The project cash flow is scheduled annually and uses an exchange rate of 1.37 CAD to USD. Taxes were evaluated for federal and provincial corporate tax rates, as well as the Ontario Mining tax rates, subject to appropriate deductions for CEE, CDE, and depreciation allowances. Strategic Intent The Thunder Bay North project contains several critical minerals and therefore is ideally positioned to meet the priority goals of both the Federal and Provincial governments including advancing meaningful economic reconciliation with several Indigenous communities. The toll milling scenario contemplated in the Thunder Bay North PEA looks to take advantage of the significant processing capability in the region, specifically the Lac-des-Iles (LDI) Mine and Mill situated 65 km north of the Thunder Bay North project. The recent announcement from Impala Canada about the pending closure of the LDI mine presents a potential new opportunity. Clean Air Metals has a significant interest in working through unexplored options to utilize infrastructure at LDI, up to and including the possible acquisition of the assets and continued operation LDI with supplementary higher-grade feed from Thunder Bay North. There can be no certainty that any business arrangement with Impala Canada can be reached for the processing of ores from the Thunder Bay North Project. Path Forward for the Project Based on the strong initial economics and the current dynamic metals market, the Board of Clean Air Metals has given management approval to fast-track the project towards a final production decision. The key steps to reaching this milestone are as follows: Advancing appropriate NI 43-101 studies, engineering, environmental and permitting activities Continued consultation with local Indigenous communities Exploring all available processing opportunities Raising capital to fund the above work Begin assembling the construction financing plan, including support from the federal and provincial governments as well as the private sector Clean Air Metals Chair Jim Gallagher, P.Eng. stated: "The Board is quite pleased with the results of the study. The project features high-grade material very close to the surface with minimal infrastructure requirements, given its proximity to Thunder Bay. This results in a low-risk, quick-payback project. Recent drill results demonstrate the continuation of the mineral zones at depth, suggesting the potential for a significantly longer mine life. Given the very strong government support for critical mineral projects and the recent improvement in metal prices, there has never been a better time to move this project forward.” Capital and Operating Costs Summary The initial project capital cost is estimated at $89.5M, including a 25% contingency allowance for all capital items. The duration of the construction phase of the project is estimated at 24 months. The capital cost estimates are detailed in Table 2. Operating costs average $100.40 per tonne, driven by maximizing stope size and efficient operating development designs for near-surface, underground bulk mining. The operating cost summary is shown in Table 3.

The fundamentals for platinum, in particular, have been steadily improving, with increased deficits expected to continue for the next 5-10 years. Key market drivers that are fueling this price recovery include: Despite recent improvements, spot prices for PGEs continue below the marginal cost of supply for many primary PGE operations worldwide and thus are operating at a loss. This is resulting in production curtailments worldwide A significant volume of the world supply of PGEs originates in Russia and South Africa, which have aging infrastructure that is prone to disruptions, and have been generally heavily undercapitalized during this recent downturn Supply deficits have existed for 10 of the last 11 years Future growth in demand for PGEs will be driven in part by slowing battery electric vehicle growth, that is taken up by hybrid and plug-in hybrids that have significant PGE loadings. This is further supported by recent US policy changes regarding EVs Recycling has not picked up and is plagued by a lack of interest and investment Platinum is increasingly seen as a lower-cost store of value in the face of rising gold prices Following nearly four years of a declining outlook for PGEs, the Company believes that the strong results and timing of this study, in conjunction with recent exploration success in the Escape down-plunge, provide a solid platform for the Company to move forward. Table 7 shows the price deck for the study in comparison to the spot price on October 7th, 2025. Table 8 illustrates the potential impact on project metrics resulting from the increased interest in the platinum and palladium markets and associated changes in spot prices.

The information reported in the PEA for the Project is preliminary in nature. It includes Inferred Mineral Resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as Mineral Reserves. Inferred Mineral Resources are based on limited geological evidence and sampling. The tonnage and grade of Inferred Mineral Resources are subject to significant uncertainty regarding their existence and whether they can be mined economically. There is no certainty that the results for the PEA for the Project will be realized. Updated Mineral Resource The Updated Mineral Resource Estimate was prepared by SLR Consulting Ltd. ("SLR") and is based on an underground constrained resource model using a Net Smelter Return (NSR) cut-off value of US$46/tonne and consensus metal pricing. The Current Deposit contains an Indicated Mineral Resource of 8.8 million tonnes grading 2.7 g/t 2PGE ("Pt + Pd"), 0.32% copper and 0.22% nickel and an Inferred Mineral Resource of 1.7 million tonnes grading 1.7 g/tonne 2PGE, 0.32% copper, 0.21% nickel. The Escape Deposit contains an Indicated Mineral Resource of 6.0 million tonnes grading 2.6 g/t 2PGE, 0.52% copper, 0.28% nickel and an Inferred Mineral Resource of 0.8 million tonnes grading 1.4 g/tonne 2PGE, 0.27% copper, 0.17% nickel. Summaries of resource grades and contained metals are presented in Tables 9 and 10 below.

Wireframes for the ultramafic chonolith were generated based on logged lithologies and chromium assays. Higher grade mineralization wireframes were generated at a 1.0 g/t Pt + Pd cut-off grade with lower grades included to maintain continuity. Assays were composited to 2 m lengths and were used for block estimation on an uncapped basis, except for silver for which assays have been capped at 39 g/t before compositing for the Escape Deposit only. Pt, Pd, Au, Ag, Cu, Ni and density were interpolated using Ordinary Kriging (OK) into blocks measuring 5.0 m by 5.0 m by 2.5 m. Inverse Distance Squared (ID2) and nearest neighbour estimates were run for validation purposes. Blocks were classified following CIM Definitions (2014) as Indicated and Inferred using drill hole spacing based criterion. Indicated Mineral Resources were based on a nominal drill hole spacing of 50 m. Mineral Resources have been reported within underground reporting shapes based on an NSR cut-off value of US$46/tonne. A crown pillar exclusion of 20 m from the bottom of the overburden below lakes and the underground reporting shapes used during reporting ensure that the Mineral Resources meet the minimum requirements for Reasonable Prospects of Eventual Economic Extraction (RPEEE). NSR and Mineral Resources Cut-off Value NSR values have been estimated for an operating scenario that includes production of a split copper sulphide concentrate and a nickel-rich residual sulphide concentrate, each containing payable platinum and palladium, for both the Escape and Current deposits. Metal prices are based on consensus, long term forecasts from banks, financial institutions, and other sources. The metal prices and other input parameters used in development of a unit NSR value for each block is provided in Table 11. Table 11: – NSR Parameters in Resource Commodity Units Metal Prices (US$) Mill Recovery Refining Cost (US$) Palladium per oz $1,200 86% 15.00 Platinum per oz $1,400 81% 15.00 Silver per oz $38.00 69% 0.45 Gold per oz $2,800 84% 4.50 Copper per lb $5.00 94% 0.07 Nickel per lb $9.50 57% 0.03 Note: Transportation cost used in the resource was US $100/wet tonne,while Treatment costs used were US $70 for Cu concentrate and US $174 for Bulk Concentrate. For Mineral Resource reporting, underground constraining shapes were developed using Leapfrog Geo based on an NSR cut-off value of US$46/tonne. The cut-off parameters, based on current incremental operating cost estimates, are provided in Table 12. Table 12.

Production will be sampled on-site and sent for assays, with ROM production sent to an off-site facility for toll milling. Early revenue is generated by prioritizing near-surface production within the Lower Current and Bridge Zones, grading 3.2 g/t 2PGE + 0.4%Cu and 0.24% Ni for the first 5 years of production. All LOM production is contained within the indicated resource and does not contain any inferred resource. Operating costs average $100.40 per tonne mined with an NSR of $189 per tonne over the life, driven by maximizing stope size, efficient operating development design and optimizing use of backfill. Mine Operations The proposed Thunder Bay North operation involves underground mining of 2,500 tonnes per day of mill feed and a peak average of 1,000 tonnes per day of development waste. The Current Deposit is accessed via a portal from surface to the Current Deposit. Production ramp-up will take place over a period of 18 months with a nominal annual rate of 0.9 Mtonnes/year of toll-mill feed. The main ramp continues towards the Escape Deposit, where production starts in the Escape high-grade zone in production year 4. Long sections of the proposed Current Deposit and Escape Deposit are shown below in Figures 1 and 2. Figure 1: Current Deposit Long Section (Facing South-West) Figure 2: Escape Deposit Long Section (Facing South-West) The underground mining inventory was determined using Deswik Mineable Shape Optimizer (MSO) software tool. The MSO uses the geological block model to generate shapes (e.g., stopes) based on an initial mining cut-off of $96/tonne, and specifically targeting higher-margin mining zones within the larger resource. The mining underground inventory combines the three mining areas (Current, Bridge, and Beaver-Cloud) within the Current Deposit, and one mining area within the Escape Deposit. The underground stope inventory is constrained by a crown pillar, extending 20 m below the unconsolidated sediments below Current Lake. The Current and Escape deposits will be mined via conventional underground transverse long-hole open stoping using a combination of cemented rock fill (CRF) and unconsolidated rock fill (URF) where necessary. Early work using the stability graph method outlined the potential to have large, stable stope openings. Stopes are designed to be accessed and excavated via overcut and undercut development cross-cut drifts, which connect to the main declines. The main declines provide ventilation, haulage to surface, and mine access. Table 13 outlines key underground design parameters. Table 13: Underground Design Parameters Parameter Value Max Stope Dimensions Length 45m Height 20 to 40m Width 15 to 30m Development Dimensions Width 5m Height 5m Mining Parameters Mining Dilution 0.5m Mining Recovery 95% Mineralogy Platinum, palladium, and gold mineralization is very fine-grained; however, they are closely associated with all sulphide minerals, including pyrite, pyrrhotite and pentlandite, and recovery of the sulphides will therefore bring along the majority of the precious metal values. Copper is contained primarily as chalcopyrite, and approximately two-thirds of the nickel is in sulphide form, primarily as pentlandite. copper and nickel sulphide material liberation indicates a moderately fine grind is required for good recovery of the sulphides. The remaining nickel is mostly hosted by magnesium-silicate minerals, chiefly serpentine and olivine. Gangue silicates consist of serpentine, pyroxenes, olivine, and feldspar. Metallurgical Test Work Two rounds of metallurgical test work have been completed since 2021. The most recent test work developed and evaluated a sequential flowsheet and a bulk concentrate with a separation flowsheet, ultimately choosing the bulk flowsheet for improved PGM recovery. A total of 12 kinetic rougher tests were conducted to optimize the rougher circuit, followed by a total of 36 open-circuit tests to optimize the sequential and bulk separation flowsheets. A comparison of locked-cycle tests revealed that the idealized approach for recovery was to use a bulk concentrate, followed by separation into two concentrates. This program conducted a total of 91 tests including development, variability & locked cycle and other tests as well as extensive mineralogy & comminution measurements. The successful bulk with separation flowsheet includes grinding to a p80 of 65um in the presence of CuSO4, conditioning with CMC at a pH of 8.5 and bulk flotation using SIPX & 3477 with four stages of cleaning. The bulk cleaner concentrate is reground to a p80 of ~25um at a pH of 11. The regrind product is aerated before flotation in a Cu-Ni rougher with 3477 and 3 stages of cleaning. Results were verified with locked cycle tests and variability testing. Mineral Processing The PEA contemplates a regional toll-milling scenario for the Thunder Bay North Project, structured as a future ore sale agreement. No such agreement is currently in place. Run of mine feed would be accumulated into processing lots of an agreed-upon mass at site, sampled via a sampling tower, and transported to the local mining company’s concentrator for processing. Consolidated payability terms, which are outlined in Table 14, are based on a combination of projected mill recoveries, assumed smelter terms and minimum deductions, with toll milling fee, treatment charges and refining charges all payable by Clean Air Metals. The Company anticipates the need to undertake additional metallurgical testing, specifically on the toll milling facilities flowsheet, to validate our assumptions and identify optimization opportunities. Table 14: Estimated Payability Terms Within Toll Milling Metal Consolidated Payability Platinum 68% Palladium 77% Gold 40% Silver 21% Copper 84% Nickel 32% Key Onsite Project Infrastructure The project, as contemplated, focuses on minimizing on-site infrastructure. Where possible, site facilities are modular in nature and can be readily removed from the site with minimal cost or effort. Sample Tower and Ore Pad The site will have a lined ore pad and sample tower that will be used to sample ROM production from underground. The sample tower crushes ROM ore and splits it to recover appropriately sized samples for assaying. The pad will be designed to accommodate the dumping of underground production and the loading of ROM material for shipment off-site for processing. The ore pad will be reclaimed, and material will be sent underground at closure. Water Management Contact water, from the ore pad, as well as water pumped from underground, will be transferred to a 5,000 cubic metre pre-treatment pond. This pond is sized using information from the site's water balance study, and the design can handle climate-normal precipitation, including a 100-year 24-hour rainfall event. All water collected in this pond will be treated by a permitted mobile water treatment plant, with treated water discharged into Escape Lake. Power Power is assumed to be supplied via the recently constructed 230 kV E-W tie line, which runs to the south-east of the project site, through the project claims. The project will construct approximately 6 km of new power lines and associated electrical infrastructure to connect to this line. Access Road Access to the mine site can be achieved in cooperation with a major forestry company through a combination of upgrades to existing logging roads and the construction of new roads, totalling 10.5 km, which connect to paved Provincial Highway 527 to the West.
