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

Commences Strategic Partnership with The University of Atacama in Chile

CleanTech Lithium PLC (AIM: CTL, Frankfurt:T2N, OTCQX:CTLHF), an exploration and development company advancing sustainable lithium projects in Chile for the clean energy transition, is pleased to announce that the Company has entered into a strategic partnership (the "Partnership") with the University of Atacama (the "University") in Chile. This is the University's inaugural agreement with a lithium-focused company.

The Partnership aims to secure a sustainable and skilled workforce, develop research initiatives and nurture the next generation of lithium industry professionals in the Atacama region. The University is in Copiapó, a historic mining town in the northern part of the Atacama region, and in proximity to CTL's operations office which is in the centre of the town near the regional government offices. The collaboration confirms the shared commitment to support the global clean energy transition while advancing the socio-economic development in the region.

Marcela Sepúlveda, Community Relations Manager, CleanTech Lithium said: "We are delighted to announce this partnership with the University of Atacama, which is a testament to our unwavering commitment to sustainable development, innovation, and the empowerment of the communities in which we operate.

"The partnership is paving the way for a robust and sustainable workforce to produce lithium and will help cement CleanTech Lithium as an industry leader in Chile. We look forward to advancing this collaboration and eagerly anticipate the positive impact this partnership will have on the lithium sector and the Atacama region."

Forlín Aguilera Olivares, Chancellor, University of Atacama, commented: "This signing of the agreement is part of the various initiatives that the University is carrying out to strengthen the lines of action with territorial relevance, and there is no doubt that this includes the development of lithium. We must intensify our efforts to strengthen the generation of knowledge and transfer technologies that contribute to greater environmental protection.

"To contribute, as a state university in the region, to the sustainable development of our productive mechanisms and leverage, so that they can reach a successful conclusion. This agreement is part of these challenges that we have as an institution, so we are very happy to materialise this joint work, this public-private synergy, which is fundamental."
