Recent Events

On September 16, 2024, the Company reported positive results from an Independent Definitive Feasibility Study Update (the "Waterberg DFS Update") for the Waterberg Project. The associated technical report entitled "Waterberg Definitive Feasibility Study Update, Bushveld Igneous Complex, Republic of South Africa", with an effective date of August 31, 2024, was filed on SEDAR+ on October 9, 2024. The Waterberg DFS Update was prepared by independent qualified persons in accordance with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") and Subpart 229.1300 and Item 601(b)(96) of the U.S. Securities and Exchange Commission's Regulation S-K (collectively, "S-K 1300"). The Waterberg DFS Update is an update to the Waterberg Project's original Independent Definitive Feasibility Study published in September 2019 (the "2019 DFS") for a safe, large-scale, shallow, decline-accessible, mechanised, PGM mine.

Key findings of the Waterberg DFS Update include:

• Increased Mineral Reserve Estimate: Proven and Probable mineral reserves increased by 20% to 23.41 million 4E oz (246.2 million tonnes at an average grade of 2.96 4E g/t, 0.08% copper ("Cu"), and 0.17% nickel ("Ni").

• Extended Life of Mine ("LOM"): LOM increased from 45 years to 54 years with annual steady state average production in concentrate of 353,208 4E oz and peak annual production of 432,950 4E oz.

• Robust Economics: After-tax Net Present Value at an 8% real discount rate of $569 million (South African Rand ("ZAR") 11.557 billion) and Internal Rate of Return of 14.2% using average long term consensus metal prices as of May 2024 ("Consensus Prices").

• One of the Lowest Cost PGM Mines in Southern Africa: On site LOM average cash cost (including base metal by-product credits and smelter discounts as a cost) of $658 per 4E oz, with an all-in sustaining cost of $761 per 4E oz.

• Strong Cash Flow Generation: LOM free after-tax cashflow of $6.50 billion (ZAR130.59 billion) at Consensus Prices.

• Reasonable Capital: Estimated total project capital of $946 million (ZAR18.862 billion), including 8.5% for contingencies, and peak capital estimated at $776 million (ZAR15.428 billion).

• Increased Confidence: The 32 hole infill drill program completed in 2023 increased the confidence level of resources in shallow mine blocks in the T-Zone and F-Central Zone, and refined the delineation of subcrop positions, improving the overall deposit model and the shallow portion of the mine plan.

• Increased Continuity: The 4E economic cut-off grade for feasibility modeling of the F-Central Zone and F-South Zone was reduced by one half a gram to 2.0 4E g/t, resulting in a slightly lower reserve grade, but significantly improving continuity in the ore body for mine scheduling purposes. F-Central reserve tonnage and 4E metal content increased by 88% and 63% respectively. Reserves for all other mineralized zones were estimated at a 2.5 4E g/t cut-off grade as in the 2019 DFS.

• Increased Mineral Resources: Measured and Indicated mineral resources increased by 9.5% to 33.76 million 4E oz at a 2.5 4E g/t (F-Central Zone and F-South Zone at 2.0 4E g/t) cut-off grade (345.03 million tonnes at an average grade of 3.04 4E g/t, 0.09% Cu and 0.18% Ni). Inferred mineral resources increased by 6.6% to 8.52 million 4E oz at a 2.5 4E g/t (F-Central Zone and F-South Zone at 2.0 4E g/t) cut-off grade (89.70 million tonnes at an average grade of 2.96 4E g/t, 0.08% Cu, and 0.15% Ni).

• Increased Tonnage Per Vertical Metre: Ore tonnes per vertical metre of development in the F-Central Zone also increased by approximately 88%, improving the steady state ore to waste ratio by 31%, from 11.3 in the 2019 DFS to 14.8 in the Waterberg DFS Update. LOM ore to waste ratio improved by 44%, from 7.8 in the 2019 DFS to 11.3 in the Waterberg DFS Update. The result is improved capital efficiency, reduced development metres per tonne of ore, and lower operating costs.

• Reduced Capital Expenditure: The 88% increase in F-Central reserve tonnage and the improved continuity of the reserve presented the opportunity to increase F-Central production to 400,000 tonnes per month ("tpm") and thereby reduce and delay the capital cost of developing the South Complex T-Zone infrastructure, saving an estimated $200 million in up-front capital.

• Simplified Mine Management: Deferral of South Complex mining will simplify the mine plan, logistics, training requirements, equipment fleet and mining method.

• Simplified Mine Establishment: Sublevel spacing for the upper mining block (100 metres) in the F-Central Zone reduced to 20 metres from the 2019 DFS combination of 20 metres and 40 metres to allow mine crews to safely complete mine establishment and gain work experience before transitioning to 40 metre sublevel spacing.

• Reduced Water Consumption: The Waterberg DFS Update models dry stack tailings technology, including a dewatering plant and dry tailings handling system, reducing estimated steady state make-up water requirements by 36% to approximately 2.85 megalitres per day and reducing the tailings impoundment surface footprint by approximately 46.0% to 155 hectares.

• Reduced Risk: Design and scheduling improvements as described above materially reduce execution risk during mine development, construction, ramp-up and operations.

• Flexibility: Any time after peak capital a twin heading into the T-Zone can be developed underground from the Central Complex infrastructure to allow the mining of up to 100,000 tpm of T-Zone, with a concurrent reduction from the F-Central Zone down to 300,000 tpm.

On April 3, 2024, the directors and shareholders of Waterberg JV Co. unanimously approved a $1.35 million stage four budget (the "Stage Four Budget") to allow the continuation of work programs underway while finalizing the Waterberg DFS Update. The Stage Four Budget, covering the period from March 2024 to approximately August 2024, was a subcomponent of a $21.0 million pre-construction work program (the "Work Program") approved for the Waterberg Project by the directors and shareholders of Waterberg JV Co. on October 18, 2022. With regard to the Stage Four Budget, Implats advised that its 2023 group wide restriction on capital expenditures remained in effect and they could not fund their share of current cash calls. In the fourth fiscal quarter of 2024, Implats' interest was diluted by 0.087% to approximately 14.864%. Platinum Group has funded Implats shortfall and the Company's direct interest in Waterberg JV Co. has increased concurrently with Implats dilution. Implats stated they would consider the funding of subsequent cash calls as future circumstances allow.

On December 20, 2023, the Company announced a Cooperation Agreement (the "Cooperation Agreement") with Ajlan & Bros Mining and Metals Co. ("Ajlan") to study the establishment of a stand-alone PGM smelter ("PGM Smelter") and base metal refinery ("BMR") in Saudi Arabia. Ajlan is a subsidiary of Ajlan & Bros Holdings, one of the largest private sector diversified conglomerates in the Middle East. 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 subsequent to August 31, 2024 by a globally recognized consulting group specializing in PGEs 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 PGE smelting and refining complex in Saudi Arabia. Other sources of mined PGE concentrate from Southern Africa could be considered over the longer term. Sources beyond South Africa are considered to be too early stage, too low in PGE content and too far away to be transported economically.

Ajlan and the Company are now considering the commissioning of the Smelter DFS. A key requirement would be to secure a long-term permit for the export of unrefined precious metals in concentrate from South Africa. 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. The Smelter DFS will assume the export of PGM concentrate from the Waterberg Project in South Africa to a port facility in Saudi Arabia and will encompass options related to infrastructure, location, technical specifications, capital, and operating costs. All expenses related to the Smelter DFS, expected to cost approximately US $4.0 million, are 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.

On December 11, 2023, the directors, and shareholders of Waterberg JV Co. unanimously approved a stage three budget of $1.65 million (the "Stage Three Budget") for continued work on the Waterberg Project covering the period from September 2023 to approximately February 2024. In conjunction with its approval, Implats advised that due to a restriction on capital expenditure across their portfolio, it could not fund its 15% share of the Stage Three Budget. As a result, Implats' interest in Waterberg JV Co. was diluted to approximately 14.951% during the third fiscal quarter of 2024. Platinum Group elected to fund Implats' funding shortfall and the Company's direct interest in Waterberg JV Co. increased concurrently with Implats' dilution.

On September 18, 2023, the Company reported the closing of a non-brokered private placement of common shares at a price of $1.18 per common share. An aggregate of 2,118,645 common shares were subscribed for and issued to existing major beneficial shareholder, Hosken Consolidated Investments Limited ("HCI"), through its subsidiary Deepkloof Limited, resulting in gross proceeds to the Company of approximately $2.5 million (the "Private Placement"). Closing of the Private Placement allowed HCI to return to more than a 26% interest in the Company.

Results For The Year Ended August 31, 2024

During the fiscal year August 31, 2024, the Company incurred a net loss of $4.58 million (August 31, 2023 – net loss of $5.66 million). General and administrative expenses during the period were lower at $3.42 million (August 31, 2023 - $3.89 million). Share based compensation was $1.36 million (August 31, 2023 - $1.98 million). The foreign exchange gain recognized in the current period was $4 thousand (August 31, 2023 - $0.25 million) due primarily to the U.S. Dollar increasing in value relative to the Canadian Dollar during the period.

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.

On October 18, 2022, Waterberg JV Co. approved in principle the Work Program, including proposed work on 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 the Waterberg DFS Update, including updated mineral resource and mineral reserve estimates, was also approved and has been completed.

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, 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.
