It is anticipated that the ocean geothermal system will be able to collect significant metals and minerals because seafloor hydrothermal fluids are particularly rich in metals and minerals, which vary depending on the location and circumstances of the resources (Tivey, 2007; Koski), and the supercritical temperature of the ocean geothermal brine renders it particularly effective at leaching such metals and minerals out of the rock.  The proposed ocean geothermal system will remove metals and minerals from the geothermal brine while it is in the heat exchanger.
