Including 11.5 metres of continuous off-scale radioactivity (greater than 9,999 counts per second); - The sum of discrete intervals of off-scale radioactivity total 13.89 metres;
- Greater than 26 per cent of the interval measure off scale.
- Located 15 metres grid east of PLS13-038 (see news release dated Feb. 19, 2013), in which mineralization was found over 57.5 metres, 11.65 metres of which was off scale.
In additional delineation drilling in the R390E area, PLS13-044 drilled 10 metres north of PLS13-038 intersected a total 34 metres of mineralization in four discrete zones of weak to moderate, and locally strong mineralization, including a narrow (0.1-metre) interval of off-scale radioactivity totalling three metres.
Ross McElroy, president, chief operating officer and chief geologist for Fission, commented: "PLS13-051 extends the strike length of R390E's broad zone of mineralization, which includes significant amounts of off-scale radioactivity, initially discovered in PLS13-038 15 metres to the west. We are focusing our efforts to define this area as we target drilling around these holes that have returned such excellent results."
R390E zone
The R390E zone refers to the zone of mineralization located approximately 390 metres on strike to the east of R00E and first encountered in PLS13-038 (see news release Feb. 19, 2013). R390E has now been delineated with four drill holes (PLS13-038, -044, -046 and -051) and is open in all directions. Based on various geophysical interpretations, including airborne and ground electromagnetic (EM) and ground resistivity surveys, the general target area is on strike of the western mineralization located approximately 390 metres to the west. As is the case with the R00E zone, R390E mineralization is spatially located proximal to the north of the PL-3B basement EM conductor and situated within a well-defined resistivity low corridor. R390E was targeted to test a coincidental radon-in-water and sediment anomaly along this trend, as mentioned in the Feb. 19, 2013 news release. Drill hole interpretation thus far defines the area of mineralization to be associated with a steeply dipping pelitic (plus/minus graphitic) lithology sandwiched between a semipelitic gneiss to the north and a quartz-feldspar gneiss to the south, where the mineralization is focused primarily near the contact between the pelitic gneiss and quartz-feldspar gneiss.
Line 405E
Hole PLS13-051 was a vertical hole collared 15 metres east of hole PLS13-038. A thin interval of Devonian sandstone was encountered from 48.2 metres to 51.6 metres, with basement quartz-feldspar gneiss encountered directly below. A four-metre interval of weak mineralization was intersected from 76 metres to 80 metres, with maximum radioactivity of 1,600 counts per second. The main mineralized horizon was encountered from 95 metres to 148 metres and is associated with the transition from a quartz-feldspar gneiss above to a pelitic gneiss below. The main interval is characterized by moderate to strong radioactivity throughout, with multiple discrete intervals of intense off-scale radioactivity, measuring 13.89 metres of off-scale radioactivity throughout. An 11.5-metre interval (107 metres to 118.5 metres) measured continuous off-scale mineralization. Uranium mineralization occurs as flecks, blebs, clots, veins, semi-massive and wormhole style.
Line 390E
Holes PLS13-044 and -046 were both vertical holes drilled 10 metres north of PLS13-038 and 10 metres south, respectively. In both holes, a thin layer of Devonian sandstone was encountered above the basement lithology. Mineralization was encountered in both holes, with hole PLS13-044 having much better defined mineralization than -046. The main mineralization in hole PLS13-044 was intersected over a moderate to locally strong, 12-metre-wide interval from 77 metres to 89 metres, which included a 0.1-metre interval of off-scale radioactivity. Hole PLS13-046 drilled 10 metres to the south of hole 38 was weakly mineralized over several narrow intervals.

Regional drill holes
Drill holes PLS13-040 and -042 were both targeted on an EM conductor and coincident intense resistivity low located approximately two kilometres to 2.2 kilometres to the east of R00E.
Hole PLS13-040, a vertical hole, was drilled approximately 2.2 kilometres to the east along strike of R00E. Bedrock was encountered at 54.5 metres and consisted of primarily semipelitic and pelitic gneiss (locally graphitic from 86.9 metres to 97.3 metres) to 109.5 metres. A possible mafic rock was encountered from 109.5 metres to the end of hole (182 metres). Significant clay alteration was present over several intervals from 54.5 metres to 109.5 metres, including an interval of sulphide (pyrite) mineralization from 89 metres to 97.3 metres. No anomalous radioactivity was encountered.
Hole PLS13-042, a vertical hole, was drilled approximately two kilometres east of R00E. Bedrock was encountered at 45 metres and consists of alternating sequences of semipelitic and pelitic gneiss (locally graphitic) to the end of hole at 203.4 metres. Moderate to strong chlorite alteration is present from the top of the basement to 121.2 metres. From 121.2 metres to 200 metres, alternating sequences of moderate to strong chlorite alteration and sulphide mineralization are present throughout. No anomalous radioactivity was encountered.

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 a Mount Sopris 2GHF-1000 Triple Gamma probe. 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 are yet to be determined.
An ongoing field program is in progress. This includes approximately 8,000m of core drilling to further delineate and define the mineralized region identified during the summer 2012 program. As well, a Moving Loop Time Domain Electro-Magnetic survey (MLTDEM) was completed on this trend to assist in resolving the geophysical conductors and interpretive structural information. This survey will be used to identify prospective drill targets in the immediate area of mineralization and further along strike.
All holes are planned to be radiometrically surveyed using a Mount Sopris 2GHF-1000 Triple Gamma probe, which allows for 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.
