FISSION FOCUSES ON RESOURCE EXPANSION AND PROJECT DE-RISKING WITH 43-HOLE DRILL PROGRAM
Fission Uranium Corp. has released drilling plans for 2021, which include a 43-hole (12,640 metres) program at its PLS property -- host to the large, high-grade and near-surface Triple R deposit -- in Saskatchewan, Canada. The fully financed program aims to increase the indicated classified resource of the Triple R deposit's R780E zone, and also upgrade to indicated the large R840W zone, located on land, about 500 metres west of Patterson Lake. The R840W zone is at present substantially drilled to inferred classification, and thus not currently included in the resource used in the prefeasibility study. The winter program will focus on the R780E drilling, while the summer program will focus on the R840W drilling. Fission is planning to advance the PLS project with a feasibility study beginning in 2021 and the success of the planned drill program has the potential to increase the resource used in that study.
Drill program highlights
Resource indicated expansion: R780E zone (winter 2021):
Drilling expected to commence Q1 2021;
20 holes planned (7,200 m);
Drilling to focus on the eastern portion of the R780E, between lines 900E and 1125E, where a large portion of the mineralization is presently classified as inferred and the potential to intersect multiple stacked zones is high;
Drilling to include both infill and stepouts from known mineralization and at a spacing of about 15 m by 20 m (horizontal/vertical) to allow for conversion from inferred to indicated. Drill holes on and around line 900E have the potential to intersect the projected plunge of the high-grade core at R780E.
Resource indicated expansion: R840W zone (summer 2021):
Drilling expected to be completed in Q3 2021;
23 holes planned (5,440 m);
The R840W zone located about 500 m west of Patterson Lake. It is the second-largest of the mineralized zones after the R780E zone and due to its predominantly inferred resource categorization, is not included in the prefeasibility resource;
At a cut-off of 0.25 per cent triuranium octoxide (U3O8) the R840W has a resource estimate of:
- Indicated: 3.3 million pounds U3O8 at 1.68 per cent U3O8 in 88,000 tonnes;
Inferred: 11.5 million pounds U3O8 at 1.86 per cent U3O8 in 280,000 tonnes;
Infill drilling to result in intersection spacing of about 15 m by 20 m (horizontal/vertical), between holes, which has the potential to convert the majority of the R840W zone to indicated category and thus the potential to be included in the feasibility study resource.
Ross McElroy, chief executive officer for Fission, commented: "As we plan to advance the PLS high-grade uranium project to a feasibility study, one of our key goals is to maximize the size and quality of the Triple R deposit. This drill program is therefore designed to potentially expand the resource that can be used in the feasibility study, while also further derisking the project as a whole. Of note, this program has the potential to allow for the inclusion of the R840W zone in the feasibility resource and mine plan."
Drill program technical details
R780E winter 2021 infill drilling
At a cut-off of 0.25 per cent U3O8, the R780E zone has an inferred resource of 10.1 million pounds U3O8 in 549,000 tonnes. A large portion of this inferred resource is situated east of line 900E between a vertical depth of 200 m to 350 m below surface in the hangingwall and footwall of the mineralized zone. This area is prioritized for the winter drill campaign of infill and stepout drilling.
Twenty holes in 7,200 m will target lenses between lines 900E and 1125E, ensuring intersection spacing is less than 15 m by 20 m (horizontal/vertical), which is required for indicated classification. Drilling in this area has the additional benefit of intersecting multiple, stacked, subvertical mineralized lenses, which allows for multiple intersections with a single drill hole.
The R780E zone will be drilled on the lake ice during the winter. The PLS campsite is currently being set up to accommodate the winter program, and ice preparation on Patterson Lake is under way. Precollaring of drill holes is expected to commence early February and coring expected to start by mid-February.
R840W summer 2021 infill drilling
At a cut-off of 0.25 per cent U3O8, the R840W zone has an indicated resource of 3.3 million pounds U3O8 at 1.68 per cent U3O8 in 88,000 tonnes and an inferred resource of 11.5 million pounds U3O8 at 1.86 per cent U3O8 in 280,000 tonnes. At present, none of the R840W resource is included in the prefeasibility mine plan. The objective of 2021 infill drilling at R840W is to convert the majority of the mineralization to indicated by drilling mineralized intersections where spacing is less than 15 m by 20 m (horizontal/vertical). This would allow for the possible inclusion of the R840W zone into the resource used for an upcoming feasibility study. The infill drill plan also includes scissor holes and one oblique drill hole, which aim to both infill and validate the current mineralization model.
PLS mineralized trend and 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 about 3.18 km 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 Nov. 5, 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 55 m and 100 m. R1515W is the westernmost of the zones and is drill defined to about 90 m in strike length, about 68 m across strike and about 220 m vertical and where mineralization remains open in several directions. R840W is located about 515 m to the east along strike of R1515W and has a drill-defined strike length of about 430 m. R00E is located about 485 m to the east along strike of R840W and is drill defined to about 115 m 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 50 m. R780E is located about 225 m to the east of R00E and has a drill-defined strike length of about 945 m. R1620E is located about 210 m along strike to the east of R780E and is drill defined to about 185 m in strike length.
The company completed and filed a prefeasibility study on Nov. 7, 2019, titled "Prefeasibility Study on the Patterson Lake South Property Using Underground Mining Methods, Northern Saskatchewan, Canada." The report summarizes the prefeasibility study (UG PFS), which outlines an underground-only mining scenario for PLS, which to date has only considered the R00E and R780E zones. Further work, including additional drilling, may provide sufficient data for future inclusion of the R1515W, R840W and R1620E zones into the feasibility study mine plan.
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 electromagnetic (EM) conductor.
Patterson Lake South property
The 31,039-hectare PLS project is 100 per cent owned and operated by Fission Uranium. 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 50 km to the north, currently under active exploration and development.
