(AMY) is pleased to announce that the United States Patent and Trade Mark Office has issued patent No. 10,246,343 for the Company's lithium-ion battery cathode material recycling technology. The granting of the patent is a significant milestone as it now provides legal protection of the Company's flagship technology.Mr. Norm Chow, inventor of AMY's technology states, \"the granting of the U.S. Patent confirms that our research is both novel and inventive. It is extremely exciting to have the opportunity to potentially contribute to the sustainability of future global electrification, which I believe will be valuable to the long-term health of our planet.\"\"When developing this technology, we looked at current methods of recycling waste lithium-ion batteries and discovered high heat smelting to be the primary method,\" Mr. Chow continued. \"Because active cathode materials are oxides, the first thing that came to mind was the comparison to steelmaking. Since smelting iron ore in steelmaking generates a considerable amount of CO2, we were compelled to develop an alternative process with a sustainable focus. During research development, we applied Near Net Shape manufacturing principles with the goal of efficiently recycling cathode material and generating products as close to the final form as possible, with minimum processing steps.\"Instead of relying on acquiring and developing mines in high risk jurisdictions to supply the growing demand for battery materials, AMY aims to have its patented urban mining technology provide a sustainable and geopolitically friendly supply of battery materials. Conventional Mining American Manganese Patented Technology Environmental permitting Mining various ores from geopolitically uncertain parts of the world Tailings management and disposal Smelting and refining (such as with solvent extraction and electrowinning) Re-dissolution of the metals with acid Crystallization to make metal sulfates Extraction of all cathode metals from lithium-ion batteries Precipitation of base metal oxides and lithium carbonate Ready for battery manufacturers to utilize base metal oxi...
