Deep-sea mining tests resume after robot rescued from Pacific Ocean floor
The Peninsula
Belgium's Global Sea Mineral Resources has resumed tests that could lead to the mining of battery minerals from the Pacific Ocean floor after it managed to recover a robot stranded at a depth of thousands of metres.
Global Sea Mineral Resources (GSR) has been testing Patania II, a 25-tonne mining robot prototype, 4 km (13,000 ft) below the surface in its concession in the Clarion Clipperton Zone since April 20. The machine, named after the world's fastest caterpillar, became detached on Sunday from the 5km cable connecting it to GSR's ship, but a recovery operation reconnected it and brought it back to surface late on Thursday.More Related News
