American Manganese Inc. reported Vent Zone IP Geophysics Identifies High Chargeability and coincident and Significant Rare Earth Values on Rocher Deboule Cu-Au-Ag Project: The Vent Zone alteration consists of chlorite-quartz-carbonate-garnet-clay hosted in andesitic flows/tuffs (porphyritic) of Upper Cretaceous Kasalka Group Brian Boru Formation. SGH (spatiotemporal geochemical hydrocarbon) surveys carried out in 2017 resulted in redox cell (6.0 out of 6.0 rating), and copper-gold anomalous zones (5.0 out of 6.0 rating) that coincide with the redox cell anomaly. In 2021, pole-dipole array IP Geophysics on "Vent Zone" target identified elevated chargeability (>30 mV/V), which correlates with the redox-cell soil hydrocarbon anomaly.

Widespread, disseminated sulphides (mostly fine grain pyrite) are present in the portions of the Vent Zone. IP survey high chargeability and coincident low resistivity on west portion of grid area are interpreted extent of Vent Zone. In the central part of the IP survey area, relatively strong chargeability and low resistivity increases at depths of approximately 100-200 meters (328-656 feet).

The Vent Zone has positive Cu-Au-Ag-Co-REE soil geochemical anomalies and is interpreted as an Iron-Oxide Copper-Gold (IOCG) occurrence. Rock chip sample geochemical analysis results indicate massive and semi-massive chalcopyrite-pyrite mineralization (with minor bornite and molybdenite) contain significant rare earth elements (REE elements Ce- La-Nd-Pr are listed above). The Rocher Mine No 2 & 4 Veins are considered primarily as vein type (tabular shaped) copper resources accompanied by silver, gold and rare earth element bearing minerals.

The distribution of rare earth elements (La-Ce-Sc-Y-Pr-Nd-Pm-Sm-Eu-Gd-Tb- Dy-Ho-Er-Tm-Yb-Lu) are associated with silicified fault zones that have magnetite and massive sulphide. Sulphides & REE do not correlate well. It is unclear whether rare earthbearing minerals are associated with sulphide minerals or re-distributed (re-mobilized) from earlier geological (e.g., pegmatitic phase) events, or a combination of both.

Rare earth elements weakly correlate with increased P, and U/Th. Note- U values ranging between 1.1-19.7 ppm uranium and Th values ranging between 0.12-13.9 ppm thorium are well below threshold values of 100 ppm U. The two main deposit types are observed at the Rocher Mine No 4 & 2 Veins: EARLY FORMING POLYMETALLIC VEIN/BRECCIA: semi-massive and coarse grain (blebby) chalcopyrite with increased magnetite-REE bearing mineralization is related to elevated Cu-Au-Ag-REE in `polymetallic' fissure veins/breccias developed in pegmatitic/aplitic phases of early forming intrusions. LATE FORMING SUB-VOLCANIC VEIN/BRECCIA: massive chalcopyrite, minor bornite-tetrahedrite- arsenopyrite- sphalerite-argentiferous galena bearing mineralization is related to elevated Cu-Ag-As-Sb in `sub-volcanic' fissure veins/breccias.

A drill program is planned on the Rocher Mine 2 & 4 Veins and Vent Zones for 2022.
