Infini finds major uranium indicators in Canada’s Athabasca Basin

Infini Resources will further explore major bedrock conductors indicating shallow uranium mineralisation, which it identified using airborne geophysics at the company’s Reynolds Lake project in Canada’s renowned Athabasca Basin.

The encouraging results were obtained from a recent high-resolution airborne time-domain electromagnetic survey at Reynolds Lake, which covered 1100 line kilometres.

Infini Resources’ helicopter-borne TDEM geophysical array for its survey over the Reynolds Lake project in Canada has defined vertically dipping EM conductors at depths as shallow as 20 metres below surface.

This first modern airborne EM study on the site since the 1970s has identified significant bedrock conductors, including two more than 10 kilometres long in the southern project area.

The conductors align with magnetic lows and uranium radiometric anomalies and indicate potential for shallow, unconformity-style uranium mineralisation near the margin of the Athabasca Basin, a region recognised globally for its high-grade uranium deposits.

Interpreted by geophysicists Resource Potentials, the TDEM data reveals vertically dipping conductors at depths as shallow as 20 metres below surface. Most of the newly identified targets have not been subject to any modern exploration.

‘The identification of major EM conductors in an historically underexplored region located on the outboard edge of the Athabasca Basin is highly significant.’

Significantly, the 20m depth is shallower than typical Athabasca Basin uranium deposits such as Cameco Corporation’s Cigar Lake, 480m below surface, or McArthur River at 530m depth.

The company’s radiometric data reinforces the prospect of near-surface uranium mineralisation.

The shallow setting will help Infini’s exploration efforts, including by significantly reducing its costs.

The conductors indicate graphitic meta-pelitic rocks near the Needle Falls Shear Zone, which are critical for uranium precipitation. Those rock types originate from the transformation of clay-rich sedimentary rocks such as shales and mudstones.

Infini Resources chief executive officer Rohan Bone said: “Outcomes from the TDEM survey over the Reynolds Lake uranium project, previously untested by property-wide modern airborne survey methods, are extremely promising. The identification of major EM conductors in an historically underexplored region located on the outboard edge of the Athabasca Basin is highly significant.”

Bone said the coincidence of key geophysical markers across multiple large-scale anomalies reinforces the prospectivity for unconformity-style uranium mineralisation and the shallow potentially outcropping anomalies could be efficiently and quickly explored.

The 386-square-kilometre Reynolds Lake project straddles the Wollaston and Peter Lake geological domains, where conditions favour unconformity-type deposits.

The project is on an outcropping interface of key geological domains, and is underlain by Archean felsic gneisses and Lower Proterozoic metamorphic rocks, including graphitic schists, which favour the project hosting uranium.

Infini is advancing a systematic exploration strategy, using modern technologies to unlock the value of its Reynolds Lake prospect.

The company is integrating its TDEM results into a comprehensive desktop study combining geophysical, geochemical and mapping data to identify high-priority and walk-up targets for its next exploration phase.

The study is nearing completion and will guide an upcoming field campaign involving prospecting, rock geochemical sampling and mapping to further evaluate the project’s potential.

The shallow targets and strong geological indicators at Reynolds Lake make it a standout asset for future development. With its desktop study set to conclude, Infini Resources is poised to transition to field exploration and build on its initial encouraging results.

The Australian energy metals company is focused on Canada and Western Australia, where it is targeting uranium and lithium across a diversified portfolio of greenfield and brownfield projects.

Its keen approach and strategic asset base offer a promising path forward in a potentially accelerating uranium exploration space.
