Deposit Has Capacity To Produce 2,500 Tons Per Day Of Rare Earth Minerals. There Is Sufficient Nickel To Supply Japan’s Consumption For 75 Years And Cobalt For About 11 Years.
Revolution In Mining: Imagine a hidden treasure beneath the deep waters of the Pacific Ocean, near the remote island of Minami Torishima, where over 200 million tons of Rare Earths await exploration. Recently discovered by researchers from the renowned University of Tokyo, these nodules are not only rich in rare minerals like cobalt, copper, and nickel, which are crucial for modern battery technologies, but they also represent a gigantic economic potential for Japan.
This discovery promises not only to revolutionize the mining and technology industries but also to open new horizons for an era of sustainable innovation on the ocean floor. Get ready to explore the secrets of this oceanic treasure and find out why Minami Torishima has become an epicenter of hope and opportunity for Japan’s industrial future.

Researchers From The University Of Tokyo Discover Huge Deposit Of Rare Metals Near A Remote Japanese Island
More than 200 million metric tons of manganese nodules rich in rare metals called Rare Earths have been found on the seafloor near Minami Torishima, a remote island of Tokyo, according to reports from the Nippon Foundation and the University of Tokyo on Friday.

A 42-year-old miner was trapped for 14 days at a depth of 300 meters in a flooded gold mine in Mexico — when divers found him with water up to his waist, he said: ‘I did not lose faith.’

The United States wants to extract minerals from the bottom of the Pacific at a depth of 4,000 meters — the problem is that 90% of the species living there are still unnamed, and in tests, life on the seabed decreased by 37%.

Usiminas closed a contract to supply 5,200 tons of special steel for the four most advanced frigates the Brazilian Navy has ever built — each ship carries 1,300 tons of plates that need to resist the sea and explosions.

Two African countries will inaugurate in 4 days an 825-meter bridge suspended 90 meters high over a reservoir — it is the largest of three bridges of a megaproject that will supply millions of people.
The nonprofit organization and the national university discovered a substantial amount of concentrations on the seabed of rare earth minerals, containing rare metals like cobalt and nickel in abundance, both essential for lithium-ion batteries. The research covered an area at depths of about 5,000 meters in the country’s exclusive economic zone, off the island in the Pacific.
The Team’s Plan Is To Start Extracting 2,500 Metric Tons Of The Mineral Resource Per Day In An Experimental Project By The End Of March 2026.
The research team, led by Yasuhiro Kato, a professor at the university, estimates that there are 234 million tons of these minerals called Rare Earths in a study area of 100 square kilometers, with enough nickel to supply Japan’s consumption for 75 years and cobalt for about 11 years.
It is believed that the volumes are commercially viable for rare earth minerals considering extraction and refining costs. The team’s plan is to start extracting 2,500 tons of the mineral resource per day in an experimental project by the end of March 2026.
The Discovery By The University Of Tokyo Represents An Extraordinary Mineral Deposit In Japan’s EEZ
The spherical nodules, which can reach several centimeters in diameter, grow when iron and manganese oxides dissolved in seawater precipitate around their nuclei, similar to stones and shark teeth. The nodules also contain copper.
The significant concentration of manganese was initially discovered during a survey in the same area in 2016, conducted by a team that included members from the university and other organizations.
Between late April and early June of this year, a detailed sampling survey was conducted to determine estimates of the deposits of rare earths such as copper, nickel, cobalt, and manganese.
The discovery of these ores by the University of Tokyo represents an extraordinary mineral deposit in Japan’s EEZ, a country with limited resources. It is crucial to extract these resources as soon as possible for industrial supply. rare earths
Minami Torishima: A Remote And Strategic Location Rich In Rare Earth Minerals
Minami Torishima, also known as Marcus Island, is a small and remote Japanese island located in the Pacific Ocean. Here are some key aspects about this island:
Location: Minami Torishima is situated about 1,848 kilometers southeast of Tokyo, in one of the country’s most remote areas. It is the easternmost island of Japan.
- Size: The island has an area of approximately 1.2 square kilometers, making it quite small. rare earths
- Topography: The island is predominantly flat, with an elevation no higher than 10 meters above sea level. It is surrounded by coral reefs and has a tropical maritime climate.
History
- Discovery: The island was discovered in the 19th century and had a history of international disputes until Japan reaffirmed its control over it.
- Military Use: During World War II, Minami Torishima was used by the Imperial Japanese Navy as a weather station and airbase.
- Current Administration: Currently, the island is administered by the Japan Coast Guard and houses a weather station of the Japan Meteorological Agency.
Strategic Importance
- Exclusive Economic Zone (EEZ): The island is crucial for Japan’s EEZ, significantly extending the rights to exploit marine resources in this region.
- Natural Resources: As mentioned in the article, the region around Minami Torishima is rich in manganese nodules containing rare metals such as nickel and cobalt, essential for modern technology.
Biodiversity And Conservation
- Ecology: Despite its small size, the island hosts a variety of marine life in its surrounding coral reefs. However, due to its military and strategic use, terrestrial biodiversity is limited. rare earths
- Environmental Protection: Resource exploration in the region must be balanced with marine environment conservation, a challenge that Japan needs to manage carefully.
Access And Housing
- Access: Access to Minami Torishima is restricted mainly to military and scientific personnel. There is no infrastructure for tourists due to its remote location and strategic use.
- Infrastructure: The island has basic facilities to support the weather station and Coast Guard personnel, but has no permanent residents.
Minami Torishima is a small geographical point but of great importance to Japan, both strategically and in terms of natural resources such as the recent discovery of rare earths. Its isolation and the wealth found in its waters make this island a unique and valuable place for the country.

Engraçado falar-se em mineração “sustentável” em grande profundidade marítima com essa naturalidade. Aqui, onde todos os vizinhos exploram petróleo na Foz do AM, a Petrobrás explorar é crime ambiental.
