The project is most sensitive to the price of electrolytic manganese followed by operating costs and capital costs.
As shown in the Report, the total amount of EMM produced over the life of the mine is estimated to be 994,499 tonnes (about 2.19 billion pounds). The average unit production cost of the EMM, after credits from by-product and on-site waste steam power generation, is shown below. The plan incorporates a low waste strip ratio (2.20:1) and higher grade (3.13% Mn) in the first 6 years of operation; followed by the second phase of mining ending in year 10 that has an average grade of 2.68% MN and a waste strip ratio of 2.17:1.

The initial capital cost is estimated at $477 million, and would be mostly spent over the 2 year engineering, procurement and construction period. The sustaining capital over the contemplated mine life is estimated at approximately $60 million. Allowances for end of mine life expenditures for waste re-handling, site reclamation, and plant salvage have been made totaling about $47 million.
The Report is based on geological work and drilling performed by the Company under the supervision of N. Tribe & Associates Ltd. Tetra Tech developed a geological block model for that portion of the deposit located along the northeast flank of Manganese Mesa that is most amenable to surface mining. The geological block model contains Indicated and Inferred resources estimated as follows:
---------------------------------------------------------------------------
Cut-off Tonnes Grade
Category (%Mn) (Millions) (% Mn)
---------------------------------------------------------------------------
Indicated Resource 0.5 65.7 2.2
---------------------------------------------------------------------------
Inferred Resource 0.5 20.4 2.5
---------------------------------------------------------------------------
From this starting point, a mining plan was developed using waste haul back open pit mining techniques. The open pit has been designed to achieve a mine life of 21 years, and is estimated to contain a Probable Reserve of 45 million tonnes grading 2.46 % Mn. The average stripping ratio (waste tonnes: ore tonnes) is estimated at 2.46:1. A unique feature of the design is that most of the waste rock is disposed of within the mined out areas of the open pit as they become safely available; which minimizes land surface disturbance and hauling costs, while facilitating progressive site reclamation.
The mine production schedule is designed to produce about 50,000 tonnes of electrolytic manganese metal (EMM) annually from a processing plant capable of treating 7,000 tonnes of feed per day. Hydraulic front shovel and rubber-tire front end loading units are matched with 150 tonne mechanical drive haul trucks to provide the back bone of the mining fleet. Drilling, ancillary and support equipment are allocated to meet the requirements of the production schedule.
Cleaner energy-efficient hydrometallurgical process
The EMM production process uses a reductive leach hydrometallurgical process developed and tested by Kemetco Research Inc. (patent pending by American Manganese Inc.), and manganese metal specific electro-winning technology. The resulting tailing would be co-disposed with the waste rock within the mined out areas of the open pit mine.
The Report is based on the results from continuous pilot plant testing program performed by Kemetco Research Inc., and its specialist subcontractors, during the last half of 2011 and the first quarter of 2012. Using its experience and a proprietary in-house process simulation computer program, Tetra Tech scaled-up the test data to the desired commercial size plant for design and cost estimating purposes.
Re-use of process water
Surface disturbances for the contemplated mining and processing operations are limited to a single drainage. Surface water is diverted around the disturbed areas; while process water and water accumulated within disturbed areas is collected, re-used, and not allowed to enter the undisturbed watershed.
From the mine design, process design and layout, and site restoration philosophy Tetra Tech has prepared capital and operating cost estimates for the planned development. These estimates were prepared in accordance with good engineering practice and accurately reflect the level of preliminary feasibility study.
CPM Group prepared a market study (follow this link to review CPM Summary: http://amydata.com/data/reports/Electrolytic_Manganese_Metal_Outlook_2011_ExecutiveSummary.pdf), including an EMM price forecast which is being used in the Report. Quoting from the CPM Group study: "Over the next 10 years real electrolytic manganese metal prices are forecast to average $1.92 per pound, reaching an annual high of $2.30 in 2021." The study also provides up-side and down-side EMM price scenarios which have also been used in the Report.
"We believe that we have received excellent work from all of our consultants. The project design capitalizes on a much better understanding of the character, controls and distribution of the mineralization, maximizing the overall utilization of the manganese resource within the contemplated mining area," says Mr. Larry Reaugh. "The combined work produced solid representation of the commercial opportunity offered by developing the manganese deposits at Artillery Peak in the current rapidly escalating capital and operating cost environment. The Artillery Peak EMM production cost is estimated to be much lower than published Chinese production costs. Under the CPM Group pricing scenarios used for the Report, the Artillery Peak Manganese Project is economically attractive. The technical aspects for mining and processing for the contemplated project have been thoroughly addressed and significantly de-risked. What risk remains is mostly attributable to the economic climate, or metal market, which is typical for any natural resource opportunity. This risk would affect all competitive manganese producers and developers equally. As such, American Manganese strives to become a low cost producer with a sustainable economic advantage over the competition."
"Further metallurgical testing and engineering work necessary to advance the Project to the feasibility level will focus on process optimization opportunities that could significantly reduce the capital and operating costs, particularly in the liquid-solid separation, sodium sulfate production process areas, more efficient use of thermal steam from the sulfur burner, and construction materials for tanks and equipment. These opportunities were identified during the course of the Preliminary Feasibility Study and provide a clear path for the next phase of work. We will also explore and incorporate ideas and technologies that could lead to the production of products suitable for use in the emerging rechargeable electric battery market."
"I am pleased with the overall results and look forward to advancing the Project to the feasibility level, leading eventually to a positive project development decision," concludes Mr. Reaugh.
Investors and media are invited to join American Manganese in a press conference on Friday, May 18, 2012 at 10:00am PST to discuss the preliminary feasibility study.

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.
The current world price for electrolytic manganese metal is about $1.46 per pound, while the U.S. price is about $1.66 per pound.
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 from its Arizona Manganese Project.
