Investor Insight
Executing a well-defined project development strategy for its lithium assets and successfully progressing its DLE pilot plant, CleanTech Lithium is poised to become a key player in an expanding batteries market.
Overview
CleanTech Lithium (AIM:CTL,FWB:T2N,OTC:CTLHF) is a resource exploration and development company with four lithium assets with an estimated 2.72 million tons (Mt) of lithium carbonate equivalent (LCE) 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, leveraging direct lithium extraction (DLE) – a low-impact, low-carbon and low-water method of extracting lithium from brine.
Lithium demand is soaring as a result of a rapidly expanding EV market. One study estimates the world needs 2 billion EVs on the road to meet global net-zero goals. Yet, the gap between supply and demand continues to widen. As the world races to secure new supplies of the critical mineral, Chile has emerged as an ideal investment jurisdiction with mining-friendly regulations and a skilled local workforce to drive towards a clean green economy. Chile is already the biggest supplier of copper and second largest supplier of lithium.
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 manufacturers looking to secure a cleaner supply chain.
Laguna Verde is at pre-feasibility study stage, which is due to be delivered by Q4 2024. The project is targeted to be in ramp up production from 2027. Laguna Verde has a JORC resource estimate of 1.8 Mt of lithium carbonate equivalent (LCE) while Viento Andino boasts 0.92 Mt LCE, each supporting 20,000 tons per annum (tpa) production with a 30-year and 12-year mine life, respectively. The latest drilling programme at Laguna Verde finished in June 2024, results from which will be used to convert resources into reserves.
The lead project, Laguna Verde, will be developed first, after which Veinto Andino will follow suit using the design and experience gained from Laguna Verde, as the company works towards its goal of becoming a significant green lithium producer serving the EV market.
CleanTech Lithium’spilot DLE plantin 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 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 also has two prospective exploration assets – the Llamara project and Salar de Atacama/Arenas Blancas project.
Llamara project is a greenfield asset in the Antofagasta region and is around 600 kilometers north of Laguna Verde and Veinto Andino. The project is located in the Pampa del Tamarugal basin, one of the largest basins in the Lithium Triangle.
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 eco-friendly 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.

Key Projects
Laguna Verde Lithium Project
The 217 sq km Laguna Verde project features a sq km hypersaline lake at the low point of the basin with a large sub-surface aquifer ideal for DLE. Laguna Verde is the company’s most advanced asset,
Project Highlights:
Prolific JORC-compliant Resource Estimate: As of July 2023, the asset has a JORC-compliant resource estimate of 1.8 Mt of LCE at a grade of 200 mg/L lithium.Environmentally Friendly Extraction: The company’s asset is amenable to DLE. Instead of sending lithium brine to evaporation ponds, DLE uses a unique process where resin extracts lithium from brine, and then re-injects the brine back into the aquifer, with minimal depletion of the resources. The DLE process reduces the impact on environment, water consumption levels and production time compared with evaporation ponds and hard-rock mining methods.Scoping Study: Scoping study completed in January 2023 indicated a production of 20,000 tons per annum LCE and an operational life of 30 years.
