Mr. Reaugh states that: “the process which has been designed to be energy and water efficient and address all processing concerns in regard to the environment will not substantially affect the economics of the project as envisioned in the previously announced NI 43-101 “Preliminary Economic Assessment”.”

The process is described in the report “The Recovery of Manganese from Low Grade Resources:  Bench Scale Test Program Completed” prepared for the Company by Kemetco Research Inc. (“Kemetco”) of Richmond, British Columbia, dated July 1, 2010.  The report confirms that the process can extract manganese at greater than 90% efficiency while minimizing water and energy use, and the potential environmental foot print.  The conceptual process flow sheet developed from this testing program is based on a unique application of commercially available process equipment.  In addition to production of electrolytic manganese metal a saleable anhydrous sodium sulphate by-product will also be produced.

Leaching studies performed on typical manganese samples of large particle size (greater than 9.5 mm) with SO₂ leachant in stirred tanks indicates that the material is readily leachable.  The material is friable and large particles break down easily during stirred tank leaching. 

SO₂ leachant is produced on-site by burning elemental sulphur with 20% excess air.  At the contemplated feed processing rate of 3500 tonnes/day, heat exchanging the exhaust gases from the sulphur burner will produce an estimated 20 tonnes per hour of steam at 400^oC and 45 bar pressure.  In a condensing turbine this steam can produce 5 MW of continuous electrical power; sufficient to operate the extraction and by-product production processes.

The pregnant leach solution (“PLS”) is purified in two stages prior to precipitating the metal as manganese carbonate.  Re-dissolving the manganese carbonate with recycled electrolyte produces a solution that is conducive to producing high grade manganese metal by electro-winning.

Water recovery from the manganese barren process solution can be achieved with high energy efficiency because of the unique solubility characteristics of the sodium sulphate remaining in solution. Sodium sulphate can be crystallized by cooling the solution to 0°C, and the water can be recovered via commercially available nano-filtration technology.  This approach is significantly more energy efficient than standard evaporation as it avoids latent heat required for vaporizing the water.

Solid tailings with minimum water content are produced by filtration of the final CCD underflow material minimizing water requirements for the overall process.  The solid tailings produced from test work were shown to be benign by the Toxicity Characteristic Leaching Procedure (“TCLP”), and can be returned to mined-out areas of the open pit facilitating immediate progressive reclamation of disturbed areas.

About Manganese

China controls electrolytic manganese production (EMM) supplying and producing 97.44% of the world’s needs (2.6 billion pounds per year).

There is no substitute for manganese in steel (total manganese market greater than 30 billion pounds per year, fourth largest traded metal).

Manganese is the most critical metal at risk to supply and restriction in the United States as there is no US production. EMM’s greatest uses are the upgrading of specialty steel (47%), and the manufacture of aluminum alloys (32%) and electronics (14%).

China has a 20% export duty on EMM and the US has a 14% import duty, world price is $1.28/lb. and US price is $1.53/lb.

Manganese resources are declining in China.

The 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.

“The Artillery Peak manganese mineralization is located within basin filling alluvial fan/playa deposit which typically exhibit large thickness and lateral continuity” says Mr. Reaugh.  He goes on to say:  “According to the US Geological Survey, Bulletin 961, the bedded deposits of the Chapin Wash formation have the potential for hosting immense tonnage of prospective manganese mineralization.  The success of this drilling program demonstrates that character and continuity.”

4526.3 meters (14,850 ft) has been drilled in 53 holes, and the significant results for holes 49-53 are shown in the following table.  The drilling program has now been completed and data compilation review and the preparation of an up-to-date NI 43-101 compliant resource estimate are underway.

See the drill plan map at:  

Mr. Reaugh states:  “I am very gratified with the results to date as it lays the ground work for the next stage of process development:  proof of concept testing on a continuous basis of our innovative extraction technology.  Furthermore, I would like to say that American Manganese is very grateful for the financial support given by the National Research Council of Canada Industrial Research Assistance Program.”

In May 2009, the Company commissioned Kemetco to develop a robust energy efficient hydrometallurgical process which would yield high purity manganese metal and/or manganese dioxide while minimizing potential environmental impacts.  The work integrates and builds upon the extensive research carried out most notably by the United States Bureau of Mines intermittently from the 1940’s through the 1980’s and proprietary third party research conducted by other mining companies.

The report confirms that American Manganese’s proprietary process can extract manganese at greater than 90% efficiency while minimizing water use and potential environmental impacts.  The conceptual process flow sheet developed during this test program is based on a unique application of commercially available process equipment so that the process is deemed to be robust and energy efficient.  In addition to the production of electrolytic manganese metal, a saleable anhydrous sulphate by-product will also be produced. 

Treatment of typical manganese samples containing between 4% and 7% Mn by weight (primarily in the form of pyrolusite, psilomelane and wad), is carried out in a hydrometallurgical process whereby four-valent Mn is reduced and leached by sulphur dioxide (SO₂) dissolved in water.  The hydrometallurgical processing of friable lower-grade material avoids intensive crushing and grinding, as well as the undesirable high temperature reduction roasting that is conventionally used in processing hard high-grade material.  Roasting at temperatures typically between 800°C and 1000°C is energy intensive and would not be economical for lower-grade material.

Leaching studies performed on typical manganese samples of large particle size (greater than 9.5 mm) with dilute SO₂ in stirred tanks indicates that the material is readily leachable.  The material is friable and large particles break down easily during stirred tank leaching.  SO₂ leachant is produced on-site by burning elemental sulphur with 20% excess air.  At a feed processing rate of 3500 tonnes/day, heat exchanging the exhaust gases from the sulphur burner will produce an estimated 20 tonnes per hour of steam at 400^oC and 45 bar pressure.  In a condensing turbine, this steam can produce 5 MW of continuous electrical power. 

The pregnant leach solution (PLS) is purified in 2 stages prior to separating the manganese by precipitation.  Dissolving the precipitate with recycled electrolyte produces a Mn-containing solution that is conducive to producing high-grade Mn metal by electro-winning.

Solid tailings with minimum water content are produced by filtration of the final counter current decantation underflow material, minimizing water requirements for the overall process.  The solid tailings produced from test work were shown to be benign by the Toxicity Characteristic Leaching Procedure, and can be returned to mined-out areas of an open pit facilitating immediate progressive reclamation of disturbed areas.

Based on the successful test work, conceptual flow sheets have been developed which include applications of novel, proprietary, innovative technology to minimize process operating costs through low water use, low overall energy use and economic destruction of unwanted by-products.  Accordingly, American Manganese Inc. has requested Kemetco to file an application for patent protection.
