Infini Resources has confirmed compelling radiometric anomalies and structural targets at its Portland Creek project in Newfoundland while completing maiden drilling at its Saskatchewan projects, setting the stage for a busy 2026 drilling campaign.
- Portland Creek field program confirms strong radiometric anomalies
- Phase 3 diamond drilling and trenching planned for Q3 2026
- Maiden drilling at Reynolds and Reitenbach Lakes intersects prospective structures
- Assays pending for both Canadian project clusters
- Exploration model increasingly de-risked with structural and hydrothermal evidence
Portland Creek Field Program Validates Structural Uranium Targets
Infini Resources Ltd (ASX:I88) has delivered a robust field update from its Portland Creek Uranium Project in Newfoundland, confirming multiple airborne radiometric anomalies with peak handheld spectrometer readings up to 9,400 counts per second against a background of 500–800 cps. The 2026 field campaign comprised 465 geological stations and approximately 283 km of ground traverses, systematically mapping elevated radioactivity within structurally prepared granite and leucogranite veins.
These elevated radiometric responses are consistently tied to fractured and bleached granite, leucogranite veins, and sericitic fault gouge, supporting a structurally controlled hydrothermal uranium model. Portable XRF screening returned uranium values up to ~2,800 ppm U, with petrographic analysis independently confirming the associated alteration assemblage. A total of 86 rock samples have been submitted for laboratory assays, expected in Q3 2026.
Upcoming Phase 3 Drilling and Trenching to Test High-Grade Anomalies
With preparatory work advanced, Infini is poised to commence a ~5,000 m Phase 3 diamond drilling program in Q3 2026, alongside a trenching campaign targeting multiple prospects, including the high-grade Falls Lake anomaly which yielded surface soil assays peaking at 74,997 ppm (7.5% U₃O₈). Trenching aims to expose bedrock beneath shallow cover to identify potential mineralisation sources, complementing the deep structural testing planned via drilling.
The integration of field observations, geochemical data, and airborne geophysical surveys will refine and prioritise drill targets, sharpening the exploration focus after two prior phases of drilling and geophysical work. This approach aims to de-risk the project by confirming structural corridors and hydrothermal alteration indicative of uranium mineralisation.
Maiden Drilling at Reynolds and Reitenbach Lakes Reveals Prospective Basement Structures
In Saskatchewan, Infini has completed its inaugural diamond drilling program at the Reynolds Lake and Reitenbach Lake Uranium Projects, with 16 holes totaling 3,314 m drilled. This first subsurface test intersected reactivated graphitic structures and hydrothermal alteration assemblages including chlorite, hematite, and sericite, consistent with those hosting uranium deposits along the Athabasca Basin's eastern margin.
Drilling confirmed prospective basement lithologies such as paragneiss and graphitic schist, with structurally disrupted zones marked by faulting, brecciation, and quartz veining. These geological features align with Infini’s system-scale exploration model and analogue deposits like Eagle Point and Rabbit Lake, though assay results remain pending and are expected late Q3 2026.
Assay Results Awaited to Guide Next Exploration Steps
All core samples from the Saskatchewan drilling have been submitted to the Saskatchewan Research Council, an ISO/IEC accredited laboratory, with assays delayed due to regional laboratory congestion. Once received, results will be integrated with geological, geochemical, and geophysical data to refine exploration vectors and prioritise targets for potential Phase 2 drilling and surface work.
Infini’s CEO, Rohan Bone, highlighted the technical progress, noting the strong pipeline of catalysts ahead, including Portland Creek’s Phase 3 drilling and Reynolds-Reitenbach maiden drill assays. The company’s strategic technical advisor, Andy Yackulic, underscored the significance of intersecting hydrothermal and structurally reactivated zones, which materially upgrade the projects’ prospective scale.
Canadian Uranium Portfolio Positioned for Active Second Half of 2026
With assay results pending and major drilling campaigns imminent, Infini Resources is entering a critical phase of exploration in two distinct Canadian uranium provinces. Portland Creek’s structurally controlled hydrothermal uranium system is increasingly well-defined, while the Saskatchewan projects have delivered encouraging geological evidence of basement-hosted mineralisation potential. The coming months will be pivotal in translating these early-stage findings into a clearer picture of economic viability.
Bottom Line?
Infini’s advancing Canadian uranium programs set a foundation for meaningful assay results and drilling milestones in late 2026, but confirmation of mineralisation continuity and grade remains the key hurdle.
Questions in the middle?
- Will the upcoming assay results confirm the extent and grade of uranium mineralisation at Portland Creek and Saskatchewan projects?
- How will Infini prioritise drill targets based on integrated structural, geochemical, and geophysical data?
- What impact will regional laboratory processing delays have on exploration timelines and investor sentiment?
