Larry W. Reaugh, President and Cheif Executive Officer of American Manganese Inc., (TSX.V: AMY; Pink Sheets: AMYZF) (“American Manganese” or the “Company”) is pleased to report and review the Artillery Peak Arizona Manganese Project over the past year as follows:

The Company had initially acquired by option 90 unpatented mineral claims hosting several known manganese occurrences in 2007.  The company has subsequently increased its land holdings to 116 patented and 254 unpatented claims covering an area of approximately 3200 hectares (7,900 acres).  In early 2008 a 17 hole diamond drill program entailing 3,050 meters (9,995 feet) was completed resulting in an initial NI 43-101 compliant resource of:

See press release dated November 24, 2009 for description of the low cost processing method for producing electrolytic manganese.

November 5, 2009 (Lonnie Niobium, BC Property)

The Company completed 5 diamond drill holes entailing 475 meters on the new Lonnie North Carbonatite.  Results contained no significant assays.  The known occurrences of niobium and rare earths remain untested.  A follow up drilling program to test the original Lonnie lense is planned for this year.

March 18, 2010

The Company commenced a reverse circulation drill program entailing 15,885 meters (52,000 ft) of drilling in 191 holes to increase the integrity of the current resources from indicated and inferred to measured and indicated, and increase the size of the known NI 43-101 resources.  To date 12 holes have been completed, with 5 holes submitted for assay on March 25, 2010.

On going metallurgical testing by Kemetco Research labs to streamline the process as well as lay the foundation for developing a process stream is ongoing.

About Manganese

  • China controls electrolytic manganese (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.  There is 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 $1.33/lb and US price is $1.68/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.
