It is becoming increasingly harder to extract minerals on land in an environmentally and socially acceptable manner. The rate of new major mineral discoveries is slowing and the environmental and social costs on land have risen due to declining mineral grades and more complex ores with higher impurities.
In contrast, and due to their location and specific geological and mineralogical characteristics, obtaining society’s essential metals from seafloor polymetallic nodules can have significant environmental advantages, including:
Metals play an essential role in society: used in equipment to harvest and transport our food; in the construction of our homes, schools and buildings; in the pipes that supply our water; in wires that power our lighting and telecommunications infrastructure; and in medical devices supporting our physical wellbeing. Lack of access to these metals at affordable prices is a growing threat to long-term social development, particularly in third world countries. DeepGreen is looking to open up a new sustainable supply of these essential raw materials.
