Aldo Boitano, Chief Executive Officer, CleanTech Lithium Plc., said:

"Achieving DTC eligibility and the graduation to OTCQX Best Market significantly reduces barriers to trade and puts us amongst a group of premium publicly listed companies in the United States. Investors, excited about the Electric Vehicle revolution, will now be able to trade in the Company's ordinary shares in the US and settle in the US.

"We are committed to enhance the visibility and appeal of CleanTech Lithium's stock in North America, recognising the strong demand from investors who see the long-term role of lithium in EV manufacturing.

CleanTech Lithium has three prospective lithium projects - Laguna Verde, Francisco Basin and Llamara - located in the lithium triangle, the world's centre for battery grade lithium production. The Laguna Verde and Francisco Basin projects are situated within basins entirely controlled by the Company, which affords significant potential development and operational advantages. Llamara is the Company's latest greenfield project, which offers material potential upside at a low initial cost. All three projects have direct access to excellent 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 or harm to the local environment.
