Major Milestone Achieved: Pilot-Scale Lithium Carbonate Production


CleanTech Lithium PLC (AIM: CTL), an exploration and development company advancing sustainable lithium projects in Chile, is pleased to announce the downstream conversion process is successfully producing pilot scale samples of lithium carbonate. CTL is a leader in Chile in producing lithium carbonate using Direct Lithium Extraction ("DLE") at the pilot scale, marking a major milestone for the Company. The samples will be sent to a laboratory to confirm the grade and impurity profile, which is expected to be battery-grade and prepared for strategic partner qualification.

The Company shipped four tanks with a total of 88m3 of concentrated eluate from its DLE pilot plant in Copiapó, Chile, to the facilities of Conductive Energy in Chicago, USA, for conversion into lithium carbonate. The first tank with 20m3 of eluate is currently being processed and produced the first 50kg of lithium carbonate on November 19th. The full tank will be processed over the next week and is expected to produce approximately 150kg of battery grade lithium carbonate.

To mark the commencement of production a site visit to the conversion facility was held showcasing the innovative process. The conversion process utilises forward osmosis at the concentration stage rather than the conventional evaporator helping to reduce water consumption and energy use before solution purification and then carbonation into the final product.

Conversations with potential strategic partners interested in testing the product have begun. After laboratory analysis, the Company will be aiming to send samples of battery-grade lithium carbonate to such partners initially in the several kilograms to tens of kilograms, to start the product qualification process.

Highlights:

· CTL has produced pilot scale lithium carbonate from Laguna Verde brine following successful commencement of the downstream conversion process

· CTL is a leader in Chile producing lithium carbonate at the pilot scale using sustainable DLE which, with spent brine reinjection, prevents aquifer depletion and through innovative downstream processing, minimises water and energy consumption

· Lithium carbonate product will be sent to a laboratory in North America to be verified as battery-grade (>99.5%)

· A site visit to Conductive Energy's conversion facility took place on Tuesday 19th November to mark the commencement of production from what is the largest pilot plant in operation in North-East USA.

· Conversations with strategic partners have started and samples will be available for product qualification

Steve Kesler, Executive Chairman and Interim Chief Executive Officer, CleanTech Lithium PLC, said:

"CleanTech Lithium has reached an important milestone by commencing pilot scale lithium carbonate production using a sustainable and innovative DLE based process. As a leader in the DLE sector in Chile with a focus on efficiency and sustainability, this accomplishment marks a significant step forward. Years of hard work have led to this important milestone, and it sets the stage for future development with a commitment to supporting the transition to electric vehicles and clean energy. Thank you to the partners involved and we look forward to enter the next phase of development."

Haafiz Hasham, Chief Executive Officer, Conductive Energy, said:

"The successful conversion to lithium carbonate in partnership with CleanTech Lithium and Forward Water Technologies represents a significant milestone for all the companies involved. This achievement highlights our commitment to developing innovative, efficient, and sustainable processes that meet the growing global demand for lithium, a critical component in green energy solutions. We are excited to continue advancing Direct Lithium Extraction, which we believe represents the future of battery-grade lithium production."

Chris Berry: The West Must Invest in Refinement Now or Fall Further Behind

China’s grip on the battery metals sector has drawn increasing scrutiny in recent years as nations confront growing concerns around supply chain risk and resource security.

Through a blend of domestic output and aggressive overseas investment, particularly in Africa and South America, Chinese companies now command a significant share of upstream supply.

The country is responsible for roughly 60 percent of global rare earths production and controls over 70 percent of cobalt supply through its stakes in mines across the Democratic Republic of Congo.
