Fission Energy Corp.: Drilling Begins at J Zone, Waterbury Lake, Athabasca Basin

KELOWNA, BRITISH COLUMBIA -- (Marketwire) -- 06/25/12 -- FISSION ENERGY CORP. (TSX VENTURE: FIS)(OTCQX: FSSIF) ("Fission" or the "Company") and its Limited Partner, the Korea Waterbury Uranium Limited Partnership ("the Waterbury Consortium"), are pleased to announce that a $3.11 million Summer 2012 Exploration Program, including 21 drill holes totalling 7,350m with two drills, at its flagship 40,256 ha Waterbury Lake uranium project, located in the eastern part of the Athabasca Basin, is underway. The primary focus of this summer's program will be to continue delineating the J Zone deposit's high-grade unconformity and basement mineralization. All 21, drill holes, to be collared from land-based locations, have been identified along many areas across the J Zone as the Joint Venture continues its efforts to delineate and laterally expand the deposit. Bryson Drilling Ltd. of Archerwill, SK, has been contracted to complete the drill program.

The following summary outlines Fission's Summer 2012 Exploration Program:

--  C $3.11 million budget approved by the Limited Partnership.

--  Utilizing two drill rigs, twenty-one (21) drill holes totalling an
    estimated 7,350m are planned with the objective of delineating and
    expanding known areas of mineralization, both laterally and on strike.
    Fifteen holes will target locations from the eastern part of the J Zone
    to the central main area of the deposit, between Line 75E and Line 420
    W, to extend mineralization where geologic confidence is high. Drill
    locations have been established to the north of the J Zone boundary,
    accessible from land based sites. The remaining six holes will test for
    mineralized extensions along strike to the west between Lines 630W and
    780W.

--  Ground Geophysical work, including a DC Resistivity Survey to identify
    areas of high conductivity, will be carried out at Murphy Lake, located
    in the northwest part of the Waterbury Lake Property. Analysis of
    previously completed airborne geophysical surveys appears to have
    identified a separate feature to the west of the Murphy Lake system,
    which represents a compelling target within this prospective area. Line
    cutting totalling 18.2 line-km and the 17 line-km DC Resistivity Survey
    will focus on this feature.

Fission is the Operator of the program, which is expected to be completed by late August. Results will be announced when available.
