Infini Resources completes radiometric survey to sharpen Portland Creek uranium targets

Completion of High-Resolution Radiometric Survey

Infini Resources Ltd (ASX:I88) has wrapped up a detailed airborne radiometric survey over its Portland Creek Uranium Project in Newfoundland, Canada, delivering a modern dataset that significantly upgrades the project's geophysical foundation. The heliborne survey, flown by Axiom Exploration Group Ltd, covered 737 line-kilometres at 200-metre spacing, complementing previous electromagnetic and magnetic surveys to sharpen the geological picture.

Preliminary interpretation of the combined radiometric, magnetic, and electromagnetic data is already yielding insights, mapping major fault sets and structural intersections. Notably, magnetic-low zones interpreted as magnetite-to-hematite alteration halos are being correlated with radiometric highs to pinpoint potential uranium-bearing hydrothermal fluid pathways within the granite host rock.

Field Program Targets Structural Controls on Uranium Mineralisation

With the survey complete, Infini has deployed geological crews to ground-truth priority radiometric anomalies and refine the understanding of structural and geological controls across its 329 km² tenure. Fieldwork focuses on outcropping fault zones, fracture networks, and breccia bodies, particularly where demagnetised zones, radiometric highs, and uranium-in-soil anomalies coincide.

Rock chip and selective soil sampling aim to characterise hydrothermal alteration and pathfinder elements like molybdenum, zinc, and copper. These geochemical vectors will integrate with subsurface data from earlier drill programs to guide the upcoming Phase 3 diamond drilling campaign.

Phase 3 Drilling on Track for Q3 2026

Infini plans to commence an expanded Phase 3 diamond drilling program in the third quarter of 2026, targeting a structurally controlled, district-scale uranium system within the Precambrian Long-Range Complex of Newfoundland's Humber Tectonic-Stratigraphic Zone. This campaign represents a step-up in testing high-priority structural corridors and intersection zones identified by integrated geophysical and geochemical datasets.

CEO Rohan Bone emphasised the significance of the integrated dataset in delivering sharper drill targets, aiming to build on the 2025 drilling results and convert technical understanding into meaningful discoveries for shareholders.

Project Background and Historical Anomalies

The Portland Creek Project covers a large regional uranium anomaly first identified in the 1970s, with historic soil anomalies reaching up to 74,997 ppm U3O8 at the Falls Lake Prospect. The project’s geological setting, dominated by metaquartzite and paragneisses intruded by leucocratic granite, is considered highly favourable for structurally hosted hydrothermal uranium mineralisation.

Previous exploration, including airborne geophysics and drilling, has delineated a 6 km zone of anomalous uranium and radon gas. The current work builds on this foundation, leveraging modern survey techniques to refine the geological model and target generation.

Next Steps and Regulatory Progress

Infini is progressing regulatory approvals and logistical preparations for the Phase 3 drill program while continuing detailed structural mapping and sampling to finalise drill collar locations. The company's approach integrates airborne geophysics with ground-based geological and geochemical data to maximise the efficiency and effectiveness of upcoming drilling.

This methodical advance aims to test the most prospective structural corridors within a district-scale uranium system, potentially unlocking significant new mineralisation in a globally relevant uranium province.
