Drilling is part of the program to upgrade key areas of the Triple R deposit to indicated classification
KELOWNA, British Columbia, May 23, 2018 (GLOBE NEWSWIRE) -- FISSION URANIUM CORP. ("Fission" or “the Company") is pleased to announce assay results from all six winter program holes drilled on the R780E zone at its’ PLS property, in Canada's Athabasca Basin region. All six holes encountered high-grade intervals. Of particular note is hole PLS18-573 (line 510E), which returned 97.0m of total composite mineralization including multiple high-grade intervals such as 4.0m @ 21.93% U3O8, 3.5m @ 10.95% U3O8 within 25.5m @ 6.36% U3O8, and 1.5m @ 22.36% U3O8 within 10.0m @ 4.14% U3O8, respectively. Importantly, these successful holes are part of a program to upgrade certain key areas of the R780E zone, currently classified as Inferred resources, to Indicated resources.
Ross McElroy, President, COO, and Chief Geologist for Fission, commented,
"These final Winter assays from the Triple R deposit’s central R780E zone highlight the potential to grow the resources contained within the current boundaries of the deposit. As we progress towards pre-feasibility, it is our goal to upgrade key areas of our inferred-category resources to indicated-category. This has the possibility to enhance the economics and further de-risk the project.”
Assay Highlights Include:
PLS18-573 (line 510E): key intervals
- 21.5m @ 0.36% U3O8 (74.0m to 95.5m), including
- 1.0m @ 2.08% U3O8 (76.0m to 77.0m)
- 25.5m @ 6.36% U3O8 (100.0m to 125.5m), including:
- 4.0m @ 21.93% U3O8 (101.0m to 105.0m)
- 3.5m @ 10.95% U3O8 (115.5m to 119.0m)
- 10.0m @ 4.14% U3O8 (131.0m to 141.0m), including:
- 1.5m @ 22.36% U3O8 (133.5m to 135.0m)
PLS17-575 (line 720E): key interval
- 27.5m @ 3.60% U3O8 (135.5m to 163.0m), including
- 7.0m @ 10.70% U3O8 (145.0m to 152.0m)
Table 1: R780E Zone - Composited Mineralized Intervals from Drill Holes
|Az||Dip||From (m)||To (m)||Interval
- Minimum Thickness: 0.50m
- Grade Cut-Off: 0.05 U3O8 (wt%)
- Maximum Internal Dilution: 2.00m
Composited % U3O8 mineralized intervals are summarized in Table 1. 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. All depths reported of core interval measurements including sample and interval widths are down-hole and are not always representative of true thickness. The orientation of the mineralized intervals tend to follow that of lithologic contacts, and generally dip steeply to the south. Within the Triple R deposit, individual zone wireframe models constructed from assay data and used in the resource estimate indicate that all 5 zones have a complex geometry controlled by and parallel to steeply south-dipping lithological boundaries as well as a preferential sub-horizontal orientation.
PLS Mineralized Trend & Triple R Deposit Summary
Uranium mineralization of the Triple R deposit at PLS occurs within the Patterson Lake Conductive Corridor and has been traced by core drilling over ~3.18km of east-west strike length in five separated mineralized "zones" which collectively make up the Triple R deposit. From west to east, these zones are: R1515W, R840W, R00E, R780E and R1620E. Through successful exploration programs completed to date, Triple R has evolved into a large, near surface, basement hosted, structurally controlled high-grade uranium deposit. The discovery hole was announced on November 05, 2012 with drill hole PLS12-022, from what is now referred to as the R00E zone.
The R1515W, R840W and R00E zones make up the western region of the Triple R deposit and are located on land, where overburden thickness is generally between 55m to 100m. R1515W is the western-most of the zones and is drill defined to ~90m in strike-length, ~68m across strike and ~220m vertical and where mineralization remains open in several directions. R840W is located ~515m to the east along strike of R1515W and has a drill defined strike length of ~430m. R00E is located ~485m to the east along strike of R840W and is drill defined to ~115m in strike length. The R780E zone and R1620E zones make up the eastern region of the Triple R deposit. Both zones are located beneath Patterson Lake where water depth is generally less than six metres and overburden thickness is generally about 50m. R780E is located ~225m to the east of R00E and has a drill defined strike length of ~945m. R1620E is located ~210m along strike to the east of R780E, and is drill defined to ~185m in strike length.
Mineralization along the Patterson Lake Corridor trend remains prospective 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.
Patterson Lake South Property
The 31,039 hectare PLS project is 100% owned and operated by Fission Uranium Corp. PLS is accessible by road with primary access from all-weather Highway 955, which runs north to the former Cluff Lake mine and passes through the nearby UEX-Areva Shea Creek discoveries located 50km to the north.
