Deep sea mining is a relatively new mineral retrieval process that takes place on the ocean floor.Ocean mining sites are usually around large areas of polymetallic nodules or active and extinct hydrothermal vents at about 1,400-3,700 m below the oceans surface.The vents create sulfide deposits, which contain valuable metals such as silver, gold, copper, manganese, cobalt, and zinc.

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.
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.

Gold mining in Penhalonga represents all methods of gold extraction from deep underground mining, to small-scale mining with mines only a few metres deep, through large-scale alluvial mining and the most infamous gold panning. The area therefore is affected by the environmental impacts of each of these mining methods.
