100% hit rate for nineteen-hole program on the R1515W zone

KELOWNA, BC , July 17, 2024 /CNW/ – FISSION URANIUM CORP. (” Fission ” or ” the Company “) is pleased to announce results from the final thirteen drill holes on the R1515W zone at its PLS property, in Canada’s Athabasca Basin region. All holes intercepted wide intervals of mineralization, with nine holes additionally hitting high-grade sections. Of particular note, PLS24-664 (line 1545W) intersected 6.74m of total composite >10,000 cps in 77.0m of total composite mineralization and PLS24-663 (line 1500W) intersected 5.79m of total composite >10,000 cps in 50.4m of total composite mineralization . The R1515W upgrade program is now complete. Results will be used to upgrade the resource classification of the zone from mostly inferred to indicated and higher, for potential inclusion in the current mine plan (see News Release April 08, 2024 ).

Ross McElroy , President and CEO for Fission, commented, “Our resource growth program has been a resounding success. Every hole is strongly mineralized with the majority intersecting high-grade intervals. With these results in hand, and once assay results quantify and qualify results, we are confident we will have achieved our goal of upgrading the majority of the R1515W zone resource classification.  After which, once upgraded, we will be able to consider including the zone in the mine plan in the future. This in turn will increase mine reserves and further enhance the production profile of the PLS project. ”

Drilling: Technical Details for the R1515W Zone and the 19-Hole Program

The R1515W zone presently contains an Indicated Resource of 67,000 tonnes at an average grade of 1.15% U ₃ O ₈ totaling 1.7 million lb. U ₃ O ₈ and an Inferred Resource of 234,000 tonnes at an average grade of 0.96% U ₃ O ₈ totaling 5 million lb. U ₃ O ₈ , using a cutoff grade of 0.25% U ₃ O ₈ . The objective of R1515W drilling was to convert areas of the R1515W zone currently classified as Inferred Resources to Indicated Resources through closely spaced drilling, potentially allowing it to be brought into the current mine plan. Drillhole pierce point spacing at the R1515W zone to upgrade the resource classification targeted ~25m by ~15m, grid north-south by grid east-west, respectively. Additionally, critical geotechnical and hydrogeological information will be collected at the R1515W zone, to be used in the assessment of viability of inclusion in the overall PLS project mine plan and schedule.

Natural gamma radiation in drill core that is reported in this news release 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.  Drill holes are systematically down-hole surveyed for natural gamma radiation, 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 scintillometer 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. The degree of radioactivity within the mineralized intervals is highly variable and associated with visible pitchblende mineralization. All intersections are down-hole.  All depths reported of core interval measurements including radioactivity and mineralization intervals widths are not always representative of true thickness.  The orientation of the mineralized intervals tend to follow that of lithologic contacts, and generally dip steeply to the south. Within the Triple R deposit, individual zone wireframe models constructed from assay data and used in the resource estimate indicate that all five zones have a complex geometry controlled by and parallel to steeply south-dipping lithological boundaries as well as a preferential sub-horizontal orientation.

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 U ₃ O ₈ (wt %) and fire assay for gold, while the other half remains on site for reference. All analysis includes a 63 element ICP-OES, uranium by fluorimetry and boron.

PLS Mineralized Trend & Triple R Deposit Summary

Uranium mineralization at the Triple R deposit at PLS occurs within the Patterson Lake Conductive Corridor and has been traced by core drilling over ~3.18km of east-west strike length in five separated mineralized “zones”, which collectively make up the Triple R deposit. From west to east, these zones are R1515W, R840W, R00E, R780E and R1620E. Through successful exploration programs completed to date, Triple R has evolved into a large, near-surface, basement-hosted, structurally controlled high-grade uranium deposit. The discovery hole was announced on November 05, 2012 , with drill hole PLS12-022 from what is now referred to as the R00E zone.

The R1515W, R840W and R00E zones make up the western region of the Triple R deposit and are located on land, where overburden thickness is generally between 55m to 100 m . R1515W is the westernmost of the zones and is drill defined to ~90m in strike length, ~68m across strike and ~220m vertical and where mineralization remains open in several directions. R840W is located ~515m to the east along the strike of R1515W and has a drill-defined strike length of ~430m. R00E is located ~485m to the east along strike of R840W and is drill defined to ~115m in strike length. The R780E and R1620E zones make up the eastern region of the Triple R deposit. Both zones are located beneath Patterson Lake , where water depth is generally less than six metres, and overburden thickness is generally about 50m . R780E is located ~225m to the east of R00E and has a drill-defined strike length of ~945m. R1620E is located ~210m along strike to the east of R780E and is drill defined to ~185m in strike length.

Mineralization along the Patterson Lake Corridor trend remains prospective along strike in both the western and eastern directions. Basement rocks within the mineralized trend are identified primarily as mafic rocks with varying degrees of alteration. Mineralization is both located within and associated with mafic rocks with varying degrees of silicification, metasomatic mineral assemblages and hydrothermal graphite. The graphitic sequences are associated with the PL-3B basement Electro-Magnetic (EM) conductor.
