Portland Creek Soil Samples Hit 7.5% Uranium Oxide, Phase 2 Drilling Set for Q3

Refining the Exploration Model

Infini Resources Limited (ASX, I88) has taken a decisive step forward in its quest to unlock the potential of the Portland Creek Uranium Project by engaging a team of structural geology and uranium exploration specialists. This move follows the completion of a Phase 1 diamond drilling program that, while promising, left key questions unanswered; most notably the source of exceptionally high uranium concentrations detected in soil samples.

The company is fast-tracking a comprehensive review of geological, geochemical, and geophysical data to refine its exploration model. This review integrates recent drilling results with extensive soil sampling and airborne magnetic surveys conducted in 2024, aiming to sharpen target generation ahead of a planned Phase 2 drilling campaign in the third quarter of 2025.

Unraveling the High-Grade Anomalies

One of the most striking features of the Portland Creek Project is the presence of uranium-in-soil anomalies reaching up to 74,997 ppm (approximately 7.5% U3O8) along a 6-kilometre corridor known as the Trident Lake Zone. These values are extraordinarily high and remain unexplained by the initial drilling, which did not intersect the primary uranium-bearing structures due to drill holes being oriented subparallel to the dominant shear zones.

Infini has engaged Newexco structural geologists to analyze these data and provide a framework for future exploration. Additionally, uranium expert Mark Couzens, with over 15 years of experience including involvement in major discoveries such as the Four Mile Uranium Deposit, has been brought on board to interpret the high-grade soil anomalies and associated geological features. Couzens notes that such elevated uranium levels in soils are indicative of a significant, high-grade primary uranium orebody nearby, underscoring the project's potential.

Preparing for Phase 2 Drilling

With the structural and geochemical reviews underway, Infini is preparing to finalize its exploration model and drill targets for Phase 2. The upcoming drilling campaign is expected to test the primary shear-hosted uranium system hypothesis and explore alternative deposit styles suggested by the early expert assessments.

CEO Rohan Bone expressed optimism about the project’s prospects, highlighting the combination of geological indicators such as hydrothermal alteration, uranium pathfinder elements, radon gas anomalies, and radiometric data that collectively point to a potentially large and high-grade uranium system. The Phase 2 drilling, anticipated to commence later in Q3 2025, will be critical in validating these interpretations and advancing the project toward resource definition.

Strategic Significance of Portland Creek

Located within the Precambrian Long-Range Complex of Newfoundland, the Portland Creek Project covers 149 square kilometres and hosts a significant regional uranium anomaly first identified in the 1970s. Infini’s recent work has confirmed and expanded upon these historical findings, positioning the project as a compelling target in the global uranium exploration landscape.

As the company moves toward its next phase of exploration, the market will be watching closely for results that could reshape the valuation and strategic outlook for Infini Resources, especially given the growing global demand for uranium in the context of clean energy transitions.
