RETRANSMISSION: Fission Energy: PLS JV Hits 34m of 4.92% U3O8 in Upper Zone of PLS13-038 Including 12.5m at 12.38%

KELOWNA, 03/25/13 - Fission Energy Corp. ("Fission" or "the Company), and its 50% Joint Venture partner Alpha Minerals Inc., are pleased to report initial assay results from the ongoing winter drill program on its Patterson Lake South (PLS) Property. These assay results are from drill hole PLS13-038, the first hole drilled on the R390E zone.

Composited drill hole mineralized intersections for PLS13-038 returned two broad zones of uranium mineralization:


UPPER URANIUM ZONE = 34m (87.0m - 121.0m):

- 34.0m @ 4.92% U3O8;
- Including 12.5m @ 12.38% U3O8
- Highest assay in the interval: 35.1% U3O8 over 0.5m


LOWER URANIUM ZONE = 17.5m (126.5m - 144.0m)

- 17.5m @ 0.96% U3O8;
- Including 5.5m @ 2.07% U3O8


PLS13-038 (see news release Feb. 19, 2013) is part of the R390E zone 385m grid east of the discovery hole PLS12-022 (see news release December 5, 2012)


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

"We are extremely pleased with the recent assay results from PLS13-038. As was the case with the assay results from R00E, we have once again confirmed the existence of high-grade uranium mineralization within wide intersections at shallow depth. That is, two uranium zones along a strike length of 400m. As the winter program is still ongoing, we will continue to test and delineate the structure of this uranium system."

Composited U3O8 mineralized intervals are summarized in Table 1 below. Samples from the drill core are split in half on site. Most 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. The results show that the uranium is concentrated primarily in two zones beginning at relatively shallow depth in basement graphitic metapelitic lithology and with continuous substantial widths. Uranium concentration is well developed throughout the mineralized sections with assays being relatively consistent throughout. In addition, there are several narrower intervals of low grade uranium mineralization between 165.0m - 181.0m. Not all assay results have been received for PLS13-038, but the outstanding intervals are not expected to be anomalous.

Hole PLS13-038 was collared as a vertical hole and was completed at a depth of 221.6m. The collar is located 385m grid east of discovery hole PLS12-022 (8.5m @ 1.07% U3O8; see news release December 5, 2012). The relevant geological features of the hole are as follows: At 48.8m depth, a thin (1.9m wide) cap of probable Devonian Sandstone was encountered which overlies the semi-pelite gneiss hanging wall that constrains an intercalated package of pelite graphitic pelite gneiss. Occasional pegmatite injections were observed throughout the pelite, graphitic pelite, and semi-pelite units. In general, the strong mineralization is associated with flecks, blebs, clots, and veins of pitchblende. Of note, wormhole style mineralization was observed for the first time. Moderate to strong clay, chlorite, and hematite alteration were observed throughout the mineralization.

Split core samples were submitted to SRC Geoanalytical Laboratories (an SCC ISO/IEC 17025: 2005 Accredited Facility) of Saskatoon for assay analysis, which includes a 63 element ICP-OES, uranium by fluorimetry (partial digestion), and boron. Samples within mineralized intervals and any samples which return greater than 500ppm U, are assayed for weight % U3O8, as well as fire assayed for gold. Further assay results will be released when received.
