Fission Uranium begins drilling PLS project

2023-05-31 07:06 ET - News Release

Mr. Ross McElroy reports

FISSION COMMENCES SUMMER DRILLING; ADVANCES FRONT END ENGINEERING DESIGN AT PLS

Fission Uranium Corp. has commenced a two-stage drill program as part of the front-end engineering design (FEED) at its PLS high-grade uranium project in Saskatchewan, Canada. A total of 12 holes will be drilled. Two holes will gather geotechnical data for underground mine infrastructure, and 10 holes will gather hydrogeological data to further optimize the design of the proposed tailings management facility. This program encompasses all remaining drilling required to complete the FEED. Fission is in the process of selecting a lead engineering consultant to head up this important engineering design stage.

News highlights

  • Two-stage, 12-hole drill program has commenced at PLS, gathering engineering data for mine infrastructure and facilities.
  • Drilling data will be used to increase technical understanding of hydrogeological and geotechnical conditions.
  • Development on schedule through the permitting phase toward a construction decision.

Ross McElroy, president and chief executive officer for Fission, commented: "Development work at Fission Uranium's PLS project continues to gain pace. With this program we will have all the necessary drilling data to complete the important front-end engineering design for the proposed mine infrastructure and facilities. The results will also potentially enable us to further optimize the mine plan and reduce long-term costs."

Technical details

Geotechnical drilling (two holes for a total of 440 metres). Purpose is to confirm geotechnical parameters of the rock mass and discontinuities, specifically in the pillar between the fresh air shaft and the R840W access drifts, and in the area of the return drift near the exhaust air shaft. The data will enable informed mine planning of the UG mine infrastructure per the feasibility study (FS) geotechnical recommendations.

Hydrogeological drilling (seven test holes and three monitoring holes for a total of 500 m). The purpose is to assess the potential for extending the tailings management facility (TMF) northward into the aggregate borrow pit. If the results support this goal, it will allow the TMF to accommodate a greater tailings volume than the FS design considered, or to reduce the ultimate berm height of the TMF if the FS design volume is maintained. Either option will reduce long-term rehabilitation costs, and provide operational flexibility and cost-efficiency.

Following the drill program, routine laboratory testwork will be conducted by mine engineering specialists, Clifton Group -- an award-winning engineering and environmental consultancy -- and BGC Engineering.

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 kilometres 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 the 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 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.

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 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.
