Results For The Six Months Ended February 28, 2025

During the six months ended February 28, 2025, the Company incurred a net loss of $2.25 million (February 28, 2024 - net loss of $2.37 million). General and administrative expenses during the period were higher at $2.0 million (February 28, 2024 - $1.82 million) due to legal costs related to the Shelf Prospectus, the Registration Statement, the 2025 ATM, the completion of the Waterberg DFS Update, and a reimbursement of legal costs in the previous comparable period. Stock based compensation was lower at $0.45 million in the current period (February 28, 2024 - $0.59 million) due to the revaluation of outstanding deferred share units in the current period. The foreign exchange gain recognized in the current period was $0.15 million (February 28, 2024 - $0.03 million gain) due primarily to the U.S. Dollar increasing in value relative to the Canadian Dollar during the period.

At February 28, 2025, finance income consisting of interest earned in the six month period amounted to $0.10 million (February 28, 2024 - $0.25 million). Basic and diluted loss per share for the six months ended February 28, 2025, amounted to $0.02, which was also $0.02 per share for the comparable period ended February 28, 2024.

Accounts receivable at February 28, 2025, totalled $0.18 million (August 31, 2024 - $0.23 million) while accounts payable and other liabilities amounted to $0.69 million (August 31, 2024 - $0.91 million). Accounts receivable was comprised primarily of value added taxes repayable to the Company in South Africa. Accounts payable consisted primarily of professional fees payable in relation to the preparation and filing of the Shelf Prospectus, the Registration Statement and the 2025 ATM, as well as for project engineering and maintenance costs on the Waterberg Project.

Total expenditures on the Waterberg Project, before partner reimbursements, for the six months ended February 28, 2025, were approximately $1.0 million (February 28, 2024 - $1.63 million). At period end, $45.9 million in accumulated net costs were capitalized to the Waterberg Project. Total expenditures on the property since inception to February 28, 2025, are approximately $90.1 million.

Smelting and Refining Update

On December 20, 2023, the Company announced a Cooperation Agreement (the "Cooperation Agreement") with Ajlan to study the establishment of a stand-alone PGM Smelter and BMR in Saudi Arabia. The Cooperation Agreement encompasses three phases: a global PGM concentrate market study (the "Market Study"), a Definitive Feasibility Study for the construction and operation of the PGM Smelter and BMR in Saudi Arabia (the "Smelter DFS"), and an option to form an incorporated 50:50 joint venture following the completion of the Smelter DFS.

An initial trade-off study was completed in mid 2023 to first determine the viability of exporting PGM concentrate from South Africa to Saudi Arabia. The Market Study was completed in late 2024 by a globally recognized consulting group specializing in PGMs and associated base metal by-products. Based on the analysis, the combination of concentrate from the Waterberg Project and end of life auto catalysts and petrochemical catalysts, sourced from the Gulf Region, could justify the scale required to construct a long term PGM smelting and refining complex in Saudi Arabia. Other sources of mined PGM concentrate from Southern Africa could be considered over the longer term. Sources beyond Southern Africa are considered too early stage, too low in PGM content and too far away to be transported economically.

The Smelter DFS was to assume the export of PGM concentrate from the Waterberg Project in South Africa to a port facility in Saudi Arabia and was to encompass options related to infrastructure, location, technical specifications, capital, and operating costs. All expenses related to the Smelter DFS, expected to cost approximately $4.0 million, were to be split on a 50:50 basis between Platinum Group and Ajlan, including certain costs already incurred by Platinum Group in previous independent beneficiation studies.

A key requirement for the above proposal to establish a PGM Smelter and BMR in Saudi Arabia would be a long-term South African government approval for the export of unrefined precious metals in concentrate. Platinum Group has been working with the Government of South Africa to identify local beneficiation opportunities and to analyze the possible impact of exporting concentrate on the value chain. Through these discussions the government of South Africa has expressed their preference and support for beneficiation in South Africa. As a result, Ajlan and PTM are also now studying the possibility of establishing a matte furnace in South Africa capable of smelting Waterberg Project concentrate. Such a facility would ideally be located near the Waterberg Project with existing power, water and environmental authorizations. The converter matte produced would be shipped to Saudi Arabia for further processing through a BMR, at which time spent auto catalysts and other PGM bearing materials could be co-processed.

The Company and Ajlan are currently conducting a trade off study and developing a scope of work and cost estimate for the engineering studies required to assess the above scenario, should it be chosen as the primary plan. One noteworthy consideration would be the much lower volume of material to be shipped to Saudi Arabia. Rather than shipping up to 130,000 tonnes of concentrate a year, or approximately fourteen concentrate trucks a day, the volume of converter matte to be shipped would be reduced to approximately 8,000 tonnes a year, or approximately one truck a day.

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 Implats, Mnombo, and HJM.

Since October 18, 2022, Waterberg JV Co. has been advancing exploration and engineering work related to the Waterberg DFS Update, initial road access, water supply, infrastructure and 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. Engagement with local communities has been ongoing and together the parties have agreed upon the location of project facilities and infrastructure.

Before a construction decision can be undertaken, arrangements will be required for Waterberg Project concentrate offtake or processing. The Company and Waterberg JV Co. are assessing commercial alternatives for mine development financing and concentrate offtake. In addition to the Company's investigation of smelting and base metal refining options in Saudi Arabia (as described above), the Company is also in discussion with several South African smelter operators, including Implats, with a view to negotiating formal concentrate offtake arrangements for the Waterberg Project.

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.

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 and lithium-sulfur battery chemistries.

Although platinum and palladium are exempt, as they are considered critical minerals, the new global tariffs recently announced by the United States administration in Washington, DC, layered on top of previously announced tariffs on automobiles, steel, aluminum, etc., have raised uncertainty regarding markets in general and specifically to the production and sale of automobiles and light duty vehicles. A period of uncertainty is likely as investors and consumers consider the impact of these tariffs, and as the level of retaliation and market diversification by other nations becomes apparent.
