as Hirabeb), with results identifying expansive and deep palaeochannels.

largest of Marenica’s tenements in the Namib Area, has extensive historical exploration mapping, and is
located upstream of the known Aussinanis deposit.
a potentially significant palaeochannel system within the area covered by EPL 7278 (Figure 1). As a
result of this information, a number of HLEM survey lines were undertaken in order to investigate and
confirm the location of palaeochannels within the Hirabeb license.
and deeper, incised, palaeochannels within the area. In general, the depth of the calcrete material is
greater than 10 metres, with the identified palaeochannels reaching depths of greater than 30 metres in
a number of places. In comparison, palaeochannels with maximum depths of between 15 and 18 metres
were recorded in the Koppies palaeochannel system.
