news - 510 m step out!!FISSION URANIUM CORP. (FCU.TO)(FCUUF)(2FU.F) ("
Fission" or "
the Company") is pleased to announce that its exploration drilling has resulted in the discovery of a new high-grade zone - R1515W - at its' PLS property, host to the Triple R deposit, in Canada's Athabasca Basin region. The zone is located along the western strike extension of the Patterson Lake Corridor, west of both the Triple R deposit and the R840W zone. The discovery of the new high-grade zone is marked by
hole PLS17-539, which has intersected 32.0m of total composite mineralization, including a 31.0m wide continuously mineralized interval including a total composite of 0.77m of radioactivity >10,000 cps (with a peak of 22,300 cps). The hole is located on line 1515W, approximately 510m west of the western-most mineralized hole on the high-grade, near-surface R840W zone.
Drilling Highlights Include:
- New zone - R1515W - discovered by regional exploration drilling approximately 510m west of the high-grade, near-surface R840W zone
- Western Extension includes 180m of strike length of anomalous radioactivity (1485W to 1515W): 3 additional core holes and 4 reverse circulation "RC" holes intersected anomalous radioactivity associated with hydrothermal alteration between lines 1485W and 1665W including hole PLS17-539 (line 1515W):
- 32.0m total composite mineralization over a 87.5m section (between 134.5m to 222.0m), including
- 31.0m of continuous mineralization (191.0m to 222.0m), including
- 0.77m total composite >10,000 cps
- 32.0m total composite mineralization over a 87.5m section (between 134.5m to 222.0m), including
- 31.0m of continuous mineralization (191.0m to 222.0m), including
- 0.77m total composite >10,000 cps
- 31.0m of continuous mineralization (191.0m to 222.0m), including
- 0.77m total composite >10,000 cps
- 0.77m total composite >10,000 cps
- Expansion of the Athabasca Basin's largest high-grade mineralized trend to 3.14km: Fission has now extended the PLS high-grade mineralized trend from 2.63km to 3.14km, which is larger in strike length than any other mineralized trend in the region
Ross McElroy, President, COO, and Chief Geologist for Fission, commented
"We are thrilled with the discovery of a new zone at PLS along the very prospective Patterson Lake Corridor and with the increase of half a kilometer to the high-grade mineralized trend, which now stands at 3.14km in strike length. This success is the validation of a key objective during the winter drill program: to discover new, shallow and high-grade occurrences on the prolific PLS project. Having successfully encountered anomalous radioactivity with our drilling in a 625m step out from R840W (see news release Feb 27, 2017), and subsequently seeing anomalous radioactivity in several core and RC holes over 180m of strike length, we were confident we were in the right area. With substantial mineralization in hole PLS17-539, we now have confirmation. The next step for this area is to begin growing the zone, just as we have done so successfully with every zone at PLS and we will also continue to pursue our other exploration hot spots on the property."
Western Extension grown to 180m strike length: Exploration drilling of the western extension of the Patterson Lake Corridor during the winter 2017 program to date is comprised of 7 core holes and 6 "RC" holes, including 2 core holes previously reported (PLS17-514 and PLS17-519 on line 1665W reported on Feb 27, 2017). Nine of these holes (5 core holes and 4 RC holes), including PLS17-539, over a 180m strike length between lines 1485W and 1665W, show variable anomalous radioactivity and hydrothermal alteration. These exploration results are very encouraging and now, with a wide mineralized intersection, including high-grade radioactivity, the western extension will continue to be the focus of further testing.
As was the case with the discovery of the R840W zone in 2016, the new zone discovery on line 1515W again proves that Fission's innovative use of lower-cost RC drilling and follow-up core drilling, coupled with a very skilled and motivated exploration team is a recipe for success. The uniquely shallow nature of PLS mineralization makes this a viable exploration approach.

Natural gamma radiation in drill core that is reported in this news release was measured in counts per second (cps) using a hand held RS-121 Scintillometer manufactured by Radiation Solutions, which is capable of discriminating readings to 65,535 cps. Natural gamma radiation in the drill hole survey that is reported in both core and reverse circulation "RC" holes this news release was measured in counts per second (cps) 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. 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 intersection measurements are down-hole. All depths reported of core interval and down-hole gamma measurements including radioactivity and mineralization intervals widths are not always representative of true thickness and true thicknesses are yet to be determined in zones outside of the Triple R deposit. Within the Triple R deposit, 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.
