Global Lithium Reserves: Where Are the Largest Deposits of Lithium Located?

As the demand for electric vehicles and energy storage solutions accelerates, understanding where the largest deposits of lithium are concentrated has become crucial for industry stakeholders. The worldwide lithium reserve base totals approximately 30 million metric tons as of 2024, with these resources unevenly distributed across just a handful of nations. This geographic concentration creates both opportunities and vulnerabilities in the global battery metal supply chain.

The Four Nations Commanding the World’s Lithium Supply

Supply Dynamics in 2025

Industry analysts project that lithium-ion battery demand will surge over 30 percent year-on-year throughout 2025, driven by the electric vehicle sector and grid-level energy storage deployments. This anticipated explosion in consumption underscores why mapping where the largest deposits of lithium reside matters more than ever.

Chile: The Undisputed Reserve Leader

With 9.3 million metric tons of recoverable lithium reserves, Chile dominates the global landscape. The Salar de Atacama region alone accounts for roughly one-third of planetary lithium reserves, though the country produced 44,000 MT in 2024—not its peak capacity. What distinguishes Chile is that its reserves represent the bulk of what geologists classify as “economically extractable” lithium, a critical distinction when evaluating real-world production potential.

Both SQM and Albemarle operate major extraction facilities within the Atacama salt flat. A significant strategic shift occurred when Chilean leadership moved toward partial industry nationalization, with the state-owned Codelco negotiating controlling stakes in these operations. Recent 2025 bidding rounds for new extraction contracts attracted international consortiums including Eramet, signaling continued capital investment despite price volatility.

Australia: Output Leader Despite Reserve Position

Australia ranks second in reserves at 7 million metric tons but led global production in 2024, yielding more lithium than any other nation. This paradox stems from Australia’s hard-rock spodumene deposits—a different deposit type than Chile’s brines—which support higher annual extraction rates. The Greenbushes mine, jointly operated through Talison Lithium (involving Tianqi Lithium, IGO, and Albemarle), remains a cornerstone producer since 1985.

Emerging research identifies untapped potential beyond Western Australia’s traditional exploration zones. Scientists at the University of Sydney and Geoscience Australia recently completed the first comprehensive lithium soil density mapping, revealing prospective extraction sites in Queensland, New South Wales, and Victoria. These discoveries hint at future production expansion, though current price declines have forced some operators to temporarily scale back development activities.

Argentina: The Third Pillar of the Lithium Triangle

Argentina possesses 4 million metric tons of reserves and produced 18,000 MT last year, ranking fourth globally in annual output. The nation forms part of the “Lithium Triangle” alongside Chile and Bolivia—a geological region containing over half of planetary lithium reserves. The Argentine government has committed substantial capital, pledging US$4.2 billion toward industry expansion.

Recent project approvals demonstrate momentum: Argosy Minerals received authorization to triple production at its Rincon salar facility, while Rio Tinto unveiled plans for a massive US$2.5 billion expansion that would elevate annual capacity from 3,000 to 60,000 MT by 2028. Industry executives highlight Argentina’s enduring cost competitiveness, even during downturns, positioning it as a stable long-term supplier. Roughly 50 advanced mining projects remain under development across the country.

China: Emerging Reserve Giant and Processing Powerhouse

China officially holds 3 million metric tons of reserves while producing 41,000 MT annually—a 5,300 MT increase year-over-year. However, early 2025 media reports indicate China has substantially expanded its acknowledged reserve base, now claiming 16.5 percent of global resources versus the previously reported 6 percent figure. This surge reflects recent discoveries, including a 2,800-kilometer lithium belt in western regions with proven reserves exceeding 6.5 million tons.

Despite these domestic reserves, China imports the majority of its lithium feedstock from Australia, reflecting the nation’s voracious appetite for battery production. China operates most of the world’s lithium-processing infrastructure and manufactures the bulk of global lithium-ion battery cells, making it the critical intermediary in the supply chain. The U.S. State Department has accused Beijing of deploying predatory pricing tactics to eliminate non-Chinese competitors, deliberately suppressing prices to consolidate market control.

Secondary Reserve Holders

Beyond the top four, other nations maintain noteworthy deposits: the United States (1.8 million MT), Canada (1.2 million MT), Zimbabwe (480,000 MT), Brazil (390,000 MT), and Portugal (60,000 MT). Portugal leads Europe’s reserves, producing 380 MT in 2024. As production expands, these secondary holders increasingly function as meaningful contributors to global supply diversification.

Looking Ahead

The concentration of the largest deposits of lithium in a small number of geographies—particularly within the Lithium Triangle—creates structural supply chain risks. However, emerging discoveries and expanding extraction technologies suggest the next decade will see reserve bases broaden geographically. Investment flows, regulatory frameworks, and technological advancement will ultimately determine whether these deposits translate into sustained production growth aligned with battery demand growth.
