Debmarine Namibia

Marine mining has surpassed land based mining in yearly production in Namibia

Debmarine Namibia, which operates in Namibia’s Atlantic coastal waters, is part of a 50/50 joint venture between Namibia and De Beers, and is the world’s leader in diamond mining at sea.

Namibia has the richest known marine diamond deposits in the world, estimated at more than 80 million carats - representing approximately 90% of the country’s diamond resources.  Debmarine Namibia recovers approximately 1 million carats every year from the sea floor, accounting for more than half of Namdeb's total diamond production.

Our specialist fleet

We operate a fleet of five mining vessels (mv) that we think of as floating mines, capable of retrieving diamond-bearing materials from the seabed and processing them to a diamond rich concentrate. They include:

  • mv Debmar Atlantic
  • mv Debmar Pacific
  • mv !Gariep
  • mv. Peace in Africa
  • mv. Grand Banks


Our special environment

Unlike land-based mining operations, which include end-of-life planning for environmental restoration, rehabilitation of the seabed and the marine environment occurs naturally over time. Our environmental team oversees strict guidelines for the vessels – covering everything from how we mine to how we dispose of every single piece of waste produced on a vessel.  By monitoring changes to the environment over time, we’re able to build-up a greater knowledge of the natural variability of the environment and the impact of marine mining.
