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

Commencement of trading on OTCQX® Best Market for North American investors

CleanTech Lithium PLC (AIM:CTL, Frankfurt:T2N, OTCQX:CTLHF), an exploration and development company advancing next-generation sustainable lithium projects in Chile for the EV transition, has now qualified to trade on the OTCQX® Best Market. The Company has been upgraded to OTCQX from the OTCQB® Venture Market.

Today marks the commencement of trading on OTCQX Best Market under the symbol "CTLHF" as the Company has successfully met the high financial standards, best corporate governance practices, and complied with the U.S. relevant securities law. The graduation to the OTXQX Best Market demonstrates the Company's competency and will streamline any investment activity from investors from the United States and Canada.

Aldo Boitano, Chief Executive Officer, CleanTech Lithium PLC, said:

"By qualifying to trade on OTCQX Best Market, CleanTech Lithium welcomes existing and potential investors.  Our qualification for the premium tier on OTC markets, will provide increased liquidity and disclosure for our shareholders and potential new investors.

"Joining the OTCQX Market is a strategic decision as CTL continues to make progress simultaneously across our three projects located in Chile, in the Lithium Triangle. With Chile being the only South American country producing lithium with a Free Trade Agreement with the U.S, the region is a key market on our path to production.

"Interest in battery manufacturing, electric vehicles and the drive to a green economy is developing at a rapid pace and the Inflation Reduction Act in the USA and Canada's 2035 EV mandate is evidence of this. CTL aims to play a significant role in this by supplying cleaner lithium via Direct Lithium Extraction ("DLE") technology and being part of the OTCQX Best Market is an important step towards delivering this."
