China Rare Earth's Shenghe Resources bid ripples through US critical minerals

On September 18, 2026, news broke that Shenghe Resources, a significant Chinese shareholder in MP Materials, was in acquisition talks with China Rare Earth. This development marks a clear escalation in China's strategic consolidation of its critical minerals sector. For investors holding positions in US-based rare earth and lithium plays, this isn't just a headline; it's a direct signal about the tightening grip of state-backed entities on a crucial global supply chain. The implications for MP Materials (MP), which operates the Mountain Pass rare earth mine in California, are immediate. Shenghe Resources holds a substantial stake in MP Materials and has been a key offtake partner. A shift from a publicly traded Chinese company to a direct state-backed entity as a major shareholder introduces new layers of complexity, particularly given the ongoing US-China tensions over critical mineral independence. This move forces a re-evaluation of supply chain security and the true cost of domestic processing.

The structure of rare earth separation

Rare earth elements, or REEs, are not found in isolation. They occur together in mineral deposits, often as complex oxides. The challenge lies in separating these 17 chemically similar elements into individual, high-purity oxides. This separation is technically demanding and capital-intensive. It typically involves a multi-stage solvent extraction process. Crushed ore first undergoes beneficiation to create a concentrate. This concentrate then enters a hydrometallurgical circuit, where acids leach the REEs into a solution. The crucial step follows: a series of hundreds of mixer-settler units, each designed to selectively extract one rare earth element from the solution using organic solvents. The process demands precise chemical control, significant energy, and a large footprint. The difficulty of achieving high purity for individual heavy rare earth oxides, like dysprosium and terbium, is particularly acute. China dominates this separation capacity, a bottleneck that has long constrained Western efforts to build independent supply chains. The purity of the separated oxides directly impacts their utility in high-performance magnets and other advanced technologies.

Companies navigating the critical minerals landscape

Several companies are working to establish or expand critical mineral supply chains outside of China's direct influence. These efforts span the full spectrum from mining to processing. MP Materials (MP), trading at $15.37, operates the Mountain Pass mine in California, currently the only integrated rare earth mining and processing facility in North America. While it mines and processes rare earth concentrate, it has historically sent much of that concentrate to China for final separation. The company is actively working to bring full separation capabilities online at Mountain Pass, aiming to produce finished rare earth oxides and eventually magnets. News on September 13 indicated MP Materials was nearing its neodymium-praseodymium (NdPr) target and eyeing GM magnet deliveries by year-end. USA Rare Earth, Inc. (USAR), priced at $15.37, is developing the Round Top heavy rare earth and critical minerals project in Texas. The company is focused on establishing a fully integrated rare earth supply chain in the US, from mine to magnet. News on September 18 highlighted USAR's AI-driven approach to rare-earth processing, suggesting a focus on technological innovation to overcome separation challenges. Critical Metals Corp. (CRML), trading at $6.73, is focused on European critical mineral projects. On September 16, Critical Metals projected up to $2.2 billion in annual revenue from its proposed Romanian refinery, following a study that demonstrated over 99% dissolution of eudialyte concentrate into 19 ultra-high-purity rare earth products from its Tanbreez project. This indicates a focus on advanced processing for heavy rare earths outside of traditional Chinese dominance. On September 15, news confirmed the court cleared its European Lithium deal for an October shareholder vote, advancing a merger. In the lithium sector, companies are developing projects across various geographies and resource types. Albemarle (ALB), a major global lithium producer, saw its stock sink on September 18 as analysts reset lithium assumptions, with Mizuho Securities adjusting its price target to $140 from $160. Despite this, the company continues its lithium expansion efforts, as reported on September 16. Albemarle's operations are globally diversified, including brine operations in Chile and hard-rock mines in Australia. Lithium Americas Corp. (LAC), trading at $14.12, is developing the Thacker Pass lithium clay project in Nevada. The company's stock dipped on September 18, though it remains a focus for retail investors watching European critical minerals demand. JPMorgan recently revamped its price target for LAC, as reported on September 12. Standard Lithium Ltd. (SLI), priced at $2.12, is focused on lithium brine projects in Arkansas. On September 20, Equinor posted a positive PEA for its Texas Lithium Project, a development that may inform broader brine extraction strategies. Standard Lithium itself cleared two significant hurdles toward a final decision on September 11, indicating progress on its projects. ioneer Ltd (IONR), at $3.43, is developing the Rhyolite Ridge lithium-boron project in Nevada, a unique co-production asset. American Battery Technology Company (ABAT), trading at $2.18, focuses on battery recycling and primary lithium hydroxide production from Nevada claystone. On September 14, ABAT reported FY26 financial results, delivering 407% revenue growth and positive adjusted gross profit, indicating progress in its diversified approach. The company also turned a profit, as reported on September 16, but faces a new export threat. Atlas Lithium Corporation (ATLX), priced at $2.90, is developing hard-rock lithium projects in Brazil. NioCorp Developments Ltd. (NB), at $3.58, is advancing its Elk Creek critical minerals project in Nebraska, which aims to produce niobium, scandium, and titanium, with potential for rare earth production as a byproduct.

American Lithium Minerals, Inc.

American Lithium Minerals, Inc. (AMLM), trading over the counter at $0.0721, is an exploration stage company incorporated in Nevada in 2005. The company's stated focus is on lithium and boron properties in Nevada. Its primary asset is the Sarcobatus Lithium property, which comprises 1,780 acres of mining claims in Central Nevada. The company's activities since 2009 have centered on lithium exploration at Sarcobatus. AMLM has also acquired and divested cobalt, nickel, and graphite prospects in Central Nevada, and rare earth elements projects in Kingman, Arizona, and Southeast Illinois. The company is pre-revenue and does not own any real property such as land or buildings. American Lithium Minerals qualified a Regulation A offering on February 4, 2026, covering up to 80,000,000 units. Each unit includes one share of common stock and a warrant to purchase 1.5 shares of common stock, exercisable at $0.05 per share until December 31, 2028. The offering could result in up to 120,000,000 additional shares if all warrants are exercised. The company intends to expand its exploration and acquisition for mineral properties worldwide. It is also developing the use of Real World Asset Tokens to provide capital for mining. The public record does not yet establish proven or probable reserves for the Sarcobatus Lithium property. The company's long-term vision, as stated in its filings, is to create an interoperable ecosystem where assets can be securely acquired, transparently tokenized, and efficiently traded, merging public markets with blockchain agility.

What to watch

The proposed acquisition of Shenghe Resources by China Rare Earth will likely see further regulatory scrutiny and announcements. Watch for official statements from MP Materials regarding any changes to its shareholder structure or offtake agreements. Specific dates to watch include October for Critical Metals Corp.'s European Lithium merger shareholder vote. For Standard Lithium, continued progress on its Arkansas projects will involve further permitting decisions and engineering studies following its recent hurdles cleared. American Battery Technology Company's financial results show revenue growth, so continued operational scaling and any new export regulations will be key.
