Vancouver, British Columbia--(Newsfile Corp. - April 29, 2025) - Nexus Uranium Corp. (CSE: NEXU) (OTCQB: GIDMF) (FSE: 3H1) ("Nexus" or the "Company") is pleased to announce it has completed its 2025 winter drill program at the Cree East Project in the Athabasca Basin, Saskatchewan. A total of seven diamond drill holes totalling 3,339 metres of NQ sized coring were completed (see Figures 1 & 2) with five holes successfully intersecting the sandstone-basement unconformity while two holes were abandoned due to technical issues.

"Our inaugural winter drill program was met with considerable success, both in refinement of our understanding of basement geology which will be crucial in subsequent drilling, and in delineating a prospective structural corridor of over 450 metres at Area B" commented Jeremy Poirier, CEO of Nexus Uranium. "With this program concluded, we await the results from chemical assays over the coming weeks as we look to plan the upcoming summer drill program next month. Cree East remains one of the most prospective uranium exploration projects within the Athabasca Basin, not only due to its relative proximity to existing infrastructure and location within the prolific Wollaston-Mudjatik trend, but due to exploration which has confirmed through drilling a number of mineralized structures with the potential to host significant uranium mineralization."

2025 Cree East Winter Drill Program

The 2025 Winter Drill Program (the "Program") was designed to expand on the previous drilling completed by CanAlaska and its Korean partners through to 2012, specifically focusing on Area B: to follow up on identified uranium enrichment and expand the understanding of structure (i.e. graphitic conductor & basement faulting), alteration, and potential mineralization controls. The Program successfully delineated the conductor, a graphitic-pelitic unit with associated alteration and structure, over a 450-metre drill-defined northeast-southwest strike length.

Highlights include hole CRE094 which intersected the graphitic conductor below the unconformity, with elevated scintillometer counts encountered from 492.2 metres down to 578.8 metres (downhole depth).

Of the seven holes drilled, five successfully intersected the sandstone-basement unconformity, with a summary of the bedrock geology encountered presented below. Please note that all reported depths are drillhole depths and the true widths are unknown.

Drillhole CRE093 intersected a broad sandstone fault zone from 370.0 - 393.0 m, characterized by strong bleaching and grey reduced alteration which was followed by strongly bleached and silicified sandstone. In the basement of CRE093 two major fault zones associated with strong alteration were intersected. The first fault zone, from 469.8 to 475.4 m is characterized by graphitic cohesive cataclastic faulting. The second fault zone, characterized by a wide interval of strongly silicified breccia from 548.5 to 574.0 m overprints a strongly chloritized pelite with intermittent short intervals of preserved cataclastic fabric. Strong bleaching, chlorite, and clay alteration extend throughout the basement and are upgraded in intensity around the fault zones.

Drillhole CRE094 intersected a broad zone of reworked hematite, limonite, and strong bleaching in medial sandstone column associated with faulting from 353.0 to 389.0 m. In the basement of CRE094, chloritized graphitic pelite was intersected from 485.0 to 526.0 m. Within the graphitic pelite, several faulted intervals exhibit elevated radiometry with a peak of 300 CPS occurring in a chlorite/carbonate/pyrite cohesive breccia at 505.1 m. Below the graphitic pelite, chloritized pelite continues with several carbonate/pyrite/chlorite breccias containing elevated radiometry up to 250 CPS and up to 25% chalcopyrite.

Drillhole CRE095 intersected a fault zone that straddles the unconformity. Within the sandstone, from 449.2 to the unconformity at 452.0 m, the fault is a cohesive milled breccia consisting of large clasts of quartz and sandstone suspended within a chlorite matrix. The fault extends to 454.7 m in the basement and consists of decimetre-scale intervals of friable cataclastic faulting with chlorite-rich matrix and clasts of chlorite-altered basement.

Drillhole CRE096 is interpreted to have overshot the conductive target and intersected footwall basement stratigraphy.

Drillhole CRE098 intersected a broad sandstone fault zone from 339.0 to the unconformity at 510.0 metres. The fault zone is characterized by broken, blocky, and faulted sandstone with re-activated clay gouge, chaotic breccias, rotated bedding, and localized intervals of desilicification and core loss (Figure 3). Throughout the fault zone, the sandstone is strongly bleached and silicified with increasing medium to dark grey sooty pyrite alteration increasing in concentration with proximity to the unconformity. The basement of CRE098 was characterized by a quartz breccia with clasts of quartz and clasts of fine grained hematized and chloritized metasediments.

Drillholes CRE092 and CRE097 were lost before intersecting the target depth due to technical issues.

Geochemical Assay Sampling

All drill core samples from the program were shipped to the Saskatchewan Research Council Geoanalytical Laboratories (SRC) in Saskatoon, Saskatchewan in secure containment for preparation, processing, and multi-element analysis by ICP-MS and ICP-OES using total (HF:NHO3:HClO4) and partial digestion (HNO3:HCl), boron by fusion, and U3O8 wt% assay by ICP-OES using higher grade standards. Sample intervals are chosen based on downhole probing logs and scintillometer (CT007-M) peaks. Assay sample intervals comprise 0.25 - 0.8 metre continuous half-core split samples over the mineralized intervals. With all assay samples, one half of the split sample is retained and the other sent to the SRC for analysis. The SRC is an ISO/IEC 17025/2005 and Standards Council of Canada certified analytical laboratory. Blanks, standard reference materials, and repeats are inserted into the sample stream at regular intervals by field staff and the SRC in accordance with quality assurance/quality control (QA/QC) procedures. Geochemical assay data, when presented, will be subject to verification procedures by qualified persons prior to disclosure.

The Company cautions that radioactivity is total gamma from drill core measured with a CT007-M gamma-ray spectrometer/scintillometer in cps (counts per second). Measurements of total gamma cps on drill core are an indication of the presence of radioactive materials (uranium, thorium, and/or potassium), but may not directly correlate with uranium chemical assays. Total gamma cps readings are preliminary and may not be used directly to quantify or qualify uranium concentrations of the rock samples measured. The Company considers all CT007-M readings greater than 100 cps to constitute elevated radioactivity.
