Fission Hits 13.41m Total Composite "Off-Scale" Radioactivity in 48.5m of Mineralization at R780E Zone

August 12, 2013

KELOWNA, BRITISH COLUMBIA--(Marketwired - Aug. 12, 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 results for hole PLS13-080 at R780E Zone, the first hole drilled on the R780E zone this program. With 13.41m composite off-scale (>9999 cps) mineralization, including 7.6m continuous off-scale, PLS13-080 has returned the widest continuous and strongest results encountered so far at R780E Zone.

The hole, which is located approximately 10m grid south of PLS13-060 (line 780E), has delivered mineralized intersections that appear similar to many of those encountered at the R390E Zone, such as hole PLS13-038 which assayed 4.92% U3O8 over 34.0m (see news release March 24, 2013).

PLS13-080 Drilling Highlights include:

  • Multiple zones of basement mineralization from 122.5m - 318.5m
  • Main Zone - 48.5m (122.5m - 171.0m) wide broad zone of variable radioactivity from weak-to-strong comprised of 4 intervals each separated by narrow intervals of barren rock (1.5m - 2.5m wide) including:
    • 39.0m wide interval (128.0m - 167.0m) of well-developed mineralization including:
    • 13.41m total composite total off-scale (>9999 cps) radioactivity in several discrete intervals including:
    • 7.6m of continuous off-scale (>9999 cps) radioactivity.
  • Several narrower intervals of mineralized anomalous radioactivity from 201.5m - 318.5m, including:
    • 11.5m wide interval (236.0m - 247.5m) of weak to locally strong radioactivity, including:
    • 0.3m of off-scale (>9999 cps) radioactivity.
  • Extends the width of the R780E zone to approximately 45m on line 780E.

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

"Hole PLS13-080 is by far the most significant drill hole at R780E to date, showing similar results to those at R390E. All three zones (R00E, R390E and R780E), which have been traced on-strike over a +855m ENE trending corridor, now have drill holes with wide and robust mineralization."

R780E Zone:

The R780E zone discovery was the result of follow-up by drilling of a radon in water anomaly identified during the January - February 2013 survey conducted by RadonEx Exploration Management. The radon anomaly is on trend to the E-NE from the R00E and R390E zones, and is situated within a resistivity low corridor proximal to an inferred north-south cross cutting structure.

Hole PLS13-080 (line 780E) was collared as a vertical hole and completed to a depth of 347.0m. The hole is the 4th hole drilled on the R780E zone and is collared approximately 10m grid south of PLS13-060 (which intersected multiple zones of basement mineralization including 7.0m @ 1.22% U3O8 (see news release June 5, 2013). The drill-hole is located south of the PL-3B EM conductor axis, which differs from mineralization found so far at the R00E and R390E zones north of the PL-3B conductor. Multiple zones of mineralization were intersected in the basement lithology between 122.5m - 318.5m, ranging in width from 0.5m to 48.5m. The main interval of mineralization is over a width of 48.5m (122.5m - 171.0m) which is characterized by variably weak to strong radioactivity throughout, with occasional narrow intervals (1.5m - 2.5m wide) of barren rock. A total composite of 13.41m of "off-scale" (>9999 cps) radioactivity is present in several discrete intervals ranging in width from 0.1m to 7.6m. A lower zone of weak to strongly radioactive mineralization is present over 11.5m width (236.0m - 247.5m), including a 0.3m interval of "off-scale" radioactivity. With mineralization present down to 318.5m, this represents the deepest mineralization to date on the PLS property. The top of the basement rocks were encountered at 54m depth. From 54m - 171m the rocks consist primarily of clay altered and steep to moderately dipping foliated quartzitic gneiss. From 171m - 347m the rocks comprise alternating sequence of quartzitic gneiss / pelitic gneiss / pelitic granofel.

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.
