Infini Resources Limited (ASX:I88) (“Infini” or the “Company”) is pleased to report on its activities for the quarter ended 30 June 2026 (the “Quarter”). During the Quarter, the Company advanced its Canadian uranium portfolio through the commencement of a maiden diamond drilling program at the Reynolds Lake and Reitenbach Lake Uranium Projects in Saskatchewan and the completion of a project‑wide airborne EM and magnetic survey at the flagship Portland Creek Uranium Project in Newfoundland. At Reynolds Lake and Reitenbach Lake, the maiden drill program commenced targeting high‑priority zones where EM conductors, magnetic lows, structural corridors and uranium geochemical anomalism coincide, including the high‑grade 1.90% U3O8 Titus Prospect. This drilling represents the first test of a large, underexplored and highly prospective potential uranium system on the eastern margin of the Athabasca Basin, marking a key milestone as the projects transition from target generation to drill testing. At Portland Creek, Infini completed 2,230 line‑km of helicopter‑supported airborne EM and magnetic surveying over approximately 252 km2 of its tenement package and received the final laboratory assays from its 5,310m, 17‑hole Phase 2 diamond drilling program. Integration of the structural and assay datasets has confirmed uranium enrichment over more than 6 km of strike within a structurally controlled hydrothermal system, significantly improving the geological model and directly informing the design of an expanded 5,000m Phase 3 drilling program targeted to commence in Q3 CY2026. Quarterly Activities Report for the Period Ending 30 June 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 the recently completed Phase 2 drill program. Final Phase 2 Assays Confirm Shear-Hosted Exploration Model During the Quarter, Infini received the final laboratory assay results from its completed 5,310m Phase 2 diamond drilling program at Portland Creek, completing the full analytical dataset from 17 drillholes. These final assay results confirmed elevated uranium anomalism, including up to 192 ppm U3O8 over 0.5m at 53m (PCDD25-022), across additional target areas. When combined with earlier assay batches, the complete Phase 2 dataset confirms uranium enrichment across more than 6 km of strike, reinforcing the interpretation of Portland Creek as a structurally controlled, multi-stage hydrothermal uranium system developed within granite. Integration of the geochemical and structural datasets has significantly improved the Company’s understanding of the controls on mineralisation, with uranium preferentially developed at intersections of key fracture sets and associated hydrothermal alteration zones. Project-Wide Airborne Geophysics Completed at Flagship Portland Creek Project During the Quarter, Infini completed a project-wide airborne electromagnetic (EM) and magnetic survey at the Portland Creek Uranium Project in Newfoundland, representing the first modern helicopter-supported geophysical survey across the Project’s expanded tenement package. A total of 2,230 line km of surveying was completed over approximately 252 km2, delivering a high-resolution dataset that significantly advances structural interpretation and uranium target generation across the broader Project area. Interpretation of the newly acquired data has provided important insights into the subsurface geological architecture at Portland Creek. In particular, the magnetic dataset is being used to map major fault sets and structural intersections, delineate resistive trends, and identify demagnetised zones that may reflect hydrothermal alteration within the granite host, materially improving the Company’s geological model and sharpening target definition beyond areas tested to date. The Company also commenced a 737 line-kilometre high-resolution airborne radiometric survey over a defined survey area to complement the EM and magnetic datasets. Preliminary interpretation of the airborne magnetic, EM and radiometric data is underway and is already providing significant insight into the subsurface geological framework at Portland Creek. The combined geophysical dataset is being used to map major fault sets and structural intersections, delineate resistive trends, and identify demagnetised and radiometrically anomalous zones that may reflect hydrothermal alteration within the granite host. To refine target generation, these geophysical interpretations are being cross-referenced with historical lake sediment and soil geochemistry data, as well as results from the Company’s Phase 1 and Phase 2 drill programs. Quarterly Activities Report for the Period Ending 30 June 2026 ASX:I88 Field activities are scheduled to commence in Q3 CY2026 and will focus on ground-truthing priority geophysical targets through mapping, sampling and prospecting, ahead of the planned commencement of the Phase 3 drill program later in Q3 CY2026. Collectively, these datasets materially help de-risk the next phase of exploration of this highly prospective potential large-scale system of uranium mineralisation.

Quarterly Activities Report for the Period Ending 30 June 2026 ASX:I88 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 June 2026 ASX:I88 Maiden Diamond Drilling Program Commenced at Reynolds Lake and Reitenbach Lake During the Quarter, Infini commenced its maiden diamond drilling program at the Reynolds Lake and Reitenbach Lake Uranium Projects in northern Saskatchewan, the first time these projects have ever been drill tested. The program represents the initial drill test of a large, unexplored and highly prospective potential uranium system on the eastern margin of the Athabasca Basin and marks a key milestone as the projects transition from target generation to systematic drill testing of high‑conviction targets. The program is focused on zones where multiple mineralisation vectors coincide, including EM conductors, magnetic lows, structurally complex corridors and elevated uranium geochemical anomalism, with particular emphasis on the high‑grade 1.90% U3O8 Titus Prospect area. Drill collars have been positioned to test a range of structural settings, including conductor intersections, demagnetised zones and interpreted dilation sites along key shear corridors, with the objective of maximising technical information, rapidly vectoring toward the most prospective parts of the system and informing subsequent phases of exploration at Reynolds Lake and Reitenbach Lake.

Quarterly Activities Report for the Period Ending 30 June 2026 ASX:I88 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 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. Quarterly Activities Report for the Period Ending 30 June 2026 ASX:I88 No significant exploration activities were undertaken at the Paterson Lake Lithium Project during the reporting period. Valor Lithium Project (50% owned, earn-in up to 100%, 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. No significant exploration activities were undertaken at the Valor Lithium Project during the reporting period.
