Larry W. Reaugh, President and Chief Executive Officer of American Manganese
Inc. ("American Manganese" or the "Company") (TSX
VENTURE:AMY)(PINKSHEETS:AMYZF)(FRANKFURT:2AM), is pleased to announce the
Company's progress to date on the research in expanding the Company's patent
pending hydrometallurgical manganese recovery process to produce improved
manganese dioxide product for use in rechargeable lithium ion batteries.
Recent laboratory tests have produced Electrolytic Manganese Dioxide (EMD) and
Chemical Manganese Dioxide (CMD) products of high quality. These products were
produced from leaching the Artillery Peak, Arizona mineralized samples and their
subsequent purification and elecrowinning to produce EMD or chemical oxidation
to produce CMD.
Samples of the EMD and CMD were analyzed by inductively coupled plasma
spectroscopy (ICP) for cation impurities. A summary of the cation impurities for
American Manganese EMD and CMD samples and specification of Tosoh and Tronox EMD
products are provided below.

While cation impurities are important, more critically, the American
Manganese process avoids steps (such as grinding the resource material in
the cases of EMD and CMD, or grinding of the final products which is avoided
in CMD production) that are known to introduce metallic impurities into the
final products.
American Manganese's research is focusing on capitalizing on its patent pending
hydrometallurgical process developed by Kemetco Research to significantly reduce
or eliminate metallic impurities in manganese dioxide for use in rechargeable
lithium ion batteries.
Metallic impurities, not to be confused with metal oxide or salt impurities, in
the part per billion level are known to cause an unacceptable number of
batteries to experience thermal run-away in rechargeable lithium ion batteries,
leading to explosions and fires in some cases. The tolerances for these
impurities are so low that there are no current analytical methods to measure.
As such, all lithium ion battery manufacturers test every battery manufactured
for a few weeks to reduce (but not eliminate) the occurrence of thermal run-away
of production batteries prior to sale.
Mr. Larry Reaugh says, "These initial results are very encouraging as the
hydrometallurgical process developed by Kemetco provides a significant
opportunity for the production of a high value product for use in rechargeable
lithium ion batteries and represents another market with very high growth
potential. While the Company's primary focus is electrolytic manganese metal
(EMM), we are going to aggressively pursue the on-going research program that is
required to fully develop this extremely attractive potential opportunity. We
have forwarded these results to interested potential off-takers and/or strategic
partners."
About Kemetco Research Inc.
Kemetco Research is a privately owned contract Research and Development Company
specializing in extractive metallurgy, chemical processing and specialty
chemical analysis. Kemetco was formed after the acquisition of the Industrial
Process Division of BC Research. BC Research had been in operation for over 60
years as an R&D contractor in British Columbia, Canada.
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 a critical metal at risk for supply disruptions 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%), electronics
(2%), and other applications (12%).
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 hybrid electric vehicles will account for 25% of its entire
vehicle line-up by 2020, and Hyundai has committed a lifetime guarantee to their
hybrid 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.
About American Manganese Inc.
American Manganese Inc. is a diversified specialty and critical metal Company
focusing on potentially becoming a producer of electrolytic manganese metal,
electrolytic manganese dioxide and chemical manganese dioxide from its Arizona
Manganese Project.
