ISOENERGY INTERSECTS ELEVATED RADIOACTIVITY AT THE GEIGER PROPERTY

IsoEnergy Ltd. has intersected a zone of elevated radioactivity during a continuing core drilling program at its 100-per-cent-owned Geiger property in the eastern Athabasca basin region of Saskatchewan.

A zone of elevated radioactivity has been intersected in drill hole GG18-08. The zone was intersected within basement pelitic gneiss, approximately 15 metres beneath the base of the Athabasca sandstone. Radioactivity measured with a 2PGA-1000 total gamma down-hole probe averages 4,500 counts per second (CPS) over 2.1 metres. The maximum probe value within the interval is just over 14,000 CPS. Analysis of the drill core with a hand-held spectrometer indicates the radioactivity is due to uranium, but geochemical analysis is needed for final confirmation. The drill core has been sampled and geochemical results are pending.

Drill hole GG18-08 is a 50-metre stepout (along strike to the northeast) from historic mineralized drill hole HL-76. HL-76 intersected 0.65 per cent triuranium octoxide over 0.1 metre in basement gneiss approximately 43 metres beneath the base of the Athabasca sandstone. GG18-08 is the farthest hole to the northeast along the northeast-trending HL11S conductor. Therefore, the mineralized zone is wide open to the northeast and at depth. According to historical geophysical surveys, the HL11S conductor might extend up to 2.5 kilometres to the northeast beyond GG18-08. Drill hole GG18-08 is the seventh of an eight-hole program, which should be completed by March 9.
