Fission Hits 11.0% U3O8 Over 5.0m; High Grade Holes Expands R600W, R780E and R1620E

KELOWNA, BRITISH COLUMBIA--(Marketwired - Oct. 20, 2015) - FISSION URANIUM CORP. (TSX:FCU)(OTCQX:FCUUF)(FRANKFURT:2FU) ("Fission" or "the Company") is pleased to announce drill core assays results from an additional 10 angled holes from the summer 2015 program: two holes drilled on the R600W, six on the R780E zone and two on the 1620E zone at its' PLS property, host to the Triple R deposit, in Canada's Athabasca Basin region. Of key importance, the shallow R600W zone, for which a resource estimate has not yet been determined and thus was not included in the recent preliminary economic assessment "PEA" technical report, has once again returned very strong, high-grade intervals. Of additional importance, hole PLS15-416 intersected the strongest high-grade mineralization on line 1125E - opening up the eastern side of the R780E as a new high-grade area. These results have the potential to further improve the economics of the Triple R.

All ten holes returned mineralization, with five holes reporting high-grade intervals.

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

"These results add still more strength to the R600W zone, which speaks to its excellent potential for not only adding pounds to the resource but importantly meaningful pounds that may enhance and improve the already-strong economic features at PLS, as identified in our PEA study. Furthermore, we have seen the strongest high grades on line 1125E on the R780E zone. This is important because it suggests the high-grade potential of the R780E to the east. It's worth noting in relation to this, that we have drilled high-grade mineralization on the R1620E zone a further 495m to the east along trend."

Composited % U3O8 mineralized intervals are summarized in Tables 1, 2 and 3. Samples from the drill core are split in half sections on site. Where possible, samples are standardized at 0.5m down-hole intervals. One-half of the split sample is 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 remains on site for reference. All analysis include a 63 element ICP-OES, uranium by fluorimetry and boron. 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. All depth measurements reported, including sample and interval widths are down-hole, core interval measurements and true thickness are yet to be determined.

PLS Mineralized Trend & Triple R Deposit Summary

Uranium mineralization at PLS has been traced by core drilling along a mineralized trend approximately 2.33km 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, the Triple R has evolved into a large, near surface, basement hosted, structurally controlled high-grade uranium deposit.

The Triple R deposit resource estimate currently consists of only 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 area is covered by approximately 50m to 100m 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 495m west of the Triple R deposit, have significantly upgraded the R600W zone to a very prospective area for further growth of the PLS resource.
