Bulk Tonnage Targets Indicated from 2011-2012 Field Work
Added November 20th, 2012 – Vancouver, British Columbia
Larry W. Reaugh, Chief Executive Officer of American Manganese Inc. (“American Manganese” or the “Company”), (TSX.V: AMY; Pink Sheets: AMYZF; Frankfurt: 2AM), is pleased to announce results from the Company’s 2011-2012 exploration and prospecting program entailing 8 square kilometers within their 9,957 sq. km Rocher Deboule IOCG property located 8 km south of Hazelton, BC. The program entailed 22 km of ground magnetometer survey, 841 soil samples, 455 rock samples and 68 silt samples. The fieldwork carried out in 2012 focused on 3 areas of Cu-Ag-Au bearing mineralization as described.
Geological fieldwork returned encouraging Cu-Ag-Au geochemical values at the Rocher Deboule project upper silvertip CK basin stockwork, lower silvertip CK No 2 & 4 veins and a new Iron Oxide Copper Gold (“IOCG”) target south of the historic Victoria vein mine. Highlights of the program are outlined below:
1. UPPER SILVERTIP CREEK BASIN STOCKWORK: This area is approximately 0.5-1.5 km northeast of the historic Rocher Deboule mine site. In 2008, Dighem airborne total field magnetometer geophysical surveys identified a strong positive anomaly (60,000-62,000 nT, approximately 3,000-5,000 nT above average) over an area of about 0.5 X 1.0 km. Follow up rock sampling in 2011 by Ethier Exploration, Hazelton, BC generated the following result highlights:
2011 ROCK CHIP SAMPLE GEOCHEMICAL ANALYSIS
|Sample No||Cu %||Ag g/t||Au g/t||Description|
|11DE853||0.34||9.4||7.0||Clay altered fractures contain chalcopyrite-magnetite|
|11DE834||19.0||11.0||27.0||Grab sample, semi-massive chalcopyrite|
|11DE854||5.0||4.6||5.0||Quartz veining, strong alteration & bleaching|
|11DE870||0.03||10.7||>100.0||Rock chip sample across 45 cm|
|11DE838||>1.0||32.0||1.3||9 quartz veins in 2 meter rock chip sample|
|11DE860-863||33.0||3.2||25.0||Average of 4 rock chip samples|
|11DE866||>1.0||41.0||3.7||Grab sample, chalcopyrite|
|11DE840||>1.0||14.0||6.0||Rock chip sample across 25 cm|
|11DE839||7.0||8.2||0.77||Quartz veinlets across 15 cm|

2. LOWER SILVERTIP CREEK QUARTZ VEIN ZONE: Additional rock and soil sampling was carried out in the historic Rocher Deboule mine area located on the lower elevation portion of Silvertip Creek. Over an area of about 0.5 X 0.7 km, the following rock & soil samples taken in 2012 by Andris Kikauka (geologist) generated the following results:

3. Additional prospecting by Ethier Exploration was carried out approximately 2 km west of the Upper Silvertip Basin Stockwork Zone, and about 0.7 km south of the historic Victoria mine, indentifing a bulk tonnage target near the contact of the Late Cretaceous Rocher Deboule porphyritic granodiorite
stock with older hornfels volcanic and sedimentary rocks. This contact zone is considered highly prospective for IOCG type mineralization, which is supported by the fact that the Rocher Deboule occurrence ranks in the 95th percentile in combined Cu-Au-Fe-La in RGS province wide geochemical survey (source: Ministry of Energy, Mines & Petroleum).
The Company carried out most of 2011-12 fieldwork in a 3 X 2 km area surrounding the historic Rocher Deboule Cu-Ag-Au mine which from 1914-1954, mined 123,395 tonnes, producing 2,840,966 kgs Cu, 2,653,086 grams Ag, 157,226 grams Au, and 34,692 kgs W (source: Minfile database). Historic work in 1988 by Southern Gold Res Ltd on the Rocher Deboule No 2 Vein resulted in a resource estimate of 54,000 tonnes grading 2.7% Cu, 207.4 g/t Ag, & 3.5 g/t Au (note: this is a historic estimate that is not current with NI 43-101 standards, and is NOT TO BE RELIED UPON).
