Japanese scientists discovered 230 million tons of rare earth metals at the bottom of the sea

Japanese researchers have discovered more than 230 million tons of rare earth metals, valued at 24.8 billion euros.

Currently about 95% of the world's rare earth metals come from ChinaTherefore, the discovery of such significant sources outside this region represents an important boost to both the economy and production of the host countries.

The reason these materials are so valuable is because of their use for the production of lithium-ion batteries — in particular in technologies such as smartphones, hybrid cars and aircraft. This is why the discovery of rare minerals around the ports of the Minemi-Tori-shima islands by Japanese researchers is so significant, not only giving the country a huge economic boost but also strengthening its production capacity.

Researchers “studied” more than 100 sections of the seabed at a depth of up to 5,200 meters and found a real treasure. According to the Nippon Foundation, the study area is believed to contain a dense field of 230 million tons of “easily extractable manganese deposits” that extends over an area of ​​about 10,000 square kilometers. This includes 610,000 tons of cobalt and 740,000 tons of nickel — enough to meet Japan's needs for 75 and 11 years, respectively.

Currently, one metric ton of cobalt sells for $24,080, while the same mass of nickel costs $15,288. Thus, if Japan were to sell the entire estimated find, it would receive just over 24.8 billion euros, which would provide a significant boost to the economy. However, since Japan is currently imports almost all rare earth materials, It's understandable that she would want to keep most of this find for herself.

Demand for such materials is expected to grow by 400-600% as battery-powered technologies become a mainstream requirement, replacing industries that previously relied on natural gas and oil.

The find could be a major boost for companies based in Japan. According to Yasuhiro Kato, a professor specializing in resource geology at the University of Tokyo, Japan plans to extract about three million tons of materials annually, while the university itself will provide detailed analysis of the extracted resources. This limited annual extraction is also important because it minimizes the impact on the marine environment, as “hunting” for coal in other ocean areas has proven to be a devastating risk.
