American Manganese Inc.: American Manganese Prepares Recycled Lithium-Ion Battery NMC Cathode Waste for Cathode Precursor Production Company Begins Sourcing Equipment for RecycLiCo Demonstration Plant SURREY, BC / ACCESSWIRE / April 29, 2021 / American Manganese Inc. (TSXV:AMY)(OTCQB:AMYZF)(FSE:2AM) (" AMY" or the " Company") and its independent R&D contractor Kemetco Research Inc. ( "Kemetco") are pleased to report that the pregnant leach solution (PLS) produced during the leaching stages of NMC (lithium-nickel-manganese-cobalt oxide) cathode waste, using AMY's patented lithium-ion battery cathode recycling process ( RecycLiCo), has been prepared for cathode precursor production testing. The NMC testing follows the earlier production of cathode precursor material from recycled NCA (lithium-nickel-cobalt-aluminum oxide) cathode waste, as reported in the Company's March 31, 2021 press release. AMY's goal is to achieve the technical targets set by traditional lithium-ion battery cathode precursor manufacturers and to demonstrate the potential to recycle NMC or NCA cathode waste into high-value cathode precursor products for direct integration in the re-manufacturing of new lithium-ion batteries.
