Key Development:

United States: Recent Industry Developments

✅ In March 2026, The Metals Company submitted a consolidated application under U.S. seabed mining regulations to advance polymetallic nodule extraction projects in the Pacific Ocean. The application supports future commercial-scale deep-sea mining for battery metals such as nickel, cobalt, and manganese. It strengthens U.S. efforts to secure critical mineral supply for clean energy and advanced technologies.

✅ In February 2026, the U.S. government accelerated policy discussions on domestic deep-sea mining to reduce dependence on foreign critical minerals. The initiative focuses on enabling mining activities under national regulations instead of waiting for international approval. It reflects growing demand for strategic metals used in electric vehicles, defense, and renewable energy systems.

✅ In January 2026, U.S.-linked deep-sea mining projects expanded technology testing for collecting polymetallic nodules from depths exceeding 4,000 meters using offshore production vessels. The trials demonstrated the feasibility of lifting mineral-rich nodules to surface processing ships. The development supports commercialization of seabed mining for next-generation battery materials.

Japan: Recent Industry Developments

✅ In March 2026, Japan successfully retrieved rare-earth-rich sediment from the seabed near Minamitorishima Island using deep-sea drilling technology. The project demonstrates the feasibility of extracting critical minerals from depths of nearly 6,000 meters. It supports Japan's strategy to strengthen domestic supply chains for high-tech and electric vehicle materials.

✅ In February 2026, Japan continued pilot testing of deep-sea rare-earth extraction systems designed to recover mineral-rich mud from its exclusive economic zone. The government-backed project aims to enable commercial-scale production of rare earth elements in the coming years. It reduces reliance on imported resources for electronics and battery manufacturing.

✅ In January 2026, Japan launched advanced offshore testing of deep-sea mining technology capable of operating at depths greater than 6,000 meters. The program focuses on extracting rare earth elements used in batteries, semiconductors, and renewable energy equipment. The initiative strengthens Japan's leadership in marine mineral resource development.
