Global Lithium Supply Landscape: Where the World's Largest Lithium Reserves and Mines Are Located

The global pivot toward clean energy has made lithium an increasingly critical commodity. As electric vehicle production accelerates and renewable energy storage expands, demand for this “battery metal” continues to surge. According to industry analysts, lithium demand tied to EVs and energy storage systems is projected to rise over 30% annually through 2025. Understanding which countries control the world’s largest lithium deposits and operate the largest lithium mines becomes essential for investors and energy planners alike.

Globally, lithium reserves total approximately 30 million metric tons as of 2024, according to the US Geological Survey. However, these reserves are highly concentrated geographically, with four nations controlling more than two-thirds of the world’s supply. This concentration creates both opportunities and vulnerabilities in the global supply chain, particularly as international demand continues its upward trajectory.

Chile Dominates: Home to the Largest Lithium Mine Foundation in the Salar de Atacama

When discussing the world’s largest lithium reserves and mines, Chile commands center stage. The South American nation accounts for 9.3 million metric tons of reserves—nearly 31% of the global total. The country’s dominance centers on the Salar de Atacama region, which alone represents approximately one-third of all identified lithium resources worldwide. This vast salt flat hosts some of the largest lithium extraction operations globally.

Chile’s lithium landscape is shaped by two heavyweight producers: SQM and Albemarle, both operating major extraction facilities in the Atacama region. Together, these companies have established operations that rank among the most productive lithium mines on the planet. In 2024, Chile produced 44,000 metric tons of lithium, securing its position as the world’s second-largest producer despite controlling the largest reserve base.

The country’s strategic approach to its lithium wealth took a significant turn in April 2023, when Chilean President Gabriel Boric announced a partial nationalization strategy aimed at strengthening state control over lithium extraction. Under this framework, the state-owned mining company Codelco has negotiated expanded stakes in both SQM and Albemarle’s Atacama operations, positioning itself for greater influence over future development. This reflects a broader trend of resource nationalism in the lithium sector, where governments seek greater control over extraction and revenue distribution.

Regulatory constraints have historically limited Chile’s ability to expand its global market share despite its vast mineral wealth. A 2025 bidding round for lithium operation contracts across six salt flats attracted international interest, including participation from Eramet, Quiborax, and Codelco. This competitive process signals Chile’s intent to modernize its licensing framework while maintaining national oversight of its most valuable resource.

Australia’s Greenbushes and Hard-Rock Advantage: The Largest Lithium Mine Operations by Production Scale

Australia presents a different lithium supply profile. With 7 million metric tons in reserves, the country ranks second globally in total resources. Despite holding fewer reserves than Chile, Australia emerged as the world’s largest lithium producer in 2024, reflecting the efficiency and scale of its mining operations.

Australia’s lithium deposits differ fundamentally from Chile’s: they exist primarily as hard-rock spodumene deposits rather than salt brine formations. This geological distinction shapes extraction methods and operational economics. Western Australia dominates production, with the Greenbushes mine standing as a premier operation in the global landscape. Managed through a joint venture involving Talison Lithium, Tianqi Lithium, and Albemarle, Greenbushes has maintained continuous production since 1985 and ranks among the world’s largest lithium mines by output volume.

Recent market pressures have forced adjustments in Australian lithium strategy. A sharp decline in lithium prices during 2024 and early 2025 prompted several producers to curtail or temporarily suspend operations, awaiting improved market conditions. However, new research published in 2023 by University of Sydney scientists and Geoscience Australia identified previously unmapped lithium concentrations across Queensland, New South Wales, and Victoria, suggesting substantial untapped potential beyond Western Australia’s current dominance.

Argentina and China: Ascendant Players Reshaping the Lithium Supply Chain

Argentina controls the third-largest reserves globally at 4 million metric tons, positioning it as part of the “Lithium Triangle” alongside Chile and Bolivia—a region collectively hosting more than half of the world’s identified lithium resources. The nation produced 18,000 metric tons in 2024 and has implemented aggressive expansion plans. In 2022, the Argentine government committed $4.2 billion to lithium sector development over three years. More recently, projects like Argosy Minerals’ Rincon operations have received government approval to expand production from 2,000 MT to 12,000 MT annually. Mining giant Rio Tinto announced a $2.5 billion investment in 2024 to dramatically scale its Argentine operations, with capacity increases from 3,000 to 60,000 MT beginning in 2028.

China rounds out the top four with 3 million metric tons in reserves. The Asian nation’s lithium profile combines multiple deposit types—brines, spodumene, and lepidolite deposits. In 2024, China produced 41,000 metric tons, marking a 5,300 MT increase year-over-year. Remarkably, despite this significant domestic production, China still imports most of its lithium from Australia to fuel its massive battery manufacturing and electric vehicle industries.

China’s market influence extends beyond production volumes. In October 2024, the US State Department accused Beijing of pursuing predatory pricing strategies—deliberately flooding the global market with low-priced lithium to eliminate non-Chinese competitors. Chinese media reported in early 2025 that national discoveries had substantially increased proven reserves, now representing 16.5% of global resources compared to 6% previously. A newly identified 2,800-kilometer lithium belt in western China contains verified reserves exceeding 6.5 million tons of lithium ore, with potential resources surpassing 30 million tons. Advances in extracting lithium from salt lakes and mica deposits have further expanded China’s supply profile.

Secondary Reserve Holders and Market Dynamics

Beyond the leading four nations, additional lithium resources exist in Canada (1.2 million MT), the United States (1.8 million MT), Brazil (390,000 MT), Zimbabwe (480,000 MT), and Portugal (60,000 MT). Portugal notably controls Europe’s largest reserves. As production capacity expands worldwide, these secondary producers increasingly contribute to global supply diversification.

The Strategic Imperative: Why Lithium Reserve Distribution Matters

The geographic concentration of the world’s largest lithium mines and reserves in specific countries creates strategic dependencies. With over 66% of global reserves controlled by just four nations, supply chain security has become a central concern for industrialized economies. Battery metal demand is projected to accelerate as electric vehicle adoption expands and grid-scale energy storage becomes increasingly essential to renewable energy infrastructure.

Competition for lithium resources is intensifying through direct investment, strategic partnerships, and political maneuvering. Countries without substantial domestic reserves are securing long-term supply contracts and funding exploration projects in resource-rich nations. Simultaneously, resource-holding countries like Chile and Argentina are reasserting state control to maximize economic benefit from their mineral wealth.

Looking ahead, the lithium sector will be shaped by technological innovations in extraction and processing, geopolitical rivalries over supply access, and the accelerating global transition to clean energy technologies. Understanding where the largest lithium reserves and mines operate provides critical insight into the future energy economy and investment landscape.
