The Sandpiper marine phosphate project is located offshore from the Namibian coast and is currently in a study stage. It envisages steady-state production of three million tonnes per annum of phosphate rock grading 27-28% P2O5 over an initial mine life of 20 years, including a two-year ramp up period. The output is planned to be used for direct application in agriculture, and for phosphoric acid manufacturing and SSP secondary attack. The phosphate sands and mud will be slurried and pumped via a 27 kilometre pipeline to the process plant site located approximately 6 kilometres inland to the south east of Walvis Bay.
The Sandpiper Project is held by the joint venture company Namibian Marine Phosphate Limited (NMP). NMP is owned by Minemakers (42.5%), UCL Resources Limited (42.5%) and Tungeni Investments (15%). The Feasibility Study capital cost estimate for the Sandpiper Project is US$326.3 million.
