The US Export-Import Bank plans to commit up to $7 billion toward critical minerals and energy projects in Argentina, with the package set for announcement at the United Nations General Assembly in New York; the funds will enable companies operating in Argentina to obtain loans for American-manufactured equipment, with Argentina's mining minister projecting fivefold lithium and copper export growth by 2036 relative to 2025 levels, while a bilateral trade and investment deal agreed in February, which included critical minerals cooperation, awaits ratification by Argentina's Congress.

Korea Zinc unveiled Project Crucible in Tennessee, a proposed $7.4 billion integrated smelter and critical minerals processing facility targeting 12 nonferrous metals — 11 designated as US critical minerals — with production scheduled to begin in 2029; the US Department of Commerce committed up to $210 million in funding, while the Department of Defense and financial institutions are arranging up to $4.7 billion in debt financing, and the US government took a 10.59 percent equity stake in Korea Zinc through a government-led joint venture, with the project also becoming the first FAST-41 permitting case of its kind.

Tungsten West signed an eight-year offtake with US-based Elmet Technologies for 1,000 tonnes of contained tungsten annually from its Hemerdon mine in Devon, with an indicative nominal value exceeding £1.4 billion at current prices; the binding supply agreement also allows Elmet to process an additional 500 tonnes per year at Tungsten West's request to support UK government and industry needs, and shares rose 8% on the announcement. In Australian tungsten, Tungsten Mining secured a $50 million placement to advance its Watershed project in Far North Queensland toward a final investment decision, with a definitive feasibility study targeted for October and first production planned for the first half of 2027. Great Western Mining completed a 23-hole RC drilling campaign at its Defender Tungsten Project in Nevada, with geological logging and shortwave ultraviolet inspection confirming broad scheelite-bearing skarn intercepts across three target areas; assay results will underpin a maiden mineral resource estimate by Addison Mining Services.

At the AusIMM Critical Minerals Conference in Brisbane, AusIMM chief executive Stephen Durkin argued that trust and STEM capability are central to Australia converting its resource base into durable global supply chain positions, while engineering consultancy GHD's critical minerals lead highlighted that midstream processing value uplift need not target glamorous end products, noting that reagent supply — including sulphuric acid — can be a decisive constraint for project viability.

A forum co-hosted in Canada examined how the country can accelerate the path from discovery to production, identifying faster and more coordinated project delivery as the central challenge in realizing Canada's critical minerals potential. Separately, an analysis of emerging-market positioning argues that re

Copper prices surged on September 22, with Comex copper rising 3.3% intraday to US$6.841 per pound and three-month LME copper reaching US$14,710.50 per metric ton, placing both contracts within 2% of record highs. The primary driver is a 600,000-tonne 2026 supply reduction stemming from unplanned disruptions at Freeport-McMoRan's Grasberg operation in Indonesia and Ivanhoe Mines' Kamoa-Kakula complex in the Democratic Republic of Congo, making 2026 the first year of declining global copper mine production since 2017. On LME exchanges, on-warrant inventory fell to 133,725 tonnes out of total warehouse holdings of 255,900 tonnes, with a further 115,450 tonnes — representing 45% of total stocks — already tied to cancelled warrants and scheduled for withdrawal. The cash market shifted sharply, with LME cash copper moving from an US$86-per-tonne discount to a US$26-per-tonne backwardation within a single week, signaling strong buyer preference for prompt delivery. Comex warehouses hold 696,204 tonnes, but storage at the Port of New Orleans is described as largely full, and Comex stocks posted their first weekly decline since April. Regional tightness is also evident in China, where the Yangshan premium reached US$124 per tonne — a near four-year high — before easing slightly to US$119 per tonne, reflecting active Chinese competition for seaborne supply.

On the infrastructure and energy side, the SMM Africa Critical Minerals Conference 2026 concluded in Lusaka, Zambia, where Huawei presented its mine microgrid solution and held talks with ZESCO, Zambia's national power utility, covering mine energy supply, new-energy deployment, and collaborative power-infrastructure development. Huawei outlined a three-step sustainability framework — green electricity supply, mining equipment electrification, and AI-driven production optimization — and described its IPP-PPA microgrid model as a mechanism for reducing diesel costs and carbon emissions at African copper and cobalt mining sites while supporting Zambia's local ore-processing strategy.

Cirba Solutions and General Motors have completed a closed-loop battery recycling pilot in which end-of-life GM EV packs were disassembled at Cirba's Ohio facility, processed into Black Mass, and refined into cathode active material composed entirely of 100% recycled nickel, cobalt, manganese; Ultium Cells subsequently used that material to manufacture new battery cells, which GM assembled into packs at Factory ZERO and Spring Hill, with the first consumer EVs produced from fully recycled CAM now reaching the market. The partners note that nearly 14 million EV batteries are projected to reach end-of-life globally by 2040, underscoring the scale of opportunity for domestic closed-loop processing to reduce dependence on newly mined critical minerals across battery, energy storage, and data-centre applications.

On the materials-science front, researchers in India have developed a MOF-derived CoFe₂O₄/polyaniline hybrid nanocomposite that performs a dual photocatalytic and electrochemical role, achieving 94 percent degradation of the antibiotic ciprofloxacin within 90 minutes of visible-light irradiation while delivering a power conversion efficiency of 8.53% as a platinum-free counter electrode in a dye-sensitized solar cell. The material's performance derives from a specific surface area of 112.7 m²/g and a reduced band gap of 1.56 eV inherited from its MOF-templated porous architecture, enabling broad visible-spectrum light harvesting and the generation of reactive oxygen species that break down pharmaceutical contaminants.

A battery energy storage system at a Metropolitan Water District facility in La Verne, California triggered a significant incident on Tuesday when a lithium-ion battery fire caused an explosion, injured one civilian, prompted mandatory evacuations across surrounding neighborhoods, and forced shelter-in-place orders at multiple schools including Bonita High School and Grace Miller Elementary; the University of La Verne canceled all classes for the day, and authorities monitoring a second adjacent storage unit kept evacuation orders overnight due to unpredictable thermal behavior, while the MWD confirmed its water supply was unaffected; evacuation orders were eventually lifted after crews gained control. Separately, the Honolulu Fire Department determined that a Waikiki nightclub fire resulted from thermal runaway in a charging lithium-ion battery, causing an estimated $1.9 million in damages, and fire officials in South Bend, Indiana issued warnings after a recycling truck fire was traced to an improperly discarded lithium-ion battery, while departments in answering the Call: Shreveport Fire and horry County fire officials warn issued public guidance on charging safety and thermal runaway risks.

On the corporate development front, the Supreme Court of Western Australia has cleared the Scheme Booklet for European Lithium's all-share acquisition by Critical Metals Corp, scheduling a shareholder vote for 22 October with NASDAQ listing of new Critical Metals shares targeted for 6 November; the independent expert rated the swap not fair but reasonable for ordinary shareholders, while the independent board committee recommends approval. UAE-based Titan Lithium has proposed an A$330 million acquisition of Global Lithium Resources, subject to shareholder and regulatory approvals, with the deal including project development finance to advance the Manna lithium project in Western Australia. Vulcan Energy is building a China-free supply chain with VULSORB output commencing in Germany while seeking backers for its Ludwig project, though its stock sits near its 52-week low. Lithium Americas' Thacker Pass project is transitioning from planning to execution, with the stock posting a 7.65% seven-day return despite trading at a 0.8x price-to-book ratio well below sector peers. Lithium Argentina's balance sheet risk has declined following Ganfeng financing, though dilution risk remains as growth funding requirements persist. The September 2026 junior lithium miner digest notes that China lithium prices are sliding as a key mine loses its licence, while Benchmark Mineral Intelligence has flipped its 2027 supply-demand outlook to a deficit.

In supply-chain and processing developments, Tesla has produced its first Cybertruck using 4680 cells containing lithium refined at its own Gulf Coast facility in Robstown, Texas, employing an acid-free alkaline leaching process that the company claims reduces emissions by approximately 30% and reagent costs by 60%, marking the first instance of a major automaker refining lithium in-house. EMP Metals has completed commissioning of its Project Aurora facility in Saskatchewan, which now operates as a fully integrated continuous-flow direct lithium extraction demonstration plant processing 10 m³ per day of raw brine, with partner Saltworks Technologies advancing design of a modular commercial refinery targeting over 3,000 tonnes per year; the Saskatchewan demonstration plant is designed to simplify brine refining and reduce costs compared with conventional systems. Century Lithium has announced plans to develop a commercial-scale chlor-alkali plant targeting 300 short tons per day of chlorine output to serve the western US critical minerals supply chain, with eight non-binding offtake MOUs already signed and non-dilutive project-level financing under development; the CEO indicated a construction decision within a year is targeted, with permitting expected to be straightforward given the use of an existing infrastructure site. Urban mining firm Bridge Green Upcycle has signed an eight-year lithium carbonate deal with Hartree Partners valued at $500 million to $1 billion, granting Hartree exclusive marketing rights for approximately 10,000 metric tonnes per year of lithium carbonate, with Hartree also making an equity investment to fund expansion of battery recycling operations.

On the technology and research front, Panasonic Energy has opened Energy Innovation Square in Kadoma, Osaka, a 500-employee lithium-ion battery R&D hub that, combined with the Suminoe Production Development Facility, forms one of Japan's largest dedicated battery development operations with a combined workforce of approximately 800, targeting doubled development efficiency by FY2031. Researchers at Southwest Research Institute have developed an Electrical Interchangeability Index to quantify whether sodium-ion batteries can substitute for lithium-ion cells in specific duty cycles without requiring product redesign, identifying high-equivalence and low-equivalence operating regions across charging, discharging, voltage, and power-tracking parameters. The global lithium battery thermal insulation market is projected to more than triple by 2035, driven by grid storage deployment and tightening thermal runaway safety regulations, with East Asia currently hosting over 75% of global production capacity. Bradda Head Lithium has called its 2026 Annual General Meeting for 27 November in Douglas, Isle of Man, with the North America-focused developer advancing its Basin and San Domingo projects in Arizona.

The proposed Pax Silica hub at New Clark City in Tarlac is a 1,620-hectare development designed to attract investment in semiconductors, artificial intelligence, critical minerals, and advanced manufacturing, with the Bases Conversion and Development Authority promoting it as a major industrial and technology hub capable of boosting domestic job creation. Officials have indicated the project would require approximately 65 million to 90 million liters of water and 3 gigawatts of power daily. Caritas Philippines president Bishop Gerardo Alminaza issued a formal call for broader consultation on the project, stating that the initiative appears to be advancing too rapidly and without sufficient study of its effects on affected communities, particularly indigenous Aeta populations. Alminaza demanded clearer information on the project's potential impact on land, water, the environment, and surrounding communities, warning that requirements of such scale demand serious public scrutiny in a country already contending with water stress, energy insecurity, and climate vulnerability, while affirming that the Church does not oppose technology or investment but insists that progress must not sacrifice land, water, culture, or human rights.

At the international level, the United States and Italy signed a critical minerals MOU in New York, with US Secretary of State Marco Rubio and Italian Foreign Minister Antonio Tajani formalizing the Memorandum of Understanding on Cooperation in the Critical Minerals Sector, a move framed as part of a broader Western effort to counter China's dominance in extraction, refining, and processing. Italy's agreement follows a similar accord with Argentina. Industry analysis holds that the memorandum's value depends on its translation into concrete projects, offtake agreements, and investments, with instruments such as Italy's export credit agency SACE and state investor Cassa Depositi e Prestiti identified as mechanisms to finance mining and refining projects abroad and secure long-term production shares. The analysis further notes that Chinese state-supported pricing continues to undermine the financial viability of Western alternative projects, making transparent price-setting mechanisms a prerequisite for building a credible supply-chain architecture. The connection to Pax Silica is framed through supply-chain security logic: without gallium, germanium, graphite, rare earths, and related strategic materials, semiconductors, data centers, power grids, and defense systems — the precise industrial categories Pax Silica targets — cannot be sustained, meaning mineral and cybersecurity integration is considered essential to making the broader initiative credible.

The formal signing at the United Nations General Assembly of a U.S.-Denmark-Greenland security pact has moved Arctic critical-minerals development from concept toward policy, with provisions designed to bar U.S. adversaries from sensitive investments in Greenland and to place Arctic security under NATO oversight. Greenland Mines Ltd. (Nasdaq: GRML) positioned its Sarfartoq and Skaergaard projects as direct beneficiaries of the arrangement; Sarfartoq's Initial Assessment carries a high-case pre-tax NPV of approximately $2.05 billion and planned annual NdPr oxide production equal to roughly 34% of all NdPr oxide currently refined outside China, while the Skaergaard palladium-platinum-gold system holds 15.0 million contained palladium-equivalent ounces in the Indicated category. Separately, the company applied to more than double its exploration footprint across the known rare earth and carbonatite district in West Greenland, and Greenland Mines completed the acquisition of Sarfartoq from Neo Performance Materials for US$35 million — US$20 million in cash and US$15 million in shares — with Neo retaining an equity interest and offtake rights for up to 60% of future ore or concentrate. Greenland Mines also seeks to more than double its Sarfartoq exploration footprint through a newly submitted licence application.

Equity markets reflected the security-deal euphoria and its limits. Shares of Critical Metals Corp. (Nasdaq: CRML), whose flagship Tanbreez deposit in southern Greenland is one of the world's largest known rare earth accumulations, fell 6% on profit-taking after a sharp Monday rally, while USA Rare Earth (Nasdaq: USAR) slipped 2% and MP Materials (NYSE: MP) eased 2%; the VanEck Rare Earth and Strategic Metals ETF (REMX) was essentially flat, confirming the selloff as name-specific rather than a broad rare-earth repricing. Clear Street maintained a Buy rating and $20 price target on CRML, arguing that a formal agreement could accelerate investment and development phases at Tanbreez. Attention also turns to an expected Trump-Xi meeting later this week, where critical mineral supply terms are expected to feature in wider trade discussions.

The supply-security drive extended into national policy and new leasing activity. The Texas General Land Office signed two hard-mineral leases with El Paso Minerals Corp. covering more than 1,000 acres in Hudspeth County, forming the foundation of what officials describe as Texas's first dedicated rare earth mining district; the leases tie into the Round Top Mountain Project, which secured $1.6 billion in federal funding after agreements with USA Rare Earth and the U.S. Department of Commerce in June. India approved an $800 million plan to boost domestic rare earth magnet production and cut import dependence, while Indian producer Lohum simultaneously pursues nickel mine acquisitions in Indonesia and the Philippines as part of a tenfold production expansion. South Korea finalized its first Resource Security Master Plan, which adds ten rare earth elements to the country's critical minerals designation list, expanding the managed roster from 38 to 51 types; stockpile targets for supply-chain-vulnerable minerals will rise to a maximum of 365 days, and a dedicated critical minerals stockpile base will be built at Saemangeum by 2028, with the broader resource security plan also targeting reduction of Middle East crude dependence to below 50% by 2035.

On the corporate and technology front, Leading Edge Materials secured a 25-year exploitation concession for its Norra Kärr heavy rare earth project in Sweden, increased its stake in the Bihor Sud joint venture to 90%, closed the first tranche of a private placement raising just over $4 million, and narrowed its quarterly net loss to $882,239 for the period ended July 31, 2026. ReElement Technologies dispatched representatives to New York for Climate Week and the UN General Assembly to advance rare earth refining partnerships, connecting global mineral resources and recycled feedstocks with its modular chromatography-based separation platform. A research consortium led by Worcester Polytechnic Institute received a $3.3 million NSF grant for a five-year study applying biological mechanisms of diatoms, sponges, and plants to recover rare earth elements from coal ash, red mud, and mine tailings. The IEA context underpinning all of these moves remains stark: demand for the four magnet rare earths has doubled since 2015 and is forecast to grow by another third by 2030, while existing and planned projects outside China would cover only about 50% of 2035 mining demand and well under 20% of magnet demand, leaving a capital gap estimated at approximately $60 billion.
