Infini Resources flags widespread uranium at Portland Creek; shares rocket 185% on pXRF hits

Key highlights

• Extensive downhole uranium indicated by spot pXRF across 28–312m in hole PCDD25-012, with uraninite observed along fractures at 270m (≈1.2% U) and 289m (≈1.17% U). 
• High-grade molybdenum also logged: 2.38% Mo in a 4m albitised interval (PCDD25-009A). Titanium to 14.4% Ti (PCDD25-008) evidences a polymetallic hydrothermal system. 
• Program has only partially tested 2 of 12 priority targets within a >6 km corridor of strong uranium-in-soil anomalies (to 74,997 ppm U₃O₈); assays due Q4 CY2025. 
• Caution: pXRF readings are indicative only and not a substitute for laboratory assays; samples dispatched to ALS for analysis. 
• Market reaction (ASX delayed, 3:22 pm AEDT, 9 Oct 2025): I88 A$0.655, +184.78%; volume 16.28m; market cap ~A$45m; 52-week range A$0.078–0.720. 
  
   

Infini Resources (ASX: I88) electrified the market on Thursday, 9 October 2025, after unveiling widespread, fracture-hosted uranium indicated by handheld pXRF across a long downhole interval at its 100%-owned Portland Creek Uranium Project in Newfoundland, Canada. The stock surged ~185% intraday as investors digested visuals and descriptive core logs showing uraninite on joint and fracture surfaces in hole PCDD25-012, supported by elevated uranium readings from near-surface down to ~312m. 

What Infini found—and where

The standout is PCDD25-012 (Target 2), where the company reports peak pXRF uranium values up to 12,000 ppm U (≈1.2% U) at 270m and 11,700 ppm U (≈1.17% U) at 289m, coincident with visible uraninite along fractures. Across ~28–312m, more than 90% of ~50 pXRF spot checks along a dominant near-vertical fracture set reportedly returned 1,000–12,000 ppm U, within intensely altered granites exhibiting albite, hematite, chlorite/sericite and brecciation. Infini interprets these structures as principal fluid pathways that focused uranium-bearing hydrothermal fluids. 

Importantly, PCDD25-012 is ~1.5 km from a peak soil anomaly of 74,997 ppm U₃O₈, one of multiple high-order surface anomalies strung along E–W faults within a >6 km corridor. The company argues that this spatial relationship—fracture-controlled uranium at depth, aligned to surface geochem—supports the potential for a district-scale system. 

Not just uranium: a polymetallic signature emerges

While uranium headlines the release, the Phase 2 program has delivered polymetallic pathfinders that strengthen the hydrothermal model. At Target 1, hole PCDD25-009A returned a spot 2.38% Mo (pXRF) inside a 4m zone of intensely albitised granite, accompanied by Pb-Zn-Cu-Ti pathfinders—evidence of a magmatic-hydrothermal input. Nearby PCDD25-008 intersected sulphide-rich zones and a cavity with 14.4% Ti alongside elevated V-Nb-Cu-Zn. At Target 2, PCDD25-010 showed 1,200 ppm U (39.5m) and 0.28% Mo (80m) on pXRF, while down-dip PCDD25-011A indicated continuity of the altered, fractured corridor with near-surface uranium spot readings to 600 ppm. Taken together, the company says the E–W and NE-trending corridors act as major fluid conduits. 

CEO commentary 

“These first drillholes are a game-changer for Portland Creek. We have intersected extensive zones of elevated uranium, confirming widespread hydrothermal alteration and validating our exploration model. With Phase 2 drilling still in the early stages, the scale of the opportunity at Portland Creek is becoming increasingly clear. With every hole, we are uncovering more indications of a potential district-level polymetallic uranium system in Newfoundland, at a time when uranium and critical minerals are central to the global energy transition.” — Rohan Bone, CEO. 

Where the program stands—and what’s next

By the date of the announcement, Infini had six holes completed or in progress (PCDD25-007/008/009A/010/011A/012) for a combined ~1,421m drilled—only partially testing 2 of 12 priority targets defined by soils, radiometrics and structures. All core is logged, photographed and sampled, with dispatch to ALS Global for geochemical assays. The company expects assay results in Q4 CY2025, and says planning is underway to expand the minimum 2,500m Phase 2 program to more efficiently test the highest-priority uranium targets along the corridor. 

Operationally, Infini will continue drilling at Target 2 (where PCDD25-012 sits), test additional E–W fault blocks and incorporate systematic sampling + structural analysis to vector toward high-grade zones. The proximity to the historic Daniel’s Harbour zinc mine (~10 km) is cited as an analogue for large-scale hydrothermal activity in the district, albeit with different metal endowment. 

A necessary caveat: pXRF is not a resource

Infini is explicit that portable XRF results are qualitative spot measurements—useful for real-time vectors, but not equivalent to laboratory assays and not suitable for resource estimation. Variables such as sample heterogeneity, surface effects and small analysis windows can skew readings; definitive grades will be reported once lab assays are returned. Until then, the scope, thickness and continuity of mineralisation remain unconfirmed. (For transparency, the release includes pXRF QA/QC notes and JORC Table 1.)

Why the market cared

Thursday’s share-price reaction—I88 +184.78% to A$0.655 (ASX delayed, 3:22 pm AEDT), on 16.28m shares traded—reflects the step-change nature of the geological evidence: visible uraninite and long runs of elevated uranium spots in fresh structures beneath very strong surface anomalies. The market also gravitated to the scale narrative—only 2 of 12 targets tested—and the polymetallic fingerprints (Mo, Ti, base-metal pathfinders) that often accompany robust hydrothermal systems. Still, professional investors will watch for assay confirmation, true-widths, and whether follow-up holes begin to connect the dots into coherent zones suitable for resource drilling. (Company snapshot: market cap ~A$45m, 68.67m shares, 52-week A$0.078–0.720.) 

What to watch from here

• Assay timing and reconciliation: Lab results in Q4 CY2025 will test how closely pXRF and scintillometer indicators convert to grade and continuity. 
• Follow-up drilling at Target 2: Step-outs along the dominant fracture set and down-dip probing for thicker, better-connected mineralised zones. 
• Expansion across the corridor: Prioritising the remaining 10 targets in the >6 km anomaly trend, where structural intersections and alteration halos may repeat. 
• System scale: Additional Mo-Ti-V-Nb pathfinder responses could refine vectors and bolster the district-scale thesis Infini is advancing. 
  
   

Takeaway

Infini’s Phase 2 work has moved Portland Creek from concept to compelling drill evidence: uraninite in core, long runs of elevated uranium spots, and polymetallic signatures within intensely altered granites along major faults. The geological plumbing looks real; whether it knits into economic widths and grades is the next question—one only lab assays and systematic step-out drilling can answer. For now, the risk/reward has shifted: exploration risk remains high, but so too has the scale potential if subsequent holes begin to define continuity across multiple targets.
