About the Kan Property

The Kan Property is located in the Nunavik Territory in northern Québec. The property is a large gold and base-metal exploration project covering a surface area of over 30,000 hectares in the Labrador Trough, 85 kilometres southwest of Kuujjuaq. A silicate-carbonate iron formation of regional extent represents a significant auriferous unit on the property sharing similarities with the world-class Homestake gold deposit. Historical work conducted in the 1990's led to the discovery of numerous gold showings within the iron formation, with drill results returning 5.1 g/t Au over 6 metres (Ferricrete Showing) and 9.46 g/t Au over 2 metres (Kan Showing). Work carried out by Rio Silver Inc. in 2011-2012 yielded 3.12 g/t Au over 13.9 metres in channels and 1.2 g/t Au over 10.4 metres in drilling on the Pump Pad Ridge showing. Exploration work performed in 2014-2016 by Virginia Mines (subsequently Osisko Exploration James Bay) led to the discovery of additional gold mineralization associated with the silicate-carbonate iron formation on the Kan property. Best results from this work include values of: 8.1 g/t Au over 7 metres (Pump Pad Ridge showing); 10.7 g/t Au over 5 metres (Winchester showing); and 8.6 g/t Au over 3.2 metres (KTR showing) obtained from channels; and values of 2.13 g/t Au over 8 metres and 4.62 g/t over 8 metres obtained from drilling (Winchester-Pump-Pad Ridge).
