Fission Vertical Step Outs Intersect 18m of 1.32% U308 and 8.5m of 1.92% U308 at "J-Zone" Including Intercepts as High as 3.56% U308

KELOWNA, BRITISH COLUMBIA--(Marketwire - April 28, 2010) - FISSION ENERGY CORP. ("Fission" or the "Company") and its joint venture partner, the KEPCO Consortium, announce "J-Zone" assay results for five previously completed vertical oriented step-out drill holes: WAT10-073, 074, 075, 076A, and 077. Four of the five holes encountered mineralization at the unconformity with hole WAT10-073 intersecting 18.0m grading 1.32% U308 (197.0m-215.0m), including two intercepts of 2m at 3.35% U308 (198.5m-200.5m) and 3.23% U308 (208.0m-210.0m), and one intercept grading 2.49% U308 over 1.50m (212.0m-213.5m). In addition, hole WAT10-077 intersected 8.50m grading 1.92% U308 (204.0-212.5), including 4m at 3.56% U308 (206.5m-210.5m). A summary of the assay results is shown in the accompanying table below.

Composite Parameters

  1. Minimum Thickness: 1.00m
  2. Grade Cut-off: 0.05 U308 (wt%)

All drill intersections are associated with a broad continuous zone of alteration extending from several meters above the unconformity to >25m below the unconformity, with mineralization occurring within this altered system. Overall, these vertical step-out drill holes have demonstrated continuity of high grade mineralization and exceptional widths trending to the west of discovery hole WAT10-063A. Most notably, hole WAT10-073 has identified the widest continuous high grade mineralized intersection from assays received to date. Assays are pending on the remaining eleven drill holes, which further extended the J-Zone's east-west trending mineralized strike length to approximately 90m and 50m wide, north-south, at the time the Winter 2010 drill program was completed. The J-Zone remains open laterally along strike and width. In addition, assays are pending on nine other regional drill holes: WAT10-062, 078, 080, 082, 084, 086, 088, 090 and 092.

All intersections are down-hole, core interval measurements and true thickness is yet to be determined. Given that the mineralization thus far encountered appears to be almost flat-lying, drill intercepts reported herein are approximately true thickness.

An updated map of the J-Zone showing the location of these five drill holes and a table summarizing assay results can be found on the Company's website at http://www.fission-energy.com/s/WaterburyLake.asp

Follow-up drilling at the J-Zone, in addition to testing other high priority land based targets is planned for the summer. Further details will be provided once all data has been collected and analysed.

Split core samples from the mineralized section of core have been 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, platinum and palladium. All samples sent for analysis will include a 63 element ICP-OES, uranium by fluorimetry (partial digestion) and boron. Chemical results will be released when received. Further updates will be provided.
