KELOWNA, BRITISH COLUMBIA -- (Marketwire) -- 03/18/13 -- FISSION ENERGY CORP. (TSX VENTURE: FIS)(OTCQX: FSSIF) ("Fission" or "the Company"), and its Joint Venture partner Alpha Minerals Inc. are pleased to announce the discovery of a third zone of uranium mineralization and off-scale radioactivity located 780 m east of the original discovery on its Patterson Lake property in the Athabasca Basin, Saskatchewan.

This news release is for results from two diamond drill holes completed 780m east along trend of the R00E zone (initial discovery zone). These holes are approximately 390m east of the recently announced drill hole PLS13-038 at R390 Zone, the second zone of mineralization discovered on the property.

Holes PLS13-048 and 055 were both drilled on section L780E. PLS13-055 intersected three radioactive intervals within sheared, graphitic, chloritic, sulfide-bearing metapelitic gneiss, including two discrete narrow intervals of off-scale radioactivity.

Drilling Highlights include:

-- PLS13-048 (L780E) intersected a band of weak to moderate mineralization over 22m (155.0m - 177.0m). This initial identification of mineralization in this area led to the step-out PLS13-055 15m to the south.-- PLS13-055 (L780E) intersected three intervals of weak to strong mineralization (5.0m, 5.5m and 11.0m wide respectively) between 109.0m to 176.5m downhole, including 2 intervals (0.1m and 0.8m wide) of off- scale (greater than 9999 cps) radioactivity in the 2 lower zones. All three intervals of significant mineralization occur within graphitic shear zones.



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

"With the discovery of this mineralization at section L780E, we have now identified 3 separate mineralized zones along strike at PLS. Not only are we expanding the area of mineralization but with each new hole we are gaining a greater understanding of the underlying geology of what has become a very significant region of radioactive mineralization."

Description of Drill Results - L780E

The drill target area at section 780E was designed primarily to test a radon in water anomaly with a value of 3.1 pCi/L. The radon anomaly is on trend to the E-NE from the R00E and R390E zones, and is situated at the east end of the PL-3B EM conductor and associated resistivity low corridor that is terminated by an inferred cross cutting structure.

Hole PLS13-048 is vertical, and tests the center of the radon in water anomaly. A 22.0m interval (155.0m - 177.0m) of weak to moderate radioactivity was intersected in a semipelitic gneiss, below a sequence of alternating pelitic and semipelitic gneiss. Radioactivity within this interval reached up to 2800 cps.

Hole PLS13-055 was collared vertical and was a 15m step-out grid south of PLS13-048. Basement rock from 55.0 to 105.5m consists of alternating sequence of semipelitic and pelitic gneiss. From 105.5m to 190.7m, basement rock is dominantly a pelitic gneiss with pronounced intervals of graphitic shear zones. The shear zone is sub-vertical, with fabrics at low angles to drill core. Within this interval there are multiple zones with anomalous radioactivity ranging in widths from 0.5m - 11.0m (see Table 1). Strong radioactivity is recorded in three intervals of sheared graphitic politic gneiss with millimeter-scale blebs of pitchblende:

1. 109.0m - 114.0m (5.0m) - weak to strong radioactivity with measurements up to 9000 cps2. 139.5m - 145.0m (5.5m) - weak to strong radioactivity including a 0.1m interval of off-scale (greater than 9999 cps) radioactivity3. 165.5m - 176.5m (11.0m) - weak to strong radioactivity including a 0.8m interval of off-scale (greater than 9999 cps) radioactivity



Basement rock from 190.7m to 261.2m (EOH) consists of a semipelitic gneiss.

Results at the R780E Zone expand significantly strike extent of uranium mineralization at Patterson Lake along the main target corridor of conductors associated with a resistivity low anomaly. Additional drilling is planned prior to the completion of the current winter program in order to further evaluate this new zone.

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. Borehole radioactivity is measured downhole using a Mount Sopris 2GHF-1000 Triple Gamma probe. 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 are yet to be determined.

For clarity, it was stated in the March 13, 2013 news release that drill hole PLS13-053 in the R780E Zone had deviated slightly to a dip of -89.26 degrees to the southeast, when in fact it had deviated to a dip of -86.20 to the southeast.

An ongoing field program is in progress. This includes approximately 8000m of core drilling to further delineate and define the mineralized region identified during the summer 2012 program. As well, a Moving Loop Time Domain Electro-Magnetic survey (MLTDEM) was completed on this trend to assist in resolving the geophysical conductors and interpretive structural information. This survey will be used to identify prospective drill targets in the immediate area of mineralization and further along strike.

All holes are planned to be radiometrically surveyed using a Mount Sopris 2GHF-1000 Triple Gamma probe, which allows for 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.
