This study has demonstrated that the technology and raw materials of the early assemblage are distinctive from those recovered from the upper layers.In the early assemblage silcrete and quartzite are common raw materials, and there are also fragments of an edge-ground axe and ground haematite.The sand below this layer was devoid of any signs of human activity.

Below the earliest occupation there was 2 m of sand that were deposited gradually over a period of 110,000 years.More than 1500 artefacts were found in the lowest occupation layer.Artefacts included those made from silcrete, quartzite and white quartz, a grindstone, pieces of dolerite and ground haematite, chlorite and mica and red and yellow ochre.Optical dates were obtained from several stratigraphic levels in an excavation that was 3 m deep where flaked stone artefacts and ground pigments were found in a primary depositional setting.Dates of 53.4 ± 5.4 ka and 60.3 ± 6.7 ka bracket the lowest human occupation levels, and that there is good agreement between optical and C age estimates has been demonstrated by the upper levels.
