Tenement EPL 6987 (called Koppies) is the first of Marenica’s recently acquired, strategically located, tenements in the Namib Desert region of Namibia, to be explored. Several exploration drilling programs have been completed at Koppies with excellent results achieved.
- Drilling has identified exceptional uranium mineralisation, with the best intersections including:
- KP001 6m at 342ppm U3O8 from 8m
- KP002 3m at 342ppm U3O8 from 8m
- KP004 6m at 432ppm U3O8 from 7m
- KP005 5m at 351ppm U3O8 from 6m
- KP012 7m at 277 ppm U3O8 from 10m
- KP055 13 m at 905 ppm U3O8 from 3m
- Including 2 m at 4,504 ppm U3O8
- KP045 10m at 687 ppm U3O8 from 2m
- Including 2 m at 1,974 ppm U3O8
- KP047 5m at 194 ppm U3O8 from 5m and 2m at 593 ppm U3O8 from 15m
- KP045 10m at 687 ppm U3O8 from 2m
- Results confirm mineralisation in shallow drill holes, less than 20 m in depth
- Koppies 2 palaeochannel is up to 1.2 km wide in places and at least 3.6 km in length
- Mineralisation is calcrete hosted within palaeochannels, the same style of ore used to develop Marenica’s U-pgradeTM uranium beneficiation process. For more information refer to the U-pgradeTM page of our website.
The location of Koppies relative to Marenica’s other EPL’s and nearby known calcrete deposits, is shown in Figure 1 following.
The drilling locations to date at Koppies are shown in Figure 2 following.

The exceptional interval of 2 m at 4,504 ppm U3O8 is contained within an intersection of 13 m at 905 ppm U3O8 from 3 m in hole KP055. The direction of the palaeochannel in the Koppies 1 area is yet to be established.
The best Koppies 2 hole, KP045, intersected 10 m at 687 ppm U3O8 from 2 m, and included 2 m at 1,974 ppm U3O8 from 5 m. The uranium grades were also high in the eastern end of the channel, 5 m at 194 ppm U3O8 and 2 m at 593 ppm U3O8 in KP047.
The Koppies 2 palaeochannel is up to 1.2 km wide and runs the full width of the EPL, approximately 3.6 km in this area. The significance of the channel width, is that the wider the mineralised palaeochannel the greater number of potential contained uranium pounds in any given length.
The Koppies 2 palaeochannel flows westwards from Marenica’s EPL 7279. This discovery at Koppies 2 increases the potential for mineralisation in EPL 7279.
The drill hole locations and the palaeochannel at Koppies 2 are shown in Figure 3.

The identification of multiple mineralised channels emphasises the encouraging exploration potential of the extensive, uranium-fertile palaeochannel system which is Koppies. Future drilling will be aimed at defining the extent of the mineralised system at Koppies.
All palaeochannels identified by drilling to date are mineralised, demonstrating that the area is prospective for calcrete hosted uranium deposits. The approach used to date will form the basis of the planned future exploration work.
Marenica’s drilling campaigns at Koppies follow the Company’s strategy to acquire a significant contiguous strategic package of exploration tenements in the Namib desert, following geological interpretation of regional uranium deposition.
Mineralisation identified within the palaeochannels is calcrete hosted uranium, the same style of ore used to develop Marenica’s U-pgradeTM uranium beneficiation process. The Company, is therefore, confident that based on the results of the Marenica Uranium Scoping Study, U-pgradeTM could be successfully applied if mining and processing operations were developed at Koppies, for a consequent significant reduction in development costs compared to Marenica’s peers with similar grade ores in Namibia.
