The northern part of the Abitibi greenstone belt, in which the N2 Property is located, consists of east-southeast striking mafic volcanic, pelitic sedimentary, iron formation and mafic to felsic volcaniclastic rock units. Dikes and sills of mafic to felsic composition are common as are larger porphyritic felsic and ultramafic intrusive bodies.
The N2 Property is completely overburden covered. The geology of the property has been pieced together through drilling and geophysical interpretation of the bedrock sub-surface. Regionally the property is interpreted to straddle the boundary between two distinct geological domains. The southern belt, which occupies the southern, Noyon, portion of the property is mafic volcanic dominant with lesser felsic volcanic rocks and ultramafic intrusive lithologies. The northern half of the property is a mixed package of east-southeast trending, interlayered mafic volcanic and sedimentary lithologies. A broad zone of moderate to intense structural deformation is localized around the domain boundary and runs roughly parallel to the local stratigraphy. Later block faulting effects the majority of the property with numerous northeast directed faults evident in geophysical data from the property.
The zone of deformation/faulting located along the domain boundary is known as the Casa Berardi (or Casa-Douay-Cameron) deformation zone and can be traced for over 100 kilometres across the province of Quebec. This crudely east-west trending corridor can be up to two kilometres wide. Numerous splays diverge from the main deformation zone. This is arguably the most complex of the major regional gold-bearing structural zones in the Abitibi.
Regionally gold mineralization, including the producing, multi-million ounce Casa Berardi deposit, the former producing Vezza mine and several advanced prospects, are associated with the Casa-Berardi deformation zone. This is the case for a number of these regional scale structures throughout the Abitibi. Gold mineralization on the N2 property is typically associated with zones of more intense deformation localized along stratigraphic contexts north of the domain boundary.
