Infini’s First Drilling at Athabasca Margin Could Make or Break Uranium Ambitions

Exploration Milestone for Infini Resources

Infini Resources Limited (ASX:I88) has reached a pivotal stage in its uranium exploration journey with the finalisation of maiden drill targets at its Reynolds Lake and Reitenbach Lake projects in northern Saskatchewan, Canada. Scheduled to commence in the second quarter of 2026, the upcoming diamond drilling campaign aims to systematically test a series of high-priority uranium targets identified through a comprehensive integration of geophysical, geochemical, and structural data.

This drilling program represents the first-ever test of this underexplored area on the eastern margin of the Athabasca Basin, a region renowned worldwide for its high-grade uranium deposits. The projects cover a substantial footprint of 766 square kilometres and are strategically positioned along major structural corridors that have been interpreted as prospective pathways for uranium mineralisation.

Compelling Targets Backed by High-Grade Surface Mineralisation

A key highlight underpinning the drilling campaign is the discovery of high-grade uranium mineralisation at the Titus Prospect, where rock chip samples have returned assays as high as 1.90% U3O8. This discovery sits along a priority electromagnetic (EM) conductor and a structurally complex corridor, validating the company’s exploration model and targeting approach.

Infini’s technical team has meticulously integrated airborne electromagnetic and magnetic surveys flown in 2025 with detailed soil geochemistry and structural mapping. This multi-disciplinary approach has delineated approximately 80 kilometres of EM conductors and a continuous 15-kilometre by 3-kilometre prospective corridor adjacent to Titus, highlighting a system-scale footprint with strong potential for basement-hosted and unconformity-related uranium mineralisation.

Strategic Drilling Program Designed for Flexibility and Efficiency

The maiden drilling program will comprise approximately 12 to 16 diamond drillholes, averaging around 220 metres in depth, totalling a minimum of 2,500 metres. The program is designed with flexibility to adjust drillhole locations and pursue follow-up drilling based on real-time core logging and gamma probe results, enabling the company to efficiently evaluate key target areas.

Infini’s CEO, Rohan Bone, emphasised the significance of this milestone: "The integration of geophysics, geochemistry, and structural interpretation has defined a number of compelling, high-priority targets across a large, prospective uranium system. The presence of high-grade uranium at surface at the Titus Prospect, combined with the scale of the EM conductor network and associated alteration footprint, provides strong encouragement that we are vectoring into a potentially significant mineralised system."

Community Engagement and Regulatory Progress

As part of its responsible exploration strategy, Infini is actively engaging with First Nations groups, including the Ya’thi Néné Lands and Resources, to ensure alignment with community interests and support permitting processes. Key contractors, Archer Cathro for geological services and Rodren Drilling for drilling operations, have been appointed, with mobilisation planned for mid-April 2026.

Permitting and regulatory approvals are advancing to facilitate the commencement of drilling activities, marking a critical step toward unlocking the uranium potential of this strategically located landholding.

Positioning in a Globally Significant Uranium Province

The Reynolds Lake and Reitenbach Lake projects lie on the eastern outboard margin of the Athabasca Basin, an area synonymous with some of the world’s highest-grade uranium deposits. The geological setting is analogous to established uranium systems such as Eagle Point and Rabbit Lake, where mineralisation occurs along graphitic shear zones at the boundary between metasedimentary and granitoid basement rocks.

Infini’s exploration model targets these structurally complex zones, where multiple vectors including EM conductors, magnetic lows, uranium geochemical anomalies, and interpreted structural corridors converge, offering a coherent and promising framework for discovery.
