Infini Resources Discovers Multiple Uranium-Bearing Zones Across District-Scale System at Portland Creek

Infini Resources Portland Creek discoveries have marked a significant breakthrough in uranium exploration, with multiple uranium-bearing zones now encountered across drill holes separated by over a kilometre. The Phase 2 drilling programme has expanded beyond its original scope, with 3,910 metres drilled to date across multiple high-priority targets within a 6-kilometre corridor of uranium anomalies.

The latest results demonstrate the emerging potential for a district-scale, structurally-controlled uranium system, with visible uranium minerals and elevated readings intersected across several widely spaced targets. This includes uraninite-bearing fractures with portable XRF readings reaching 5,500 ppm U in PCDD25-019 and 6,600 ppm U in PCDD25-014, combined with the previously reported high-grade uranium in PCDD25-012 of up to 1.20% U.

Key highlights include:

  • Visible uranium detected across multiple drill holes over 1km apart
  • Peak portable XRF readings of 5,500 ppm U and 6,600 ppm U
  • Evidence of polymetallic system with zinc, copper, and molybdenum enrichment
  • 3,910m drilled across 5 of 12 priority targets
  • Planning underway for airborne geophysical survey in Q4 2025/Q1 2026

CEO Commentary
"The Phase 2 drilling programme at Portland Creek continues to surpass our expectations. We are now seeing visible uranium and elevated U readings across multiple targets over a kilometre apart, demonstrating the potential scale of this emerging district," said CEO Rohan Bone.

Portland Creek Emerging as District-Scale Uranium System

The Phase 2 drilling programme has systematically tested structural, geochemical and geophysical anomalies within the 6-kilometre corridor. Furthermore, drilling has now intersected visible uranium minerals across several targets separated by kilometres. This provides compelling evidence for a potential district-scale, structurally-controlled uranium system.

Recent drilling highlights:

Drill Hole Location (UTM E, N) Depth (m) pXRF Reading Description
PCDD25-019 470813E, 5558967N 16m, 42m, 215m Up to 5,500 ppm U Uraninite in fractures
PCDD25-016 470515E, 5558036N 139-151m, 407m Up to 4,000 ppm U Multiple fracture zones
PCDD25-014 470462E, 5558025N 28m 4,700 ppm U Brecciated interval
PCDD25-012 470459E, 5557965N Various Up to 12,000 ppm U Multiple intervals

The widespread uranium mineralisation at shallow depths strongly supports the interpretation of a large, structurally controlled uranium system. Moreover, these mineralised zones occur within structurally distinct corridors separated by more than 1km. Consequently, this indicates uranium-bearing fluids have circulated throughout a broad, multi-kilometre system.

Understanding Structurally-Controlled Uranium Systems

What are structurally-controlled uranium deposits?

Structurally-controlled uranium deposits form when uranium-bearing fluids move through fault systems and fractures in the Earth's crust. These systems can extend over large distances, creating multiple zones of mineralisation along structural corridors. The uranium is typically deposited when the fluids encounter changes in chemistry, temperature, or pressure within the fracture network.

Why this matters to investors

This deposit type is significant because structurally-controlled systems can host substantial uranium resources over extensive areas. The discovery of mineralisation across multiple widely-spaced drill holes suggests that Infini Resources Portland Creek discoveries may represent a large-scale system. In addition, this indicates district-wide potential rather than isolated small occurrences.

Polymetallic System Potential Adds Value

Beyond uranium, the drilling programme continues to reveal a polymetallic hydrothermal system with multiple metals detected across various structural domains. This diversifies the project's potential economic value beyond uranium alone.

Multi-metal associations identified:

Element Peak Reading Location Significance
Zinc (Zn) 8,000 ppm PCDD25-019, 112m Industrial metal demand
Copper (Cu) 1,500 ppm PCDD25-019, 137m Critical for energy transition
Molybdenum (Mo) 1,800 ppm PCDD25-019, 185.5m High-value specialty metal
Uranium (U) 5,500 ppm PCDD25-019, 16m Primary target commodity

The cumulative evidence, including an earlier portable XRF reading of 2.38% Mo in a 4-metre section within PCDD25-009A, suggests Portland Creek may represent a polymetallic uranium system of considerable scale. However, this multi-metal potential could enhance the project's economics and provide additional revenue streams.

Strategic Next Steps and Timeline

Immediate priorities (Q4 2025):

  • Complete Phase 2 drilling through early December 2025
  • Receive first batch of assay results from accredited laboratories
  • Process and sample remaining drill core from holes PCDD25-013 to PCDD25-019

Medium-term developments (Q1 2026):

  • Execute high-resolution helicopter-supported airborne geophysical survey
  • Deploy magnetics, time-domain EM and radiometrics across existing and newly acquired tenements
  • Design expanded 2026 drilling campaign based on integrated results

Strategic positioning:

  • Test remaining 7 of 12 priority targets within the 6km corridor
  • Further evaluate existing and newly defined structural targets
  • Advance understanding of district-scale mineralisation controls

The planned airborne survey will provide crucial data to refine structural and lithological targeting across the expanded tenement package. Furthermore, this could potentially identify additional prospects within this emerging uranium district.

Investment Thesis: Early-Stage District Discovery

Why Portland Creek represents a compelling opportunity

Scale Potential: The discovery of uranium mineralisation across drill holes separated by over 1km within a 6km corridor of soil anomalies suggests significant scale potential. For instance, district-scale uranium systems can host world-class resources.

Shallow Mineralisation: Uranium intersections at shallow depths (from 16m) indicate potential for lower-cost mining scenarios compared to deep underground operations. Consequently, this could improve project economics significantly.

Polymetallic Upside: The presence of zinc, copper, and molybdenum alongside uranium provides additional value potential. In addition, this could improve project economics through multiple revenue streams.

Strategic Location: Newfoundland's mining-friendly jurisdiction and established infrastructure support development potential for significant discoveries.

Early-Stage Value: With only 5 of 12 priority targets tested to date, significant exploration upside remains within the defined anomalous corridor. However, this represents substantial future drilling potential.

Why Investors Should Follow Infini Resources
