American Manganese Inc., (formerly: Rocher Deboule Minerals Corp.) (TSX.V: AMY; Pink Sheets: AMYZF) (“American Manganese” or the “Company”) reports that Company’s upcoming drill program on its Artillery Peaks Manganese Project, located south of Kingman Arizona is getting underway and aggressively plans to move the Project forward through the exploration/evaluation process to a successful production decision as follows:

1. Drill permits have been received from the Bureau of Land Management.

2. Drilling contract has been awarded to Brown Drilling of Kingman, Arizona. The first reverse circulation drill rig is scheduled to begin drilling within the week, and a second drill scheduled to arrive in 10 days thereafter.

3. Michael MacLeod, P.Eng has joined the Company as its Chief Operating Officer and will be responsible for guiding the project through the exploration, evaluation, development, and regulatory approvals processes. His duties include, but are not limited to:

• Identifying and engaging engineering and other professional contractors for performing the engineering, socio-economic, and environmental work necessary to prepare preliminary and final economic feasibility studies, and satisfy the local, state and federal regulatory authorities;

• Preparation of the Mining Plan to be filed with the State of Arizona;

• Co-ordinate the metallurgical testing and process development studies from bench scale through pilot plant scale operations;

• Identifying and hiring the personnel as required for advancing the project from the exploration stage through development and construction and into the subsequent operation stage.

The Artillery Peak manganese project has an established NI-43-101 resource as follows:

[table id=4 /]

A compliant NI-43-101 Preliminary Economic Assessment, prepared in August 2009, indicated that a mine and facilities processing a nominal 3500 tonnes per day over its 17 year life could potentially generate attractive economic returns (on a pre-tax basis using a selling price of US$1.10/lb for electrolytic manganese), along with a low operating cost of US$0.44/lb and a fast payback of 1.73 years, at an estimated capital cost of US$90 million.

The objectives of the drilling program include adding new resources to the existing mineral inventory and to increase the quality and confidence of the mineralization and tonnage estimates so that the mineral resources can be up-graded from the Inferred category to the Indicated or Measured categories. This will enable the Company to evaluate the commercial potential of increasing the contemplated processing rate to 5,000, 10,000, or 15,000 tonnes per day.

Lonnie/Virgil Niobium, British Columbia Project

The Company drilled 5 holes at two locations on a previously untested carbonatite showing located approximately 1 kilometer north and west of the known Lonnie carbonatite (where previous exploration assayed 0.20% Nb2O5 over a strike length of 500 meters). No significant value in niobium or rare earths was obtained.
