KELOWNA, BRITISH COLUMBIA--(Marketwired - April 5, 2013) - FISSION ENERGY CORP. ("Fission" or the "Company") (News - Market indicators)(OTCQX:FSSIF) and its Limited Partner, the Korea Waterbury Uranium Limited Partnership ("the Waterbury Consortium"), are pleased to announce that the Winter 2013 drill program on its Waterbury Lake property is now complete. A total of 68 drill holes and 11 restarts were completed comprising 21,012.9 meters. The program focused on the delineation and growth of the J Zone. Drilling was segregated into areas A, B and C within the J Zone (see attached map) and the primary objective was expansion of the zone both west and north of the known mineralized area. Area C drill results recorded significant mineralization in several holes, including widths of up to 22.5m (WAT13-346). 

Highlights of the program include:

• 68 drill holes were completed, in a total of 21,012.9 meters
• Mineralization was found in 35 holes or 51% of the holes in the program
• All holes were targeted to further delineate and expand the mineralized area of the J Zone covering all 3 areas (Area A, B and C)
• Area C: WAT13-346 (line 500W) intersected a 22.5m wide interval (196.0m - 218.5m) of weak to strong radioactive mineralization, including a 0.1m interval of off-scale (>9999 cps) radioactivity

J Zone Area A:

Area A is the eastern most section of the J Zone located between lines L120E and L210W. A total of 20 holes were drilled in this region of which 5 were mineralized, intersecting weak to off-scale radioactivity. Drilling in Area A focused on testing for the extension of basement hosted mineralization adjacent to Rio Tinto's Roughrider deposit and further delineating the northern boundary of the J Zone for unconformity associated mineralization.

Area A drill hole highlights:

• WAT13-359 (line 070E) was drilled along the eastern boundary of the J Zone and intersected a 4.0m wide zone (209.5 - 213.5m) of weak to off-scale basement hosted radioactivity, including a 0.1m interval of off-scale (>9999 cps) radioactivity. Two subordinate zones of weak to moderate basement hosted radioactivity occurred to a depth of 226.5m.
• WAT13-345 (line 150W) intersected a 12.0m wide zone (184.5 - 196.5m) of weak to moderate uranium mineralization straddling the unconformity (190.0m). This intersection extends the J Zone boundary approximately 10m to the north on line 150W
• WAT13-373 (line 120W) intersected a 3.0m interval of weak to moderately radioactive basement mineralization 45m to the north of the current delineated boundary. This intersection represents the northernmost mineralized intersection of the J Zone.

Hole Summary for Area A:

* Scintillometer Instrument: GR-110G

J Zone Area B:

Area B is the central section of the J Zone located between lines 210W and 435W. A total of 18 holes were drilled in this region of which 11 were mineralized.

Drilling in Area B focused on drill testing open areas to the north and south of the J Zone Deposit delineated boundary.

Area B drill hole highlights:

• WAT13-338 (line 405W) intersected a 5.0m wide interval (199.5 - 204.5m) of weak to strongly radioactive unconformity associated mineralization, including a 0.1m wide interval of off-scale (>9999 cps) radioactivity.
• WAT13-352A (line 250W) intersected a 19.0m wide zone (204.5 - 223.5 m) of weak to moderate radioactivity straddling the unconformity (206.0 m). This intersection fills in a gap to the south on line 255W.
• WAT13-398 (line 260W) intersected a 15.0m wide zone (195.5 - 210.5 m) of weak to moderate radioactivity straddling the unconformity (197.0 m). This intersection extends the J Zone boundary to the north on line 255W.

Hole Summary for Area B:

* Scintillometer Instrument: GR-110G

J Zone Area C:

Area C is the western most section of the J Zone and is located west of (and including) line 435W. The J Zone had previously been delineated westward to line 540W (hole WAT12-289). Winter 2013 drilling in Area C was designed to test for additional associated mineralization between line 435W and line 540W as well as test westward to line 660W along trend to assess the potential for mineralization beyond the currently defined western boundary.

A total of 30 holes were drilled in Area C. Eighteen holes were mineralized including 2 westward step-out drill holes (WAT13-380 and 383) which extended the J Zone mineralized boundary an additional 20m west to line 560W (WAT13-380). Several holes in Area C intersected wide zones of mineralization (up to 22.5m wide in WAT13-346), confirming the potential of Area C as a significant part of the J Zone Deposit. 

Nine holes between lines 495W to 510W (WAT13-346, 350, 354, 357A, 361A, 364, 368, 371 and 374) were drilled with a collar azimuth of ~275°, in order to optimally intersect mineralization where a complex north-south fault was interpreted to off-set mineralization. Several of these holes intersected significant widths of mineralization higher up in the sandstone above the unconformity than previous proximal north-south oriented holes had encountered. 

Area C drill hole highlights:

• WAT13-346 (line 500W) intersected a 22.5m wide interval (196.0m - 218.5m) of weak to strong radioactive mineralization, including a 0.1m interval of off-scale (>9999 cps) radioactivity, that straddles the unconformity (209.5m).
• WAT13-368 (line 500W) intersected an 18.0m wide interval (188.5m - 206.5m) of weak to strong radioactive mineralization, including a 0.1m interval of off-scale (>9999 cps) radioactivity, occurring dominantly in the sandstone directly above the unconformity (203.9m). This intersection is approximately 10m north of the currently defined boundary of the J Zone.
• WAT13-366 (line 490W) intersected a 12.5m wide interval (187.0m - 199.5m) of weak to strong radioactive mineralization, including a 0.2m interval of off-scale (>9999 cps) radioactivity, primarily hosted in the lower sandstone directly above the unconformity (198.4 m).
• WAT13-377 (line 525W) intersected a 12.0m wide interval (218.5m - 230.5m) of weak to strong radioactive basement mineralization, including several narrow intervals totaling 0.31m of off-scale (>9999 cps) radioactivity.

Hole Summary for Area C:

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 either a Mount Sopris 2GHF-1000 Triple Gamma probe or, as a back-up, a Mount Sopris 2PGA-1000 Natural Gamma probe. The Triple Gamma probe is preferred in zones of high grade mineralization. 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 is yet to be determined.

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 scan, uranium by fluorimetry (partial digestion), and boron. Samples within mineralized intervals and any samples which return >500ppm U, are assayed for weight % U₃O₈, as well as fire assayed for gold. Further assay results will be released when received.
