The Flavrian project is characterized by a volcano-plutonic environment prone to mineralization in gold, copper and molybdenum from volcanic, magmatic or metamorphic origin. In fact, all these types of mineralization are known in the area.
MESOTHERMAL QUARTZ-GOLD VEINS
The older phases of the Flavrian pluton contain several gold deposits and showings located in ductile-fragile reverse shears along mafic dykes: Elder (1947 -66, 2.1 Mt @ 5.1 g/t Au); Eldrich (0.7 Mt @ 4.8 g/t Au); Beauchemin (1986 – 93, 2.0 Mt @ 5.1 g/t Au) and Quesabe (1949-51, 90 kt @ 10.0 g/t Au) on Falco’s ground. Globally, these deposits all represent mesothermal gold mineralisations developed late during the geological evolution of the area. These shear zones are characterized by iron carbonate alteration haloes and crosscut all lithologies. They are contemporaneous with regional deformation and metamorphism. The Nora lake showing, revisited by Falco in 2014, belongs to this category.
The western and south western sectors of the property are characterized by several polymetallic gold-copper-molybdenum veins and stockworks of magmatic-hydrothermal affinity (Giant quartz vein, Sylvie, St-Jude breccia, Buffam, McDonald, Martin, etc.). These mineralisations form a crescent shape at least 1 km thick around the south western flank of the pluton and extend from the St-Jude Breccia to the north to at least the old Halliwell mine south of the pluton.
