Rock and Soil from Rocher Deboule Project Vent & Victoria Zones Feature Au-Ag-Co-Cu-Mo-Fe-REE Mineralization Similar to IOCG ‘Iron-Oxide Copper-Gold’ Deposits

American Manganese Inc. (“AMY” or the “Company”) is pleased to report work was completed on the Rocher Deboule property located 5-8 kilometers southwest of Hazelton, BC. The Rocher Deboule deposit has had historic production of 36,457 tonnes containing 2,167,780 grams silver, 133,676 grams gold and 2,557,433 kilograms of copper between 1915 and 1929; the adjacent Highland Boy produced 68 tonnes containing 1,089 grams silver, 124 grams gold and 4,760 kilograms of copper, and the nearby Victoria produced 51 tonnes, containing 7,341 grams gold, 7,710 kilograms of arsenic and 785 kilograms of cobalt between 1926 and 1940. These mineral deposits are associated with the Late Cretaceous Bulkley Plutonic Suite, and the Rocher Deboule feldspar porphyry stock.

Recent fieldwork involving rock and soil sampling of the western portion of the claims has revealed potential for “Iron Oxide Copper Gold” deposit types. The Victoria No 1-3 Veins are intrusive hosted, and rock samples contain high grade Co-Au values associated with Mo-As. The Victoria No 3 Vein trends west towards Upper Cretaceous Kasalka Fm volcanic-hosted garnet-sericite-illite-quartz-calcite-chlorite-actinolite alteration. The Vent Zone alteration occupies a 250 X 350-meter area where widespread Au-Co-Cu-Mo-Fe-REE bearing mineralization is present. The Vent Zone also displays coincident 2017 Actlab SGH geochemical survey (6.0 out of 6.0 rating) redox cell, combined with 2011, well defined, Fugro magnetometer airborne geophysical anomaly. The Vent zone is interpreted as favourable geology for IOCG (iron-oxide copper-gold) type mineralization and is considered a high priority drill target.

The Cap showings are hosted in andesitic flows/tuffs (porphyritic) of Upper Cretaceous Kasalka Group (Brian Boru Formation). The Cap showings consist of multiple, parallel and sub-parallel zones of fault-fracture controlled quartz-carbonate-sulphide veins and breccia. A sample taken from multi-vein fracture zone returned assay value of 1,845 g/t Ag associated with chalcopyrite and pyrite accompanied by widespread quartz-sericite-illite-chlorite-kaolinite-calcite alteration.

The Management plans to advance exploration and development work on the Vent, Cap and Victoria Zones. In order to intersect depth extensions of surface mineralization outlined by anomalous Au-Ag-Co-Cu-Mo in soil and rock chip samples, approximately 1,400 meters of core drilling has been proposed.
