The patent application describes key details in which manganese can be recovered from a low grade resource with the following key advantages:

--  Low energy requirement.
--  Low water use.
--  Robust process with a unique assembly of commercially available
    equipment.
--  Suitable for production of high purity electrolytic manganese metal
    (EMM) without the use of selenium, a toxic concentration found in
    traditional Chinese EMM production.
--  Suitable for production of high purity electrolytic and chemical
    manganese dioxide for use in high tech lithium ion batteries.

With the trend of increasing metal prices, decreasing resource grades and environmental regulations becoming stricter, ownership of this intellectual property creates significant opportunity for American Manganese on a world scale.

About Manganese

China controls electrolytic manganese production supplying and producing 98% of the world's needs (3 billion pounds per year).

There is no substitute for manganese in steel (total manganese market greater than 33 billion pounds per year, fourth largest traded metal).

Manganese is the most critical metal at risk to supply and restriction in the United States as there is no U.S. production. EMM's greatest uses are the upgrading of specialty steel (74%), and the manufacture of aluminum alloys (12%) and electronics (2%).

Electrolytic manganese dioxide (EMD) for the battery industry is expected to be the fastest-growing segment of the manganese market. Ford Motors predicts production of electric vehicles will account for 25% of its entire vehicle line-up by 2020, and Hyundai has committed a lifetime guarantee to their electric vehicles that use lithium ion batteries with manganese spinel.

China has a 20% export duty on EMM and the U.S. has a 14% import duty.

The current world price for electrolytic manganese metal is about $1.30 per pound, while the U.S. price is about $1.63 per pound.

About American Manganese Inc.

American Manganese Inc. is a diversified specialty and critical metal Company focusing on potentially becoming the lowest cost producer of electrolytic manganese metal from its Arizona Manganese Project.
