Recent Events

On February 11, 2022, the Company repaid the remaining $3.0 million principal balance and outstanding interest of a senior secured loan facility with Sprott Private Resource Lending II (Collector), LP and the other lenders party thereto (the "2019 Sprott Facility"). After this repayment, the Company became debt free and the pledge of its South African assets as security was fully released.

On February 11, 2022, the Company completed a non-brokered private placement of 3,539,823 common shares at a price of $1.695 per common share to existing major beneficial shareholder, Hosken Consolidated Investments Limited ("HCI"), resulting in proceeds to the Company of $6.0 million (the "Private Placement"). Pricing of the Private Placement was set to be consistent with the equity consideration paid by the Company to purchase and cancel its outstanding $19.99 million 6 7/8% Convertible Senior Subordinated Notes ("Convertible Notes") as described below. The Private Placement allowed HCI to return to a near 26% interest in the Company, as it held prior to the purchase and cancellation of the Convertible Notes.

On February 11, 2022, the Company reported the privately negotiated purchase and cancellation of the Company's Convertible Notes maturing on July 1, 2022. The Company issued to the holders, on a private placement basis, an aggregate of 11,793,509 Common Shares of the Company at a price of $1.695 per share in consideration for the $19.99 million principal outstanding balance of the Convertible Notes. The Company settled accrued and unpaid interest on the Convertible Notes in cash.

On October 14, 2021, the Company reported completion of a geotechnical drilling campaign at the Waterberg Project consisting 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 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 a mining right at the Minerals and Petroleum Titles Registration Office (the "Waterberg Mining Right"). 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.

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 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 February 28, 2022, the Company had sold 7,960,324 common shares at an average price of $3.11 per share pursuant to the 2021 ATM for net proceeds of $24 million, after share issuance costs of $0.8 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 registered at the Mineral and Petroleum Titles Registration Office on July 6, 2021.

Results For The Six Months Ended February 28, 2022

During the six months ended February 28, 2022, the Company incurred a net loss of $6.0 million (February 28, 2021 - $6.6 million). In the current period, general and administrative expenses were $2.4 million (February 28, 2021 - $1.9 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. In the current period, interest expense of $1.6 million was recognized (February 28, 2021 - $2.5 million) with the reduction due to reduced overall debt outstanding during the current period. The currency translation adjustment recognized in the period was a loss of $2.4 million (February 28, 2021 - $3.3 million gain) with the variance due to the Rand decreasing in value relative to the U.S. Dollar during the current period.

At February 28, 2022, finance income consisting of interest earned and property rental fees in the period amounted to $51 thousand (February 28, 2021 - $48 thousand). Loss per share for the period amounted to $0.07, as compared to a loss of $0.09 per share for the six months ended February 28, 2021.

During the six months ended February 28, 2022, $9.4 million of principal was repaid against the 2019 Sprott Facility, eliminating the principal balance due. During the period the Company also fully settled the Convertible Notes.

Amounts receivable (including 2021 ATM proceeds receivable) at February 28, 2022, totalled $0.33 million (August 31, 2021 - $0.48 million) while accounts payable and accrued liabilities amounted to $0.9 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, accrued professional fees and regular trade payables.

Total expenditures on the Waterberg Project, before partner reimbursements, for the six-month period were approximately $1.9 million (February 28, 2021 - $0.9 million).

At February 28, 2022, $43 million in accumulated net costs had been capitalized to the Waterberg Project (February 28, 2021 - $40 million). Total expenditures on the property since inception from all investor sources to February 28, 2022, are approximately $80 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 project financing and a construction decision can be undertaken, arrangements will be required for project concentrate offtake or processing.

A Waterberg JV Co. budget in the amount of R40 million (approximately $2.7 million) for the fiscal period ending August 31, 2022, was approved by the partners to the joint venture on March 9, 2022. The Company is working to advance project permitting, engineering, infrastructure servitudes, surface access and community relationships. The Company continues to work closely with regional and local communities and their leadership on mine development plans to achieve optimal outcomes and best value to all stakeholders.

The Company is considering commercial alternatives for mine development, financing and concentrate offtake. Studies to assess the economic feasibility of constructing a dedicated Waterberg matte furnace to process Waterberg concentrate as an alternative to a traditional concentrate offtake arrangement are underway. The NI 43-101 definitive feasibility study technical report for the Waterberg Project entitled "Independent Technical Report, Waterberg Project Definitive Feasibility Study and Mineral Resource Update, Bushveld Complex, South Africa" dated October 4, 2019, stated that "Additional smelting capacity may need to be constructed in the industry to be able to treat the flotation concentrate from Waterberg and the other potential Platreef miners." Discussions with potential participating partners in a possible matte furnace facility are in process. Parallel discussions are also underway with South African smelter operators considering concentrate offtake arrangements for the project.

Implats currently holds a right of first refusal to match concentrate offtake terms offered to Waterberg JV Co. by bona fide third parties (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. involving one or more shareholders must be entered into on a bona fide arms-length basis and for fair value. Under the terms of the Waterberg JV Co. shareholders agreement, Hanwa holds the exclusive right to purchase or direct the sale of all or part of the Waterberg Project concentrate or metal contained therein.

The market for PGMs has steadily improved over the last several years resulting in higher 4E metal basket prices. Supply chain disruptions resulting from the global pandemic and exacerbated by the recent conflict in Ukraine continue to negatively impact global auto production. Notwithstanding weak auto demand, PGM prices have been supported by geopolitical tensions and the threat of Russian PGM exports being cut, representing a significant supply risk. Resolution of the conflict could remove some price support. Visibility on the resolution of supply chain issues is difficult to predict but PGM prices could strengthen in the medium term based on pent up auto demand once auto production normalizes. Major South African PGM producers are entering wage negotiations and additional supply risk could materialize should strike action occur. The projected market penetration of battery electric vehicles in the future could 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 represents a new opportunity in the high-profile lithium battery research and innovation field. The investment in Lion by the Company and Anglo creates a potential vertical integration with a broader industrial market development strategy to bring new technologies using palladium and platinum to market. Lion has concluded a sponsored research agreement with FIU. 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.
