Cutting-edge underwater mining system can give flooded mines a new lease of life

Europe has an estimated EUR 100 billion worth of unexploited mineral resources lying at depths of 500-1,000 m. Following centuries of active mining, the continent's more accessible mineral deposits are mostly depleted. However, there are still deep-lying resources in abandoned flooded mines and in unmined underwater deposits that can't be exploited using conventional dry mining techniques.
