BlackRock’s 1.8M Share Grab Ignites UAMY’s Antimony Surge
BlackRock’s Stake Signals Bright Days for UAMY’s Critical Minerals Ambitions

When BlackRock, the titan of institutional investing, makes a move, the market listens. Their latest play? A hefty increase in their stake in United States Antimony Corporation (NYSE: UAMY), reportedly adding 1,828,051 shares to reach a 5.1% ownership, per a recent 13F filing. Wall Street’s whispering, the stock’s ticking up, and investors are wondering: is UAMY the next critical minerals darling? Spoiler alert: the signs are hard to ignore.
United States Antimony Corporation isn’t your average mining stock. As the only U.S. producer of antimony—a critical mineral powering everything from defense tech to flame retardants—UAMY holds a unique spot in a world grappling with supply chain jitters. With China tightening its grip on antimony exports, UAMY’s strategic importance is skyrocketing. And they’re not sitting still. The company recently announced a bold expansion of its Thompson Falls, Montana smelter, aiming to boost production sixfold to over 300 tons per month by year-end, all for under $15 million. Talk about punching above their weight!
BlackRock’s Vote of Confidence
BlackRock, managing a cool $4.76 trillion in assets, doesn’t make moves lightly. Their reported increase of 1,828,051 shares in UAMY, bringing their stake to an estimated 5.1% (roughly 5.68 million shares based on current data), is a neon sign flashing “potential.” While the math gets a bit fuzzy—1.828 million shares alone suggests 1.64% of UAMY’s 111.44 million outstanding shares—the 5.1% figure likely reflects aggregated holdings across BlackRock’s sprawling empire. Regardless, this isn’t pocket change; it’s a calculated bet on UAMY’s growth as a domestic antimony leader.
Why the enthusiasm? UAMY’s smelter expansion, coupled with talks with the Department of Defense, positions it as a linchpin in securing U.S. critical mineral supplies. With antimony demand surging for batteries, solar tech, and military applications, BlackRock’s move screams confidence in UAMY’s ability to deliver.
