American Manganese Inc. (“AMY” or the “Company”) is pleased to announce improvements to the Company’s manganese processing flowsheet following the recent research and development on the Wenden Stockpile reclamation and advanced material processing bench-scale project, funded by the U.S. Defense Logistics Agency (DLA).

The recent metallurgical bench-scale studies that focused on solid-liquid separation demonstrated that the Company’s original flowsheet can be optimized. These enhancements to the Company’s flowsheet would be expected to further improve process efficiencies and reduce capital costs of a potential future commercial operation.

“We continue to demonstrate our advanced manganese processing capabilities on low-grade manganese resources through our project with the DLA. Our work suggests that despite its low grade, the Wenden Stockpile may be a valuable manganese resource for the U.S., which is now 100% import-dependent for manganese in all forms,” commented Larry Reaugh, President and CEO of American Manganese. “It’s important that we maintain our methodical approach to enable an efficient and cost-effective flowsheet for treating Wenden Stockpile material to produce electrolytic manganese metal on a commercial scale.”

As of the project start date, American Manganese has collected 14 selective samples from the U.S. National Defense Stockpile in Wenden, Arizona and completed leach studies on the individual samples and a blended master composite. The Company achieved up to 99% extraction of manganese from the leach studies and determined optimal processing conditions. Additional bench-scale tests for the Wenden Stockpile reclamation and advanced material processing bench-scale project will include pregnant leach solution purification, tailings characterization, manganese carbonate precipitation, and electrolytic manganese metal testing. The project timeline is on schedule.
