Fission Uranium Corp.  announced completion of the winter 2024 exploration drill program at its PLS high-grade uranium project, in the Athabasca Basin region of Saskatchewan, Canada. A total of 15 holes (~5,567m) were completed on six separate target areas. The target areas were located along strike to the east (East Extension) and to the west (Bridle & Saddle) of the Triple R deposit as well as parallel shear structures located to the north (Holster and Pistol) as well as to the south (Saloon) of Triple R. Drilling encountered highly prospective features considered essential to the presence of high-grade uranium mineralization such as favorable lithology, large-scale hydrothermal alteration, graphitic shear zones and in some cases elevated radioactivity on the various target areas.

Based on the results of the winter program, multiple target areas on the PLS Corridor will be prioritized for follow up drilling in subsequent programs. Drilling Highlights: Winter exploration drilling complete with multiple holes intersecting anomalous radioactivity in association with hydrothermal alteration and favorable lithostratigraphic and structural features: Both holes at the Saloon target were deemed highly prospective particularly considering they are west along trend of the recent "PCE" high-grade discovery; All 7 holes at the Far East target hit anomalous features considered prospective and proximal to the presence of nearby uranium mineralization, including 4 holes with anomalous radioactivity; Highly prospective geology was encountered at the Pistol and Saddle target areas. Saloon Target (Holes PLS24-638 and PLS24-641 for a total of 1,021m): Both holes hit anomalous radioactivity in strongly altered (clay, chlorite, hematite, graphite, silica) structural deformation zones. Anomalous radioactivity and alteration at Saloon has now been identified over 50m in the down-dip direction and 220m along strike, suggesting a major hydrothermal fluid pathway which contains uranium mineralization.

The Saloon shear zone is on trend to the west with the recent high-grade "PCE" discovery (hole RK-24-183) reported at NexGen's SW2 property. Drill results demonstrate the Saloon target is highly prospective and warrants follow up. East Extension Target (Holes PLS24-639, PLS24-640, PLS24-644, PLS24-646/646A, PLS24-647 and PLS24-648) for a total of 1,310m): All seven holes hit anomalous radioactivity up to +490 cps in the same graphitic shear zone, the "main shear zone", that hosts the Triple R pods to the west.

There is pervasive strong clay alteration and structural deformation in the Far East holes. Drill results demonstrate the East Extension target is highly prospective and warrants follow up. Pistol Target (Holes PLS24-642 and PLS24-650 for a total of 1,711m): PLS24-642 intersected potentially the same hanging wall stratigraphy as the nearby Arrow deposit, and hosted zones of wet rock alteration, dravite breccia and rose quartz, all of which are reported to have a close spatial relationship to uranium mineralization at Arrow.

A series of graphitic shear zones, which are likely an extension of the same host rocks as Arrow was intersected below the previously noted features. No uranium mineralization was intersected in this hole but results nevertheless contain very positive signs. PLS24-650 was drilled 340m northeast along trend and intersected a wide zone of wet rock style alteration starting at 339m with potential rose quartz but no dravite or graphitic shear zones.

Drill results demonstrate the Pistol target is highly prospective and warrants follow up. Saddle Target (Hole PLS24-649 for a total of 365m): Located west along trend of the Triple R high-grade pods, PLS24-649 hit a silicified hanging wall, underlain by a thick sequence of graphite, chlorite, clay and hematite altered gneissic rocks, which are equivalents to the Triple R host rocks (i.e., same stratigraphy and similar alteration as Triple R host rocks). This is significant as it is the first time that drilling has intercepted the same rocks and alteration as Triple R west of the R1515W zone.

Drill results demonstrate the Saddle target is highly prospective and warrants follow up. Holster Target (Hole PLS24-637 for a total of 609m): The drillhole intersected a thick sequence of variably silicified, clay, chlorite and sericite altered quartz-feldspar-biotite-garnet gneiss and dioritic gneiss, with local sections of abundant semi-massive to massive sulphide minerals. A 0.5m lens of elevated radioactivity was intersected at 95m in pervasively chlorite altered gneissic rocks, returning up to 320 cps but is suspected to be due to thorium, rather than uranium.

Bridle Target (Holes PLS24-643 and PLS24-645 for a total of 552m): PLS24-643 and PLS24-645 tested the PLV-3A EM conductor approximately 1km and 1.6km west of R1515W respectively, along the same EM conductor that hosts the Triple R deposit s where interpreted faults identified from resistivity crosscut the conductor. Both of the drillholes intersected variably chlorite, silica and hematite altered quartz-feldspar-biotite-garnet gneiss and mafic rocks throughout their length. A graphitic, strongly deformed fault zone was intersected in PLS24-643, no similar fault zone was intersected in PLS24-645.

Natural gamma radiation that is reported in this news release was measured in counts per second (cps) using a Mount Sopris 2GHF-1000 Triple Gamma probe, which allows for accurate measurements in high grade mineralized zones. The reader is cautioned that gamma probe readings are not directly or uniformly related to uranium grades of the rock sample measured, and should be used only as a preliminary indication of the presence of radioactive materials. In addition, natural gamma radiation was measured in counts per second (cps) using a hand-held RS-125 Scintillometer, manufactured by Radiation Solutions, which is capable of discriminating readings up to 65,535 cps. All intersections are down-hole depths.

All depths reported of core interval measurements including radioactivity and mineralization intervals widths are not always representative of true thickness.  Samples from the drill core will be split in half sections on site and where possible, samples will be standardized at 0.5m down-hole intervals. One-half of the split sample will be sent to SRC Geoanalytical Laboratories (an SCC ISO/IEC 17025: 2005 Accredited Facility) in Saskatoon, SK for analysis which includes U3O8 (wt %) and fire assay for gold, and includes a 63 element ICP-OES analysis and boron. The other half of the split core remains on site for reference.
