About the Carter Lake Uranium Project

The Carter Lake Project lies near the eastern edge of the Clearwater Domain, ~21km northeast of the Patterson Lake property, which has a reported NI 43-101 resource estimate of total of 2,011,000 tonnes of 1.83% U3O8 containing 81,111,000 pounds of U3O8 including the R780E High Grade Zone estimated to contain 45,079,000 pounds U3O8 @ 18.22% U3O8 and an inferred Mineral Resources are estimated to total 785,000 tonnes @ 1.57% U3O8 containing 27,157,000 pounds of U3O8 including the R780E High Grade Zone estimated to contain 13,898,000 pounds U3O8 @ 25.06% U3O8. (Fission Uranium Corp. PEA September 14, 2015.) Nexgen Energy has reported (March 31, 2017) that the Arrow Deposit's Mineral Resource comprises an Indicated Mineral Resource of 179.5 M lbs of U3O8 within 1.18M tonnes grading 6.88% U3O8, and an Inferred Mineral Resource of 122.1 M lbs of U3O8 contained within 4.25 M tonnes grading 1.30% U3O8.

The Carter Lake Project, which borders Purepoint/Cameco/AREVA's Hook Lake Project to the east, has basement depths estimated at between 400-500m, within the general discovery range of the McArthur River mine. The principal exploration target at Carter Lake is ~4.7km of subsurface conductive anomalies, identified in a 2006 MegaTEM survey and a 2008 VTEM survey, both completed by ESO Uranium Corp. The anomalies are interpreted as a conductive horizon, at or above the unconformity and which may be indicative of hydrothermal enrichment.
