Radio Property Location in Relation to Surrounding Uranium Deposits

IsoEnergy holds an option to earn an initial 70%-interest in the Radio project in the eastern Athabasca Basin contiguous with Rio Tinto's Roughrider deposit (Rio Tinto bought Hathor Exploration in 2012 for $654 million). The Company can earn the 70%-interest by spending an aggregate of $10 million in exploration expenditures by May 31, 2017.

Only one campaign of drilling has ever been completed on the Radio project. NexGen Energy drilled a total of nine holes (totaling 3,472.9 metres) during the summer of 2013 and identified clay alteration, structural disruption in the Athabasca sandstone and alteration and structures in the basement rocks. These features are known to occur at or in the vicinity of high-grade uranium mineralization in the Athabasca Basin.

Radio Property Regional Magnetics and Target Areas

The target areas and drill site locations were defined using a combination of airborne magnetic and VTEM electromagnetic surveys completed in 2011, and ground resistivity and gravity work completed in 2012. The target areas were resistivity and gravity lows coincident with basement structures interpreted from magnetic surveys and weakly conductive basement lithologies defined by the VTEM survey.
