Fission Hits Highest Grades to Date at R1620E Zone Including 9.5m @ 13.56% U3O8

KELOWNA, BRITISH COLUMBIA--(Marketwired - Oct 12, 2016) - FISSION URANIUM CORP. (FCU.TO)(FCUUF)(2FU.F) ("Fission" or "the Company") is pleased to announce that assay results confirm the strongest high-grade mineralization to date at the R1620E zone and further high-grade holes at R840W zone at its PLS property, host to the Triple R deposit, in Canada's Athabasca Basin region. Both zones are presently outside of the Triple R resource area. The assay results include hole PLS16-500 on zone R1620E (line 1545E) with 9.5m @ 13.56% U3O8 within a larger interval of 27.0m @ 5.0% U3O8. The wide, high-grade mineralization encountered at both zones, continues to highlight the strength and prospectivity of the 2.63km mineralized trend at PLS - the largest lateral footprint in the Athabasca Basin region.

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

"These results include the highest-grade mineralization seen to date at the R1620E zone, as well as strong grades at the R840W zone. Both of these shallow-depth, high-grade zones are outside of the current resource estimate for the Triple R and remain open in multiple directions."

Assay Highlights Include:

R1620E zone (high-grade, shallow zone at eastern end of mineralized trend)
PLS16-500 (line 1545E) key interval:

  • 27.0m @ 5.0% U3O8 (86.0m to 113.0m), including:

    • 9.5m @ 13.56% U3O8 (98.5m to 108.0m)

PLS16-498 (line 1515E) key interval:

  • 26.5m @ 3.60% U3O8 (78.5m to 105.0m), including:

    • 9.0m @ 8.56% U3O8 (89.0m to 98.0m)

R840W Zone (high-grade, shallow land-based zone recently merged with R600W zone)
PLS16-495 (line 855W) key interval:

  • 10.0m @ 3.74% U3O8 (138.0m to 148.0m), including:

    • 1.0m @ 8.92% U3O8 (139.5m to 140.5m)

    • 4.0m @ 5.92% U3O8 (142.5m to 146.5m)

Composited % U3O8 mineralized intervals are summarized in Tables 1 and 2. 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 includes 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. Similar geometrical relationships appear to be the case with the R840W and R1620E zones as well. All depth measurements reported, including sample and interval widths are down-hole, core interval measurements and true thickness are yet to be determined.
