Fission Hits Broad High-Grade Mineralization at Eastern Edge of Triple R Deposit (Line 1125E)

Six New High-Grade Holes on zones R600W and R780E

KELOWNA, BRITISH COLUMBIA--(Marketwired - Aug. 11, 2015) - FISSION URANIUM CORP. (TSX:FCU)(OTCQX:FCUUF)(FRANKFURT:2FU) ("Fission" or "the Company") is pleased to announce results from a further ten holes of the 20,000m 60-hole summer drill program at its PLS property in Canada's Athabasca Basin region: three holes drilled on the R600W zone, five drilled on the R780E zone and two holes on the R1620E. Importantly, hole PLS15-416, drilled on the eastern edge of the Triple R's R780E zone (line 1125E), has intersected 3.93m total composite mineralization of >10,000 cps radioactivity - the strongest to date from that area. Of additional importance, step out drilling has expanded the strike length of the high-grade, near-surface R600W zone to a total of 105m.

All ten holes returned mineralization, with six holes returning strongly radioactive mineralized intervals measuring >10,000 cps.

Drilling Highlights Include:

R600W Zone

  • Expanded R600W zone an additional 15m west (to line 675W) by high-grade hole PLS15-408 and a further 15m east (to line 570W) with hole PLS15-404
  • R600W zone now extended to a strike length of 105m

R780E Zone

  • Considerable high-grade mineralization encountered on line 1125E (hole PLS15-416)

Intersection Highlights Include:

  • Hole PLS15-408 (line 675E)
    • 27.0m continuous mineralization (between 124.0m - 151.0m) including:
      • 5.09m total composite mineralization of >10,000 cps radioactivity
  • Hole PLS15-416 (line 1125E)
    • 48.0m total composite mineralization over a 170.0m section (between 207.5m - 377.5m) including:
      • 3.93m total composite mineralization of >10,000 cps radioactivity

Ross McElroy, President, COO, and Chief Geologist for Fission, commented,

"We have now intercepted substantial high-grade mineralization on the far eastern side of the R780E zone (line 1125E), with the strongest mineralization to date in that area. In addition, the high-grade, shallow depth R600W zone has now reached 105m in strike length and continues to show a rapid growth rate with a style of mineralization similar to that of the Triple R's R780E zone, over half a kilometer on-strike to the east."

PLS Mineralized Trend & Triple R Deposit Summary

Uranium mineralization at PLS has been traced by core drilling approximately 2.3km of east-west strike length in four separate mineralized "zones". From west to east, these zones are; R600W, R00E, R780E and R1620E.

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 strike length of approximately 1.2km with the R00E measuring approximately 125m in strike length and the R780E zones measuring approximately 900m 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 zones are 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 50 m of overburden.

Mineralization remains open along strike both to the western and eastern extents. Mineralization is both located within and associated with a metasedimentary lithologic corridor, associated with the PL-3B basement Electro-Magnetic (EM) Conductor. Recent very positive drill results returning wide and strongly mineralized intersections approximately 555m west of the Triple R deposit, have significantly upgraded the R600W zone to a very prospective area for further growth of the PLS resource.

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. 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. Individual zone wireframe models constructed from assay data 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. All depths reported of core interval measurements including radioactivity and mineralization intervals widths are not always representative of true thickness and thus true thicknesses are yet to be determined.

Samples from the drill core will be split in half sections on site. 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, while the other half will remain on site for reference. Analysis will include a 63 element ICP-OES, and boron.
