Cree communities of Waswanipi (Category III lands), Eeyou Istchee James-Bay territory
Year-round access via the Route de la Baie-James or the Route 1055
Geological Context
Favourable context: Orogenic gold associated with alkaline rocks and porphyritic intrusions
Rivière Waswanipi regional Shear Zone; north and south faults
Shearing affects:
alkaline lavas
polygenic conglomerates (Timiskaming-type) and
porphyritic intrusions
Few drill holes in the area
Rivière Waswanipi showing: 2.36 g/t Au over 1 m associated with 1% pyrite and fuchsite in a qtz-fsp porphyry dyke and an altered lapilli tuff (located 300 metres south of the fault; drilling in 1991: GM 51193)
Observed metallotects related to the geological model
Ductile regional shear zone
Historical showing: Rivière Waswanipi (2.36 g/t Au over 1m)
Metamorphic transition zone favourable for gold mineralisation (CONSOREM study)
Favourable paleopressure zones (CONSOREM study)
Hematite-magnetite-carbonate alteration
Anomalous gold values associated with porphyritic dykes
Gold values in the heavy mineral concentrate of till samples (Inco, 1988)
Concentrations of gold grains in till (Finneth Exploration, 1987)
