KELOWNA, BRITISH COLUMBIA--(Marketwired - Sept. 23, 2013) - FISSION URANIUM CORP. (TSX VENTURE:FCU)(OTCQX:FCUUF)(FRANKFURT:2FU) ("Fission" or "the Company") the Operator, and its Joint Venture partner Alpha Minerals Inc. are pleased to announce the discovery of a fifth zone of high grade uranium mineralization with off-scale radioactivity on its Patterson Lake South (PLS) property in the Athabasca Basin, Saskatchewan. The first hole on line 585E, PLS13-098, intersected 76m total composite mineralization, including 7.62m total composite off-scale radioactivity. The R585E Zone is located approximately halfway between the R390E and R780E zones: 150m grid east of easternmost edge of the R390E Zone (PLS13-078 on line 435E, see news release August 22, 2013). PLS now comprises five separate zones on strike of each other along a 1.05km trend.

Drilling Highlights include:

--  5th high grade Zone; discovered halfway between R390E and R780E zones 

--  76.0m of mineralization at shallow depth over 107.5m section (62.5m -

    170.0m), including: 

    --  7.62m of off-scale in several narrow discrete intervals ranging from

        0.15m to 2.21m each 

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

"The first hole of Zone R585E has intersected considerable breadth of mineralization and off-scale radioactivity. Just as important is the location - R585E halves the gap between high-grade zones R390E and R780E. This narrowing of the distance between zones is continued proof that PLS is host to a mineralized system of considerable size and strength."

R585E Zone

The R585E Zone is located approx. 150m grid east of the easternmost defined edge of the R390E Zone. The hole was targeted along the northern edge of the low resistivity feature, which is associated with the mineralized east-northeast trending pelitic corridor and a coincident radon in water anomaly. The geologic setting of the R585E zone is similar to other zones, consisting of mineralization primarily associated with sequences of steeply south dipping pelitic lithology with localized mylonites and cataclasites.

Hole PLS13-098 (line 585E) was collared as a vertical hole and completed to a depth of 317.0m. The hole is located approximately 150m grid east of hole PLS13-078 (42.0m of total composite mineralization with 1.25m total composite off-scale...see news release August 22, 2013). A number of discrete intervals of variably radioactive mineralization occur from 62.0m to 283.0m, with the most significant mineralization occurring within a 107.5m section (62.5m to 170.0m) in widths ranging from 1.5m to 33.5m. Four of these intervals contain discrete intervals of off-scale (greater than 9999 cps) radioactivity from 0.09m to 2.21m wide, for a total measured composite of 7.62m of off-scale radioactivity. The intervals of 123.0m - 139.5m and 145.5m - 149.5m are the strongest mineralized sections, containing the majority of the off-scale radioactivity. Basement bedrock was encountered at 62.4m below the surface. Pelitic gneiss occurs from 62.4m to 277.2m. From 277.2m to 317.0m (EOH) basement is comprised of a semipelitic gneiss. Strong mylonites and cataclasites are present from 105.0m to 115.5m, dipping at 10 degrees to 40 degrees to core axis. Moderate to strong chlorite alteration is present from 62.4m to 117.1m and moderate to strong clay alteration from 117.1m to 171.4m.

(i) Scintillometer Instrument: GR-110G                                      

A $6.95M, 44 hole, 11,000m drill program and ground geophysics surveys continues at PLS.

Natural gamma radiation in drill core that is reported in this news release was measured in counts per second (cps) using a hand held Exploranium GR-110G total count gamma-ray scintillometer. 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, core interval measurements and true thickness is yet to be determined.

All holes are planned to be radiometrically surveyed 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.

Split core samples from the mineralized section of core will be taken continuously through the mineralized intervals and submitted to SRC Geoanalytical Laboratories (an SCC ISO/IEC 17025: 2005 Accredited Facility) of Saskatoon for analysis, which includes U3O8 (wt %) and fire assay for gold. All samples sent for analysis will include a 63 element ICP-OES, uranium by fluorimetry and boron. Assay results will be released when received.
