The new mining vessel will increase production to over 300 000 carats per year, making Namco the world’s second largest marine diamond miner, as well as Africa’s second largest producer. However, ongoing teething problems with the new seabed crawler resulted in the unit being damaged – and as a result, Namco has had to arrange financing in order to avoid liquidation.

This map shows the current DFI marine concessions off the coast of Luderitz Namibia. The established resource of 1.1 million carats exists in the Marshall Fork, Staple Basin/Conical Beach and Diaz Reef areas. The red dots indicated mineralized samples that formed the data for the 2000 feasibility study.

Diamond mining in Namibia dates back to 1908 when a rail worker accidentally discovered a diamond in an ancient beach terrace at Kolmanskop station near Lüderitz. This discovery sparked a diamond rush and by 1913 the onshore Namibian diamond fields accounted for 20% of world diamond production. By 1920 many of the companies mining in the area were amalgamated by DeBeers into a corporation called Consolidated Diamond Mines (CDM).

The considerable potential of these marine deposits has resulted in rapid advances in marine diamond extraction technology to the stage where marine diamonds represent about 56% of Namibia’s total diamond production. This figure is set to grow, as onshore reserves are gradually depleted. Namdeb is Namibia’s largest diamond producer. Namdeb is an equal partnership with De Beers and the Namibian Government and is responsible for onshore mining operations as well as marine operations.

It is estimated that a total of 100 million carats of 90% gem quality diamonds have been produced from the on shore deposits to date. Mining is still occurring and new deposits are being discovered and put into production in South Africa and Namibia. Marine Diamond Mining Starting as early as 1958, people have been exploring the seabed for alluvial diamonds.
