[{"type":"text","content":"\n\n22 July 2024\n \nCleanTech Lithium PLC (\"CleanTech Lithium\", \"CTL\" or the \"Company\")\nDLE Pilot Plant First Stage Production Completed, Downstream Process Optimised\nwith Sample of Battery-Grade Lithium Produced\n \nCleanTech Lithium PLC (AIM:CTL, Frankfurt:T2N, OTCQX:CTLHF), an exploration and development company advancing sustainable lithium projects in Chile, announces completion of the first stage of production from the Company´s DLE pilot plant operations and results from successful downstream process test work to produce battery-grade lithium carbonate by process partners in North America.\nHighlights:\n· An initial volume of 88m3 of concentrated eluate, which is the lithium carbonate equivalent (LCE) of approx. one tonne, has been produced from the Company´s DLE pilot plant in Copiapó, Chile over an operating period of 384 hours with 14 cycles completed\n· This completes the first stage of production from the DLE pilot plant\n· Results show the DLE adsorbent achieved a lithium recovery rate of approximately 95% from the brine, with total recovery (adsorption plus desorption) achieving approximately 88%\n· Impurity rejection rates were very high producing a low impurity eluate conducive to the downstream conversion process.\n· The concentrated eluate is being shipped in four batches to the facilities of Conductive Energy in Chicago, USA, for conversion into battery grade lithium carbonate\n\n\n\n\nShipment\n\n\nEluate Volume\n\n\nEluate Li Grade\n\n\nLCE (kg)\n\n\nShipment Status\n\n\n\n\n1\n\n\n24m3\n\n\n2008 mg/L\n\n\n257\n\n\nArrived process facility\n\n\n\n\n2\n\n\n24m3\n\n\n2360 mg/L\n\n\n301\n\n\nIn Shipment\n\n\n\n\n3\n\n\n24m3\n\n\n2325 mg/L\n\n\n297\n\n\nIn shipment\n\n\n\n\n4\n\n\n17.5m3\n\n\n2464 mg/L\n\n\n230\n\n\nAt departure port\n\n\n\n\nTargeted\n\n\n90m3\n\n\n2000 mg/L\n\n\n1022\n\n\n\n\n\n\n\nTotal Achieved\n\n\n88m3\n\n\n2289 mg/L\n\n\n1085\n\n\n\n\n\n\n\nTable 1: Status of concentrated eluate from pilot plant first stage production\n· Conductive Energy completed test-work on a 200L sample of concentrated eluate shipped in May 2024 to optimise the downstream process before receiving the larger volume shipments\n· The conversion test-work produced multiple sampl...
