  • Deep sea mining is less wasteful than landbased mining

    Deep sea mining is less wasteful than landbased mining

    Many of these advantages are due to the high grades of deposits, more than 10 times higher than those found on land. Most mining operations on land produce a huge amount of waste while deep sea mining proves to be much less wasteful. Secondly, even with these advantages, Nautilus is dedicated to setting a high environmental responsibility standard.
