Appalachian Lithium Reserves Could Strengthen US Domestic Supply Security

USGS

Appalachian lithium reserves could give the US a much larger domestic resource base than previously recognised, according to a new assessment from the US Geological Survey. The agency said the eastern US Appalachian region may contain enough undiscovered, economically recoverable lithium to replace 328 years of US imports at 2025 levels.

Appalachian lithium reserves are hosted in pegmatites, large-grained rocks similar to granite. The southern Appalachian region is estimated to contain 1.43mn t of lithium oxide, while the northern Appalachian region holds another 0.90mn t.

Appalachian lithium reserves matter because the US still depends heavily on imported lithium. The country has only one current lithium producer and relied on imports for more than half of its supply in 2025.

The assessment adds another possible domestic supply route alongside lithium brine projects in the Smackover formation. Together, these resources could reshape US lithium strategy if they can be converted into permitted, economic and commercially scalable projects.

Pegmatite Resources Add a Hard-Rock Lithium Option

The Appalachian assessment points to hard-rock lithium potential in the eastern US. Pegmatite-hosted lithium is different from brine-based production because it usually requires mining, concentration and chemical conversion.

This gives the US another possible supply pathway. Hard-rock projects can produce spodumene concentrate, which can then be converted into lithium chemicals for batteries, energy storage and industrial uses.

Albemarle is already planning a lithium concentrator facility at Kings Mountain, North Carolina. The project is designed to produce 420,000 t/yr of lithium concentrate from spodumene.

That project is important because it could help rebuild a US hard-rock lithium supply chain. Domestic spodumene production would reduce reliance on foreign raw material and support future US conversion capacity.

However, resource estimates alone do not guarantee supply. Appalachian lithium projects would still need exploration, permitting, mine development, processing investment, environmental approvals and downstream customer qualification.

The strategic significance is still clear. The US lithium conversation is expanding beyond Nevada brines and western projects into eastern hard-rock resources with long-term supply potential.

Smackover Brines and Appalachian Pegmatites Broaden US Lithium Strategy

The Appalachian estimate follows earlier USGS work on the Smackover formation in southwest Arkansas. In 2024, the agency assessed that Smackover brines contain 5mn-19mn t of lithium, although it did not define economically recoverable volumes.

Several companies, including Equinor, ExxonMobil, EnergyX and Standard Lithium, are developing lithium projects in the Smackover region. Some are targeting commercial output around 2027.

The Smackover and Appalachian resource bases are strategically different but complementary. Smackover projects depend on brine extraction and processing technologies, while Appalachian projects would likely depend on hard-rock mining and spodumene concentration.

This diversification matters for US supply security. A lithium strategy based on multiple geological sources is more resilient than one dependent on a single basin, technology or company.

The US will still need processing capacity. Mining lithium ore or extracting lithium from brine does not automatically create battery-grade lithium carbonate or hydroxide.

That midstream gap remains the critical issue. Domestic resources must be connected to refining, chemical conversion, permitting, infrastructure and offtake agreements before they can reduce import dependence.

For battery manufacturers, the Appalachian assessment offers a long-term signal. More domestic resource potential could support future supply chains for electric vehicles, grid storage and defence-related battery applications.

The Metalnomist Commentary

The Appalachian lithium assessment is a resource-security signal, not an immediate supply solution. The US has the geology, but the decisive bottleneck will be converting resources into permitted mines, concentrators and battery-grade lithium chemicals.

Chevron Joins the US Lithium Hunt

Chevron US lithium

Oil Majors Target Lithium in Smackover Formation

Chevron has officially entered the US lithium sector, joining ExxonMobil and Equinor in exploring lithium-rich brines in the Smackover formation. The oil giant acquired about 125,000 net acres in northeast Texas and southwest Arkansas, where high lithium content in briny groundwater has already attracted major interest.

The company plans to leverage its subsurface expertise to extract lithium from brine, aiming for lower costs and reduced environmental impact compared with hard rock mining or evaporation ponds. Chevron says this effort aligns with its broader strategy to support US energy leadership and build resilient domestic lithium supply chains.

Expanding Lithium Supply Amid Energy Transition

Chevron’s move mirrors a growing trend of oil companies pivoting toward critical minerals to secure positions in the energy transition. Smackover Lithium, a joint venture between Standard Lithium and Equinor, has already announced plans to produce 22,500 t/yr of lithium carbonate by 2028. Meanwhile, ExxonMobil signed a deal in November 2024 to supply up to 100,000 t of lithium carbonate to South Korea’s LG Chem, also sourced from the Smackover formation.

As demand for EV batteries accelerates, the region could become a cornerstone of the US lithium industry. Chevron’s participation underscores the convergence of oil and mining sectors, with traditional hydrocarbon firms now competing in battery materials.

Strategic Implications for US Lithium Supply

Chevron’s lithium strategy emphasizes domestic production to reduce reliance on imports and strengthen critical mineral supply chains. By applying oilfield brine extraction techniques, the company hopes to commercialize lithium with fewer environmental trade-offs.

Industry analysts believe oil companies could soon rival established lithium producers. As independent analyst Joe Lowry noted, “By early next decade, big oil and big mining will replace the likes of Albemarle at the top of the lithium world.”

The Metalnomist Commentary

Chevron’s entry into the lithium market highlights a strategic realignment of oil majors toward critical minerals. The Smackover formation is fast becoming a global lithium hotspot, and Chevron’s move strengthens US ambitions for secure, domestic supply. If successful, this strategy could reshape the balance of power in the lithium industry, positioning oil giants as major players in the battery supply chain.

Smackover Lithium Phase 1 Approval Clears Path for U.S. Brine-Based Lithium Expansion

Smackover Lithium

The Smackover Lithium Phase 1 approval marks a major milestone for U.S. lithium production, as Arkansas regulators greenlight the company’s brine extraction plans. The Smackover Lithium Phase 1 approval allows the joint venture to begin developing its Reynolds brine unit as part of a broader strategy to scale domestic battery-grade lithium output.

Phase 1 Targets 22,500 t/yr from Reynolds Brine Unit

The Arkansas Oil and Gas Commission (AGOC) approved the establishment of a lithium brine production unit at the South West Arkansas (SWA) project. The Reynolds unit spans 20,854 acres and is set to produce 22,500 tonnes per year of battery-grade lithium carbonate. Full-scale Phase 1 production is targeted for 2028.

Smackover Lithium is a joint venture between U.S.-based Standard Lithium and Norwegian energy firm Equinor. The project is based in Lafayette and Columbia Counties and will be developed in two equal phases, ultimately reaching 45,000 tonnes per year.

U.S. DOE Grant Faces Political Uncertainty

The company received a $225 million grant from the U.S. Department of Energy in January 2025. However, this funding was placed on hold due to a presidential executive order issued by Donald Trump just days later, freezing clean energy funding programs.

Despite the uncertainty surrounding federal financing, Equinor and Standard Lithium remain committed to moving the project forward. Allison Kennedy Thurmond, Equinor’s VP of U.S. Lithium, emphasized ongoing collaboration with regulators and community stakeholders to secure a competitive royalty framework.

Direct Lithium Extraction at the Center of U.S. Supply Strategy

The Smackover project utilizes direct lithium extraction (DLE) technology, which offers a lower environmental footprint compared to traditional mining. As the U.S. seeks to localize battery supply chains, DLE projects like Smackover are gaining strategic importance.

Smackover’s Phase 1 approval places it among the leading North American lithium ventures, helping diversify global supply away from China-dominated sources and aligning with broader clean energy security goals.

The Metalnomist Commentary

The Smackover Lithium Phase 1 approval highlights the regulatory momentum behind U.S. lithium projects despite political headwinds. As federal funding remains uncertain, private and state-level partnerships will play an increasingly critical role in scaling brine-based lithium production.

US Targets 1 Million Tons of Lithium Production by 2035, Says DoE

Department of Energy (DOE)

The US Department of Energy (DoE) projects that the country could produce 1 million metric tons (t) of battery-grade lithium by 2035. This output would be sufficient to meet domestic demand while allowing for exports to trading partners.

Scaling Up Domestic Lithium Production

The DoE's Loan Programs Office Director, Jigar Shah, emphasized the need to expand lithium extraction, processing, and recycling to support the growing lithium-ion battery industry. He noted that diverse lithium resources across multiple US regions could be unlocked using advanced technology and infrastructure investments.

The US plans to increase lithium supply through three key sources:

• Spodumene deposits in Charlotte, North Carolina, expected to produce 100,000-150,000 t/yr of lithium carbonate equivalent (LCE).
• Albemarle’s Kings Mountain mine is one of the most advanced spodumene projects, projected to yield 50,000 t/yr of LCE.

• Brine and clay resources in Nevada, California's Imperial Valley, and the Arkansas Smackover Formation, estimated to contribute 500,000-1 million t/yr of LCE.
• These resources have lower lithium concentrations than South American reserves, but direct lithium extraction (DLE) technology can help process them efficiently.
• Recycling of end-of-life EV batteries, which could reduce the need for new lithium extraction, supplying 50,000-100,000 t/yr of LCE by 2035.

Government Investment in Lithium Infrastructure

The Biden administration has significantly increased investments in US lithium production to accelerate the clean energy transition.

In September 2024, the DoE selected 25 projects across 14 states, committing over $3 billion to expand domestic lithium supply. Additionally, the Thacker Pass lithium project in Nevada, operated by Lithium Americas, received a $2.3 billion loan to build a 40,000 t/yr lithium carbonate facility.

In December 2024, the DoE also allocated $17 million to 14 critical mineral technology projects, reinforcing efforts to scale up lithium production.

Lithium’s Role in the US Energy Transition

According to the US Geological Survey, the US has 1.1 million tons of lithium reserves, compared to a global total of 28 million tons.

Shah highlighted that advancements in direct lithium extraction (DLE) could rapidly unlock large lithium resources, much like hydraulic fracturing transformed the oil and gas industry.

With global lithium demand rising, the US is positioning itself as a key player in the lithium supply chain, reducing dependence on foreign imports and strengthening the clean energy sector.

Pure Lithium Secures $300mn EXIM Support for US-Based Lithium Metal Battery Facility

Pure Lithium Corporation

Pure Lithium has received a $300 million Letter of Interest (LOI) from the Export-Import Bank of the United States (EXIM) to support its planned industrial-scale lithium metal battery plant. If approved, the Pure Lithium EXIM loan would fall under EXIM’s “Make More in America” initiative aimed at rebuilding domestic manufacturing capacity and securing supply chains in strategic sectors like energy storage.

The proposed facility will use Pure Lithium’s proprietary “Brine to Battery” process, which directly converts brine into lithium metal anodes—eliminating graphite, cobalt, nickel, and manganese. This vertically integrated method enables a fully US-based battery supply chain, from raw material extraction to cell production. CEO Emilie Bodoin emphasized the project's potential to reshape global lithium battery sourcing models.

Disruptive Battery Chemistry Supports Strategic US Objectives

The Pure Lithium EXIM loan could accelerate commercialization of lithium metal vanadium oxide batteries, which offer higher energy density without relying on traditional cathode materials. This technology positions Pure Lithium at the forefront of post-Li-ion battery innovation, directly supporting the U.S. push for clean tech self-reliance.

Pure Lithium’s partnerships reinforce its vertically integrated vision. It sources lithium concentrate from E3 Lithium in Alberta, Canada, and collaborates with Saint-Gobain Ceramics to engineer water-blocking lithium-selective membranes—a key component in its novel extraction process.

EXIM Financing to Boost US Battery Supply Chain Resilience

EXIM’s Make More in America strategy supports projects that improve domestic industrial competitiveness in sectors facing global strategic risk. The Pure Lithium EXIM loan would directly address U.S. concerns over dependence on foreign-dominated battery material supply chains, especially China.

If finalized, the funding will catalyze Pure Lithium’s ability to scale manufacturing within U.S. borders while lowering barriers for next-generation battery adoption. This aligns with U.S. energy security goals and rising demand for alternative battery chemistries in defense, mobility, and grid storage sectors.

The Metalnomist Commentary

The Pure Lithium EXIM loan represents a critical step in reshoring advanced battery manufacturing. As supply chain risks intensify and lithium metal demand grows, projects that fuse innovation with domestic sourcing will shape the next era of U.S. battery independence.

Stardust Lithium Chloride Feedstock Agreement Supports Oklahoma Refinery Plan

Stardust Power

Stardust lithium chloride feedstock agreement has strengthened the company’s plan to supply its Muskogee, Oklahoma refinery with domestic lithium brine material for battery-grade lithium carbonate production. The deal covers lithium chloride feedstock from a California brine project, with initial deliveries scheduled for the first half of 2028.

The agreement could provide up to 15,000 t/yr of lithium carbonate equivalent. Stardust Power has not yet disclosed the specific project name or location, saying those details will follow after a definitive agreement is signed.

Stardust lithium chloride feedstock agreement is strategically important because the company’s Muskogee refinery is planned for up to 50,000 t/yr of LCE capacity. Securing feedstock is one of the most important requirements for any lithium conversion project, especially as the US tries to build more domestic battery materials capacity.

California Brine Supply Adds Domestic Feedstock Option

The feedstock will come from a lithium brine project in California, making the agreement part of a wider US push to connect brine resources with domestic refining. California’s Salton Sea region has become one of the most closely watched lithium extraction zones in North America.

Companies active in the region include Berkshire Hathaway Energy Renewables, EnergySource and Controlled Thermal Resources. Based on expected integration and potential volume, Controlled Thermal Resources is considered the most likely supplier.

This matters because lithium chloride from brine projects can become an important input for downstream lithium carbonate production. If direct lithium extraction and brine processing projects scale successfully, they could reduce US dependence on imported lithium chemicals.

The timing remains important. Deliveries are not expected until 2028, which means Stardust still needs to manage project development, financing, permitting, customer qualification and feedstock conversion before commercial output can be secured.

Muskogee Refinery Builds a Broader Lithium Supply Network

Stardust’s Muskogee refinery is planned to produce battery-grade lithium carbonate, a key material for cathode production and lithium-ion batteries. The project is designed for up to 50,000 t/yr of LCE capacity, making feedstock diversification essential.

The California agreement adds to Stardust’s existing feedstock network. Other partners include Prairie Lithium in Canada and Mandrake Resources in Utah, giving the company multiple potential raw material streams.

The company also has a non-binding offtake agreement with Sumitomo for up to 25,000 t/yr of LCE over 10 years. That agreement gives Stardust a potential downstream sales channel, but commercial execution will depend on turning feedstock agreements into qualified battery-grade production.

For the US lithium supply chain, the project reflects a broader challenge. Domestic refinery announcements are increasing, but long-term success depends on reliable brine supply, conversion technology, customer qualification and competitive production costs.

The Metalnomist Commentary

Stardust’s agreement shows that lithium refining projects are only as strong as their feedstock base. The Muskogee refinery could become a meaningful US lithium carbonate platform, but its real test will be converting domestic brine supply into bankable, battery-grade output.

Lithium Americas Thacker Pass project reshaped by US equity move

Lithium Americas

The Lithium Americas Thacker Pass project has entered a new phase as the US government links financing to direct equity. The Department of Energy (DOE) will take a 5pc stake in Lithium Americas and another 5pc in its joint venture with General Motors. This move reshapes risk sharing on the Lithium Americas Thacker Pass project and signals stronger US commitment to domestic lithium supply. As a result, the Lithium Americas Thacker Pass project now sits at the intersection of industrial policy, EV demand and capital markets.

US equity stake deepens support for Lithium Americas Thacker Pass project

The DOE has restructured its $2.26bn loan by adding equity warrants in Lithium Americas and its GM joint venture. This makes the US government not only a lender but also a partial owner of the Lithium Americas Thacker Pass project. LAC will draw an initial $435mn before the end of 2025, which will fund early construction and infrastructure. The joint venture structure remains intact, with Lithium Americas holding 62pc and operatorship and GM holding 38pc. This equity-linked design aligns incentives across government, miner and automaker, while anchoring long-term US battery material security.

The Thacker Pass development targets 160,000 t/yr of lithium carbonate across five phases. Each phase is planned at 40,000 t/yr, providing staged capacity that can track market demand. This phased approach reduces execution risk and gives lenders more confidence in the project ramp-up. It also lets the partners adjust capex timing if pricing or EV demand changes. For the DOE, the structure supports a scalable North American supply chain that can feed US gigafactories and reduce reliance on foreign lithium.

GM will also amend its offtake agreement to allow additional buyers into the portfolio. Under the existing terms, GM can take up to 100pc of Phase 1 and 38pc of total production for 20 years. The updated agreement will free some Phase 1 volumes for third-party offtake contracts. That shift reflects slower US EV adoption than previously expected and uncertainty after the expiry of key tax credits at the end of September. It also allows Lithium Americas to diversify its customer base and reduce single-buyer exposure.

Lithium Americas Thacker Pass project balances market risk and supply security

The Lithium Americas Thacker Pass project is now a test case for how policy-backed critical mineral projects manage demand cycles. On one hand, government equity and cheap debt lower financing costs and signal strong policy support. On the other, the partners must adapt to a softer EV sales trajectory and evolving battery chemistries. Allowing third-party offtake from early phases helps ensure plant utilisation and broader market participation. It also widens the strategic impact of Thacker Pass beyond a single OEM.

At the same time, the project remains central to US ambitions for a resilient battery supply chain. Domestic lithium carbonate output can reduce exposure to price spikes, export controls and shipping disruptions. The phased build-out allows careful monitoring of market conditions while keeping long-term capacity targets intact. If EV adoption reaccelerates later in the decade, Thacker Pass will already have a built foundation for further expansion.

The Metalnomist Commentary

The DOE’s equity stake turns Thacker Pass into a flagship example of industrial policy meeting market reality. The Lithium Americas Thacker Pass project gains financial strength and strategic backing, but must now prove it can thrive in a slower, more competitive EV landscape. For battery and automaker supply chains, the real story is optionality: diversified offtake and phased growth give this project room to adjust without losing strategic relevance.

US Tariffs May Spur Argentina Lithium Salts Production

US Tariffs

Tariff Exemptions Favor Lithium Raw Materials, Not Finished Batteries

The US has exempted lithium carbonate and lithium hydroxide from its newly announced tariffs, creating a possible boon for Argentina's lithium sector. While raw lithium salts escape extra duties, finished battery imports face steep tariffs: 64.9% for China, 24% for Japan, and 25% for South Korea.

This disparity aligns with US efforts to localize battery manufacturing, a movement accelerated by the Inflation Reduction Act under President Biden. With at least 10 new battery factories coming online in the US this year, the demand for lithium raw materials is surging.

Argentina’s Brine Lithium May Fill the US Supply Gap

The US faces a bottleneck in domestic lithium production and processing. Currently, Albemarle’s Silver Peak mine is the only active operation, producing just 5,000t/yr of technical-grade lithium carbonate, which lacks the purity needed for EV batteries.

As a result, the US will increasingly depend on lithium imports, especially battery-grade salts. Argentina, with its low-cost brine operations, may become a preferred supplier if its projects can consistently meet battery-grade specifications.

Brine operations, while slower to ramp up than hard-rock mining, are cheaper to operate and typically more cost-competitive over time. Argentina also offers a low 3% royalty tax, compared to Chile's 40% ceiling, enhancing its competitiveness.

Global Lithium Supply Chains May Shift Toward South America

Countries like Australia and Brazil, which mine spodumene, rely heavily on China for conversion, placing them in a higher tariff category. These spodumene-dependent nations now face at least 20% US tariffs due to their reliance on Chinese refining infrastructure.

Meanwhile, Argentina’s direct-to-battery-grade production strategy may give it an edge.

“All of Argentina’s lithium projects go to battery grade,” said Daniel Gonzalez, Argentina’s vice-minister of energy and mining.

If Argentina proves its capability at scale, the country could secure a dominant role in North America's clean energy transition, especially as the US reorients trade relationships in critical minerals.

The Metalnomist Commentary

With tariffs redrawing global battery supply lines, Argentina’s brine-based lithium sector is now a strategic wildcard. If proven at scale, it could shift market share away from spodumene producers tied to China—and bring Latin America deeper into the heart of US industrial planning.

Sibanye-Stillwater Withdraws from US Rhyolite Ridge Lithium Project Over Financial Viability Concerns

Sibanye-Stillwater

South African Miner Cancels $490 Million Investment After Reassessing Economic Return of Nevada-Based Lithium-Boron Site

Sibanye Ends US Lithium Ambitions, Exits Ioneer JV Over Project Economics

South African mining company Sibanye-Stillwater has announced it will not proceed with its planned investment in the Rhyolite Ridge Lithium-Boron Project in Nevada. The decision follows a review of updated technical and financial information provided by joint venture partner Ioneer Ltd., based in Australia.

Sibanye stated that the project does not meet its internal rate of return (IRR) thresholds based on prudent lithium pricing assumptions. As a result, the company has scrapped plans to invest $490 million for a 50% equity stake in the lithium project, which was originally signed in 2021.

Rhyolite Ridge Targeted U.S. Lithium Supply Boost

The Rhyolite Ridge project had aimed to produce 20,588 tonnes per year of lithium carbonate and 21,951 tonnes of lithium hydroxide, according to a 2020 definitive feasibility study. Positioned as a major supplier to the U.S. electric vehicle and energy storage markets, the project was viewed as critical to U.S. battery materials independence.

However, rising costs, permitting delays, and shifting market dynamics have pressured several lithium developers to reassess project economics, including those with U.S. strategic significance.

Market Implications and Next Steps for Ioneer

Sibanye’s exit could pose a setback to the U.S. lithium supply chain, especially as automakers and battery makers seek domestic sources. Ioneer has not yet commented on how it will move forward with project financing or timelines. The move highlights broader investor caution in lithium projects amid price volatility and capital intensity.

As lithium markets remain dynamic, miners like Sibanye are recalibrating strategies, prioritizing returns over expansion in a saturated development pipeline.

US Tariffs Could Boost Argentina’s Lithium Salts Production

Argentina Lithium

New Tariff Policies May Propel Argentina to the Forefront of Battery Materials Supply

US President Donald Trump’s new tariff measures, announced this week, could significantly impact the global lithium market. While many energy and mineral products, including lithium carbonate and lithium hydroxide, are exempt from new tariffs, the shift towards more localized battery production in the US could create new opportunities for Argentina's lithium sector. Argentina, with its lower-cost brine assets, could become a key player in the production of battery-grade lithium salts.

Shift in Global Battery Manufacturing and Tariffs Impact

Trump's recent tariff policy introduced significant duties on completed batteries from China, Japan, and South Korea. These duties are likely to accelerate the trend of localizing battery production in the US. Under the Inflation Reduction Act of former President Joe Biden’s administration, the US has already seen a shift toward local manufacturing, with major battery manufacturers like Panasonic, Samsung SDI, Ford, and Toyota planning to open around 10 new battery factories this year.

However, with a lack of domestic mining and processing capacity in the US, the country will increasingly rely on imports for raw materials to meet the demand for battery production. The US currently has only one operating lithium mine, Albemarle's Silver Peak mine in Nevada. Despite producing lithium carbonate and hydroxide, this mine cannot meet the higher purity standards required for battery-grade products needed in electric vehicles (EVs).

Argentina’s Competitive Edge in Lithium Salts Production

Argentina stands out due to its potential to produce high-quality, cost-competitive lithium salts. Brine operations in Argentina are expected to be more efficient and less costly than other South American and spodumene-producing countries. Although brine facilities require higher initial capital costs, their ongoing operational costs are lower than spodumene-based assets, making them an attractive option for global supply chains.

Argentina’s competitive advantage is further strengthened by its 3% royalty tax on lithium mining, compared to the 40% ceiling in Chile, which has a more developed lithium industry. Despite facing a 10% import tariff by the US, Argentina is well-positioned to expand its lithium production to meet the growing demand from battery factories in the US. According to Argentina’s Vice Minister of Energy and Mining, Daniel Gonzalez, "All of Argentina's lithium projects go to battery grade," signaling the country's commitment to producing high-purity lithium products.

While countries like Australia, Brazil, and some African nations rely on China for lithium processing, Argentina's direct production of battery-grade lithium offers it a strategic advantage in the global market.

US New Tariffs Could Disrupt China's Non-Exempt Metals Exports

China Tariffs

New tariffs on lithium, rare earth magnets, and more could affect China's metal exports to the US.

The United States has announced significant new tariffs on Chinese imports, with a notable focus on metals. While many non-ferrous metals and ferro-alloys have been exempted, some crucial exports from China, like lithium, rare earth magnets, and lithium-ion batteries, will face substantial increases in tariff rates. These changes are set to have a lasting impact on the trade between the US and China, especially in the energy storage and electric vehicle (EV) sectors.

High Tariffs on Lithium-Ion Batteries and Energy Storage

As of April 9, the US will implement an 82.4% tariff on electric vehicle (EV) power batteries and a 57.4% tariff on non-EV lithium-ion batteries from China. This substantial hike in tariffs will make Chinese-made batteries far more expensive and may eliminate the possibility of Chinese EV power batteries entering the US market. US consumers will likely absorb these costs, potentially leading to inflation in the US battery industry, especially in the energy storage sector.

China’s lithium-ion battery exports to the US had already been on the rise, with a 59% increase in exports during the first two months of the year. However, these new tariffs are expected to curb the growth of China's battery exports to the US and negatively affect lithium feedstock prices, which are currently at a four-year low.

Impact on Rare Earth Magnets

Rare earth magnets are another key area of concern, as these products were not exempted from the new tariffs. Despite some uncertainty about the exact tariff implementation, producers in China are anxious about the potential 54% tariff on rare earth magnets. China remains the dominant supplier of rare earth magnets globally, and while the US does have some alternatives, they are mostly focused on military applications with significantly higher prices. This makes it unlikely that the US can fully escape its dependence on China, especially for civilian applications.

China’s exports of rare earth magnets to the US in 2022 accounted for 12% of its total exports, and while tariffs could reduce this figure, China’s competitive pricing in the civil sector ensures its continued dominance in the global market.

Copper, Aluminium, and Hafnium: Other Affected Metals

While copper and aluminium are exempt from this latest round of tariffs, the copper industry remains on edge. US authorities are investigating the potential security implications of copper imports, and there’s speculation that a tariff may be imposed in the future. As for aluminium, Chinese exports are already subject to a steep 70% tariff, which is expected to discourage further aluminium exports to the US, pushing Chinese suppliers to seek alternative markets.

Hafnium, a critical metal used in aerospace applications, will also face a significant tariff hike, moving from 34% to 79%. This change could prompt US buyers to source hafnium from other regions, like Rotterdam, where the tariff is considerably lower.

Conclusion

The new US tariffs on Chinese metals exports are set to reshape the global metals market, particularly for lithium-ion batteries, rare earth magnets, and hafnium. While some sectors, like copper and aluminium, may have avoided immediate tariff hikes, long-term implications for the industry remain uncertain. The tariff increase on key metal exports from China to the US is expected to alter supply chains and increase costs for US consumers, especially in the EV and energy storage markets.

ABTC’s Tonopah Flats Lithium Project Secures $900mn EXIM Backing

American Battery Technology Company

Strategic Funding to Accelerate U.S. Lithium Refining Capacity

The Tonopah Flats Lithium Project may receive $900 million in federal support to bolster U.S. lithium supply chains. American Battery Technology Company (ABTC) announced that it received a Letter of Interest (LOI) from the U.S. Export-Import Bank (EXIM), supporting the development of a domestic lithium mine and refinery in Nevada. The proposed facility would produce 30,000 metric tonnes per year of battery-grade lithium hydroxide, a key material for EV and energy storage systems.

Federal Executive Order Boosts Critical Mineral Projects

The EXIM LOI aligns with the March 2025 Executive Order aimed at fast-tracking domestic mineral production. Under this order, agencies like EXIM are directed to prioritize permits, funding, and offtake support for projects vital to U.S. defense and energy security. The Tonopah Flats Lithium Project fits these criteria by offering a scalable, local source of lithium using advanced leaching processes for sedimentary claystone resources.

ABTC Advances with Proven Technology and Industrial Partnerships

ABTC has already proven its lithium extraction technology at pilot scale and is now scaling up with help from engineering partner Black & Veatch. Together, they are working on the commercial refinery’s design and construction, ensuring the Tonopah Flats Lithium Project meets both industrial and regulatory benchmarks for U.S.-based lithium supply.

The Metalnomist Commentary

This funding milestone places ABTC at the forefront of America’s lithium independence strategy. The Tonopah Flats Lithium Project exemplifies how federal coordination and innovative extraction technology can reduce reliance on foreign lithium sources.

Smackover Lithium Arkansas Royalty Proposal Targets 2.5% on Technical-Grade Production

Smackover Lithium

New royalty framework aims to compensate brine owners as lithium extraction scales in Southwest Arkansas

Reynolds Unit Phase 1 application outlines total 3% equivalent compensation package under SWA project

Smackover Lithium Arkansas royalty terms have been formally proposed as the company seeks to establish a standardized payout structure for its South West Arkansas (SWA) lithium project. The U.S.-based lithium developer submitted an application to the Arkansas Oil and Gas Commission, requesting approval for a 2.5% gross royalty on lithium production, calculated quarterly.

Royalty terms include fixed brine lease fee alongside lithium pricing-based compensation

In addition to the gross royalty tied to technical-grade lithium carbonate prices and output volumes, the proposal includes a flat annual “in lieu bromine royalty” of $65.05 per acre. Combined, the package is expected to deliver around 3% total compensation to brine owners at current lithium market levels. The new royalty structure is seen as a potential benchmark for future brine-based lithium developments in Arkansas and the broader Smackover Formation.

Hearings for Reynolds Unit Phase 1 scheduled for late May 2025

The royalty application specifically pertains to the Reynolds Unit, part of Phase 1 of the SWA Project, located in Lafayette and Columbia counties. Regulatory hearings are scheduled for 28 May 2025. This move signals a critical step in aligning mineral rights, community engagement, and scalable extraction operations in a region expected to play a key role in U.S. lithium supply security.

The Metalnomist Commentary

The Smackover Lithium Arkansas royalty proposal reflects a maturing phase in domestic lithium resource development. As U.S. lithium demand intensifies, clear royalty frameworks like this help derisk investment, clarify stakeholder value, and strengthen the social license to operate in emerging lithium basins.

Lithium Americas to Start Thacker Pass Build in May 2025

Lithium Americas to Start Thacker

Lithium Americas confirms Thacker Pass construction start in May, targeting production by late 2027 to boost U.S. lithium supply.

Thacker Pass Lithium Project Set for Major Construction Phase

Lithium Americas (LAC) will begin major construction at its Thacker Pass project in Nevada starting May 2025. The company aims to reach initial production by late 2027, reinforcing its role in North America's lithium supply chain. Engineering progress has already reached 55% and is expected to exceed 90% design completion by year-end.

LAC’s CEO Jonathan Evans emphasized the readiness to move forward after securing funding and partnerships. “Once we declare final investment decision, our team will focus on execution,” Evans said. This milestone follows the finalization of a $2.26 billion Department of Energy (DOE) loan in October 2024.

Funding and Strategy Behind the U.S. Lithium Push

In March 2025, LAC received a $250 million investment from Orion Resource Partners to support Phase 1 development. The DOE loan—secured under the Advanced Technology Vehicles Manufacturing Loan Program—will help build processing infrastructure. Meanwhile, LAC reported a $42.6 million net loss in 2024, up from $5.1 million in 2023, mainly from DOE and GM deal costs.

The Thacker Pass project is one of the most advanced lithium developments in the United States. Its strategic importance has grown amid increasing global demand for EV battery-grade lithium. The project also marks a significant step toward U.S. efforts to reduce reliance on imported lithium, especially from China.

The Metalnomist Commentary

Thacker Pass isn't just a mining project—it’s a cornerstone of U.S. energy security policy. As governments and automakers race toward EV adoption, domestic lithium supply is becoming as critical as oil once was. The Metalnomist will be watching closely as Lithium Americas enters this pivotal execution phase.

Equinor and Standard Lithium Secure $225 Million for US Lithium Extraction Project

Equinor

Norwegian energy giant Equinor and Canadian firm Standard Lithium have received a $225 million grant from the US Department of Energy (DOE). The grant aims to establish a commercial-scale direct lithium extraction (DLE) facility in Arkansas, a critical step toward enhancing domestic lithium carbonate production.

The facility is part of the companies' joint South West Arkansas (SWA) project. Funds will specifically support constructing a processing plant designed to produce lithium carbonate, a key component in battery manufacturing.

Production Timeline and Capacity

Equinor and Standard Lithium anticipate making a final investment decision on the SWA project by the end of 2025. Once approved, the project's first phase of production is set to begin in 2028. Upon completion, the facility will boast an annual production capacity of 45,000 tonnes of lithium carbonate, significantly boosting the US lithium supply chain for battery production.

Rising Interest in Direct Lithium Extraction (DLE)

Direct lithium extraction has become increasingly attractive due to its environmental and operational advantages over traditional brine evaporation methods. Despite brine reservoirs containing approximately 60% of global lithium reserves, conventional evaporation processes only contribute about 35% of lithium production. DLE technology offers a more efficient and sustainable solution, prompting major industry players like Equinor and Standard Lithium to heavily invest in this emerging method.

In May 2024, Equinor committed up to $160 million for a 45% stake in two of Standard Lithium’s projects, including the SWA initiative. Their collaboration commenced operations at a pilot DLE plant in December 2024, marking a significant milestone toward achieving their ambitious production goals.

US Lithium Salt Imports Decline in 2024 Amid Slower EV Adoption

Lithium Mining

Inventory Destocking and Market Shifts Contribute to Lower Import Figures

The United States saw a significant drop in lithium salt imports in 2024, with total imports falling to 16,170 metric tonnes (t), an 11% decrease compared to the previous year. This decline is attributed to a combination of inventory destocking and slower-than-expected adoption of electric vehicles (EVs).

Factors Behind the Decline in Lithium Salt Imports

The drop in imports can be linked to several factors, including price declines and the limited shelf life of lithium salts. As prices fell, US importers consumed lower stocks, adjusting to market conditions. Additionally, the shift towards lithium iron phosphate (LFP) batteries, which favor lithium carbonate over other lithium salts, further contributed to the decreased demand for lithium oxide and hydroxide.

Impact of Lithium Carbonate and Hydroxide Preferences

Imports of lithium oxide and hydroxide saw a dramatic 25% decrease, amounting to just 705 tonnes in 2024. Meanwhile, imports of lithium carbonate, which is crucial for LFP batteries, dropped by 10% to 15,465 tonnes. This change in battery technology preference has driven the demand for lithium carbonate, particularly as more automakers adopt LFP batteries for their EVs.

Source Countries and Global Lithium Supply Chain

Chile and Argentina played a dominant role in supplying lithium salts to the US, accounting for 98% of the total imports. Chile supplied 9,105 tonnes, while Argentina provided 6,779 tonnes. These two countries remain key players in the global lithium supply chain, with their resources being crucial to meeting the US's demand for lithium salts.

ABM Secures Option to Acquire 50% Stake in Carachi Lithium Project

American Battery Materials (ABM) and XTC Lithium have signed a non-binding agreement on Argentina’s Carachi Lithium Project. The partnership gives ABM the option to acquire up to a 50% interest in the project. ABM can form a joint venture once it secures a 10% stake.

The Carachi project is located in Argentina’s Catamarca Province, a region known for rich lithium brine deposits. The deal marks an early-stage collaboration between the US and Australian developers in a key critical materials hotspot. As lithium demand surges, access to Argentine salars becomes increasingly strategic for global battery supply chains.

XTC Expands Footprint Through Caroline Lithium Acquisition

XTC Lithium controls 21.9 km² of lithium assets through its acquisition of Caroline Lithium. This property includes the Carachi project, which now becomes a joint development opportunity. ABM’s entrance reflects growing investor interest in securing long-term lithium supply from Latin America.

Meanwhile, the non-binding nature of the agreement leaves flexibility for both firms to define next steps. This may include detailed exploration plans, resource estimation, and permitting processes in coming quarters. Industry watchers view such early partnerships as necessary to scale projects quickly in competitive jurisdictions.

Strategic Lithium Alliances Gain Momentum

As a result of tightening global lithium supply, cross-border alliances are gaining momentum. US firms are especially active in Argentina, seeking to diversify supply chains away from Asia. With lithium designated a critical mineral by the US government, projects like Carachi are closely watched.

The ABM-XTC deal represents another step in realigning the lithium industry for the energy transition. With careful execution, the Carachi project could become a vital node in the Western Hemisphere’s lithium map.

The Metalnomist Commentary

Strategic cooperation between American and Australian lithium players in Argentina points to growing urgency for regional lithium independence. If realized, Carachi could play a small but meaningful role in easing pressure on global battery supply chains.

California Lithium Project Gains Expedited Permitting Under FAST-41

California Lithium Project

The California lithium project at Hell’s Kitchen has been selected for expedited federal permitting, marking a major step in strengthening the US domestic critical minerals supply chain. The Federal Permitting Improvement Steering Council announced the project’s inclusion under the FAST-41 program, designed to streamline approvals for large-scale infrastructure projects critical to national security.

Federal Backing for US Lithium Production

The Hell’s Kitchen Critical Minerals and Power Project near the Salton Sea will become the first US facility to extract and process lithium using geothermal brine.
