Athabasca Basin Setting


▷ Sandstone-hosted deposits (egress type) tend to have mining challenges due to the fact the mineralization is ‘perched’ within the unconsolidated and wet Athabasca Sandstone unit.

▷ Arrow is a basement-hosted zone (ingress type) which is analogous to Cameco’s Eagle Point mine.

Uranium - Demand


▷ China represents the fastest growing demand for nuclear anywhere in World in three decades.

▷ Chinahas26reactorsoperating,25underconstruction,43plannedand136proposedversusthecurrentglobalreactor fleetof394.

▷ China’sgoalof58GWby2020and150GWby2030.

WorldNuclearAssociation,RaymondJamesLtd.

Uranium - Supply


▷ 90% of global mine supply under severe technical or sovereign risk.

▷ Saskatchewanranked#2bestminingjurisdictionbyFraserInstitutein2015,but2of3operatingminesunderseveretechnical risk.

▷ Highconcentrationofsupplywithtop10minesaccountingfor+50%ofannualuraniumproduction.

WorldNuclearAssociation,RaymondJamesLtd.

Uranium - Outlook

nexgenenergy.com|TSX-V:NXE|JANUARY201624 WorldNuclearAssociation,RaymondJamesLtd.

▷ Demand is expected to outpace total uranium supply by 2018 whereby nuclear utilities will have to either turn off reactors (challenging and expensive) or pay higher prices for nuclear feed.
