Infini Resources nails high-grade surface uranium in Canada

Infini Resources (ASX: I88) has hit high-grade primary uraninite mineralisation, confirming a fertile uranium system at its Reitenbach Lake project near the world-class uranium-rich Athabasca Basin in Saskatchewan, Canada.
A standout high-grade rock chip assayed 1.90 per cent uraninite at the company’s Titus prospect, mirroring the results of an earlier electro-magnetic (EM) survey and providing strong validation of Infini’s exploration model.
At the company’s nearby Reynolds Lake project, a suite of rock chip and soil assays aligned with coincident EM targets and mapped shear zones from earlier fieldwork has also confirmed widespread uranium mineralisation across the project area.
The adjacent Reynolds Lake and Reitenbach Lake projects sit near the eastern margin of the Athabasca Basin in northern Saskatchewan and cover a combined 677 square kilometres of high-grade uranium exploration tenure.
Typically, in many Canadian terrains, visible mineralisation is limited by thick transported glacial cover, low-lying wetlands and lakes. Detailed geological mapping, aerial geophysics and radio metrics have, however, identified priority target areas that may host outcropping rocks containing uraninite.
The company believes its mineralisation extends well beyond the initial outcrop, with another zone identified 300 metres to the northeast of the discovery returning 988 parts per million (ppm) uraninite, alongside several other areas tied to priority one EM conductors.
Confirming high-grade uranium mineralisation at surface at the Titus Prospect, with a uraninite sample assaying 1.90% U₃O₈, is a standout result and provides clear confirmation that we are operating within a fertile uranium system.

Infini believes mineralisation at Reitenbach Lake occurs within structural corridors containing deformed orthogneiss and metasediments. These rocks are later crosscut by north-south fault systems that act as structural pathways for hydrothermal fluid flow supported by abundant graphitic conductors. This setting closely mirrors other high-grade basement-hosted uranium deposits found throughout the nearby world-class Athabasca Basin. Examples include the McArthur River and Cigar Lakes Mines.
Once phase two rock chip results land early next year, Infini plans to pull together its mapping, geochemistry and geophysics into a single integrated model to pinpoint and prioritise drill targets ahead of a potential maiden drilling campaign in early to mid-2026.
Uranium prices have varied considerably in 2025, recently trading in the mid-US$80 (A$120) per pound range. Supply remains tight, with major producers signalling limited output and several new reactors worldwide set to come online.
In a uranium market increasingly driven by supply security and long-term demand growth, Infini’s early success at Reitenbach Lake has put the company firmly on the radar. For explorers in the Athabasca Basin, proving the presence of high-grade uranium at surface is often the hardest part. Infini has now ticked that box – and the drill bit is next.
