IsoEnergy Ltd. announced that it has commenced a program of follow-up core drilling targeting extensions of the newly discovered Hurricane zone uranium mineralization at its 100% owned Larocque East property in the Eastern Athabasca Basin of Saskatchewan. Drilling Program Mobilization Highlights: 23 kilometres of winter road have been established; A fully winterized work camp has been erected one kilometre from the drill site; Drilling has begun with the collaring of drill hole LE19-02. The planned drilling program consists of 4,500 metres of core drilling in ten drill holes designed to follow-up discovery hole LE18-01A, the last hole drilled in the summer 2018 drilling program. An8.5-metre-long interval of uranium mineralizationin LE18-01Aaverages 1.26% U3O8 (above a cutoff of 0.1% U3O8) and includes a zone of off-scale radioactivity (>15,000 cps on an SRAT SPP2 scintillometer (the "SPP2")) that averages 6.45% U3O8 over 1.0 metre. Figure 1 shows the location of the Larocque East property and the Hurricane zone. A 23-kilometre-long winter road has been established from the Athabasca seasonal road that connects Points North Landing and Stony Rapids. The winter road has allowed the construction of a fully-winterized and scaleable temporary work camp that is located approximately one kilometre from the drill site.
