Over the last 40 years the Erongo Region of Namibia has produced in excess of 300Mlb of yellowcake and still contains 1.5Bnlb of U3O8 in Measured and Indicated Resource categories and 350Mlb in Inferred Resources. These all occur within a 50km radius and include Deep Yellow Limited’s (DYL) projects. The uranium mineralisation occurs in two distinct types of geological environment:
Alaskite-type uranium mineralisation which is currently mined at Rössing and Husab. This type occurs in granitic and associated rocks of the Damaran or Pan-African orogenic belt forming the basement of the region.
Palaeochannel/calcrete type uranium mineralisation which occurs in Tertiary and Quaternary sediments filling ancient river valleys that drained the uranium rich hinterland.
Reptile Mineral Resources and Exploration (Pty) Ltd (RMR), a wholly owned subsidiary of DYL, manages the Reptile Project, the Nova Joint Venture and the Yellow Dune Joint Venture covering 1,983km2. These projects contain resources totalling 126Mlb at 321ppm in the Measured, Indicated and Inferred categories at cut-offs varying between 100ppm and 250ppm U3O8. Specifically:
The Reptile project includes two EPLs covering three alaskite type resources totalling 45Mlb at 420ppm U3O8 and four palaeochannel/calcrete resources totalling 63Mlb at 301ppm U3O8. There are also several exploration targets of both palaeochannel/calcrete and alaskite – type.
The Yellow Dune JV includes one MDRL application covering a drilled-out uranium resource of the palaeochannel/calcrete type totalling 18Mlb U3O8 at 237ppm
The Nova JV includes two EPLs prospective for both alaskite and palaeochannel/calcrete type uranium mineralisation.
