American Manganese Inc.: Artillery Peak Manganese Project Review and Future Plans (ccnm)
VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 15, 2013) - Larry W. Reaugh, Chief Executive Officer of American Manganese Inc. ("American Manganese" or the "Company") (TSX VENTURE:AMY)(PINKSHEETS:AMYZF)(FRANKFURT:2AM), reports on American Manganese's 2011 and 2012 programs and managements plans relating to future development of the Artillery Peak Project.
Since the pre-feasibility study management has been studying ways to maximize their resources at Artillery Peak as follows:
- Address the opportunities to reduce capital expenses (capex) and operating expenses (opex) which include production of electrolytic manganese dioxide (EMD) or chemical manganese dioxide (CMD). Only 60% of manganese metal is used to produce an equivalent amount of EMD or CMD to EMM (100%) significantly reducing the footprint and positively affect the capex and opex. Production of CMD eliminates the requirement for electrolytic cells.
- The Company has identified areas to explore where the potential to increase the manganese grades exists such as:
- Wildcat drill hole AP-11-133 was drilled in the upper Shannon located 4 km west of manganese mesa and returned 7.62 meters grading 7.39% Mn.
- Wildcat diamond drill hole #ADH-25 was drilled 1.6 km south and east of Loves Mine and returned 24.39 meters of 4.34% Mn.
The Company will evaluate these targets which have the potential to host higher grades thereby possibly further reducing the overall foot print of the mill site and mining operations. Other areas on the property like the Maggie Canyon also host the potential for higher grades of manganese.
- Focus on the criticality of manganese to the U.S. Government and various potential end users.
- Continue the dialogue with potential off-takers that have shown an interest in the manganese metal and dioxide market.
- The elimination of the electrolytic cells by focussing on research and development of CMD could reduce the electrical requirements by up to 75-80%.
- Reducing the amount of production (25 - 40,000 Ts/year) of manganese dioxide product potentially reducing capex for mining and processing.
- American Manganese's cost of production is one of the lowest in the world.
- 10,607 meters (34,800 ft) of reverse circulation drilling in 84 holes (2011 program) was completed in the North Chapin, Lakes/MacGregor area resulting in the following Ni43-101 resource at a 1.0% Mn cut-off:
| || Resource (T) || Average |
| Contained |
Mn Metal (T)
| Indicated || 62,201,000 || 2.3% || 1,445,000 |
| Inferred || 20,033,000 || 2.5% || 506,000 |
Previous drilling and Ni-43-101 resource studies identified additional reported resources on the Maggie Mine/Shannon Mine/Loves/Hurley/Planche/South Chapin/Burro/Price and Priceless zones at a 0.9% Mn cut-off as follows:
| || Resource (T) || Average |
| Contained |
Mn Metal (T)
| Indicated || 145,575,196 || 2.98% || 4,279,000 |
| Inferred || 54,700,239 || 2.83% || 1,547,000 |
The Company has drilled 18,160 meters (59,565 ft) in 154 holes since 2008.
- On September 27, 2011 Kemetco completed the successful pilot plant operation on Artillery Peak materials. Initial results of the leach and solid/liquid separation pilot tests were excellent; for instance rates of extraction of 92.7% manganese recovered was achieved from coarse feed material (minus 6.35mm) in 2 hours. Initial expectation of the pilot plant was to process 3 to 5 kg of resource material per hour. In the continuous pilot plant run, the average processing rate was 20.8 kg per hour, which greatly exceeded expectation. Success of the pilot plant operation has removed a significant amount of technical risk from the flow sheet.
- On May 24, 2011, the Tucson, Arizona office of Tetra Tech was awarded the contract to provide environmental and consulting services to the Company on their Artillery Peak Project.
- On December 6, 2011, the Company received a detailed positive manganese market forecast study from CPM Group. Executive summary may be found on the website.
- March 14, 2012, the Company announced the publication of their advanced process patent application. The Company is addressing minor deficiencies received from the U.S. Patent Office and expects approval in the first quarter 2013.
- On August 27, 2012, the Company filed an Amended Pre-feasibility Study at the request of the British Columbia Securities Commission in which the base case was amended to the 3 years trailing average. The project was deemed to be uneconomic as a producer of electrolytic manganese metal (EMM). The production of electrolytic manganese dioxide (EMD) or chemical manganese dioxide (CMD) introduces a different set of dynamics to the project. All of the pilot plant testing, environmental studies and pre-feasibility may be incorporated into new studies for CMD or EMD.
- October 12, 2012, the Company's contractor, Kemetco Research Inc. successfully produced rechargeable lithium ion batteries from CMD produced from the Company's Artillery Peak pilot plant test. This is a major breakthrough. Future testing by Kemetco will focus on a high purity product for the battery industry.
About American Manganese Inc.
American Manganese Inc. is a diversified specialty and critical metal Company focusing on potentially becoming a producer of high purity EMD and CMD for the battery industry.
