Infini Resources lights up next-generation uranium targets in Canada

First modern helicopter-supported geophysical survey flown over 252 km² of Infini’s tenements at Portland Creek.

Infini Resources (ASX: I88) has narrowed its hunt for a district-scale uranium discovery at its Portland Creek project in Newfoundland, Canada, after completing the first modern helicopter-supported geophysical survey across the broader tenure.

The company says the new dataset, combined with results from its 5310m phase two drilling campaign, has improved its understanding of the system and significantly upgraded drill targeting ahead of an expanded phase three program later this year.

The airborne survey covered 2230 line kilometres across 252 square kilometres of the company’s 328-square-kilometre Portland Creek project. Helicopter-borne electromagnetic and magnetic sensors were flown on tight 100m and 200m line spacings across the tenure.

Infini also received the final assays from its 17-hole phase two campaign. Highlights included 192 parts per million (ppm) uranium oxide over 0.5m, 180ppm uranium oxide over 0.45m and 107ppm uranium oxide over 0.62m.

Notably, the latter result sat within 300m of near-continuous uranium anomalism, making it the most extensive mineralised intersection returned from the program. Combined drilling has now confirmed uranium enrichment across more than 6km of strike.

The biggest prize from the work appears to be the emerging geological model. Integration of drilling, geochemistry, alteration studies and 2814 structural measurements has strengthened management’s view that Portland Creek hosts a structurally controlled, multi-stage hydrothermal uranium system developed within granite.

The analysis indicates uranium tends to accumulate where northwest-southeast structures intersect east-west fracture sets. These structural crossroads appear to have acted as fluid pathways and traps for uranium-bearing fluids.

While the electromagnetic survey did not identify any major conductive zones, the company believes the magnetic data will help pinpoint fault structures and altered rocks commonly associated with hydrothermal uranium mineralisation.

Management believes the dataset could deliver a step-change in understanding the granite host by highlighting granitic contacts, cross-cutting fault structures and alteration footprints across a broad corridor that remains largely untested by drilling.

The integrated interpretation has already elevated step-out drilling around a standout hole from phase two drilling to the top of the phase three target list. Starting from just 35 metres downhole, the hole delivered a long run of elevated uranium mineralisation that continued across multiple sections to depths beyond 300m, with assays peaking at 347 ppm uranium.

The completion of the airborne geophysics survey over Infini's broader Portland Creek tenement package is an important milestone for the Company and a significant step forward in our ability to identify new targets across what we believe is a substantially underexplored structural system.   Infini Resources chief executive officer Rohan Bone

The latest geophysical work builds on a growing body of evidence pointing to a sizeable uranium system at Portland Creek. The project sits within Newfoundland's Precambrian Long-Range Complex, where previous exploration outlined a 6km corridor of anomalous uranium and radon signatures.

Soil sampling previously defined an 800m by 100m anomaly that returned assays up to 74,997 parts per million uranium oxide. The latest geophysical and drilling interpretations are now helping management trace the structural controls that may connect those surface anomalies to uranium mineralisation at depth.

The next phase of exploration will begin with a project-wide airborne radiometric survey to complete the geophysical dataset. The geos will then complete structural mapping, prospecting and rock-chip sampling before the company applies for permitting for a 5000m phase three diamond drilling program in the third quarter.

Uranium continues to benefit from strengthening long-term fundamentals as governments increasingly embrace nuclear power to bolster energy security and support decarbonisation goals. With new mines scarce and demand forecasts rising, explorers capable of delivering discoveries in tier-one jurisdictions such as Canada are attracting growing attention from investors and the broader nuclear fuel sector.

Portland Creek is rapidly evolving from a target-generation exercise into a focused structural uranium hunt. Armed with project-wide geophysics, a sharpened geological model and clearly defined structural sweet spots, Infini is lining up its next drill campaign with far greater precision. If the targets deliver, Portland Creek could quickly emerge as Newfoundland's next uranium discovery story.
