Hole LE20-51 returned 14.5% U 3 O 8 over 7.5 metres, including 30.9% over 3.6 metres. The most recent holes include LE20-52 that averaged 22.7% over 7.5 metres from 318.5 to 326.0 metres, includ - ing 67.2% over 2.5 metres from 322.5 to 325.0 metres. Hole LE20-53 returned 11.7% over 10.5 metres from 317.5 to 328.0 metres, including 40.4% U 3 O 8 over 3.0 metres from 324.5 to 327.5 metres. The deposit is open is most directions. A summer drilling program is being consid- ered to test the extent of the Hurricane Zone. IsoEnergy shareholders include NexGen Energy (52%), Cameco (4%), Orano (2%), and institutional investors (19%). NexGen Energy Ltd. [NXE-TSX; NYSE AMERICAN] is developing one of the world's largest uranium deposits on its Rook 1 property in the Athabasca Basin and is currently in process of feasibility and environmental assessment under the Canadian Environmental Assessment Act 2012 (CEAA). Rook 1 is estimated to contain an Indicated Resource of 256.6 million pounds of uranium oxide contained in 2.89 million tonnes of 4.03% uranium oxide, according to a resource update and prefeasibility study announced on November 5, 2018. The latest estimate includes a high-grade core of 181 million pounds, contained in 0.46 million tonnes, of grade 17.85% uranium oxide. On top of that is an Inferred Resource of 91.7 million pounds of uranium oxide contained in 4.84 million tonnes, grading 0.86% ura - nium oxide, the company has said. The Indicated Resource outlined so far could support annual production of 24.5 million pounds of uranium over a projected mine life-of-nine of years. The prefeasibility study foresees an initial capital cost of $1.25 billion. NexGen has postponed the Feasibility Study and the Environmental Assessment due to the COVID-19 pandemic. Plateau Energy Metals Inc. [PLU- TSXV] is a uranium exploration and development company, which also offers exposure to lithium. The company has a growing lithium and uranium resource at its Falchani Project in Peru, which is located within a huge and relatively unexplored tenement package, covering 910 km2. The lithium resource is unusual as it is hosted in a volcanic tuff, making potential lithium extraction much quicker than brine. Grade is also much higher than average brine grades. Purepoint Uranium Group Inc. [PTU- TSXV] is focused on the exploration of its nine projects in the Canadian Athabasca Basin. Its flagship Hook Lake Project is owned jointly by Cameco (39.5%), Orano Canada (39.5%) and Purepoint (21%) as operator. It consists of nine claims, cover - ing 28,598 hectares and is situated in the URANIUM URANIUM continued on pag 68 IsoEnergy is led by a team with a track record of success in uranium exploration, development and operations. The Company was founded and is supported by the team at its major shareholder NexGen Energy Ltd (TSX/NYSE: NXE). Results from our 2020 winter drilling program include hole LE20-34 which intersected 8.5 m of uranium mineralization that averages 33.9% U 3 O 8 from 326.0 to 334.5 m, including 5.0 m of 57.1% U 3 O 8 . The Athabasca Basin is home to the largest and highest-grade uranium mines in the world and is consistently a top-rated mining jurisdiction by the Fraser Institute.
