Nickel pig iron may cause some of Sudbury's mining to be diminished or closed but instead of that being a negative for Noront it may likely be a slight positive. Not only from our cheap production potential ( yes, infrustructure needs completion for that ) but from the mines being idle in Sudbury they would need ore to process to keep functioning and locals employed. That could serve as an incentive for a big cap to take a serious interest in Noront's nickel.
There is already a copper mine idle in Timmins, so the copper with the precious metal is an additional bonus.

Cheers.
