The Big Picture: A Game of Supply Chains and Power Plays
This week, the critical minerals sector was nothing short of a geopolitical chessboard—including a fiasco of a meeting between Zelenskyy and Trump—with moves that could shape the future of energy, technology, and global supply chains.
China is ramping up lithium production, American Rare Earths is flexing its domestic muscle, and Trump is making headlines (again) with a strategic pivot toward rare earths. Investors, policymakers, and industry leaders: buckle up.

1. The Next Lithium Revolution? Tin Foam Electrodes Shake Things Up
If you've ever worried about your smartphone battery swelling up like a balloon, imagine that problem at the scale of an electric vehicle. Enter tin foam electrodes: a breakthrough from German researchers that could solve one of the biggest bottlenecks in lithium-ion battery performance. Unlike traditional tin foils, which expand and contract dramatically during charge cycles (and eventually break), the porous structure of tin foam absorbs this stress, increasing battery longevity and efficiency.
2. American Lithium’s Big Bet on Nevada
American Lithium has delivered a 47% boost in measured lithium carbonate resources at its Tonopah Lithium Claims (TLC) in Nevada, now standing at 6.17 million tonnes of LCE. The company is eyeing an annual production capacity of 38,000 tonnes of battery-grade lithium over 40 years. Despite this, shares dipped 3.4%—a classic case of "buy the rumor, sell the news."
3. American Rare Earths: A Billion-Dollar Opportunity?
American Rare Earths (ASX: ARR) is making waves with an updated scoping study on its Halleck Creek project, revealing an NPV of up to $1.17 billion and a strong internal rate of return (IRR) of 28.4%. Given that rare earths are central to high-tech industries—think EVs, defense, and renewable energy—ARR’s progress is significant.
4. China’s Lithium Surge: Oversupply or Strategic Masterstroke?
China reported a staggering 45% increase in lithium carbonate production, reaching 670,000 metric tons in 2024. This move, despite falling global lithium prices, suggests China is playing the long game—securing dominance over lithium refining and processing, even if it means short-term price pain.
5. Trump’s Ukraine Play: Rare Earths for Influence?
In a move that’s as bold as it is controversial, Donald Trump is reportedly pushing Ukraine to develop its mineral resources in exchange for U.S. support. Given China’s rare earth dominance, securing alternative sources—like Ukraine—could be a game-changer for the U.S.
6. Argentina’s Lithium Land Grab
American Salars Lithium has increased its land position by a jaw-dropping 1,635% in Argentina’s Lithium Triangle, now holding 13,880 hectares. Given the region’s lithium abundance, this expansion could pay off massively.
Looking Ahead: What to Watch Next Week
Halleck Creek Scoping Study: Will the U.S. government take action to support domestic rare earths?
China’s Lithium Strategy: Will Western governments impose tariffs or other countermeasures?
Ukraine’s Critical Minerals Deal: Will Trump’s push materialize into a formal agreement?
Argentina’s Lithium Market: Expect more land grabs and project announcements in the region.
