Summary:

The topography of the Klipspruit area is generally flat to gently sloping, at a mean elevation of approximately 1,600 m. The area drains towards the north. The unconsolidated material that overlies the solid sediments consists of soil, sand, laterite and clay. The thickness of this unconsolidated overburden averages 6 m, but varies depending on the depth of weathering.

Exploration boreholes target the full coal-bearing sequence and terminate in Dwyka Tillite. The sedimentary strata comprises mainly white, fine- to coarse-grained sandstone layers with alternating shale and shaly sandstones with bioturbated layers in places. The No.2 and No.4L Seams are separated by sandy shales grading into medium-grained sandstone towards the top. Coarse grained, hard sandstone layers are present immediately above the No.4L Seam.

Coal seams preserved in the Klipspruit area include No.5, No.4U, No.4L, No.3, No.2 and No.1 Seams. As a result of the topographic surface sloping to the north, all of the coal seams except for No.2 and No.1 Seams have been affected by weathering. This is especially true of the No.5 Seam, which is almost totally lost to erosion north of the Ogies Dyke.

A dolerite dyke has been identified in the Bankfontein area, which has affected Coal Resources mainly in the No.4U Seam. This was the result of deep weathering adjacent to the dyke.

The Ogies Dyke is a well-known post-Karoo intrusive structure that extends for some 70 km in an east-west direction. It forms the southern boundary of the main Klipspruit opencast resource area, and separates it from the Klipspruit South resource area. The dyke varies in thickness from 40 m to 70 m and dips steeply to the south. It does not vertically displace the coal seams.
