Portland Creek: Field Program Delivers on Every Objective
According to the announcement, the 2026 field program at Portland Creek was designed to systematically assess priority airborne radiometric anomalies on the ground. The helicopter-supported program covered substantial ground:
- 465 geological observation stations recorded across the project area
- More than 51,000 GPS-tagged radiometric measurement points collected
- Approximately 283 km of ground traverses completed
- 86 rock chip samples submitted to ALS Geochemistry, an ISO/IEC 17025:2017 accredited laboratory, for multi-element assay
Radiometric Results Well Above Background
Ground radiometric surveying using a handheld RS-125 gamma-ray spectrometer confirmed the presence and intensity of numerous airborne anomalies. Against a typical host-rock background of 500–800 counts per second (cps), corridor-scale elevated zones commonly returned 1,300–2,700 cps, with multiple stations exceeding 3,000 cps and discrete peak readings of 7,100 cps, 8,800 cps and 9,400 cps.
The distribution of these elevated responses is reported to be geologically informative rather than random. Furthermore, according to the announcement, the strongest readings are consistently localised within fractured and bleached granite, leucogranite veins and sericitic fault gouge, rather than being uniformly distributed through the host granite.
This spatial association reinforces the company's interpretation of a structurally controlled hydrothermal uranium system, consistent with observations from the earlier Phase 1 and Phase 2 drill programs.
"Our field crews systematically assessed the priority airborne anomalies and confirmed strong radiometric responses on the ground, consistently within the fractured, altered and structurally prepared settings our geological model identified. With high uranium readings from portable XRF screening, supportive petrography and 86 samples at the laboratory, we move into Phase 3 targeting with a sharper, increasingly de-risked exploration model ahead of drilling and trenching commencing in Q3," said Rohan Bone, Chief Executive Officer of Infini Resources.
pXRF Screening Adds Chemical Context
Portable XRF screening of elevated outcrops returned uranium values of up to approximately 2,800 ppm U (average of multiple readings) at a fault-gouge locality in the south-east of the property, with additional readings of approximately 500 ppm and 1,000 ppm U recorded elsewhere. Uranium at these localities is reported to be associated with arsenic, lead and copper pathfinder elements, a pattern the company associates with hydrothermal uranium systems.
Petrographic analysis of representative altered granite samples has independently confirmed the fracture-controlled sericite-chlorite-epidote-hematite alteration assemblage observed in the field, with follow-up SEM-EDS mineralogical work now underway.
The company has cautioned that pXRF readings are semi-quantitative screening tools only and are not a substitute for laboratory assay results. All 86 samples have been submitted for formal laboratory analysis, with results expected in Q3 CY2026, subject to any changes in laboratory processing schedules.
Understanding Counts Per Second and Why It Matters to Investors
What Is cps (Counts Per Second)?
A gamma-ray spectrometer measures naturally occurring radiation emitted from rocks. Counts per second is the raw output of that measurement, representing how many radiation events the instrument detects every second. Higher cps indicates more radioactivity being emitted from a rock surface.
Why Does This Matter to Exploration Targeting?
In uranium exploration, elevated cps readings serve as a rapid, low-cost screening tool to flag areas where radioactivity is anomalously high relative to background levels. A reading of 9,400 cps against a background of 500–800 cps represents more than ten times the background level, which the company considers a signal worth investigating further with follow-up sampling.
What Is the Key Limitation?
Total-count cps readings measure combined gamma radiation from uranium, thorium and potassium decay series and cannot be attributed to uranium alone. They are not a measure of uranium grade. According to the announcement, these readings are used solely as an exploration targeting guide that directs where to collect samples for laboratory assay. The 86 samples now with the laboratory will provide the formal chemical confirmation of what element is driving the elevated responses.
| Term | Definition |
|---|---|
| cps (counts per second) | Raw output of a gamma-ray spectrometer; higher readings indicate more radioactivity |
| pXRF | Portable X-ray fluorescence; a rapid on-site chemical screening tool |
| ppm U | Parts per million uranium; a measure of uranium concentration |
| Fault gouge | Fine-grained material produced by grinding along a fault plane, often a fluid pathway and alteration host |
| Hydrothermal alteration | Chemical changes to rock caused by hot, mineralising fluids |
| SEM-EDS | Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy; a high-resolution mineralogical analysis technique |
Reynolds Lake and Reitenbach Lake: Maiden Drilling Program Completed
In Saskatchewan, Infini has completed what it describes as the first-ever diamond drilling program at the Reynolds Lake and Reitenbach Lake Uranium Projects. The program tested the company's system-scale exploration model on the eastern margin of the Athabasca Basin.
| Metric | Detail |
|---|---|
| Total drillholes completed | 16 |
| Total metres drilled | 3,314 m |
| Drill type | Heli-transportable diamond drill (NQ gauge) |
| Laboratory | Saskatchewan Research Council (ISO/IEC 17025:2017 accredited) |
| Assay results expected | Late Q3 CY2026 |
According to the announcement, drilling targeted high-priority zones where multiple mineralisation indicators converged, including electromagnetic (EM) conductors interpreted to represent graphitic or sulphide-rich horizons, magnetic lows associated with alteration and structurally disrupted basement rocks, elevated uranium geochemical anomalism from prior sampling, and structural complexity including shear zones and fault intersections.
What the Drillcore Revealed
Initial geological observations confirmed prospective basement lithologies, including paragneiss, graphitic schist, graphitic gouge and orthogneiss. In a number of holes, graphitic and structurally prepared intervals are reported to be associated with hydrothermal alteration assemblages comprising chlorite, hematite, sericite, clay and local epidote.
Bleaching, recrystallisation and quartz veining were also observed adjacent to interpreted fault zones. The company states these geological features are consistent with the principal components of its targeting model for basement-hosted uranium systems and with geological settings observed at deposits such as Eagle Point and Rabbit Lake on the eastern margin of the Athabasca Basin.
"While the high-grade Titus showing (1.90% U₃O₈) proved the presence of surface uranium on the property, our 2026 drilling has now intersected reactivated graphitic faults and hydrothermal hematite, conditions considered highly prospective for basement-hosted mineralisation on the margins of the Athabasca Basin. This significantly upgrades the project's potential scale, confirming an active structural and hydrothermal system with real depth," said Andy Yackulic, Strategic Technical Advisor.
All 16 drillhole core samples have been submitted to the Saskatchewan Research Council for multi-element analysis. The company has noted that assay results are currently expected in late Q3 CY2026, based on guidance reflecting congestion and extended turnaround times across accredited North American laboratories.
A Pipeline of Near-Term Catalysts
| Catalyst | Expected Timing |
|---|---|
| Portland Creek rock chip assay results (86 samples) | Q3 CY2026 |
| Portland Creek Phase 3 diamond drilling commences (~5,000 m) | Q3 CY2026 |
| Portland Creek trenching program commences (including Falls Lake Prospect) | Q3 CY2026 |
| Reynolds Lake and Reitenbach Lake maiden drilling assay results | Late Q3 CY2026 |
| Integration of drilling data with 80 km EM conductor network review | Post-assay receipt |
Trenching planned for the Falls Lake Prospect is a notable near-term activity. The prospect has previously reported a peak uranium-in-soil anomaly of 74,997 ppm (7.5%) U₃O₈. Trenching is designed to expose bedrock beneath shallow cover and investigate the potential bedrock source of this anomaly, running in parallel with the Phase 3 diamond drilling program.
Portfolio Context: Two Distinct Project Settings
Portland Creek
The project spans 329 km² in Newfoundland and lies within the Precambrian Long Range Complex. It hosts a 6 km zone of anomalous uranium and radon gas identified in lake sediments, soils and airborne surveys, an 800 m by 100 m high-grade soil anomaly at Falls Lake, and a southern cluster of high-grade soil samples peaking at 1,500 ppm U₃O₈, located 1.5 km from the recently completed Phase 2 drill area.
Reynolds Lake and Reitenbach Lake
The two contiguous projects cover a combined 767 km² on the eastern margin of the Athabasca Basin. An 80 km EM conductor network defines the scale of the structural system, with a 15 km by 3 km prospective corridor identified within it. The geological setting is described by the company as analogous to Eagle Point and Rabbit Lake, established uranium deposits along the same structural corridor.
Existing Resource Context
Infini also holds the Des Herbiers uranium resource, an Inferred Resource of 162 Mt at 123 ppm U₃O₈ (43.95 Mlb) classified under JORC 2012, which provides additional context for the scale of uranium exploration across the company's broader portfolio.
