Earlier this month, Nautilus Minerals unveiled the three seafloor production tools (SPTs) it will be using for its first deep sea mining project. The machines, built by Newcastle-based subsea robotics manufacturer Soil Machine Dynamics (SMD), have passed factory testing and are scheduled for shallow water testing in early 2016.

• Deep-sea mining is the process of retrieving mineral deposits from the deep sea – the area of the ocean below 200 m. • Depleting terrestrial deposits and rising demand for metals are stimulating interest in the deep sea, with commercial mining imminent. • The scraping of the sea floor and pollution from mining processes can wipe out entire species – many yet to be discovered.

Deep seabed mining (DSM) is the term applied to processes and technologies designed to collect metal-rich resources from the deep seafloor. There are three types of deep seabed mineral resources that are of interest to mining companies: seafloor massive sulphides, cobalt-rich ferromanganese crusts, and polymetallic nodules.

Subsea mining, or deep sea mining, is a method of retrieving minerals from the ocean floor. Deepsea mining operations typically occur at depths of 4500 ft. to 12,000 ft. around areas with metallic nodules, as well as areas with high levels of geothermal activity. These geothermal vents have a tendency to create globular deposits of valuable ...

The long-term vision for deep sea mining is a swarm of C-Rays, communicating via hive mind, scouring the seafloor. They'll seek out surface deposits of precious materials — called polymetallic nodules — and put them into cages that could then be floated up to the surface.
