Japan to Launch World's First Sustained Deep-Sea Rare Earth Mud Trial Mining off Minamitorishima in 2026

Published: Dec 25, 2025 11:32
[SMM Flash: Japan Initiates Trial Mining of Rare Earth-Rich Deep-Sea Mud off Minamitorishima] Japan is set to conduct a one-month trial mining operation for rare earth elements in the deep-sea waters surrounding the remote Minamitorishima. The trial will attempt to continuously extract rare earth-rich seabed mud from depths of approximately 6,000 meters below the sea surface, marking the world's first sustained mining test of rare earth mud ore at such depths. The trial is being led by the Japan Agency for Marine-Earth Science and Technology, with the operation area located approximately 1,900 kilometers southeast of Tokyo, Japan. The operational window is scheduled from January 11 to February 14, 2026. Currently, Japan has not set a specific mass production target for this deep-sea rare earth project but has outlined a phased development plan: if the trial is successful, the Japan Agency for Marine-Earth Science and Technology will launch a scaled demonstration mining operation in February 2027, with the mining capacity expected to maintain the trial's daily rate of 350 metric tons.

For NEVs, the core impact of Project Vault does not lie in how much it drives up mineral prices in the short term, but in the following: improved certainty of subsidy compliance, reduced supply disruption risks at key nodes, and the formation of a more stable structural price spread between the compliant and non-compliant supply chains.

Chile Unveils National Critical Minerals Strategy Amid Global Demand Surge
Chile has released its National Critical Minerals Strategy, clearly positioning itself as a stable supplier of minerals. Currently, driven by artificial intelligence, the development of new technologies, and the energy transition, global demand for these critical minerals continues to grow. The announcement of this strategy holds particular significance in the weeks before President Boric leaves office, highlighting Chile’s intention to transition from over-reliance on the copper industry toward adapting to a decarbonized economy and achieving resource diversification. Chile has identified 14 critical minerals, specifically covering copper, lithium, molybdenum, rhenium, cobalt, rare earths, antimony, selenium, tellurium, gold, silver, iron ore, boron, and iodine. Based on Chile’s current position in the global market, these 14 minerals are categorized into three groups: The first category includes copper, lithium, molybdenum, and rhenium. Their respective shares in global supply are 23%, 20.4%, 14.6%, and 46.8%, and other major economies have also designated these minerals as critical. The second category consists of minerals that are currently not produced or only produced in small quantities, including cobalt, rare earths, antimony, selenium, and tellurium. The third category comprises minerals already produced domestically in Chile with the potential to expand their role in the global value chain, such as gold, silver, iron ore, boron, and iodine.
