Fission Hits Widest Mineralization to Date Outside of the R780E Zone with 1.5km Step Out from Triple R Deposit
FISSION URANIUM CORP. ("Fission" or “the Company" - https://www.youtube.com/watch?v=ypiqxkXxraU&t=44s) is pleased to announce the results of an additional 2 holes testing the recently-discovered, land-based, R1515W zone where drilling has intersected the widest cumulative mineralization and some of the strongest radioactivity to date outside of the Triple R Deposit, at its’ PLS property in Canada's Athabasca Basin region. The two holes have encountered very wide mineralization and strongly radioactive peaks in multiple stacked zones, at the R1515W zone, which is 1.5km west of the Triple R deposit. Of particular importance, hole PLS17-564 (line 1545W) intersected 135.5m total composite mineralization, including 8.25m total composite >10,000 cps and multiple intervals of >65,535 cps (the maximum reading possible by the RS-121 scintillometer before saturation).
Of additional importance, the nature of mineralization of the R1515W zone, including multiple stacked lenses and wide lateral widths, is showing increasingly similarities to the R780E – the primary zone of the Triple R deposit. The Triple R hosts mineral resources of 81.1M lbs @ 1.83% U3O8 (indicated) in 2.01M tonnes and 27.2M lbs @ 1.57% U3O8 (inferred)in 0.79M tonnes at a cut-off grade of 0.2% U3O8 within the pit boundary and at an incremental underground cut-off grade of 0.25% U3O8.
Drilling Highlights Include:
<s>· </s>1.5km Step Out from Triple R Deposit. The two holes, PLS17-563 and PLS17-564 have encountered wide, high-grade intercepts over 1.5km west of the Triple R deposit.
<s>· </s>Wide, High-Grade Mineralization within Multiple Stacked Lenses Represent Notable Similarities to the Triple R Deposit’s R780E zone. The results from summer drilling at R1515W have encountered geological features with similarities to the R780E zone of the Triple R deposit. Outside of the Triple R deposit, the R1515W is the zone that compares most similarly to the R780E zone with respect to lateral width and style of mineralization.

Ross McElroy, President, COO, and Chief Geologist for Fission, commented
“We are very excited by the results of these drill holes – not only because of the width and strength of the mineralization but of the confirmation that the land-based R1515W zone has notable mineralization similarities to the Triple R deposit’s R780E zone 1.5km to the east. These similarities, including multiple stacked lenses, are reason why the widths we’ve encountered in these last two holes, are so impressive. These features have the potential to rapidly grow mineral resources – as was the case with the R780E zone delineation. The R1515W is still at an early stage and these drill results are highly promising.”
R1515W Zone Summary
The on-land R1515W zone is located within the Patterson Lake Corridor along strike to the west of the R840W zone. A total of 12 holes, 10 of which are mineralized, have traced mineralization over a strike length of 70m and a lateral width of up to 53m wide (line 1515W). Mineralization begins at the top of bedrock, which occurs at 100m depth below surface. The lithologic setting which hosts the mineralization is similar to other zones of the Patterson Lake Corridor, being an overall package dominated by a quartz+feldspar+biotite+garnet gneiss with intercalated steeply south-dipping intervals of silica+sulphide+graphite bearing mafic gneiss. Mineralization occurs within strong hydrothermally altered, structurally controlled sections interpreted as multiple stacked intervals that appear to be parallel to each other and parallel to the mafic gneiss. As is the case particularly with the R780E zone, mineralization morphology is a complex geometry controlled by and parallel to steeply south-dipping lithological boundaries as well as a preferential sub-horizontal orientation.
PLS17-563 (line 1515W) – Collared as an angled hole, mineralization extends approximately 32m down-dip from PLS17-561. Mineralization on line 1515W currently has an across-strike lateral width of 53m.
PLS17-564 (line 1545W) – Collared as an angled hole, mineralization extends approximately 28m down-dip from PLS17-562. Mineralization on line 1545W currently has an across-strike lateral width of 45m.

· Hole PLS17-565 was abandoned due to technical problems with drilling.
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-121 Scintillometer manufactured by Radiation Solutions, which is capable of discriminating readings to 65,535 cps. Natural gamma radiation in the drill hole survey that is reported in both core and reverse circulation "RC" holes this news release was 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 intersection measurements are down-hole. All depths reported of core interval and down-hole gamma measurements including radioactivity and mineralization intervals widths are not always representative of true thickness and true thicknesses are yet to be determined in zones outside of the Triple R deposit. Within the Triple R deposit, individual zone wireframe models constructed from assay data and used in the resource estimate indicate that both the R780E and R00E zones have a complex geometry controlled by and parallel to steeply south-dipping lithological boundaries as well as a preferential sub-horizontal orientation.
PLS Mineralized Trend & Triple R Deposit Summary
Uranium mineralization at PLS occurs within the Patterson Lake Conductive Corridor and has been traced by core drilling approximately 3.18km of east-west strike length in five separated mineralized "zones". From west to east, these zones are: R1515W, R840W, R00E, R780E and R1620E. Thus far only the R00E and R780E have been included in the Triple R deposit resource estimate, where-as the R840W and R1620E zones and the recent addition of the R1515W zone, fall outside of the current resource estimate window.
The discovery hole of what is now referred to as the Triple R uranium deposit was announced on November 05, 2012 with drill hole PLS12-022, from what is considered part of the R00E zone. Through successful exploration programs completed to date, it has evolved into a large, near surface, basement hosted, structurally controlled high-grade uranium deposit.
The Triple R deposit consists of the R00E zone on the western side and the much larger R780E zone further on strike to the east. Within the deposit, the R00E and R780E zones have an overall combined strike length validated by a resource estimate of approximately 1.05km with the R00E measuring approximately 105m in strike length and the R780E zones measuring approximately 945m in strike length. A 225m gap separates the R00E zone to the west and the R780E zones to the east, though sporadic narrow, weakly mineralized intervals from drill holes within this gap suggest the potential for further significant mineralization in this area. The R780E zone is located beneath Patterson Lake which is approximately six metres deep in the area of the deposit. The entire Triple R deposit is covered by approximately 50m to 60m of overburden.
Mineralization remains open 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. The R840W zone, located 495m west along strike of the Triple R deposit, now has a defined strike length of 465m and is still open. The recent discovery of the high-grade R1515W zone located a further 510m to the west of the R840W zone, now has a defined strike length of 70m and is open in multiple directions. The R840W and R1515W zones have significantly upgraded the prospectivity for further growth on land to the west of the Triple R deposit within the Patterson Lake Corridor. The recently discovered high-grade mineralization in the R1620E zone, located 210m to the east along strike similarly has significantly upgraded the prospectivity for further growth of the PLS resource to the east of the Triple R deposit.
