Fission Hits 99.5m Total Composite Mineralization at Line 750E, Including 6.87m Total Composite "Off-Scale" at PLS

End of Summer Lake Drilling Sees Strong Expansion of R780E Zone

KELOWNA, BRITISH COLUMBIA--(Marketwired - Oct 16, 2013) - Fission Uranium Corp. (TSX VENTURE:FCU)(OTCQX:FCUUF)(FRANKFURT:2FU) ("Fission" or "the Company") the Operator, and its Joint Venture partner Alpha Minerals Inc. are pleased to announce results for the final ten lake holes of the summer program at their Patterson Lake South (PLS) property in Canada's Athabasca Basin, all of which intersected significant mineralization. Of particular note are holes PLS13-109 (99.5m total composite mineralization, including 6.87m total composite "off-scale") and PLS13-097 (90.0m total composite mineralization, including 6.35m total composite "off-scale") in zone R780E.

Drilling Highlights include:

• PLS13-109 (line 750E)
  • 99.5m total composite mineralization (105.5m - 334.5m)including:
    • 6.87m total composite off-scale (>9999 cps) radioactivity
      
      
• PLS13-097 (line 795E)
  • 90.0m total composite mineralization (74.5m - 254.5m)including:
    • 6.48m total composite off-scale (>9999 cps) radioactivity
      
      
• PLS13-108 (line 810E)
  • 103.5m total composite mineralization (80.5m - 234.5m), including:
    • 3.25m total composite off-scale (>9999 cps) radioactivity
      
      

Holes PLS13-101, PLS13-105, PLS13-107 (zone R780E); Holes PLS13-104 (zone R390E); Holes PLS13-106 (zone R585E); PLS13-090, PLS13-103 (zone R1155E) all intersected significant degrees of mineralization.

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

"These holes represent a strong end to the summer's hugely successful barge-based lake drilling which has seen a 100% mineralized hit rate. The lake drilling has given us 5 zones along a total strike length of 1.035km with high-grade mineralization in all 5 zones. Summer drilling has expanded the 3 previously identified zones (R00E, R390E and R780E) and discovered two new zones (R585E and R945E). The results at R1155E, has given us indications that the mineralized system remains open to the east and may extend the strike length of mineralization for at least a further 200m."

R390E Zone

The R390E zone refers to the zone of mineralization currently defined over 255m of strike length between line 225E (hole PLS13-093) and line 480E (PLS13-088). One additional hole was drilled on the R390E zone since the last update (see news release September 27, 2013). PLS13-104 was a vertical collared hole on line 465E, 15m grid west of PLS13-088. A 3.6m wide interval of Devonian sandstone (50.0m - 53.6m) overlies a basement pelitic gneiss, transitioning to semipelitic gneiss from 210.4m to the end of hole (309.2m). Several intervals of undifferentiated mylonites are present within the pelitic sequence, in intervals ranging from 1.7m to 20.6m wide. Radioactive mineralization occurs in several discrete intervals between 53.5m and 212.0m, ranging from 0.5m to 19.5m wide for a total composite of 70.0m of mineralization, including a total composite of 3.02m of off-scale radioactivity in intervals of 0.15m to 1.48m.

R390E

R585E Zone

The R585E zone refers to the zone of mineralization currently defined on line 585E. One additional hole was drilled on the R585E zone since the last update (see news release September 23, 2013). PLS13-106 was a vertical collared hole on line 585E, 10m grid north of PLS13-098. Bedrock was encountered at 53.7m, compared to a depth of 62.4m in PLS13-098. This represents a significant 8.7m vertical off-set to the top of the basement between holes. A pelitic gneiss was intersected from 53.7m to 176.2m and a semipelitic gneiss from 176.2m to 269.6m. A wide sequence of diabase was intersected from 269.6m to 332.0m. Radioactive mineralization is broad but relatively weak to locally moderate, occurring in several intervals from 0.5m to 23.0m for a total composite of 90.5m over a 160.0m section (82.5m to 242.5m). The difference in intensity of mineralization between holes 098 and 106 may be related to the significant fault interpreted between the 2 holes. Further drilling is required to determine the nature and control of mineralization at the R585E zone.

R585E

R780E Zone

The R780E zone refers to the zone of mineralization currently defined over 60m of strike length between line 750E (hole PLS13-109) and line 810E (PLS13-108). Six additional holes were drilled on the R780E zone since the last update (see news release September 12, 2013), for a total of 12 holes presently defining the R780E zone.

R780E

1155E Region

The 1155E region is located ~210m grid east of the R945E zone. Drilling of two holes (PLS13-090 and 103) was a follow-up test of a subtle radon in water anomaly identified during the Phase 2 EIC Radon In Water and Radon in Sediment Survey Program completed during April 2013, by RadonEx Exploration Management of St. Lazare, QU. This anomaly lies along a ENE trend, parallel to the PL-3B EM conductor and parallel to the 5 separate pods of mineralization thus far identified along a 1.035km trend of uranium mineralization. Although neither drill hole encountered strong mineralization, both encountered significant widths of anomalous radioactivity in a geologic setting similar to the high-grade zones to the west. This leads to encouragement that the mineralized system remains open to the east and that further drilling is required to evaluate the 1155E region.

• Drillhole PLS13-090 was collared as a vertical hole and drilled to a depth of 323.0m. Basement was intersected at 62.0m. A quartzitic gneiss is present from 62.0m to 96.7m. From 96.7m to 314.3m the lithology is comprised of alternating sequences of pelitic / quartzitic / semipelitic units. A diabase unit was encountered from 314.3m to 323.0m (EOH). A weak radioactive mineralized interval is present over a continuous 12.5m interval from 189.5m to 202.0m within a semipelitic gneiss, with a high peak of 1600 cps.
  
  
• Drillhole PLS13-103 was collared as a vertical hole and drilled to a depth of 427.0m. The collar was located 10m south of PLS13-090. Quartzitic gneiss was encountered from 62.4m to 111.7m a quartzitic gneiss, which was underlain by alternating pelitic gneiss, mylonite, and semipelitic gneiss units to 304.6m. From 304.6m to 427.0m (EOH) a semipelitic gneiss dominates. A total composite of 15.5m of radioactive mineralization within a 34.5m section (175.0m to 209.5m) occurs in several weakly radioactive mineralized intervals ranging in width from 1.0m to 6.5m. A deeper and narrow 1.0m weakly radioactive interval is present at 365.5m.
  
  

Line 1155E

A $9.2M, 14,700m drill program and ground geophysics surveys continues at PLS. Barge-based lake drilling is now complete. The program's remaining holes will be land-based.

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. 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.

All holes are planned to be radiometrically surveyed using a Mount Sopris 2GHF-1000 Triple Gamma probe, which allows for more accurate measurements in high grade mineralized zones. The Triple Gamma probe is preferred in zones of high grade mineralization.

Split core samples from the mineralized section of core will be 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. All samples sent for analysis will include a 63 element ICP-OES, uranium by fluorimetry and boron. Assay results will be released when received.
