CleanTech Lithium has signed options to buy two lithium brine properties on Argentina's Salar de Antofalla for about $1.9 million in staged payments. It is the Chile-focused company's first step across the border, next to an Albemarle exploration project.
At a glance
- The Genoveva and Sal de Litio 1 properties sit about 80 km from CleanTech's Laguna Verde project in Chile.
- CleanTech will pay $525,000 in the first year and $1.4 million more between October 2027 and May 2031.
- The company plans a roughly $500,000 exploration campaign in 2027, aiming for a first resource estimate.
Background
Much of the world's lithium comes from brine, salty water trapped under dry salt flats in the high Andes of Chile, Argentina and Bolivia. Companies pump the brine and extract the lithium. CleanTech Lithium, listed on London's AIM market, is developing projects in Chile using direct lithium extraction (DLE), a process that pulls lithium straight from brine and returns the remaining water underground.
What happened
CleanTech Lithium said on October 8 that it has signed option agreements to buy 100% of two properties, Genoveva and Sal de Litio 1. Both lie in the southern part of the Salar de Antofalla, a salt flat in Argentina's Catamarca province. The company calls the pair its Antofalla project.
The deal costs about $1.925 million in total, paid in stages. CleanTech will pay $525,000 over the first year and a further $1.4 million between October 2027 and May 2031. It will fund the payments from cash it already holds.
Why Antofalla
The Salar de Antofalla covers about 540 square kilometres and sits roughly 3,350 metres above sea level. CleanTech describes it as Argentina's largest undeveloped salt flat. Earlier geophysical surveys on the Genoveva property point to a brine-bearing layer more than 500 metres thick.
The new properties sit next to an Albemarle exploration project, run by the world's largest lithium producer. CleanTech says that project holds 9.5 million tonnes of lithium carbonate equivalent (LCE), the standard unit for comparing lithium deposits. That neighbouring resource gives CleanTech a reference point before it drills.
What comes next
CleanTech plans to explore Antofalla in 2027 with a budget of about $500,000. The aim is a maiden resource estimate under the JORC code, the Australian reporting standard the company uses. Permits for that work are expected to take about six months.
Laguna Verde in Chile stays the company's main focus, chief executive Ignacio Mehech said. Terms for its Chilean lithium operating contract have been agreed and await ratification. CleanTech hopes Antofalla, Laguna Verde and its Viento Andino project can later share infrastructure and a central conversion plant in Copiapó, Chile.
Our read
Outlook: neutral. This is a small, early-stage land deal with no resource yet, so it has no effect on lithium supply for years. It shows juniors are still adding brine ground in the Andes.
What to watch
- Ratification of the operating contract for Laguna Verde, CleanTech's main project in Chile.
- Permits for the 2027 Antofalla exploration campaign.
- Whether 2027 drilling confirms the thick brine layer indicated by earlier geophysics.

Timeline
- 2026-10-08: CleanTech Lithium announces options on the Genoveva and Sal de Litio 1 properties at Salar de Antofalla.
Supply Drivers
Antofalla adds early-stage brine ground beside a large Albemarle resource, but any output is years away.
Government Policies
CleanTech's main project still waits on ratification of its Chilean lithium operating contract.
What could lift prices
- Explorers are still committing money to Andean lithium brine, which points to confidence in long-term demand.
- A low upfront cost of $525,000 lets CleanTech test the ground before larger payments fall due.
What could weigh on prices
- New brine projects across the Andes could add supply later, if they all reach production.
- Antofalla has no resource estimate yet, so its value rests on geophysics and a neighbour's results.
Country impact
| Country | Impact | Reason |
|---|---|---|
| Argentina | Low | A new explorer joins Albemarle on one of Catamarca's large undeveloped salt flats. |
| Chile | Low | CleanTech's planned conversion plant in Copiapó could one day process Argentine brine too. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Lithium Mining | Neutral | A small option deal adds exploration ground but no near-term supply. |
Who gains, who loses
- CleanTech Lithium: It gains a second country and a large salt flat for a small staged payment.
- The property sellers: They receive $525,000 in the first year and up to $1.4 million more by 2031.
- CleanTech Lithium, if drilling disappoints: The payments and exploration budget would be spent on ground without a resource.
Other ways this could play out
- If 2027 drilling confirms the thick brine layer, Antofalla could become CleanTech's second resource after Laguna Verde.
- If the Laguna Verde contract stalls, CleanTech may face pressure to rethink how much it spends in Argentina.
Price risks
- Lithium prices depend on large producers and battery demand, not on early-stage projects like this.
- A string of new Andean brine discoveries could add to longer-term supply expectations.
Technical view
Price is trading below both its 20-period and 50-period moving averages, a bearish alignment.
