Recent Events

On October 14, 2021, the Company reported completion of a geotechnical drilling campaign at the Waterberg Project. The campaign consisted of 46 boreholes drilled along the planned centerline of two sets of twin declines and box-cut positions. A total of 5,966 metres of drill core were recovered and a total of 2,696 metres of core were geotechnically logged from within the zone of interest. Downhole geophysical surveys were conducted. Core samples of all the major geotechnical units encountered were collected and subjected to laboratory testing. Geotechnical qualified persons monitoring the drill programme determined that in general, the rock mass encountered along both decline routes is competent and can support the planned excavations with no major problem areas expected.

On July 6, 2021, Waterberg JV Resources Proprietary Limited ("Waterberg JV Co.") completed the registration of the Waterberg Mining Right at the Minerals and Petroleum Titles Registration Office. The Waterberg Mining Right was notarially executed by the Department of Mineral Resources and Energy ("DMRE") on April 13, 2021 and remains active.

On June 15, 2021, the U.S. Patent and Trademark Office issued Patent No. US 11,038,160 B2 entitled "Battery Cathodes for Improved Stability" to FIU. The patent covers a preparation method using PGM catalysts in carbon materials for use as cathodes with increased emphasis on Lithium Sulphur Batteries. The patent broadens protection for Patent No. US 10,734,636 B2 issued to FIU on August 4, 2020, covering the composition of carbon cathodes containing PGMs. Under a sponsored research agreement, the Company's subsidiary Lion has exclusive rights to such battery technology being developed by FIU, including patents granted. Lion was jointly formed in 2019 by Platinum Group and Anglo to accelerate the development of next-generation battery technology using platinum and palladium.

On and following March 5, 2021, three notices of appeal were filed by individual appellants against the January 28, 2021 granting of the Waterberg Mining Right. Counsel acting for one group filed an application for an order in the High Court of South Africa to review and set aside the decision by the Minister of the Department of Forestry, Fisheries, and the Environment to refuse condonation for the late filing of that group's appeal against the grant of an Environmental Authorization for the Waterberg Mine in November 2020. Waterberg JV Co. filed formal rebuttals to each action. On July 30, 2021, a group located near planned surface infrastructure filed an urgent interdict application. Waterberg JV Co. promptly filed an answering affidavit denying urgency and arguing that the application is without merit. The applicants did not respond and were obliged to remove their application from the urgent court roll. Host community Ketting has applied to join as an interested party to the application and another host community submitted a confirmatory affidavit, both communities being in support of the Waterberg Mine. Dates for court hearings or the settlement of appeals are uncertain or may never occur.

On February 5, 2021, the Company entered into an Equity Distribution Agreement with BMO Capital Markets Corp. ("BMO") to sell its common shares from time to time for up to $50.0 million in aggregate sales proceeds in "at-the-market" transactions (the "2021 ATM"). As of November 30, 2021, the Company had sold 7,070,580 common shares at an average price of US$3.24 per share pursuant to the 2021 ATM for net proceeds of $21.6 million, after share issuance costs of $1.3 million. No offers or sales of common shares were made in Canada, to anyone known to be a resident of Canada or on or through the facilities of the Toronto Stock Exchange (the "TSX") or other trading markets in Canada.

On January 28, 2021, the DMRE granted Waterberg JV Co. the Waterberg Mining Right. The Waterberg Mining Right was notarially executed by the DMR on April 13, 2021 and was then registered at the Mineral and Petroleum Titles Registration Office on July 6, 2021.

Results For The Three Months Ended November 30, 2021

During the three months ended November 30, 2021, the Company incurred a net loss of $3.32 million (November 30, 2020 - $2.56 million). In the current period, general and administrative expenses were $1.3 million (November 30, 2020 - $0.8 million) with the increase primarily due to legal fees for the Africa Wide trial, which took place during October, 2021. For more information about the Africa Wide trial, see Note 9 of the Financial Statements. Share based compensation was $0.7 million (November 30, 2020 - $0.4 million) with the increase due to a higher fair value of stock options vesting during the current period at a higher share price. Interest expense of $1.0 million (November 30, 2020 - $1.3 million) was lower due to the reduction in debt during the current period. The currency translation adjustment recognized in the period was a loss of $3.7 million (November 30, 2020 - $3.2 million gain) with the variance due to the Rand decreasing in value relative to the U.S. Dollar during the current period.

At November 30, 2021, finance income consisting of interest earned and property rental fees in the period amounted to $25 thousand (November 30, 2020 - $24 thousand). Loss per share for the period amounted to $0.04, matching a loss of $0.04 per share for the three months ended November 30, 2020.

During the three months ended November 30, 2021, $5.8 million of principal was repaid against the senior secured Sprott Facility, bringing the nominal principal balance due at November 30, 2021 down to $3.6 million. After period end, the Company made a further principal repayment of $0.6 million, bringing the nominal principal balance down to $3.0 million as of December 31, 2021.

Amounts receivable (including ATM Offering proceeds receivable) at November 30, 2021 totalled $0.69 million (August 31, 2021 - $0.48 million) while accounts payable and accrued liabilities amounted to $1.25 million (August 31, 2021 - $2.46 million). Amounts receivable were comprised mainly of value added taxes repayable to the Company in South Africa. Accounts payable consisted primarily of Waterberg engineering fees, geotechnical drilling costs, accrued professional fees and regular trade payables.

Total expenditures on the Waterberg Project, before partner reimbursements, for the three month period were approximately $1.3 million (November 30, 2020 - $0.54 million).

At November 30, 2021, $41.4 million in accumulated net costs had been capitalized to the Waterberg Project (November 30, 2020 - $38.4 million). Total expenditures on the property since inception from all investor sources to November 30, 2021 are approximately $79.4 million.

Outlook

The Company's key business objective is to advance the Waterberg Project to a development and construction decision. PTM is the operator of the Waterberg Project as directed by a technical committee comprised of representatives from joint venture partners Impala Platinum Holdings Ltd. ("Implats"), Mnombo Wethu Consultants (Pty) Ltd. ("Mnombo"), Japan Oil, Gas and Metals National Corporation ("JOGMEC") and Hanwa Co. Ltd. ("Hanwa"). Before a construction decision can be undertaken, arrangements will be required for project concentrate offtake or processing. A Waterberg JV Co. budget for fiscal 2022 is in development and discussion with the partners to the joint venture. The Company continues to work closely with regional and local communities and their leadership on how the mine can be developed to provide optimal outcomes and best value to all stakeholders. The Company is working to advance project permitting, engineering, infrastructure servitudes, surface access and community relationships.

The Company is assessing commercial alternatives for mine development, financing and concentrate offtake. Studies to assess the economic feasibility of establishing a dedicated Waterberg matte furnace to process Waterberg concentrate as an alternative to a traditional concentrate offtake arrangement are underway. Implats currently holds a right of first refusal to match concentrate offtake terms offered to Waterberg JV Co. by a bona fide third party (the "Offtake ROFR"). Processing of Waterberg concentrate through a matte furnace owned by Waterberg JV Co. or by one or more of the Waterberg JV partners would not be subject to the Offtake ROFR as such an entity would not be a "bona fide third party." Any transaction between Waterberg JV Co. and any one or more shareholders must be entered into on a bona fide arms-length basis and for fair value. Under the terms of the shareholders agreement governing Waterberg JV Co., Hanwa holds the exclusive right to purchase or direct the sale of all or part of the Waterberg Project concentrate or metal contained therein. Hanwa may therefore direct the processing and marketing of Waterberg Project concentrate or contained metal at market prices, once again without being subject to the Offtake ROFR.

The market for PGEs, palladium and rhodium in particular, has improved since 2019, resulting in generally higher 4E metal basket prices in 2020 and 2021. In 2021, the impact of a global shortage of semi-conductors resulted in reduced global automotive production. The concurrent reduction in demand for PGEs led to prices for each of the PGEs to fall from their mid-year highs. Effects of the semi-conductor shortage are expected to ease in 2022 or into 2023. Industry analysts estimate a return to strength in the market for platinum, palladium and rhodium based on projections for a recovery in car sales and the longer term potential for the emergence of hydrogen-based technologies utilizing PGEs. The projected market penetration of battery electric vehicles in the future is expected to soften the market for palladium in the longer term as demand for internal combustion engines with catalytic converters is potentially reduced. Other metals to be produced at Waterberg, being platinum, rhodium, gold, copper and nickel, are expected to see strong demand and prices in the longer term.

The Company's battery technology initiative through Lion with Anglo represents a new opportunity in the high-profile lithium battery research and innovation field. The investment in Lion creates a potential vertical integration with a broader industrial market development strategy to bring new technologies to market which use palladium and platinum. Research and development efforts by FIU on behalf of Lion continue. The U.S. Patent and Trademark Office has issued three patents to FIU to date. Several more patent applications are in process. Technical results from Lion's research may have application to most lithium-ion battery chemistries and the scope of Lion's research work is being expanded.
