The Green Achievement Grand Prix award recognises CTL's integrated and comprehensive approach to Environmental, Social, and Governance (ESG) practices, prioritising environmental stewardship, community engagement, and the responsible use of resources.

Marcela Sepúlveda, Community Relations Manager of CleanTech Lithium, said, "We are honoured to win this award which recognises CTL's commitment to producing battery-grade lithium in Chile with a uniquely sustainable ESG approach embedded throughout our business. We believe lithium production should be as green as the electromobility solution it is intended to enable.

"Our approach is aligned with Chile's National Lithium Strategy, from sustainable extraction utilising Direct Lithium Extraction technology to putting the rights of communities at the heart of our decision-making. We recently announced our alliance with the Colla territorial communities for the first co-created mining model for lithium extraction in Chile and we look forward to maintaining this momentum into 2024."

About CleanTech Lithium PLC

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' close to zero carbon 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.
