Radiant Uranium Corp. announced on October 1, 2026, a two-phase exploration program for the Cross Lake property, a 2,048-hectare land package located northwest of the historic Key Lake mine in northern Saskatchewan. Phases 1 and 2, including consultation and permitting procedures, carry a combined budget of approximately C$325,000, already in hand. Diamond drilling is scheduled for the first half of 2027.
The program builds on a solid foundation. Uranium mineralization at Cross Lake is associated with garnet-rich pegmatitic gneiss along a northeast-trending structural lineament extending over 2.4 kilometres. Three mineralized zones have been identified: Narrows, Portage, and Cross. Historical work at the Narrows zone outlined mineralization with true widths ranging from 11 to 15.8 metres, with drill holes reaching depths of approximately 75 metres. According to the company, this system remains largely untested at depth.
Phase 1 will include ground radiometric surveys and limited shallow drilling to assess the surface extent of the mineralization. Phase 2 will refine priority targets ahead of diamond drilling, integrating Phase 1 results with additional geophysical surveys. Concurrently, Radiant Uranium will initiate community consultations and the permitting processes required before bringing heavy equipment on site. The approach follows a precise logistical sequence, designed to avoid committing resources to the most expensive exploration stages without first establishing an up-to-date technical picture.
CEO Clive Massey stated that the goal is to systematically build on Cross Lake’s historical evidence to generate the technical data needed to define targets for diamond drilling. The property’s historical estimate is considered significant as it demonstrates the deposit’s potential, even though it was based on criteria of the time. Converting that estimate into a mineral resource compliant with current standards will require confirmation drilling and infill holes at previously tested locations — and that is precisely what the two preparatory phases are designed to deliver.
Cross Lake is part of a broader portfolio that also includes the Key Lake Road and Gorilla Lake projects, all located within the Athabasca Basin, one of the world’s most geologically prolific uranium districts. The Basin hosts some of the highest-grade uranium mines on the planet, and proximity to existing infrastructure helps junior companies like Radiant Uranium keep logistical costs in check. With both phases funded and a clear timeline in place, the Canadian junior now has a concrete roadmap toward a potential verified resource. The 2027 drilling campaign will determine whether the historical data holds up under modern exploration methods.
