018 - $0.9 million) while accounts payable and accrued liabilities amounted to $2.2 million (August 31, 2018 - $3.6 million). Accounts receivable were comprised of mainly of amounts receivable for value added taxes repayable to the Company in South Africa and amounts due from joint venture partners and related parties. Accounts payable at May 31, 2019 related mostly to ongoing work at the Waterberg Project with the decrease as compared to August 31, 2018 being primarily due to settlement of payables related to mine closure costs.

Total expenditures on the Waterberg Project, before partner reimbursements, for the nine-month period were approximately $6.4 million (May 31, 2018 - $5.7 million). At May 31, 2019, $35.9 million in accumulated net costs had been capitalized to the Waterberg Project. Total expenditures by all parties on the property since inception are approximately $67.9 million.

Outlook

The Company's key business objective is to advance the Waterberg Project to development. The Waterberg project is dominated by palladium at a time when palladium supply is estimated to be in deficit. Mines with palladium as their primary economic mineral are rare.

Waterberg JV Co. is advancing the Waterberg Project to completion of a DFS. The DFS is being managed by Platinum Group and a technical committee with comprehensive input at all levels from the Waterberg Project partners. Completion and delivery of the DFS to Waterberg JV Co. is expected in the third calendar quarter of 2019. A Mining Right Application and an Environmental Authorization have been filed in South Africa following stakeholder consultations and both applications are being advanced.

Local involvement and personnel training are a key part of the design for a modern, safe, responsible mine operating at world class standards. The DFS team is working with NORCAT, a Sudbury, Canada based global training specialist, to incorporate local skills development into the DFS.

Important detailed infrastructure planning has commenced for the Waterberg Project. Detailed hydrological work indicates there is sufficient ground water resources for the Project and at the same time there is enough water to improve water accessibility to local communities. A co-operation agreement between Waterberg JV Co. and the local Capricorn Municipality for the development of water resources is actively advancing these objectives.

The establishment of servitudes for power line routes and detailed planning and permitting for an Eskom electrical service to the project are also advancing well. Power line environmental and servitude work is being completed by TDxPower in coordination with Eskom. Community consultation regarding power line routes and completion of an environmental impact assessment is in process.

The Waterberg JV Co. team is working very well together with value-add contributions coming from all partners, including senior team members from Implats working with Platinum Group Metals as Manager of the DFS. The mine plan includes large scale, bulk efficient underground mining from decline access with the use of backfill. The use of backfill will allow higher extraction ratios that had been projected in a pre-feasibility study for the Project, which modelled an open stoping mine method. The use of backfill will also reduce the required tailings impoundment area, costs and footprint. Stantec Consulting International LLC, an experienced global, bulk underground mine designer is completing the estimate of mineral reserves and the mine schedule for the DFS. DRA Project SA (Proprietary) Limited is completing the metallurgical design and overall capital cost estimate. We look forward to the finalization of the DFS.

A peer review of the DFS, excluding geology, by engineering firm SRK Consulting, is planned to commence in mid-July 2019. A review of the Waterberg Project geology and a resource estimate filed on SEDAR in October 2018 were previously the subject of a peer review by engineering firm Amec Foster Wheeler.

Within 90 days of the completion and approval of the DFS by Waterberg JV Co., Implats may elect to increase its Waterberg Project stake to 50.01% by additional share purchases from JOGMEC for an amount of $34.8 million and a commitment to spend $130 million for development of the Waterberg Project.

The Company believes that its investment in Lion Battery, co-founded with Anglo Platinum, represents an exciting opportunity in the high-profile lithium battery research and innovation field. The Company believes that its investment in Lion Battery creates a potential vertical integration with a broader industrial market development strategy to bring new technologies to market which use platinum and palladium.

In the near term, the Company's liquidity will be constrained until financing has been obtained to repay and discharge remaining amounts of secured debt and for working capital purposes. The Company remains focussed on completing the Waterberg DFS. The Company is currently discussing opportunities with several finance groups regarding the settlement or refinancing of a secured loan facility due to LMM as well as the Company's working capital requirements. The Company will continue to work closely with its major shareholders and lenders. The Company continues to actively assess corporate and strategic alternatives with advisor BMO Capital Markets.

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 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 reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate 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 "reserves" under SEC Industry Guide 7. 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 historically have not been permitted to be used in reports and registration statements filed with the SEC pursuant to SEC Industry Guide 7. 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 SEC Industry Guide 7.
