Deep Sea mining, like asteroid mining, is a relatively unconventional method of extracting Rare Earth elements (REEs). Unlike asteroid mining, however, deep sea mining has already been undertaken through projects such as deep sea diamond mining. Actual mining for REEs has not been attempted because of environmental issues and cost.

More than a million square miles of the deep sea’s floor have remained untouched for millennia. But that is changing rapidly. Industry and alternative energy solutions drive the rising demands for ocean minerals. Seabed mining also offers an attractive solution as deforestation criticisms rise and terrestrial supplies decline.

Marine minerals > Natural gas and oil have been extracted from the seas for deca­­des, but the ores and mineral deposits on the sea floor have attracted little interest. Yet as resource prices rise, so too does the appeal of ocean mining. The excavation of massive sulphides and manganese nodules is expected to begin within the next few years.

• Deepsea 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.
