The Lithium Triangle in 2026: Direct Extraction Reaches Argentina, Codelco Takes Chile, Bolivia Still Waits

Three countries hold most of the world's known lithium, and as of mid-2026 they're on three visibly different trajectories — and one of them just proved, in its own back yard, that the technology which could reshape all three is no longer a lab demo. Chile finished a years-long legal fight over who controls its flagship deposit. Argentina is not just the only one of the three actually shipping meaningfully more brine-pond tonnes than a year ago — it's also where Eramet brought the first industrial-scale direct lithium extraction (DLE) plant in Latin America online, delivering first battery-grade lithium carbonate on December 24, 2024. Bolivia's ambitious DLE contracts, by contrast, are still sitting in its legislature, where they've been since 2024. I went through the DLE economics, the first industrial-scale plant, and each country's status against primary sources before writing this, because both the "DLE will fix the lithium supply chain" narrative and the country-level headlines have outrun what's actually been verified.

Why brine takes years and DLE takes hours

The foundational document here is Vera et al., published in Nature Reviews Earth & Environment — a paper that reached final form in March 2023 after being accepted on December 20, 2022, a small but real correction to the "2022 paper" framing that circulates in secondary coverage. Its description of conventional brine extraction is stark: brine is pumped into evaporation ponds where more than 90% of the original water content is lost to evaporation over 10 to 24 months, with a roughly four-year ramp before a project reaches full output. Direct lithium extraction — a family of technologies spanning adsorption, ion exchange, solvent extraction, membrane, and electrochemical methods — compresses that timeline to hours or days per extraction cycle, with select technologies recovering more than 95% of available lithium. The catch, per the same survey, is that only about 30% of DLE technologies have actually been validated on real brine rather than synthetic test solutions — this is still a technology in the middle of its field-proving phase, not a solved problem, Eramet's plant notwithstanding.

Goldman Sachs put numbers on the trade-off in its 2023 report "Direct Lithium Extraction: A Potential Game-Changing Technology." DLE operating costs run $2,800-3,600 per tonne of lithium carbonate equivalent (LCE) at 70-90% recovery, against $3,300-4,900/t for ponds at a lower 40-60% recovery. Capital intensity is closer than the opex story suggests, though — DLE runs $26,000-34,000 per tonne of annual capacity versus $23,000-34,000/tpa for ponds — meaning DLE's case rests on speed and recovery rate, not on being cheaper to build.

Chile: the Codelco-SQM fight is over

The Chilean Supreme Court rejected Tianqi Lithium's final appeal on January 26, 2026, confirming completion of the merger between state copper giant Codelco and SQM's Salar de Atacama lithium operation — the country's most consequential lithium-policy decision in years, now legally settled rather than pending. The resulting entity, NovaAndino Litio, is where the reporting genuinely diverges: some sources describe a 50:50 structure in which Codelco holds a "golden share" that gives it operational control starting in January 2031, with SQM running operations until then; other reporting describes Codelco taking a 51% controlling stake immediately upon completion. Both versions appear in credible coverage of the same deal, and a single primary filing that reconciles them wasn't confirmed this session — worth verifying directly against SQM's own 6-K filings before citing a specific ownership percentage as settled. What is confirmed: because the joint venture materialized before the end of 2025, SQM secured a quota increase of 300,000 tonnes of lithium carbonate equivalent through 2030, raising its extraction allowance to 1.65 million tonnes LCE for the remainder of its mining lease.

Argentina: RIGI tonnes, and the DLE plant that proved the technology

Argentina's RIGI (Régimen de Incentivo para Grandes Inversiones) investment-incentive regime is the one part of the Lithium Triangle story with hard 2025 output to point to rather than just announcements — and it now runs alongside a genuinely separate technological milestone in the same country. On the brine-pond side, Lithium Argentina's Cauchari-Olaroz project produced approximately 34,100 tonnes of lithium carbonate for full-year 2025, and in December submitted RIGI and environmental permits for a Stage 2 expansion targeting an additional 45,000 tonnes per year of capacity. Rio Tinto's Rincón project began exports in 2025, reaching 140 tonnes of cumulative production by the end of October that year — a small base, but Rio Tinto's own 2026 guidance calls for 61,000-64,000 tonnes LCE (its share) from the project. Both Rincón and the Cauchari-Olaroz expansion are among the RIGI-approved projects, alongside the Hombre Muerto West lithium project.

Separately, in Salta province, Eramet's Centenario plant — a joint venture with China's Tsingshan structured 50.1/49.9 as Eramine — delivered its first battery-grade lithium carbonate on December 24, 2024. Built for $870 million and completed in under three years, it is the first industrial-scale DLE facility in Argentina, with a 24,000 t/yr nameplate and long-term optionality above 75,000 t/yr. Eramet later moved to acquire Tsingshan's 49.9% stake, taking on a net-debt impact of roughly $699 million in the process. It's not part of the RIGI-tracked pipeline above, but it's the same country, and it's the closest thing the DLE story has to industrial-scale, real-brine proof outside a lab.

Bolivia: still waiting on its legislature

Bolivia's Salar de Uyuni holds some of the largest lithium resources in the world by USGS estimates, but its two flagship DLE contracts — a roughly $1 billion agreement with China's CBC (a CATL subsidiary) and a separate deal with Russia's Uranium One — have been stalled in Bolivia's legislature since late 2024. As of this writing, only the Uranium One agreement has received partial approval; the CBC contract remains unauthorized, with no confirmed timeline. Indigenous communities near the project sites have separately filed legal challenges citing environmental and self-determination concerns over preliminary site activities that began before legislative approval was secured. Any figure describing Bolivia's future DLE output — including commonly cited "by 2030" production targets — should be read as an aspiration tied to contracts that haven't yet cleared Bolivia's own legislature, not a confirmed production plan. Bolivia is, notably, betting entirely on the same still-proving technology Eramet just brought online next door in Argentina — with none of Eramet's three years of construction lead yet even started.

Meanwhile, outside the Triangle: the US Smackover race

The United States is chasing DLE via a different geology entirely — the Smackover Formation brine of Arkansas and Texas — with real federal money behind it. The Department of Energy has committed $450 million split across two DLE projects: ExxonMobil's Saltwerx operation, covering roughly 300,000 net acres and targeting commercial production around 2027-28, and the Standard Lithium-Equinor joint venture, which completed a definitive feasibility study in September 2025, with construction starting in 2026 and commercial output targeted for 2028. Chevron entered the Smackover play on June 17, 2025 with two acreage positions of its own; specific acreage totals attributed to Chevron beyond that entry date could not be independently confirmed and are left out here. Smaller specialist players — Lilac Solutions' ion-exchange technology at the Kachi project, China's Sunresin in adsorption — round out a field that is still mostly pre-commercial outside of Eramet's Argentina plant.

The production and reserves picture, by country

Note the deliberate distinction in that table: "lithium content" tonnes and "lithium carbonate" tonnes are different units, and this piece does not convert between them or between either and LCE — treat any comparison that silently mixes the three as suspect.

The price backdrop

Lithium carbonate priced in China peaked at roughly 597,000 RMB per tonne in November 2022, then crashed more than 80% — CIF North Asia pricing had fallen to about $9,550/t by February 2025 — before rebounding through early 2026. SMM's own H1 2026 market review puts the next peak at CNY 181,000/tonne on January 26, 2026 — the same week as Chile's Supreme Court ruling, coincidentally — before a pullback to roughly CNY 165,000/tonne by late March and trading near $20,684/tonne (CIF China/Japan/Korea terms, Fastmarkets) as of April 1, 2026. A separate CEIC/Benchmark Mineral Intelligence read for the same month put the price closer to 157,400 RMB/t — the two trackers don't match exactly, likely a difference in exact date or grade rather than a real contradiction, and this piece isn't collapsing them into one number.

SMM attributes the rebound to three specific, named causes rather than an unexplained bounce: Zimbabwe's suspension of lithium concentrate exports (removing feedstock from Chinese supply chains), supply discipline among Australian spodumene producers following the 2024 price trough, and a resumption of Chinese battery-producer restocking. SMM's outlook flags persistent shortages continuing into H2 2026, with prices likely to rise further — a forecast, not a locked-in outcome, but one grounded in three identifiable market mechanisms.

China's grip on refining, regardless of who mines

The strategic context sitting above all three Triangle countries' maneuvering is China's continuing dominance of refining rather than mining. The IEA's Global Critical Minerals Outlook 2025, published May 21, 2025, projects that "in 2035, China is set to supply over 60% of refined lithium and cobalt, and around 80% of battery-grade graphite and rare earth elements" — a continuation of processing shares that already run 60-90% today. That's the backdrop that makes faster, Western-controlled DLE production — whether Eramet's in Argentina or ExxonMobil's in Arkansas — strategically significant even before it moves the needle on total supply. On the demand side, Wood Mackenzie's March 3, 2026 lithium outlook — research director Allan Pedersen — states that "under ambitious climate scenarios, we see deficits emerging from 2028," tied to a Net Zero scenario requiring an additional 8.5 million tonnes of LCE and up to $276 billion in investment through 2050. That is a scenario-conditioned forecast, not a base-case prediction, and should be read as one.

The view from Kathmandu

For a country with no lithium reserves of its own, South Asia's exposure to this story runs entirely through price and geopolitics — every battery import carries the cost structure of whichever country and whichever extraction method won out an ocean away. Chile's legal resolution, Argentina's dual-track production (ponds shipping tonnes, DLE now proving the technology), and Bolivia's stalled legislature are, together, the supply side of that equation; the price backdrop above is the other half. If DLE's economics hold up as more projects clear the "tested on real brine" bar that only 30% of the field has cleared so far, the multi-year lag between a lithium discovery and a usable battery could shrink meaningfully — mattering as much for Kathmandu's e-rickshaw fleets and rooftop-solar storage packs as it does for Wall Street's models of a 2028 supply deficit.
