Namibian Marine Phosphate


Namibian Marine Phosphate (Pty) Limited (NMP) is a joint venture company owned 85% by Mawarid Mining LLC through its 100% owned Namibian registered subsidiary companies and 15% by Namibian registered Havana Investments (Pty) Limited (Havana).

Namibian Marine Phosphate (Pty) Ltd (NMP) is developing what could potentially become the world’s first marine phosphate mine off the coast of Namibia. This will establish Namibia as a premier rock phosphate producer, contributing to the Namibian economy and supporting on going crop production through the provision of phosphorus for fertiliser, as well as creating new knowledge associated with fertilizer and other products derived from phosphates.

The NMP project is known as the Sandpiper Project. The deposit lies about 120 km from Walvis Bay. The intention is to produce 3 mtpa (million tonnesper annum) of phosphate concentrate within three years of start-up.

The Resource

Exploration and resource development completed to date confirms the Sandpiper Project has a defined mineral resource inventory of 1.8 billion tonnes (dry) at 19.05% P 2O5 using a 15% cut off grade.


Current dredging technology allows recovery from depths of upto 165m. Dredging contractors, Jan de Nul estimate that a purpose built extended dredgingarm, requiring limited modification of their largest dredge, the Cristobal Colon, will allow recovery from 225 m depth.


Ore is dredged from the ocean floor, pumpe dashore, wet-screened to remove shellsand the resulting slurry pumped to the beneficiation plant-site near Walvis Bay. After upgrading the concentrate to 27.5% P2O5 (phosphate), it is dried and stored. Initially, the concentrate is trucked to Walvis Bay Port for export. Later, although several options are being studied, it is like lythata pipe-belt conveyor will deliver the product to the port.
