Cleantech Lithium — Chile Day in London

(AIM:CTL, Frankfurt:T2N) CleanTech Lithium PLC, an exploration and development company advancing sustainable lithium projects in Chile, attended Chile Day in London, where the Minister of Economy and Mining, Daniel Mas, confirmed during his speech that the Special Lithium Operating Contract (CEOL) for Laguna Verde, the company’s flagship project, is currently with the Comptroller General’s Office for final review. CleanTech Lithium engaged directly with the Minister regarding the regulatory pathway for Laguna Verde and Chile’s broader ambitions for its lithium sector. The Minister emphasized the crucial role of the private sector in achieving these ambitions. Ignacio Mehech, Chief Executive Officer of CleanTech Lithium PLC, stated that it was very positive to hear the Minister confirm the CEOL for Laguna Verde is under final review by the Comptroller's Office. He described the Minister's comments as encouraging, especially as Chile seeks to expand its lithium industry and foster a supportive environment for private sector investment. CleanTech Lithium will update the market on the CEOL ratification as soon as possible. In the meantime, the company continues critical work, including optimisation test work, preparations for a proposed ASX dual-listing, the Environmental Impact Assessment (EIA), and discussions with potential strategic partners. CleanTech Lithium aims to be part of Chile’s investment case as it advances Direct Lithium Extraction (DLE) brine-based projects in the region. The company has two key lithium projects in Chile, Laguna Verde and Viento Andino, as well as an exploration stage project in Arenas Blancas (Salar de Atacama), located in the lithium triangle. CleanTech Lithium and the Mining Ministry in Chile have agreed on the contractual terms for the CEOL for Laguna Verde, subject to final ratification. The company is committed to utilising Direct Lithium Extraction with reinjection of spent brine. Direct Lithium Extraction is described as a transformative technology that removes lithium from brine with higher recoveries, short development lead times, and no need for extensive evaporation pond construction.
