Further Priority Targets Identified at Reynolds Lake Uranium Project

Comprehensive desktop study completed, integrating historical lake sediment geochemistry, regional airborne radiometric data and results from the recently flown TDEM survey.

Geophysical interpretation highlights significant shear zones and a potential network of cross-cutting N-S trending faults considered to be important structural controls for uranium mineralisation.

Multiple large-scale electrical conductors (largest >10 km long) coincident with radiometric anomalies and geochemical anomalism along key structural corridors, collectively highlighting compelling targets for potential shallow unconformitystyle uranium mineralisation on the outboard edge of the Athabasca Basin.

Field program commencing September 2025, to include systematic soil sampling of anomaly zones, rock chip sampling of outcrop and detailed geological mapping.

Timing of the Reynolds Lake field program highly complementary to Infini’s upcoming Phase 2 drilling campaign at the Portland Creek Uranium Project, with mobilisation planned to commence in the first week of September 2025.

Program designed to advance the highest-priority targets to drill-ready status for a potential Phase 1 drill program at Reynolds Lake in early 2026.

Infini Resources Limited (ASX:188) (“Infini” or the “Company”) is pleased to announce the results of a recently completed study at the Reynolds Lake Uranium Project (“Reynolds Lake” or the “Project”), which has successfully identified multiple exploration target areas for follow-up fieldwork. A program consisting of soil and rock sampling, together with geological mapping, is scheduled to commence in September 2025.

Study Results

The integrated review of available datasets has highlighted 14 high-priority target areas and several secondary zones across the Reynolds Lake project, illustrated in Figure 1 below. Key findings include:

• Lake sediment geochemistry: historic data reveal numerous anomalous uranium values, many of which coincide with favourable structural corridors.

• Radiometrics: regional airborne surveys highlight distinct uranium-channel responses associated with interpreted fault structures.

• TDEM geophysics: multiple EM conductors have been mapped, several of which overlap with geochemical and radiometric anomalies, suggesting potential zones of structurally controlled mineralisation.

• Structural interpretation: has identified broad shear zones and cross-cutting N–S trending faults throughout the project area. These structures are interpreted as potential conduits for mineralising fluids and represent high-priority zones for on-ground exploration.

Together, these datasets provide a compelling, multi-layered exploration model for Reynolds Lake.

Infini’s Chief Executive Officer, Rohan Bone, said: "The Reynolds Lake study has delivered exactly what we hoped – clear, coincident anomalies across multiple datasets that provide us with strong vectors to uranium mineralisation. With structural interpretation further highlighting key shear zones and fault corridors, we now have a robust framework to guide targeted fieldwork. By commencing fieldwork in September, we are well placed to advance these targets rapidly towards drilling and deliver the next stage of growth for Infini."

Upcoming Field Program

To advance the newly defined targets, Infini has scheduled a focused field campaign to include:

• Soil sampling on systematic grids across anomaly zones;

• Rock chip sampling of outcropping uranium-bearing lithologies;

• Geological mapping to refine interpretations of shear zones and fault structures;

• Using pXRF in the field to guide the fieldwork programs ; and

• Submitting samples for laboratory analysis using industry-standard methods for uranium and pathfinder elements.

The program is expected to be completed in Q3 2025, with assay results anticipated in Q4 2025.

About Reynolds Lake Uranium Project

The Reynolds Lake Uranium Project, as shown in Figure 2, comprises 12 claims covering 386 km², located on the eastern outboard edge of the Athabasca Basin in northern Saskatchewan — a benchmark region globally renowned for high-grade uranium. The property lies approximately 40 km east of the community of Wollaston Lake. It is flanked by the Keeping Lake Project to the north and the Jewison Lake Project to the south.

Figure 2: Location of the Reynolds Lake Uranium Project relative to the world-renowned Athabasca Basin, synonymous with high-grade uranium deposits, and in close proximity to existing operations, access and infrastructure.

Exploration outside the basin margin is driven by evidence that the geological conditions necessary for unconformity-type deposit formation — namely, reactivated basement structures, graphitic metasedimentary rocks, and the presence of hydrothermal fluids — extend beyond the current limits of Athabasca sandstone cover and are related to the paleo conditions when the Thelon and Athabasca basins were joined in the Paleoproterozoic era, (1.7 to 1.6 Ga).

The Reynolds Lake Project is underlain by Archean felsic gneisses, which are overlain by a sequence of Lower Proterozoic metamorphic rocks of the Wollaston Domain. This sequence includes quartzite, mafic gneiss, meta-arkose, and calc-silicate units. The structural fabric of the area is dominated by northeasttrending isoclinal folding. A major structural feature, the Needle Falls Shear Zone, transects the project area with a northeast-southwest orientation. Graphitic schists and gneisses — critical host rocks for unconformity-type uranium mineralisation — have been identified at several locations across the property.
