Marten Falls and Aroland are not only upset about not aquiring the assets. They had only a small chance.
I think they are even more upset that the North-South route is delayed and possibly history. ( Same for KWG. )
Delayed because Noront as aquirer of the majority of chromite assets in the Ring is not going to develop them at the earlied until 5 years from now. Part of that is probably a bigger burr on their back, it is Muskegowluk with their railway and electrical power proposal.
Of course they could not place their complaints directly at their native neighbours from James Bay. Noront and government are easier targets.
Also no complaining about Webequie and other neighbours along the E-W road route, just Noront for proposing it. If they really had problems with that road they would have raised comments when it was first tabled. It is no wonder as to why Webequie, Naninamik and Neskantaga are not countering when Aroland speeks out. It is inappropriate to be fighting among yourselves, more so in public.
Matawa is fractured when the Ring is the subject.
