Canadian Royalties Inc. (CRI) is a private mining company based in Montreal that operates a copper and nickel mine in Nunavik (province of Quebec), under the name Nunavik Nickel Project (Project). CRI is solely owned by our parent company in China, Jilien Jien Nickel Industry Co., Ltd.

Deposit type

  • Magmatic

Summary:

The five main deposits of the NNP follow an east-west trend spanning approximately 50 km from east to west as follows: Allamaq, Mesamax, Expo, Mequillon and lvakkak deposits.

All the magmatic Ni-Cu deposits at the Nunavik Nickel Project have essentially the same mineralogy. Petrographic work (Walker 2004a, 2004b) identified pyrrhotite (Fe1-XS) as the main sulphide mineral, followed by pentlandite ([Fe,Ni]S) and chalcopyrite (CuFeS2). Pentlandite occurs generally as a separate mineral and only rarely as exsolution lamellae in pyrrhotite. Pentlandite appears to be the main cobalt carrier. Niccolite (NiAs) and violarite (Ni, Fe)3S4 occur only rarely or are entirely absent. Intergrowth of both pentlandite and chalcopyrite with silicate minerals, particularly with serpentine, can be intricate. Magnetite (Fe3O4) is a minor constituent of the rock, the result of the breakdown of the original olivine into serpentine plus magnetite.

Crushers and Mills

Milling equipment has not been reported.

Summary:

The crusher complex will be installed within an insulated flexible structure. The ore trucks will dump on a grizzly (rock breaker included). An apron feeder will move the ore up to the portable jaw crusher (crusher mounted on wheels, Strongco type). The crushed ore will move from one cone breaker to the other via conveyors and screens. The final product will be dumped outside via a conveyor and will be ready to enter the milling process. The flotation circuit separates the grinding circuit discharge into the two sulphide concentrate streams and a main tailings stream. The slurry is first fed to the bulk circuit where the fast floating copper is recovered by the rougher and sent toward the copper circuit to produce a final high grade copper concentrate, while the bulk scavenger recover the nickel and is sent to the Ni-Cu circuit where a nickel concentrate grading from 8 to 12% Ni is produced. The final nickel concentrate is combined with the Ni-Cu concentrate with the copper cleaner tails, which has a nickel content of about 10% to 16% Ni. Both products combined result in a final nickel concentrate grading from 10% to 13% Ni.
