CleanTech Lithium ("CleanTech Lithium" or "CTL" or the "Company")

Host International Academics from University of Atacama

Copiapó, January 25, 2024: In a joint effort to address global challenges and local issues associated with lithium, CleanTech Lithium has hosted a leading international seminar entitled "Lithium: Global Challenges, Local Issues, Decarbonization, Sustainability and Participation". The event, which took place on January 18^th and 19^th at the Universidad de Atacama, brought together renowned international academics and industry leaders to explore the crucial role lithium plays in global decarbonization and the transition to a green economy.

In a context where decarbonization has become an inescapable priority to mitigate the effects of climate change, lithium emerges as an essential component in the transition to cleaner energy sources. The seminar focused not only on understanding the importance of lithium globally, but also on collaboratively addressing the local complexities associated with its extraction, which is a priority for the Chilean government.

An essential part of the event saw the visit of international academics to the CleanTech Lithium R&D Centre in Copiapó where the Company's DLE Pilot Plant is being commissioned (see figure 1). This direct encounter allowed participants to immerse themselves in the Company's approach to​ lithium extraction, highlighting the importance of public-private partnerships to address the complex challenges facing the industry.

Marcela Sepúlveda, Community Relations Manager, CleanTech Lithium, commented: "Collaboration between academia, industry and government is essential to developing sustainable solutions in lithium extraction and its integration into the global supply chain. The presence of international academics at our DLE pilot plant is a testament to our commitment to innovation and transparency in our operations."

Mauricio Lorca, Research Associate at the Universidad de Atacama, mentioned: "Having these spaces for dialogue and listening are extremely valuable. And in that sense, the presence of CleanTech Lithium was very well evaluated. Having this willingness to build dialogue is obviously a step in the right direction."

About CleanTech Lithium

CleanTech Lithium (AIM:CTL, Frankfurt:T2N, OTCQX:CTLHF) is an exploration and development company advancing sustainable lithium projects in Chile for the clean energy transition. Committed to net-zero, CleanTech Lithium's mission is to produce material quantities of battery grade using sustainable Direct Lithium Extraction technology, powered by renewable energy, the Company plan to be the leading supplier of 'green' lithium to the EV and battery manufacturing market.

CleanTech Lithium has four lithium projects - Laguna Verde, Francisco Basin, Llamara and Salar de Atacama - located in the lithium triangle, the world's centre for battery grade lithium production. The two major projects: Laguna Verde and Francisco Basin are situated within basins controlled by the Company, which affords significant potential development and operational advantages. All four projects have direct access to existing infrastructure and renewable power.

CleanTech Lithium is committed to using renewable power for processing and reducing the environmental impact of its lithium production by utilising Direct Lithium Extraction. Direct Lithium Extraction is a transformative technology which removes lithium from brine, with higher recoveries and purities. The method offers short development lead times, low upfront capex, with no extensive site construction and no evaporation pond development so there is no water depletion from the aquifer. www.ctlithium.com
