SnapshotThe group’s plans to sell its 67.2% stake in West Coast Resources (the old De Beers Namaqualand diamond mines) fell through when talks with prospective buyers Kernel Resources were terminated.

This has meant West Coast Resources is not in a position to meet its working capital requirements without it receiving the necessary funding.

Instead of injecting in new working capital, Trans Hex has opted to apply for West Coast Resources to be placed into provisional liquidation.


Namaqualand Diamond Fund Trust 4 % Indirect
Dinoka Investment Holdings (Pty) Ltd 8.8 % Indirect
Trans Hex Group Ltd. 67.2 % Indirect
West Coast Resources (operator) 100 % Direct
West Coast Resources is a diamond-mining company with operations in the Namaqualand region of the Northern Cape. The Company is owned by Trans Hex Group Ltd (67,2%), the State (Department of Public Enterprises) (20,0%), Dinoka Investment Holdings (Pty) Ltd (8,8%) and the Namaqualand Diamond Fund Trust (4,0%).

At an ownership level, the Group has acquired an additional 27,2% shareholding in West Coast Resources (Pty) Ltd on 1 February 2018, effectively securing a majority stake of 67,2% in the company and its Namaqualand operations.

Deposit type

  • Kimberlite


A host of diamond placers of variable age have been deposited on the Namaqualand coastal plain. The source of the diamond populations in these placers were primary diamondiferous kimberlite pipes located on the South African Kaapvaal Craton. Extensive erosion of these kimberlites released the diamonds into fluvial systems that transported them vast distances to the Atlantic coast. A portion of the diamonds were deposited in fluvial deposits of different ages on the coastal plain, however the majority were carried into the marine environment and deposited and reconcentrated in beach terraces. The abrasive fluvial and marine transport mechanisms have, effectively, removed a high percentage of the poorer quality diamonds from the secondary placer deposits, thus providing a diamond population that is 95% gem quality. The active nature of the tectonic framework of the Namaqualand region during the Cretaceous and Tertiary resulted in a complex structural setting that played a major role in the continuously evolving rift-flank drainage pattern adjacent to this area. As a result, the diamond placers on the Namaqualand coastal plain are complex due to continuous reworking of deposited diamondiferous fluvial sediments which resulted in a highly variable suite of placer deposits in terms of mineralisation style and diamond grade (stone density and stone size).

Most of the earliest placer and associated sedimentary deposits have been reworked completely, thus making it difficult to trace a complete stratigraphic history for the diamond placers. However, DBCM has undertaken extensive exploration work on the coastal plain and has identified a substantial range of ages of the deposits from the older Koingnaas fluvial channels (Cretaceous) in the south to the Megalodon type channels (Oligocene) and proto Buffels River sediments (Miocene) and finally the marine terraces of the Buffels Marine Complex (Plio-Pleistocene) in the north.
