Results For The Year Ended August 31, 2023

During fiscal 2023, the Company continued its efforts to lower costs. During the year ended August 31, 2023, the Company incurred a net loss of $5.66 million (August 31, 2022 - net loss of $8.24 million). The current year loss was lower primarily due to interest expense being reduced to $nil in the current fiscal year, versus $1.65 million in fiscal 2022. All the Company's remaining debt was paid off during fiscal 2022. General and administrative expenses during the year were lower at $3.89 million (August 31, 2022 - $4.34 million). Share based compensation was also lower at $1.98 million (August 31, 2022 - $2.16 million). The foreign exchange gain recognized in the current year was $0.25 million (August 31, 2022 - $0.33 million gain) due to the to the U.S. Dollar increasing in value relative to the Canadian Dollar during the period.

At August 31, 2023, finance income consisting of interest earned and property rental fees in the year amounted to $0.58 million (August 31, 2022 - $0.18 million). Basic and diluted loss per share for the year amounted to $0.06 as compared to a loss of $0.09 per share for fiscal 2022.

Accounts receivable at August 31, 2023 totalled $0.22 million (August 31, 2022 - $0.38 million) while accounts payable and other liabilities amounted to $1.37 million (August 31, 2022 - $1.12 million). Accounts receivable was comprised primarily of value added taxes repayable to the Company in South Africa. Accounts payable consisted primarily of payables related to project engineering and maintenance costs on the Waterberg Project.

On July 27, 2022, the Company entered into an Equity Distribution Agreement with BMO Nesbitt Burns Inc. and BMO Capital Markets for a new at-the-market equity program (the "2022 ATM") to distribute up to $50.0 million (or the equivalent in Canadian dollars) of Common Shares. No common shares were sold pursuant to the 2022 ATM prior to August 31, 2022. As of August 31, 2023, the Company had issued 1,089,503 Common Shares, through BMO Capital Markets on the NYSE American pursuant to the 2022 ATM, at an average price of $1.81, for gross proceeds of $1.98 million. Directly attributable expenses and legal fees to maintain the 2022 ATM in good standing, and for commissions on equity sales, totaled $0.45 million during fiscal 2023.

Total expenditures on the Waterberg Project, before partner reimbursements, for the year were approximately $4.44 million (August 31, 2022 - $3.36 million). At year end, $41.61 million in accumulated net costs were capitalized to the Waterberg Project (August 31, 2022 - $40.37 million). Total expenditures on the property since inception to August 31, 2023 are approximately $85.4 million.

Outlook

The Company's primary 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 Proprietary Limited ("Mnombo"), and HJM. Before project financing and a construction decision can be undertaken, arrangements will be required for project concentrate offtake or processing.

On October 18, 2022, Waterberg JV Co. approved in principle the pre-construction Work Program (as described above) for approximately $21.0 million over a 23-month period ending August 31, 2024. The Work Program, to be funded pro rata by the joint venture partners, includes work on project infrastructure including initial road access, water supply, essential site facilities, a first phase accommodation lodge, a site construction power supply from state utility Eskom and advancement of the Waterberg Social & Labour Plan. Work to prepare an update to the 2019 Waterberg Definitive Feasibility Study with updated mineral resource and mineral reserve estimates was also approved and is currently in process, and will include a review of cut-off grades, mining methods, infrastructure plans, scheduling, concentrate offtake, dry stack tailings, costing and other potential revisions to the project's financial model (the "DFS Update").

From the Work Program, an Initial Budget of approximately $2.5 million was approved, funded and completed by March 31, 2023, including thirty-two infill boreholes, several geotechnical boreholes, and one exploration borehole. A Stage Two Budget for $3.6 million in work was approved for expenditure on March 24, 2023 and substantially completed in October 2023. The Stage Two Budget included DFS Update engineering, pre-construction engineering, electrical power supply engineering and the permitting and licensing of construction aggregate borrow pits identified near the Waterberg mine site. A Stage Three Budget in the amount of $1.62 million is currently in process of approval by consent resolutions of the board of directors, and shareholders of Waterberg JV Co. The Stage Three Budget includes completion of the DFS Update and other engineering and the permitting work already underway. A final Stage Four Budget in accordance with the Work Program is expected to be considered for approval in approximately February or March of 2024.

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.

Before project financing and a construction decision can be undertaken, arrangements will be required for project concentrate offtake or processing. In addition to seeking reasonable terms for Waterberg concentrate offtake from an existing smelter/refiner in South Africa, the Company must also consider alternatives. The Company is assessing the economic feasibility of constructing a matte furnace and base metal refinery in South Africa, either with or without investment partners, to process Waterberg concentrate. A matte furnace and base metal refinery as described above is envisioned as a separate business from Waterberg JV Co. that could provide fair market concentrate offtake terms to Waterberg JV Co. and possibly to other PGM miners.

The Company is also assessing the economic feasibility of constructing a matte furnace and base metal refinery outside of South Africa to process Waterberg concentrate. Working with a potential partner in a jurisdiction with less expensive power and water, the Company has completed a trade off study which indicates that savings on power and water substantially offset the cost of additional concentrate transportation. Before concentrate could be exported from South Africa, a formal government approval would be required. Further studies are underway.

As the world seeks to decarbonize and look for solutions to climate change, the adoption of battery electric vehicles is forecast to reduce the future demand for PGMs used in autocatalysis. The unique properties of PGMs as powerful catalysts are being applied to various technologies as possible solutions for more efficient energy generation and storage, which may create new demand for PGMs. The Company's battery technology initiative through Lion with partner Amplats represents one such 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. 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.
