Visible Uraninite Discovery Raises Stakes for Infini’s Saskatchewan Uranium Ambitions

Exploration Breakthrough at Reitenbach Lake

Infini Resources Limited (ASX – I88) has announced a significant milestone in its 2025 field programs at the Reynolds Lake and Reitenbach Lake uranium projects, located on the eastern margin of the Athabasca Basin in Saskatchewan, Canada. The standout highlight is the identification of visible uraninite mineralisation at surface at Reitenbach Lake, a discovery that marks a promising advancement for the company’s exploration efforts.

Field teams recorded scintillometer readings reaching an impressive 67,540 counts per second (cps) at the uraninite showing, indicating strong radioactive signatures. This visible uraninite, observed lining fractures within altered rock, suggests primary uranium mineralisation and provides a tangible target for future drilling. The structural control of the mineralisation offers direct vectors for exploration, elevating Reitenbach Lake to a high-priority status within Infini’s portfolio.

Widespread Anomalies at Reynolds Lake

Complementing the Reitenbach discovery, the Reynolds Lake project exhibited extensive radiometric anomalism, with 59 radioactive occurrences exceeding 1,000 cps and peak readings up to 9,700 cps. These anomalies coincide with multiple electromagnetic conductors extending over 10 kilometres and uranium-in-lake sediment anomalies, all aligned along key structural corridors such as the Needle Falls Shear Zone.

The geological setting at Reynolds Lake is highly prospective for unconformity-style uranium deposits, a globally significant deposit type known for high grades. Hydrothermal alteration minerals identified in the field further support the presence of fluid pathways conducive to uranium mineralisation. These findings validate Infini’s exploration model and reinforce the potential for discovering economically viable uranium deposits.

Comprehensive Sampling and Next Steps

Over 900 soil and rock samples were collected across both projects during the inaugural field programs, with all samples dispatched to ALS Global Laboratories for detailed geochemical analysis. The assay results, expected in the fourth quarter of 2025, will be critical in refining and prioritising drill targets. Samples exhibiting scintillometer readings above 5,000 cps will receive priority in the laboratory workflow.

Infini Resources plans to integrate these forthcoming assay results with existing geophysical and structural data to develop a robust understanding of mineralisation controls. This integrated approach aims to identify high-value targets for a potential drilling campaign in 2026, which could confirm uranium mineralisation at depth and advance the projects toward resource definition.

Strategic Positioning in the Athabasca Basin

Both Reynolds Lake and Reitenbach Lake projects lie within a geological environment analogous to some of the world’s most prolific uranium deposits, including those at Eagle Point and Rabbit Lake. The projects cover a combined footprint of 677 square kilometres and are strategically positioned along major structural zones known to host uranium mineralisation.

Infini’s CEO, Rohan Bone, emphasised the significance of these results, stating that the discoveries strongly validate the company’s exploration strategy and position Infini well for upcoming drilling activities. The company’s broader portfolio, including the ongoing Phase 2 drilling at the Portland Creek Uranium Project, underscores its commitment to advancing uranium exploration in key jurisdictions.
