NexGen's 32.9% owned subsidiary, IsoEnergy ( holds a highly prospective portfolio of uranium exploration projects in the historic eastern Athabasca Basin.

The Company is currently advancing its Larocque East Project in Canada’s Athabasca Basin, which is home to the Hurricane deposit, boasting the world’s highest grade Indicated uranium Mineral Resource. The Company also holds a portfolio of permitted, past-producing conventional uranium and vanadium mines in Utah with a toll milling arrangement in place with Energy Fuels Inc. These mines are currently on stand-by, ready for rapid restart as market conditions permit, positioning IsoEnergy as a near-term uranium producer.

IsoEnergy holds 24 strategically located and prospective assets covering 248,000 hectares in the eastern Athabasca Basin region with Larocque East, Geiger, Thorburn Lake and Radio being the highest priority properties. All projects are 100% owned by IsoEnergy.

The Geiger property hosts high grade basement hosted uranium mineralization of up to 2.74% U3O8 over 1.2 metres and is located within 20 kilometres of the McClean Lake uranium mill.

The Thorburn Lake project is located 7 kilometers east of Cameco's Cigar Lake mine. Uranium has been intersected on the property, including 0.6 metres of 0.43% U3O8 in drill hole TBN-11-05a in basement rocks immediately below the sub-Athabasca unconformity. Numerous geophysical targets remain to be drilled at Thorburn Lake.

The Radio project is located 2 kilometres east (and along strike) of Rio Tinto’s Roughrider uranium deposit. Exploration drilling by IsoEnergy in 2016 and 2017 located a large zone of strong clay alteration with locally elevated uranium geochemistry in basement rocks along the southern boundary of the property. Additional targets warrant drill testing.
