CleanTech Lithium

Investor Insight

Executing a well-defined project development strategy for its lithium assets and advancing Direct Lithium Extraction (DLE), CleanTech Lithium is poised to become a key player in the supply of lithium carbonate and the global battery market.

Overview

CleanTech Lithium (AIM:CTL,Frankfurt:T2N) is a resource exploration and development company with three lithium assets in Chile, a world-renowned mining-friendly jurisdiction. The company aims to be a leading supplier of ‘green lithium’ to the electric vehicle (EV) market and growing Energy Storage Systems (ESS) market, leveraging direct lithium extraction (DLE) – a low-impact, low-carbon and low-water method of extracting lithium from brine. DLE enables lower grade projects to be economically viable. New projects using this method will be critical to meet the forecasted demand.

Lithium demand is soaring as a result of a rapidly expanding EV market and ESS proposed pipeline of projects. As part of Chile’s National Lithium Strategy, the company’s flagship Laguna Verde has been named one of six salars prioritized for development — positioning CleanTech Lithium as a key private partner in unlocking the country’s lithium potential.

With an experienced team in natural resources, CleanTech Lithium holds itself accountable to a responsible ESG-led approach, a critical advantage for governments and major car and battery manufacturers looking to secure a cleaner supply chain.

Laguna Verde is at pre-feasibility study stage which is to be completed imminently.

In August 2025, Cleantech Lithium acquired 30 additional licenses from Minergy Chile SpA, with the primary objective of increasing the preferential license position within the government-defined CEOL polygon. Based on the acquisition, Laguna Verde now has an updated total resource is 1.9 million tonnes of lithium carbonate equivalent (LCE), at a grade of 174 mg/L lithium, a 17 percent increase from the previous total resource of 1.63 million tonnes of LCE. The asset also boasts 0.84 million tonnes of LCE in the measured and indicated category at a grade of 178 mg/L lithium.

The company is carrying out the necessary environmental impact assessments in partnership with the local communities. The indigenous communities will provide valuable data that will be included in the assessments. The company has signed agreements with three of the core communities to support the project development.

Salar de Atacama/Arenas Blancas comprises 140 licenses covering 377 sq km in the Salar de Atacama basin, one of the leading lithium-producing regions in the world with proven mineable deposits of 9.2 Mt.

CleanTech Lithium is committed to an ESG-led approach to its strategy and supporting its downstream partners looking to secure a cleaner supply chain. In line with this, the company plans to use renewable energy and the innovative DLE process across its projects. DLE is considered an efficient option for lithium brine extraction that makes the least environmental impact, with no use of evaporation ponds, no carbon-intensive processes and reduced levels of water consumption. In recognition, Chile’s government plans to prioritize DLE for all new lithium projects in the country.

CleanTech Lithium’s pilot DLE plant in Copiapó was commissioned in the first quarter of 2024. To date, the company has completed the first stage of production from the DLE pilot plant producing an initial volume of 88 cubic metres of concentrated eluate – the lithium carbonate equivalent (LCE) of approximately one tonne over an operating period of 384 hours with 14 cycles. Results show the DLE adsorbent achieved a lithium recovery rate of approximately 95 percent from the brine, with total recovery (adsorption plus desorption) achieving approximately 88 percent. The Company’s downstream conversion process is successfully producing pilot-scale samples of lithium carbonate . As of January 2025, the Company is producing lithium carbonate from Laguna Verde concentrated eluate at the downstream pilot plant - recently proven to be high purity (99.78 percent).
