A $3 Billion Argentine Lithium Project Is Hunting a Third Backer

Energy & Commodities · Argentina

—The search. China’s Ganfeng and its Swiss-based partner Lithium Argentina are looking for a third investor to help fund their PPG lithium project in northern Argentina.

—The scale. The project carries more than three billion dollars in planned spending and would eventually produce one hundred and fifty thousand tonnes of lithium a year.

—The timing. Lithium Argentina’s president, Ignacio Celorrio, told Reuters a partner should be chosen in the coming months, but would not name the candidates.

—The asset. PPG sits in Salta province and ranks among the largest untapped lithium-brine deposits anywhere in the world.

—The incentive. The venture is being routed through Argentina’s RIGI regime, the tax-and-tariff sweetener President Javier Milei created to draw big foreign capital.

—Why it matters. The identity of the third backer will hint at whether one of the world’s biggest lithium assets leans further toward China or toward the West.

A giant Argentina lithium project controlled by China is quietly shopping for a third partner, and for investors the interesting question is less about the money than about who gets the seat at the table.

What the Argentina lithium project actually is

The venture is known as PPG, short for Pozuelos-Pastos Grandes, a cluster of salt flats in the high-altitude Salta province of northern Argentina. It was formed by stitching together three neighbouring brine deposits into a single development.

Lithium is the light metal at the heart of the batteries that power electric cars and store renewable energy. Argentina sits in the so-called Lithium Triangle, shared with Chile and Bolivia, which holds the bulk of the world’s known reserves.

PPG is one of the largest untapped brine deposits on the planet. At full tilt it is designed to produce one hundred and fifty thousand tonnes of lithium a year, built out in three equal stages.

Who owns it now

Two players control PPG today. Ganfeng, the Chinese mining group that is one of the world’s biggest lithium companies, holds the larger share, while Lithium Argentina, a company based in Switzerland and listed in New York and Toronto, holds the rest.

The two are not new partners. They already run the producing Cauchari-Olaroz operation together, and have poured close to two billion dollars into the wider Salta assets through purchases and early development.

The current structure was set last year, when the pair agreed to fold three adjoining salt-flat projects into one joint venture. Ganfeng took the controlling stake, reflecting the resources and technology it brought in, with Lithium Argentina holding the balance.

Ganfeng had bought the core Pozuelos block back in 2022 and spent further sums building roads, wells and a large construction camp. The combined deposit holds one of the biggest measured lithium resources of any untapped brine project in the world.

Why bring in a third investor

A project this size is expensive and slow. Spreading more than three billion dollars of cost across three partners eases the burden on any single one and shares the risk of a market where lithium prices have swung hard.

Celorrio said the search is well advanced, with a choice expected within months. He declined to say who is in the running or how ownership would be split.

A third backer often comes with a second prize attached. Such partners frequently sign deals to buy the future output, locking in supply for a carmaker, a battery maker or a trading house.

That makes the search as much about customers as about cash. The right partner brings both a cheque and a guaranteed buyer for the metal the project will eventually pump out.

The Milei incentive behind it

The project is being channelled through RIGI, the large-investment regime that President Javier Milei created to lure foreign money with tax and customs breaks and long-term legal stability. It has already drawn other big mining commitments to Argentina.

The plan envisions an advanced extraction technique and a low running cost per tonne. First production is targeted for around 2029.

Why it matters for investors

The financing question is also a strategic one. Lithium has become a contest between China, which dominates processing, and Western governments trying to build supply chains that do not run through Beijing.

A Western carmaker or fund taking the third slot would read very differently from another Asian buyer. Either way, the choice signals how this corner of the Lithium Triangle is tilting.

For now the asset stays firmly under Chinese control. The coming months will show whether the new money dilutes that grip or simply reinforces it.

Frequently Asked Questions

What is the PPG Argentina lithium project?

PPG, or Pozuelos-Pastos Grandes, is a large lithium-brine development in Salta province in northern Argentina. It is designed to produce up to one hundred and fifty thousand tonnes of lithium a year and is one of the biggest untapped deposits in the world.

Who controls the project?

It is jointly owned by China’s Ganfeng, which holds the majority, and Lithium Argentina, a Swiss-based company listed in New York and Toronto. The two are now seeking a third investor to help fund the more than three billion dollars in planned spending.

Why does the third investor matter?

Lithium supply has become a geopolitical contest between China and the West. Whether the new partner is another Asian group or a Western carmaker or fund will signal which way one of the world’s largest lithium assets is leaning.
