Tokyo, Japan — A massive underwater treasure trove of minerals worth over $26 billion has been discovered near Minami-Tori-shima Island, including significant deposits of cobalt and nickel. These valuable resources, crucial for various high-tech applications, were found attached to fossilized teeth of the prehistoric Megalodon shark.
Key findings
- Mineral Deposits: The seabed contains dense manganese nodules enriched with 610,000 metric tonnes of cobalt and 740,000 metric tonnes of nickel, alongside copper.
- Value: Current market prices estimate cobalt at $24,300/tonne and nickel at $15,497/tonne, translating to a combined value of $26.3 billion.
- Origins: These minerals formed over millions of years, transported by fish bones that settled on the seabed, where they crystallized around Megalodon teeth.
Survey details
The discovery was made during a survey by the Nippon Foundation and the University of Tokyo, which explored depths of 5,700 meters. The research highlights Japan’s potential to leverage this find for its economy and technological advancements, especially as demand for such minerals grows due to the rise in electric vehicle (EV) production and renewable energy technologies.
Applications of cobalt and nickel
- Electric Vehicle Batteries: A key component in lithium-ion batteries.
- Jet Engines and Gas Turbines: Critical for high-temperature performance.
- Chemical Processing: Used in catalysts and alloys.
Mining and environmental concerns
Japan plans to begin extraction in 2025, targeting three million metric tons annually. The University of Tokyo has emphasized a commitment to minimizing environmental impact during mining. According to Yasuhiro Kato, a professor at the university, sustainable practices will be essential to protect marine ecosystems while maximizing resource recovery.
A press release stated:
“Our research outcomes will help boost Japan’s growth by establishing a domestic supply chain stretching from ‘resource-mining’ to ‘manufacturing.’”
Implications for Japan’s economy
This discovery comes at a critical time for Japan, as the country looks to reduce its reliance on imported resources. With enough minerals to sustain production for the next decade, this find could significantly bolster Japan’s economic resilience and position in the global tech market.
The connection to prehistoric Megalodon teeth adds an intriguing layer to this discovery, highlighting how ancient life can influence modern-day resource availability.
