    The completion of Phase 2 drilling at Portland Creek represents a transformational milestone for Infini Resources uranium exploration at Portland Creek, marking the successful completion of 5,310 metres drilled across 17 drillholes while simultaneously launching an advanced airborne geophysical survey. The comprehensive programme has delivered visible uranium across multiple drillholes spanning over 6 kilometres, pointing to the emergence of a district-scale uranium system.

    Phase 2 Drilling Campaign Delivers Impressive Scale and Scope

    The Phase 2 diamond drilling programme wrapped up with 5,310 metres drilled across 17 drillholes, systematically testing 8 structural, geochemical and geophysical targets along the expansive corridor. The programme achieved strong operational performance despite challenging Canadian weather conditions, with drilling teams maintaining excellent core recovery rates above 95%.

    Key highlights from the completed programme include:

    • 17 drillholes completed targeting multiple geological and geophysical anomalies
    • Visible uranium confirmed in multiple holes separated by over 1 kilometre
    • Elevated uranium values detected via portable XRF analysis across the corridor
    • Polymetallic signatures including molybdenum, zinc and copper supporting a fertile hydrothermal system
    • First batch of assay results expected within 4 weeks from commercial laboratories

    Furthermore, the drilling has systematically tested targets along a 6-kilometre corridor defined by major fault structures, uranium-in-soil anomalies, radiometric highs and airborne electromagnetic conductors. Consequently, this has provided Infini with unprecedented insight into the scale and potential of the Portland Creek system.

    Advanced Airborne Survey Launches to Map District-Scale Potential

    Parallel to completing the drilling programme, Infini has commenced a sophisticated helicopter-supported airborne geophysics campaign across Portland Creek's expanded landholding. The survey employs cutting-edge Xciteâ„¢ time-domain electromagnetic (TDEM) technology alongside high-resolution magnetic and radiometric data collection.

    Survey Specifications Details
    Total Line Kilometres 2,865 km
    Line Spacing 100 metres
    Flight Altitude 40-65 metres (terrain-dependent)
    Technology Xciteâ„¢ TDEM system
    Data Types TDEM, magnetics, radiometrics
    Expected Completion Q1 CY2026

    The Xciteâ„¢ TDEM system represents next-generation geophysical technology, utilising a patented inflatable 20-metre diameter transmitter loop suspended 30 metres below the helicopter. This state-of-the-art system delivers improved signal clarity and programmable waveforms with fast turn-off times. Moreover, it enables detection of both shallow and deep subsurface features critical to understanding uranium systems.

    Understanding Time-Domain Electromagnetics: A Game-Changer for Uranium Exploration

    Time-domain electromagnetics (TDEM) represents one of the most powerful geophysical methods for uranium exploration, particularly in structurally controlled systems like Portland Creek. The technology works by transmitting electromagnetic pulses into the ground and measuring the decay of induced currents in conductive materials.

    Why TDEM Matters for Investors:

    • Deep penetration capability reveals structures and alteration zones not visible from surface
    • High resolution mapping of fault systems that typically host uranium mineralisation
    • Conductive corridor identification helps trace mineralised systems across large distances
    • Integration with drilling data provides 3D understanding of the entire system

    The Xciteâ„¢ system's advanced capabilities mean Infini can map subsurface features with unprecedented detail. In addition, this directly informs future drilling strategies and target prioritisation. This technical advantage translates to more efficient exploration spending and higher probability drill targeting.

    Polymetallic System Signatures Point to Large-Scale Hydrothermal Activity

    Beyond uranium, Phase 2 drilling has revealed compelling polymetallic pathfinder elements that reinforce the interpretation of a large-scale hydrothermal system. Molybdenum, zinc and copper anomalies across several holes indicate the Infini Resources uranium exploration at Portland Creek extends well beyond uranium alone.

    Polymetallic Indicators Significance
    Molybdenum Up to 2.38% Mo detected, indicating high-temperature hydrothermal activity
    Zinc Values to 1.3% Zn suggesting extensive alteration zones
    Copper 0.15% Cu results supporting polymetallic potential
    Titanium Up to 14.4% Ti reflecting intense alteration processes

    These polymetallic signatures are particularly significant as they indicate the Portland Creek system represents more than simple uranium mineralisation. However, large-scale hydrothermal systems often host multiple economic metals, potentially expanding the project's long-term value proposition beyond uranium alone.

    CEO Commentary

    "Over 5,000 metres drilled across 17 holes has delivered visible uranium, strong alteration, and encouraging polymetallic signatures over a strike length exceeding six kilometres. This reinforces our view that Portland Creek hosts a potential district-scale uranium system with numerous targets yet to be tested," said CEO Rohan Bone.

    Strategic Timeline Sets Stage for Expanded 2026 Campaign

    The completion of Phase 2 drilling and launch of the airborne survey positions Infini for a data-rich period leading into 2026 exploration planning. The company has established a clear timeline for upcoming catalysts.

    Near-term Catalysts:

    • December 2025: First batch of drillhole assays covering holes PCDD25-007 through PCDD25-012
    • Q1 2026: Completion of airborne geophysical survey

    • 2026: Design and execution of expanded drilling campaign

    Furthermore, the integration of laboratory assay results with advanced geophysical data will provide Infini's geological team with the most comprehensive dataset ever assembled for Portland Creek. This foundation enables precision targeting for the planned 2026 expansion, potentially accelerating discovery timelines while optimising exploration expenditure.
