Infini Resources Launches Maiden Drilling at Saskatchewan Uranium Projects

Maiden Drill Program Underway at Reynolds and Reitenbach Lake

Infini Resources Limited (ASX:I88) has initiated its first-ever diamond drilling campaign at the Reynolds Lake and Reitenbach Lake uranium projects in northern Saskatchewan, Canada. The program marks a significant step from target generation to active testing of a potential uranium system that remains largely untested by drilling.

The campaign plans a minimum of 2,500 metres across at least 12 drillholes, focusing on high-priority targets defined by the convergence of electromagnetic (EM) conductors, structural complexity, and uranium geochemical anomalies. Notably, the Titus Prospect, which has surface uranium mineralisation grading up to 1.90% U₃O₈, is a key target within this corridor.

The projects collectively span 766 square kilometres on the eastern outboard margin of the Athabasca Basin, a region globally renowned for high-grade uranium deposits. The exploration model integrates approximately 80 kilometres of EM conductors and a continuous 15 km by 3 km prospective corridor where mineralisation vectors coincide. This approach aims to systematically test the structural corridors and basement rocks that may host unconformity-related uranium mineralisation.

Strategic Location and Geological Setting

Reynolds and Reitenbach Lake lie along the Needle Falls Shear Zone, a major crustal-scale structure separating distinct geological domains. The area features Archean to Paleoproterozoic metamorphic and igneous rocks, with graphitic schists and gneisses identified, lithologies known to host uranium mineralisation in the Athabasca Basin. Recent surface sampling and petrographic analysis have confirmed uranium mineralisation and hydrothermal alteration consistent with unconformity-related systems.

The setting is considered analogous to established uranium deposits such as Eagle Point and Rabbit Lake, where mineralisation occurs along graphitic shear zones at domain boundaries. Infini’s CEO, Rohan Bone, who is currently on-site in Saskatchewan, emphasised the projects’ compelling nature, highlighting the combination of high-grade surface mineralisation, extensive EM conductors, and structural complexity as a strong foundation for exploration success.

Operational Readiness and Contractor Mobilisation

Experienced Canadian contractors Archer Cathro and Rodren Drilling have been mobilised to execute the drilling program, which is designed with flexibility to scale based on initial results. The company aims to provide ongoing updates as drilling progresses, signalling confidence in the potential of these underexplored uranium corridors.

This development follows Infini Resources securing drill permits and finalising targets in recent weeks, confirming the company’s methodical advancement toward unlocking the resource potential of these projects. The campaign complements Infini’s broader Canadian portfolio, including the Portland Creek Uranium Project in Newfoundland, where an airborne EM and magnetics survey is currently underway.

Portland Creek Survey and Assay Delays

While the Saskatchewan drilling program has commenced, Infini has reported delays to the airborne geophysical survey and Phase 2 assay results at Portland Creek due to adverse weather and extended laboratory turnaround times. The airborne survey is now expected to complete in May 2026, with assay results also anticipated in May. The company does not foresee these delays materially impacting its overall exploration timeline or the planned Phase 3 drilling campaign later in the year.

These developments underscore the challenges of operating in remote, weather-sensitive jurisdictions but maintain the integrity of Infini’s exploration schedule. The integration of all datasets from Portland Creek will support future targeting and drilling decisions.

With the maiden drilling now underway at Reynolds and Reitenbach Lake, and geophysical programs progressing at Portland Creek, Infini Resources is positioning itself to advance multiple uranium projects across Tier-1 Canadian jurisdictions in 2026.

Investors and observers will be keen to see the initial assay results from these drillholes, which will be critical in determining the scale and economic potential of the uranium mineralisation in this underexplored corridor.

These efforts build on the company’s broader strategy to leverage its diversified uranium and lithium portfolio, including the recently highlighted district-scale mineralisation at Portland Creek and the inferred resource at Des Herbiers in Western Australia.

As Infini moves from exploration into drilling, the coming months will be pivotal in defining the next chapter for its Canadian uranium assets.
