IsoEnergy Intersects Second Elevated Radioactivity at Geiger Property

- March 13th, 2018

IsoEnergy Ltd. announced that it has intersected a second zone of elevated radioactivity during a core drilling program at its Geiger property

IsoEnergy Ltd. (TSXV:ISO) announced that it has intersected a second zone of elevated radioactivity during a core drilling program at its  Geiger property in the Eastern Athabasca Basin region of Saskatchewan.

As quoted in the press release:

The additional zone of elevated radioactivity has been intersected in drill hole GG18-09.  GG18-09 is located 1.7 kilometres southwest of drill hole GG18-08, which recently intersected a zone of elevated radioactivity reported in a news release dated March 5, 2018.  Figure 1 shows the location of both drill holes on the Geiger property.  The elevated radioactivity in GG18-09 is relatively thick and straddles the sub-Athabasca unconformity.  Radioactivity measured with a 2PGA-1000 total gamma down-hole probe averages 1,370 counts per second (CPS) over 19.3 metres from 203.1-222.4 metres.  The maximum probe value within the interval is just over 7,300 CPS.  Figure 2 is a cross-section showing the location of the mineralization relative to the interpreted geology.  The zone of elevated radioactivity is associated with well-developed and locally massive clay alteration and significant core loss.  Analysis of the recovered 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 GG18-09 is a 50 metre step-out (along strike to the southwest) from historic mineralized drill hole HL-50.  HL-50 intersected 2.7% U3O8 over 1.2 metres in basement gneiss just beneath the base of the Athabasca sandstone.  The closest drill hole along-strike to the southwest is located 150 metres to the southwest, and likely missed the target horizon given the reported basement geology.  Therefore, the mineralized zone is wide open to the southwest and at depth.  With the completion of drill hole GG18-09, the winter drilling program at Geiger is now complete.  A summer core drilling program to follow up on the results in drill holes GG18-08 and GG18-09 is being planned.

Craig Parry, CEO, commented:

I’m very pleased with the results from IsoEnergy’s maiden drilling program on the Geiger property, which was only acquired late last year.  With two zones of elevated radioactivity and strong alteration which is open in several directions, follow-up drilling during the summer season is clearly warranted on the property.
