KELOWNA, BRITISH COLUMBIA--(Marketwired - Sep 4, 2013) - FISSION URANIUM CORP. (TSX VENTURE:FCU)(FCUUF)(2FU.F) ('Fission' or 'the Company') the Operator, and its Joint Venture partner Alpha Minerals Inc. are pleased to report assay results from hole PLS13-075 on drilled on line 330E on the Western region of Zone R390E, at their Patterson Lake South (PLS) property, Saskatchewan. The main zone of mineralization returned an interval of 9.08% U3O8 over 54.5m, including a higher grade core of 21.76% U3O8 over 21.5m. With an overall Grade x Thickness (GT) value of 494.8 for this interval, this is now the best mineralized hole to date at PLS.
PLS13-075 is located 30m grid west of hole PLS13-061 (23.5m @ 1.39% U3O8…see news release dated June 5, 2013).
Assay Highlights
-
54.5m @ 9.08% U3O8 (61.0m - 115.5m) with GT 494.86 including:
-
21.5m @21.76% U3O8 (68.5m - 90.0m) with GT 467.84
-
Highest assay in the interval: 52.2% U3O8 over 0.5m (74.0m - 74.5m)
-
Intermittent narrower zones of weaker mineralization, up to 11.5m wide each, are present from 118.0m to 177.5m
Ross McElroy, President, COO, and Chief Geologist for Fission, commented,
"This is a spectacular mineralized interval from the R390E Zone. It confirms a particularly high-grade of uranium mineralization within wide intersections at shallow depth. With a mineralized interval grade x thickness (GT) value of 494.8m%, PLS13-075 delivers not only the best results to date on the PLS property but on a level with the best holes within the Athabasca Basin district."
Composited U3O8 mineralized intervals are summarized in Table 1 below. Samples from the drill core are split in half on site. Where possible, samples are standardized at 0.5m down-hole intervals. One-half of the split sample is sent to the laboratory for analysis and the other half remains on site for reference. All depth measurements reported, including sample and interval widths are down-hole, core interval measurements and true thickness are yet to be determined.

Drillhole PLS13-075 was collared as a vertical hole and was completed at a depth of 248.0m. Mineralized zones as defined by assays of >0.05% U3O8 over >0.5m are present in discrete intervals over a 120.0m wide section (57.5m - 177.5m) each ranging in width from 0.5m to 54.5m wide. The main mineralized horizon was encountered from 61.0m - 115.5m and returned a composited interval of 9.08% U3O8 over 54.5m, including a high-grade core (68.5m - 90.0m) that returned 21.76% U3O8 over 21.5m and is associated with strongly hydrothermally altered gneiss. Several additional narrow intervals of generally weaker mineralization were present from 118.0m to 177.5m (see Table 1). A thin cap of Devonian sandstone was encountered from 47.0m to 49.3m, overlying a quartzitic gneiss to a depth of 55.6m. The quartzitic gneiss was underlain by a foliated and locally faulted strongly altered locally strongly graphitic pelitic gneiss. Foliation is generally moderate to steep to core axis at 020° to 048°.
