Reporting of seafloor Mineral Resources AMC

Reporting of seafloor Mineral Resources. Interest in the exploration and mining of seafloor mineral deposits continues to grow, spurred on by a range of factors including decreasing deposit grades on land and the development of new subsea mining technology. Leading the race to seabed production is Nautilus Minerals, which announced in September

Deep-sea mining: plundering the seafloor’s minerals

2019-2-18  These metal-containing deposits are located around mid-ocean ridges where the sea floor is, or was, volcanically active. Mineral-rich superhot water from underlying magma meets cold deep seawater and forms a crust on the seafloor at a depth that is often richer in minerals, particularly copper, than can be found in land deposits.

Seafloor Mining Woods Hole Oceanographic

2021-5-21  Hot, buoyant, mineral-laden fluids rise from deep within ocean crust and mix with cold seawater. That triggers the precipitation of minerals that form deposits near and on the seafloor. Precipitating minerals also form seafloor "chimneys," and mineral particles in the fluids venting at the seafloor make the fluids look like
