Infini Resources Limited (ASX:I88) (“Infini” or the “Company”) advanced its Canadian uranium exploration portfolio during the September quarter, progressing from integrated target definition to the commencement of its most substantial exploration program to date at Portland Creek. Completion of airborne radiometric surveying, extensive fieldwork and three- dimensional magnetic modelling sharpened the Company's exploration model and targeting, underpinning an expanded ~5,000 m Phase 3 diamond drilling program supported by ~1,000 m of trenching. At Reynolds Lake and Reitenbach Lake, completion of the maiden 16-hole, 3,314 drill metre program provided the first subsurface assessment of priority targets, intersecting reactivated graphitic structures and hydrothermal alteration that will inform the next stage of exploration. Quarterly Activities Report for the Period Ending 30 September 2026 ASX:I88 Summary of Exploration Activities Portland Creek Uranium Project (100% owned, Newfoundland Canada) The Portland Creek Uranium Project spans 328 km2 and lies within the Precambrian Long-Range Complex of the Humber Tectonic-Stratigraphic Zone. The geology consists of metaquartzite and a suite of paragneisses, intruded by leucocratic granite, which are believed to have been thrust westward over Paleozoic carbonate-dominant sediments. The project area covers large regional uranium anomalies, first identified in the 1970’s through a Newfoundland government lake-sediment sampling program. A uranium showing was recorded in the Newfoundland Mineral Deposit Index, reporting 2,180 ppm U3O8. Compilation of historic and recent exploration data has delineated a ~6 km zone of anomalous uranium and radon gas responses across lake sediments, soils and airborne radiometric datasets. This anomalism closely follows a prominent fault scarp, marking the edge of a granitic plateau interpreted as a deep-seated fault. Since staking the project in 2023, the Company has rapidly advanced the project through multiple exploration phases in an area that has been historically underexplored for uranium mineralisation. The Company has verified historical regional uranium anomalies and completed a soil sampling grid over the Falls Lake Prospect. This work defined a ~800 m x 100 m high-grade uranium surface anomaly, with a peak soil result of 74,997 ppm U3O8. This anomaly is located down-ice and west of a 1.5 km radiometric anomaly. Additionally, Infini has identified a southern 500 m-wide cluster of high-grade soil samples, which includes a peak of 1,500 ppm U3O8 and lies 1.5 km from drilling undertaken in the Phase 2 drill program. Project-Wide Airborne Geophysics Completed at Flagship Portland Creek Project Infini completed a high-resolution airborne radiometric survey at Portland Creek, strengthening the geophysical dataset across the surveyed portion of its expanded tenure package. The helicopter-borne survey comprised 737 line-kilometres over 200 m-spaced flight lines. Integration of this data with existing airborne magnetic and electromagnetic datasets, surface geochemistry and Phase 1 and Phase 2 drilling information has significantly improved definition of major faults, structural intersections, demagnetised zones and radiometric anomalies. The final electromagnetic dataset did not identify discrete bedrock conductors of significance within the survey area, consistent with the Company's interpretation of fracture-controlled uranium mineralisation within granite rather than mineralisation associated with conductive sulphides or graphitic metasediments. Collectively, this work advanced the Company’s understanding of the structural controls on uranium mineralisation across Portland Creek, providing a stronger geological framework for prioritising targets and guiding follow-up exploration. Completion of Portland Creek Field Program and Geological Observations A helicopter-supported mapping, prospecting and sampling program was completed during the Quarter, recording 465 geological observation stations across approximately 283 km of ground traverses. Continuous radiometric profiling collected more than 51,000 measurement points, providing extensive ground assessment of priority airborne anomalies and their geological setting. Ground spectrometer surveying recorded commonly elevated responses of 1,300-2,700 counts per second (cps), compared with typical host-rock background of 500-800 cps, and discrete peaks of 7,100 cps, 8,800 cps and 9,400 cps. The strongest responses were consistently associated with fractured and bleached granite, leucogranite veins and sericitic fault gouge, reinforcing the interpreted relationship between brittle structures, hydrothermal alteration and radiometric anomalism. Portable XRF screening returned indicative uranium readings of up to approximately 2,800 ppm U, averaged from multiple readings at the fault-gouge location. Cautionary Statement The Company has identified potential uranium mineralisation in the field by using hand held pXRF technology to analyse rock chip samples in real time. This allows for immediate on-site decisions to be made to adjust prospecting strategies. While pXRF readings provide a useful indication of mineral content and approximate grades, they are not a substitute for laboratory-derived assay grades and will not be used in any resource estimation. Portable pXRF results reported are considered semi-quantitative; as such, results from pXRF analysis are stated as indicative only, provide confirmation that mineralisation is present; however, they may not be representative of elemental concentration within the Quarterly Activities Report for the Period Ending 30 September 2026 ASX:I88 material sampled and are preliminary to subsequent confirmation (or otherwise) by geochemical laboratory analysis. Limitations of pXRF readings include: very small analysis window, possible inhomogeneous distribution of mineralisation, analytical penetration depth, possible effects from irregular rock surfaces. Results are not considered to be entirely representative of the rock samples, as the analyses were made of what were interpreted to be areas in outcrop with potential. Ground radiometric measurements are point measurements of in-situ radioactivity at the rock surface and are influenced by factors including the geometry and orientation of the measurement surface, rock surface condition, moisture, vegetation and weathering, and the depth of investigation of the instrument, which is limited to the near-surface. Individual peak readings may represent discrete, localised responses and should not be taken to imply that elevated radioactivity extends over a broader area, at depth, or with any continuity. The spectrometer is operated and calibrated in accordance with manufacturer specifications; however, no radiometric data reported in this announcement have been converted to equivalent uranium (eU) concentrations or otherwise quantified. Total-count spectrometer readings are used by the Company solely as an exploration targeting and prospecting guide, and all determinations of uranium content remain subject to laboratory assay. Advanced 3D Modelling Unlocks District-Scale Uranium Targets at Portland Creek Following completion of the 2026 airborne magnetic, electromagnetic and radiometric surveys, and integration of those datasets with the results of the 2026 field program, the Company has conducted the detailed reinterpretation of existing datasets to refine the exploration model and targeting ahead of the planned Phase 3 exploration program. Three-dimensional inversion modelling of the 2026 airborne magnetic data has advanced the Company's understanding of the Portland Creek uranium system. The modelling resolves, for the first time, the three-dimensional geometry of the boundary between preserved magnetic anomalies and extensive zones of magnetic destruction, and indicates that magnetic destruction is developed along and adjacent to the interpreted structural network rather than being randomly distributed through the granite. The Company interprets this as the mapped footprint of a large, structurally controlled hydrothermal system, and its scale and continuity at depth are considered a significant positive indicator of the potential size of the mineralising system at Portland Creek. The 2026 airborne radiometric survey has concurrently refined the distribution of surface uranium response across the project, with the strongest responses coinciding with the interpreted structural corridors. Together, these datasets have transformed a series of surface uranium occurrences into a coherent, district-scale target set with defined geometry at depth and provide the framework within which Phase 3 exploration activities have been designed. Targeting is directed at locations where several independent vectors coincide, specifically: • Intersections between the interpreted east-west and cross-cutting north-northwest to north-northeast structural sets, interpreted as sites of dilation and enhanced permeability. • The boundary between preserved magnetic anomalies and zones of magnetic destruction, interpreted as the interface across which mineralising fluids reacted with the host granite. • Uranium anomalism defined by rock sampling, ground radiometric traverses and airborne radiometric data. • Structural corridors where the interpreted fault architecture is most complex. Quarterly Activities Report for the Period Ending 30 September 2026 ASX:I88 Figure 1: Phase 3 exploration program at Portland Creek, approximately 5,000 m of diamond drilling supported by approximately 1,000 m of trenching, targeting the intersection of interpreted structures with magnetic, radiometric and uranium anomalism. Commencement of Expanded Phase 3 Drilling and Trenching Program at Portland Creek Following integration of the geophysical, geological and geochemical datasets, Infini has since expanded the Portland Creek exploration program to approximately 5,000 m of diamond drilling supported by up to 1,000 m of trenching. During the Quarter, trenching and drilling activities have since commenced and remain underway, with Rodren Drilling and Coast Mountain Geological providing drilling and geological services respectively. Trenching represents the first systematic excavation program at Portland Creek and is designed to expose bedrock for structural mapping, radiometric assessment and channel sampling. Running in parallel with drilling, the program is intended to refine structural orientations and drill designs as new exposures and subsurface information become available. Phase 3 drilling has been designed to intersect the principal structures at favourable angles and at varying depths along their interpreted surfaces. Hole positions and orientations remain subject to adjustment based on trenching outcomes, oriented structural logging and downhole radiometric results.

Reynolds Lake and Reitenbach Lake Projects (100% owned, Saskatchewan Canada) The Reynolds Lake and Reitenbach Lake Uranium Projects collectively comprise 19 mineral claims covering a total footprint of 677 km2 on the eastern outboard margin of the Athabasca Basin in northern Saskatchewan. The projects are contiguous, with Reynolds Lake consisting of 12 claims (386 km2) and Reitenbach Lake consisting of 7 claims (291 km2) adjoining its northern boundary. The properties are underlain by Archean to Paleoproterozoic metamorphic and igneous rocks and are bisected by the crustal-scale Needle Falls Shear Zone, a major structural corridor separating the Wollaston Domain to the west from the Peter Lake Domain to the east. The Wollaston Domain is dominated by Paleoproterozoic siliciclastic metasediments including paragneiss, quartzite, and calc-silicate units, while the Peter Lake Domain contains Archean to Paleoproterozoic granitoid gneisses and supracrustal rocks. Both domains are strongly deformed and metamorphosed, with northeast- trending isoclinal folding and later cross-cutting north–south fault systems that provide structural complexity and potential pathways for hydrothermal fluid flow. Graphitic schists and gneisses, key lithologies known to host unconformity-associated uranium mineralisation, have been identified within the project area and are spatially associated with electromagnetic conductors, radiometric anomalies and elevated uranium-in-lake sediment samples. Recent exploration has confirmed primary uranium mineralisation at surface at Reitenbach Lake, while petrographic analysis has validated a structurally prepared and hydrothermally altered basement environment consistent with an unconformity-related uranium system. Regionally, the geological setting is considered analogous to uranium systems at Eagle Point and Rabbit Lake, where mineralisation occurs along graphitic shear zones at the boundary between Wollaston metasediments and granitoid basement. Quarterly Activities Report for the Period Ending 30 September 2026 ASX:I88 Figure 3: Location of the Reynolds Lake Reitenbach Uranium Projects relative to the world-renowned Athabasca Basin, synonymous with high-grade uranium deposits, and in close proximity to existing operations, access and infrastructure. Maiden Diamond Drilling Program Completed at Reynolds Lake and Reitenbach Lake During the Quarter, Infini completed the first-ever diamond drilling program across the Reynolds Lake and Reitenbach Lake tenements, comprising 16 holes for a total of 3,314 drill metres. The program provided the first subsurface test of the tenements located on the eastern margin of the Athabasca Basin and has materially improved understanding of the basement geology underlying priority surface and geophysical targets. Drilling tested locations where electromagnetic conductors coincided with magnetic lows, elevated uranium geochemistry and structural complexity. These targets included interpreted graphitic or sulphide-rich horizons, shear zones, fault intersections and deformation corridors considered prospective for basement-hosted uranium mineralisation. Quarterly Activities Report for the Period Ending 30 September 2026 ASX:I88 Figure 4: Indicative drillhole locations for the maiden diamond drilling program at Reynolds and Reitenbach Lake, targeting priority EM anomalies where magnetic features, structural complexity and uranium geochemical anomalism coincide. Geological Observations from Drilling at Reynolds and Reitenbach Lake Drilling intersected prospective basement lithologies including paragneiss, graphitic schist, graphitic gouge and orthogneiss. Several targeted conductive trends contained structurally disrupted intervals characterised by brittle faulting, brecciation, fracturing and local shear development. In a number of holes, graphitic and structurally prepared intervals were associated with chlorite, hematite, sericite, clay and local epidote alteration. Bleaching, recrystallisation and quartz veining were also observed adjacent to interpreted faults, indicating that several tested conductors lie within reactivated and hydrothermally altered basement corridors rather than representing graphitic horizons alone. These observations support key geological components of the Company's basement- hosted uranium exploration model and provide a strong basis for follow-up exploration. Quarterly Activities Report for the Period Ending 30 September 2026 ASX:I88 Reynolds Lake and Reitenbach Lake assay submission and follow-up assessment All core samples from the completed program have been submitted to the Saskatchewan Research Council (SRC), an ISO/IEC 17025:2017 accredited laboratory, for multi-element analysis. Assay results were originally expected in late Q3 CY2026, however based on updated timelines from SRC, these have been delayed due to significant laboratory congestion and extended turnaround times and are now expected in Q4 CY2026, subject to any further changes in laboratory processing schedules. Once received, the assay results will be integrated with geological logging, downhole gamma data, surface geochemistry, airborne EM, magnetics, radiometrics and structural interpretation. This integrated review will be used to evaluate the presence, grade and continuity of uranium mineralisation, refine exploration vectors and rank the drill-tested corridors. The review will also reassess the broader 80km EM conductor network and 15km by 3km prospective corridor using the new subsurface geological information. Outcomes will guide the design of potential Phase 2 drilling and targeted surface exploration across the highest-priority areas. Des Herbiers Uranium Deposit (100% owned, Québec Canada) The Des Herbiers Uranium Project consists of 66 non-contiguous claims totalling 36.25 km2. It is located within the Des Herbiers township, approximately 9km NW of the Baie-Johan-Beetz municipality and 52km ENE of the municipality of Havre St-Pierre on the Gulf of St. Lawrence in Quebec, Canada. The Project is situated in the Grenville Province of the Canadian Shield. The rocks underlying the immediate area are comprised of biotite rich granitic rocks, quartzites and quartzo- feldspathic gneisses that are derived from strongly metamorphosed sandstones and arkoses, amphibole rich gabbros and gneisses. Regional structures trend north to northwest and display large-scale curvilinear folding. Historical exploration and drilling have revealed an abundance of low grade, near surface, bulk tonnage uranium that contains a combined inferred mineral resource of 162Mt @ 123ppm U3O8 1 reported in accordance with the JORC Code (2012). No significant exploration activities were undertaken at the Des Herbiers Uranium Project during the reporting period. Yeelirrie North Uranium Project (100% owned, Western Australia) The Yeelirrie North Project currently consists of exploration licence E53/2188, E53/2368 and prospecting licence P53/1703, covering an area of ~329km², located approximately 70km southwest of Wiluna, Western Australia. The Company currently has three exploration licence applications in progress and if successfully granted, the remaining new exploration licence applications will see the Company’s Project size increase to a total area of ~746km2. The Yeelirrie Project is located near the northern extremity of the Archaean Norseman Wiluna greenstone belt of the Yilgarn Craton. The project is highly prospective for hosting high-grade uranium mineralised calcrete and lies within the same geological domain as the world class Yeelirrie Uranium Deposit hosting 128.1Mlb U3O8 at an average ore grade of 1,500 ppm U3O8 2. No significant exploration activities were undertaken at the Yeelirrie North Uranium Project during the reporting period. Bellah Bore East Uranium Deposit (100% owned, Western Australia) The Bellah Bore East deposit is approximately 500m x 150m in size and located within prospecting license P 53/1703, comprising 92.67 hectares. The licence is situated within the western edge of the Company’s already existing E 53/2188 tenement ~60km southwest of Wiluna (Yeelirrie Project). The deposit is hosted by calcrete and comprises a historical inferred mineral resource in accordance with the JORC Code (2004) (it is noted that these exploration results reported under the JORC 2004 code may not conform to the requirements of the JORC Code 2012). Mineralisation is reported as open in the northeast. Carnotite is identified as the primary ore mineral in historical drilling. No significant exploration activities were undertaken at the Bellah Bore East Uranium Project during the reporting period. Tinco Uranium-Niobium Project (75% Tinco North, 100% Tinco South, Saskatchewan Canada) The Tinco Uranium‑Niobium Project lies to the south‑southwest of the Athabasca Basin and is underlain by the Mudjatik Domain, composed mainly of granitoid felsic gneisses that form the basement to narrow belts of supracrustal sedimentary and volcanic rocks. Two principal uranium mineralisation styles have been recognised in the area, including remobilised basement occurrences and supracrustal occurrences, with previous mapping identifying lenses of radioactive pegmatite up Quarterly Activities Report for the Period Ending 30 September 2026 ASX:I88 to 1.5 m in width and historical grab samples grading up to 600 ppm U3O8 and 0.5% Nb. More recently, Infini’s heliborne magnetic, radiometric and time‑domain electromagnetic survey has delineated magnetic and radiometric trends, major structures and stratigraphic relationships, highlighting a prominent north–south trending shear zone hosting the historical mineralised grab sample and several large ovoid magnetic features that together define a large U‑Nb target area for future exploration and follow‑up surface geochemical work. No significant exploration activities were undertaken at the Tinco Uranium-Niobium Project during the reporting period. Paterson Lake Lithium Project (100% owned, Ontario Canada) The Paterson Lake Project is located within the highly prospective Archean Separation Lake Greenstone Belt of the Superior Province of Ontario, Canada. The Project has been documented to contain abundant rare-metal bearing pegmatites including seven named petalite bearing pegmatites and up to 50 unnamed pegmatites that require investigation. Historical outcrop grab sample results include results up to 4.43% Li2O and the best reported historical drill intercept to date of 8m @ 3.12% Li2O. The Separation Rapids Lithium Deposit of Avalon Advanced Materials/Sibelco joint venture is located within 2km of the project boundary. No significant exploration activities were undertaken at the Paterson Lake Lithium Project during the reporting period. Valor Lithium Project (Québec Canada) The Valor Project covers an area of approximately 125km2 in southwest Québec, approximately 40km north-west of Val- d’Or. The project is situated on the Archean Preissac Lacorne batholith, a syn-to post-tectonic intrusion that was emplaced in the Southern Volcanic Zone of the Abitibi Greenstone Belt of the Superior Province of Québec. To the north the batholith is bounded by the Manneville Fault and to the south by the Cadillac Fault and the eastward extension of the Porcupine Destor Fault. The batholith, which is a composite body has associated pegmatites and quartz veins. After completing soil sampling activities, the company has now identified several large scale LCT MMI geochemical anomalies. Following a review of exploration results and the Company’s strategic focus in actively exploring Portland Creek, Reynolds Lake and Reitenbach Uranium Projects, Infini elected to relinquish the Valor Project upon expiration of individual tenement leases. Schedule of Mining Tenements The Company’s tenement and claim schedule is provided in Appendix 1.
