• Increased Global Demand for mineral resources• >80% of Global mineral resources beneath the Oceans• Rise in Metal prices combined with development in deep water

technology now make Marine mining feasible• Land Resources becoming scarcer

The Atlantis II Project Is A Technical Challenge• Deposit is located in 2000 meters of water• 70km from nearest shore• New processing and mining technology required• No existing infrastructure • Elevated Brine Pool temperatures 45°C – 62°C• Fine Particle Size Distribution (PSD) of Ore 80% < 2

microns

A Commercial risk• Worlds Deepest mining operation and First deep sea mud

deposit to be mined

Offshore Processing Challenges

• Ore is fine grained sulphide muds

• Pre-Pilot Mining Operations undertaken by Preussag (1980’s) successively concentrated offshore using floatation to 30% Zn @ 70% Recoveries

• New processing techniques using sea water are being developed to achieve recoveries up to 85%

• Filtration using Rotary Vacuum Filters or Disc Nozzle Filters – Slurry Transport
