Index / Mining & Minerals - Evaluations / Deep Sea Mining

Michael Lodge reports that the global demand for natural resources continues to grow. As land-based sources decline, corporate and governmental attention is increasingly turning to an area of the planet that has been beyond reach until now, the ocean floor. Hailed as a new resource frontier, the deep seabed is home to a variety of valuable minerals and metals, which lie hidden in underwater ridges, seamounts and sediment, up to depths of 5,000 metres.

At present, under the United Nations Convention on the Law of the Sea - UNCLOS, any country or deep-sea mining company that wishes to... More →

Ali Somarin reported last year that a recent post discussed mining asteroids for natural resources. In this post Somarin opines about a subject in the opposite direction - to the deep sea. Like asteroid mining, the concept of deep sea mining is being driven by the dwindling availability of rare earth and other metals and the conclusion by geoscientists that such valuable resources can be found at the surace of and beneath the ocean floor. Unlike asteroid mining, however, sea mining is already happening. Diamond producer DeBeers, for example, mines diamonds from southern African waters, but at ... More →

A NGO study indicates deep-sea mining at Solwara 1 project could carry environmental and social costs 75-90 percent lower than terrestrial mines.

Oceanica environmental and social cost advantages may be even more impressive than Solwara 1.

Marks the first time an environmental group has affixed a dollar value to the environmental savings that prudent seabed mining can produce.

Data should help seabed mining industry develop in a manner that creates a net benefit for the environment. Study helps explain why NGO opposition to Oceanica has been almost non-existen... More →

WNN reports that the Rubin Central Design Bureau for Marine Engineering, based in St. Petersburg, Russia, is reviving plans from the 1980s to establish a system for the underwater exploration of mineral resources. The Russian Nuclear Community reports that federal agencies are considering the use of a nuclear reactor to power this proposed system.

The project, named Iceberg, will use a nuclear power unit that meets all the safety requirements of the International Atomic Energy Agency, according to the report. A new entity involving Rosatom, the Russian Defense Ministry, Gazprom, the... More →

Julian Smith opines that people have been mining minerals like iron and gold for millennia. And for much of our lives today, from the europium, terbium and yttrium that help illuminate the screen you are reading to the copper in the wires that power it, we increasingly depend on elements from the depths of the Earth. But finding new deposits gets harder every year and mines are steadily growing larger, more expensive and more environmentally destructive (exaggeration ...not true).

On land, that is. By some estimates the ocean floor has the largest resources of minerals such as coppe... More →

Gareth Tredway reports that Michael Johnston, the Nautilus CEO, recently told Mining Journal that the further down the development chain they get, the more interest there is in what we are doing. He says there is growing interest in the various milestones the company has been meeting and is expected to meet along the way.

One of those was the taking of delivery of the Seafloor Production Tools (SPTs) from the UK Soil Machine Dynamics in January. At PDAC in March, the company was able to show videos of the equipment at work rather than the 3D animations played previously.

Stefanie Heerwig reports in this well-referenced article that as we continue consuming metals and rare earths at the same rate as today, we could run out of existing resources within 20 years, according to an estimate of current resources and reserves worldwide.

Rare earths are the basis for state-of-the-art renewable technology like solar panels. And replacing oil, gas and coal with existing renewable energy technology would require the extraction of rare earths to increase by 700% over the next 25 years, according to the latest MIT research.

Given this pressing demand a... More →
