KELOWNA, BRITISH COLUMBIA–(Marketwired – Aug. 23, 2017) – FISSION URANIUM CORP. (TSX:FCU)(OTCQX:FCUUF)(FRANKFURT:2FU)(“Fission” or “the Company“) is pleased to announce the results of the final three holes of the summer program, testing the recently-discovered, land-based, R1515W zone, where this summer drilling has intersected the widest, mineralization outside of the Triple R Deposit at its’ PLS property in Canada’s Athabasca Basin region. The presence of multiple stacked lenses continues to deliver wide intervals with strong radioactive peaks, at the R1515W zone, which is 2.3km west of the Triple R Deposit’s central part of the R780E zone. Of particular note is hole PLS17-566 (line 1545W), which intersected 107.0m total composite mineralization at shallow depth, including 8.03m total composite >10,000 cps.
The summer 2017 exploration program is now complete. Drilling focused on both zone growth of the recently discovered R1515W zone as well as Pre-Feasibility “PFS” level drilling for metallurgical sample collection and geotechnical rock analysis. A total of 2,626m was drilled in 7 completed holes and 1 abandoned hole on the R1515W zone, with 6 of the 7 holes intersecting anomalous mineralization. PFS drilling included a total of 811m in 3 holes drilled for metallurgical sample collection and 614.4m in 3 completed (and 1 abandoned) geotechnical rock holes.
Drilling Highlights Include:
- Wide, High-Grade Mineralization within Multiple Stacked Lenses
- Hole PLS17-566 (line 1545W):
- 107.0m total composite mineralization over a 158.5m section (between 109.5m to 268.0m), including
- 8.03m total composite >10,000 cps
- 107.0m total composite mineralization over a 158.5m section (between 109.5m to 268.0m), including
Ross McElroy, President, COO, and Chief Geologist for Fission, commented
“As we had hoped, following the very successful results from previous holes, the presence of multiple stacked lenses at the R1515W zone has again delivered impressive mineralization that is wide, high-grade and shallow. The R1515W, 2.3km west of the Triple R deposit’s central area, will remain a high-priority going forward. The land-based mineralized zones, west along strike of the Triple R deposit, are particularly important as they have the potential to enhance the economics of the PLS project.”
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 15 holes, 12 of which are mineralized, have traced mineralization over a strike length of 92m, a lateral across-strike width of up to 63m wide (line 1545W) and a vertical extent of 178m (line 1545W). 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.
PLS17-566 (line 1545W) – Collared as an angled hole, mineralization extends approximately 18m down-dip from PLS17-564. Mineralization on line 1545W currently has an across-strike lateral width of 63m.
PLS17-567 (line 1575W) – Collared as an angled hole, 30m west of line 1545W, no anomalous mineralization was encountered. It is possible that may be encountered further north of this target area.
PLS17-568 (line 1545W) – Collared as an angled hole, mineralization extends approximately 60m down-dip from PLS17-566.

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 is also collected from an in-hole survey that is 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 92m 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.
