Smackover Lithium's LG Energy Solution Deal: A Look at Direct Lithium Extraction and Domestic Supply

On August 31, 2026, Smackover Lithium, the joint venture between Standard Lithium and Equinor, announced a 10-year lithium offtake agreement with LG Energy Solution. This deal commits to a multi-year supply of U.S.-produced lithium carbonate from their South West Arkansas Project. The agreement highlights the growing push to localize critical mineral supply chains, moving beyond traditional sources. It also underscores the increasing viability of direct lithium extraction (DLE) technologies for commercial-scale production. The LG Energy Solution deal is not just another offtake. It represents a concrete commitment to a specific extraction method in a specific region. For battery manufacturers, securing domestic, long-term supply from a known source mitigates geopolitical risk and supply chain volatility. For lithium producers, a major offtake agreement provides the revenue certainty needed to finance and de-risk large-scale projects. This particular agreement focuses on lithium from brine, extracted using DLE, which alters the cost structure and environmental footprint compared to hard rock mining or conventional evaporation ponds.

The Mechanism of Direct Lithium Extraction from Brine

Direct Lithium Extraction, or DLE, is a set of technologies designed to selectively extract lithium ions from brine without the need for large evaporation ponds. This is a critical distinction from traditional brine operations, like those in the Atacama Desert, which rely on vast surface areas and months of solar evaporation. DLE aims for a smaller environmental footprint and faster processing times. The core challenge is isolating lithium from other dissolved salts, primarily magnesium, calcium, and potassium, which are often present in much higher concentrations. Various DLE methods exist. Adsorption-based DLE uses materials that selectively bind lithium ions. Ion-exchange DLE employs resins that swap lithium for another ion. Solvent extraction DLE uses organic solvents to separate lithium. Each method has specific chemical requirements and operational complexities. The key to successful DLE is high selectivity for lithium, high recovery rates, and efficient regeneration of the extraction material. After extraction, the concentrated lithium solution is then processed into battery-grade lithium carbonate or lithium hydroxide. The brine, now depleted of lithium, is reinjected into the subsurface, minimizing water consumption and surface disturbance. This reinjection step is crucial for environmental permitting and public acceptance, particularly in regions with water scarcity concerns.

Companies Working in this Part of the Sector

Several companies are advancing projects focused on lithium from brine, often employing or exploring DLE technologies. Standard Lithium Ltd. (SLI), with its South West Arkansas Project, is a prominent player. The company's joint venture with Equinor, Smackover Lithium, is developing this project in the Smackover Formation, a geological brine reservoir. Their focus is on commercializing DLE technology to produce battery-grade lithium carbonate. The recent LG Energy Solution offtake deal validates their progress. ioneer Ltd (IONR) is another company developing a significant brine project, the Rhyolite Ridge Lithium-Boron Project in Nevada. This project is unique because it targets both lithium and boron from a single ore body. Boron is a critical component in certain advanced materials and has applications beyond batteries. IONR aims to produce lithium carbonate and boric acid. Their approach involves open-pit mining followed by acid leaching, rather than deep brine extraction, but it still represents a complex chemical processing challenge. American Battery Technology Company (ABAT) is working on a different angle of the battery supply chain, focusing on lithium-ion battery recycling and primary mineral extraction. While known for recycling, ABAT is also developing a lithium hydroxide production facility in Nevada. Their strategy involves both recovering critical minerals from spent batteries and extracting lithium from Nevada claystone resources, which presents its own set of processing hurdles distinct from brine. ABAT recently hosted Department of Energy leadership to showcase its commercial technologies, indicating government interest in their approach. Atlas Lithium Corporation (ATLX) is primarily focused on hard rock lithium deposits in Brazil. While not directly involved in DLE from brine, their operations highlight the diverse geological sources for lithium. Their Minas Gerais project aims to produce spodumene concentrate, a common feedstock for lithium chemical production. This contrasts with the DLE-focused companies, showing the varied pathways to market for lithium. NioCorp Developments Ltd. (NB) is developing a niobium, scandium, and titanium project in Elk Creek, Nebraska. While not a lithium pure-play, NioCorp's project targets other critical minerals essential for high-performance alloys and advanced technologies. Their focus is on hard rock mining and processing to produce these specialized metals. Critical Metals Corp. (CRML) is working to acquire European Lithium, which holds the Wolfsberg Lithium Project in Austria. This project is a hard rock spodumene deposit, again distinct from brine-based DLE. CRML's proposed acquisition, with a September court date for the merger, aims to establish a European source of lithium, emphasizing regional supply chain security. USA Rare Earth, Inc. (USAR) is developing the Round Top heavy rare earth and critical minerals project in Texas. This project targets a wide array of critical minerals, including rare earth elements, lithium, and other high-tech metals, from a rhyolite deposit. Their approach involves acid leaching to recover these elements, presenting a different chemical processing challenge compared to brine DLE.

American Lithium Minerals, Inc.

American Lithium Minerals, Inc. (AMLM) operates as an exploration stage company, currently pre-revenue, trading over the counter. The company's stated focus is on lithium and boron properties located in Nevada. AMLM's current project is the Sarcobatus Lithium property, which consists of 1,780 acres of mining claims situated in Central Nevada. The company was incorporated in Nevada in March 2005. Its activities since 2009 have centered on lithium exploration in this region. The public record does not yet establish a measured or indicated resource estimate for the Sarcobatus project. AMLM's most recent substantive filing, a Regulation A offering circular qualified on February 4, 2026, outlines plans to expand exploration and acquisition for mineral properties worldwide. The company is also exploring the use of Real World Asset Tokens to provide capital for mining operations. This strategy aims to merge public market credibility with blockchain technology for asset liquidity. The offering covers up to 80,000,000 units, each including one share of common stock and a warrant to purchase 1.5 shares, with up to 120,000,000 additional shares issuable upon full warrant exercise. The warrants are exercisable at $0.05 per share until December 31, 2028. Beyond the Sarcobatus Lithium property, AMLM has previously acquired and divested cobalt, nickel, and graphite prospects in Central Nevada, and rare earth elements projects in Kingman, Arizona and Southeast Illinois. The company does not currently own any real property such as land or buildings.

What to watch

The Standard Lithium and Equinor joint venture will continue to provide updates on the South West Arkansas Project's development. Watch for further details on the project's financing, construction timelines, and progress towards commercial production following the LG Energy Solution offtake. For Critical Metals Corp. (CRML), the September court date for the proposed acquisition of European Lithium is a key event. A successful merger would advance the Wolfsberg Lithium Project towards development. American Battery Technology Company (ABAT) will likely release more information on its lithium hydroxide production facility and the progress of its claystone lithium extraction efforts in Nevada. Updates on the reinstatement of their $57 million DOE grant are also relevant. ioneer Ltd (IONR) shareholders should monitor progress on the Rhyolite Ridge project, particularly regarding permitting and any further offtake agreements for either lithium or boron. For American Lithium Minerals, Inc. (AMLM), watch for any announcements regarding exploration results, resource estimates, or the advancement of their Sarcobatus Lithium property in Central Nevada.
