[{"type":"text","content":" VANCOUVER, British Columbia, May 07, 2020 (GLOBE NEWSWIRE) -- American Lithium Corp. (TSXV: LI) (OTCQB: LIACF) (Frankfurt: 5LA1) (“American Lithium” or the “Company”) a leading lithium exploration and development operator is pleased to report highly encouraging results from ongoing metallurgical testing regarding recovery of lithium from composite samples of reverse circulation drill cuttings from the Company's wholly owned TLC Lithium Claystone discovery near Tonopah, Nevada. Testing conducted by McClelland Laboratories of Sparks, Nevada, demonstrates that lithium recoveries exceeding 90% are achieved in 10 minutes with sulfuric acid leaching. Drill cuttings were subjected to several extraction methods including: agitated leach, acid curing and counter-current agitated leach. In combination with the process evaluation, leach solution temperature was investigated. In general, TLC lithium claystone is consistently highly leachable throughout the project with leach times comparing very favourably with other claystone projects. Highlights: Greater than 90% lithium recoveries achieved by sulfuric acid leaching of TLC mineralized samples; At a moderate 60°C leaching temperature, lithium extraction from mineralized material was complete in 30 minutes, with approximately 90% extracted within 10 minutes; Lithium extractions approaching 90% were also demonstrated with an ambient temperature acid curing process; A counter-current leaching test demonstrated that mineralized material can be used to neutralize the sulfuric acid leaching solution, removing iron and aluminum (impurities) from solution and minimizing the requirement for alkaline reagents. Since mid-2018, American Lithium has advanced TLC through reverse circulation, rotary and core drilling to establish high-grade lithium over an area of several square miles. In addition to the drilling and subsequent assay analysis, metallurgical and process testing has been completed. Stantec Consulting Ltd. has been engaged to complete a maiden resource lithium resource estimate for the TLC project (see Company news release dated April 15, 2020). The Company expects to release the results of this work and a technical report thereon, shortly. This early metallurgical work, coupled with information and recommendations from Stantec's work, will form the basis of continued development at TLC. M...
