Fission Confirms High-Grades at 1515W Zone and Mineralized Area 120m West of New Zone

Assays confirm high grade mineralization at new, western-most zone of the Athabasca Basin’s largest lateral trend

FISSION URANIUM CORP. ("Fission" or “the Company" - http://www.commodity-tv.net/c/search_adv/?v=297377) is pleased to announce the final assays of the winter program, including results that confirm high-grade mineralization at the new R1515W zone at its PLS property, host to the Triple R deposit, in Canada's Athabasca Basin region. Six of eight holes at R1515W zone were mineralized, with four returning multiple high-grade intervals, including hole PLS17-557 (line 1530W), which returned 3.12% U3O8 over 8.5m in 1.24% U3O8 over 27.5m and 5.15% U3O8 over 2.0m in 1.71% U3O8 over 9.0m. R1515W, which was discovered during the winter program, is the western-most zone on the 3.17km mineralized trend and is one of three high-grade zones at PLS that may be added to the updated resource estimate planned within the next 12 months.

Additional Mineralization 120m West of R1515W:  Exploration drilling, which targeted the Patterson Lake Corridor a further 120m west of the R1515W zone, was also very encouraging – returning 0.74% U3O8 over a 0.5m interval in PLS17-514 (line 1665W). Importantly, this signals that the corridor continues to be very prospective for hosting high-grade uranium further along trend to the west towards the high-grade boulder field.

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

“These final assays confirm robust, high-grade mineralization at the new R1515W zone we discovered this winter, as well as continued growth on the R840W and the R780E to R1620E gap area. We are also excited by the mineralization we encountered another 120m west of the new R1515W zone and it is expected that part of our summer drilling program will continue pushing west toward the high-grade boulder field, which lies 3km west of the R1515W zone.”

Composited % U3O8 mineralized intervals are summarized in Tables 1 to 4. Samples from the drill core are split in half sections on site. Where possible, samples are standardized at 0.5m down-hole intervals. One-half of the split sample is sent to SRC Geoanalytical Laboratories (an SCC ISO/IEC 17025: 2005 Accredited Facility) in Saskatoon, SK for analysis which includes U3O8 (wt %) and fire assay for gold, while the other half remains on site for reference. All analysis includes a 63 element ICP-OES, uranium by fluorimetry and boron. Individual zone wireframe models constructed from assay data and used in the resource estimate indicate that both the R780E and R00E zones have a complex geometry controlled by and parallel to steeply south-dipping lithological boundaries as well as a preferential sub-horizontal orientation. Similar geometrical relationships appear to be the case with the R840W and R1620E zones as well.  All depth measurements reported, including sample and interval widths are down-hole, core interval measurements and true thickness are yet to be determined.

PLS Mineralized Trend & Triple R Deposit Summary

Uranium mineralization at PLS occurs within the Patterson Lake Conductive Corridor and has been traced by core drilling approximately 3.17km of east-west strike length in five separated mineralized "zones". From west to east, these zones are: R1515W, R840W, R00E, R780E and R1620E. Thus far only the R00E and R780E have been included in the Triple R deposit resource estimate, where-as the R840W and R1620E zones and the recent addition of the R1515W zone, fall outside of the current resource estimate window.

The discovery hole of what is now referred to as the Triple R uranium deposit was announced on November 05, 2012 with drill hole PLS12-022, from what is considered part of the R00E zone. Through successful exploration programs completed to date, it has evolved into a large, near surface, basement hosted, structurally controlled high-grade uranium deposit.

The Triple R deposit consists of the R00E zone on the western side and the much larger R780E zone further on strike to the east. Within the deposit, the R00E and R780E zones have an overall combined strike length validated by a resource estimate of approximately 1.05km with the R00E measuring approximately 105m in strike length and the R780E zones measuring approximately 945m in strike length. A 225m gap separates the R00E zone to the west and the R780E zones to the east, though sporadic narrow, weakly mineralized intervals from drill holes within this gap suggest the potential for further significant mineralization in this area. The R780E zone is located beneath Patterson Lake which is approximately six metres deep in the area of the deposit. The entire Triple R deposit is covered by approximately 50m to 60m of overburden.

Mineralization remains open along strike in both the western and eastern directions. Basement rocks within the mineralized trend are identified primarily as mafic volcanic rocks with varying degrees of alteration. Mineralization is both located within and associated with mafic volcanic intrusives with varying degrees of silicification, metasomatic mineral assemblages and hydrothermal graphite. The graphitic sequences are, associated with the PL-3B basement Electro-Magnetic (EM) Conductor.  The R840W zone, located 495m west along strike of the Triple R deposit, now has a defined strike length of 465m and is still open. Drill results within the R840W zone have significantly upgraded the prospectivity of these areas for further growth of the PLS resource on land to the west of the Triple R deposit. The recent discovery of high-grade mineralization further to the west on line 1515W (R1515W zone), located 510m to the west along strike of the R840W zone, has significantly upgraded the prospectivity for further growth to the west along the Patterson Lake Corridor. The recently discovered high-grade mineralization in the R1620E zone, located 210m to the east along strike has significantly upgraded the prospectivity for further growth of the PLS resource to the east of the Triple R deposit.
