Catalysts And Upcoming Events ► Phase 2 drill program now underway at Portland Creek – Minimum 2,500m program designed to unlock a potential globally significant uranium discovery. ► Reynolds Lake maiden field program launched – systematic sampling and mapping to fast-track highpriority targets towards drilling in 2026. ► Strong long-term uranium price outlook linked to a global supply deficit. ASX: I88 Infini Resources 04 Newfoundland – A Tier One Underexplored Jurisdiction ► Infini’s Portland Creek Uranium Project is located in the pro-mining province of Newfoundland and Labrador, Canada. ► Uranium registered on the Newfoundland Government’s Critical Minerals List. ► Government exploration incentives available for uranium companies, with Infini Resources receiving a 2025 Junior Exploration Assistance (JEA) grant. ► Supportive local infrastructure and workforce, with low sovereign risk relative to global peers. ► Portland Creek is a historical mining region with the Daniel’s Harbour Mine located only ~15km to the north having been in operation from 1975-19901. 1.

Daniels Harbour Project https://www.ubiqueminerals.com/properties/daniels-harbour/ ASX: I88 Infini Resources 05 Potential for a Major Greenfields Discovery at Portland Creek Dominant Land Position (149 km2) ► Consolidated ground position across entire mineralised corridor. ► Potential for uranium mineralisation to exist outside of the Falls Lake Prospect with 4 additional areas of interest. ► Historic uranium exploration (1970s) identified multiple anomalies, but modern techniques underutilised. Multiple Geological Indicators ► >6 km uranium-in-soil corridor – peaking at 74,997 ppm (~7.5%) U₃O₈, among the highest grades recorded globally at surface. ► Stacked anomalism across multiple datasets – radon gas, Pb isotopes, LREE pathfinders, radiometric highs and uranium-inlake sediments all point to a large, robust uranium system. ► Compelling evidence of primary mineralisation – hydrothermal alteration and mineralised veins historically assaying up to 2,180 ppm U₃O₈. ASX: I88 Infini Resources 06 Refined Exploration Model Points to Untested High-Grade Potential ► Phase 1 drilling intersected hydrothermal alteration and uranium pathfinders, but the primary structures remain untested. ► Exploration model significantly strengthened after engaging structural geology & uranium specialists to review soils, radiometrics, magnetics, and structural mapping datasets. ► Refined exploration model identified E–W fault corridors as the critical controls on uranium-bearing hydrothermal veins. ► Interpretation points to potential brecciation and stockwork veining along these faults – a hallmark of high-grade shearhosted uranium systems. ► Phase 2 drill program now underway to systematically test these high-impact targets with discovery-making potential. ASX: I88 Infini Resources 07 Phase 2 Drilling Targeting a Tier-One Uranium Discovery ► Targeted drill program launched – minimum 2,500m of diamond drilling across 12 of the priority targets within a uranium-rich 6 km corridor. ► Phase 2 drilling targeting primary uranium mineralisation along untested E–W fault corridors – the interpreted conduits for the project’s extraordinary soil grades (up to 7.5% U₃O₈). ► Drillhole design guided in real-time by geological mapping and rock-chip sampling to maximise discovery potential. ► Agile and scalable program – designed to expand rapidly on early success and test mineralisation to depth. ► Backed by seasoned contractors: Rodren Drilling (47 years experience) and Coast Mountain Geological (32 years experience). ► Clear objective: deliver a breakthrough uranium discovery at Portland Creek — high-grade, at-surface, and opening up an entirely new globally significant uranium jurisdiction. ASX: I88 Infini Resources 08 Pipeline of Projects in the World’s Richest Uranium Province ► Reynolds Lake (386 km²): EM conductors >10 km long coincident with radiometric and geochemical anomalies; maiden field program now underway. ► Reitenbach Lake (291 km2): historical uranium showings; multiple EM conductors; high-priority target area for future fieldwork. ► Boulding Lake (254 km2): airborne magnetic survey completed; data being advanced to define targets for further exploration. ► Outstanding exposure to the world’s premier uranium province, with multiple near-term catalysts and discovery opportunities. ASX: I88 Infini Resources 09 Rare Shallow Discovery Opportunity at Reynolds Lake Prospective shallow unconformity-style deposit ► Eastern margin of the Athabasca Basin, proximal to the highly prospective Needle Falls Shear Zone. ► Multiple >10 km EM conductors coincident with radiometric highs and anomalous lake sediments – strong indicators of a large uranium system. ► Geophysics interpretation indicates the EM anomalies could be as shallow as 20m below surface. Field program underway at Reynolds Lake ► Systematic program launched to collect ~1,600 soil and rock-chip samples. ► Detailed mapping of shear zones and cross-cutting N–S faults to confirm key structural controls on mineralisation. ► Designed to fast-track multiple targets to drill-ready status for maiden drilling in 2026. ► Assay results expected in Q4 2025, providing the next major discovery catalyst. ASX: I88 Infini Resources 010 Positioned for Discovery, Powered by Demand ► Infini actively testing and positioned for discovery – dual exploration campaigns underway in tier-one uranium jurisdictions. ► Portland Creek Phase 2 drill program now underway, highpriority targets being tested in pursuit of a significant uranium discovery. ► Reynolds Lake maiden field program underway, advancing multiple large-scale anomalies to drill-ready status for 2026. ► Continuous activity ahead, assay results from Portland Creek and Reynolds Lake expected in Q4 2025. ► Clear value proposition – exposure to transformational uranium discovery at a time of rising global demand for nuclear energy.
