Japan Demonstrates Deep-Sea Mud Mining for Rare Earths, Signals Tech and Policy Hurdles

Japan conducted a deep-sea mining test near Minamitorishima, successfully pumping mud from about 6,000 meters depth rich in rare earth elements, a government-led milestone toward diversifying supply away from China. The test focuses on proving the pumping capability rather than immediate commercial volumes, with plans to scale to hundreds of tons per day in the future, while environmental impacts and international regulatory rules for seabed mining remain contested.

Trump eyes Greenland's mineral riches in strategic framework

The piece explains that Trump’s Greenland framework is said to include US rights to minerals, as Greenland is believed to host oil and gas and a large share of Europe-listed critical minerals (about 25 of 34), including graphite, niobium and titanium. The move fits a broader US aim to curb China’s rare-earth dominance and secure strategic resources, but mining there faces high costs, harsh weather, limited infrastructure and just two productive mines despite many exploration permits. Melting ice could ease fieldwork and open opportunities, but actual development remains uncertain.

Greenland's Under-Ice Riches Could Shift the Global Resource Map

Greenland sits on vast, largely under‑ice reserves of critical resources—rare earth elements, other minerals, and substantial hydrocarbons—tied to its complex geologic history. While onshore and sub-ice deposits could reshape the global supply of REEs and energy minerals, exploration is expensive, environmentally sensitive, and tightly regulated, with climate-driven ice melt potentially both opening and complicating access.

Greenland's Resources and Strategic Significance in Focus

Greenland, rich in natural resources including critical raw materials like lithium and rare earth elements, has significant mineral and hydrocarbon potential due to its complex geological history. However, climate change-induced ice melt exposes these resources but complicates sustainable extraction, raising environmental and geopolitical concerns amid increasing interest from countries like the US and Denmark.

Nvidia Resumes China Shipments Amid Ongoing Trade and Regulatory Challenges

Nvidia plans to restart sales of its H20 AI chip in China, a move linked to ongoing trade discussions involving rare earth elements, which are crucial for technology and heavily mined in China. This decision has sparked debate over export controls and national security, with Nvidia asserting it is only offering China a less advanced chip. The U.S. continues to refine its export policies for AI chips amid broader trade tensions with China.

China-U.S. Trade Deal Boosts Markets and Rare Earth Exports

China and the US have confirmed a trade framework agreement, with the US agreeing to lift restrictions and China to review export applications, signaling a potential easing of trade tensions. The deal follows earlier talks and aims to ensure supply of critical rare earth elements, while China prepares for diplomatic visits to Europe. Shares in global markets rose on signs of improved US-China relations.

US Coal Ash Revealed as Rich Source of Rare Earth Elements

A study by The University of Texas at Austin reveals that coal ash in the U.S. contains up to 11 million tons of rare earth elements, potentially boosting domestic supply without new mining. This discovery could reduce reliance on imports, mainly from China, and transform coal ash from waste to a valuable resource. The research highlights the potential for extracting these elements from coal ash, which is abundant and already processed, though challenges remain in developing the necessary extraction infrastructure.

"Eggshell Waste: A New Source for Rare Earth Element Recovery in Green Energy"

Researchers from Trinity College Dublin and iCRAG have discovered that eggshell waste can be used to recover rare earth elements (REEs) from water, offering an eco-friendly and low-cost method for extracting these critical materials needed for green energy technologies. The study, published in ACS Omega, highlights how calcium carbonate in eggshells can absorb and separate REEs, potentially transforming waste into a valuable resource and supporting sustainable practices.
