While economists and geologists worry the world's supply of rare earth metals will soon be outpaced by demand, a team of German geochemists has found a way to easily extract them from the vast deposits lying under the sea.
[ More ]The world's first deep sea mining robot sits idle on a British factory floor, waiting to claw up high grade copper and gold from the seabed off Papua New Guinea (PNG) - when a wrangle over terms is solved.
[ More ]The Cook Islands expects a mining boom if government plans are approved by the international body that governs deep-sea mining. But one NGO has warned about the potential consequences.
[ More ]The prospect of a race to the bottom of the ocean – a 21st-century high seas version of the Klondike gold rush – has alarmed scientists. The oceans, which make up 45% of the world’s surface, are already degraded by overfishing, industrial waste, plastic debris and climate change, which is altering their chemistry. Now comes a new extractive industry – and scientists say governments are not prepared.

Deep-sea mining is floundering. The leading company in the race to mine the ocean floor has fallen out with its host government, while other projects have been delayed until the environmental effects are better understood.
[ More ]Scientists have made an impassioned plea for humanity to pause and think before making a headlong rush to exploit the deep sea. The researchers said the oceans' lowest reaches had untold riches that could benefit mankind enormously, but not if the harvesting were done destructively.
[ More ]The last great unexplored wilderness on Earth is about to experience industrial-scale mining that could change the face of the pristine seabed of the deep ocean for generations to come, scientists have warned.

Brazil's national geological service (CPRM) has submitted to Jamaica-based International Seabed Authority (ISA) a working plan for the exploration of a cobalt-rich ferromanganese crust in international waters, the latter said in a release.
[ More ]New interest in the exploitation of seabed minerals has led to the revival of old concerns for the preservation of our oceans, argues Michael W. Lodge, Deputy to the Secretary-General and Legal Counsel of the International Seabed Authority.
