Fission Resource Expansion Drilling on R840W Zone Hits High-Grade Mineralization in 19 Holes

Results include major holes such as 57.5m of continuous mineralization, with 19.15m of total composite >10,000 cps

KELOWNA, BC, Aug. 31, 2021 /CNW/ - FISSION URANIUM CORP. ("Fission" or "the Company") is pleased to announce scintilometer results from the summer 2021 "resource upgrade" drill program on the R840W zone at its' PLS project, in the Athabasca Basin region of Saskatchewan, Canada. All 25 holes hit mineralization, with nineteen intercepting significant intervals of >10,000 cps radioactivity. This includes PLS21-624 (line 630W), which intersected 57.5m of continuous mineralization, including 19.15m of total composite radioactivity >10,000 cps (with a peak of 62,400 cps). Assays are still pending and will be released when received. The goal of the summer resource drilling is to upgrade the majority of the R840W zone by decreasing the spacing between drill hole mineralized intercepts with the goal of upgraded to Indicated classification, for potential use in the Feasibility Study.  The resource upgrade drilling was conducted in conjunction with the on-going Phase 1 Feasibility work at PLS, focusing on drilling for geotechnical, hydrogeological, geochemical and metallurgical data (see News Release June 10, 2021). 

Ross McElroy, President and CEO for Fission, commented, "Our summer resource drilling at the R840W zone has been very successful. The goal was to expand and upgrade this important zone, which is the largest of those not currently included in the Triple R deposit, for potential inclusion in the upcoming feasibility study. We hit mineralization with all 25 holes, testing over 353m of strike length of the R840W zone, the majority of which intersected considerable high-grade intervals. As we await confirmation with assay results, we believe this represents a strong validation of our growth strategy as we continue to develop the project.

Drilling Highlights

  • 100% Hit Rate; Majority of Holes Hit High-Grades. All 25 holes hit significant mineralization, including 19 with high-grade intercepts.

  • R840W Zone Resource Drilling. The holes successfully targeted specific, mainly "inferred" categorized areas of the R840W zone over ~353m of strike length between holes PLS21-624 and PLS21-631, using step out and infill drilling to achieve spacing of ~15m x 20m (horizontal / vertical), with the aim of conversion from Inferred to Indicated. The R840W zone is the 2nd largest of five high-grade zones that make up the Triple R deposit. Although the R840W has been used in the global resource estimate for the Triple R, due to it currently being mainly Inferred classification, it was not considered in the economic analysis of the Prefeasibility Study. If assay results and subsequent modeling provide confirmation that the desired hole spacing has been achieved and at acceptable grade, then the R840W zone can be upgraded to Indicated and then considered for inclusion into the Feasibility study.

Highlight intersections from the drill program include:

  • Hole PLS21-624 (line 630W)
    • 57.5m continuous mineralization over a 57.5m interval (between 109.0m to 166.5m), includin
      • 19.15m of total composite mineralization >10,000 cps
  • Hole PLS21-635 (line 750W)
    • 56.0m total composite mineralization over a 78.0m interval (between 101.5m to 179.5m), includin
      • 7.8m of total composite mineralization >10,000 cps
  • Hole PLS21-633 (line 930W)
    • 27.0m total composite mineralization over a 47.0m interval (between 154.5m to 201.5m), including
      • 6.75m of total composite mineralization >10,000 cps

The R840W zone is located approximately 485m to the west along strike of the Triple R deposit's R00E zone.

As detailed in the report dated January 07, 2019 and with an effective date of September 19, 2019 and titled Pre-Feasibility Study on the Patterson Lake South Property Using Underground Mining Methods, Northern Saskatchewan, Canada, the R840W is currently defined using CIM definitions (2014) for mineral resources at a cut-off of 0.25% U3O8 of:

  • Indicated Mineral Resource: 88,000 tonnes at 1.68% U3O8 yielding 3,300,000 lbs U3O8
  • Inferred Mineral Resource: 280,000 tonnes at 1.86% U3O8 yielding 11,500,000 lbs U3O8

At this time, mineral reserves have not been estimated for the R840W zone.

Natural gamma radiation in drill core that is reported in this news release was measured in counts per second (cps) using either a hand-held RS-230, RS-125 or RS-121 Scintillometer, all manufactured by Radiation Solutions, which are capable of discriminating readings up to 65,535 cps. In each hole, natural gamma radiation is also recorded in a down-hole survey measured in counts per second (cps) using a Mount Sopris 2GHF-1000 Triple Gamma probe, which allows for more accurate measurements in high grade mineralized zones.  The Triple Gamma probe is preferred in zones of high-grade mineralization.  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 5 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 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.

PLS Mineralized Trend & Triple R Deposit Summary

Uranium mineralization of the Triple R deposit at PLS occurs within the Patterson Lake Conductive Corridor and has been traced by core drilling over ~3.18 km 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 55 m to 100 m.  R1515W is the western-most of the zones and is drill defined to ~90 m in strike-length, ~68 m across strike and ~220 m vertical and where mineralization remains open in several directions.  R840W is located ~515 m to the east along strike of R1515W and has a drill defined strike length of ~430 m.  R00E is located ~485 m to the east along strike of R840W and is drill defined to ~115 m in strike length.  The R780E zone 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 50 m.  R780E is located ~225 m to the east of R00E and has a drill defined strike length of ~945 m.  R1620E is located ~210 m along strike to the east of R780E, and is drill defined to ~185 m in strike length.

The Company completed and filed a prefeasibility "PFS" study on November 07, 2019 titled "Pre-Feasibility Study on the Patterson Lake South Property Using Underground Mining Methods, Northern Saskatchewan, Canada".  The report summarizes the Pre-Feasibility Study ("UG PFS"), which outlines an underground-only mining scenario for PLS which to date has only considered the R00E and R780E zones.  Further work, including additional drilling may provide sufficient data for future inclusion of the R1515W, R840W and R1620E zones into the Feasibility Study mine plan.

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 volcanic rocks with varying degrees of alteration.  Mineralization is both located within and associated with mafic volcanic intrusives 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.
