Nexus Uranium Intersects Uranium Mineralization at Cree East in Unconformity Test from Winter Drill Program

Rhea-AI Summary

Nexus Uranium (OTCQB: GIDMF) has reported assay results from its 2025 winter drill program at the Cree East Project in Saskatchewan's Athabasca Basin. The program's key achievement was identifying a 450-metre-long prospective structural corridor within Area B, with one of five unconformity drill tests intersecting uranium mineralization.

Drill hole CRE094 revealed multiple uranium intersections, with the highest grade being 0.066% U₃O₈ over 0.3m. The program also detected elevated levels of pathfinder elements including copper, nickel, cobalt, and thorium, indicating a potentially fertile mineralizing system. All samples were analyzed at the Saskatchewan Research Council Geoanalytical Laboratories following strict QA/QC protocols.

Positive

• None.

Negative

• Only one out of five drill tests intersected uranium mineralization
• Relatively low-grade uranium intersections (highest 0.066% U₃O₈)
• True widths of mineralization zones currently unknown

Vancouver, British Columbia--(Newsfile Corp. - July 16, 2025) - Nexus Uranium Corp. (CSE: NEXU) (OTCQB: GIDMF) (FSE: 3H1) ("Nexus" or the "Company") is pleased to report assay results from its 2025 winter drill program at the Cree East Project in the Athabasca Basin, Saskatchewan. The program comprised five unconformity drill tests, one of which intersected uranium mineralization. A key outcome of the program was the delineation of a 450-metre-long prospective structural corridor within Area B.

Highlights from CRE094:

• 0.066% U₃O₈ over 0.3 m from 578.50 m
• 0.052% U₃O₈ over 0.3 m from 504.90 m
• 0.044% U₃O₈ over 0.3 m from 539.10 m
• 0.041% U₃O₈ over 0.5 m from 527.60 m

The reported intervals are intercept lengths, the true widths are unknown

"The results from our winter drill program continue to validate the potential of the Cree East Project. Intersecting uranium mineralization in one hole and identifying a structural corridor over 450 metres is a significant step forward," commented Jeremy Poirier, CEO of Nexus Uranium. "The presence of pathfinder elements such as copper, nickel, and cobalt alongside uranium strengthens our confidence that we are within a highly prospective mineralized system. These results set the stage for focused follow-up work to target higher-grade zones and advance toward a potential discovery."

2025 Cree East Winter Drill Program

The 2025 Winter Drill Program (the "Program") was designed to build on historical drilling by CanAlaska and its Korean partners (2008-2012), with a specific focus on Area B. The objective was to follow up on previously identified uranium enrichment and enhance the understanding of basement structure (including graphitic conductors and faulting), alteration patterns, and mineralization controls. The Program successfully delineated a graphitic-pelitic conductor unit characterized by structural features indicative of post-Athabasca reactivation, associated hydrothermal alteration, and elevated radioactivity.

In addition to uranium mineralization, the drill program returned elevated concentrations of several other metals, including copper (Cu), lead (Pb), zinc (Zn), nickel (Ni), molybdenum (Mo), cobalt (Co), thorium (Th), and vanadium (V). These elements were spatially associated with the uranium-enriched intervals and are considered significant from a geochemical and exploration standpoint.

Elevated levels of these metals-often referred to as pathfinder elements-are commonly associated with the hydrothermal systems that control uranium deposition in the Athabasca Basin. Their co-occurrence with uranium, particularly within structurally complex and altered zones, is a strong indicator of a fertile mineralizing system. For example:

• Nickel and cobalt are typically found in reductive, graphitic basement rocks where uranium often precipitates.
• Copper and lead may reflect the presence of sulphide-rich hydrothermal fluids capable of transporting uranium.
• Thorium and vanadium are frequently associated with alteration halos peripheral to uranium mineralization.
• Molybdenum is sensitive to changes in redox conditions, its presence can be indicative of conditions under which uranium mineralization is formed

The presence and distribution of these pathfinder elements strengthen the geological model and provide valuable vectoring tools for identifying and targeting potential zones of higher-grade uranium in future exploration campaigns.

Sampling and Analytical Protocols

Drill core sampling for the 2025 Winter Program followed CanAlaska's established protocol, which classifies samples as either systematic or spot based on geological context and analytical needs.

• Systematic samples are composite in nature and are used to characterize broader geological intervals. These consist of 1-2 cm disks of whole core collected at the start of each row of core in the core box over 9 to 20 metre intervals. The collected core fragments are composited into a single sample for pathfinder element analysis.
• Spot samples are targeted and collected from discrete geological features requiring higher-resolution geochemical analysis. These comprise 0.25-0.5 metre continuous half-core splits taken from mineralized intervals or zones of interest.

All core samples were securely transported to the Saskatchewan Research Council (SRC) Geoanalytical Laboratories in Saskatoon for preparation and analysis. The SRC, an ISO/IEC 17025/2005 and Standards Council of Canada accredited facility, conducted multi-element geochemical analysis using:

• ICP-MS and ICP-OES (total digestion: HF:HNO₃:HClO₄; partial digestion: HNO₃:HCl),
• Boron by fusion, and
• U₃O₈ wt% by ICP-OES using higher-grade reference standards.

Sample intervals were selected based on geological logging, scintillometer (CT007-M) readings, and downhole probe results. One half of each split spot sample was retained for reference, with the other sent for analysis. Quality control measures included routine insertion of blanks, standards, and duplicates both by field crews and SRC, in line with best practices for QA/QC. All assay data are subject to independent verification by qualified persons prior to disclosure.

The Company notes that total gamma measurements are derived from CT007-M handheld scintillometer readings and reported in counts per second (cps). These measurements are preliminary and indicate the presence of radioactive elements such as uranium, thorium, and/or potassium, but do not directly quantify uranium content. Values above 100 cps are considered elevated; however, only laboratory assays can confirm uranium concentrations.
