Infini Resources Uncovers Widespread Uranium Zones at Portland Creek
Infini Resources has expanded its drilling program at the Portland Creek Uranium Project, revealing multiple uranium-bearing zones across a broad corridor. Early results suggest a large, district-scale uranium system with promising polymetallic potential.
- Phase 2 drilling extended to 3,910 metres, surpassing initial plans
- Visible uranium and elevated pXRF readings up to 1.20% U detected
- Multiple drill holes over a 6 km corridor show widespread mineralisation
- Polymetallic signatures include zinc, copper, molybdenum, and titanium
- Airborne geophysical survey and expanded 2026 drilling campaign planned
Expanded Drilling Reveals District-Scale Uranium Potential
Infini Resources Limited (ASX – I88) has reported encouraging progress from its Phase 2 diamond drilling program at the Portland Creek Uranium Project in Newfoundland, Canada. Originally planned for 2,500 metres, the drilling has now extended to 3,910 metres, testing five of twelve priority targets within a 6-kilometre corridor marked by strong uranium-in-soil anomalies and radiometric highs.
The company has intersected visible uranium minerals, including uraninite, and recorded elevated uranium values using portable XRF (pXRF) technology, with spot readings reaching up to 1.20% uranium in some drill holes. These results, spread across multiple targets separated by over a kilometre, support the interpretation of a large, structurally controlled uranium system with district-scale potential.
Polymetallic Mineralisation Adds to Project Appeal
Beyond uranium, the drilling has revealed polymetallic signatures including zinc, copper, molybdenum, and titanium, associated with hydrothermal alteration zones. Notably, some fracture zones have shown zinc concentrations up to 8,000 ppm and molybdenum up to 2.38% in previous holes. This multi-metal enrichment suggests the presence of a fertile magmatic-hydrothermal system capable of transporting a suite of critical metals, potentially enhancing the project's economic prospects.
Infini’s CEO, Rohan Bone, highlighted the significance of these findings, stating that the program has surpassed expectations and that Portland Creek is rapidly emerging as one of Canada’s most compelling early-stage uranium projects. The presence of multiple metals within structurally distinct corridors indicates a broad mineralised system rather than isolated deposits.
Next Steps and Future Exploration
Drilling is expected to continue until early December 2025, weather permitting, with assay results from earlier holes anticipated later this quarter. These laboratory-confirmed assays will be critical to validate the preliminary pXRF readings and refine the understanding of mineralisation continuity and grade distribution.
In parallel, Infini is planning a high-resolution airborne geophysical survey, including magnetics, time-domain electromagnetic (EM), and radiometric measurements, scheduled for late Q4 2025 or early Q1 2026. This survey aims to enhance structural and lithological targeting across both existing and newly acquired tenements.
Looking ahead, the company intends to launch an expanded drilling campaign in 2026 to further evaluate the most prospective targets and delineate the full extent of the polymetallic uranium system at Portland Creek.
Context and Caution
The Portland Creek Project covers 251 square kilometres within the Precambrian Long-Range Complex, an area with a history of uranium anomalies dating back to the 1970s. Infini has systematically built on this legacy with modern exploration techniques and a growing dataset.
However, the company cautions that all uranium grades reported so far are based on qualitative pXRF spot measurements and visual observations, which are not substitutes for definitive laboratory assays. The true economic potential will depend on assay-confirmed grades, mineralisation thickness, and continuity, which remain to be fully established.
Bottom Line?
As assay results and geophysical data emerge, Portland Creek’s true scale and value will come into sharper focus, potentially reshaping Infini’s growth trajectory.
Questions in the middle?
- Will laboratory assays confirm the high-grade uranium indicated by pXRF readings?
- How extensive and continuous are the uranium and polymetallic mineralised zones across the 6 km corridor?
- What insights will the upcoming airborne geophysical survey provide for targeting and resource definition?
