  13. Slide 13: Phoenix Geology: Unique uranium deposit with exceptionally high grades

    Phoenix Zone A Phoenix Deposit – Plan View Schematic Cross Section Phoenix Geology: Unique uranium deposit with exceptionally high grades Highlights(1): • Mineralization is situated at or immediately above the unconformity(“UC”) Athabasca Sandstone • Two distinct zones – Phoenix A + B • Approximatel

  14. Slide 14: Phoenix Operation: Application of low-cost ISR mining method to high-grade Athabasca Basin

    Phoenix Operation: Application of low-cost ISR mining method to high-grade Athabasca Basin ISR Mining Process(1): 1. Mining solution (also known as “lixiviant”) is pumped through a permeable orebody via injection well 2. Lixiviant dissolves the 4 uranium as it travels through the orebody 1 5 3. Uran
