Fission Energy Corp.: New Ground Staked on South Flank of PLS Property

KELOWNA, BRITISH COLUMBIA -- (Marketwire) -- 02/15/12 -- Fission Energy Corp. ('Fission or 'the Company') (TSX VENTURE: FIS)(OTCQX: FSSIF) and its 50% Joint Venture (JV) partner ESO Uranium Corp., announce that six new claims totalling approx. 8,170 hectares (20,200 acres) have been staked along the south boundary of the PLS Property. The new staking has increased the size of the PLS Property to approximately 31,039 hectares in 17 mineral claims.

The six new claims were staked to cover possible south trending extensions of the large 5 km X 0.9 km wide high grade uranium boulder field discovered by the JV in June, 2011 (see news release dated July 27th 2011). The geological setting compares favourably with the PLS boulder field discovery area, and exhibits potential for shallow, basement hosted uranium deposits. In addition, the new claims envelop the southwest extensions of several historical basement conductors, including the Derkson Conductor Corridor, where previous exploration was conducted in the 1970s by the Saskatchewan Mining & Development Corporation (now Cameco). This area will be evaluated for uranium mineralization that may extend to the southwest from the extensive western front of the uranium boulder field.

The Joint Venture has contracted Geotech Ltd. to conduct a 1,711 line-km helicopter time-domain electromagnetic (EM) survey. This survey will provide data for interpreting the bedrock lithology, indentifying structural and alteration features, in addition to contributing high resolution images of bedrock EM conductors, which may represent graphitic zones and/or faults. All of these elements are related to the occurrence of high grade uranium mineralization found in the Athabasca Basin region. The survey is currently underway.

Drilling, as part of the JV's expanded $2.76 million exploration program at PLS (see press release dated January 16, 2012) is expected to resume later this month. Approximately 4,000m in 33 core and reverse circulation drill holes is now planned. This program is designed to locate the source area of the boulders by drilling for radioactive till sheets in the overburden on the up ice (northeast) side of the uranium boulder field, as well as testing targets identified from ground geophysics DC Resistivity and EM surveys. Details will follow once the projects are underway.

Lastly, as per the terms of the JV Agreement, Fission is now Operator and assumes management of the PLS exploration project as of January 1st 2012.

PLS is a 50%/50% Joint Venture held with ESO Uranium Corp. (ESO). PLS is accessible by road with primary access from all weather Highway 955, which runs north to the former Cluff Lake mine, (greater than 60M lbs of U3O8 produced), and passes through the nearby UEX-Areva Shea Creek discoveries located 50km to the north, currently under active exploration and development.
