American Manganese reports Large Thickness of Manganese Mineralization

Added June 23rd, 2010 – Vancouver, British Columbia


Larry W. Reaugh, President and Chief Executive Officer of American Manganese Inc., (TSX.V: AMY; Pink Sheets: AMYZF) (“American Manganese” or the “Company”) is pleased to report the Company has received results for drill hole numbers 38 – 43 which are located on the North Maggie zone of the Manganese Mesa, from its on going Artillery Peak drilling program.  Results for drill holes 1 through 37 have been announced previously. 

The mineralization at Artillery Peak Mohave County, Arizona takes the form of paleo-alluvial fans spreading out down slope from a number of source vents.

Up to and including hole number AP10-43, 3,629 meters (11,905 ft) has been drilled in 43 holes and the significant results from holes 38 – 43 are shown in the following table.

*Delineates northern fringe of the Maggie Zone.

Assays were performed by ALS Chemex in Sparks, Nevada.  Further results will be reported as they are received.

Mr. Reaugh states:  “These results demonstrate the character and continuity of the mineralized horizon; both of which tend to favor low cost open pit bulk mining development scenarios.”

About Manganese

  • China controls electrolytic manganese production (EMM) supplying and producing 97.44% of the worlds needs (2.6 billion pounds per year).
  • There is no substitution for manganese in steel (total manganese market greater than 30 billion pounds per year, fourth largest traded metal).
  • The most critical metal at risk to supply and restriction in the United States.  No US production. 
  • EMM’s greatest uses are upgrading specialty steel 47%, manufacture of aluminum 32% and electronics 14%.
  • China has a 20% export duty on EMM and the US has a 14% import duty, world price is $1.22/lb. and US price is $1.55/lb.
  • Manganese resources are declining in China.
  • 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.
