Santé Finance through its subsidiary Gazania Investments 361 (Pty) Ltd purchased a Diver Operated Mining Vessel, MV Nandi that has been fully refurbished.
The mining system is based on one which has been successfully used since the late 1960’s in water depths shallower than 30m. The mining system comprises of a 10” suspended suction hose and an onboard mining pump. The suction hose and mining tool has a ~300 mm internal diameter. The mining tool itself consists of a 300 mm diameter steel pipe fitted with a robust suction hose, which has an opening fitted with grizzly bars to allow sized gravel to pass through and prevent blockages in the suction system. The suction hose is controlled by a diver who directs it to the preferred gravel and will also be fitted with high pressure water jetting nozzles to agitate the gravel on the seabed and improve mining efficiency.
