CleanTech Lithium (LSE:CTL) has produced approximately 330 kilograms of high-purity lithium carbonate from material generated at its Laguna Verde Direct Lithium Extraction (DLE) pilot plant. The lithium carbonate, processed by Empower at its new facility in Dallas, achieved purity levels of up to 99.91%, while a further 250 kilograms remains contained within recycle fluids for future recovery.
The production process incorporates DuPont nanofiltration and boron removal technology, helping the company validate its proposed processing flowsheet while also assessing opportunities to improve project economics through the recovery of valuable by-products.
Optimisation programmes support next phase of project development
CleanTech Lithium is progressing several technical studies aimed at enhancing the performance and efficiency of the Laguna Verde project ahead of its Definitive Feasibility Study (DFS).
Current work includes a process validation programme with Lanshen in Chile as part of the Pre-Feasibility Study (PFS), benchmarking of DLE adsorbent technology in France, and a brine reinjection study being carried out with Zelandez.
These initiatives are intended to optimise lithium recovery, ensure the project consistently meets battery-grade product specifications and develop sustainable brine reinjection solutions to support long-term environmental performance.
Technical work strengthens project investment case
By refining its processing flowsheet and advancing engineering studies, CleanTech Lithium aims to improve the commercial attractiveness of the Laguna Verde project for future strategic partners, customers and investors.
The company believes the latest production results and ongoing optimisation work will strengthen the project’s readiness for the DFS while supporting discussions with potential offtake partners seeking high-purity lithium products for electric vehicle and battery supply chains.
Financial outlook reflects development-stage profile
As a pre-revenue development company, CleanTech Lithium continues to report operating losses and negative free cash flow while investing in project advancement. Technical indicators also remain weak, with the shares trading below key moving averages and momentum measures remaining negative.
Valuation metrics provide limited support due to the company’s loss-making position and the absence of a dividend, making direct comparisons with established producers more challenging.
