US Rare Earths is preparing to acquire the remaining stake in its Round Top rare earths deposit in Texas in a transaction valued at approximately $73 million.
The Stillwater, Oklahoma-based company plans to purchase all outstanding shares of Texas Mineral Resources Corp. The deal, valued at around 3.8 million shares of US Rare Earths stock, would consolidate full ownership of the project.
Round Top is considered one of the largest heavy rare earth deposits in the United States, containing elements critical for permanent magnets used in electric vehicles, robotics, semiconductors, and defense systems. The asset is central to US Rare Earths' strategy of building a vertically integrated, domestic supply chain spanning mining, processing, and magnet manufacturing. The company is also developing a magnet factory in Oklahoma to support this "mine-to-magnets" model.
The move comes amid increased U.S. government policy support for critical minerals. Earlier this year, the U.S. government proposed a $1.6 billion debt and equity financing package, which could potentially come with a 10% federal equity stake in US Rare Earths. This is part of broader efforts to reduce dependence on China's dominance in rare earth processing.
US Rare Earths shares were trading at $19.14 in pre-market activity on March 5, 2026, up about 1.22% from the previous close.
