The newest check work quickly upgraded samples of TLC mineralization from 1,098 ppm Li to 1,671 ppm Li by retaining as a lot as 88% of the lithium in 60% of the unique mass — representing a grade improve of 52% (or an upgrading issue of roughly 1.5). The method is estimated to take lower than 45 minutes in an industrial-scale operation.
Testing will proceed to additional optimize the upgrading course of together with using higher-grade feed from deliberate drilling and bulk sampling at TLC, the corporate mentioned.
Processing materials with considerably greater lithium concentrations ought to scale back prices by decrease reagent consumption and diminished throughput, together with the potential to scale back back-end processing plant necessities, it added.
“By processing higher-grade lithium mineralization, a smaller plant footprint is feasible, and processing turns into extra environment friendly with the power to attenuate reagents and enhance recoveries,” mentioned Dr. Laurence Stefan, COO of American Lithium in a press launch.
Final month, the corporate reported one of the best lithium extraction outcomes to this point on the TLC claystones, reaching a 97.4% extraction price utilizing heat sulfuric acid leach.
Shares of American Lithium gained 6.3% by midday EDT on the TSXV following the newest testing outcomes. The corporate has a market capitalization of C$474.8 million.
