About Manganese

China controls electrolytic manganese production (EMM) supplying and producing 97.44% of the world's needs (2.6 billion pounds per year).

There is no substitute for manganese in steel (total manganese market greater than 30 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 US production. EMM's greatest uses are the upgrading of specialty steel (47%), and the manufacture of aluminum alloys (32%) and electronics (14%).

China has a 20% export duty on EMM and the US has a 14% import duty; (US Price $1.81/lb) the current world price for Electrolytic Manganese Metal is about $1.52/lb. Manganese resources are declining in China especially carbonate ores for production of EMM, forcing Chinese companies to seek production offshore.

The overall manganese market grew at 8% per year to 30 billion pounds up to 2008. EMM market grew at 26% per year from 2003 - 2008 to 2.6 billion pounds per year.

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 from its Arizona Manganese Project.
