Mineralogy of the Voisey's Bay Ni-Cu deposit, Labrador
Naldrett, A. J.; Singh, J.; Krstic, S.
The Voisey's Bay Ni-Cu deposit is one of the most significant discoveries made in Canada in the last 30 years. Reserves plus indicated and inferred resources amount to 98.5x10' tones at 1.85 wt. % Ni. The deposit can be described in terms of four geological settings; the "Eastern Deeps" consisting of massive and disseminated sulfide along the line of intersection of a feeder sheet with the base of a troctolite intrusion: the "Ovoid", a 600 m long by 350 m wide by 110 m deep lens of massive sulfide underlain by a feeder sheet; the "Discovery Zone" which comprises a series of swellings containings disseminated and massive sulfides in the troctolite feeder, and the Reid Brook zone which is where the feeder sheet opens out into a deeper level intrusion.
